Loop, PLL), bandpass filter, intermediate frequency amplifier, AGC (Automatic Gain Control, auto level control) circuit
It is formed with phase shifter, it is used to the RF signal that will receive, amplifies, filters and double conversion, converts thereof into second
Frequency signal.Demodulator intermediate-freuqncy signal is by being sent into demodulation module after filtering, amplification, A/D are converted to digital signal, most
Output TS stream eventually.
Frontend is many kinds of, and according to the difference of transmission media, Frontend has satellite set top box, terrestrial DTV
The differentiation of the various criterions such as set-top box and cable digital TV set-top box；According to hardware constitute difference, have Tuner and
Demodulator is independently encapsulated, and has that Tuner is independent and Demodulator insertion main equipment chip, also have Tuner and
Demodulator combination is completed in a chips.
Because the standard of domestic and international various market products is different (wired, satellite, ground etc.), demand difference (single channel output,
Parallel two-way or multichannel etc.), the factors such as products scheme difference form Frontend category set-top box product abundant, then plus
The influence of the pressure factor of the update and cost declining of upper product, more accelerates the frequency changed in this way.Based on the above reasons,
Set-top box drive software developer often will often transplant according to the difference of these demands, debug and test Frontend drive
Dynamic software.
Currently, the multimedia equipments product such as most DTV STBs be all based on for based on linux system or
Android system, SDK (Software Development Kit, the Software Development Kit) packet of development platform release,
The original driving of Frontend is all to be located at kernel spacing, is completed to Frontend application adaptation user's space.So moving every time
It plants exploitation and debugs new platform, or the Frontend that switching is new, require to be debugged from bottom to up, what is be related to has kernel
Configuration file, kernel, Driver Library, the multiple files in adaptation library etc., exploitation and the maintenance amount of getting up to work are big, low efficiency, along with having
Producer the driving source code of Frontend this block is not opened, it is more inconvenient that transplanting is got up.
