    摘要: The present invention is directed to a videophone system implemented over a cable television network. The instant invention provides a videophone comprising a camera for capturing images associated with a videophone signal, a videophone unit and a set top terminal or cable modem connecting the videophone to a cable television network. Videophone signals created at the call origination site are encoded and transported to a predetermined destination over an existing cable television network. The system uses IP addresses as phone number on the network. Additionally, transport of videophone signals between different cable systems is accomplished via a high-speed long distance data network, such as, for example, a satellite network, that provides communication between the headends of the different cable television systems. The set top terminal may be a conventional subscriber terminal, a cable modem or a subscriber terminal configured to operate as a cable modem. The set top terminal provides the interface between the videophone and the cable television system. More than one videophone may be connected to a single set top terminal. Display of videophone data may be achieved using any conventional display device, including a television set or a personal computer monitor. Accordingly, the videophone system described herein takes advantage of increased bandwidth and lower cost realized by using existing cable television infrastructure and technology.

    摘要: In a subscriber television system, assigning categories to a channel as an entity reduces the searching requirements associated with searching a database of thousands of individual program records, identifying the channel on which an identified program will be displayed, and then sorting the resultant information. The channel information is searched for the assigned category information and the associated program information for just those channels is retrieved. This reduces the processor requirements for searching the thousands of records in the program records database. With the reduced processor requirements and the increased efficiency of information organization for searching, a single machine state change is possible between viewing full screen video and a browse banner or between viewing full screen program information and video with a browse banner.

    摘要: A system that stores plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene, receives first and second measures of plural successive pictures corresponding to a first video scene received from a remote device, the first and second measures corresponding to measured transitions of a video object of the first video scene, compares the first and second measures with the stored plural reference measures, and indicates to the remote device whether a threshold percentage match exists between the first and second measures and one of the stored plural reference pictures.
