Spatial Layer Rate Allocation - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240314328 titled 'Spatial Layer Rate Allocation
The method described in the abstract involves receiving transform coefficients for a scaled video input signal with multiple spatial layers, including a base layer. The method determines a spatial rate factor based on a sample of frames from the input signal, which helps allocate bit rates at each spatial layer of an encoded bit stream. By reducing distortion for the spatial layers through proper bit rate allocation, the method improves the overall quality of the video.

Original Abstract Submitted
a method includes receiving transform coefficients corresponding to a scaled video input signal, the scaled video input signal including a plurality of spatial layers that include a base layer. the method also includes determining a spatial rate factor based on a sample of frames from the scaled video input signal. the spatial rate factor defines a factor for bit rate allocation at each spatial layer of an encoded bit stream formed from the scaled video input signal. the spatial rate factor is represented by a difference between a rate of bits per transform coefficient of the base layer and an average rate of bits per transform coefficient. the method also includes reducing a distortion for the plurality of spatial layers by allocating a bit rate to each spatial layer based on the spatial rate factor and the sample of frames.
