I have been using the following document to access the RenderingControl Service of a samsung smart TV. So far I can get the volume of the master channel and change it. I am using Cling to do it.

But I have a task ahead to change TV channel and I dont see any action in the document that enables me to do this.
Can someone guide me on how to proceed on this?
Moreover I have tested Smart Remote App on TV and it can successfully changes channels.
