A video decoding device includes a metadata extraction device that extracts metadata and a video signal from a processed video signal, wherein the metadata is time-coded in accordance with at least one time stamp of the video signal. A metadata display generator generates metadata display data in response to the metadata. A video decoder decodes the video signal to generate a decoded video signal. An output interface generates a video/metadata output by synchronizing the metadata display data to the decoded video signal in accordance with the at least one time stamp.

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.

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.

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.
