The Advanced Display Stream Compression (ADSC) codec project is in development in response to a call for technologies from the Video Electronics Standards Association (VESA). This codec targets visually lossless compression of display streams at a high compression rate (typically 6 bits/pixel) for mobile/VR/HDR applications. Functionality of the ADSC codec is described in this paper, and subjective trials results are provided using the ISO 29170-2 testing protocol.
This paper presents a distributed coding scheme for the representation of 3D scenes captured by stereo omni-directional
cameras. We consider a scenario where images captured from two different viewpoints are encoded
independently, with a balanced rate distribution among the different cameras. The distributed coding is built on
multiresolution representation and partitioning of the visual information in each camera. The encoder transmits
one partition after entropy coding, as well as the syndrome bits resulting from the channel encoding of the
other partition. The decoder exploits the intra-view correlation and attempts to reconstruct the source image
by combination of the entropy-coded partition and the syndrome information. At the same time, it exploits the
inter-view correlation using motion estimation between images from different cameras. Experiments demonstrate
that the distributed coding solution performs better than a scheme where images are handled independently,
and that the coding rate stays balanced between encoders.
