Digital Television exempts from the method for program searchingTechnical field
The present invention relates to Digital Television, particularly the program acquisition method of Digital Television.
Background technology
Along with the raising of the growing of science and technology and people's living standard, Digital Television comes into the life of huge numbers of families just fast, and in China, Digital Television is popularized just gradually.Digital Television is based on condition receiving system and CA system, provides TV service by digital-TV operator by TV network to user.At present, there is corresponding digital-TV operator (broadcasting and TV) all parts of the country almost each area, and the program that each operator provides can be different.Generally, after user buys TV, when using for the first time, first local operator is selected, then carry out program searching, the program searching mode that TV control system can be selected according to user, from some frequencies, frequency carries out program searching one by one, often search a program, relevant programme information to be saved in system program list and can not to lose programme information because of power down by system.After having searched for whole programs that operator in network provides, system has exited search automatically, starts broadcast program.Afterwards, user uses at every turn and need not carry out program searching again, and the programme information in TV control system meeting Automatically invoked the rendition list carries out program broadcasting.But in user's factory reset or under changing the situations such as operator, the programme information preserved in TV control system meeting clearing systems, needing to re-start program searching could watch program.The digital television program amount carried due to TV network is very large, therefore often carries out a program searching, needs to spend considerable time, and this brings inconvenience for user.
Summary of the invention
The object of the invention is in order to solve existing TV when factory reset or change operator need to re-start the problem that program searching could watch program.
The technical scheme that the present invention solves its technical problem is: Digital Television exempts from the method for program searching, and step is as follows:
A. in television system, set up one for preserving the local program information database of programme information, the data in described local program information database are not recovered with power down or system data and are lost;
B. TV is by network Real-time Obtaining programme information be stored in local program information database from television programming provider server, and described television programming provider server comprises TV production firm server and local CHINA RFTCOM Co Ltd server;
C. system obtains programme information and plays from described local program information database.
Particularly, in step B, TV by network from the method for television programming provider server Real-time Obtaining program information data is:
If system is connected with TV production firm server by network, then system obtains programme information from TV production firm server, if system is not connected with TV production firm server, then from local CHINA RFTCOM Co Ltd server, obtains programme information.
Particularly, in step B, the method that system obtains programme information from TV production firm server is:
By being connected with mobile terminal by TV, the geographical location information of the current position of acquisition for mobile terminal also sends to TV, and TV obtains the programme information of corresponding region according to described geographical location information.
The invention has the beneficial effects as follows: by method of the present invention, user can be allowed in first use or under changing the situations such as operator, program searching need not be carried out again.
Embodiment
Below in conjunction with embodiment, technical scheme of the present invention is further described.
The invention provides a kind of method, make digital cable customers in first use or under changing the situations such as operator, program searching need not be carried out again.Set up one in order to preserve the database of this area programme information for each area in systems in which, system is at factory reset or digital cable customers when using for the first time, and the data in database are initialization data.In use, from TV production firm server, download corresponding program information data in database corresponding to this area by network, and be saved in system, and do not lose data with power down.When user watches program, system reads programme information from corresponding database, thus realizes program broadcasting.By such mode, user need not frequency removal search program one by one again, and this greatly facilitates user, improves Product Experience.
Embodiment
With Changhong CHIQ brand TV for row, set up one first in systems in which for preserving the local program information database of programme information, the data in database can not be lost because of system power failure or System recover data.In start guide, select in " Mianyang ", be switched to after under DTV (Digital Television) pattern when system first time, system can eject search guide.After user selects cable TV, at this moment system can eject operator and select dialog box, select " Mianyang broadcasting and TV ", if networked system downloading data from Changhong server automatically afterwards, and save the data in the region corresponding to system database list " Mianyang "; If failed cluster system, searching programs information from the CHINA RFTCOM Co Ltd of Mianyang is also kept in the region corresponding to system database list " general ".
If do not arrange geographical position in start guide, system by the provinces and cities at IP consumer positioning place, and from TV production firm (as Changhong) server, selects the program data information downloading corresponding region.If user skips start guide, " menu " option provided by system is selected to carry out program searching, or user's switch operators, then system downloads the program data information of corresponding region from the local photoelectricity webserver of correspondence by location operator.
In addition, also can be connected in local area network (LAN) by television set and mobile terminal, the geographical location information of the current position of acquisition for mobile terminal also sends to TV, and TV obtains the programme information of corresponding region according to described geographical location information.Local area network (LAN) is set up by wireless router, and the scope of wireless router wireless connections general at present is generally no more than 20 meters, therefore uses the geographical location information of acquisition for mobile terminal can position residing for effecting reaction TV.
