1.0 Circuit Description
Bt864A/865A
1.11 Anticopy Process (Bt865A Only)
YCrCb to NTSC/PAL Digital Video Encoder
1-30
Conexant
100138B
1.11 Anticopy Process (Bt865A Only)
The anticopy process contained within the Bt865A is implemented according to
the Macrovision version 7 specification developed by Macrovision Corporation in
Sunnyvale, California. All luminance, chrominance, and composite video
waveforms include the Macrovision Anticopy Process. The Bt865A incorporates
an anticopy process technology that is protected by U.S. patents and other
intellectual property rights. The anticopy process is licensed for noncommercial,
home use only. Reverse engineering or disassembly is prohibited.
Conexant cannot ship Bt865A encoders to any customer until that customer
has been licensed by Macrovision. Contact Macrovision Corporation to facilitate
this license agreement. Parties who have obtained a Macrovision license may
receive the Bt865A Macrovision Supplement by contacting Conexant.
1.12 Internal Color Bars
The Bt864A/865A can be configured to internally generate colorbar test patterns
(100/7.5/75/7.5 with SETUPDIS = 0 for NTSC/PAL-M,N; 100/0/75/0 with
SETUPDIS = 1 for NTSC
Japan, PAL, BDGHI, Nc).
Internal color bars can be enabled by setting the ECBAR bit to a logical one.
In 8-bit YCrCb mode, setting the Y[7] pin to a logical one also enables color bars,
thereby simplifying testing of various modes. Internal color bars can be enabled
in all video formats.
