Problems solved by technology

[0004] The usual program viewing authority is set by locking the program or the remote control, but the password must be entered every time, and it is usually the same password, which is not only troublesome, but also easy to be cracked, which is not safe
At the same time, it cannot prevent other users from peeking when authorized users watch
It is invalid to set the automatic shutdown for the limitation of viewing period and viewing time. The user can turn it on again, which does not work
None of the current technologies can achieve instant and automatic identification of the user's viewing rights

Embodiment Construction

[0035] The device will be further introduced below in conjunction with the accompanying drawings.

[0036] 1. Invention ideas

[0037] Such as figure 1 Shown is the flow chart of the interaction between the user and the distance information of the digital TV. According to the common sense, if the user is watching a TV program, he usually stays in one position for a while, and if he just walks in front of the TV, he usually does not stay in one position for too long. Therefore, it can be judged whether the user is watching TV based on whether the user's location moves or not and the stay time. Set a time period t to measure whether the user is watching TV. If the user stays in a certain location for more than this time period t, it means that the user is watching TV, otherwise it is just passing by. A database is set up, which stores the characteristic information of the user and the corresponding optimal viewing distance range and the like. Read the height of the user in fr...

Abstract

The apparatus senses and identifies different users by using an infrared scan device so as to remind users of the watching distance. It comprises an infrared scan device, a video camera, a distance and body-height calculating module, a buffer, a matching module, a processor, a controller, a database, a database read-write module and a timing module.

Description

technical field [0001] The present invention relates to a device for controlling the viewing distance and authority of a digital TV, in particular, it relates to a human-computer information interaction technology, that is, different users are sensed and identified by an infrared scanning device, and the user is reminded according to preset parameters Whether the distance and program watched by the user are appropriate. Background technique [0002] With the development and promotion of the digital home, the function of digital TV is more and more powerful, the content of the program is extremely rich, and it occupies an increasingly important position in people's life. Therefore, the damage of digital TV to people's eyes cannot be ignored. Especially for teenagers, many teenagers have vision loss due to not paying attention to viewing distance and time. At the same time, with the enrichment of programs, some adult programs, game shows, horror programs, etc. are not benefic...
