Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
At present, the virtual reality technology has been widely applied to wearable devices, but synchronous display devices used in the market are all connected with VR devices in a wired connection manner, so that the images of the VR screens are displayed on the display devices. Because the connection between the VR equipment and the display equipment is limited by the wired connection, the use range of a user is limited, and the wired wires are easy to be wound together in the use process of the user.
In order to solve the problem that communication connection is performed between a VR device and a display device in a wired connection manner in the prior art, an embodiment of the present application provides a video display method, where video format information of a video to be displayed is acquired from the VR device through the display device, when a video format supported by the display device matches a video format of the video to be displayed, a display parameter is sent to the VR device, and the video to be displayed after parameter adaptation is further acquired from the VR device and displayed.
A video display method and apparatus of an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a video display method according to an embodiment of the present disclosure.
The display method in the embodiment of the application is executed by a display device, wherein the display device may be a hardware device having various display systems, touch screens and/or display screens, such as a mobile phone, a tablet computer, a television, a projector, and the like.
As shown in fig. 1, the video display method includes the steps of:
The video format is an identifier given to a video file by video playing software to play the video file. The video formats can be divided into two categories, namely local video suitable for local playing and network streaming media video suitable for playing in a network. Common video formats are: moving Picture Experts Group (MPEG), Audio Video Interleaved (AVI), Advanced Streaming Format (ASF), Streaming media format (FLASH Video, FLV), and the like.
It should be noted that, when the display device plays the video, the client that needs to play the video identifies various video formats, and then the decoding chip performs decoding processing, and then plays the decoded data. The client playing the video can play videos in multiple video formats at the same time, and the video formats played by different client playing the videos are not completely the same. For example, the corelayer player can play various formats such as AVI, WMV, MP4, etc., and the RUN player can play various formats such as RM, RMVB, etc.
In the embodiment of the application, the virtual display technology is a computer simulation system capable of creating and experiencing a virtual world, a simulation environment is generated by a computer, and the system simulation is an interactive three-dimensional dynamic view and entity behavior system simulation with multi-source information fusion, so that a user is immersed in the environment. Virtual reality equipment that uses commonly at present has two kinds of VR all-in-one and VR split machine.
Specifically, the display device can acquire video format information of a video to be displayed in the display device from the VR device through a wireless communication connection established in advance with the VR device.
The supported video format refers to a video format that matches a video format that can be played by the display device, that is, a video format that can be played in the display device.
In the embodiment of the application, after the display device acquires the video format information of the video to be displayed from the VR device, when it is determined that the video format supported by the display device matches the video format of the video to be displayed, the display parameter is sent to the VR device, and then the VR device can adapt to the parameter of the video information to be displayed according to the display parameter received from the display device. The display parameters are video format information supported by the display device and sent to the VR device by the display device, and are used for the VR device to perform parameter adaptation on the video to be displayed. Such as resolution, frame rate, video coding, transmission speed, etc., of the supported video.
For example, if the video formats supported by the display device are AVI, MP4, and AVI, and the video format of the video to be displayed acquired by the display device from the VR device is AVI, the video format supported by the display device is matched with the video format of the video to be displayed, and further, the display device sends the display parameters to the VR device, so that the VR device performs parameter adaptation on the video to be displayed according to the received display parameters.
And 103, acquiring and displaying the video to be displayed after the parameters are adapted from the VR equipment.
In the embodiment of the application, the VR device performs corresponding parameter adaptation on the video to be displayed according to the received display parameters corresponding to the video format supported by the display device, so that the video to be displayed after the parameter adaptation is performed is encoded, and the video to be displayed is sent to the display device through a real-time video transmission protocol, so that the display device can acquire the video to be displayed after the parameter adaptation.
As an example, if the optimal resolution of the video format information supported by the display device is 1280 × 1024, the display device generates the supported display parameters according to the optimal resolution, and then the display device sends the display parameters to the VR device, the VR device performs parameter adaptation on the video to be displayed according to the received display parameters, after adjusting the resolution of the video to be displayed, encodes the adjusted video to be displayed, and sends the video to be displayed to the display device through a real-time video transmission protocol, so that the display device can obtain the video to be displayed after the resolution adjustment from the VR device.
In the embodiment of the application, after the display device acquires the video to be displayed after the parameter adaptation from the VR device, the video to be displayed is decoded, so that the video to be displayed after the parameter adaptation is displayed on a display screen of the display device.
As an example, if the display system of the display device is an Andriod system, when a video to be displayed, which is acquired by the display device from the VR device, is encoded, the display device may decode the video to be displayed according to a self-contained processing mechanism such as MediaCodec, and then the display device displays the processed video to be displayed.
According to the video display method, the video format information of the video to be displayed is obtained from the VR equipment, when the video format supported by the display equipment is matched with the video format of the video to be displayed, the display parameters are sent to the VR equipment, and the video to be displayed after the parameters are adapted is further obtained from the VR equipment and displayed. According to the method, the parameter adaptation is performed on the video to be displayed through the display parameters of the display equipment acquired by the VR equipment, so that the video to be displayed after the parameter adaptation is displayed by the display equipment, the parameter adaptation is performed on the video to be displayed according to the parameter information supported by the display equipment, the display effect of the display equipment is optimal, and the use experience of a user is improved.

As a possible implementation manner, the VR device searches for a display device which can support WI-FI P2P nearby through WI-FI P2P (also called WI-Fi Direct), and when finding the display device A which can support WI-FI P2P, the VR device reminds the user that the display device A has been searched through displaying prompt information, and at the moment, the user can select whether to pair with the display device A or not according to needs. When a user determines that the VR equipment is paired with the display equipment A, the VR equipment sends a pairing request to the display equipment A, and after receiving the pairing request sent by the VR equipment, the display equipment A establishes a wireless communication link with the VR equipment.

As a possible case, the display device determines, according to the supported video formats, a maximum frame rate that matches the supported video formats from among the plurality of frame rates supported by the display device, so that a display screen when the supported video formats are played back is smoother.
And step 205, generating display parameters according to the maximum frame rate, and sending the display parameters to the VR equipment.
Specifically, the display device generates display parameters according to the determined maximum frame rate matched with the supported video format, and sends the generated display parameters to the VR device, so that the VR device performs parameter adjustment on the video to be displayed according to the display parameters.
In step 204 and step 205, the display device determines a maximum frame rate matching the supported video format from the supported video formats according to the supported video formats, and further generates the supported display parameters according to the maximum frame rate. As just one possible case of generating the display parameters, the display parameters may also include resolution, video coding, compression mode, and the like, and the display device may also generate the display parameters including parameter information of resolution, video coding, compression mode, and the like, according to the supported video format. The specific generated display parameters are determined according to actual needs, and are not limited herein.
And step 206, acquiring the video to be displayed after the parameter adaptation from the VR equipment and displaying the video.
In the embodiment of the present application, the implementation process of step 206 refers to the implementation process described in step 103 in the above embodiment, and is not described herein again.
