[iPlex encoder] Audio & video does not sync after switching channel

My company (Viettel, Viet Nam) uses Tandberg iPlex encoders for both IPTV and MobileTV service.

In encoder's configuration, parameter Mode = Standard (3.0s). If IPTV user switches to a different channel, in first 3 seconds video and audio are not synchonized with each other (non lipsync), video look like slow-motion picture.

When we changed Mode = Mega Low Delay (0.75s), IPTV users do not see slow-motion in first 3s, lipsync is OK, but video quanlity is degraded and MobileTV lost lipsync. So we must change Mode back to Standard.

How to correctly configure video & audio parameters in the encoder so that IPTV users do not see slow-motion picture and non-lipsync in the first 3s after switching channel ?

Unfortunately you are looking for product from TANDBERG Television”.

Cisco acquired TANDBERG Telecom developing Unified Conference Endpoint and Infrastructure products.

TANDBERG Television is different company, therefore I’d recommend you contact TANDBERG Television directly to clarify your question/request.

Contact information is available from http://www.ericsson.com/ourportfolio/tv_sales_and_support_contacts.
