A Protocol Primer Introduction This is a primer for people who want a quick understanding of without having to comb through the tedious details of a complex specification. Overview of DAB How. When the data is closed caption management data, 00h stv-b37 is used to fill the display timing value or the timing correction value is made to be zero, and immediate transmission is implemented.
Note that in cases where closed caption PES data are divided into packets during TS packetization, the CRC which is appended to the final 2 bytes of the closed caption data group should not be divided into 2 different packets. CRC added when Group A is used for closedcaption text page management data.
Data identification word for ancillary data. Timing correction values are indicated when the timing type is relative time.
Time code parameters which determine the display timing control for closed caption data. The names Closed caption srd-b37 data 1, Closed caption ancillary data 2, and Closed caption ancillary data 3 are applied in sequence from the leading ancillary data packet. The code structure is known ascompressed differential cyclic coding, which can correct all errors of 8 bits or less. SIN Issue 2. Well, this topic is More information.

This specific standard is applicable to the structure and operation of closed caption conveyed in the form of ancillary data packets. In accordance with its length, the data is sent as a single wordunit closed caption data word or separated into multiple units before transmission. John West, extjwest informationactive.
