Embodiment

The present invention will be further described below in conjunction with accompanying drawing.

The device of the realization IPTV business that the present invention proposes comprises: EPG system, set-top box, streaming media server, be provided with player, button driver module in the described set-top box, and it is characterized in that, also comprise:

Business function module is arranged in the EPG system, is used for realizing the business function of the various functions of IPTV;

Wherein, described memory module, calling service module, business information storage mould are the subwindow of same browser.

Wherein, described business function module is the JavaScript script.

The design philosophy of the present invention by adopting the service logic control and management to separate with set-top box provides a kind of professional device of realizing fast in network television system.

TV-set top box provides basic software and operation, comprises browser, looks audio player, remote controller key handles and drive etc.Browser is by JavaScript script operation set-top box player, every media play operation such as finish broadcast, time-out, F.F., rewind down, stop.The set-top box button drives button is sent into browser, and after browser JavaScript script received button, according to residing operation flow, the distribution button called different JavaScript script function, finishes service logic control.

In order to reduce to the taking of set-top box internal memory, reduce the set-top box cost, adopt on single browser instances by many frameworks and realize that service logics control.Browser page is divided into two subframe A and B, and wherein subframe A does not show, another subframe B has occupied all viewing areas of browser, and two subframes are shared father's framework P.Browser has been divided into three windows like this, a parent window P, two subwindow A and B.

The P window does not refresh generally speaking, mainly deposit the channel of the channel of channel tabulation, channel link tabulation, last visit, the information such as channel of current channel of visiting, these information only just lost efficacy after the P window refreshes in the medium-term and long-term existence of P window.In order to guarantee the integrality of data, on EPG, backed up the data of a P window, when the P window refreshes, transmit these data from EPG and give the P window, guaranteed that data can not lose.The overall situation functions such as interface that remote controller key is handled function, obtained and be provided with the P window data in the P window, have also been deposited simultaneously.

The A window is responsible for obtaining data from EPG.According to the needs of business function, in the A window, initiate request visit EPG system, data that EPG returns or in the storage of P window, perhaps according in the B window, showing after the function treatment.

The B window is responsible for showing the EPG page.When the user switched to the EPG page, the B window was used for display page; After the user enters video broadcasting condition, can pass through OSD (the translucent wicket of stack on video) and show the EPG page in the appointed area of B window.

Behind the set-top-box opening, browser access EPG system, EPG is responsible for generating page framework, and generates channel tabulation, channel link tabulation in the P window, the channel when current channel number is set to set-top box and shut down last time.After the frame system initialization is finished, show the EPG page or carry out video playback at the B window according to service function requirement by the built-in JavaScript Object Operations set-top box device of browser, at the B window keyboard callback events is installed simultaneously, is received remote keying incident, Streaming Media visit result event, EPG page access result event etc.If event occurs, the B window is according to the incident distribution processor that passes over, and three windows cooperatively interact, and finish the realization of operation flow.Fig. 2 has showed this scheme.

The process of showing video to the user is described below, further specifies the operation principle of device in operation flow of the IPTV business of the present invention's realization.As shown in Figure 3:

The first step, set-top box powers up, device initialize;

In second step, set-top box is by the URL operating browser visit EPG system of the EPG homepage of storage inside;

In the 3rd step, the EPG system sets up user's power cut-off information according to user label: channel, channel link, reproduction time etc. generate page framework;

In the 4th step, the B window is carried out JavaScript script in the EPG page, switches to outage memory channel, calls the JavaScript built-in device and control object in the A window, is initiated to the request of streaming media server, in the P window timer is set simultaneously;

The 5th step, after timer triggers, in the request of B window initiation to EPG, the relevant information of storage current channel;

In the 6th step, after the streaming media server response, set-top box is carried out video playback;

In the 7th step, fitting key disk management dispatching patcher in the B window is taken over the user remote controller button and is handled, and waits for user's operation;

In the 8th step, so far the user can enjoy video display sumptuous meal that IPTV brings.

By the description of above-mentioned operation flow, utilize structurized many frameworks management scheduling system greatly to simplify the operation flow implementation procedure as can be seen, make that IPTV system extension business function is very convenient, have the very strong market competitiveness.
