Embodiment 1

[0022] figure 2 It is a schematic flowchart of an embodiment of the DP-based wireless video output adaptation method of the present invention. Such as figure 2 Shown, method of the present invention comprises:

[0023] Step 21, configuring a DP interface adapter for the large-screen display device in advance, and the DP interface adapter and the large-screen display device are connected through a DP interface.

[0024] In the embodiment of the present invention, small-screen display devices (such as mobile phones, tablet computers, and notebook computers, etc.) support IEEE 802.11ad wireless transmission, and large-screen display devices (such as televisions) do not support IEEE 802.11ad wireless transmission, so the small-screen display The device cannot transmit the video to the large-screen display device through IEEE802.11ad wireless transmission.

[0025] In order to realize wireless transmission of small-screen display devices to large-screen display devices, such a...

Embodiment 2

[0035] Embodiments of the present invention also provide a DP-based video output wireless adaptation system, such as image 3 As shown, including: small-screen display devices, DP interface adapters and large-screen display devices, wherein,

[0036] A small screen display device is used to compress the video data and send the compressed video data to the DP interface adapter;

[0037] In a specific embodiment of the present invention, the small screen display device and the DP interface adapter support IEEE802.11ad wireless communication. Using H264, MPEG, MJPEG and other algorithms, the DP interface adapter compresses 4K video data to meet IEEE802.11ad wireless transmission video data, and based on IEEE 802.11ad wireless communication, sends the compressed video data to the DP interface adapter.

[0038] The DP interface adapter is connected to the large-screen display device through the DP interface, and is used to receive the compressed video data transmitted wirelessly b...

Embodiment 3

[0044] Embodiments of the present invention also provide a DP-based video output wireless adapter device. In a specific embodiment, the device is a DP interface adapter, such as Figure 4 As shown, including: wireless module, video processor and DP interface, wherein,

[0045] The wireless module communicates wirelessly with the small-screen display device, and is used for receiving compressed video data wirelessly transmitted by the small-screen display device.

[0046] In a specific embodiment of the present invention, the small-screen display device and the DP interface adapter support IEEE802.11ad wireless transmission, while the large-screen display device does not support IEEE 802.11ad wireless transmission, in order to realize the wireless transmission of the small-screen display device to the large-screen display Device, configure the DP interface adapter for the large-screen display device.

[0047] The wireless module of the DP interface adapter supports IEEE802.11a...

Abstract

The invention provides a DP based video output wireless adaption method, device and system. The method comprises that a DP interface adapter is configured for a large-screen display device in advance, and connected with the large-screen display device via a DP interface; the DP interface adapter receives video data which is transmitted wirelessly by a small-screen display device, and the video data is compressed video data; and the DP interface adapter decompresses the compressed video data, and sends the decompressed video data to the large-screen display device via the DP interface. The method, device and system can be uses to overcome defects in wired video transmission from the small-screen display device to the large-screen display device, and wireless adaption of video output from the small-screen display device to the large-screen display device is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular to a display interface (DP, Display Port)-based wireless video output adaptation method, device and system. Background technique [0002] With the rapid development of media playback technology in mobile phones and other ultra-portable devices, the application of video in ultra-small size and low power consumption devices is becoming more and more widespread. An emerging feature is the ability to drive the video signal output from a mobile phone to a traditional TV for viewing. Sending video signals to different applications is useful in many ways, such as video conferencing, photo browsing, movie streaming, video telephony, networked games, etc. Therefore, small screen display devices such as mobile phones, tablets, and notebooks use video Applications transmitted to large-screen display devices such as TVs and monitors are already in widespread use.
