Problems solved by technology

Since the instrument MIK8268 can only store one EDID data, the MIK8268 can only judge two sets of EDID data, so when the test object has at least three HDMI ports, it is necessary to plug and unplug the HDMI cable many times, which affects the production efficiency and wastes meter resources

Embodiment Construction

[0028] The present invention aims to provide a testing method and testing device for multimedia electronic equipment, which are used for detecting EDID data on at least three HDMI ports, so as to avoid multiple plugging and unplugging of HDMI cables.

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] like figure 1 Shown, the testing method of multimedia electronic equipment of the present invention comprises:

[0031] S10. Connect to at least three high-definition multimedia ports of the device under test respectively.

[0032] S20. Read the EDID data corresponding to the high-definition multimedia port and compare it with the corresponding pre-stored EDID data.

[0033] Read the EDID data corresponding to the HDMI port through serial communication, and compare the read EDID data with the corresponding pre-stored EDID data.

[0034] Wherein, the reading the EDID data corresponding to the HDMI port through...

Abstract

The invention discloses a testing method and a testing device for multimedia electronic equipment for carrying out EDID data detection on at least three channels of HDMI interfaces. The testing method for the multimedia electronic equipment comprises the following steps: respectively connecting at least three channels of high definition multimedia interfaces (HDMI) of equipment to be tested; reading extended display identification data (EDID) corresponding to the high definition multimedia interfaces in a serial communication mode and comparing the read extended display identification data with corresponding prestored extended display identification data; and if a comparison result is that the read extended display identification data is different from the corresponding prestored extended display identification data, writing the corresponding prestored extended display identification data into the equipment to be tested by the high definition multimedia interfaces. The testing method and the testing device of the invention can be used for EDID data detection of the at least three channels of HDMI interfaces.

Description

technical field [0001] The present invention relates to a testing method and testing device for multimedia electronic equipment, in particular to a testing method and testing device for testing extended display identification data (Extended Display Identification Data, EDID) of multimedia electronic equipment. Background technique [0002] The purpose of Consumer Electrical Control (CEC) is to connect consumer electronic products such as TV, DVD, set-top boxes, recording equipment, audio systems, etc. Simple. As a display terminal, the TV can directly control other devices on the TV, making the operation of the entire CEC system easier. At the same time, the TV can also receive control from other devices, making the system more intelligent. [0003] The types of CEC command sending are divided into broadcast (Broadcast, BC) sending and direct address (DirectAddress, DA) sending. The target address of BC sending is 0xF, and DA sending needs to be assigned to a logical device...
