Abstract
Method, apparatus and computer readable media for receiving a multiprogram program transport service that includes one or more compressed video services and one or more 3D-2D conversion options, generating an uncompressed video signal by performing a decoding portion of a transcoding operation for one of the one or more of the video services, determining from the 3D-2D conversion option whether a 3D-2D conversion is to be performed, performing a scale conversion on the uncompressed video according to a specified type of 3D-2D conversion, generating a compressed video service by performing an encoding portion of a transcoding operation on the uncompressed video that has been scale converted, and generating a second multiprogram program transport service that includes the compressed video signal that has been 3D-2D converted.
