An example apparatus for encoding and decoding video data encodes a first syntax element in a parameter set indicating a luma codec tree block size minus 5 of a codec tree unit (CTU) to which the parameter set is applicable. The device encodes a second syntax element in the parameter set indicating a minimum luma codec block size minus 2 of a luma codec block to which the parameter set applies, where a value of the second syntax element is in a range from 0 to a value based on the first syntax element, including an end value. The device encodes the luma codec block to which the parameter set is applicable according to the first syntax element and the second syntax element in the parameter set. 一种用于对视频数据进行编解码的示例设备对参数集中指示该参数集适用的编解码树单元(CTU)的亮度编解码树块大小减5的第一语法元素进行编解码。该设备对该参数集中指示该参数集适用的亮度编解码块的最小亮度编解码块大小减2的第二语法元素进行编解码，其中，第二语法元素的值在0到基于第一语法元素的值的范围内，含端值。该设备根据该参数集中的第一语法元素和第二语法元素来对该参数集适用的亮度编解码块进行编解码。
