Row certain operations, as carried out infrared remote control, program inquiry, Internet video viewing etc..Whole process is server end and visitor
The result that family end has cooperated.
(1) network data is extracted
It is to obtain data from internet that info web extracts, and is got up by scattered information, is managed collectively, this
Process relates to the acquisition of web page source file, the formulation of extracting rule and info web storage three parts and constitutes.For
Different types of information, have also needs to carry out the information extracted the operations such as integration duplicate removal.
Different internet information is extracted, except for the difference that the choosing of web page source, the difference of extracting rule and after extracting
The processing mode of information different.For the information extraction that data source is more single, generally have only to from one or several station
Point extracts, and the information redundance extracted is the highest, and major part all processes without duplicate removal can be stored in database, this type
Fewer.On internet all there is redundancy in most information, and identical information can occur in multiple different website,
And difference station data form is possible different, the when of therefore extracting information processing, need to consider duplicate removal, and formulation unification
Data structure store.Specifically comprise the following steps that
(1.1) web page source file acquisition
The target pages of web page source file is typically to utilize web crawlers to acquire, and the acquisition of web page source file can approximate
Regarding the process that html file is downloaded as, be different from common file download, this process needs the coding in view of information
Mode and whether have compression.
The page coded system of different web sites is different, and current has GBK, UTF-8, GBK2312 etc..Due to information extraction
Environment coding is fixing, usually ASCII or UTF-8, if it is different to extract page coded system, then the information extracted will
Being that mess code shows, this will be unfavorable for the extraction of file, therefore need to judge webpage during extracting, webpage
Coded system typically judged by the charset field of the meta label of page source file.
Number of site takes the mode of compression to reduce page-size, improves page loading velocity, for this kind of page, under
What load program got is usually compressed file, it is impossible to read internal data.At present frequently with compress mode be gzip,
For this kind of website, then utilize third party library first it to be decompressed, then read data and call for other modules.
(1.2) TV guide is extracted
Programme distant information is different from general information, and the TV guide in each week is fixing, and namely information is total
Amount is certain, and therefore during extracting, to choose a good website the most extremely important, and special for its information
Property, it is not necessary that go multiple website collection, only need to find a more complete website of information and gather.TV guide
Information extraction is as shown in Figure 4.During beginning, it is loaded into local channel information table, reads a line every time, the information read is entered
Row processes, and synthesizes the schedule information page of every day in a week, resolves, the information of extraction is carried out pre-place after download
Reason, mainly removes some spaces etc., then input database, if local channel information table reads complete, then and program knot
Bundle.
(1.3) network video information extracts
Network video information extracts substantially that flow process is as shown in Figure 5.Have multiple owing to network video information extracts website, and many
The composition of individual web video information is not quite similar, but is substantially summed up and includes three parts, i.e. video self-information,
Video classification information and video creation information.Video self-information generally comprises video title, video presentation and video mark
Sign three parts.Video classification information generally comprises subordinate channel, visual classification and affiliated special edition, this type of letter of different web sites
Breath is slightly different.Video creation information includes video uploader information and video uplink time.In view of extracting data to the greatest extent
Possible comprises, and information of therefore extracting includes three category informations:
A) video essential information: include video title, video presentation information and video tab information；
B) video classification information: include special edition belonging to video subordinate channel, visual classification and video；
C) video creation information: include video uploader information and video uplink time.
Different video Website page data organizational form is different, it is therefore necessary to each website is formulated extracting rule, extracts rule
Formulating generally by analyzing what video playback page source file obtained then, believes according to different classes of information labels and description
Breath, judges whether information is category information herein.The description keyword of such as title typically has title, video information
Describe keyword and typically have description etc..For some websites, the different classes of page of the different times page is also possible to deposit
In difference, this must go to adjust dynamically during extracting.Therefore, also need to consider during formulating extracting rule
Some special circumstances, so that the information of extraction is the most accurate.
