Diversity Receiver

UDR-104 Fiber

The  new  UDR-104 Fiber receiver performs DVB-T2, DVB-T and ISDB-T demodulations. DVB-T2 modulation outperforms DVB-T modulation and offers a much higher data rate, and therefore, a higher quality signal or much more robust signal than DVB-T, enabling longer and more complex links.

This receiver has two dual channels of optical fiber in DVB-T2, DVB-T and ISDB-T demodulations, using spatial diversity based on MRC technique (Maximum Ratio Combining) . It features HEVC, H.264 and Mpeg-2 encoding for 12G, high definition (HD) and standard definition (SD) signals with ultra-low latency. HEVC allows the same video quality, reducing file sizes by up to 50% compared to its predecessor, the H.264. Among the improvements of this new receiver is the ability to receive one 4K UHD signal with HDR at 10-bit 4:2:2 quality or 4 simultaneous 1080p50/59HD signals. This receiver has an integrated camera control system compatible with Sony, Grass Valley and Panasonic.

This new generation receivers have several outputs: 12G, 3G, HD/SD-SDI, Transport Stream over IP and SFP optical output. User  data  or  GPS  data  can  be  received  over  the  data  channel. ASI  input  and Transport  Stream over IP input enable its use as a standalone decoder. Besides, the ASI output and the Transport Stream over IP output enable the user to handle the receiver as a demodulator.

Their easy control, operation and monitoring make our receivers very manageable. All interfaces are user-friendly: the front panel and display, serial commands and web-browser.
