SKD3013 3CH high-definition digital modulator is independently developed by Shenzhen Dingshengwei Electronics Co., Ltd (SOUKA Brand). The device supports three channels of high-definition signal input, encode multiplexing and 1CH RF signal output. And the frequency range of the RF output is 150MHz ~ 1000MHz. Its signal source can be satellite receiver, various set-top boxes, Blu-ray players, etc..
HD signal with output signals supports DVB-T standard TV and set-top box reception. The device can be used in public places, such as, subways, market halls, theaters, hotels,Advertising systems llike resorts. It can also be used for monitoring, training and education companies, schools, hospitals, etc. In addition, the high-definition sports channels and VIP entertainment channels are available in places, such as, bars.
Secondly, the product features and application range are as follows.
Features:
1) Support H.264 encoding;
2) Support 3 HD inputs and 1 RF output;
3) Support ISDB-T modulation standards;
4) Frequency conversion design, can be set arbitrarily within the frequency range;
5) Can work with SKD3000M chassis without complicated system settings, just adjust the frequency to the requirements, which can simplify the difficulty of the system debugging;
6) The operation interface includes: mobile phone APP, PC network management and panel buttons.
