Description

The CS4952/3 provides full conversion from YCbCr or YUV digital video formats into NTSC & PAL Composite and Y/C (S-video) analog video. Input formats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or CCIR656 with support for EAV/SAV codes. Output video can be formatted to be compatible with NTSC-M, or PAL B,D,G,H,I,M,N, and Combination N systems. Also supported is NTSC line 21 and line 284 closed captioning encoding.
