Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is described.
Terminal in the embodiment of the present invention may include that mobile phone, tablet computer, personal computer, smart television etc. are various
Smart machine.Terminal is available to a feature list.Then according to each single item function in the list, whether judge itself
It can support the function in feature list.And characteristic information is generated according to the result of judgement, characteristic information is used to indicate the end
Whether end meets the various functions in feature list.After terminal generates this feature parameter, the spy can be sent to server
Levy parameter.After server receives this feature parameter, can be determined by characteristic parameter function that the terminal can be supported and
The function that can not be supported, so that will only can send to terminal can support with the terminal when sending data to the terminal
The data that match of function.
For example, when terminal to server requests video data, sending feature to the server in an actual example
Information, server determine that the terminal cannot support multitone rail from this feature information, so that server can be to the terminal
The video data for not containing multitone rail is sent, or after it will reject to partial data corresponding to track in video data, then
It is sent to terminal.The data that can be supported so as to avoid user from manually selecting with own terminal improve user experience.
Referring to Fig. 1, Fig. 1 is the first flow chart of data transmission method provided in an embodiment of the present invention, comprising:
Step 101, terminal obtains feature list, includes the mark of multiple function in the feature list.
Feature list is the listing file or information of a record various functions, wherein the mark of the various functions recorded,
It can be the mark for the various functions that terminal may be supported.The mark of function can be the title of each function, code name or
It is functional parameter, as long as can accurately reflect the function, all can serve as the mark of the function.
For different data type or terminal type, there can be different feature lists.For example, the embodiment of the present invention
When applied to video broadcasting field, feature list can be for shown in table 1.
Table 1
| FLV |
| RMVB |
| WMV |
| Multitone rail |
| Subtitle file |
FLV, RMVB and WMV are three kinds of video formats in table 1, and multitone rail is a kind of format of audio, and subtitle file refers to
The independent individual subtitle file with video data.
Certainly, table 1 is exemplary only lists several Xiang Gongneng, in practical applications, function related with video data
Mark can be recorded in feature list.The corresponding function of mark recorded in table 1 is terminal when carrying out video playing,
The function that can be supported.
When the embodiment of the present invention is applied to other field, function recorded in feature list be can be and the field
Corresponding function.For example, terminal when from server download games, can recorde in feature list it is minimum required for the game
Configuration, or basic function required for the game can be run.
In a field, for different terminal types, there can also be different feature lists, for example, broadcasting in video
Field is put, for mobile phone and smart television, due to its hardware difference, it is possible to there is different feature lists.
Different types of terminal is carrying out different in application, can choose the different feature list of acquisition.
Feature list can safeguard that server can be can be provided according to itself to the data of terminal by server is unified
Situation is updated the feature list, the operation such as adds or deletes, such as video class data, server can only be provided
The video data of tri- kinds of video formats of FLV, RMVB and WMV, then three kinds of video lattice can be added in server in feature list
The mark of formula.Terminal can obtain feature list from server first when needing to obtain corresponding data from server.Alternatively,
Can also preset function list in the terminal, terminal can regularly update the feature list from server.
Step 102, terminal judges whether itself supports the various functions in feature list, and generates characteristic information, feature
Information includes the information for the various functions whether terminal is supported in feature list.
, can be for the mark of each single item function in the feature list after terminal obtains feature list, judgement is certainly
Whether body can support the corresponding function of the mark.
Whether terminal supports that the corresponding function of the mark may include judging whether the hardware of terminal supports the function, and sentence
Whether the software of disconnected terminal supports the function, wherein the software of terminal whether support the function include application program in terminal or
Driver etc., such as media play platform, client software.
For example, terminal may determine that whether itself can play FLV format in feature list shown in table 1, judge whether
The video that RMVB format can be played judges whether the video that can play WMV format, judges whether to support multitone rail, judgement
Whether subtitle file is supported.
Terminal can generate feature according to judging result when judging whether itself supports the various functions in feature list
Information.Characteristic information includes the information for the various functions whether terminal can be supported in the feature list, for notifying server
The terminal those of can support which function in feature list and cannot support in the feature list function.
It, can be to using terminal also, when terminal judges that itself cannot support the core function in feature list
User issues abnormal prompt, wherein core function refers to when not being able to satisfy the function, then can not run and be wanted on the terminal
The data of acquisition.It is exemplified by Table 1, when terminal cannot support these three video formats of FLV, RMVB and WMV simultaneously, then it represents that clothes
Business device, which can be provided these three video formats terminals, can not all support.Exception information can be issued the user at this time, and indicating should
Terminal can not the normal play video to be played.
