摘要： 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.

摘要： A system and a method for transcoding multiple media channels are provided. The system includes a first processor to parse a media data stream having one or more media data channels and a vector processor to decompress, scale, and then compress the parsed media channel. A parsed media data channel, in one embodiment, is accessed using a bit manipulator and packetized into decoder instruction packets and transmitted to the vector processor using a sequencer. The vector processor decompresses the decoder instruction pacets, scales a macroblock generated from the packets, and then compresses the scaled macroblock. As a result, the scaled and compressed output has less data associated with the media channel, allowing for faster and/or more efficient storage or transmission. A reduced sized scale buffer is associated with another disclosed embodiment.

摘要： A method and apparatus for controlling the amount of quantization processing used within an encoder that compresses video and/or audio data include processing that begins by receiving discrete cosine transform data of a block of a frame of data. The process then proceeds by obtaining a quantization table related to the frame of data. The processing then continues by obtaining a quantization scaling factor related to the frame. The processing then continues by determining whether quantization processing limits have been exceeded for quantization of preceding blocks of the frame of data. If the number of bits processed for the preceding blocks exceeds a certain desired level, the processing increases the quantization scaling factor. The processing then continues by generating quantization data from the discrete cosine transform data, the quantization table and the increased quantization scaling factor.

摘要： A method for a client module to provide a channel selection request in a multimedia system begins by receiving an input signal from a client. The method continues by interpreting the input signal to determine type of signal. The method continues, when the type of signal is control information, by determining whether the control information relates to a local command or a system-level command. The method continues, when the control information relates to a system-level command, by processing the control information for conveyance to a multimedia server to produce a control message. The method continues by transmitting the control message to the multimedia server.

摘要： A graphics display command list handler and method requests allocation of memory, such as system memory, in the form of a circular FIFO which stores the display command list as a memory display list (MDL), such as a host memory display list. A processor, such as a graphics processor, communicates a host memory display list read pointer to the host processor to facilitate display list signaling by the graphics processor. The host processor (or other processor) maintains a write pointer which points to a last host memory entry in the display list. The read pointer is maintained by the graphics processor and written back to the host processor.

摘要： A method and apparatus for improved double buffering within a computing system begins when a series of data blocks are received from a central processing unit at a rate independent of a processing rate of a recipient engine. For example, a video graphics circuit receives a series of data blocks representing video frames from the central processing unit at a rate independent of the refresh rate of the display. As the data blocks are received, the video graphics circuit queues commands of the data blocks. Typically, the commands include processing commands and a processing rate synchronize command. To process the data blocks, the co-processor pulls commands from the queued list and processes them to produce recipient data. As the co-processor is producing the recipient data, it is utilizing a first buffer. The co-processor continues to process the commands and storing the results into the first buffer until the processing rate synchronize command is detected. At this point, the co-processor pauses processing of the commands. At the beginning of the next cycle of the processing rate, the recipient data is provided from the first buffer to the recipient engine and the co-processor resumes processing of commands, which relate to another data block. As the co-processor is processing the commands of the second data block, it is utilizing a second buffer to store the processed data, i.e., the second recipient data.

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.
