A METHOD AND DEVICE FOR ENCODING, DECODING, STORAGE AND TRANSMISSION OF A SCALABLE DATA STREAM (402) TO INCLUDE LAYERS HAVING DIFFERENT CODING PROPERTIES. THE METHOD INCLUDES: PRODUCING ONE OR MORE LAYERS OF THE SCALABLE DATA STREAM (402), WHEREIN THE LAYERS ARE CHARACTERIZED BY A CODING PROPERTY, AND SIGNALING THE LAYERS WITH THE CODING PROPERTY SUCH THAT THEY ARE READABLE BY A DECODER TO DETERMINE THE CODING PROPERTY WITHOUT ANALYZING THE SCALABLE DATA STREAM (402). ALSO, A METHOD OF ENCODING, DECODING, STORAGE, AND TRANSMISSION OF A SCALABLE BIT STREAM (100), WHEREIN AT LEAST TWO SCALABILITY LAYERS ARE PRESENT AND EACH LAYER IS CHARACTERIZED BY A SET OF AT LEAST ONE PROPERTY, SUCH AS PROFILE, LEVEL AND A SET OF AT LEAST ONE HRD/VBV PARAMETER, THAT MAY BE DIFFERENT FROM THAT OF THE ENTIRE STREAM, AND WHEREIN SAID A SET OF AT LEAST ONE PROPERTY IS SIGNALED FOR AT LEAST ONE LAYER THAT IS DIFFERENT FROM THE ENTIRE STREAM, WHEREIN SIGNALING OF SAID A SET OF AT LEAST ONE PROPERTY MAY BE IN SAID SCALABLE BIT STREAM (100), IN A FILE FORMAT CONTAINER CONTAINING SAID SCALABLE BIT STREAM (100), OR IN A TRANSMISSION OR CONTROL PROTOCOL FOR TRANSMISSION OR CONTROL OF AT LEAST ONE LAYER OF SAID SCALABLE BIT STREAM (100). |
