1Productivity
If conventional video coding techniques are used, then the video can be encoded and decoded, but the coding efficiency is low
Solution Approach 1:
The patent performs preliminary actions by determining multiple co-located frames from reference frames before the actual conversion process. These pre-determined frames are stored and prepared in advance, allowing the encoder to efficiently access temporal motion information from multiple time points without repeated computations during the conversion stage, thereby improving coding efficiency while fully utilizing temporal motion information.
2Productivity
If multiple co-located frames are determined and used for conversion, then temporal motion information can be utilized to improve coding efficiency, but the computational complexity and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-determining and storing multiple co-located frames from reference frames before the actual video block conversion. This advance preparation organizes the temporal motion information in a ready-to-use format, reducing the computational burden during the actual encoding process while maintaining high coding efficiency through effective utilization of multiple reference frames.
