Hi Ross,
Thanks for your input and sorry for the late reply. Infact the problem was related to the client STB's. We have one more clarification. The sequence of testing is as below. We took a clear MPEG2 TS content and encrypted it using Verimatrix Encryption Manager ( DRM ). Copied the encrypted content in the Live555 Media Server. Then we played the encrypted content using STB with a Verimatrix Client software in it. The contents were decrypted and playing fine from the Live555 Media Server. Step 1: Then we created a .tsx file from the same clear content and used the same file to do the trick play. Now FFW and REW was not working. But normal play was working fine. Step2: Created a .tsx file from the encrypted content. Then we used this .tsx file to do the trick play. Now also FFW and REW was not working. But normal play was working fine. We presume the .tsx file contains only I Frames. Can you please suggest us / help us understand why .tsx file was not supporting Trick mode in both scenarios ( Clear as well as encrypted .tsx file ) even though we have the Verimatrix decryption client available in the client STB.

By this I presume you meant that you used the "testMPEG2TransportStreamTrickPlay" utility to generate Transport Stream files (corresponding to various fast-forward speeds of the original), and played these files locally using VLC. The Transport Stream data in these files are exactly the same as the data that the "LIVE555 Media Server" streams when asked to 'fast-forward' at the same speed. Therefore, the problem must be in either your STB clients, or the network. I suspect that at least part of the problem is that the 'faster' streams are being sent at a higher bitrate (because they consist only of large 'key frames'). Network congestion and/or packet loss may be the cause of some of the problems that you're seeing with your network clients. Ross Finlayson Live Networks, Inc. http://www.live555.com/
