Referring to fig. 3, fig. 3 is a schematic flowchart of a video frame playing method according to a first embodiment of the present invention, and based on the above-mentioned embodiments, the video frame playing method further includes:
step S10, when confirming that the playing channel of the current television has the video frame playing requirement, acquiring the video frame information corresponding to the video frame playing requirement;
after the television is started, the access network realizes internet network connection, whether a video EPG electronic program list can be played or not is detected in a current television playing channel, whether the mode of detecting whether the video EPG can be played or not can be a mode of confirming whether the current television is provided with a plurality of decoders for playing the television programs and simultaneously playing the video EPG or can be confirmed through related function setting of the television, and when the current television is confirmed not to be capable of playing the video EPG, the electronic EPG of the television is played in a mode of displaying video frames. Therefore, based on this situation, a video frame acquisition request is sent to the cloud platform that has provided the cloud service interface, so as to acquire the corresponding video frame. Due to the nature of the video frame, when the video frame acquisition request is sent to the cloud platform, the video frame acquisition request is actually an I-frame video frame in a video EPG of a current playing channel, the video EPG is defined as a video file, the video file comprises three video frame formats, and the I-frame video is a video frame of a complete picture. Therefore, the video EPG needs to be replaced by playing the extracted I-frame video frame in a manner of acquiring the video EPG and extracting the I-frame video frame in the video EPG. Therefore, when a video EPG of a next broadcast program of a currently broadcast channel is acquired when a video frame is broadcast, and the video EPG is used as event information acquired by the video frame, a preset video frame acquisition request is generated based on the acquired event information of the video EPG, where the event information of the video frame acquisition request includes a video EPG event identifier and a video EPG event name corresponding to the video EPG, that is, a video frame, and when a video frame acquisition request is generated based on the acquired video frame information, an apparatus parameter of the television is also required to be added, that is, the video frame acquisition request is defined as request _ info, and parameter information included in the request _ info is as follows:
as described above, the video frame acquisition request includes video frame information, and the specific parameter contents are as follows: assigned char [128] event _ name (video EPG event name), assigned int req _ id (video EPG event identification); the television also comprises the terminal parameters of the television, and the specific parameter contents are as follows: signaled int network _ id (wired network identification); signaled int ts _ id (transmission frequency point identification); signaled int service _ id (program identification); signaled int event _ id (EPG event identification).
Step S20, generating a video frame acquisition request by the acquired video frame information, and sending the video frame acquisition request to a cloud platform;
and sending the generated video frame acquisition request to a cloud platform through a cloud platform service interface. When the video frame acquisition request is sent, reading a cloud platform service interface opened by the cloud platform, and transmitting the video frame acquisition request to the cloud platform through the service interface. The request transmission mode is an information transmission mode in the prior art, and is not described herein in detail.
Step S30, when an I frame video frame corresponding to the video frame information acquisition request returned by the cloud platform is received, the I frame video frame is played.
Receiving a video frame storage address returned by a cloud platform, wherein the information of the video frame storage address is used as return information of a sent video frame acquisition request, the return information comprises the video frame storage address, the specific return information is defined as response _ info, and the specific definition content is as follows:
after the video frame storage address is received, reading the content of the video frame storage address, and sending a protocol request to a cloud platform to establish a connection relation of data transmission with the cloud platform, so that the cloud platform transmits a video frame corresponding to the video frame storage address according to the established connection relation after receiving the protocol request. The video frames sent by the cloud platform mainly refer to I-frame video frames in the video EPG, so that the I-frame video frames in the storage address are downloaded for playing after a connection relation with data transmission of the cloud platform is established. The operation of establishing the data transmission connection relationship between the cloud platform and the television is a data transmission mode of the cloud platform in the prior art, and is not repeated herein. The step of playing the I-frame video frame when receiving the I-frame video frame corresponding to the video frame information acquisition request returned by the cloud platform includes:
reading an I frame video frame storage address returned by the cloud platform, and downloading the I frame video frame;
and playing the downloaded I frame video frame.
And downloading the corresponding I frame video frame according to the storage address of the received video frame, wherein the downloading process and the downloading mode are related to a common communication protocol of the television and the cloud platform server. Further, the step of playing the downloaded I-frame video frame includes:
when the I frame video frame is confirmed to be a compressed file, decompressing the I frame video frame;
and playing the decompressed I frame video frame.
Based on the downloaded I frame video frame, when the I frame video frame is played, if the downloaded I frame video frame is confirmed to be a compressed file, the compressed I frame video frame is decompressed to obtain the currently played I frame video frame.
And based on the received I frame video frame, playing the received I frame video frame in a preset video frame playing area of the current television playing page. The preset video frame playing area is a video frame playing area already set in a current television page, and the video frame playing areas set on the pages of different channels may be different, the playing form of the I frame video frame can refer to fig. 5, and in fig. 5, what is displayed in the lower right corner display frame is the video frame playing.
Further, the video frame acquisition request is triggered by replacing the video EPG with a playing video frame when the playing channel is switched based on the television and the currently playing channel is detected to be unable to play the video EPG, that is, each video frame acquisition request is related to the currently playing channel, and the acquired video frame is a video frame of a program played next to the currently playing channel. Therefore, when the channel of the television is switched, the video frame of the previous channel does not have any relation with the switched channel, namely after the channel is switched to another channel, the video information of the next playing program of the current playing channel is detected again, the video frame information of the next playing program is obtained again based on the detected video information of the next playing program, and a video frame obtaining request is sent to the cloud platform.
