GENERAL DESCRIPTION

The AK8813/14 is low voltage, low power and small packaged Digital Video Encoder. It is suitable for a STB or Digital TV. It converts ITU-R.BT601/656 standard 8- bit parallel data into analog composite video signal, S-video in NTSC and PAL formats. AK8813/14 supports Copy protection, Closed Captioning and Video Blanking ID(CGMS-A) and WSS. These functions are controlled by high-speed I2C Bus interface.
