Embodiment
Below in conjunction with attached drawing, the embodiment of the present invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
As shown in Figures 1 and 3, high-resolution of the present invention obtains the method for picture of televising in real time, including server is built
The vertical communication between client and server, the foundation of server comprise the following steps：（1）Server is gathered and preserved in real time
Multichannel videoblankingsync；（2）Server in real time separates multichannel television signal, gathers each single channel electricity in real time
Depending on voice data in signal, voice data is stored with the form of lossless compression, and extract the vocal print feature code of voice data；Together
When, server gathers the television image of each single channel TV signal in real time, and one, and the figure that will be gathered were gathered every one second
As being stored with picture format；（3）Server repeated the above steps every 60 seconds, refreshed interior data.It follows that at 60 seconds
Time interval server can preserve the images of 60 TV signals.
As shown in Figures 2 and 3, the communication between client and server comprises the following steps：（1）Pass through answering for client
The recording that the TV programme watched with program user carry out；The client is to have setting for sound-recording function and network function concurrently
It is standby, such as mobile phone or tablet computer；（2）Client in a manner of network push, recording file is uploaded and is taken embedded software
Business device；（3）Server receives the recording file that client uploads, and extracts the vocal print feature code of the recording file；（4）Server
The vocal print feature code for the recording file that client is uploaded one by one with TV signal sound number in each single channel for gathering in real time
According to vocal print feature code match, if matching degree is not met, continue to carry out with the voice data of succeeding channel TV signal
Match somebody with somebody, if matching degree meets in a certain range, illustrate that the channel is consistent with the channel that client is recorded；（5）Work as collection of server
Channel it is consistent with the channel that client is recorded when, by the vocal print feature code of TV signal voice data in the channel with record
The vocal print feature code of sound file matches, until finding out and the vocal print feature code of recording file that a part of TV the most matched
The vocal print feature code of signal sound data；（6）The server is according to that a part of TV signal voice data the most matched
Vocal print feature code find with the television image corresponding to the TV signal voice data, server priority by the television image with
Picture format is sent to client, then remaining television image in the channel where the television image is sent to picture format
Client.After client receives the television image of server feedback, user can select needed for oneself according to the actual requirements
Television image, and television image is preserved or processed, meet the needs of itself.
It should be noted that the step of establishing server（3）Mentioned in server be only every 60 seconds refresh datas
Preferred solution, not uniquely, such as can select every data in 30 ~ 120 seconds Refresh Servers, if refresh time is too short, meeting
Cause server operation excessively frequent, be unfavorable for the stability of server, if refresh time is long, to the capacity requirement of server
Also of a relatively high, server is a kind of more preferable scheme every 60 seconds refresh datas.
Communication between above-mentioned client and server can also take in the following manner,（1）Pass through the application journey of client
The recording that the TV programme that ordered pair user is watched carry out；The client is the equipment for having sound-recording function and network function concurrently,
Such as mobile phone or tablet computer；（2）Client first extracts the vocal print feature code of recording file by embedded software, again should afterwards
Vocal print feature code uploads onto the server；Step and above-mentioned steps afterwards（4）To step（6）Identical, which is not described herein again.
In addition, when television image is sent to client by server with picture format, its process can simplify, whole to implement
During, as shown in figure 3, the establishment step of server is identical with the establishment step of above-mentioned server, client and server it
Between communication complete step（1）To step（4）It will directly gather afterwards in the server consistent with client recording channel
Whole television images in channel feed back to client with the form of picture.
By above description as can be seen that the method that the high-resolution that the present invention refers to obtains picture of televising in real time, tool
Have the advantage that：（1）What user was obtained is the image of the pure TV signal of server feedback, and by way of taking pictures
The picture image of televising obtained is compared, and will not include television outer frame or other images unrelated with picture of televising；
（2）User obtains the TV signal image for the high definition for being server feedback, is the most clear image restoring of TV signal, Bu Huiyin
Television set whether high definition and reduce the clarity for picture of televising, image will not be distorted and draw high, not upright enough feelings
Condition；（3）What user was obtained is not merely a pictures, is picture image of continuously televising, and avoids user because TV
The situation that broadcasting pictures are skipped and have little time to preserve information needed occurs；（4）Server mentioned in the present invention gathers in real time
TV signal and timely refresh data, it is relatively low to the capacity requirement of server, even if server capacity is little, it can also meet need
Will, substantially increase operation possibility.
Certainly, the above is the representative instance of the present invention, and in addition, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
