word length = 204 bytes, sync word length = 8 bits, K = 0, L = 2,
60 Mbits/s):
For an expected BER of 1.0e - 03, the decoder requires about four frame
times to establish synchronization, and loss of sync occurs after
9.0e + 15 frames. With one modification, the DVB Standard of the Euro-
pean Broadcast Union has adopted this basic format as a standard for
multiprogram TV via satellite. One out of every eight synchronization
words in the data stream is mod 2 complemented.
data format of the L64704 transport packet.
Given a bit stream that consists of a sequence of these packets, the
second synchronization stage searches for the predefined sync byte and,
upon having met the synchronization acquisition criteria, issues the
control strobes for the modules that follow.
