Description
Technical Field
The embodiment of the invention relates to the technical field of videos, in particular to a Display interface (DP) based video output wireless adaptation method, device and system.
Background
With the rapid development of media playing technologies in mobile phones and other ultra-portable devices, video applications in ultra-small size and low power consumption devices are becoming more and more widespread. One emerging function is to be able to drive the video signal output by the handset to a conventional television set for viewing. It is useful to transmit video signals to various applications, such as video conferencing, photo browsing, streaming, video telephony, networking games, etc., and therefore, small-screen display devices such as mobile phones, tablet computers, and notebooks have been widely used to transmit video to large-screen display devices such as televisions and displays.
Conventionally, as long as a television supports a Universal Serial Bus (USB) playing function, a small-screen display device such as a mobile phone, a tablet computer, and a notebook computer may be connected to a large-screen display device such as a television and a display through a USB interface, so that the small-screen display device is regarded as a mobile hard disk externally connected to the large-screen display device, and video playing is realized through a local playing function of the large-screen display device. However, this approach has the disadvantages that: the small-screen display device is used as a storage space, and all operations can be performed only on the large-screen display device. And if the user does not have a USB connecting line with the small-screen display equipment, the method cannot be realized. In addition, although the USB playing function of the large-screen display device has been available for a long time, the decoding capability of each brand and even each model of tv is different, and a considerable number of large-screen display devices cannot support all streaming Media video formats, for example, the japanese tv still has a common format that many models cannot support RM (RMVB) with a dynamic Variable sampling rate.
Improved prior art may use Digital Living Network Alliance (DLNA) to transfer video from a small screen display device to a large screen display device. Taking a mobile phone and a television as an example, when the mobile phone and the television are accessed to the same network, the DLNA option is opened, and the mobile phone and the television can browse files such as videos, audios, pictures and the like in the storage space mutually. In short, the on-network neighbors play similar to local area network sharing. However, this method is premised on that both the mobile phone and the television support the DLNA function, otherwise, the DLNA function cannot be realized. In addition, the video formats supported by the current DLNA multimedia transmission are still few, and video files coded by H.264 and VC-1 cannot be identified, which are the coding formats of most high-definition files at present.
In addition, there is an improved prior art in which a Video of a small-screen display device is transmitted to a large-screen display device using a Video Graphics Array (VGA) cable, a High Definition Multimedia Interface (HDMI) cable, a DP cable, or the like as shown in fig. 1. The VGA cable has the advantages of high resolution, high display speed, rich colors and the like, is widely applied to the field of color displays, but does not support hot plug and audio transmission; the DP cable is a digital video/audio interface technology, and is a special digital interface suitable for image transmission, which can transmit audio and video signals simultaneously; the DP cable allows audio and video signals to share one cable for transmission, supports various high-quality digital audios, and can be directly used as a transmission channel of low-bandwidth data such as voice, video and the like. However, the experience is not perfect because all cables are based on wired transmission through the VGA cable, the DP cable or the DP cable.

Therefore, DP is very suitable for set-top boxes, personal computers, video games, digital audio and television sets, and the like.

In order to realize the wireless transmission of the small-screen display device to the large-screen display device, as shown in the schematic diagram of the architecture of the video output wireless adaptation system of the present invention shown in fig. 3, both the DP interface adapter and the small-screen display device support IEEE802.11ad wireless transmission, so that the DP interface adapter and the small-screen display device can perform wireless communication based on IEEE802.11 ad.
