Abstract: PROBLEM TO BE SOLVED: To distribute audio and video through the Internet by deciding a video or audio format and a bit rate which are suitable for each client and customizing the bit rate of video or audio in a detailed manner. SOLUTION: When a client connects its equipment an Internet convolution audio/video server (ICAVS), the state of a network between the client and the server and the capability of a client system are decided as the occasion demands and they are stored in a client information database 14. For instance, when the client requests audio or video contents, an audio/video data manager 6 searches the contents in an audio/video file server complex 7. Next, a streaming traffic pacer 9 makes audio or video a stream for the client.

Abstract: A method for displaying an enhanced multimedia presentation including personalized supplementary audio, video, and graphic content selectable by a user and rendered by a receiving device, comprises the steps of: communicating a multimedia presentation file to the receiving device, the multimedia presentation file comprising base multimedia presentation content and, frame-synchronized information including starting frame timing identifier, ending frame timing identifier, starting frame spatial coordinates, ending frame spatial coordinates, and motion vector specifications for describing frame-accurate location, motion and timing of the personalized supplementary audio, video, and graphic content, the frame-synchronized information indicating one or more free areas of the multimedia presentation absent significant base multimedia content; extracting the frame-synchronized information from the multimedia presentation file; retrieving the personalized supplementary content from the receiving device; decoding the personalized supplementary content at a time sufficiently in advance of the starting frame timing identifier; and the receiving device selecting an indicated free area and initiating display of one or more items of the personalized supplementary content at frame-accurate times between the starting frame timing identifier and ending frame timing identifier at the frame coordinates in accordance with the frame-synchronized information.

Abstract: The present invention is a method for the coordination and display of graphics or play out of audio or video in conjunction with a multimedia presentation. Graphics objects such as text or sprites, which may be animated, are displayed by the viewer's equipment, which is typically an advanced television or set-top box, which plays the video and audio. Graphics objects are displayed at locations which are complementary to the locations of objects in the video. Similarly, audio or video clips, stored in the set-top box, or embedded in the stream can be played at appropriate times and screen locations in the presentation called video and audio "holes". Data describing these "holes", and other control information is embedded in the video stream and extracted by the viewer's STB for use in coordinating tandem play.

Abstract: A generic high bandwidth adapter providing a unified architecture for data communications between buses, channels, processors, switch fabrics and/or communication networks. Data is carried by data stream packets of variable lengths, and each packet includes a header control information portion required by communication protocols used to mediate the information exchange, and normally a data portion for the data which is to be communicated. The generic high bandwidth adapter comprises a processor subsystem including a processor for processing the header control information portions of data packets. The processor has access to data packets stored in a packet memory which stores data packets arriving at four generic adapter input/output ports. The packet memory is segmented into a plurality of buffers, and each data packet is stored in one or more buffers as required by the length thereof. A generic adapter manager is provided for performing and synchronizing generic adapter management functions, including implementing data structures in the packet memory by organizing data packets in buffers, and organizing data packets into queues for processing by the processor subsystem or transfer to or from generic adapter input/output ports. Each generic adapter input/output port has associated therewith a packet memory interface providing for the transfer of data packets into and out of the packet memory, such that when a data packet is received at an input/output port, the data packet is transferred into the adapter packet memory and queued for processing.
