The Core Subsystems include: DSP/CPU - The DSP performs digital A/V processing in all standard media formats. The CPU executes operating-system software and controls data tranfer and user interface. Digital Video Input - comes from the analog video decoder or the CMOS/CCD camera. The analog video decoder converts the NTSC/PAL/S-Video analog input to raw digital video. Stereo Audio Codec - converts the analog audio input from microphone, FM receiver, and and stereo audio line source into digital audio. CCIR656 Bus - to input the raw digital video to the DSP.
