com ASAHIKASEI [AK8813/14] 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.
FEATURES • NTSC-M, PAL-B,D,G,H,I,M,N encoding.
• Simultaneous composite video signal and S-video signal outputs • ITU-R BT.
