Abstract: A system that relates annotations captured at an event and continuous signal recordings, such as video recordings, of the event in such as way that once the recordings and annotations are distributed to a remote site, an operator does not have to manually identify the time intervals of individual segments that are identified in the annotations. Prior to distribution to the remote sites, the annotations that are collected for the event are processed to identify a series of time segments, including a time interval of the signal recordings. The time reference for these identified time intervals is based on the signal recordings themselves, for example, being relative to a time reference marks that are introduced into the video recordings before they are distributed to the remote site, or being based on an recorded time signal.

Abstract: A play to air controller station system in a distributed object television broadcast studio. In one embodiment, a play to air control workstation is used to control a variety of resources in a broadcast studio system interconnected by a communications network. The resources of the broadcast studio system include a transmitter unit, various media source devices such as tape decks and file servers, a network routers unit, and various decoders and encoders. The broadcast studio system is managed as a network distributed object system where an all physical devices are attached to the network either by containing appropriate software within themselves, or by attaching themselves to a computer proxy that is on the network and is able to control their functionality. The control system includes one or more device objects configured to store, route and transmit selected video segments to be aired from the television broadcast studio.

Abstract: A national level information service system collects local and national interest information and advertisements from a plurality of remote providers that may be located around the country or the world, and distributes this information to one or more television distribution systems for viewing by the system viewers. The system provides timely information relating to various areas of interest, including, for example, news, sports, weather, stock information and the like, that can be viewed on one or more television channels. Providers of the national and local interest information periodically collect the raw data containing the information to be broadcast, and store the data at a designated location, preferably on the provider's Internet server. These stored files are then periodically retrieved and compared to previously retrieved files to determine whether they have been updated by the information provider.

Abstract: A method for facilitating the electronic scheduling for playback of a variety of media such as music or video is disclosed. In the described system, discrete items of content (such as music or video) are scheduled for play back based upon a schedule created by the integration of five standard scheduling methods into a single comprehensive scheduling algorithm. In the first scheduling method a discrete item of content is assigned a frequency rating relative to other items of content. A second way to schedule is called recurring playback. In the recurring method, a particular item of content is scheduled to repeat at specific intervals of time. Intervals can be in terms of minutes, hours or days. A third scheduling method allows the content to be played according to a time base, that is, media content can be scheduled to play at a specific date and time. The forth type of input to the scheduling system is a trigger event which is received from a source external to the scheduling system.

Abstract: A cable television distribution system in which the head end substitutes different channels for a plurality of separated geographic zones. The head end creates a plurality of channel spectrums and transmits the spectrums on distribution trunks such that a different spectrum may be present on each distribution trunk. The spectrums on the distribution trunks are connected to zones of the viewer community which have been selected for market research purposes on the basis of demographics.

Abstract: A decoder is used in an end-to-end scalable video delivery system operable over heterogeneous networks. The decoder may software-based and computationally low complexity, or may be implemented inexpensively in ROM hardware. The system utilizes a scalable video compression algorithm based on a Laplacian pyramid decomposition to generate an embedded information stream. At the receiving end, the decoder extracts from the embedded stream different streams at different spatial and temporal resolutions. Decoding a 160×120 pixel image involves only decompressing a base layer 160×120 pixel image. Decoding a 320×240 pixel image involves decompressing and up-sampling (e.g., interpolating) the base layer to yield a 320×240 pixel image to which is added error data in a first enhancement layer following its decompression.

Abstract: The present invention which involves a digital broadcasting system provides a digital broadcasting method in which change information NETQ for indicating the broadcast content change is transmitted a certain period of time in advance by a primary transmission system when the primary transmission system broadcasts programs. As the result, a secondary transmission system, for example, a cable television system which reedits and rebroadcasts the programs received from a digital satellite broadcasting system, can easily and quickly rearrange the air time in response to the change such as program content change in the rebroadcasting in the secondary transmission system.

Abstract: A system and method for capturing and processing audio and video images for optimized transmission over a lower bandwidth communications channel are disclosed. A digital processing system receives video and audio signals from a media source such that the video and audio signals are representative of captured images and sounds as a multimedia signal. An optical processing system is coupled to the digital processing system and performs signal processing algorithms on the multimedia signal. A transceiver transmits the multimedia signal over a lower bandwidth communications channel wherein the multimedia signal is optimized for transmission over the lower bandwidth communications channel by the signal processing algorithms performed by the optical processing system.

Abstract: In an interactive cable system having a plurality of assignable interactive controllers which communicate with subscribers through an information service distribution network, a frame server is provided for interfacing with a plurality of subscribers. A system manager assigns either the frame server or one of the plurality of interactive controllers to subscribers requesting interactive service. The frame server preferably delivers interactive pages which need only be transmitted intermittently, such as still frame images.
