While the display unit by the first electronic equipment plays M video frame by the first sequential, the present invention is implemented
The information processing method that example provides enters step S3, i.e.,：At the second time point for being later than first time point, judge that the first electronics is set
Whether the standby transmission rate for receiving video frame is less than a predetermined threshold value.
Specifically, due to during laptop plays M video frame, in order to allow user to watch the M a
There can be smooth feeling when video frame, it usually needs the picture per second for playing 12 frames or more namely frame per second at least need to be more than
It can be by frame of course for making laptop that there is higher fluency when playing M video frame equal to 12 frames/second
Higher, such as 16 frames/second, 30 frames/second are arranged to obtain in rate, therefore, judge that the first electronic equipment receives the transmission rate of video frame
Whether it is less than a predetermined threshold value, can judge that whether the first electronic equipment receives the frame per second of video frame less than 12 frames/second.
If the data transmission channel of laptop is second-rate, such as small in the frame per second of laptop reception video frame
It when 12 frames/second, of courses, it should be noted that 12 frames herein/second is a citing, the skill belonging to this field
Art personnel can be adjusted it according to actual conditions, and to meet the needs of actual conditions, details are not described herein again, because
Video communication is real-time Communication for Power, and the rate that laptop receives video frame is substantially equal to the speed that laptop plays video frame
Rate, it is possible to determine that frame per second when laptop plays video frame can also be less than 12 frames/second, so passing through notebook electricity
When the display screen of brain plays M video frame, it just will appear the situation of " interim card ", when " interim card ", just will appear notes
Shown picture includes the situation of a large amount of ceramic mosaic graphic patterns on the display screen of this computer.
The frame per second of video frame is received except through the first electronic equipment to judge that current data transmission channel is second-rate
Except, message transmission rate when can also receive video frame by first electronic equipment is judged, if for example, the first electricity
When message transmission rate when sub- equipment receives video frame is 5Kbps or is lower, then the first electronic equipment is regarded in broadcasting
It when frequency frame, equally will appear the situation of " interim card ", similarly will appear shown on the display screen of laptop
Picture includes the situation of a large amount of ceramic mosaic graphic patterns.It of courses, it should be noted that 5Kbps is a citing, according to being used
Video communication software, Data Transport Protocol, video compression coding mode etc. difference, technical staff's energy belonging to this field
The size for reaching message transmission rate when adjusting the first electronic equipment reception video frame according to actual conditions, to accurately sentence
The quality of the current data transmission channel of disconnected first electronic equipment, details are not described herein again.
Introduction through this embodiment, the technical staff belonging to this field can select other suitable according to actual conditions
Mode judge the quality of the current data transmission channel of the first electronic equipment, in order to illustrate the succinct of book, herein just no longer
It repeats.
When determining that the first electronic equipment receives the transmission rate of video frame less than predetermined threshold value by step S3, namely really
When the instruction of the fixed current data transmission channel of first electronic equipment is poor, information processing method provided in an embodiment of the present invention into
Enter step S4, i.e.,：A default multimedia file is played by display unit.
Specifically, it on laptop may include a buffer unit, such as can be the memory of laptop
In certain part, N number of video frame in M video frame that laptop receives is buffered in the buffer unit,
Middle N is to be played for the display screen of laptop, according to the big of buffer unit more than or equal to the 1, integer less than or equal to M
It is small, the video frame in certain time length can be cached in the buffer unit, the video frame in the certain time length will include M
Data included by key frame namely the key frame in a video frame are a complete video requency frame data, and do not need to according to
By the data included by other frame.
Therefore, a default multimedia file is played by display unit, can specifically include：Determine waiting for for the second time point
The loss of data region of frame is played, and obtains the previous video frame of the frame to be played, and is determined from the previous video frame
First area corresponding with the loss of data region.And the corresponding video data in the first area is filled into the data
Lost regions obtain the second frame to be played, and substitute the frame to be played with the described second frame to be played and play out.
Specifically, the transmission rate at the second time point be less than predetermined threshold value when, the second time point it is to be played
Frame may be because of data transmission channel degradation, and can not receive corresponding difference data, it is of course possible to be that can not receive
To partial difference data, it is also possible to be that can not receive whole difference datas, in practical applications, unless data transmission channel is complete
It is complete to disconnect, be otherwise not in that therefore, in the present embodiment, introduction can not be received the case where can not receiving whole difference datas
To partial difference data, there is the case where mosaic so as to cause the corresponding region of partial difference data.
In specific implementation process, the frame to be played at the second time point is due to data transmission channel degradation, so can
Energy meeting lost part difference data, then causes frame to be played to will appear mosaic when playing, therefore to solve the problems, such as this, can
First, to determine the loss of data region of frame to be played, such as the data packet of frame to be played can be analyzed, so as to according to number
It determines to show the region of mosaic in packet according to the difference data lost in frame to be played, namely determines the number of frame to be played
According to lost regions.
