3. TECHNICAL BRIEF
3.5.9 DVB-H/T (U104 : DIB9080H)
■ DVB-H/T block diagram
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.
