Step S50, treats sharing video frequency according to default checking algorithm and carries out verifying to obtain the first check code, and by this
One check code is encapsulated in encapsulation program stream, regards based on waiting to share in default checking algorithm verification encapsulation program stream for server
Frequency obtains the second check code, and comparison the second check code and the first check code, and server is only in the first check code and the second verification
The encapsulation program stream received is preserved as not playing encapsulation program stream during code coupling.
Intelligent television is determining after sharing video frequency, treats sharing video frequency according to default checking algorithm and verifies, and obtains
First identifying code, and the first check code is encapsulated in encapsulation program stream to send in the lump to server；Server is receiving
After the encapsulation program stream that intelligent television sends, parse and treat sharing video frequency and the first identifying code, be then based on presetting checking algorithm
Treating that sharing video frequency verifies to parse, it is thus achieved that the second identifying code, then server compares the first check code and the second school
Test code, when the first check code and the second check code is identical or coupling time, i.e. treat sharing video frequency in upload procedure no data loss,
Server reservation is currently received treats sharing video frequency；When the first check code and the second check code differ or do not mate, show
Treat that sharing video frequency is likely to occur in that data degradation, server to abandon currently in upload procedure and treats sharing video frequency；Thus it is favourable
Treat whether sharing video frequency occurs that data degradation verifies in server to upload, it is to avoid server retains and issues
Show data degradation treats sharing video frequency, improves the effectiveness treating that sharing video frequency is shared.
Further, on the basis of intelligent television video sharing method first embodiment of the present invention, intelligent television is proposed
Video sharing method the 3rd embodiment, with reference to Fig. 4, in the third embodiment, step S20 includes:

Group word number is as the first word number, using the phrase number of the second phrase as the second phrase number；
Step S23, compares word in the first phrase with word in each second phrase one by one, obtains the first phrase
With the same word number that each second phrase has same word；
Step S24, according to the first word number, the second phrase number and the same word number of all correspondences, calculates and compares phase
Like degree.
Present invention can be suitably applied to English filename, Chinese file name and the participle of Chinese and English mixed file name, due at English
In the style of writing of literary composition, using space as natural delimiter between word, so the participle of English filename is relatively simple, do not do
Explain in detail；The most first by Chinese and English differentiation during Chinese and English mixed file name participle, and respectively Chinese and English are entered
Row participle；And Chinese only word, sentence and section simply can be demarcated by obvious delimiter, word neither one is pro forma only
Delimiter, so the participle of Chinese is complex, mainly explains Chinese Word Automatic Segmentation, and Chinese Word Automatic Segmentation is by a Chinese character
Sequence is cut into one by one individually word, namely according to certain specification, continuous print Chinese character sequence is reassembled into word order
The process of row.Certainly, the segmentation methods of the present invention is not limited to Chinese Word Automatic Segmentation.
Chinese Word Automatic Segmentation generally comprises character match method, understanding method etc., and character match method is will according to certain strategy
Chinese character string (being equivalent to treat sharing video frequency filename) to be analyzed (is equivalent to file rank with " the biggest " machine dictionary
Filename in table) in entry join, if finding certain character string in dictionary, then the match is successful；Understanding method is by allowing
The understanding of computer mould personification distich, reach to identify the effect of word, its basic thought carry out while participle exactly syntax,
Semantic analysis, utilizes syntactic information and semantic information to process Ambiguity；Wherein matching method application is relatively broad, the present embodiment
Application matching method, illustrates the embodiment of the present invention with matching method below.
To treat that the filename participle of sharing video frequency, as multiple words, specifically may is that excellent based on the Chinese norm set
First identify in the filename treat sharing video frequency and be syncopated as some with obvious characteristic word (verb such as such as "Yes", " having ",
The word that numeral is had a common boundary with Chinese character, the English word etc. having a common boundary with Chinese character), using these words as breakpoint, old file name can be divided into relatively
Little Chinese character string, splits the Chinese word library that Chinese character string goes coupling to preset, tear identical with Chinese word library in filename the most in order
After point, Chinese character string is as a word.
Such as, treat that the file of sharing video frequency is entitled " the Bird's Nest gymnasium opening ceremony on-the-spot broadcasting of 2008 Beijing Olympic Games year ",
Then passing through segmentation methods can participle be " 2008 ", " year ", " Beijing ", " Olympic Games ", " Bird's Nest ", " gymnasium ", " opening ceremony ",
" on-the-spot ", " live " nine words, these nine words collectively constitute the first phrase, and the i.e. first phrase is the collection of these nine words
Closing, using the word number in the first phrase as the first word number, the i.e. first word number is 9.
