A method and system for switching working states of a modular TV card terminal

Abstract

The invention discloses a method and a system for module television card end work state switching. The method comprises steps that, that a designated button is pressed is detected, whether a work state of a present system is in a normal state is determined; if the present system is in a dormancy state or a shutoff state, the system is controlled to activate to recover to normal work; if the present system is in the normal work state, whether pressing duration of the designated button surpasses a first pre-determined threshold is determined, if yes, a screen end sends a mandatory shutdown command to a card end, the screen end and the card end are controlled for shutdown; if not, the screen end notifies input of the designated button of the card end, the card end is dynamically switched to a corresponding work state, and the screen end is switched to a work state corresponding to the work state of the card end. Through the method, when an intelligent card of the card end of a module TV is replaced, through communication between the screen end and the card end, a work state of the intelligent card is switched correspondingly, when new functions or work states are introduced, the whole module TV can realize corresponding functions, and the module TV is convenient to realize work state switching.

Description

technical field [0001] The invention relates to the technical field of smart TVs, in particular to a method and system for switching working states of a modular TV card end. Background technique [0002] The modular TV is different from the traditional TV. The main board of the traditional all-in-one machine is divided into smart card + screen end board. As a component that is easy to upgrade, smart cards will produce many different product forms. For example, there are basic smart cards that are only used for watching TV, and may only have normal display and shutdown status. Some, such as TV smart cards with monitoring functions, will have normal display and fast wake-up status. For another example, some TV smart cards with router functions will have normal TV display and feature cards will continue to work. For the modular TV with ordinary smart card, if it is replaced with a non-ordinary smart card, such as the smart card with routing function mentioned above, then the ...

Problems solved by technology

[0004] For all-in-one TVs or modular TVs with a single working state, the modular TV here refers to the modular TV that only realizes the TV function. The module replaced by this TV is also a module with only the TV function, and the working status is fixed. During the process, no new elements will be added, but for modular TVs, due to the replaceable modules, new functions or new components will be integrated into the new modules, and thus introduced into TVs. When it is necessary to change the working state, the module TV cannot realize the corresponding function according to the introduction of new functions and states
