Description
Technical field
The present invention relates to the IPTV business field, particularly relate to the apparatus and method that improve the electronic program guides display speed.
Background technology
IPTV is an IPTV, is a kind of broadband cabled television network that utilizes, and integrates multiple technologies such as the Internet, multimedia, communication, and the brand-new technology of the multiple interactive services that comprises Digital Television is provided to the domestic consumer.Digital Television just is meant that all being to use digital television signal or this is installed all signal propagation to all links of emission, transmission, reception from the studio all is to propagate by the digital stream that is made of 0,1 numeric string.IPTV is a telecommunications basic business towards several hundred million families, is a kind of complete new experience of television culture, is terminal with STB+TV (set-top box+TV) mainly at present, and high-quality broadcasting and demand (telecommunication) service are provided simultaneously.EPG (Electronic Program Guide) electronic program guides is a kind of interactive application, its major function is that all digital television programs are combined by different classifying ruless, the user just can check by remote controller, also can be directly switch to from EPG in the in progress program and go.Electronic program guides provides easy-to-use, friendly interface, a mode that can the fast access program to the user, and the user can also watch one or more channels by this function, even all channels are in the recent period with the program of playing.Simultaneously, EPG can provide classification feature, can help the user to browse and selects various types of programs.The role that EPG is born in entire I PTV solution is exactly the portal as IPTV, for the user shows abundant service resources, attracts user's eyeball.If user's a operation, EPG does not respond for a long time, will inevitably make user's experience effect reduce greatly so.Therefore, the operation that how to respond the user fast just becomes one of primary problem that solves of EPG.
EPG mainly exists in two ways at present:
A kind of mode is that EPG depends on set-top box, displayed page is integrated among the hardware of set-top box, and set-top box and background data base are mutual with a protocol software, and set-top box is obtained data from background data base, shows on set-top box then.The shortcoming of this mode is: after displayed page is integrated into set-top box, set-top box must arrive background data base and obtain data, be cached to set-top box then, under present technology and cost downforce, set-top box is difficult to a large amount of hardware resources and preserves data resource, though cause the EPG response speed fast, the film quantity that can support is not enough, generally in thousand.
Another mode is that EPG exists as an independently outside WEB website, and set-top box visits EPG by the form of accessed web page, uses the EPG service, and EPG software dynamically fetches data from database read and shows.Controller referring to device shown in Figure 1: EPG fetches data from database read, is submitted to the page and shows.The information exhibition flow process of this mode is referring to shown in Figure 2: the page of user capture EPG, the page be to the background controller request msg, and the controller reading database after data read come out, is given the page and shown.The shortcoming of this mode is: by the EPG of software mode existence, EPG independently is installed to above the PC server, when the user uses, obtain data resource from database dynamically, data capacity does not have problems, but brought the another one problem, be exactly under the situation of large user's amount, EPG can adopt trunking mode that service is provided, number cover even tens of cover EPG up to a hundred be accessing database simultaneously, can cause great pressure to database manipulation, cause access of database speed to reduce, even cause the database machine of delaying.If avoid this problem, can bring the significantly rising of cost again by the data-base cluster technology.

Embodiment
Main thought of the present invention is to use for reference the metadata cache technology of the integrated EPG of top-set hardware, adopts software EPG implementation.
Embodiment one:
Referring to shown in Figure 3:
Between EPG controller and database, add an EPG data buffer, carry out the buffer memory of data in the database specially, when the EPG device starts, disposable with data read to buffer memory, development with present Web TV, the IPTV business that general provincial operator founds, database resource is generally 2 to 30,000 video display resources, the shared cache resources of video display resource is approximately 2K, even consider follow-up development like this, 100,000 video display resources of buffer memory also only need the memory headroom of 200M, with present PC hardware of server condition, can bear fully.
The disposable internal memory that reads in of data message, when the data message in the database changes, the solution that the information synchronization of buffer memory is upgraded:
For the IPTV business solution, database changes all in the database are all undertaken by the SMS business management system, what comprise all video display resources increases, deletes, changes, looks into operation, between SMS and EPG data buffer, set up a connection, when SMS operates the information of database, just send a piece of news synchronization notice EPG, after the notified message of EPG data buffer, promptly carry out data cached refreshing.
EPG information exhibition flow process increases a data buffer referring to shown in Figure 4 in the present embodiment between EPG controller and database, adopts the operating process of caching technology:
When at first being the startup of EPG device, data buffer is cached to database data in the internal memory; The page of user capture EPG, the page is to the background controller request msg; Controller is submitted to the page with data and is shown directly to the data buffer request msg; SMS more can send a notification message to data buffer in the new database; After the notified message of data buffer, upgrade data cached synchronously.
The present embodiment need not to increase under the situation of any hardware cost, can realize the quick response of EPG; Because metadata cache has arrived internal memory, unusual even database takes place, also can provide service for the user with data in buffer, up to database recovery, the service disconnection risk of having avoided database to bring unusually.
Embodiment two:
On the basis that does not increase hardware cost, can adopt the technology of page cache to improve the EPG response speed.Because different users selects identical data most probably, does identical operations, resulting page data is the same, the user in front can be done the page data buffer memory that certain operation obtains like this gets off, if the back has other users to do same operation, just without Query Database, but directly the information of buffer memory is shown to the user; If the database information change, SMS empties the information of buffer memory with regard to notifying EPG, carries out buffer memory again.
Specific practice is as follows:
Referring to shown in Figure 5: in the device of EPG, by controller directly and database carry out alternately, after the data that controller reads are submitted to page display, be not to abandon at once, but with this metadata cache in data buffer, the database caches device is managed by controller.
Controller at first checked whether comprised desired data in the data buffer before reading database extracts data, if exist, then do not carry out database manipulation, directly the information of buffer memory in the data buffer was submitted to page display.
When SMS operation such as increases, deletes, changes, looks into to database, directly notify the EPG controller to remove institute's data in buffer, the buffer memory of data carries out again.
The information flow of present embodiment is as follows, with reference to Fig. 6:
Page display is to the controller request msg; The data of controller reading database are submitted to page display with the data that read, and with this metadata cache in data buffer; During request msg, controller at first checks whether comprised desired data in the data buffer to page display once more, if exist, does not then carry out database manipulation, directly the information of buffer memory in the data buffer is submitted to page display; If there is no, controller is the data of reading database again, submit to page display, and with this metadata cache in data buffer.When SMS operation such as increases, deletes, changes, looks into to database, directly notify the EPG controller to remove institute's data in buffer, the buffer memory of data carries out again.
Data cached in the present embodiment is dynamically to increase, and is some data that the user uses always basically, controller to the hit rate of inquiry than higher.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