List of file names includes the filename of three sharing video frequencies, is filename one, filename two and file respectively
Name three, filename one is " 2008 Beijing Olympic Games ", and the second corresponding phrase A is { " 2008 ", " year ", " Beijing ", " Olympic Games
Meeting " }；Filename two is " Beijing Olympic Games in-situ match ", the second corresponding phrase B be " Beijing ", " Olympic Games ", " match ",
" on-the-spot " }；Filename three is " 2008 Opening Ceremony of the Games ", and the second corresponding phrase C is { " 2008 ", " Olympic Games ", " opening
Formula " }, and then show that the number (the i.e. second phrase number) of the second phrase is 3.
Then being compared with the word in the second phrase A one by one by the word in the first phrase, identical word has
" 2008 ", " year ", four the identical words in " Beijing " and " Olympic Games ", so being 4 with word number A；In like manner the first phrase and
Same word number B of two phrase B is 3, and the same word number of the first phrase and the second phrase C is 3.Then according to the first word number (value
It is 9) and with word number A (value is 4), obtain the first phrase and primary similarity A of the second phrase A, according to the first word number (value
It is 9) and with word number B (value is 3), obtain the first phrase and primary similarity B of the second phrase B, according to the first word number (value
It is 9) and with word number C (value is 3), obtain the first phrase and primary similarity C of the second phrase C；As primary similarity A is
24/29=1/25, primary similarity B is 23/29=1/26, primary similarity C is 23/29=1/26。
Finally according to primary similarity A, primary similarity B, primary similarity C and the second phrase number, calculate three primary
The meansigma methods of similarity, this meansigma methods is the comparison similarity treating sharing video frequency filename with listed files, as the most similar
Degree=(1/25+1/26+1/26)/3=1/48.
In the present embodiment, according to the second phrase number treated in the first word number of sharing video frequency, list of file names and institute
Have the same word number of correspondence, calculate compare similarity provide a kind of simple, feasible, compare Similarity Measure accurately and calculate
Method, improves the accuracy judging to treat sharing video frequency whether upload server further.
Further, on the basis of intelligent television video sharing method first embodiment of the present invention, intelligent television is proposed
Video sharing method the 4th embodiment, with reference to Fig. 5, in the fourth embodiment, step S30 includes:
Step S31, if comparing similarity less than similarity threshold, obtaining current time, treating the video duration of sharing video frequency
With video file size；
Step S32, according to comparing similarity, current time, video duration and video file size, obtains and treats sharing video frequency
Right of broadcasting weight values；
Step S33, by right of broadcasting weight values and treat sharing video frequency be packaged into encapsulation program stream receive encapsulation for server
It is ranked up according to broadcasting weight respectively not playing encapsulation program stream and issues according to clooating sequence after program stream.
When comparing similarity less than similarity threshold, show to treat that sharing video frequency there is a possibility that relatively on the server
Little, and then obtain current time, the video duration treating sharing video frequency and video file size, then according to compare similarity, when
Front time, video duration and video file size, obtain the right of broadcasting weight values treating sharing video frequency, wherein compare similarity the highest,
Show to treat sharing video frequency the highest with the video degree of association that other user on server uploads, i.e. show that this treats sharing video frequency more stream
OK, thus compare similarity to play weight be directly proportional；It is the most remote that current time distance presets historical time, shows to treat that sharing video frequency is more
Novelty, thus current time to play weight the most rearward the biggest；Video duration is the longest, shows that the integrity treating sharing video frequency is the highest, therefore
Video duration is directly proportional to playing weight；Video file size is the least, shows that the compression degree treating sharing video frequency is the highest, therefore video
File size is inversely proportional to playing weight.In addition compare shared by similarity, current time, video duration and video file size
Play weight proportion can arrange according to demand.Finally treat the right of broadcasting weight values of sharing video frequency and treat that sharing video frequency is encapsulated in one
Rise, collectively form encapsulation program stream, when server receives this encapsulation program stream comprising right of broadcasting weight values, server according to
Right of broadcasting weight values is to video to be played and has uploaded and does not plays video and play out weighted value descending sort, waits team to be formed
