LOOKUP TABLE CODING

摘要

In general, techniques are described for lookup table coding. A device comprising one or more processors and a memory may be configured to perform the techniques. The processors are configured to receive at least one difference table including a set of values, each value of the set being included or not included in the reference lookup table and generate a current lookup table based on the reference lookup table and the difference table. The current lookup table may include at least one of a value from the difference table that is not included in the reference table or a value from the reference table that is not included in the difference table. The one or more processors may then decode the video data based on a set of values of the current lookup table. The memory may be configured to store the current lookup table.

1. A method of decoding video data, the method comprising:
receiving a reference lookup table; receiving at least one difference table including a set of values, each value of the set being included or not included in the reference lookup table; generating a current lookup table based on the reference lookup table and the difference table, wherein the current lookup table includes at least one of a value from the difference table that is not included in the reference table or a value from the reference table that is not included in the difference table; and decoding the video data based on a set of values of the current lookup table.
