Bt864A/865A

YCrCb to NTSC/PAL Digital Video Encoder

The Bt864A/865A is speciﬁcally designed for video systems requiring the gen-

eration of composite, Y/C (S-video) or RGB (SCART) video signals from an 8-

or 16-bit YCrCb digital video stream. Worldwide video standards are supported

including NTSC-M (N. America, Taiwan, Japan), PAL-B,D,G,H,I (Europe,

Asia), PAL–M (Brazil), PAL-N (Uruguay, Paraguay) and PAL–Nc (Argentina).

The Bt864A and Bt865A are functionally identical, with the exception that

Bt865A can output the Macrovision level 7 anticopy algorithm.

Horizontal sync (HSYNC*) and vertical sync (VSYNC*) may be conﬁgured

as inputs (slave mode) or outputs (master mode). BLANK* is an input and may

be externally controlled. Horizontal and vertical blanking are automatically gen-

erated. The rise and fall times of sync, the burst envelope, and closed caption

data are internally controlled.

Analog luminance (Y) and chrominance (C) information is available on the Y

and C outputs for interfacing to S-video equipment. The composite analog video

signal is output simultaneously onto two outputs. This allows one output to pro-

vide baseband composite video while the other drives an RF modulator. Analog

RGB is also available to allow for support of the European SCART/PeriTV

interface.
