Abstract
A system and method for providing improved FGS identification in scalable video coding. According to the present invention, each FGS enhancement layer is assigned a unique dependency identifier and contains only FGS enhancement information. For subsequent enhancement layers, the base dependency identifier for the subsequent enhancement layers will point to either a base-quality layer or an FGS enhancement layer.
Claims15
A method of decoding scalable video data possessing multiple layers, comprising:
- providing a base quality layer;
- and
- providing at least one fine grain scalability enhancement layer, each of the at least one FGS enhancement layer being coded directly or indirectly relative to the base quality layer,
- wherein the at least one fine grain scalability enhancement layer includes only fine grain scalability enhancement information and is associated with an identifier that is drawn from a predetermined sequence of numbers used to identify all enhancement layers and the base quality layer and is different from identifiers of the base quality layer and other fine grain scalability enhancement layers.
A computer program product for decoding scalable video data possessing multiple layers, comprising:
- computer code for providing a base quality layer;
- and
- computer code for providing at least one fine grain scalability enhancement layer, each of the at least one fine grain scalability enhancement layer being coded directly or indirectly relative to the base-quality layer,
- wherein the at least one fine grain scalability enhancement layer includes only fine grain scalability enhancement information and is associated with an identifier that is drawn from a predetermined sequence of identifiers used to identify all enhancement layers and the base quality layer and is different from identifiers of the base quality layer and other fine grain scalability enhancement layers.
An electronic device, comprising:
- a processor;
- and
- a memory unit operatively connected to the processor and including a computer program product for decoding scalable video data possessing multiple layers, including:
- computer code for providing a base quality layer, and
- computer code for providing at least one fine grain scalability enhancement layer, each of the at least one fine grain scalability enhancement layer being coded directly or indirectly relative to the base-quality layer,
- wherein the at least one fine grain scalability enhancement layer includes only fine grain scalability enhancement information and is associated with an identifier that is drawn from a predetermined sequence of identifiers used to identify all enhancement layers and the base quality layer and is different from identifiers of the base quality layer and other fine grain scalability enhancement layers.
