Abstract

Aiming to the defect of unreasonable use of push-button control function in current dual system electronic device, this invention discloses a control device of whole push-buttons of dual system dual system electronic device, including A electronic device system, B electronic device system, further including a push-button unit, a system identifying unit, a system push-button converting circuit, dual push-button executing circuit; the output of the push-button unit is respectively connected with control input ends of the system identifying circuit and the dual push-button executing circuit; theoutput of the system identifying circuit is connected with the input of the system push-button converting circuit; the output of the system push-button converting circuit is connected with the signalinput end of the dual push-button executing circuit; the input of the dual push-button executing circuit is connected with control signal input ends of A electronic device system and B electronic device system; the output signal of working state of A system is connected with the signal input end of the system identifying circuit. This invention is conveniently operated and is suitable for the dualsystem electronic device.

Description

technical field [0001] The invention relates to a key control device in dual systems, in particular to a key control device for dual system electronic equipment. Background technique [0002] At present, more and more electronic equipment adopts the integrated method of dual control system or multi-control system to realize the multifunctionality of products, such as TV sets with dual systems of TV and DVD; with digital TV (DVB-C) and Digital and touch integrated TV with analog TV dual system; digital and touch integrated TV with European digital TV (DVB-T) and analog TV dual system. How to reasonably use the button control function of the dual systems in these dual-system electronic devices has various methods, each of which has its own characteristics. Common ways are as follows: [0003] 1. Master-slave control system: [0004] This method is to use an important control system in the dual system as the main control system, operate the keys on the system, and the main s...
