Embodiment
Please, be the flow chart of first embodiment of the invention referring to Fig. 1.This embodiment is given in and carries out the method that index information sends in the unidirectional network, and this embodiment specifically is used for a unidirectional network video on-demand system, is sent the index information of video frequency request program to terminal by server.
Step S101 introduces program the page formatting information of the page and separates with effective information.
In the present embodiment, the index information of this VOD system adopts HTML(Hypertext Markup Language), writes down and organize index information with page format.The described page comprises that catalogue homepage, the classified catalogue page, program introduce the page.Described catalogue homepage is mainly used in the classified catalogue page that exists in this VOD system programme content of record.In this catalogue homepage, pass through on-link mode (OLM).Can enter the classified catalogue page; In the described classified catalogue page, record the catalogue of the concrete program that belongs to this classification, can enter concrete program by this catalogue and introduce the page.Because each program is introduced the page and is all comprised a large amount of format informations, and its format information is identical.Therefore, the format information that program can be introduced the page extracts, and forms the page template surface information.
Described effective information comprises the IP address of background support server, the IP address of video server, service name (service name), type of service (service type), program code (offering ID) etc.For each page, effective information all has nothing in common with each other.But the content of effective information is also few, and the effective information of each page is roughly about the 300-500 byte.
Step S102, the page that will have same format information forms unified page template surface information.
In described page formatting information, comprise the information of all form aspects that form this page.In the index information of VOD system, each program is introduced the page can have unified display format, like this, just only need a template page to get final product, still, also may have several different demonstrations various by program lobby page mask, in this case, form several template pages possibly.
Step S103 adds the uniform resource locator sign in above-mentioned page template surface information.
Described page template surface information identifies by uniform resource locator, so that inquiry obtains.Owing to adopt HTML to form the page, therefore, can be that each template page adds the uniform resource locator sign easily.
Step S104, the uniform resource locator that adds corresponding template in described effective information identifies.
The correct demonstration of ability because effective information must match with the template corresponding page by add the uniform resource locator sign of the template corresponding page in effective information, just can obtain its corresponding template page from this effective information.
Step S105 with information relevant with certain concrete program in the effective information, is embedded into the relevant classified catalogue page and records in the project of this program.
Because each classified catalogue page records corresponding to each recording of programs project under this classification.The title of this program of record and chained address etc. in this project, if the effective information of directly program of related-program being introduced in the page adds transmission together in this record entry, then can simplify the process of transmission, and be convenient to find corresponding program to introduce the page.The described classified catalogue page is lower floor's classified catalogue page, also has the classified catalogue page on some upper stratas, is used to provide the link of pointing to each lower floor's classified catalogue page.The classified catalogue page on these upper stratas adopts normal mode to send in the present embodiment.Certainly, also can adopt the mode that format information and Template Information are separated to send the classified catalogue page.
Step S106 issues described page template surface information with the forms of broadcasting, and effective information.Wherein effective information is introduced the classified catalogue page of page effective information and is sent by the described program that comprises.
Because in each top step, program having been introduced the page formatting information of the page separates with effective information, and the same page format information formed the unified template page, like this, during broadcasting, every class page is only with broadcasting a template page, and identical page formatting information need not be broadcast in the different pages repeatedly.
Effective information is the information that each page is different from other pages, because the byte that the effective information in each page takies is limited, therefore, each page only need extract a spot of effective information, just can obtain the enough information relevant with this program.Because the effective information of introducing the page of each program has embedded in the relevant record of respective classified catalog page, therefore, as long as send the classified catalogue page, the program that just can obtain all programs of this classification is introduced the effective information of the page.
The form that above-mentioned broadcasting process adopts the circulation wheel to broadcast sends repeatedly at the specific channel of unidirectional network.During taking turns, each all broadcasts the template page info one time.
Owing to adopted above-mentioned index information send mode, make the format information of program lobby page face be reduced to every only the wheel and send once, data volume will significantly reduce.Simultaneously, the quantity that sends the page also significantly reduces.
For example, originally the amount of information of each page was 5Kbyte, had 3000 programs and introduced the page, the classified catalogue page of 100 higher levels and 300 lower floor's classified catalogue pages of showing concrete program.Always be exactly the informational needs of total 17Mbyte (136Mbit) sends.In one-way broadcasting network, adopt dedicated channel to send index information, the per second traffic volume is 38Mbit, then needs all information wheels were broadcast one time in 3.58 seconds.
Now, the data volume in the classified catalogue page approximately be increased to 8Kbyte, and overall page number reduces to 400 owing to embedded program and introduce the effective information of the page and increase to some extent, and total amount of data just approximately is like this: 5*100+8*300=2.9Mbyte.Under the then same transmission speed, only need just can take turns in 0.61 second and broadcast once.
