The SKD27 digital modulator is an update version from the SOUKA's analog modulator SK-16M. It is far more felxible in install this modulator. Let's follow the below pictures to check it out.

As the high definition TV become popular, our need for high definition program is growing great. But today, we are not going to talk about the needs, we will talk about the HD connectors in the TV set. Here is the picture: 1. Tuner Input: The traditional input connector for antenna or set top box. 2. RCA Input: Set top box, demodulators and cameras 3. VGA Input: VGA connector is design to transmit the analog signal. Now it is used is on SD digital modulators. There will be certain loss if your signal is from digital source. 4. HD Input: HD connector is the best to transmit the digital signal without any loss.There are three types : HD A (Standard one), HD C (Mini one), HD D (Micro one). To distrbute the high definition signal in the hotel, SOUKA has its 16 in 1 digital headend, which is integrated of 16 pieces hd input encoder modulators. This unit can easily transmits the HD signal into the RF system and pass through your current coax system.

As our 16 in 1 encoder modulator merges into the market and becomes the hot selling product, our customers are requiring more functions, like supporting multi TV standards in one. You might think this is unless but things do happen when you need DVB-C HDMI modulator and all you have is DVB-T ones. The SOUKA digital headend has intergated 6 modulation methods and 5 digital TV standards ( ATSC, DVB-T, DVB-C, DTMB, ISDB) in just one mini size box. You might select visa the front panel or by our APP. A simple touch and the problem just gone. The features of SOUKA's 16 in 1 digital modulator headend: 1)  16 HDMI input and 1 RF output 2)  Support 1080P 60Hz input and output as 1080P 30Hz 3)  Support ATSC,DVB-T,DVB-C,DTMB and ISDB in one 4)  Support front panel contrl and Andorid phone control 5)  Output frequency range : 50 - 1000MHz

For instance, a UK MFN DVB-T profile (64-QAM, 8k mode, coding rate 2/3, guard interval 1/32) and a DVB-T2 equivalent (256QAM, 32k, coding rate 3/5, guard interval 1/128) allows for an increase in bit rate from 24.13 Mbit/s to 35.4 Mbit/s (+46.5%). Another example, for an Italian SFN DVB-T profile (64QAM, 8k, coding rate 2/3, guard interval 1/4) and a DVB-T2 equivalent (256QAM, 32k, coding rate 3/5, guard interval 1/16), achieves an increase in bit rate from 19.91 Mbit/s to 33.3 Mbit/s (+67%). Therefore, under same picture quality and same bandwidth, our T1 encoder-modulator matches the T2 requirements.
