Introduction

The Z86230 is a stand-alone integrated circuit, capable of processing Extended Data Services (XDS) in Field 2 of the Vertical Blanking Interval (VBI) of a video frame. This device conforms to the transmission format defined in the Television Decoder Circuits Act of 1990, in accordance with the Electronics Industry Association specification EIA-608A and EIA-744A. The XDS data is processed to provide either a Program Blocking signal (PB) or a recovered XDS data packet. The PB matches the contents of the recovered Content Advisory packet to the user selections input on the decoder. On-chip XDS filters in the Z86230 are fully-programmable, enabling recovery of only those XDS data packets selected for use in TVs, VCRs, and Set-Top boxes. In addition, the Z86230 is ideally suited to monitor Picture-In-Picture (PiP) window video for violence blocking and other XDS data services.

Features

• A stand-alone Line 21 Decoder for Extended Data Services (XDS).
• Extractable XDS data from the input video.
• Full output of a selectable V-Chip Program Blocking signal (PB).
• Selectable XDS filter parameters from a list of preprogrammed values.
• Minimal communications and control overhead that provides simple implementation of Violence Blocking and Auto Clock Set Features.
• Full output of the recovered XDS data through the I²C serial communication port.
• Two different slave addresses that are selectable in the I²C serial communication port.
• Selectable NTSC or PAL operation.