(2) cloud service interface realizes
(2.1) video true address extraction module
Owing to the video true address of video website is all through encryption, it is so to prevent from directly downloading.Video net
The video true address deciphering rule stood, being the most all embedded in the flash player of website, regarding if playing different web sites
Frequency removes to call different players, and such Consumer's Experience can be bad.So acquisition Internet video true address must be analyzed,
Play online realizing the unification of Internet video client.
Video true address is all encrypted by each big video website, and encryption rule is different, it is therefore necessary to respectively
Individual video website formulates different acquisition modes.The most conventional video true address extracting mode has two kinds, and the first is
Analyze source code and the AES of video web-pages, show that the true address of video, the advantage of this mode are that resolution speed is fast,
It is obtained in that video details, but does not have versatility, and it is complicated to analyze process.
(2.2) TV guide enquiry module
Programme distant information is different from network video information, and it has real-time and the factor such as total amount is little, again due to system
In the mode called have multiple, the most do not take the retrieval mode of traditional search engines, but directly utilize database
Build query interface.During inquiry, Android client can send the inquiry request of subsidiary parameter to server, mesh
Front query argument includes two parts, i.e. searching keyword and inquiry mode.Searching keyword is the keyword of program search,
Inquiry mode is then to inquire about in which way, has three kinds of inquiry modes in system, and one is according to keyword query, second
Planting is that inquiry current time plays TV guide, and the third is the TV guide of one program channel current week of inquiry.Joint
It is as follows that substantially step is inquired about in mesh advance notice:
1. extract query argument.Request to Android client resolves, and obtains searching keyword and inquiry mode two
Keyword, and searching keyword is pre-processed；
2. judge whether searching keyword is empty, the most then judge whether inquiry mode keyword is c, the most then look into
Asking the programme information that current slot broadcasts, sequentially in time, return XML file is to Android client, otherwise
EP (end of program).
3. if searching keyword is not empty, then judging inquiry mode, if s, then inquiry comprises the programme information of keyword,
And temporally return to client；If a, then judge whether searching keyword is channel designation, if then returning this frequency
All programme distant informations of road current week, and return to Android client in chronological order, if it is otherwise, program
Terminate.
(2.3) Internet video enquiry module
The inquiry of Internet video includes that Internet video inquiry and TV guide associated video are recommended, owing to program is recommended to use
Content-based recommendation mode, therefore program is recommended to regard the Internet video inquiry that keyword is programme information as.Net
The step of network query video includes pre-processing keyword, to keyword participle, search index, arrange result
Sequence, the return several part of video information XML file.
1. keyword pretreatment.The characters such as this process is to be removed the useless character in keyword, such as space,
Prevent from affecting Search Results.
2. keyword participle.An one long section sentence is divided into single word, including Chinese word segmentation and English string segmentation by participle exactly
Two kinds.English string segmentation is on the basis of space, fairly simple.Chinese word segmentation is then that a Chinese character sequence is cut into one
Individual single vocabulary, uses forward based on dictionary air exercise matching algorithm to carry out participle in system.
3. search index.This process actually includes two processes.When network video information grabs this from internet
During ground, video information can be indexed operation, utilize Lucene to set up inverted index.When the process of inquiry,
Index is inquired about by the Retrieval Interface then utilizing Solr.
4. pair result is ranked up.This process uses the sort result of Solr, is usually according to keyword degree of correlation
It is ranked up.
5. information returns.Video owing to retrieving is video ID, therefore needs to inquire about database, it is thus achieved that detailed video letter
Breath, according to display content, generates XML file.
(2.4) authentication module
Authentication i.e. subscriber authentication relevant portion, registers including user, user logs in, password gives for change.Consider
The factor such as network security, also password encryption and decryption portion up till now.
1. password encryption deciphering
Owing to present internet industry is more flourishing, because factors such as interests, occur in that much steal user profile illegal point
Son, and the accounts information of website is typically stored on server database, if User Information Database is obtained by lawless person
Take, huge loss will be caused in website and user.Therefore to avoid the generation of this type of thing, it is right to take in system
Password is encrypted measure, even if therefore database is cracked by lawless person, also cannot obtain user cipher.
