Claim Text:
1. A method of decoding video data, the method comprising: decoding a beta offset parameter (“beta_offset”) that controls a deblocking filter for a video block; identifying a beta parameter (“β”) value used to determine an original threshold value of each of a plurality of deblocking decisions for the deblocking filter; determining a modified threshold value of each of the plurality of deblocking decisions for the deblocking filter based on the beta offset parameter; and calculating each of the plurality of deblocking decisions for the deblocking filter according to the modified threshold value of the respective deblocking decision, wherein the modified threshold value is modified from the original threshold value of the respective deblocking decision based on a multiplier value of the beta offset parameter selected to cause an integer change in the modified threshold value, wherein the multiplier value comprises an integer, and wherein: determining the modified threshold value comprises: determining the modified threshold value comprises:
