Abstract
A method for encoding a visual object, includes encoding a visual object to obtain compressed coded data, wherein the compressed coded data is obtained through at least one of a plurality of different operations which can be performed on a block by block basis. A descriptor capable of including information of a respective parameter related to the number of times that each of the operations was performed in a unit of blocks is generated, the descriptor associated with a complexity of decoding the compressed coded data. The descriptor is multiplexed with the compressed coded data, wherein the descriptor comprises an identification number identifying a descriptor type, a length field indicating a size of the descriptor, and the parameter.
Claims2
A method for encoding a visual object, comprising:
- encoding a visual object to obtain compressed coded data, wherein the compressed coded data is obtained through at least one of a plurality of different operations which can be performed on a block by block basis;
- generating a descriptor capable of including information of a respective parameter related to the number of times that each of said operations was performed in a unit of blocks, said descriptor associated with a complexity of decoding the compressed coded data;
- and
- multiplexing the descriptor with the compressed coded data wherein the descriptor comprises;
- an identification number identifying a descriptor type;
- a length field indicating a size of the descriptor;
- and
- the parameter.
A method for encoding a visual object having a plurality of pictures, comprising:
- encoding a visual object to obtain compressed coded data, wherein the compressed coded data is obtained through segmenting each picture in a plurality of blocks and through performing at least one of a plurality of different operations on a block by block basis;
- generating a descriptor including a parameter related to the number of times that each of said operations was performed during encoding said picture, said descriptor associated with a complexity of decoding the compressed coded data;
- and
- multiplexing the descriptor with the compressed coded data wherein the descriptor comprises;
- an identification number identifying a descriptor type;
- a length field indicating a size of the descriptor;
- and
- the parameter.
