Beta offset control for deblocking filters in video coding

A method of encoding video data, the method comprising:

• encoding a beta offset parameter (“beta_offset”) that controls a deblocking filter for a video block;
• identifying a beta parameter (“β”) value used to determine a threshold value of at least one deblocking decision for the deblocking filter;
• and
• calculating the deblocking decision for the deblocking filter according to a modified threshold value, wherein the threshold value is modified based on a multiplier value of the beta offset parameter that causes an integer change in the modified threshold value.

A video coding device comprising:

• means for coding a beta offset parameter (“beta_offset”) that controls a deblocking filter for a video block;
• means for identifying a beta parameter (“β”) value used to determine a threshold value of at least one deblocking decision for the deblocking filter;
• and
• means for calculating the deblocking decision for the deblocking filter according to the threshold value modified based on a multiplier value of the beta offset parameter that causes an integer change in the modified threshold value.

A computer readable medium comprising instructions for coding video data that when executed cause one or more processors to:

• code a beta offset parameter (“beta_offset”) that controls a deblocking filter for a video block;
• identify a beta parameter (“β”) value used to determine a threshold value of at least one deblocking decision for the deblocking filter;
• and
• calculate the deblocking decision for the deblocking filter according to the threshold value modified based on a multiplier value of the beta offset parameter that causes an integer change in the modified threshold value.
