AI Technical Summary
In existing video decoding technologies, high-level syntax elements are not sufficiently constrained, causing the decoder to need to parse unnecessary information, increasing decoding complexity and power consumption. At the same time, it cannot effectively identify the appropriate bitstream, especially in multi-candidate environments.
By introducing General Constraint Information (GCI) tags, the video encoder encodes syntax elements to constrain other syntax elements, such as specifying whether sub-picture information exists or whether a list of reference pictures exists. The video decoder decodes based on these tags and modifies the semantics of existing GCI tags to further constrain higher-level syntax elements.
It reduces the complexity and power consumption of video decoding, improves adaptability to receivers, can identify and discard unsupported decoding features, reduces unnecessary parsing, and improves video encoding efficiency.
