Product Number: ADV7282A
Hi Sir .
We use the ADV7282A video decoder in our product. The system architecture and signal flow are shown below
RF Tuner ---> CVBS ---> ADV7282A ---> TTL to TMDS (Bridge IC) ---> HDMI receiver of Scaler .
Our Monitor shall continue to display with low or distorted CVBS signal as illustration below
As signal degrades, static is acceptable, but the monitor should not blank to a blue/black screen
Therefore, we must configure the ADV7282A in free-run mode without a test pattern; otherwise, the bridge IC and scaler will be lock lost ,
eventually leading to a black screen . We used the ADV7842 for a different product that support this features ("If in free run output decoded video data") as illustration below
Can the ADV7282A support this, or is there an alternative way to achieve our requirement? Or are there other alternative video decoders we could adopt?
