Complete stand-alone Line 21 decoder for
Extended Data Services (XDS); fully compliant
to EIA-608A and EIA-744A for XDS data recov-
ery and violence blocking
Serves as a complete solution for violence block-
ing applications in TV sets and VCRs by pro-
cessing the Content Advisory Program Rating of
an incoming video program and outputting the
PB (Program Blocking) signal as programmed
Provides 2-byte Content Advisory Data Packets,
the blocking status of a program, and the validity
of a program rating in Content Advisory Regis-
ters 1 & 2 for access control of program blocking
operations and display processing of the current
program rating
Supports blocking of 4 existing Content Advi-
sory Program Ratings:
MPAA/TV Parental Guidelines
Canadian English Language
Canadian French Language
No Rating

programs and
Supports a programmable matrix table in the
control registers to regulate program blocking
utilizing a flexible method of implemention for
age- or content-based ratings
Programmable extension time of program block-
ing upon channel change when in blocking mode
Single-bit control to enable and disable program
blocking and easily implement the program
blocking feature
Special read-access modes for reading internal
control registers, Content Advisory 1 and 2, Con-
tent Advisory Rating Select 1 through 6, and
Channel/Program information
Supports up to 32 bytes of writing without
checking the internal
