I am trying to get an mpeg background video to play in the OpenCable Simulator Frame but so far it has not worked. I am setting the video file name in Channel Properties dialog:

CHANNEL #:1
SOURCE ID:1
NETWORK ID:1
PROGRAM #:1
FREQUENCY: 63000
MODULATION_FORMAT: QAM_64
CHANNLE TYPE:NORMAL
SYMBOL RATE: 1280000
CODING MODE:RATE_5_SLASH_11_CODING
BACKGROUND VIDEO:
-----select background video file (checked)
LOOP BACKGROUND VIDEO: checked

Any help is appreciated.

There could be more than one problem here.

First, have you specified the background video file to be the transport stream you are attempting to configure?

Second, is your MPEG file a true transport stream?

Third, make sure the channel map entries match the content of your transport stream.

Fourth, when you create your OCAP Simulation launch configuration you need to specify the new channel map you created for the transport stream. This is done in the "Bound Services" tab of the launch configuration UI. By default the launch configuration is using default_channel_map_configuration.

Thank you for your response, Much appreciated.

Indeed, my transport stream was not correct. In such a case, it played in simulator, but in separate window outside of simulator frame.

Also, it required a combination of setting the mpeg file in run configuration -> bound services, and channel maps at 'use default background video'. It is unclear what video is acutally supported. The spec. says Video should have a resolution of 720x576 at 25 frames per second (for MHP) or 640x480 at 30 frames per second (for OCAP) but in the sample we were able to play a 640 X 480 video encoded at 30 frames per second.

We are getting there with trial and error. Thanks for your help.
