“…VR applications require low-latency and low-complexity coding that can reduce the bandwidth of frames sent from a GPU to a display. Such requirements are addressed in the recent JPEG XS standard (ISO/IEC 21122) [9]. In Section 7.1 we demonstrate how the efficiency of JPEG XS can be further improved when combined with the proposed method.…”

“…In order to investigate the potential for additional bandwidth savings, we tested our method in conjunction with one of the latest compression protocols designed for real-time applications -the JPEG XS standard (ISO/IEC 21122). The JPEG XS standard defines a low-complexity and low-latency compression algorithm for applications where (due to the latency requirements) it was common to use uncompressed image data [9]. As JPEG XS offers various degrees of parallelism, it can be efficiently implemented on a multitude of CPUs, GPUs and FPGAs.…”

Rendered frames GPU / Rendering Perceived stimulus Decoding & display Transmission Figure 1: Our technique renders every second frame at a lower resolution to save on rendering time and data transmission bandwidth. Before the frames are displayed, the low resolution frames are upsampled and high-resolution frames are compensated for the lost information. When such a sequence is viewed at a high frame rate, the frames are perceived as though they were rendered at full resolution.

“…So maintaining a high data rate across the interfaces requires more power, more wires, and more shielding to prevent electromagnetic interference 1 . These requirements increase device weight, hardware cost, and complexity and are sometimes economically infeasible with current technology 2 . Bandwidth can be greatly reduced using existing algorithms such as H.264 Intra‐only, Motion JPEG 2000, 3 and Dirac/VC‐2, 4 but these algorithms cannot provide visually lossless quality with modest hardware complexity, in real time, and with the low latency expected of a display link 1 .…”

Subjective assessment of display stream compression for stereoscopic imagery

High‐resolution display bandwidth requirements often now exceed the capacity of display link channels necessitating compression. The goal of visually lossless compression codecs such as VESA DSC 1.2 is that viewers perceive no difference between the compressed and uncompressed images, maintaining long‐standing expectations of a lossless display link. Such low impairment performance is difficult to validate as artifacts are at or below sensory threshold. We have developed a 3D version of the ISO/IEC 29170‐2 flicker paradigm and used it to compare the effects of image compression in flat images presented in the plane of the screen (2D) to compression in flat images with a disparity offset from the screen (3D). We hypothesized that differences in the location and size of the compression errors between the disparate images in the 3D case would affect their visibility. The results showed that artifacts were often less visible in 3D compared to 2D viewing. These findings have practical applications with respect to codec performance targets and algorithm development for 3D movie, animation, and virtual reality content. In particular, higher compression should be attainable in stereoscopic compared to equivalent 2D images because of increased tolerance to artifacts that are binocularly unmatched or have disparity relative to the screen.

In March 2016 the Joint Photographic Experts Group (JPEG), formally known as ISO/IEC SC29 WG1, issued a call for proposals soliciting compression technologies for a low-latency, lightweight and visually transparent video compression scheme. Within the JPEG family of standards, this scheme was denominated JPEG XS. The subjective evaluation of visually lossless compressed video sequences at high resolutions and bit depths poses particular challenges. This paper describes the adopted procedures, the subjective evaluation setup, the evaluation process and summarizes the obtained results which were achieved in the context of the JPEG XS standardization process.
