GENERAL DESCRIPTION
The Z86129/130/131 is a stand-alone integrated circuit,
capable of processing Vertical Blanking Interval (VBI) data
from both fields of the video frame in data conforming to
the transmission format defined in the Television Decoder
Circuits Act of 1990 and in accordance with the Electronics
Industry Association specification 608 (EIA-608).
The Line 21 data stream can consist of data from several
data channels multiplexed together. Field 1 has four data
channels, two Captions and two Text. Field 2 has five ad-
ditional data channels, two Captions, two Text and Extend-
ed Data Services (XDS). XDS data structure is defined in
EIA-608. The Z86129 can recover and display data trans-
mitted on any of these nine data channels. The Z86130
and Z86131 are derivatives of the Z86129 which can re-
cover XDS data and output the recovered data via the se-
rial port. The Z86130 and Z86131 do not have OSD capa-
bility, but are ideally suited for Line 21 data slicer
applications.
The Z86129/130/131 can recover and output to a host pro-
cessor via the I
C serial bus any XDS data packet defined
in EIA-608. On-chip XDS filters are fully programmable,
enabling recovery of only those XDS data packets selected
by the user, making the Z86129/130 an ideal choice for im-
plementing NTSC Violence Block. The Z86131 is designed
especially for extracting XDS time information for Automat-
ic Clock-Set features in TVs, VCRs, and Set-Top boxes.

In addition, the Z86129/130 is ideally suited to monitor Line
21 of video displayed in a PiP window for violence blocking
purposes. A block diagram of the Z86129/130/131 is
shown in Figure 1.
