Bt864A/865A
YCrCb to NTSC/PAL Digital Video Encoder
The Bt864A/865A is specifically designed for video systems requiring the generation 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 generated. 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 provide 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.