As seen, by above-mentioned measure, can significantly reduce volume of transmitted data.
The index information sending method of the unidirectional network VOD that proposes at the foregoing description, second embodiment of the invention provides the method for reseptance of index information in a kind of unidirectional network broadcast system.This method is particularly useful for the video on-demand system based on unidirectional network, and its prerequisite is in unidirectional network, provides the server of index information to adopt the method for above-mentioned first embodiment to send index information.Present embodiment is an example with the index information in the video on-demand system that adopts set-top box reception unidirectional network, and in fact, this method also can be used for adopting other-end to receive the index information of the broadcast message of various unidirectional networks.
Step S201 receives the index information of broadcasting in the network.
Specific channel in network, server is broadcast index information by the broadcast mode circulation, and this index information comprises the page template surface information, and effective information.

Wherein, the program effective information of introducing the page has been embedded in the project of this program of record in the relevant classified catalogue page effective information.In each catalog classification page, can obtain the effective information that corresponding program is introduced the page.And each program is introduced in the effective information of the page, comprises the uniform resource locator address of its corresponding template page again, can find the relevant page by this effective information.
Step S202 shows the master catalogue page.
The described master catalogue page is the catalogue of index information, by this page, can obtain the direct or indirect chained address of leading to other pages.For example, the address of some classified catalogue pages can be obtained to be linked to, the address that concrete program in such is introduced the page can be obtained again by the classified catalogue page by the master catalogue page.Because all index informations are to adopt HTML record and tissue, therefore, each page can be inquired about by on-link mode (OLM).
Step S203 determines the classified catalogue page of its needs according to user's selection.
The user can determine the own required classified catalogue page that enters by the described master catalogue page, and this information is sent to set-top box, after set-top box is known the required classified catalogue page of user, can obtain the chained address of this page by the master catalogue page.And enter this classified catalogue page.
Step S204 receives user selected program, reads the effective information of this page.
Because the effective information that all programs are introduced the page has embedded in the respective directories item of respective classified catalog page, can introduce the effective information of the page by the program that this directory entry directly obtains this program correspondence.
Step S205, the address of reading the template page that comprises in the effective information that is obtained.
Each group effective information belongs to a display page, because the effective information that these group data are this page, therefore, only obtaining this information can't normally show.For this reason, set-top box reads the template page address that comprises in this group effective information, to obtain the template page that this group effective information comprises.Described template page address is adopted the uniform resource locator address in the present embodiment.In fact, also can adopt other address designation method location.
Step S206 reads the relevant template page according to the address of the described template page.
According to the template page address that comprises in the described effective information, find the page template surface information at the index information of described loop play, and read this page template surface information.Described page template surface information is whenever taken turns transmission and all can be occurred in the index information process of transmitting, and therefore, set-top box needs to wait for one-period at most, just can obtain this page template surface information.
Step S207 inserts the template page with effective information.
Obtained required effective information by above-mentioned steps, and the template corresponding page info.Above-mentioned effective information is organized according to the call format that comprises in the page template surface information, just can be realized effective information is inserted the template page.
Step S208 shows complete index pages.
After effective information inserted the template corresponding page, can on display, show this page.
Step S209, reception user's selection information.
The purpose of display page is that whether introduce page decision according to this program selects this program, therefore, receive user's selection.
Step S210 judges whether the user selects the program of current page; If then enter step S212; If not, then enter step S213.
Step S211, set-top box reads the program code in the effective information information.
In the present embodiment, the program of described demonstration is introduced not display program numbering of the page.But this program code exists in this program is introduced the effective information of the page, in case the user selects this program, then set-top box can obtain described program code from the effective information that has read.
Step S212, the display program numbering.
After showing this program code, the user can handle in view of the above accordingly, for example, orders this program by mobile phone short server.
Step S213 returns the homepage or the upper strata classified catalogue page according to user's indication.
The embodiment that the above-mentioned index information that is based on the video on-demand system of unidirectional network transmits, in fact, this mode can be used for various one-way broadcasting networks to the volume of transmitted data sensitivity and transmit the information with same format.
In the above-described embodiments, according to specific circumstances, the effective information of program being introduced the page is embedded in the respective classified catalog page.In fact, also can be directly the effective information of each page be transmitted as one group of data.
In the above-described embodiments, only program is introduced the mode that the page adopts format information to separate with effective information and transmit,, also can all adopt this mode to transmit, so that reduce the data conveying capacity to greatest extent in other occasions.
In a word, core concept of the present invention is, the format information that repeats in a large number under the prior art to send is extracted as the page template surface information, only sends once.Adopt the mode of effective information being inserted Template Information at receiving terminal, obtain complete display page.By this kind mode, significantly reduced the data conveying capacity, adopt the wheel broadcast mode broadcast format occasion of the format informations of repetition in a large number for needs, this method has the good technical effect.
