Abstract
A method, apparatus, and storage medium for processing video data. According to one embodiment, data encoded in a first high level encoding format is partially decoded. The partially decoded data is encoded in accordance with a second high level encoding format.
Claims21
A method for processing video data, the method comprising the steps of:
- (a) providing data encoded in a first high level encoding format that lies hierarchically above a low level format;
- (b) partially decoding the data to provide data encoded in an interim level encoding format that lies hierarchically above the low level format and hierarchically below both the first high level encoding format and a second high level format, wherein the second high level format lies hierarchically above the low level format and is different from the first high level encoding format;
- and
- (c) encoding the partially decoded data in accordance with the second high level encoding format.
An apparatus for processing video data, the apparatus comprising:
- (a) means for providing data encoded in a first high level encoding format that lies hierarchically above a low level format;
- (b) means for partially decoding the data to provide data encoded in an interim level encoding format that lies hierarchically above the low level format and hierarchically below both the first high level encoding format and a second high level format, wherein the second high level format lies hierarchically above the low level format and is different from the first high level encoding format;
- and
- (c) means for encoding the partially decoded data in accordance with the second high level encoding format.
A storage medium having stored thereon a plurality of instructions for processing video data, wherein the plurality of instructions, when executed by a processor, cause the processor to perform the steps of:
- (a) providing data encoded in a first high level encoding format that lies hierarchically above a low level format;
- (b) partially decoding the data to provide data encoded in an interim level encoding format that lies hierarchically above the low level format and hierarchically below both the first high level encoding format and a second high level format, wherein the second high level format lies hierarchically above the low level format and is different from the first high level encoding format;
- and
- (c) encoding the partially decoded data in accordance with the second high level encoding format.
An apparatus for processing video data, comprising:
- (a) a first format partial decoder;
- and
- (b) a second format partial encoder;
- wherein:
- the first format partial decoder partially decodes data encoded in a first high level encoding format to provide data encoded in an interim level encoding format that lies hierarchically above a low level format and hierarchically below both the first high level encoding format and a second high level format, wherein the second high level is different from the first high level encoding format;
- and
- the second format partial encoder encodes the partially decoded data in accordance with the second high level encoding format.
