TBS2603 fault on HDMI input change

Postby jtevlin » Thu Jun 18, 2020 1:14 pm


I use the TBS2603 to stream a H265 encoded RTP Multicast Stream as shown below.

Code: Select All Code
CAM-A------------|                   |-------------TBS2603----H265_RTP_MULTICAST
CAM-B------------|                   |-------------MONITOR

  • HDMI source is provided by 2 headend devices (CAM-A, CAM-B)
  • Both devices output diferent HDMI formats (1xLowResolution, 1 x HighResolution)
  • Only 1 device is active (either CAM-A OR CAM-B)
  • The stream is viewed via VLC on multiple platforms (Linux, Windows, IOS, Android)

Everything works fine until the end user switches between CAM-A and CAM-B, then the following happens:
  • Switching devices takes ~2 seconds (observed on MONITOR)
  • VLC shows an initial image of the new device (also after the ~2 seconds) and then freezes (other viewers just stop or crash)
  • The TBS2603 stops outputting the stream
  • The TBS2603 restarts the stream after >40 seconds (VLC continues with the new stream)

Problem: >40 seconds to restart a stream is far too long
Request: What can I do to get this 40 seconds down to as close to 0 seconds as possible

When the hdmi signal changed it's resolution or other, the box need restart it's input device, and encode device to adapt the new parameters, it need some times.
