Parallel computing context in video coding

摘要

In one example, a method for coding video data, includes identifying the scan path to scan the validity information relating to the quantized transform coefficients. The method comprising determining a context support near to entropy code the validity information relating to the quantized transform coefficients, the context support vicinity, the method excludes the context support one or more elements in the scan path to. The method also includes that coding the validity information using a modified context support near.
