Embodiment 1

[0031] According to an embodiment of the present invention, an embodiment of a data transmission method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0032] figure 1 is a flowchart of a data transmission method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0033] In step S102, the transceiver detects whether the received first attribute information is updated, where the first attribute information is attribute information of the playback device.

[0034] Specifically, the above-mentioned transceiver may be a video transmitter in a video transmission system, the above-mentioned attribu...

Embodiment 2

[0074] According to an embodiment of the present invention, an embodiment of a data transmission system is provided, Figure 5 is a schematic diagram of a data transmission system according to an embodiment of the present invention, combined with Figure 5 As shown, the system includes:

[0075] The first transceiver 50 is connected to the first adapter, and is used to detect whether the received first attribute information is updated, and in the case of detecting that the first attribute information is updated, control the first adapter to generate a closing signal, wherein the first The attribute information is the attribute information of the playback device.

[0076] Specifically, combine figure 2 As shown, the first transceiver can be a video transmitter, the first adapter can be a VGA-to-HDMI adapter, the first attribute information can be transmitted to the video receiver by the video playback device through the HDMI-to-VGA adapter, and the video receiver Attribute ...

Embodiment 3

[0100] According to an embodiment of the present invention, an embodiment of a data transmission device is provided, Figure 6 is a schematic diagram of a data transmission device according to an embodiment of the present invention, combined with Figure 6 As shown, the system includes:

[0101] The detection module 60, the transceiver detects whether the received first attribute information is updated, wherein the first attribute information is the attribute information of the playback device.

[0102] The control module 62 is configured to control the adapter to generate a closing signal when an update of the first attribute information is detected.

[0103] The reading module 64 is configured to read the first attribute information stored in the transceiver when the output device detects the closing signal.

[0104] It can be seen from the above that, in the above-mentioned embodiments of the present application, the transceiver detects whether the received first attribut...

Abstract

The invention discloses a data transmission method, device and system. The method comprises the steps that a transceiver detects whether received first attribute information is updated or not, wherein the first attribute information is the attribute information of a playing device; transmitting the first attribute information to an adapter when it is detected that the first attribute information is updated, and controlling the adapter to generate a closed signal; and reading the first attribute information stored in the adapter when an output device detects the closed signal. According to the method, the device and the system, the technical problem in the prior art the output information of the output device mismatches the playing device due to the fact that EDID (Extended Display Identification Data) information is solidified in the VGA-to-HDMI adapter is solved.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a data transmission method, device and system. Background technique [0002] In the wireless video transmission system, the wireless video transmission equipment includes a video transmitter (hereinafter referred to as the S terminal) and a video receiver (hereinafter referred to as the R terminal). The S terminal sends the video signal output by the video output device to the R terminal through a wireless transmission protocol, and the R terminal plays the video signal on the video playback device. In order to ensure that the video playback device and the video output device can achieve the best output effect, it is necessary to transmit the EDID (Extended Display Identification Data) information of the video playback device to the video output device, so as to ensure a good relationship between the two. Negotiate the video resolution to achieve the best output effect. ...
