C a p a b l e o f p r o c e s s i n g V e r t i c a l B l a n k i n g I n t er v a l ( V B I ) data from both fields of the video frame in data, the Z86229 Line 21 Decoder offers a feature-rich solution for any telev i s i o n o r s e t -t o p a p p l i c at i o n . T h e r o b u s t n a t u re o f t h e Z86229 helps the device conform to the transmission format defined in the Television Decoder Circuits Act of 1990, and i n a c c o r d a n c e w i t h t h e E l e c t r o n i c s In d u s t r y A s s o c i a t i o n specification 608 (EIA608). The Line 21 data stream can consist of data from several data channels multiplexed together. Field 1 consists of four data channels: two Captions and two Texts. Field 2 consists of five additional data channels: two Captions, two Texts, and Extended Data Services (XDS). The XDS data structure is
defined in EIA608. The Z86229 can recover and display data transmitted on any of these nine data channels. The Z86229 can recover and output to a host processor via the I2C serial bus. The recovered XDS data packet is further defined in the EIA608 specification. The on-chip XDS filters in the Z86229 are fully programmable, enabling recovery of only those XDS data packets selected by the user. This functionality allows the device to extract the required X DS information with proper X DS filter setup for compatibility in a variety of TVs, VCRs, and Set-Top boxes. In addition, the Z86229 is ideally suited to monitor Line 21 v i d e o d i s p l a y e d i n a P i P w i n d o w f o r v i o l e n ce b l o c k i n g , CCD, and other XDS data services. A block diagram of the Z86229 is illustrated in Figure 1.
