specific Embodiment approach 1

[0021] As shown in Figure 2, the DVB-H-based external TV signal portable receiving device includes an antenna, a video signal tuning unit, a video signal demodulation unit, and an output unit that are sequentially connected.

[0022] Among them, the video signal tuning unit tunes the DVB-H digital TV signal received by the antenna and then inputs it into the video signal demodulation unit; the video signal demodulation unit demodulates and compresses the received tuning signal processed by the video signal tuning unit into Video stream in MPEG-2 format; the output unit uses a USB interface. When in use, the USB interface is connected to a mobile phone with a USB port, and the video stream in MPEG-2 format is input to the mobile phone through the USB interface, and the mobile phone can play and receive it through the playback software Video signal.

[0023] The above-mentioned video signal tuning unit adopts the MT2260 digital chip produced by Microtune. The chip has a large market...

specific Embodiment approach 2

[0031] As shown in Figure 3, the difference from the first embodiment is that the device also includes a battery connected to the video signal tuning unit and the video signal demodulation unit, and a power management unit for charging and managing the battery. The interface takes power to charge the battery.

Abstract

The invention discloses a portable receiver of external TV signals based on DVB-H, comprising an antenna, a video signal tuned unit, a video signal demodulation unit and an output unit which are connected in order; the video signal tuned unit tunes DVB-H digital TV signals received by the antenna and transmits the signals to the video signal demodulation unit; the video signal demodulation unit demodulates received tuned signals processed by the video signal tuned unit and compacts into video streams; the output unit is used for outputting the video streams to an external portable terminal. The invention does not need any structure changes of prior portable terminals such as mobile phones, only needs a play software to be installed, then is connected with the output unit of the external TV signal portable terminal based on DVB-H, mobile phone digital TV programs provided by traders can be received.

Description

Technical field [0001] The present invention relates to an electronic device, in particular to an external TV signal portable receiving device based on Digital Video Broadcasting Handheld (DVB-H). Background technique [0002] With the development of communication technology, portable terminals such as mobile phones, personal digital assistants (PDAs), and handheld game consoles are becoming more and more popular in daily life. At the same time, as the digital video broadcasting environment gradually takes shape, the concept of mobile TV is also Increasingly mature, such as mobile TV and so on. At present, domestic mobile operators, TV stations, content providers / service providers (CP / SP), terminal manufacturers and some system integrators have begun to pay attention to the new business of mobile TV, and have carried out trial operation within a certain range , Including the special production of programs, the adjustment of data traffic fees, and appropriate promotion. Although t...
