Embodiment Construction

[0017] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0018] figure 1 It is a block diagram of the application framework of the signal transmission method of the embodiment of the present invention. The signal transmission method is realized by the signal transmission device and the TV set, wherein the signal transmission device mainly completes the reception of the pre-transmission data and judges the type of the pre-transmission data; wherein Receiving the pre-transmission data is specifically receiving TV control data for controlling an external TV; judging the type of the pre-transmission data, that is, judging whether the status of the flag in the data packet of the pre-transmission data is 1 or 0. If the state of the flag bit in the data packet of the pre-transmission data is 1, that is, the pre-transmission data is a large-capacity data packet, then the pre-t...

Abstract

Embodiments of the present invention relate to a signal sending method and device and a remote controller of a television. In the embodiment of the present invention, a signal sending device is used to receive the pre-transmission data, and judge the type of the pre-transmission data; if the pre-transmission data is a large-capacity data packet, the pre-transmission data is converted into a data bus signal for transmission; if the pre-transmission data is For small-capacity data packets, the pre-transmission data is infrared encoded and converted into infrared signals for transmission, and the data is transmitted to the complete TV set. The embodiment of the present invention avoids large-scale modification of the whole program of the TV set, and realizes the compatible use of the infrared remote controller. Therefore, the embodiment of the present invention can save the development time of the TV set and reduce the development burden of the TV set.

Description

technical field [0001] The invention relates to a signal sending method and device and a TV remote controller, in particular to a signal sending method and device which can be used for sending radio frequency signals and infrared signals and a TV remote controller. Background technique [0002] At present, many electrical remote controllers in the family mostly use infrared remote control technology. However, infrared technology has certain defects, and the biggest defect is that it can only be transmitted in a straight line. The first thing the user has to do is to find the infrared receiving window on the controlled device, so as to adjust the angle of the remote controller for control. As interior decoration and furniture are becoming simpler and simpler, electronic devices are often embedded in walls or placed behind closets, where infrared rays cannot reach. [0003] As an alternative to point-to-point transmission of infrared remote controls, the remote control can us...
