PCR Accuracy Error in MPEG TS

Question

What is PCR Accuracy Error?

I am developing application which extracts particular programs from TS, muxes them, makes stream CBR and transmits them.

To make stream CBR, I am inserting NULL packets in output TS.

But on analyser I get errors like PCR-Accuracy_error. What can cause this error.

I think my logic add NULLs to make CBR is perfect. You can see this in attached picture.

Please help me on this.

Answer 1

Are you using PID 0x1FFF for the null packets? Or are you creating video packets with empty payloads? I could see this problem occurring if you are creating video packets with no payload.

Answer 2

Why don't you do this? When you meet a packet you don't want, replace it with NULL pkt.

If you have done so and still see pcr accuracy error, which means the input stream is not CBR either.
