    摘要: In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.

    摘要: A rasterizer is used with a processor capable of providing raster data indicative of a pattern of pixels to be formed on a display. Each pixel has an attribute represented by a data value. The rasterizer has a replicator connected to form at least two copies of the raster data. A graphics engine is connected to use the at least two copies to store the data values in a memory. An output circuit is connected to use the data values stored in the memory to form the pattern on the display.

    摘要: A method of converting video data from a YUV format to an RGB format comprising (a) performing a matrix transformation of Y, U and V pixel data of a set of possible Y, U and V parameters into corresponding R, G and B parameters, (b) determining whether the set of R, G and B parameters forms a first lookup table whose size exceeds the size of a particular memory space, (c) in the event the lookup table is too large for the memory space, truncating least significant bits of at least the U and V parameters, (d) repeating steps (a), (b) and (c) until the first lookup table fits the memory space, and then storing the first lookup table in the memory space, and (e) using the first lookup table to provide RGB pixel data using the YUV data as addresses thereto.

    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 system and a method for transcoding multiple media channels is disclosed herein. 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 packets, 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 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 generating a plurality of quantization matrixes of discrete cosine transform data based on a quantization table and a plurality of quantization scaling factors. The process continues by analyzing the plurality of quantization matrixes to identify one of the plurality of quantization matrixes having a best match of reduced data content and acceptable video quality. The processing continues by selecting the one of the plurality of quantized matrixes.
