Problems solved by technology

[0003] Because the digital and analog TV compatible all-in-one machine has two sets of digital and analog circuits, which are controlled by their own CPUs and have their own OSDs, when the user operates the TV, he needs to operate the digital and analog forms separately, causing great inconvenience to the user. big inconvenience
Taking OSD as an example, when the user enters "Settings", there will be two OSDs of digital and analog systems appearing at the same time, which will easily cause confusion in the operation
[0004] On the other hand, there are two sets of digital and analog systems in the above-mentioned digital and analog TV compatible all-in-one machine. When the user is watching a program, switching between the digital program and the analog program is quite troublesome, and the user needs to manually switch the working mode of the TV set. cause inconvenience

Embodiment 6

[0052] Fig. 7 is a schematic diagram of the display and operation of the digital-analog television all-in-one machine EPG with machine-card separation in Embodiment 6 of the present invention.

[0053] The figure shows that the EPG (Electronic Program Guide) user interface is also displayed through the menu opening mode of the main control CPU or directly pressing the remote control key. After opening the menu shown by "①" in the figure, the user presses the remote control to select the menu item "Electronic Program Guide" and presses the confirmation key, the master control CPU sends the designated command to the slave control CPU through the three-line bus serial mode, and the slave control CPU After the control CPU receives the command, it opens the display of the electronic program guide shown in "②" in the figure. At this time, the user can use the up, down, left, right and confirmation keys to operate the EPG, and the EPG information of 7 days can be displayed here.

Abstract

Double processor television control method and use thereof, referring to digital-analog integrated television control technology, which contains 1, the first processor the second operation command to second processor, 2, second processor transmitting second operation command to second processor, 3, second processor executing second operation command, all operations are executed in uniform user interface and easy to use like in analog television.

Description

technical field [0001] The invention relates to electronic technology, in particular to the control technology of digital-analog integrated television. Background technique [0002] With the rapid development of digital broadcasting and TV technology, my country plans to close all analog TV signals before 2015. During the transition period of nearly ten years, digital and analog compatible digital TV all-in-one machines and set-top boxes plus analog TV opportunities will be available in the Chinese market. occupy a dominant position. However, the user interface is complex and inconsistent when receiving digital TV signals with a set-top box plus analog TV, which makes user operations extremely inconvenient and also very difficult in commercial operations. According to the opinions of the Ministry of Information Industry and the National Standards Development Committee, it is recommended to develop and use the machine card (PCMCIA card + SMART card) to separate the digital an...
