  • Transcoding video file server and methods for its use
    Patent number: 6188428
    Abstract: The technical field of the invention generally concerns systems for interactive access to stored video data. In particular, a video file server 20 includes both a random access data storage subsystem 78 and a archive data storage subsystem 82 for storing compressed video data. In response to commands from subscriber system 66, the video file server 20 transmits compressed video data to the subscriber systems 66 over lines 64A-64H, or receives compressed video data therefrom. Commands from the subscriber systems 66 may cause the video file server 20 to store compressed video data received from the subscriber systems 66 in the random access data storage subsystem 78 and/or archive data storage subsystem 82. Compression-decompression cards 42 included in the video file server 20 provide an authoring capability for storing compressed video and/or audio data in the random access data storage subsystem 78 and/or archive data storage subsystem 82, and for converting from one data compression standard to another.

  • Adaptive video subscriber system and methods for its use
    Patent number: 5644355
    Abstract: The technical field of the invention generally concerns systems for receiving and transmitting compressed video and audio data. In particular, a subscriber system (10) includes a communication subsystem (12) to receive compressed data from and transmit compressed data to a ISDN primary access line (14) utilizing the "bandwidth on demand" feature of that communication channel. The communication subsystem (12) separates received compressed data into compressed video data and compressed audio data. Within the subscriber system (10), the compressed video data is transmitted to a programmable video data format conversion subsystem (28) for decompression and production of a visible image on a CRT (82). Similarly, compressed audio data is transmitted to a programmable audio data format conversion subsystem (192) for decompression and production of an audible sound on a speaker (262). Compressed data of visible images and audible sounds may also be obtained with and transmitted from the subscriber system (10).
