Method and system for converting a 3D video with targeted advertisement into a 2D video for display

A system for performing video coding, the system comprising:

• a demultiplexer to receive a compound transport stream, the compound transport stream comprising 3D program video streams, the compound transport stream further comprising scene graph advertising streams, the demultiplexer further to extract targeted scene graph advertising streams from the scene graph advertising streams based on user criteria;
• a decoder to decode the 3D program video streams;
• a graphics processor to process the targeted scene graph advertising streams to generate targeted advertising graphic objects;
• the graphics processor further operable to extract scene graph information from the received compound transport stream, the scene graph information comprising a 3D scene graph of the targeted scene graph advertising streams;
• and
• a compositor to splice the targeted advertising graphic objects for the extracted targeted scene graph advertising streams into the decoded 3D program video streams for a 2D presentation at one or more locations indicated in the 3D scene graph of the targeted scene graph advertising streams.
