Description
Technical field
The present invention relates to the digital television techniques field, especially relate to a kind of DTV second screen based on band WIFI focus STB.
Background technology
In the current society,, in each age stratum's life, playing the part of crucial role as family's TV of one of main amusement and recreation form.Undoubtedly; Development along with technology of all kinds; The function of TV is all the more powerful and extensive; Especially wherein abundant digital television broadcasting program, internet surfing, online receiving and dispatching mail, ecommerce, music experience, long-distance education, video conference or the like function, more and more important role is played the part of in beginning in people's life, and progressively life that is improving people and idea.
As basis and the prerequisite that these functions realize, band WIFI focus STB is indispensable.As its name suggests, STB refers to the box on the television set top, is a kind of household electrical appliances of expansion television set function.STB is divided into analog set top and top box of digital machine according to the signal kinds that receives.Analog set top receives analog signal, top box of digital machine receiving digital signals.STB (STB) is not only user terminal; It also is the network terminal; It utilizes cable TV network as transmission platform; Television set is as user terminal, and it can make simulated television turn to interactive digital TV from passive reception simulated television, makes the user enjoy omnibearing information services such as DTV, data broadcasting.It gradually improvement and simplifying television set, make television set independent with reduction for as just display screen.The STB of wireless network card is being set, and STB can also provide the wifi focus except the function that can accomplish general STB completion, supplies panel computer (pad) to carry out wireless connections.Simultaneously, the digital television broadcasting program that receives in the STB can send pad to through wifi.
Along with the propelling and the enforcement of integration of three networks industry, the function of STB will be become stronger day by day, and it will be one " a highly integrated small intelligent computer ".Therefore, it is not an ordinary electrical home appliance equipment, and develops into the family information center, is the gateway that connects family's sub-network and social macroreticular.Under such background, then need seek a kind of more flexible and user-friendly operating means, to realize the intelligent interaction between user and DTV and the STB.When the user gets into the bedroom; Do not want to watch television screen but still want to see digital television program, insert the Internet, receiving and dispatching mail etc.; The tradition interactive mode can't satisfy such demand far away, be badly in need of to seek a kind of convenient, simple and direct, hommization, flexibility, intelligentized interaction schemes.
Summary of the invention
To the interaction technique means defective and the deficiency that exist in the current digit TV, the invention provides a kind of DTV second screen based on band WIFI focus STB.
Technical scheme of the present invention is a kind of DTV second screen based on band WIFI focus STB, adopts the intelligent end device of band touch-screen, comprises in the intelligent end device:
The digital television program receiver module is used for receiving audio, video data from band WIFI focus STB;
The digital television program parsing module is used for the audio, video data that the digital television program receiver module receives is resolved, and obtains the audio/video flow of digital television program, calls player and plays.
And, remote control module is set, be used for the control touch event of monitoring users, the corresponding key sign indicating number is sent to band WIFI focus STB with wireless mode.
And said intelligent terminal is smart mobile phone or panel computer.
Technical scheme of the present invention has been improved intelligent terminal; Can directly utilize intelligent terminal to watch the audio/video flow data of set top box decodes as second screen; And new DTV remote control interactive scheme is proposed, for intelligent terminal, television set and STB provide new application mode.Existing equipment capable of using carries out during enforcement, has good application foundation, and is with low cost, is easy to implement.During practical application,, can also bring better operating experience, especially custom used the user of computer, smart mobile phone and panel computer, improve the visual experience and the attraction of television set greatly for the user through the input interactive mode of touch-screen.
