摘要： Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. The requests may be for the same or different video programs. The requests for the video programs may occur at the same or at different times. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex.

摘要： A system for providing efficient constant bit rate distribution of variable bit-rate encoded video programs while facilitating the distribution of encoded video programs, along with Auxiliary Data of a general character, to one or more receivers. At a particular receiver, a customized augmented video program is created by inserting selected portions of the Auxiliary Data into a selected encoded video program. The encoded video portion of the augmented video program can be transmitted, decoded and displayed in real time, while the Auxiliary Data need not be transmitted in real time but can be stored locally at the receiver for real-time presentation at a later time. Real time presentation might include insertion into the video program while non real-time presentation might include insertion into non-video applications separate from the video program.

摘要： A compressed video playback system which eliminates playback mode transition artifacts. Transitions between various playback modes are effected in such a manner that transition artifacts are eliminated by delaying playback mode transitions until appropriate frames of data are detected for propagation to the compressed video decoder. In addition, compressed video data retrieval methods are improved for supporting multi-speed playback modes in both forward and reverse directions in an optimal manner.

摘要： Virtually random and on-demand access is provided to a virtually unlimited number of subscribers by partitioning the video program into an ordered sequence of n segments and providing the subscribers concurrent access to each of the n subsequences. A data stream representative of the video program is partitioned into n subsequences, each representative of one of the n segments. The data of each of the n subsequences is organized as an ordered sequence of elements. The elements of each of the n subsequences are interleaved and the interleaved data stream is continuously transmitted over a video program distribution medium at a rate which renders the data representing each segment concurrently available to any subscriber having a receiver capable of selecting, assembling, and displaying the data of a particular segment. The data stream can be compressed prior to interleaving using one of many known video data compression standards and techniques. Data compression can be performed in real time, or iteratively using software. The interleaved data stream can be transmitted in real time, or it can be stored on a storage device such as a hard disk or optical disk for later retrieval and transmission. The interleaved data stream can be ordered using any known standard by which video data is transmitted for reconstruction and display by a receiver. Data can be inserted into the interleaved data stream to inform the receiver to which of the n segments a portion of the interleaved data stream belongs, as well as the encoding level necessary for decompression of the data and time stamps to indicate order of display.

摘要： An apparatus for providing VCR-like “trick mode” functions, such as pause, fast-forward, and rewind, in a distributed, video-on-demand program environment. Trick modes are supported by locally altering the viewing speed for each user who requests such functions, without affecting the operation of the central data source in any way. Thus, a virtual unlimited number of viewers are able to enjoy random access to video programming, including virtually continuous trick mode functionality. This is accomplished in a manner that is operable with existing telephone and cable distribution infrastructure.

摘要： An digital home video system providing recording and playback of compressed video programs using an archival storage medium; simultaneous recording and playback using the same archival medium; storage of multiple programs on a single videotape; a full array of trick mode functions; efficient management of the contents of a video tape or other archival storage medium; and real-time random access to video program content, enabling truly interactive playback. These capabilities are provided by combining the best features of an archival storage medium such as digital video tape: namely, potentially large storage capacity, but low tolerance for variable data rate, and essentially linear program access; with the complementary features of a relatively high-access storage device such as a fixed disk drive: namely, tolerance for a highly variable data rate, and random access capability, but relatively lower storage capacity.
