AI Technical Summary
Technical Problem
Existing video codec technologies suffer from high signaling overhead when sending signaling notifications for deblocking filter parameters, which affects the quality and adaptability of deblocking filtering.
Method used
Signaling is sent at the high-level parameter set to notify the set of values for the deblocking filter parameters, and specific values are determined at a lower level using indexes to reduce signaling overhead while maintaining the adaptability of the deblocking filter.
Benefits of technology
By reducing signaling overhead, the quality and adaptability of deblocking filtering are improved, and the data transmission requirements of the encoding process are reduced.

Abstract
A video encoder can signal a set of values for one or more deblocking filter parameters in a high-level parameter set. A video decoder can receive and decode the set of values. The video encoder can also encode an index to the set of values at a lower level. The video decoder can decode the index and then use the index to determine a particular value from the set of values to determine the deblocking filter parameters.
