Definitions
- This invention relates to a system and apparatus for controlling the flow of data from multiple sources. More specifically, the invention relates to a system and apparatus for automatically combining data from multiple sources to form a composite data stream.
- streaming media provides an efficient way to deliver live performances, television broadcasts and similar events to Internet users.
- streaming media includes a set of images and sounds that are sent over the Internet, and played for the viewer in sequence as they arrive. Without streaming media, an Internet user would have to download an entire file before any audio or video could be played. Downloading such a file, which is usually very large, often consumes a substantial amount of time and is typically the source of considerable frustration.
- the availability of streaming media broadcasts encourages companies to insert advertisements and other information into the media stream as it is delivered to users over the Internet.
- the invention is generally directed to a system for controlling the flow of data from multiple sources to generate a composite information stream.
- the system includes a plurality of data sources linked to a flow control system.
- the flow control system is configured to receive data from two or more of said plurality of data sources and from a data control manager, to selectively insert data received from the plurality of data sources into the data stream in response to commands from the data control manager, and to pass the merged data to an encoder.
- the data includes commercial advertisements.
- Files that contain the advertisements are downloaded to a computer that is linked to the encoder.
- the data control manager can also compile a list of the advertisements that have been transmitted to the media player.
- FIG. 1 illustrates a system that is capable of delivering a composite information stream over a computer network in accordance with an embodiment of the invention.
- FIG. 2 contains a detailed illustration of a flow control system linked to associated hardware in accordance with an embodiment of the invention.
- FIG. 3 is a block diagram that shows one way in which data can be selectively transmitted from multiple sources according to an embodiment of the invention;
- FIG. 4 is a schematic illustration showing a flow driver linked to a flow controller in accordance with an embodiment of the invention;
- FIG. 5 is a block diagram that illustrates in detail the manner in which stored data may be delivered to the flow control system in accordance with one embodiment of the invention
- FIG. 6 is a block diagram that illustrates in detail the manner in which stored data may be transferred to end user processors in accordance with one embodiment of the invention
- FIG. 7 illustrates data from multiple sources simultaneously being displayed on a video monitor
- FIG. 8 shows how an event can trigger the display of data a video monitor in accordance with the invention.
- FIG. 1 illustrates schematically, a system 100 which delivers a composite information stream over a computer network, such as the Internet.
- composite information stream refers to a stream of information that could include one or more of several different items or types of data either sequentially or in some simultaneous combination.
- a composite information stream could include live data from a television broadcast, data that is located on one or more storage devices such as a digital video disc (DND) player, a video cassette recorder (NCR), a personal computer, various files from a file storage device, etc. or it could include some combination of data from these sources.
- DND digital video disc
- NCR video cassette recorder
- the stream could contain live data, then stored data, then live data.
- composite information is described as being part of a "single" stream, those skilled in the art will recognize that the various types of data could be split or duplicated, or that subsets of the data could be combined to generate two or more streams, each of which contains multiple types of data. While the delivery of such information over the Internet is a common use for system 100, it is to be understood that it could be used to deliver information over a local area network (LAN) wide area network (WAN) or other system.
- LAN local area network
- WAN wide area network
- System 100 generally includes multiple end user processors 102, a streaming media server 104, a web server 106 and a flow control system 10.
- flow control system 10 communicates with multiple information sources 12, 14, 16 and 18 to insert the data from these sources into a composite information stream.
- End user processors 102 typically include an Internet browser, such as Internet Explorer or Netscape Navigator, and a streaming media player such as Microsoft Windows Media Player, or Real Networks' Real Player.
- Various web sites are linked to system 100 by web server 106 for viewing by end users 102. End users 102 may access streaming media and various other forms of content by viewing web sites and selecting various links.
- flow control system 10 typically provides an intermediate link between an encoder 26 and a media delivery device 24, and it generally includes various computer executable files.
- Media delivery device 24 typically includes a capture portion which receives data from one or more input sources and a driver portion which forwards the received information to one or more output sources.
- flow control system 10 is an independent module, physically separated from the media delivery device (e.g. in a separate electronic box or unit), yet linked to it to allow communication with at least the driver portion.
- Exemplary media delivery devices that may be used in accordance with the invention include audio cards such as those manufactured by Crystal Semiconductor, Inc. and Antex Electronics Corp. and video cards such as those manufactured by Osprey Communications, Inc.
- Encoder 26 is generally of the type that communicates with a streaming media server 104 to transfer an audio and/or video data stream from a radio or television broadcast to a media player as previously described.
