Whats the advantage to use MPEG-4 ASIC over DSP?
Current most popular DSP cannot provide enough processing power to process MPEG-4 full D1/30 fps encoding algorithm. The video quality processed via DSP cannot compete with that processed by ASIC. Current DSP usually supports up to CIF (360×240) right now, while ASIC can support not only CIF, but also full D1 (720×480).