Characteristic information can be using the existing various information types for communicating between terminal and server, as long as can
It is identified by server, and can enable the server to learn the terminal for feature list, can support and cannot supported
Function.
Step 103, terminal to server sends data acquisition request and characteristic information, and data acquisition request is used for service
Device obtains corresponding data.
In an implementation of the embodiment of the present invention, terminal can to server send data acquisition request when,
Characteristic information is included in the data acquisition request, it is synchronous to be sent to server.
In another implementation of the embodiment of the present invention, terminal can send data acquisition to server first and ask
It asks, and obtains feature list from server, then generate characteristic information, then characteristic information is individually sent to server.
Data acquisition request is used to obtain corresponding data to server, for example, when terminal will play video, Ke Yixiang
Server sends the request for obtaining video data, wherein can contain the mark for the video to be played, server is according to the mark
Know to send to terminal and identifies corresponding video data.
After server receives the data acquisition request and characteristic information, according to characteristic information, determine and the number
It is corresponding according to acquisition request, and the data that the function that can be supported with the terminal matches, and to described in terminal transmission
Data.
Server obtains the characteristic information in data acquisition request, or after the characteristic information individually sent, can be according to this
Characteristic information is determined to match with the function that the terminal can be supported from the corresponding total data of data acquisition request
Data, and send the data to terminal.
Server determines the data to match with the function that the terminal can be supported according to characteristic information, can be from complete
It is rejected in the data in portion, the corresponding partial data of the function which cannot support can also be from the data of plurality of optional,
Select the data that the terminal can be supported.
By taking above-mentioned table 1 as an example, for example, the characteristic information that the terminal to server is sent represents the terminal and can only support
The video data of RMVB format cannot support the video data for playing FLV format and WMV format, cannot support multitone rail, cannot
Support independent subtitle file.After server gets this feature information, then the view of RMVB format can be sent to the server
Frequency evidence, and therefrom remove the related data of multitone rail and the corresponding data of independent subtitle file.So that transmitted data with
The function that terminal can be supported is to matching.
Step 104, terminal receives the data that server is sent.
Terminal can receive data transmitted by server, the function phase which can support with terminal
Match.Can apply the data directly to terminal, not will cause function that data transmitted by server are supported with terminal not
Compatible problem.
In embodiments of the present invention, when terminal obtains data from server, characteristic information can be sent to server, it should
The function that characteristic information can enable server that can determine that the terminal is supported and the function that cannot be supported；And from end
It holds in requested total data, determines that the data that the function that can be supported with the terminal matches are sent to the terminal.From
And it can effectively solve the problems, such as that the data for being directed to different terminals are incompatible, and do not need user and manually select own terminal energy
The data type enough supported improves user experience.
In conjunction with the above embodiments, applying in data transmission method provided in an embodiment of the present invention, in feature list
It may include the mark by the multiple function of preset order record.
Correspondingly, as shown in Fig. 2, terminal judges itself whether support every function in the feature list in step 102
Can, and characteristic information is generated, may include:
Step 102A, terminal judge itself whether support every function in the feature list item by item by the preset order
Energy.
In practical applications, in order to which server more readily will can determine the end from the characteristic information that terminal is sent
The function that end can be supported and can not support.So can be in feature list, by the mark of preset order record multiple function
Know.Preset order refers to putting in order for the mark of each function in feature list, as long as can have determining succession
Arrangement mode all can serve as preset order.
Terminal equally judges whether itself supports the various functions in the feature list by the preset order item by item.
Step 102B, according to judging result, terminal generates character string by the preset order, and the character in the character string is corresponding
The function that corresponding position records in feature list can support function to arrange in the character string using the expression of the first preset characters
Function in table indicates to support the function in feature list using the second preset characters.
Terminal can may include two in character string according to judgement as a result, by the preset order one character string of generation
The different character of kind, respectively the first character and the second character.The first word of each of the character string generated by preset order
Symbol or the second character, indicate whether the terminal can support the function in corresponding feature list on same ordinal position.Wherein,
First character or the second character can be arbitrary character or symbol, as long as server is made to know the first character representation terminal in advance
It can support the function in feature list, the second preset characters indicate to support the function in feature list, to protect
Server is demonstrate,proved when receiving the character string, can clearly parse its meaning.
