Problems solved by technology

[0002] The existing vehicle-mounted systems are limited by system performance and software architecture, and generally do not support PIP (Picture InPicture, Picture-in-Picture) function
Individual vehicle systems that support the PIP function also use an external dedicated IC (Integrated Circuit, integrated circuit), which is realized by operating the OSD (On Screen Display) layer of the display. The hardware cost is high and the integration is difficult.

Abstract

The invention relates to the technical field of vehicle-mounted multimedia display, in particular to a method and device for achieving picture in picture based on a QNX vehicle-mounted system. The device comprises a main window establishing module, a starting adding module, a child window establishing module and a child window display determining module. The main window establishing module is used for starting a picture in picture program and establishing a main window and a window set. The starting adding module is used for enabling other programs to send messages of adding requests to the window set when the other programs are started. The child window establishing module is used for the main window for establishing child windows corresponding to the other programs according to message notifications and then adding the child windows to the window set. The child window display determining module is used for determining display states of the established child windows. The child windows correspond to the other programs one to one, the display states of the other programs corresponding to the child windows one to one are determined by determining the display states of the child windows, the main window determines the display states of the child windows according to preset child window name information, that is, a user can simultaneously display the child windows on a screen through presetting, and the picture in picture function of the QNX vehicle-mounted system is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted multimedia display, in particular to a method and device for realizing picture-in-picture based on a QNX vehicle-mounted system. Background technique [0002] The existing vehicle-mounted systems are limited by system performance and software architecture, and generally do not support the PIP (Picture In Picture, Picture-in-Picture) function. Individual vehicle-mounted systems that support the PIP function also use an external dedicated IC (Integrated Circuit, integrated circuit), which is realized by operating the OSD (On Screen Display) layer of the display. The hardware cost is high and the integration is difficult. Contents of the invention [0003] The purpose of the present invention is to propose a method and device for realizing picture-in-picture based on the QNX vehicle-mounted system, which can simultaneously display multiple application program interfaces in the QNX vehicle-m...
