Our system has a PAL/NTSC camera as the front end interface. The video from camera is digitised by ADV7183A and fed to BF609 which will do H.264 encoding. What are peripheral devices required for BF609 for doing H.264 encoding for SD resolution @25/30fps. I understand that dRAM is required is storing the reference frames. What are other devices to be connected to BF609. What is the size of DRAM.
