Digital Video Encoder (EURO-DENC2)
The data demultiplexing phase is coupled to the internal horizontal phase.
The CREF signal applies only for the 16 line digital TV format, because these signals are only valid in 13.5 MHz.
The phase of the RCV2 signal is programmed to tbf (tbf for 50 Hz) in this example in output mode (RCV2S).
(1) Sequence bit:
(2) Reserved bits: 235 with 50 Hz systems; 232 with 60 Hz systems.
(3) Only from SAA7111 decoder.
(4) SAAA7111 provides (22 : 0) bits, resulting in 3 reserved bits before sequence bit.
