Problems solved by technology

Transmission of HD video in IP packets over Ethernet cables has well-known disadvantages
First, the transmission distance is limited to 100 meters
Second, heavy compression leads to loss of image quality
Third, video frames transmitted in IP packets generate long and variable delays, resulting in video loss of timeliness and smooth fluidity
Fourth, the complexity of IP technology leads to high installation, operation and maintenance...

Abstract

The present invention presents the HD video transmission methods in a transform domain. In an aspect of the present invention, at the HD video transmitter the HD video is transformed into the transform domain by a multi-dimensional transform. Through the discrete-time continuous-valued or quasi-continuous-valued modulation, the obtained coefficients in transform domain are preferably carried in parallel in a multiple-access channel in time-domain to the HD video receiver.

Description

[0001] This application refers to provisional patent application 62,005,396 filed with the US Patent Office on May 30, 2014. technical field [0002] The invention relates to video transmission of video monitoring system, television broadcasting system, machine vision system, virtual reality system, augmented reality system and other video systems. Background technique [0003] Video transmission is a fundamental component and function of many systems and applications. In a typical high-definition surveillance system, multiple high-definition cameras are connected to a video recorder through cables. Each camera transmits at least one high-definition video to the video recorder through a connecting cable. The video recorder usually displays the live video from the camera immediately to monitor the live scene in the field of view of the camera, and also records the live video and plays the video. [0004] Historically, video transmission started with analog transmission. Th...
