1. Product Overview
1.1 Description
Sapphire-RXD3 is a Broadcast quality HEVC receiver decoding system, combining class-leading RF
technology with Ultra Low-Latency HEVC decoding, presented in a compact ½ 19’’ chassis.
The Sapphire-RXD3 cleverly combines an 8-way diversity COFDM receiver and DBS’ Sapphire Ultra-
Low Latency HEVC decoder in a single 2RU ½ 19’’ package, offering end-to-end latency of less than
40mS which makes it ideal for live action scenarios. Operators requiring legacy support for H.264
should choose the Sapphire-RXD3D which includes H.264 HD decoding.
8-way Maximum Ratio Combining diversity inputs ensure reception in the most difficult RF
environments whilst configurable LO frequencies and variable power ensures support for a variety of
external downconverters.
The Ultra-Low Latency H.265 decoder supports resolutions up to 4K in 10-bit 4:2:2 format and with full
support for HDR reinsertion, video interfaces are 12G capable. A monitoring port can be provided on
SFP which can be down-sampled to HD in the case of a 4K signal.
Sapphire-RXD3 will decode up to eight stereo audio pairs and output them embedded on SDI, one
pair of analogue audio outputs are also provided on XLR.
The Sapphire-RXD3 has a unified web-browser control interface for remote control.
Local control is achieved with a single touch screen interface offering immediate status on transmitter
performance and receiver status. The display can be set to operate in day or night modes, with
intuitive configuration entry.
The Sapphire-RXD3 enables onward streaming of video and audio and supports multiple streaming
formats including SRT. Timecode and HDR signalling are also fully supported. The Sapphire-RXD3
can support ST2110 interfaces for users requiring high rate video over IP solutions using the SFP
interface provided.
