DCH-5500P Specialized Decoder

The DCH-5500P specialized decoder complies with the GY/T 257.1-2012 “Advanced Audio-Video Coding for Broadcasting and Television – Part 1: Video” AVS+ industry standard. It is also compatible with MPEG-2 (MP@ML & MP@HL), MPEG-4 AVC/H.264, and H.265 standards. It supports AVS+/DRA decoding as well as MPEG-2, MPEG-4 AVC/H.264, and H.265 decoding. The CI descrambling feature supports multiple mainstream Conditional Access (CA) systems. Utilizing unique digital decoding technology and dual PCMCIA interfaces, it can receive various encrypted satellite/cable/terrestrial digital TV signals by replacing different PCMCIA modules.

The DCH-5500P decoder boasts a rich set of interfaces. It supports DVB-S2 input, ASI input, and TS/IP input. After performing re-multiplexing, descrambling, and demodulation processing, it can output via ASI, SDI, and TS/IP interfaces. Additionally, it enables monitoring through HDMI, CVBS interfaces, and a 1.5-inch TFT LCD screen on the front panel. It also supports the SDI Genlock function to achieve smooth switching between different SDI signal sources within the system. With dual power supply inputs, it significantly enhances product reliability. Designed for 19″ standard cabinet installation, it is the optimal choice for various digital TV front-end systems.
