Abstract
The invention relates to an interactive video-on-demand technology. With the video-on-demand method, a problem of time delay caused by data transmission channel and server occupation in the traditional technology can be solved. The technical key points are as follows: a related frame of a current on-demand frame is analyzed to obtain related data of an adjacent frame of the current frame; the data are obtained and stored locally; and when the data are needed to be displayed, the data are obtained locally. Therefore, the time delay is reduced and the user experience is improved.
Description
Technical field
The present invention relates to a kind of interactive TV program request technology, specific design also realizes a kind of interactive TV on-demand device and method.
Background technology
Television set along with the development of TV tech self in recent years and the development of internet data service start gradually had new development, except providing the one-sided television video of unilaterally watching and browsing that traditional user can only be passive, audio broadcasting service, interactive VOD video and information service can also be provided, and user selectively carries out interactive VOD by various top box of digital machines and realizes video frequency program and watch at any time video frequency program or carry out information inquiry.Program in interactive VOD is normally stored in special video or information service device (conventionally at far-end computer data center or machine room) or Set Top Box local memory.These two kinds of modes respectively have its feature, and far-end server storage mode be owing to will can introducing time delay through transmission line in the middle of from server to user terminal, cause in on-demand process interactive reflection slow, affects user's experience; Local storage can increase user terminal cost, restriction program amount and information amount.
Summary of the invention
The object of the invention is to for existing interactive TV program request mainly by the technology status of real-time VOD and interactive data transmission, provide one to utilize prior art, in the situation that not changing program request Technical Architecture, not changing server architecture and service, use the memory of interactive television terminals itself, the program request picture that pre-stored user may enter, shorten the interaction reaction time delay causing because of circuit question, thereby improve the user's experience of sowing time of interactive TV point.
For realizing above object, the present invention adopts following technical scheme: a kind of data by the adjacent pictures to current display frame in interactive television terminals are obtained in advance and stored in this locality, the interactive TV VOD system of directly obtaining from this locality and showing in the time need to showing, described interactive TV VOD system comprises interactive VOD server, the user interaction television terminal that the data transmission channel of connection vod server and interactive television terminals is connected with interactive VOD server.
Described interactive TV vod server provides the needed Servers-all service of interactive TV program request or part service, including but not limited to user authenticate, service content catalogue, service content etc.This server in the time accepting interactive television terminals request, directly program request picture or the service content itself containing service content catalogue to interactive television terminals transmission package, or indirectly control other servers and complete this task.
Described data transmission channel is used for transmitting mutual control command and the data of vod server and interactive television terminals.
Described interactive television terminals is the equipment that final completing user interactive TV program request action and program broadcast, its form can be cable television digital TV set-top box, telecom operators' interactive set-top box or other form Set Top Box, can be also the all-in-one form that digital TV set-top box and television set (display) are integrated.
The present invention compared with prior art has the following advantages:
(1) improve user and experience, by reducing the time delay of even eliminating far-end interactive service, improved user's experience, make interaction really instant, feasible.
(2) economize on resources, most of program request picture will be stored in this locality, thereby reduce transmitted data on network amount, saving resource.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Brief description of the drawings
Fig. 1 is overall system block diagram of the present invention.
Fig. 2 is the workflow diagram of the interactive VOD system of interactive television terminals of the present invention
Embodiment
By reference to the accompanying drawings, once the present invention is further described.
As shown in Figure 1, a kind of interactive TV VOD system, system comprises interactive VOD server, the user interaction television terminal that the data transmission channel of connection vod server and interactive television terminals is connected with interactive VOD server.
In practical work process, terminal enters after interactive TV program request state, user will be all the time in the face of a program request picture or program broadcast picture, claim that this program request picture is current program request picture, other program request picture that can enter by an operational motion from current program request picture is called adjacent program request picture.
As shown in Figure 2, interactive television terminals is in the time showing current program request picture, system can the current program request picture of automatic analysis adjacent pictures, and automatically store and search this picture in this locality, judge whether the plurality of adjacent pictures has existed in local storage, if certain adjacent pictures has been stored in this locality, process next adjacent pictures, if not, obtain and be stored in local storage from far-end server, until travel through all adjacent pictures.In the time that user operates user terminal and enters next program request picture, the next program request picture that will enter has been stored in the machine, can directly use, and this picture becomes current program request picture, and system repeats above action.
Claims (4)
1. an interactive TV program request technology, it is characterized in that program request picture adjacent pictures to obtain in advance and buffer memory, making program request picture this picture data in the time entering adjacent pictures is to be provided by this locality but not obtain from vod server or other similar service devices, thereby reduce factor data from outside or get and the time delay that produces, improve interactive VOD user and experience.Herein, adjacent pictures be defined as current picture through program request action or repeatedly program request move the picture that can show.
2. the adjacent pictures that interactive TV program request technology according to claim 1 is used is obtained and caching method in advance, it is characterized in that when current picture disply is waited for user's operation, system is resolved current picture, according to analysis result, obtain its adjacent pictures data from far-end vod server or other similar service devices, and be stored in local system storage device wait for shown.
3. the adjacent pictures that interactive TV program request technology according to claim 1 is used is obtained and caching method in advance, it is characterized in that when current picture disply is waited for user's operation, system is resolved current picture, according to analysis result, contrast with this locality stored picture data, to the adjacent pictures of storage not, obtain this adjacent pictures data from far-end vod server or other similar service devices, and be stored in local system storage device wait for shown.
4. the display packing that interactive TV program request technology according to claim 1 is used, it is characterized in that system is in the time showing next picture, first in local storage, search the data by display frame, if can find, directly use, if not, obtained from remote on-demand server or other similar functions server requests, then show.
