Explain: 
 
GHX-DTB02
Uses AF9005/AF9015+QT1010/MT2060(the USB host to control) composes
This product performance stable, power loss low, the picture clear smooth support clarity ground digital television program receives, automatic scan receive frequency
channel, multi- languages contact surface, sensitivity high, the volume is small, is advantageous for carries
characteristic and so on low cost, is section Gao Xingjia compares the product Two software functions introduced
1, DVB-T digital television receives
2, transcribing and supposes in advance transcribes
3, transcribing document to return to puts
4, Time-shift (time translation)
5, static picture to catch more than
6, frequency channels to look at
7, entire frequency channel automatic search ??a transmission frequency to extend 6/7/8MHz in advance all to be possible to scan ?? the frequency channel
recognition function
8, electron program guide (EPG)
9, electronic chart article
10, puts time drives, Quickly enters and quickly draws back
11, to support the multi- languages contact surface
12, brightness, the color, the contrast gradient adjustment (software edition different possibly has difference)
13, frequency channel to call back
14, most to like the program tabulating supports
15, TV pattern and the entire screen broadcasts
16, infrared remote control support (to be possible to elect)
