Set top box with universal remote control function

Abstract

The invention discloses a set top box with a universal remote control function, which consists of a set top box terminal and a handheld control terminal. The set top box terminal comprises a controller, an audio and video processing module and an input and output terminal. The handheld control terminal comprises a controller and buttons. The set top box is characterized in that the set top box terminal is provided with an RF (radio frequency) wireless transceiving module and an infrared code system database. The handheld control terminal is provided with an infrared emitting module, an RF wireless transceiving module and a storage. The RF wireless transceiving module of the handheld control terminal is matched with the RF wireless transceiving module of the set top box terminal, the set top box selects infrared control codes of a device to be controlled from the infrared code system database to transmit to the handheld control terminal through the RF wireless transceiving module and store in the storage, so that infrared signals emitted by the infrared emitting module of the handheld control terminal are matched with an infrared receiving module of the device to be controlled. A user can visually select brands and specifications of devices to be controlled through the set top box with the universal remote control function and can use the set top box conveniently.

Description

technical field [0001] The invention relates to a device for controlling video or audio, in particular to a control set-top box and a remote control device matched with the set-top box. Background technique [0002] In today's technology, all kinds of TVs are generally controlled by infrared rays. With the development of technology, set-top boxes have become a common configuration in conjunction with TVs, used to input digital TV signals, network signals, etc., and as other audio and video Signal access control device. [0003] The set-top box and TV need to be controlled separately. For the convenience of users, there are two existing solutions. One is to use a learning-type infrared set-top box remote control, and use infrared sensors to control some buttons on the TV remote control (usually including power switch, volume control, and input switching). The remote control of the set-top box can be learned from the remote control of the set-top box, so that the remote cont...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above two solutions are: (1) It is inconvenient to learn or set. Among them, the learning operation of the learning remote control is complicated, and the situation of learning failure often occurs. Inconvenient; the remote control with a code system database needs to query the corresponding codes of TVs of different brands and models and set them up. When the TV brand and model used are not in the database, it cannot be used, and the code system database occupies the remote control The storage space is inconvenient for the design of the remote control that strives for miniaturization

(2) The remote control of the set-top box is an infrared remote control. In the current situation that the set-top box is more and more installed in a hanging and hidden way, this type of remote control can no longer meet the needs of use.
