Method and Apparatus for Signaling Layer Information of Scalable Media Data

A method, comprising:

• receiving data in at least one physical layer pipe;
• receiving information related to a mapping of one or more layers of a scalable media stream to the at least one physical layer pipe;
• and
• identifying the one or more layers of the scalable media stream in the received data based on the received information related to the mapping.

An apparatus, comprising:

• a receiver configured to receive data in at least one physical layer pipe;
• wherein the receiver is further configured to receive information related to a mapping of one or more layers of a scalable media stream to the at least one physical layer pipe;
• and
• a controller configured to identify the one or more layers of the scalable media stream in the received data based on the received information related to the mapping.

A computer program product comprising a computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:

• code for mapping one or more layers of a scalable media stream to at least one physical layer pipe of a transmission;
• code for transmitting information related to the mapping;
• and
• code for transmitting the one or more layers in the at least one physical layer pipe.