For example, the mark of each function has natural order in feature list shown in table 1, it is first to be identified as " FLV ", most
The latter is identified as " subtitle file ".Character " a " can be used as the first character in terminal, and " b " is used as the second character.Terminal can
With item by item judge whether itself meets the various functions in feature list.When the video of terminal support FLV format, cannot support
RMVB and WMV format video can support multitone rail, and when cannot support subtitle file, character string generated is then
“abbab”。
Step 102C, terminal is using the character string as characteristic information.
Terminal can send this feature information using the character string with preset order of generation as characteristic information
To server.Server can be determined quickly according to this feature information, and according to the feature list with preset order
The function that the terminal is supported.In embodiments of the present invention, due to using the form of character string as characteristic information, Ke Yiti
While high server efficiency, the function that allows server more accurately to determine that terminal is supported.
In conjunction with the above embodiments, optionally, in data transmission method provided in an embodiment of the present invention, described first is pre-
If character and second preset characters are respectively 1 or 0；
Correspondingly, the character string is binary number.
In computer field, binary number is the character for being easiest to be handled by computer system, and in computer
Middle binary number can be stored by the smallest storage cell bit, so as to largely reduce feature
The data volume of information.
As shown in figure 3, terminal can be by preset order, the mark of the various functions in corresponding function list 301 generates two
System number 302, the total bit of binary number 302 are equal to the mark total item of function in feature list.
Function A in feature list 301 corresponds in binary number 302 first bit；Function B, right in feature list 301
Answer second bit in binary number 302；And so on.And " 1 ", which can be used, indicates that terminal supports this function, uses
" 0 " indicates that terminal does not support this function.
In embodiments of the present invention, use binary number as characteristic information, can reduce the size of characteristic information, be easy to
Network transmission, and more convenient pair of this feature information of server can be made to identify, further increase efficiency.
In conjunction with the above embodiments, optionally, in data transmission method provided in an embodiment of the present invention, terminal will be upper
When stating the character string in embodiment as the characteristic information, the character string of binary number form can be converted into the decimal system
Number；And using the decimal number as characteristic information.
, can be by the character string directly as characteristic information after terminal generates the character string of binary number form, but be
The size of further compression this feature information, and keep this feature information easier and send to server, can should
The character string of binary number form is converted to decimal number.Characteristic information is expressed by way of a parameter,
After server receives the characteristic information of the parametric form, the parameter can be converted to binary number, and then determine the end
Hold the function that can be supported.
In embodiments of the present invention, by converting decimal number for binary number, by characteristic information in the form of parameter
It is transmitted, not only can also be conducive to the transmission of characteristic information with the size of compressive features information, it can be by the parameter shape
The characteristic information of formula is added into all kinds of messages or data packet that server is sent, can be improved characteristic parameter and other information or
The compatibility of instruction.
Optionally, in data transmission method provided in an embodiment of the present invention, terminal judges whether itself supports function to arrange
Various functions in table may include:
Terminal judges the hardware capability of itself, if supports that the various functions in feature list, hardware capability are in terminal
The function that can support of hardware.
The embodiment of the present invention in practical application, in most cases, terminal is unable to support section function, be all due to
Hardware reason causes.When software aspects are unable to support section function, the customer upgrade or more cenotype of prompt terminal can be passed through
The software or program answered, and then it is able to solve the problem of being unable to support section function.However, the hardware capability when terminal cannot prop up
When holding the partial function in feature list, then data from the hardware of the terminal to terminal that can only can be supported by sending come so that
Terminal carries out normal task, such as video playing.
So terminal is when judging whether itself supports the various functions in feature list, judgement itself that can be preferential
Hardware capability, if can support each single item function in feature list, hardware capability includes that each hardware of the terminal can prop up
The function of holding, for example, the data format that the decoder in the terminal can be supported, the highest that display device can be supported is differentiated
Rate, the highest frame number etc. that image processing apparatus can be supported.
In embodiments of the present invention, by preferentially judging whether the hardware capability of terminal itself meets the function in feature list
Can, the judging efficiency of terminal can be improved, quickly judge the function that can be supported and cannot support, and in time to service
Device feedback, can be further improved the efficiency of terminal and server interaction.
Referring to fig. 4, Fig. 4 is the third flow chart of data transmission method provided in an embodiment of the present invention, comprising:
Step 401, the data acquisition request and characteristic information that server receiving terminal is sent, data acquisition request are used for institute
It states terminal to server and obtains corresponding data, characteristic information includes the information for the various functions that the terminal can be supported.
