Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In order to support wireless screen projection, the current source devices such as smart phones and PCs, relay devices such as routers, and display devices such as displays, televisions, projectors, and small-pitch LED screens are mostly used: DLNA, miracast, airplay and other manufacturers' similar wireless screen projection protocols, the protocol profiles are shown in the following table.
Currently, there is no known technology for supporting a "screen-casting fast-start" display device, and generally, the display device is turned on first through an intermediate operation (physical or touch key operation, remote control operation, mobile phone APP remote control operation, etc.), and then a source end (such as a smart phone, a PC, a tablet) is used to initiate a wireless screen-casting display.
Several prior art application scenarios are briefly described below.
Scene one: when a smart television user wants to screen a mobile phone Youkou client movie, the user needs to find a remote controller or use a mobile phone screen control APP, remotely control to start a television, play television advertisements (about 20-30 seconds are different at present), start screen projection operation, select a WIFI node screen projection target, and display pictures.
Scene two: when a meeting is about to be opened in a conference room, a host needs to find a remote controller to start a projector or a television (sometimes the physical starting button of projection equipment installed at the top needs to be directly operated), waits for starting, starts screen projection operation, selects a WIFI node to project a screen target, and displays a picture.
Summarizing the above two application scenarios, the conventional screen projection operation flow is shown in fig. 1. Fig. 1 is a schematic diagram illustrating a process of starting up and projecting a screen of a display device in the prior art, and the above fig. 1 and the prior screen projection experience can be used to summarize the following disadvantages of the prior art:
1. the operation process is complicated (for example, sometimes a remote controller needs to be found everywhere, or a television and a set-top box need to be operated to start the device, sometimes a user needs to ascend to start the intelligent projection device on the top of the conference room, and the user needs to have the step of starting the device and wait for the display device to be started and the advertisement to be played).
2. The universality and the convenience are poor (for example, the current popular mobile phone needs to be provided with the screen control APP to control the display device, the mobile phone is generally suitable for being used in families and is not suitable for public occasions such as business occasions, for example, a large public meeting room of a certain company, and speakers different in different meetings need to be provided with the screen control APP to operate the display device by using a smart phone or a PC notebook computer, which is unrealistic).
3. When the display device is in a shutdown state or a standby state, a WIFI module of the display device is in a power-off state daily, so that a WIFI node cannot be found and timely connected by a route and a source end.
4. The power-on process of the display device is slow (for example, logo display, more boot applications of the smart television are loaded, and long-time advertisement insertion exists).
However, in the current society, people are already in smart application environments such as smart homes, internet of things devices, and the like, user experience is an important index, and some steps in the current traditional operation modes can be omitted or further optimized: for example, "the display device is started by physical operation" and "the display device is waited for normal operation" in the screen projection operation process. The problem to be solved by the embodiment of the present invention is: the traditional screen projection operation link is reduced, and the screen projection and starting processes are optimized.
A solution of screen-casting quick start is provided, an operation concept of 'casting immediately and opening immediately' is provided, and the scheme can better improve the operation experience of users such as family screen casting, business meeting screen casting and the like.

S503, because the whole equipment is powered on, all tasks are undertaken by the image main processing chip at this time, and the process is ended after the processing is finished.
S504, whether the data packet is a screen-casting initiation protocol is analyzed, if yes, step S505 is executed, and if not, the step S501 is returned.
And S505, powering on the whole machine through power supply operation, and transferring screen projection information to the image processing main chip.
S506, the image processing main chip receives the screen projection command and bypasses the LOGO display lamp to start up quickly.
And S507, starting screen projection display.
And S508, enabling the screen projection protocol pre-analysis module to enter a dormant state, and ending the process.

s601, the image main processing chip receives a data packet sent by WIFI.
S602, judging whether the current data packet is a screen-on shutdown protocol, if not, executing the step S605 and then returning to the step S601, and if so, executing the step S603.
S603, the image main processing chip wakes up the screen projection protocol pre-analysis module in the dormant state.
And S604, powering off the display equipment by the image main processing chip. After the power is off, the WIFI module, the screen projection protocol pre-analysis module and the traditional remote control infrared/Bluetooth receiving module all work normally.
And S605, executing conventional WIFI data processing.
It should be noted that the screen projection protocol pre-analysis module and the image main processing chip respectively perform their functions: the former is used for starting the device, and the latter is used for waking up the screen projection protocol preresolution module and shutting down and other conventional processing. Of course, the interactive logics can be modified and optimized according to actual conditions. For example, case 1: in the shutdown process, the whole equipment can be powered off by the image main processing chip, and the power can also be powered off by the screen projection protocol pre-analysis module after the screen projection protocol pre-analysis module is awakened. Case 2: the screen projection protocol pre-analysis module can also be operated in a low-power consumption working state (no matter whether the display equipment is operated or in a power-off state), at the moment, the screen projection protocol pre-analysis module can be used for transferring WIFI data, and the screen projection protocol pre-analysis module can analyze protocol contents to control power on and power off.
