SKD18 series IP QAM modulator adopts compact 1U chassis, can install 3 independent digital modules. Each module supports 1 Gigabit IP input, 4 arbitrary frequency RF outputs, hot swapping. 12 RF output. DTMB, DVBC (J.83A/B/C), DVBT, and ATSC modulation mode. SKD18 series is high performance and low cost, and is very suitable for use in digital TV headend systems in various business places (such as hotels, hotels, clubs, restaurants, etc.).
Characteristics
1~3 pluggable IPQAM modules, each module has 1 Gigabyte IP input and 4 arbitrary frequency point RF outputs
IP input is available in unicast and multicast protocols, UDP, IGMP V2/V3
TS stream re-multiplexing function
RF output is available in multi-standard modulation mode, such as DVBC (J.83A/B/C), DVBT, DTMB, ATSC
