Deblocking filter parameter signaling

A video encoder may signal a set of values for one or more deblocking filter parameters at an advanced parameter set. A video decoder may receive and decode a set of values. The video encoder may also encode an index of the set of values at a lower level. The video decoder may decode the index and then use the index to determine a particular value from the set of values to determine a deblocking filter parameter. 视频编码器可以在高级参数集发信令通知用于一个或多个去块滤波器参数的值集合。视频解码器可以接收并解码值集合。视频编码器还可以在较低级别对值集合的索引进行编码。视频解码器可以对该索引进行解码并且然后使用该索引根据该值集合确定特定值以确定去块滤波器参数。
