Accompanying drawing explanation
Fig. 1 is the module diagram of Digital Television tele-control system in the embodiment of the present invention.
Embodiment
The embodiment of the present invention is by providing a kind of Digital Television tele-control system, solve the technical problem existing in prior art and cannot ensure the fail safe of digital TV broadcast signal, and then achieve the technique effect of the fail safe that can ensure digital TV broadcast signal.
In order to solve the technical problem existing in above-mentioned prior art and cannot ensure the fail safe of digital TV broadcast signal, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
The embodiment of the present invention provides a kind of Digital Television tele-control system, as shown in Figure 1, comprising: remote control center 101, wireless communication module 102, channel information administration module 103 and transmitting antenna 104; Transmitting antenna 104 connects launches encrypting module 105, remote control center 101 sends remote control notification by wireless communication module 102 to channel information administration module 103, channel information administration module 103 adjusts channel resource according to remote control notification and is sent to transmitting antenna 104, launches encrypting module 105 and is encrypted the channel resource after adjustment and launches.
In a particular embodiment, channel information administration module 103, according to remote control notification, adds channel resource, deletes, amendment, and adjustment order, merges, partition, the operation refreshing or reset.
Remote control center 101 adjusts channel resource by controlling channel information administration module 103, can provide good channel resource for user.
Data channel is connected with between channel information administration module 103 and transmitting antenna 104, this data channel is provided with detection module, this detection module is for detecting the difference between channel resource information and channel information before sent by channel information administration module 103, and this difference is carried out record, be convenient to carry out record to the Suitable content of the channel resource of adjustment in the future.Effectively safeguard channel information administration module 103.
Be sent to transmitting antenna 104 by the channel resource after channel information administration module 103 adjusts, this transmitting encrypting module is connected with launches encrypting module 105, is encrypted by launching encrypting module 105 pairs of channel resource information.Particularly, this transmitting encrypting module 105 comprises: band pass filter, frequency mixer and power amplifier, band pass filter connects channel information administration module 103 by data channel, frequency mixer connecting band bandpass filter output, power amplifier connects mixer output, thus is encrypted channel resource.Like this, even if disabled user intercuts digital TV broadcast signal, the digital TV broadcast signal intercutted also can be avoided to be sent to user by transmitting antenna 104.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