- media delivery device 24 flow control system 10 and encoder 26 are located in separate electronic boxes.
- delivering a composite information stream to end users 102 in accordance with the invention typically begins by loading startup information in encoder 26 as indicated in block 202.
- the invention may be used with the Microsoft Windows Media Player.
- startup information will typically be provided in a configuration file that identifies the driver that will be used to deliver audio and/or video data from media delivery device 24.
- the configuration file will identify the device driver 36 that will be used, and may also describe the format in which the data should be delivered to encoder 26.
- a command in the configuration file (which was loaded into the encoder memory at step 204) directs encoder 26 to deliver a composite information stream.
- Flow control system 10 is then loaded into the encoder memory as shown in block 206.
- Encoder 26 initializes flow control system 10 and delivers the data format and device driver information that was obtained from the configuration files as shown in block 208.
- flow control system 10 loads driver 36, initializes it and sets up a callback routine to enable encoder 26 to receive audio and or video data from driver 36 as shown in block 210.
- Flow control system 10 passes the media data that it receives from driver 36 to encoder 26 at block 212, which forwards the data to the media player at end users processors 102.
- flow control system 10 determines from the startup information whether information from one or more alternate sources will be inserted into the media stream as indicated in block 214. More specifically, flow control system 10 continues to pass data from the media delivery device until it receives a signal that data from an alternate source should be inserted. When such a signal is received, flow control system 10 selects the designated alternate source as indicated in block 216, and passes data from the selected source to encoder 26. The data from this alternate source will be inserted into the data stream until the entire file has been delivered to encoder 26. Once the file has been inserted into the stream, flow control system 10 returns to block 214 to determine whether another alternate source should be selected to transmit another file.
- flow control system 10 controls the flow of data from multiple sources to deliver a composite information stream to end users 102.
- two or more data sources 12, 14, 16 and 18 are linked to flow driver 20. As shown, some sources may be linked to flow driver 20 through media delivery device 24 (e.g. sources 12, 14 and 16), while others (e.g. source 18) are linked directly to flow driver 20.
- Sources 12, 14 and 16 may provide analog data that will be converted to digital data by media delivery device 24, or they may provide digital data that is forwarded to encoder 26 with limited (or no) processing.
- sources such as data source 18 that are directly connected to flow driver 20 will typically be provided in digital form, or include an analog to digital converter or other device that will enable the data to be converted to a digital format prior to its delivery to flow driver 20. While the illustration shows multiple data sources 12, 14 and 16 connected to media delivery device 24 and only a single source 18 connected directly to flow driver 20, it should be understood that multiple sources could be directly connected to flow driver 20 and/or that a single source could be connected to media delivery device 24.
- flow driver 20 selectively passes data from data sources 12, 14, 16 and 18 to encoder 26. Encoder 26 then returns to media delivery device 24 and continues merging data it provides into the composite stream. The information is then forwarded to the appropriate media player at end user processor 102 and displayed on a video monitor, personal digital assistant screen or other output device.
- sources 12, 14, 16 and 18 may include live data, such as, for example, that from a television broadcast and one or more video cassette recorders, digital video disc players, digital satellite systems, and similar devices.
- Sources 12, 14, 16 and 18 may also include computers and other devices that provide stored data such as audio video interleaved files and graphics interchange files.
- Signals that trigger flow control system 10 to pass data from one of the additional sources will preferably be embedded or otherwise included in the broadcast. As stated earlier, these may be audible signals, such as tones or beeps, or they may be some other indicator that may be used in accordance with the invention. Signals could be used as they are delivered, or they could be embedded in the broadcast in one format (e.g. as an audible tone), and converted to another format (e.g. an electrical impulse) if desired.
- flow driver 20 could be triggered to vary the transmission source when the signals are provided independently such as, for example, by a timing device, by a computer that has been programmed to generate signals at an appropriate time, or by a manual process.
- While the invention is described herein as delivering information from a single media delivery device 24 at a time, it is to be understood that the invention could be configured to simultaneously pass data from multiple devices.
- several encoders 26, each of which is linked to a separate flow control system 10 could be linked to communicate with a single end user processor 102.
- Different media delivery devices 24 could then communicate with each flow control system to provide different types of data.
- Such an embodiment of the invention could be used, for example, to deliver a composite information stream that includes data from two or more audio and/or video drivers as well as one or more DND players and NCRs.
