How does the ADV202 recover from data input loss in encode or decode mode?

In particular applications it can not be avoided that a loss of source input does occur.

If the ADV202 is in encode mode and the source is lost during a field, the present data will be flushed out of memory and the ADV202 will wait until the next valid field is input. Reloading the firmware is not necessary.

If data is input on the VDATA on the clock input on VCLK is lost, then encode will stop until a valid clock input is available again.

In decode mode, once data is lost and the ADV202 can not see a valid header input, it will output black fields until it detect a valid header again and continues decoding valid data.

If data is lost during a field, the information will be flushed from memory and the ADV202 waits for the next valid header while outputting black fields.
