Abstract
The present disclosure describes a system and method for multi-layered image and video delivery using reference processing signal. A multi-layered encoder and a multi-layered decoder, both comprising at least one enhancement layer processor that uses reference processing and a base layer processor are provided. A multi-layered encoder and a multi-layered decoder that use reference processing and are capable of frame-compatible 3D video delivery are also described.
Claims7
A decoding method for multi-layered frame-compatible video delivery with one or more processors, the method comprising:
- receiving a coded bitstream comprising a coded base layer, a coded first enhancement layer, and a coded second enhancement layer;
- base layer processing of the coded base layer using a base layer processor to generate at least one frame-compatible base layer decoded image, wherein the at least one frame-compatible base layer decoded image comprises a base layer image of a first view in a first spatial resolution and a base layer image of a second view in the first spatial resolution multiplexed together in a multiplexing pattern;
- a first enhancement layer processing of the coded first layer bitstream to generate a first decoded residual image for the first view at a second spatial resolution higher than the first spatial resolution;
- a second enhancement layer processing of the coded second layer bitstream to generate a second decoded residual image for the second view at the second spatial resolution;
- a first reference processing to generate a first reference image at the second spatial resolution based on a decoded base layer image of the first view and a first filtering method specified in the coded bitstream;
- a second reference processing to generate a second reference image at the second spatial resolution based on a decoded base layer image of the second view and a second filtering method specified in the coded bitstream;
- performing disparity compensation using the first reference image and the first decoded residual image to generate an output first view at the second spatial resolution;
- and
- performing disparity compensation using the second reference image and the second decoded residual image to generate an output second view at the second spatial resolution.
