Embodiment
Refer to Fig. 1, the DTV receiver 100 of the utility model preferred embodiment can access to ground digital television broadcast net 300 by mobile terminal 200.DTV receiver 100 can be supported the mobile digital TV signals of various criterion and can plug to be connected in the mobile terminal 200 with general-purpose interface 210, so that mobile terminal 200 can be play the mobile digital TV signals of various criterion, thereby avoid the use of mobile terminal 200 to be subject to the restriction of region.Mobile terminal 200 can be mobile phone, panel computer etc., and general-purpose interface 210 can be the data-interfaces such as USB interface, mini USB interface.In the present embodiment, mobile terminal 200 is smart mobile phone, and general-purpose interface 210 is mini USB.
Refer to Fig. 2, DTV receiver 100 comprises Digital TV Receiving and demodulating unit 10, self-defined general-purpose interface 20, DTV pretreatment unit 30, control unit 40 and memory cell 50.In addition, DTV receiver 100 also comprises for receiving the antenna 60 of mobile digital TV signals and for DTV receiver 100 can be plugged to the Versatile Interface Unit 70 that is connected in general-purpose interface 210.
Digital TV Receiving and demodulating unit 10 carry out demodulation with the TS stream of output number format for the mobile digital TV signals with specific criteria that antenna 60 is received.In the present embodiment, Digital TV Receiving and demodulating unit 10, according to the various criterion of the mobile digital TV signals that can support, are divided into following four kinds of different types: for supporting the DVB-T type Digital TV Receiving of DVB-T standard and demodulating unit, for supporting the ATSC type Digital TV Receiving of ATSC standard and demodulating unit, for supporting the ISDB-T type Digital TV Receiving of ISDB-T standard and demodulating unit and for supporting DTMB type Digital TV Receiving and the demodulating unit of DTMB standard.Dissimilar Digital TV Receiving and demodulating unit 10 all can plug and be connected in self-defined general-purpose interface 20.So, DTV receiver 100 can by plug-in replace dissimilar Digital TV Receiving and demodulating unit 10, to support the mobile digital TV signals of various criterion.Understandably, in other embodiments, each DTV receiver 100 all has Digital TV Receiving and demodulating unit 10 fixing and support specific criteria, can receive and support the mobile digital TV signals of a certain specific criteria.
Self-defined general-purpose interface 20 is electrically connected on DTV pretreatment unit 30.Self-defined general-purpose interface 20 compatible serial parallel TS stream interface and control power supply interface etc., for being streaming to DTV pretreatment unit 30 by the TS of the number format of Digital TV Receiving and demodulating unit 10 outputs.
