I have some questions about time (Latency) from input to output of Video for ADV7482.
My customer uses ADV7482 for their project.
He will use ADV7482 for CVBS input, Component (YPbPr) input, S-Video (Y/C) input and HDMI input.
He wants to know the time (Latency) from input to output of Video for developing their software.
About CVBS input, I think the latency depends on the script.
I see following thread.
In fast-switch-script, it says "Fast switch mode allows the ADV7182/728x video decoders to lock to single-ended CVBS or differential CVBS video in under 250 ms."
In normal-script, I think it may takes more than 1 second (typical 1 second) from CVBS input to output.
So I will answer the times ("Max 250ms in fast-switch-script" and "Typ 1 second in normal-script") to the customer.
If it has any problem, please let me know.
There are no fast-switch-script for Component (YPbPr) input, S-Video (Y/C) input.
In this case, I think it may takes "typical 1 second" from Component or S-Video input to output.
Is this right?
There is a thread in case of HDMI input as follows:
You said " I beleive, Customers can use 100ms and then we have plenty of time to achieve the lock by assuming a good video input. In our software also we are using the100ms polling."
So I think it may takes "typical 100ms" from HDMI input to output.
Is this right?
Is it OK that I answer "typical 1 second from Component or S-Video input to output" and "typical 100ms from HDMI input to output" to the customer?
If you have any other time (Latency) from input to output, could you tell me it?
If possible, we want to know the maximum time. But if you don't have the maximum time, typical time is OK.
