Overview
YDS8924A Series Multi-channels Professional Receiver, support 24 Independent Satellite DVB S/S2/S2X tuners/ DVBT/ ATSC/ ISDB-T input to IP TS SPTS multicast or unicast outputs, has also 2 ASI inputs for external TS's sources. It is integrated with tuner demodulation, which can demodulates from 4/ 8/ 12/ 16/ 20/ 24 channel tuners, then output the IP package through different IP address and ports.
The tuners support DVB-S/S2/S2X/T/T2/C/ISDB-T/ATSC optional input, demodulate to TS and encapsulated output IP packet, IP with 3 Gigabit IP input/output (DATA1:IP output over RTMP/ HTTP/ RTSP/HLS/SRT protocol ;DATA2: IP output over UDP/RTP protocol; DATA3: 128 IP address inputs.
YDS8924A support convert various signals source, tuner, HDMI, ASI, IP to IP stream -RTMP/ HTTP/ RTSP/ HLS/ SRT for IPTV distribution, it is an ideal solution for environments where you have a large number of air channel, and widely used in IPTV system, hotel, entertainment facilities, education broadcasting systems at schools and government buildings or any kinds of source signals convert to Cable TV Broadcast System, largely cost down the source gathering of Digital TV Broadcasting System and IPTV/OTT system which based on IP construction. Being the ideal multi-channel professional receiver used for FTA (free to air) IP signal source capture from digital tuner.
