Depending on facility environment cost, the utility model provides a kind of TV programme are played on intelligent terminal equipment based on WIFI.
The utility model is for the technical scheme that above-mentioned solution technical problem is used：One kind will be broadcasted based on WIFI hot spot
The equipment that TV programme are played on intelligent terminal, including RF antennas, tuner, demodulator, digital television signal controller,
WIFI signal transceiver, CPU, microcontroller and WIFI antennas, wherein：
RF antennas, receive the terrestrial broadcast television signal of 42M to 1002M, and are of coupled connections with tuner；
Tuner, locks a frequency for frequency, and the information of the frequency is extracted, and uses I2C interfaces and demodulator
Communication；
Demodulator, is demodulated to data signal, and demodulator is controlled using I2C interfaces, will demodulate the letter for coming
Breath is transferred to digital television signal controller in the form of TS streams, while being communicated with CPU using I2C interfaces；
Digital television signal controller, the TS circulations that will come from demodulator transmission change the data message of USB interface into, and lead to
USB interface is crossed to be communicated with CPU；
WIFI signal transceiver, is converted into the 2.4G radiofrequency signals of reception digital information and is communicated with CPU, equally will
The WIFI radiofrequency signals that the digital information that CPU sends is converted into 2.4G send WIFI antennas to；
Microcontroller, is controlled to power supply, button with switching on and shutting down logic and corresponding lighting effects；
CPU, is responsible for the control of system, and data are processed and transmitted；
WIFI antennas, tranmitting frequency is the WIFI radiofrequency signals of 2.4Ghz to intelligent terminal.
Operation principle of the present utility model is：The equipment can set up WIFI hot spot by WIFI antennas after powering, intelligence
Terminal device connects the equipment by WIFI, and search is completed in the supporting application program operation interface of intelligent terminal
The operation of program, now equipment the terrestrial broadcast television signal of corresponding frequency can be scanned for demodulation, and TS is flowed
Program list information is transmitted and is presented in the Application Program Interface of intelligent terminal by WIFI.User arranges in TV programme
Table selects corresponding program, now equipment end during according to the selection of user, TS is flowed corresponding programme information intelligence is transferred to by WIFI
Energy terminal device simultaneously calls media player to decode and play information.Described herein to be, intelligent terminal is supporting
Application program can be existing program on the market, such as DTV prefabricated in DTV STB is played and applies journey
Sequence.
TV programme are played on intelligent terminal equipment based on WIFI of the present utility model is higher with present popularity rate
Intelligent terminal（Such as mobile phone）As the instrument of broadcasting, more convenient, portable ground digital electricity can be not only realized
Watched depending on signal, while greatly reducing the cost built and watch digital television devices environment.
Brief description of the drawings
Fig. 1 is the fundamental diagram that the utility model is based on the equipment that WIFI plays TV programme on intelligent terminal.
Fig. 2 is that the utility model is based on the circuitry principle square frame that WIFI plays TV programme on intelligent terminal
Figure.
