AK8813/14
NTSC/PAL Digital Video Encoder
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.
