A multimedia server receives a plurality of programs of a multimedia source. The multimedia server includes a tuning module to receive the plurality of programs and to select a set of programs from the plurality of programs based on a set of program select commands that is derived from select requests. A program mixer mixes the set of programs into a stream of program data. One or more transceiving modules transmit the stream of program data on to corresponding communication paths and receive the select requests. A client module produces the select requests for one or more clients. The client module includes a selection module to produce at least one of the select requests. A network interface controller transmits at least one of select requests to the multimedia server and receives the stream of program data via the communication path or paths in response.

Method and set top box for use in a multimedia system

A local system encodes previously decoded video data using a transcoding quantization value based on a source quantization value provided by a previous encoder as part of the retrieved video data. The transcoding quantization value can be determined additionally based the fullness of the video buffer of a target system, where a measure of the fullness can be obtained directly from the target system or modeled by the local system. The video data is encoded by the local system and then provided to a target system for decoding and subsequent display and/or storage.

Method and system for rate control during video transcoding

A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and the state machine executes a process of selecting at least one stream as a target for lowering total bandwidth usage. Once the target stream associated with a client receiver unit is chosen, the amount of data transmitted by the target stream is reduced, which could result in a lower data transmission rate. In one embodiment, the amount of data is reduced by a gradual degradation of the precision of the data, resulting in a greater potential for data compression, and/or by gradually reducing the resolution of the data of the target stream.

A system for processing a video signal into a processed video signal includes a video codec configured to generate a processed video signal based on the image sequence. A photo generation module is configured to recognize an object of interest in the image sequence and generate photo data from a selected image in the image sequence that includes the object of interest.

Video processing system with photo generation and methods for use therewith

Aspects of the subject disclosure may include, for example, a video camera system that includes a first subset of video cameras that are configured to generate at least one broadcast video signal of an event, and a second subset of video cameras that are each individually controllable in response to subscriber control data from a corresponding one of a plurality of video player systems to generate a plurality of processed video signals of the event. A video access server receives the subscriber control data from the video player systems corresponding to a plurality of subscribers for control of the second subset of video cameras, and for routing the processed video signals of the event such that each of the plurality of processed video signals of the event is routed to the corresponding one of the plurality of video player systems. Other embodiments are disclosed.

A video processing device includes a content analyzer that receives a video signal and generates content recognition data based on the video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal. A metadata search device generates time-coded metadata in response to content recognition data and in accordance with the at least one time stamp. A metadata association device generates a processed video signal from the video signal, wherein the processed video signal includes the time-coded metadata.

Video processing device for generating time-coded metadata and methods for use therewith

A viewer fovea tracking generator is configured to analyze image data corresponding to a viewing of the video program via an A/V player by at least one viewer, and to generate fovea tracking data corresponding to the at least one viewer. A network interface configured to transmit the fovea tracking data to the video source via a network. The video program is fovea encoded by the video source in accordance with the fovea tracking data.

Video system with fovea tracking and methods for use therewith

A video processing device includes a video processing unit that decodes a video input signal into a decoded video signal in accordance with a video compression protocol, based on uncompressed video frame data. A data object compression/decompression module generates compressed video frame data by compressing a plurality of video data objects into a plurality of compressed video data objects, storing the plurality of compressed video data objects in a compressed frame buffer. The data object compression/decompression module retrieves a selected portion of video frame data from the compressed video frame buffer by identifying selected ones of plurality of compressed video data objects that correspond to the selected portion of video frame data, retrieving the selected ones of the plurality of compressed video data objects and generating the uncompressed video frame data by decompressing the selected ones of the plurality of compressed video data objects.

Video processor with random access to compressed frame buffer and methods for use therewith
