Highly efficient intelligent television channel switching method

Abstract

The invention relates to an intelligent television channel switching method with high efficiency. A television signal reception system comprises an antenna, a tuner, a saw filter, a medium frequency processing chip, a base band video processing chip, a display control chip, a microprocessor, a memory, an OSD generator, a display screen, an ADC converter and a power supply processing module which are connected together. The implementation step is as follows: when the system is started for the first time, the space of a nonvolatile store is allocated so as to deposit a common watched channel list and is divided into two channels: one channel counts the time of switching channels of the user and the watching time of every channel when one channel meets a common switching operation of the user, ranks the common watched channel list; whether the list is updated or not is decided; if yes, the list is updated, and a station caption sectional drawing is established; if not, an appointed channel is switched to; the other channel displays the common watched channel list when the other channel meets a common watched channel key of the user; the user selects by top and bottom, right and left, and then updates the list and establishes a station caption sectional drawing. The step of the method is easy, thus effectively solving the difficult problem of switching television programs frequently.

Description

technical field [0001] The invention relates to a television channel switching method, in particular to an efficient and intelligent television channel switching method for the television. Background technique [0002] At present, along with the continuous improvement of the development of society and people's living standard, the application of television is more and more extensive. [0003] There are more and more TV programs now, generally there are more than 50 analog channels, and if digital channels are added, the number of programs has reached more than one hundred. However, the number of programs that are frequently watched usually does not exceed ten. Because the channel numbers of these frequently watched channels are generally not continuous, the user must remember the corresponding channel numbers of the frequently watched channels, or continuously press the channel plus and minus keys to inquire when in use. This brings up the following questions: [0004] (1...
