30 Jun 1994TL;DR: In this article, a video server for providing Video-On-Demand is described, where a plurality of data sources are coupled individually to a first and second bi-directional data/instruction switch.
Abstract: A video server for providing Video-On-Demand is disclosed. A plurality of data sources are coupled individually to a first and second bi-directional data/instruction switch. The first switch is additionally coupled to a data storage system and the second switch is coupled to a network interface. A real time controller is coupled to the data sources and the switches and can couple any part of the data storage system to any selected data source and any given network channel to any selected data source. A control system coupled to the real time controller and the second switch provides support services to the real time controller and acts as a gateway to third party services and products. The data storage system is largely comprised of disk drive arrays. Video data is striped across the individual arrays, each video data program that a user requests being striped across one array. Each array provides video data to many users through the data sources. The video server is tolerant of individual failures in the data storage system and among the data sources, as operating portions of the data storage system and spare data sources can be rapidly switched to substitute for failed units. The server can also be readily expanded and provides a user experience similar to that of a video cassette recorder.

25 Jun 1998TL;DR: In this article, a system for adaptively transporting video over networks wherein the available bandwidth varies with time is proposed, where a video/audio codec that functions to compress, code, decode and decompress video streams that are transmitted over networks having available bandwidth varying with time and location.
Abstract: A system for adaptively transporting video over networks wherein the available bandwidth varies with time. The system comprises a video/audio codec that functions to compress, code, decode and decompress video streams that are transmitted over networks having available banwidths that vary with time and location. Depending on the channel bandwidth, the system adjusts the compression ratio to accomodate a plurality of bandwidths ranging from 20 Kbps for POTS to several Mbps for switched LAN and ATM environments. Bandwidth adjustability is provided by offering a trade off between video resolution, frame rate and individual frame quality. The system generates a video data stream comprised of Key, P and B frames from a raw source of video. Each frame type is further comprised of multiple levels of data representing varying degrees of quality. In addition, several video server platforms can be utilized in tandem to transmit video/audio information with each video server platform transmitting information for a single compression/resolution level.

TL;DR: In this article, an interactive video services system for enabling store and forward distribution of digitized video programming is disclosed, where encoded and compressed digital video signals are transmitted via satellite link from a centrally located uplink site to a plurality of hospitality establishments.
Abstract: An interactive video services system for enabling store and forward distribution of digitized video programming is disclosed In accordance with a feature of the present invention, encoded and compressed digital video signals are transmitted via satellite link from a centrally located uplink site to a plurality of hospitality establishments, where the digitized video programming is stored in the memory of a video server computer or is transmitted "real-time" to the hospitality establishment's customers The establishment either has its own downlink facilities or shares downlink facilities with other hospitality establishments The uplink facility and satellite can transmit a variety of video signals--including video signals for real-time viewing by customers, compressed video signals for storage and subsequent retrieval and viewing by customers, and other types of digitized data, such as advertisements and barker screens Various signal types, including operating system updates and digitized menus and advertisement graphics for the video programming, are separated and appropriately processed and routed at the hospitality facility

TL;DR: In this article, an interactive video services system for enabling store and forward distribution of digitized video programming comprising merged graphics and video data from a minimum of two separate data storage devices is disclosed.
Abstract: An interactive video services system for enabling store and forward distribution of digitized video programming comprising merged graphics and video data from a minimum of two separate data storage devices is disclosed. In a departure from the art, an MPEG converter operating in tandem with an MPEG decoder device that has buffer capacity merges encoded and compressed digital video signals stored in a memory of a video server with digitized graphics generated by and stored in a memory of a systems control computer. The merged signals are then transmitted to and displayed on a TV set connected to the system. In this manner, multiple computers are able to transmit graphics or multimedia data to a video server to be displayed on the TV set or to be superimposed onto video programming that is being displayed on the TV set.

TL;DR: In this paper, an interactive video services system for enabling store and forward distribution of digitized video programming is disclosed, in which encoded and compressed digital video signals are transmitted via satellite link from a centrally located uplink site to a plurality of hospitality establishments, where the digitizedvideo programming is stored in the memory of a video server computer or is transmitted "real-time" to the hospitality establishment's customers.
Abstract: An interactive video services system for enabling store and forward distribution of digitized video programming is disclosed. In accordance with a feature of the present invention, encoded and compressed digital video signals are transmitted via satellite link from a centrally located uplink site to a plurality of hospitality establishments, where the digitized video programming is stored in the memory of a video server computer or is transmitted "real-time" to the hospitality establishment's customers. The establishment either has its own downlink facilities or shares downlink facilities with other hospitality establishments. The uplink facility and satellite can transmit a variety of video signals - including video signals for real-time viewing by customers, compressed video signals for storage and subsequent retrieval and viewing by customers, and other types of digitized data, such as advertisements and barker screens. Various signal types, including operating system updates and digitized menus and advertisement graphics for the video programming, are separated and appropriately processed and routed at the hospitality facility.
