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 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.
