3. TECHNICAL BRIEF
3.5.9 DVB-H/T Block
DVB-H/T system block diagram is shown in the figure below. You can see the flow of DVB-H/T signal by
the below figure.
First of all, you can see the antenna & the GSM rejection filter. The GSM rejection filter is used to protect
the DVB-H/T signal from the GSM interference which is near the DVB-H/T signal band. First, DVB-H/T
signal passes through the antenna and the GSM rejection filter. And the tuner in DVB-H/T IC receives
signal from the filter and passes the signal over to the demodulator which demodulates the receiving signal
and passes it to the DSP. DSP receives the signal from the demodulator and decodes the signal, so that it
can play sound with the speaker and display the video of DVB-H/T signal through LCD. The DVB-H/T
signal path is in the next page.
