H.239 issue and problem

Unanswered Question
May 27th, 2010


I have a problem when I use data share in a videoconference. After I have started the H.239 media stream, the content takes a minute to appear and each time I show a new screen, I need a lot of time (until one minute) until the image is reconstructed.

I don´t have any quality issue with the video stream, only with the data stream. Can anyone say me what can be the problem?. A jitter or delay problem would also affect the video quality, but can be the problem?

What can I do to improve the h.239 stream quality?

Best Regards,


I have this problem too.

Antonio, the frame rate setting for the content portion of H.239 stream may need to be adjusted. If the rate is too low, it takes longer to change what is displayed. If it is set too high, that is higher than the available TCP network bandwidth between the MCU and viewers' system then you could have degradation due to lost data.

Of course bandwidth is part of the equation.
