Embodiment 1

[0018] Such as figure 2 shown. When the system completes the automatic search of digital or analog broadcast TV programs or searches in other ways, the main controller will store the relevant information of analog broadcast TV programs according to the total number of analog broadcast TV programs (APN) found at last, and The sum of the number and the number of digital broadcast TV programs is used to store the relevant information of digital broadcast TV programs.

[0019] If the total number of analog broadcast TV programs is less than or equal to 200, the main controller will store the relevant information of these analog broadcast TV programs, including program number (1-APN), frequency (49.75~863.25MHZ), color system (automatic, PAL , NTSC3.58, NTSC4.43, SECAM), sound system (D / K, B / G, I, M), program skip information (SKIP ON / OFF), program status: analog.

[0020] If the total number of analog radio and television programs is greater than 200, the main controller will g...

Embodiment 2

[0025] see image 3 , this example is the process of program switching. The system first detects whether the broadcast TV program before the channel change is in a digital state? If the radio and TV program before the system changes channels is in digital state, then detect whether the state of the radio and TV program input by the user with the number keys is in digital state; The two-way communication method sends it to the slave controller. After receiving the program number, the slave controller directly switches the digital broadcast TV program to the digital broadcast TV program corresponding to the program number; if the state of the input broadcast TV program is analog, the master The controller first controls the switching organization of the video channel, automatically switches to the analog video channel, and then switches the analog broadcast TV program to the analog broadcast TV program corresponding to the program number. If the broadcast TV program before the s...

Embodiment 4

[0027] Figure 4 It is another program switching process. The system first detects whether the digital / analog state of the broadcast TV program before the channel change is consistent with the digital / analog state of the TV program to be switched to? If the digital / analog status of the latter is consistent with that of the former, the main controller does not need to switch the video channel, and directly switches the analog or digital broadcast TV program to the analog or digital broadcast TV program corresponding to the program number; if the latter is consistent with the former If the digital and analog states of the digital and analog channels are inconsistent, the master controller first switches the video channel to an analog or digital video channel according to the former digital or analog state, and if the latter is in a digital state, then transmits the program number to the slave controller through two-way communication. After the controller receives the program nu...

Abstract

The method comprises: using a universal sequence to number all received analog and digital TV program; when saving the serial number of TV program, simultaneously saving the state of TV program; whenswitching the TV program, checking the state of TV program; for the switching between the programs in different states, simultaneously switching the video channel. By the invention, the video channelcan be automatically switched according to the state of either digital TV program or the analog TV program so as to simplify the switch method.

Description

technical field [0001] The invention relates to television technology, in particular to a digital / analog compatible television program management method. Background technique [0002] With the development of digital TV technology, digital TV broadcasting will gradually replace analog TV broadcasting. Due to the extensive social base of analog TV and the imbalance of economic and technological development in various countries and regions, it will be a long process for digital TV to replace analog TV. In this process, there is a transition period in which digital TV and analog TV coexist, which provides an opportunity for the development of digital / analog compatible TV. During this period of transition from analog broadcast TV signals to digital broadcast TV signals, digital / analog compatible TV sets will dominate the market. However, adopting two sets of receiving systems for analog or digital broadcast TV signals, respectively storing and managing the corresponding analog ...
