Abstract

The invention relates to a vehicle-mounted display control system, in particular to a vehicle-mounted multi-screen interaction system which is used for coordinately controlling contents displayed by internal display screens of multiple vehicles and controlling commands. A main display screen is connected with main display processing equipment and is connected with a master controller through the main display processing equipment. Each rear-row display screen is connected with one slave control equipment. The slave control equipment is connected with the master controller through a video switching module. The video switching module is used for switching the rear-row display screen and the main display screen between a synchronous display mode and an independent display mode. The vehicle-mounted multi-screen interaction system uses independent slave control equipment and audio / video switches which are connected with the master controller, and the master controller can realize independent control between the rear-row display screens and the main display screen through the operation of users; the displayed contents and output voices can be different; the display effect is good, high resolution is supported and the anti-interference capacity is strong; and rear-row passengers can have more free video and audio selection and operation experiences.

Description

technical field [0001] The invention relates to a vehicle-mounted display control system, in particular to a vehicle-mounted multi-screen interactive system for coordinating and controlling display contents and control instructions of display screens in multiple vehicles. Background technique [0002] As cars become more and more popular in China, corresponding on-board electronic products are also becoming more and more popular! The entertainment of in-vehicle products is also getting stronger and stronger. Such as figure 1 As shown, at present, the core of most car navigation multimedia entertainment systems is the circuit of the main unit, and the use of the rear pillow screen is mostly to display the video signal output by the main unit, and the picture displayed on the rear pillow screen is consistent with the main unit screen; You can see the same screen as the front host. But the disadvantage is that the rear pillow screen cannot be operated, and it lacks operabili...