Then the previous video frame of frame to be played can be obtained from buffer unit, certainly, if the previous video frame is
Key frame need not then be handled it, can be according to the previous video frame pair if the previous video frame is non-key frame
The key frame and difference data answered restore the previous video frame.
Then it from the first area opposite with the loss of data region in frame to be played is determined in previous video frame, waits broadcasting
The loss of data region for putting frame is identical with the position of the first area in previous video frame, so the number in determining frame to be played
It, can be using the coordinate in loss of data region as the coordinate of first area in previous video frame, herein just not after lost regions
It repeats again.
Then, since previous video frame is clearly video frame, so first area is clearly to regard in previous video frame
Frequency evidence, so the corresponding video data in first area in previous video frame is extracted, then as the second time point
Frame to be played loss of data region data, the corresponding video data in first area in previous video frame will also be filled
To the loss of data region of frame to be played, to obtain the second frame to be played.Due to when video communication connects, Yong Huyi
As will not occur big movement namely king-sized variation, and previous video frame and the second time point will not occur for image
Time interval between frame to be played is very short, so can think not deposit on second frame to be played in the first degree
In mosaic area.
Finally, when playing video frame by display unit, frame to be played is substituted with the second frame to be played and is broadcast
It puts, in this way, when playing the second frame to be played, ceramic mosaic graphic pattern would not occur on display unit, so as to avoid existing
There is technical factor second-rate according to transmission channel, leads to the defect for including ceramic mosaic graphic pattern on the image that user seen.
It in practical applications, can be when data transmission channel be second-rate, all the time by aforesaid way to needing
Frame to be played is adjusted so that the video frame played on the display unit of the first electronic equipment does not contain ceramic mosaic graphic pattern.
Certainly, in addition to the scheme of above-mentioned introduction being adjusted to frame to be played, the buffer unit can also directly be played
At least one video frame of middle caching, such as the key frame cached in buffer unit can be played, which will not wrap
Ceramic mosaic graphic pattern is included, or plays multiple video frame in the one section of default physical length cached in buffer unit, such as within 3 seconds
Video frame, video frame in this 3 seconds will not occur including mosaic since key frame is all buffered in buffer unit
The situation of pattern then improves user experience so that user not can be appreciated that the image for including a large amount of ceramic mosaic graphic patterns.
It of courses, in order to which the network quality for accurately prompting the user of laptop current is poor, display can be passed through
Screen plays the nearest video frame of the second time point of distance in buffer unit, if it is aforementioned described key frame, so that it may with
It is directly displayed, if it is non-key frame, a video frame for including complete image is just generated by its corresponding key frame,
And include being enabled a user to according to current fixed aobvious on the display screen of laptop by video frame fixation
The video frame shown knows that the current data transmission channel of laptop is second-rate, while will not lead to because of because of data transmission
Road is second-rate and sees the image with a large amount of ceramic mosaic graphic patterns.
Above by the mode for playing the video frame in buffer unit, provided and the secondary video to the user of laptop
The relevant picture of communication process, solves existing in the prior art because data transmission channel is second-rate, and user is caused to be seen
To image on include ceramic mosaic graphic pattern and fuzzy pattern the technical issues of, in next part, will introduce to notebook
The user of computer provides the picture unrelated with the secondary video communication, existing in the prior art because data transmission is logical to solve
Road is second-rate, leads to the technical issues of including ceramic mosaic graphic pattern and fuzzy pattern on the image that user seen.
Specifically, can be that the default multimedia file being stored in the first electronic equipment is played by display unit；
Or the default multimedia file being stored in third electronic equipment, third electronic equipment and the first electronics are played by display unit
Equipment is connected.
For example, can be played on the display screen of laptop be stored in laptop storage unit it is for example hard
Disk, ROM（Read-Only Memory, read-only memory）In default multimedia file, can also be to play on the display screen
Another electronic equipment being connected with laptop, such as the default multimedia file in USB flash disk or a server, as user is special
Favorite music file, video file etc. multimedia file, these multimedia files are local with laptop due to storing,
On the third electronic equipment being either connected with laptop, so Marseille pattern is not will include on these multimedia files,
The phenomenon that interim card will not occur, so solving existing in the prior art because data transmission channel is second-rate, cause to use
The technical issues of including ceramic mosaic graphic pattern and fuzzy pattern on the image that family is seen, while further solving because of data transmission
Channel quality is poor, leads to the incoherent technical problem of the image seen described in user, to realize provide to the user it is coherent
The technique effect of image, further increases user experience.
Based on same inventive concept, the embodiment of the present invention also provides a kind of electronic equipment, the electronic equipment and the second electronics
Equipment is connected, which for example can be smart mobile phone with the second electronic equipment, tablet computer, laptop, desk-top
