VENTUS 2.0
1. Full CMMB U-Band Frequency table on T-PUMP
2. Correct Wrong Audio Codec info
3. When User open up MRF file, which has out of CMMB
standard at CLCH, and pops up right standard CLCH
MFS parameter for Comparing, automatically, and give
Selection to user as below picture.
We found a lot wrong parameters MFS file, who intend to make for error testing ( could be chipset designer ), or whatever
reason.
That MFS is Out of CMMB standard. So When User open up unknown MFS stream from HDD, and if the MFS stream’s is out
of CMMB standard, and will automatically pop up the above GUI form T-PUMP. And give User Comparing table current
unknown MFS with real standard MFS spec.
Customer can select one of either case, If User just intent to error testing, or possibly we could correct right standard
parameter at the Popup Menu or can do Multiplexer Frame in T-PUMP. The problem, most of user ( Receiver manufacture)
don’t know what is standard parameter of CMMB, And give them right guide. That is quite user Fridley.
CMMB mode
The recent USB CMMB receiver has trash out all FF date while on recording of on-air CMMB service for own optimizing of
size, In Demodulator side, don’t need FF data for own decoding but In modulator Side ,cannot be played if the stream has
no FF data. ( means not exact fit on standard PAD size ) “
When User open up recorded one-air signal S-MFS, and enable to play out from VENTUS, And T-PUMP will pop up the
massage as below when you try to open up “ No Padding data file “, and automatically, recovered “ standard PAD size “ for
CMMB modulation.
