Abstract
A method for encoding pictures within a groups of pictures using prediction, where a first reference picture from a group of pictures and a second reference pictures from the subsequent group of pictures are used in predicting pictures in the group of pictures associated with the first reference picture. A plurality of anchor pictures in the group of pictures associated with the first reference picture may be predicted using both the first and second reference pictures to ensure a smooth transition between different groups of pictures within a video frame.
Claims20
A method for encoding a group of pictures, the method comprising:
- encoding, using a circuit, a first secondary reference picture in the group of pictures utilizing a first primary reference picture and a second primary reference picture, where the first primary reference picture is associated with the group of pictures and the second primary reference picture is associated with a second group of pictures;
- and
- encoding a second secondary reference picture in the group of pictures utilizing an immediately preceding reference picture and the second primary reference picture, where the immediately preceding reference picture comprises one of the first primary reference picture or another secondary reference picture in the group of pictures.
A non-transitory machine-readable storage having stored thereon, a computer program having at least one code section for encoding a group of pictures, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
- encoding a first secondary reference picture in the group of pictures utilizing a first primary reference picture and a second primary reference picture, where the first primary reference picture is associated with the group of pictures and the second primary reference picture is associated with a second group of pictures;
- and
- encoding a second secondary reference picture in the group of pictures utilizing an immediately preceding reference picture and the second primary reference picture, where the immediately preceding reference picture comprises one of the first primary reference picture or another secondary reference picture in the group of pictures.
A system for encoding a group of pictures, the system comprising:
- at least one processor capable of encoding a first secondary reference picture in the group of pictures utilizing a first primary reference picture and a second primary reference picture, where the first primary reference picture is associated with the group of pictures and the second primary reference picture is associated with a second group of pictures;
- and
- the at least one processor capable of encoding a second secondary reference picture in the group of pictures utilizing an immediately preceding reference picture and the second primary reference picture, where the immediately preceding reference picture comprises one of the first primary reference picture or another secondary reference picture in the group of pictures.
