Abstract

The invention discloses a format conversion method, which is used for simplifying the format conversion process and improving conversion efficiency. The method includes: receiving a data packet sent by the first electronic device, the data packet including information to be displayed in a first display format supported by the first interface; obtaining information for judging whether to display the information to be displayed The display format is converted from the first display format to at least one related information of a second display format; based on the related information, it is judged whether the display format of the information to be displayed needs to be converted from the first display format to the The at least one second display format; when the judgment result is yes, converting the display format of the information to be displayed from the first display format to the at least one second display format. The invention also discloses a format conversion circuit for realizing the method.

Description

technical field [0001] The invention relates to the technical field of computers and electronics, in particular to a format conversion method and a format conversion circuit. Background technique [0002] In a Hybrid (hybrid) system, there are two hardware systems: an X86 (an operating system) system and an ARM (an embedded system) system. Since the two systems aim at different directions, there are different mainstream display interfaces in their respective fields. For example, the X86 system has LVDS (Low-Voltage Differential Signaling, low-voltage differential signal) interface, DVI (Digital Video Interface, digital video interface), DP (DisplayPort, display interface), HDMI (High Definition Multimedia Interface, high-definition multimedia interface ) and other types of interfaces, while the ARM system has RGB parallel ports (video interface divided into three primary colors), MIPI DSI (mobile industry processor interface display serial interface) and other types of inte...