- the output of a single flow control system 10 could be sent to multiple encoders 26, each encoding in a different manner. For example, it is often preferable to encode different types of information at different rates. More specifically, while some end users are connected to the Internet using 28 kbps modems, others are connected using 56 kbps modems. Using known devices, data encoded at different rates would have to be passed to different encoders 26, before they could be displayed on the associated output devices. According to an embodiment of the invention, information that is delivered to flow driver 20 by sources 12, 14, 16 and/or 18 may include signals that identify the appropriate encoding rate. Encoder 26 may be configured to read these signals to encode the data as directed.
- flow driver 20 receives various commands from data control manager 32, which is typically an externally located software component.
- Data control manager 32 is used to designate the order in which data will be received from sources 12, 14, 16 and 18, encoded into a composite stream, and transmitted to end users 102.
- flow control system 10 can be used to combine many types of data for delivery to end users 102 as a composite stream.
- flow control system 10 may provide updated information about content in a program that is being broadcast. For example, during a broadcast of a sports event, flow control system 10 may provide updated statistics about a player or team that is involved in the event. In another embodiment, information that allows a viewer to contact the appropriate source to order products or services that are associated with the program content may be provided.
- flow control system 10 inserts commercial advertisements ("ads") into a television broadcast.
- the order in which the connected sources are selected to transmit data is stored in queue 22.
- the transmission order stored in queue 22 can be obtained in numerous ways, such as in a pre-programmed list, a computer program or interactively.
- the list may be transferred or downloaded from another location, such as a personal computer that is directly connected to queue 22 or that is connected to queue 22, for example, via a local area or wide area network including, but not limited to the Internet.
- telephone lines may be used to provide the information that is used to control the order in which data is transmitted from data sources 12, 14 16 and 18.
- the user may press the various buttons on the telephone key pad or dial to select numbers that are associated with the different data sources 12, 14, 16 and 18 to designate the order in which data should be transmitted from those sources, hi another such embodiment, it may be desired to enable the system to recognize voice commands and convert them to a digital format as provided by sound cards such as those manufactured by Dialogic Corporation, Parsippany, NJ.
- the addition of such a device may allow a user to state a number that identifies the appropriate data source, or to state one or more words that identify the data that will be transmitted, such as the title, the name or subject of an advertisement.
- voice recognition software may be incorporated directly into flow control system 10 to allow the user to issue such voice commands without the use of a Dialogic card.
- flow control system 10 When delivering commands via telephone lines, it may be desired to adapt flow control system 10 to require users to enter a personal identification number or other identifying information in order to prevent unauthorized changes from being made.
- Those skilled in the art will recognize that the invention could also be adapted to accommodate the use of cellular telephones, personal digital assistants and other wireless devices.
- data control manager 32 communicates with web server 106 to obtain the data that will be stored in source 18. More specifically, data control manager 32 passes parameters that indicate the type of encoder 26 that is connected to flow control system 10, and the application that will be used to deliver the data that is stored in source 18, as well as the duration that will be available for playing the data (i.e. "break length" in the case of an advertisement file), and the type of files (e.g. AVI, WAV) that can be stored. In response, web server 106 provides a list of the names of files that have been previously delivered to the encoder that satisfy the parameters. The actual files may be delivered to encoder 26 in several ways. For example, in one embodiment of the invention, the files are downloaded from web server 106 via a scheduled job. Such a job could run at scheduled intervals to deliver new file.
- flow control system 10 selects an alternate source and passes data from the selected source until the desired amount of data has been delivered to encoder 26.
- this portion of the invention operates as shown in FIGS. 5 and 6.
- data control manager 32 sends a command to flow control system 10 to set up queue 22 as indicated in block 402.
- the various data files that may be delivered by sources 12, 14, 16 and 18 are associated with identifiers, which are typically numerical values.
- the set up of queue 22 in block 402 typically includes placing the numbers that are associated with these files in the order in which the files are to be delivered to encoder 26.
- data control manager 32 sends the name of the file that is associated with the number provided by queue 22 to flow controller 10 at block 406.
- the named file is then loaded from the selected source into a memory linked to encoder 26 at block 408.
- the file is converted to a format that can be used by encoder 26 as indicated in block 410 and is stored in the encoder 26 memory.
- the converted data file is passed to the media player at block 412 for display on end user processors 102.
- a unique data identifier is also passed to data control manager 32 at block 414 to indicate that the requested data has in fact been transmitted to encoder 26.
- information about the files that are transmitted to the media player can be used by other applications. For example, the system can be set up so that each time a commercial advertisement is transmitted to the media player, data control manager 32 memorializes the event to create an advertisement log that can be used to show what advertisements have been played.
