4. Functional Description
RTD2523/2513
4.1 Input
Digital Input (ITU 656)
RTD is designed to connect the interface of digital signal from video decoder. Input data is latched
within a capture window defined in registers. The timing scheme designed for input devices are
showed in the following diagram.
There are not H sync、V sync signals provided by the video decoder with ITU BT.656, these
synchronal signals have to be generated by decoding the EAV & SAV timing reference signals.

Only 254 of possible 256 8-bit words may be used to express a signal value, 0 and 255 are reserved for
data identification purposes. Video 8 data stream is as below:

Vertical blanking bit V=1 H=0 in SAV Protection bits
Active video V=0
H=1 in EAV
Hardware can recognize the occurrence of EAV & SAV by detecting the 0xff , 0x00 , 0x00 data
sequence, and then generate the Hsync、Vsync、Field signals internally by decoding the fourth word
of the timing reference signal(EAV、SAV). F & V change state synchronously with the EAV(End of
active video) reference code at the beginning of the digital line.
Bits P0, P1, P2, P3, have states dependent on the states of the bits F, V and H as shown below. At the
receiver this permits one-bit errors to be corrected and two-bits errors to be detected.
