SD/HD Digital TV Decoder & Receiver
1. Product Overview
The IRD-DH3605C digital TV decoding receiver runs on Linux and complies with DVB-C standard QAM modulation. It integrates cable digital TV signal acquisition and descrambling, converting signals to IP stream output (including UDP multicast, HTTP unicast, and RTSP output). Clients can directly play the descrambled clear streams. This product supports encrypted channels with one authorized broadcasting smart card, and can descramble up to 30 SD/HD channels into clear streams and convert them to network output. It also supports user-defined video programs, making it widely used in IPTV systems for hotels, hospitals, enterprises, public institutions, etc.
2. Key Features
* Supports 5 RF CATV inputs for simultaneous multi-channel descrambling and IP stream output;
* Compatible with major CA systems; descrambles up to 30 encrypted channels into clear streams using one smart card;
(Actual channel count depends on encryption mode and total PID quantity across 5 frequency points)
* Channel descrambling authorization can be enabled or disabled based on EMM signals from the CA system;
* Built-in IPTV input; supports HTTP unicast, RTSP, and UDP multicast output;
* Supports external USB storage for loop playback of files in a directory for custom channel broadcasting;
