Abstract
A first division unit divides the motion picture into a plurality of segments. A second division unit divides each segment into a plurality of picture groups each including a plurality of frames. The last picture group of each segment includes frames of a fixed predetermined number. An encoder determines timing information of decoding and display of each picture group based on timing information of a head frame of a previous picture group in each segment, and generates encoded data of each segment. The encoded data includes the timing information of each picture group. A connection unit connects the encoded data of the plurality of segments.
Claims18
An apparatus for encoding a motion picture, comprising:
- a first division unit configured to divide the motion picture into a plurality of segments;
- a second division unit configured to divide each segment into a plurality of picture groups each including a plurality of frames, the last picture group of each segment including frames of a fixed predetermined number;
- an encoder configured to determine timing information of decoding and display of each picture group based on timing information of a head frame of a previous picture group in each segment, and to generate encoded data of each segment, the encoded data including the timing information of each picture group;
- and
- a connection unit configured to connect the encoded data of the plurality of segments.
A method for encoding a motion picture, comprising:
- dividing the motion picture into a plurality of segments;
- dividing each segment into a plurality of picture groups each including a plurality of frames, the last picture group of each segment including frames of a fixed predetermined number;
- determining timing information of decoding and display of each picture group based on timing information of a head frame of a previous picture group in each segment;
- generating encoded data of each segment, the encoded data including the timing information of each picture group;
- and
- connecting the encoded data of the plurality of segments.
A computer readable medium storing program codes for causing a computer to encode a motion picture, the program codes comprising:
- a first program code to divide the motion picture into a plurality of segments;
- a second program code to divide each segment into a plurality of picture groups each including a plurality of frames, the last picture group of each segment including frames of a fixed predetermined number;
- a third program code to determine timing information of decoding and display of each picture group based on timing information of a head frame of a previous picture group in each segment;
