TL;DR: In this paper, a system of distributing video and audio information employs digital signal processing to achieve high rates of data compression, and the compressed and encoded audio and video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.
Abstract: A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression. The compressed and encoded audio and/or video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

TL;DR: In this article, a real-time audio-on-demand communication system is proposed, which provides realtime playback of audio data transferred via telephone lines or other communication links. But, the system is not suitable for multimedia applications.
Abstract: An audio-on-demand communication system provides real-time playback of audio data transferred via telephone lines or other communication links. One or more audio servers include memory banks which store compressed audio data. At the request of a user at a subscriber PC, an audio server transmits the compressed audio data over the communication link to the subscriber PC. The subscriber PC receives and decompresses the transmitted audio data in less than real-time using only the processing power of the CPU within the subscriber PC. According to one aspect of the present invention, high quality audio data compressed according to lossless compression techniques is transmitted together with normal quality audio data. According to another aspect of the present invention, metadata, or extra data, such as text, captions, still images, etc., is transmitted with audio data and is simultaneously displayed with corresponding audio data. The audio-on-demand system also provides a table of contents indicating significant divisions in the audio clip to be played and allows the user immediate access to audio data at the listed divisions. According to a further aspect of the present invention, servers and subscriber PCs are dynamically allocated based upon geographic location to provide the highest possible quality in the communication link.

TL;DR: In this article, an interactive multimedia audio/video communications system uses a lower data rate, non-deterministic graphics/command network having a plurality of desktop viewing stations and a network server.
Abstract: An interactive multimedia audio/video communications system uses a lower data rate, non-deterministic graphics/command network having a plurality of desktop viewing stations and a network server. A separate, higher data rate, deterministic audio/video network is coupled to the plurality of desktop viewing stations using appropriate resources, such as an audio/video routing switcher and a professional disk recorder. A database contains a telephone directory so that when a user at one of the plurality of stations desires to communicate with another station, the user selects a telephone number and the server from the database determines the appropriate resources required to complete the connection. The server configures the necessary hardware via the graphics/command network to route the audio/video signals over the audio/video network from one station to the other. For conferences a quad splitter is used to combine up to four video signals into a singled composited video signal for display at the user's station. For communications with stations that exist on another node, the server communicates with the server at the other node and a codec farm is used to transfer the audio/video signals from the audio/video network of one system to the other. Thus the graphics/command network is left free for normal graphics operations once the audio/video communications has been established.

TL;DR: A remotely controllable computing and multimedia entertainment system includes a personal computer (24) having an entertainment circuit (12) made up of a radio frequency circuit (48), a television circuit (46), and an audio multimedia circuit (18) as mentioned in this paper.
Abstract: A remotely controllable computing and multimedia entertainment system includes a personal computer (24) having an entertainment circuit (12) made up of a radio frequency circuit (48), a television circuit (46), and an audio multimedia circuit (18). A remote control circuit (50) provides programmable control of the entertainment circuit (12) to select among computer function operation, television and radio operation, and audio operation. An analog mixing circuit (70) within the audio multimedia circuit (18) provides mixing for a plurality of analog audio signals. A telephone circuit (44) integrates data, fax, and voice telephone signals in the entertainment circuit (12). A volume control circuit (318) within the audio multimedia circuit (18) provides varying volume, bass, and tone levels for each audio signal received by the analog mixing circuit (70). The analog audio signals received by analog mixing circuit (70) may include monaural and stereo audio signals.
