Abstract
The utility model relates to a vehicle-mounted digital television stream transmission system. The transmission system comprises an antenna, a machine head module and a movable terminal module, which are sequentially connected with each other, wherein the machine head module comprises a television (TV) receiving unit, a signal processing unit, a display unit and a network routing unit, and the TV receiving unit is connected with the antenna, the signal processing unit is connected with the TV receiving unit, the display unit and the network routing unit respectively, and the network routing unit is connected with the movable terminal module through a network; and the antenna transmits the received digital television signal to the TV receiving unit, the TV receiving unit demodulates the received signal and then transmits the data to the signal processing unit, the signal processing unit decodes the data and then transmits the data to the display unit, the network routing unit carries out data distribution transmission, and the data is finally displayed on the movable terminal module. Compared with the prior art, the transmission system has the advantages of multiple vehicle-mounted digital television functions, improved user experience and the like.
Description
Technical field
The utility model relates to a kind of medium transmission system, especially relates to a kind of vehicle-mounted digital television flow transmission system.
Background technology
Along with progress and the consumer of technology are increasing to the product function demand, vehicle entertainment system has also obtained development at full speed, and therefore Digital Television also extensively is incorporated in the vehicle entertainment system.
Digital Television is introduced onboard system, make the interior passenger of car watch TV programme, generally use at present front dress and rear dress dual mode both at home and abroad.Comparatively speaking, rear dress mode is the most popular and the most general on the market, and the user only need to install a digital TV receiver module in car can watch digital television program; Front dress mode is also just progressing into market, and this mode is that the Digital TV Receiving function is embedded in the head, and the common and functions such as navigation, DVD integrate.But only limit at present on the High Tier Brand automobile.
Above dual mode all exists the deficiency of 4 aspects no matter adopt which kind of mode: 1. vehicle-mounted digital television function singleness, and namely the screen that can only fix in car of TV programme is play, and can not make all passengers enjoy simultaneously identical program; 2. based on the strategy of driving safety, when automobile was in driving mode, front-seat passenger forbade watching TV programme; 3. the digital television program in the car can not be presented on passenger's the portable terminal, such as mobile phone, notebook computer etc. arbitrarily; 4. present dual mode can not make the passenger have good user to experience.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of vehicle-mounted digital television flow transmission system that enriches the vehicle-mounted digital television function, improves user experience for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of vehicle-mounted digital television flow transmission system, comprise the antenna, head module and the mobile terminal module that connect successively, described head module comprises TV receiving element, signal processing unit, display unit and network routing unit, described TV receiving element is connected with antenna, described signal processing unit connects respectively TV receiving element, display unit and network routing unit, and described network routing unit is connected with mobile terminal module by network.
Described mobile terminal module comprises mobile phone, notebook computer and panel computer.
Compared with prior art, the utlity model has following advantage:
One, enriched the function of vehicle-mounted digital television: the screen that TV programme can not only be fixed in car displays the play, and can also make all passengers enjoy simultaneously identical program.
Two, Digital Television stream transmits in the distribution of in-vehicle network: fully used the net distribution technology, made the passenger watch the appreciation TV programme at the mobile terminal device of oneself by in-vehicle network, made the passenger have good user to experience.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of vehicle-mounted digital television flow transmission system, comprise the antenna 1, head module 2 and the mobile terminal module 3 that connect successively, described head module 2 comprises TV receiving element 4, signal processing unit 5, display unit 6 and network routing unit 7, described TV receiving element 4 is connected with antenna 1, described signal processing unit 5 connects respectively TV receiving element 4, display unit 6 and network routing unit 7, and described network routing unit 7 is connected with mobile terminal module 3 by network.Described mobile terminal module 3 comprises the mobile devices such as mobile phone, notebook computer and panel computer.
The operation principle of above-mentioned vehicle-mounted digital television flow transmission system is: antenna 1 receives the digital television signal that comes from eat dishes without rice or wine signal or signal generator emission, and send it to TV receiving element 4, TV receiving element 4 carries out the processing such as demodulation to the received signal, obtain the data of specific format, comprise DVB-T formatted data and CMMB formatted data, for DVB-T, refer to can be directly decoded TS data, and for CMMB, then be the data of the multiplexed frame structure that can not be directly decoded by decoder, it needs signal processing unit 5 at first to carry out demultiplexing to process and to extract required audio frequency and video and service data, then the processing of decoding, signal processing unit 5 sends decoded data to display unit 6 and network routing unit 7.The display mode of native system can have two kinds, and a kind of is directly local demonstration on the direct display unit in car, and another kind is by the mode of network data distribution, the digital television program signal is presented on passenger's the mobile terminal device.
Claims (2)
1. vehicle-mounted digital television flow transmission system, it is characterized in that, comprise the antenna, head module and the mobile terminal module that connect successively, described head module comprises TV receiving element, signal processing unit, display unit and network routing unit, described TV receiving element is connected with antenna, described signal processing unit connects respectively TV receiving element, display unit and network routing unit, and described network routing unit is connected with mobile terminal module by network.
2. a kind of vehicle-mounted digital television flow transmission according to claim 1 system is characterized in that, described mobile terminal module comprises mobile phone, notebook computer and panel computer.