First cryptographic process needs to pre-process password string, judges after removing head and the tail space, if not empty,
Then call correlation function storehouse and password string is carried out md5 encryption, the string obtained after encryption is returned.Deciphering be exactly one inverse
Process, calls decryption function and carries out MD5 deciphering, is returned by the password string obtained.
2. user's registration
The operating process of user's registration actually database, will user profile store in database, Bu Guo
Before storage, related data need to be pre-processed, including information pre-processing, judge whether user name exists, to password
It is encrypted storage etc..Wherein information pre-processing includes removing some garbages, such as, remove the first space.Judge to use
Whether name in an account book exists, and needs to inquire about database manipulation.It externally has two interfaces, and whether one exist for user name, and one
Individual for user's registration interface.
3. user logs in
User login information actually can regard as one inquiry data manipulation, user name is verified with password, if with number
Relevant information is then returned according to information matches in user information database in storehouse.This process includes the pretreatment to information and password
Md5 encryption two parts.It is then to reduce data base querying number of times that password carries out md5 encryption.
4. password is given for change
Password is given for change with user logs in similar, is the operation of an inquiry database, to user name, password protection problem and close
Protect answer checking, if with information match in user information database, then return to user cipher.
(3) SmartClient realizes
As user operation terminal part, Android client provides the various interfaces of user oriented operation, such as log in,
Registration, remote control, inquiry etc..The design quality of client end interface directly affects Consumer's Experience, and therefore design must be rationally.
A client logic functional module part relies on remote server and realizes, and a part is provided by own module and realizes, and is
Unite and cooperate between each module, client and server common operational, constitute whole intelligent remote control system.
Whole client end interface designs as shown in Figure 6, and one is designed good operation interface and can bring to user different
Experiencing, Android client interface includes five major parts, i.e. initializes interface, authentication related interfaces, client
Main body interface, TV guide related interfaces and Internet video related interfaces.Various piece is assembled with function, and respectively one
Entirety, five major parts join together to form whole intelligent distant control client.Many scenes infrared remote-control operation interface is available for user
The remote control scene selected has default, video display, music and four kinds of patterns of standard, and (a), for presetting remote control interface, (b) is video display
Scene remote control interface, (c) is music scenario remote control interface, and (d) is standard remote interface.
The inside of client realizes depending on what the cooperation of each functional module completed, and functional module is as Android client
Logic realization part, can be divided into five major part, including Equipment Inspection module, authentication module, infrared remote control merit
Energy module, network transmission module and data operation modules.Modules contains again the functional unit of a lot of segmentation, as
Shown in Fig. 7.
(3.1) Equipment Inspection module
Equipment Inspection module application, at the initial phase of equipment, is run due to client and is needed network, external storage card etc.
The support of some equipment, therefore when equipment starts, whether this module meeting detecting system related hardware exists, equipment state
Whether reach demand etc..
1.SD card detects
Client operation generation information and backup and reduction operation etc. are required for place and deposit, and in program, acquiescence leaves in external
On SD card, program can detect whether equipment has external storage card, if it is not, user ID etc. can be reminded when running
Operation may be failed.
2. network detection
Network detection includes many-side, and whether whether equipment has relevant device, and can network, the type etc. of networking.Inspection
The type action surveying networking is to remind user, and some operation may expend very much flow, if if using SIM online,
Should be noted that operation.
(3.2) authentication module
Authentication is the module of a cooperation, needs to use network transmission module, and user logs in, user registers and close
Code gives the process that can regard an information on the client as change.It is sent to server end by gathering relevant information, right
The result that server returns judges, does next step operation.Wherein user log-in block also may require that data operation modules
Cooperation, to the most logged account, client has record, can provide prompting when user operates again, helps user
Rapidly input account number, save user time.
