Abstract
A method for encoding a video signal includes estimating a space requirement for encoding a tile of a video frame, writing a first value in a first value space of the bitstream, wherein the first value describes a size of a second value space, and defining the second value space in the bitstream, wherein the size of the second value space is based on an estimated space requirement. The method also includes writing encoded content in a content space of the bitstream, determining a size of the content space subsequent to writing encoded content in the content space, and writing a second value in the second value space of the bitstream, wherein the second value describes the size of the content space.
Claims20
A method for encoding a video signal comprising video frames into a bitstream, the method comprising:
- identifying encoded content associated with at least a portion of the video signal;
- writing, to a first space of the bitstream, a first value indicating a number of bits for encoding a length of the encoded content to the bitstream;
- and
- writing, to a second space of the bitstream, a second value indicating the length of the encoded content.
An apparatus for encoding a video signal comprising video frames into a bitstream, the apparatus comprising:
- a memory;
- and
- a processor configured to execute instructions stored in the memory to:
- identify encoded content associated with at least a portion of the video signal;
- write, to a first space of the bitstream, a first value indicating a number of bits for encoding a length of the encoded content to the bitstream;
- and
- write, to a second space of the bitstream, a second value indicating the length of the encoded content.
A method, comprising:
- decoding encoded content from a bitstream including a first value and a second value, the first value indicating a number of bits used for encoding a length of the encoded content to the bitstream, the second value indicating the length of the encoded content.
