Embodiment Construction
[0015] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0016] figure 1 It is a schematic flow chart of an embodiment of the present invention based on a mobile phone for transmitting infrared remote control signals.
[0017] The process begins at step 101 by pulsing the remote control code on an output pin of the mobile phone's processor chip. The remote control coding pulse includes a pilot pulse and a continuous 32-bit binary code group, in which the first 16 bits are user identification codes to distinguish different TV receivers, and the last 16 bits are 8-bit operation codes and their 8-bit inverse codes.
[0018] In step 102, pulse amplitude modulation is performed by a 38 KHz carrier.
[0019] In step 103, a drive circuit amplifies the modulated signal.
[0020] In step 104, the amplified pulse amplitude modulation signal drives an infrared diode to send an infrared remote control signal.

The invention provides an infrared remote control device of a television capable of downloading a television station directory and displaying a television station name based on a mobile telephone. The device can download the television station directory through the mobile telephone connected to internet. The user can select the nearest position, a television program source and a television signal receiving device to download the television station directory through a user interface provided by the mobile telephone. The downloaded television station directory comprises the television station name and a remote control code of a remote controller of the television signal receiving device. The user can display the television station name through the user interface provided by the mobile telephone, can directly select the television program according to the television station name, and then convert the television station name into a remote control code pulse and finally emit an infrared remote control signal to remotely control the television signal receiving device through an infrared signal generator.
Description
technical field [0001] The present invention relates to mobile phone applications. Background technique [0002] At present, most families have television sets, and watching TV programs through cable TV, digital TV and satellite TV is also the first choice for many people's home entertainment. With the popularization of mobile phones, the proportion of people with mobile phones is increasing year by year. And mobile phones all have chip processing capability and good user interface which are incomparable with ordinary remote controllers. Ordinary remote controls can only provide some button functions, and the functions of human-computer interaction are relatively weak. Some users only use a limited number of two or three keys to select hundreds of TV programs. [0003] In order to provide a good user interface for watching TV users with extremely low extra cost, the present invention uses mobile phones to connect to the Internet to download TV station catalogs, uses mobil...
