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
additional data channels, two Captions, two Text and
Extended Data Services (XDS). XDS data structure is
defined in EIA-608. The Z86129 can recover and display
data transmitted on any of these nine data channels. The
Z86130 and Z86131 are derivatives of the Z86129 which
can recover XDS data and output the recovered data via
the serial port. The Z86130 and Z86131 do not have OSD
capability, but are ideally suited for Line 21 data slicer
applications.
The Z86129/130/131 can recover and output to a host
processor via the I2C 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 implementing NTSC Violence Block. The
Z86131 is designed especially for extracting XDS time
information for Automatic 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.