- data control manager 32 will refill queue 22 with new file information and reset it.
- the invention may be used to deliver information to a Windows Media Player. These embodiments of the invention will typically carry out file conversion using application programming interfaces that are provided by a software development kit, such as those that are provided by Microsoft Corp. to convert files for use by various media players.
- the data that is downloaded from web server 106, stored in source 18 and transmitted to encoder 26 includes commercial advertisements.
- the assignment and transmission of unique identifiers allows for the tracking of the advertisements, and provides a way to verify that requested advertisements have been played.
- computer generated files such as audio video interleaved files and/or a graphics interchange files are stored in source 18. These files may be compressed, for example, to comply with JPEG and/or MPEG standards. It should be noted that the system that is placed between the computer generated data and flow driver 20 may perform "AND” and "OR” operations. Thus, in one embodiment, flow controller 10 may direct flow driver 20 to transmit data from only one source 12, 14, 16 or 18. In such an embodiment, the data from both sources may be passed to flow controller 10, which will dictate which of the two sources should be connected to flow driver 20 for the transmission of data.
- flow controller 10 may direct flow driver 20 to simultaneously transmit data from two or more sources 12, 14, 16 or 18. Such an embodiment may, for example, allow an image 44 from a television broadcast to simultaneously be displayed with a symbol 42 such as a logo or a watermark that identifies a sponsor, content provider or other entity that may be associated with the information that is being transmitted. In this embodiment, flow controller 10 may direct flow driver 20 to receive the data from both sources to cause both sources to pass data to encoder 26 simultaneously.
- the occurrence of one or more events may be used to initiate the transmission of data from sources 12, 14, 16 and 18.
- information from a live telecast 46 such as a sports or news event may be transmitted to one or more data sources 12, 14, 16 and 18.
- Queue 22 may then select the appropriate data source when it receives an appropriate signal (e.g. at the beginning or end of the event), to insert information 48 which may include video clips, still images, reports, highlights, summaries, scores or other information from the event into the video stream.
- breaking news may be fed to one of data sources 12, 14, 16 and 18 along with a signal that triggers flow control system 10 to immediately transmit the data from the source.
- a broadcast may then be interrupted to provide the breaking news to the viewer in response to the signal.
- video from a sports event may be fed to one of data sources 12, 14, 16 and 18.
- a signal may be generated to indicate that the event has concluded, to cause queue 22 to select the associated data source when the next (or a designated) signal that is embedded in the broadcast is received, to display the final score and to play a video clip with highlights of the event.
- signals may be assigned different priority levels, to cause some information to interrupt broadcasts when necessary and to allow the system to deliver other information only at regularly scheduled breaks.
- tones that are embedded in a broadcast may be detected by data control manager 32 using a hardware based detection procedure.
- a signal may be transmitted to a software component that runs on a device that is external to flow control system 10 when such tones are detected.
- the software component on this separate piece of hardware may then send a command to data control manager 32 to request playing of the ad designated by queue 22.
- the command is then forwarded to flow control system 10 which selects and plays the ad.
- a signal is preferably transmitted to data control manager 32 when flow control system 10 finishes playing the ad, and queue 22 is filled with another ad.
- data control manager 32 sends a command to flow control system 10 to cause an ad that was identified during queuing to be played.
- a software based tone detection process may be included in flow control system 10 and data control manager 32 may use this process to encode information from the various sources into the composite data stream, hi such an embodiment, tone control software may be loaded into flow control system 10 and the audio and/or video data that has been captured may be analyzed to determine whether any tones are present. A detected tone is interpreted by flow control system 10 as an event (described earlier), which is forwarded to data control manager 32. In response, data control manager 32 may send a command back to flow control system 10 to cause the specified commercial to be played. In this embodiment, data control manager 32 would initially configure flow control system 10 to set up the frequencies that will trigger an event in data control manager 32.
- encoder 26 may be configured to read signals that identify any or all of the numerous parameters that relate to how the information should be displayed, such as whether the information being transmitted will be displayed in monochrome or in color, whether it includes a monophonic or stereophonic broadcast, the appropriate frame size. etc.
- the information that is received by encoder 26 may be routed through the appropriate portion of the circuitry in order to accommodate the requirements that are imposed by these parameters.
- any or all of the above described and similar functions could be incorporated into a single computer, or that these functions may be incorporated in accordance with the choices of Internet users, content providers or others. It should also be noted that any or all of the actions that are conducted by flow control system 10 may be tracked and stored in a file or otherwise provided in a log, in order to assist with billing or other appropriate operations.
