In the DVB Broadcast Transmitter side Video Encoder there is a provision for pushing Auxiliary data on RS 232 port.
Generally no body uses it however it can be used to control some of the equipment (e.g. a modulator) on specific remote site.
In one of the project we are required to provide this Auxilary data pushed from encoder at studio on RS 232 port of the STB.
I think Dreambox has rs232 port but it is used only for transferring images.
If any body knows a way by which RS232 port can be controlled to work for Auxiliary data or for Image Transfer then it will help.
Thank in Advance
