Method of direct screen writing for television system distant end

Abstract

A television system far-end off-screen drawing process relates to a process that the television user directly conducts the off-screen drawing in the far end through using a hand-held remote controller, which comprising inputting characters or special symbols, and transmitting the information to the television system which identifies the information and conducts the relative operations, arranging a remote controller which has four software and hardware modules such as laser shot, image capture, signal modulation and light spot location is arranged on the remote controller side, obtaining the coordinate of the light spot relative to the television through capturing the image of the laser which is transmitted by the remote controller on the television screen, and transmitting the coordinate information to the television side with infrared signals, conducting signal reduction and processing for the signals which are modulated through the inner communication transmitting to the intermediate layer of the television system after received by the television to obtain the absolute coordinate information, and drawing the coordinate on the screen through the application layer of the television system.

Description

technical field [0001] The invention relates to a method for a TV user to use a hand-held remote controller to directly write on the screen at a remote end, input characters or specific symbols, and transmit the information to a TV system for identification and corresponding operations. Background technique [0002] The existing TV remote control basically adopts three input modes: [0003] 1. Traditional key input, [0004] 2. Remote control input similar to mouse, [0005] 3. Use the remote control handwriting input of the tablet, [0006] Current existing technical problems or areas to be improved: [0007] 1. The current TV remote controllers are all the same in terms of appearance and input operation, which has caused aesthetic fatigue to users. Can not highlight the characteristics of the product in appearance. [0008] 2. The TV system cannot directly write to the screen, and simple button operations cannot provide a more powerful user interface. [0009] 3. Wat...
