TLDR
By following exactly the same most-efficient CPU-GPU-screen graphics rendering pipeline from initial graphics primitives to final pixels as that in the traditional computer graphics architecture developed and optimised in the past decades, the architecture has higher graphics and multimedia performance than any other client-server and cloud-mobile computing architectures.Abstract:
This paper presents a three-decoupling-boundary theory and classification for performance analysis of client-server architectures. Based on the analysis, a novel client-server architecture with top graphics performance is proposed. The client is only a display screen plus a few Human-Interface-Devices such as a mouse-keyboard-set or touchscreen with an optional mobile storage. The client is connected to a remote or nearby server cloudlet by a low latency link transferring primarily post-GPU display screen and HID data. By following exactly the same most-efficient CPU-GPU-screen graphics rendering pipeline from initial graphics primitives to final pixels as that in the traditional computer graphics architecture developed and optimised in the past decades, the architecture has higher graphics and multimedia performance than any other client-server and cloud-mobile computing architectures, e.g. VNC, Remote Desktop, VDI, Zero-client, and PCoIP. No read back of frame buffers as virtualised screen is necessary, so no CPU/GPU overhead occurs and display latency is minimised.read more

A Universal String Matching Approach to Screen Content Coding
TL;DR: A universal string matching (USM) approach to screen content coding (SCC) that uses a primary reference buffer and a secondary reference buffer for string matching and includes three modes: general string (GS), constrained string 1 (CS1) mode, and constrained string 2 (CS2) mode.

Pseudo 2D String Matching Technique for High Efficiency Screen Content Coding
TL;DR: This paper proposes a pseudo 2D string matching (P2SM) technique for high efficiency screen content coding (SCC) that uses a primary reference buffer (PRB) and a secondary referencebuffer (SRB) for string matching and string copying.

Compound image compression based on unified LZ and hybrid coding
Shuhui Wang,Tao Lin +1 more
TL;DR: Experimental results show that the proposed unified LZ and hybrid coding (ULHC) method provides higher peak signal-to-noise ratio and better subjective quality than H.264 at the same bitrate, and also achieves much higher compression ratio than gzip without any visual quality loss.

Response time in man-computer conversational transactions
TL;DR: The literature concerning man-computer transactions abounds in controversy about the limits of "system response time" to a user's command or inquiry at a terminal, but two major semantic issues prohibit resolving this controversy.
