ABSTRACT:
A video encoder having multiple channels each capable of producing an independently controlled encoded output. In one embodiment, the video encoder has circuitry common to all of the channels and separate circuitry for each channel. The common circuitry can include a motion compensator, a transformer, and a local decoder. One or more of the separate circuitry can include a quantizer, a scanner, an encoder, and a buffer. Each channel includes quantization feedback, and one channel output is fed back to the local decoder for use in generating reference pictures. The channels are separately controllable for the characteristics of at least one of quantization, scanning, and encoding.
