摘要： A method and apparatus for controlling access to a video system based on bandwidth consumption include processing that begins as the server monitors bandwidth utilization of connections within the video system. The processing continues when the server receives a request to access a video program via the connection from a client device of the video system. The processing then continues as the server determines whether determine whether the client device has subscribed to receive the video program at the first quality level. When the client device has not subscribed to receive the video program at the first quality level, the video quality of the video program is converted from the first quality level to a video quality subscribed to by the client device.

摘要： 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.

摘要： A method and apparatus for customize messaging within a cable system includes processing that begins by obtaining a user profile of a user of the cable system. The processing continues by obtaining audience specific messages that includes a desired user profile. The desired user profile indicates targeted user profiles. The processing then continues by comparing the user profile of the user with the desired user profile for an audience specific message. When the user profile sufficiently matches the desired user profile of the message, the audience specific message is added to a list of custom messages for the user.

摘要： A method for selectable quantization for use in an encoder for compressing video and/or audio data includes processing that begins by receiving discrete cosine transform data of an encoded signal. The processing continues by obtaining a quantization table. The processing then continues by obtaining a plurality of scaling factors. The process then continues by generating a plurality of quantized value sets of the discrete cosine transform data based on the quantization table and the plurality of quantization scaling factors. The resulting data is then multiplied separately by each of the quantization scaling factors to produce the plurality of quantized values sets. The process then continues by selecting one of the plurality of quantized value sets based on quantization selection criteria.

摘要： A multiple device frame synchronization method and apparatus utilizes events completion signaling between multiple devices, such as multiple graphics processors. The signaling serves as a stall command for stalling graphics data rendering commands in a command FIFO of the rendering engine of a graphics processor in response to a rendering complete signal, or other event signal generated by the other graphics processor. Accordingly, the processor that, for example, completes a current frame relay is stalled until the other processor has completed its rendering function for a particular odd line, even line, entire frame or partial frame as desired.