(3.3) function of infrared remote control module
Function of infrared remote control module relates to bluetooth transceiving data and JNI interface realizes two parts.Bluetooth transceiving data is
The less radio-frequency function that android system is supported, mainly turns infrared repeater with bluetooth herein and interacts.JNI interface
Write, then be that the data to Bluetooth receptions process.
1. bluetooth transceiving data
Owing to android system gives tacit consent to the infrared driving of non-burning, so mobile terminal based on Android is to receive and dispatch
Infrared data, the most also cannot the direct infrared home equipment of remote control.All prop up in view of mobile terminal based on Android
Hold Bluetooth function, so for the realization of RTV remote television playing function, taking mobile terminal to turn infrared repeater to bluetooth and send out
Send Bluetooth command, bluetooth to turn infrared repeater the blue-teeth data received is processed, then send infrared command remote control
The method televised.
2.JNI interface realizes
The abbreviation of JNI i.e. Java Native Interface, it can allow Java code interact with the code of other language.
The purpose of its design is the form allowing other codes can be written as dynamic base, calls for Java, due to Android program
Application is Java language, and the data processing module that C language to be called is write is not all right, it is necessary to utilize JNI
Data processing module is packaged into dynamic base, quotes in Android program.Data processing module herein is to move
The infrared remote control command study stage is called by terminal, and detailed process is: mobile terminal turns to bluetooth first with Bluetooth function
Infrared repeater sends study order, guides repeater to gather the infrared control order of infrared home equipment, then repeater
The data separate Bluetooth function collected is sent back mobile terminal, and mobile terminal is adjusted after receiving the data that repeater is beamed back
By dynamic base packaged for JNI data processed and preserve.The data i.e. mobile terminal preserved is for the infrared family of remote control
Turn, to bluetooth, the order that infrared repeater sends when occupying equipment.
(3.4) data operation modules
Data manipulation is one of nucleus module of client, and other module sections the most all have invoked data operation modules.System
Middle data operation modules includes four parts, i.e. local data base operation, common file operations, XML resolve operation and
SharePreferences file operation.
1. local SQLite database manipulation
At the running of client, a lot of relatively well-regulated data, for example user login information, user can be produced
Query Information etc..If using plain text form, reading and condition query all can be cumbersome, if storage is to remotely
On server database, network overhead can increase, and these data are the most not necessarily.Therefore use SQLite this
The database of lightweight, it designs for embedded environment, it is possible to operate on development board, and it is the least to take resource,
Support conventional SQL statement etc..The information of storage is the data produced during certain operations, and the login including user is believed
Breath, user's program inquiry, Internet video search keyword information etc..The operation related to is mainly reading and writing data.
2.XML resolves
XML resolves the most common, no exception in Android.Android platform is commonly used
XML parser has SAX parser, DOM parser and PULL resolver three kinds.SAX parser be a kind of based on
The resolver of event, its advantage is that resolution speed is fast, it is less to take resource.DOM parser is based on tree structure
The resolver of the set of node or information segment, due to DOM in internal memory with tree structure store, therefore retrieval and more
New efficiency can be higher.But for bigger file, load and parsing can compare cost source.The operation of PULL resolver
Mode is similar with SAX, is pattern based on event, and its advantage is that small volume and less weight, resolution speed are fast, easy to use.
SAX parser is used to complete the parsing of XML document, in the data of regularization being stored in by parsing in systems
In depositing, call for other modules.
3. common file operations
Common file operations includes file read-write, compresses, decompresses and copy.It is standby that these operations are mainly used for system
Part reduction.Program operation information in mobile phone can be saved on external SD card by system backup operation, and by these files
Pack, upload onto the server on.System reducing operation is then to be downloaded by the compressed file on server, decompression
Contracting, is then copied in mobile phone.
4.SharePreferences file operation
SharePreferences is a kind of storage mode that Android provides, and is to store key assignments data based on XML file
, it is particularly well-suited to the preservation of software configuration parameter.It is used in systems store some personal settings information.Android
System provides SharedPreferences class to carry out the operation of SharePreferences file.
