    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 16pieces hd input encoder modulators. This unit can easily transmits the HD signal into the RF system and pass through your current coax system.

    Hotel television is generally available either as a free to guest services, which may include local channels and satellite or cable programming, or as interactive television, which provides services such as video on demand or any other paid services including movies, music, adult content, and other services. Most of the hotels will use the cable TV system to distribute by the coax network to a set-top box in each room or to the TV with tuner inside. There are two kinds of cable TV system. One is analog system and the other is digital system. In the past 20 years, analog system is overwhelm the digital system with the low installation cost. However, with the development of techonology, now the digital system cost has been brought down almost same as the analog system. And we have to say, the picture quality of digital system stands its way. You migh check the difference below. Our company has forcus on hotel TV system for years and have help to build up tens of thousands of systems around the world both in digital and analog. To meet the need of high definition TV, we have launched the 16 in 1 digital headend encoder modulator. This digital headend is most popular used in hotels which have 150 rooms and it can distribute as many as 100 HD signal in 1080P to each room. And later we will launch the encoder modulator for home use. Check our high definition encoder modulator here.

    Trouble Shooting on Analog TV System

    Trouble Shooting Any system can be make or break the entire installation. I have been dealing with the complaint on modulators but most of the time the problem comes from the other part of system. And this is why I going to tell you in the following words. Golden Rule : Always check the connections before you blame the equipments. 1. Herringbone in TV Disconnect modulator from local channels and check modulated channel. If there is programming move the modulated channel. If the picture is snowy, use a low pass filter to block noise or data coming in from cable. 2. Horizontal Bars Rolling Through TV Picture 2.1. Check for a component of the system that is introducing DC power into the system. Disconnect that component and check TV. If the hum bars stop, use a DC blocker down stream from that component to block the power from getting to the TVs 2.2 If the rolling is only on the modulated channels, check for impedance mismatch by adjusting the video level adjustment pot. 3. Vertical Bars Rolling Through TV Picture Check for AC power getting on the line. Use a ground breaker in line. 4. Black and White Lines on one Local Channel Move modulated channel up to a new channel. If problem persists and all of the inputs of a multiple input modulator are not being used, check default channels on modulator to see if default channel is set to the same channel that the problem channel is. 5. Ghost on the Picture 5.1 Check for low quality combiner/spitter in system. Replace with high isolation combiner/splitter. 5.2 Check the type of coax used in system. Inadequate shielding in coax will cause ghosting. 6. Snowy Picture 6.1 Verify the modulator is set up for the proper TV channel band. 6.2 Verify the TV is set up on the proper TV channel band. 6.3

    SOUKA's ALL-IN-ALL-OUT headend with 16 HD input and 1 RF output, provides an intuitive interface that is both fast to learn and quick to work with. It only takes three steps and you will have a 16-HD-channel system. The 16 in 1 digital headend--SK-16D is like a small system, which is able to transmit the HD signal into any system standard(ATSC/DVB-C/DVB-T/DTMB/ISDB) connected to the network. The applications include universities, school, hospital, bar and conference rooms. You don't need to know that much on how to setting up the whole system, for we have integate the encoder and QAM modulator in that small box and set it perfectly to most of the situations. For those who want more professional settings, we also offer two kinds of control management : Mobile phone and computer software. Please find the links below: The SOUKA 16 in 1 encoder modulator headend with its compact design and competitive price has set fire to the market. However, in the coming day we will improve it from 16 HD input to 32 HD input with the same chassis.

  • The difference between ATSC and QAM
    The difference between ATSC and QAM

    ATSC is shorten as Advanced Television Standards Committee while QAM is in short for Quadrature Amplitude Modulation. QAM channels are designed to transmitted by coax, supporting MAX 38.4Mbps of data.You might see from its constellation, it's a very stable 64 or 256 points of data. ATSC channel, also known as 8-VSB, is broadcast over the air and received from an antenna to your TV. Here is the 64 QAM constellation from our HDMI encoder modulator.Comparing to QAM, ATSC carries half the data-19.2Mbps.But this standard works better than QAM in air, where it has to bounce around obastacles and deal other types of interference. So in our SK-860AH digital encoder modulator, you can have these two standards in one and you can select by  the front panel or by the android APP.  We use 8VSB for the off-air signal and 64 QAM for the cable signal.
