Abstract: The present invention provides a media stream playing method and a set-top box. In the present invention, in a process that a guidance unit of a set-top box initializes a platform system, the guidance unit obtains a channel identifier of a channel to be played and obtains, by using the channel identifier, a media stream that corresponds to the channel identifier, so that the guidance unit can send the media stream to a playing unit of the set-top box for playing. Because the technical solution is independent of the platform system of the set-top box, a problem in the prior art that, the set-top box cannot perform a television play service in an initialization process of the set-top box and the set-top box can perform the television play service by using the platform system only after the initialization of the set-top box is completed, can be avoided.

Abstract: To effectively utilize the bandwidth of a cable TV network, which is limited, analog TV program material is digitized and compressed before its transmission over the network. The resulting signals consume only part of the analog TV band traditionally needed for transmission of the analog TV program material. The newly available bandwidth in the analog TV band may be utilized for other cable TV services, e.g., video-on-demand (VOD) services. A reception gateway is employed at a user location to frequency-translate any VOD signals, transmitted through the analog TV band, to another frequency band, thereby avoiding disturbing the normal operation of a set-top terminal in receiving the analog TV program material through the analog TV band at the user location.

Abstract: A digital electronic device supports program transmission to a recipient device via the Internet. A frame adapter decodes incoming IP program packets and re-encodes resulting program signals adaptively to optimally suit the recipient device based upon configuration data of the recipient device. The frame adapter receives feedback from the recipient device, which may include a characterization of a communication path between the digital electronic device and the recipient device. The frame adapter utilizes the configuration information to generate the optimal video frame stream that is transmitted to the recipient device. The compression itself involves producing optimal number of base and predicted video frames.

Abstract: The present invention improves the performance of video on demand (VOD) in a digital cable system. A statistical remultiplexer (stat mux) acquires metadata that statistically describes the bandwidth characteristics of each VOD channel. When the metadata indicates that the VOD channel will require more bandwidth than is available, the stat mux can re-encode or re-compress other streams or the VOD stream streams to meet the bandwidth limitation. The metadata is generated off-line and streamed out ahead of the VOD program content. The stat mux includes a minimal length buffer for storing VOD program content that when combined with the metadata enables a viewer to randomly access VOD program content without noticeable latency. When a VOD function request is received from the viewer, the previously supplied metadata is used to allocate bandwidth rather than waiting for a look-ahead buffer to acquire a sufficient amount of future VOD program content.

Abstract: The present invention relates to a method, a terminal and a server for allocating a signal route resource in a Video On Demand (VOD) service.

Through a signal route detection method, a location of a VOD terminal device is automatically identified, so that roaming of the VOD terminal device may be realized, and when a coverage relation of the terminal is changed, the VOD service may be normally supported without any additional processing.

Abstract: A computerized method for determining a model refresh rate for a model representing a list of network user identifiers includes receiving a first and a second model representing the list at a first and a second time, respectively.

Abstract: A switched broadcast service and a network personal video recorder (NPVR) service are provided synergistically in a cable TV system having limited resources. For example, in providing the switched broadcast service, a resource manager allocates network bandwidth for broadcast of materials from selected program channels on an as needed basis. Such allocation is conducive to an effective provision of the NPVR service which requires dedicated bandwidth for transmitting recorded broadcast program material in a headend to each set-top terminal requesting the NPVR service. Thus, unlike the switched broadcast service where a program stream containing program material is shared by one or more set-top terminals, the NPVR service provides a dedicated program stream to each set-top terminal so that a user at the terminal may manipulate (e.g., rewind, pause and/or fast-forward) a presentation of program material at will.
