1. Model D9040 Encoder
Description
To help optimize bandwidth utilization in digital
transmission systems, the Model D9040 Encoder is
designed to deliver high-quality MPEG-2 video in a small
amount of bandwidth, allowing efficient utilization of
bandwidth constrained mediums such as satellite.
The PowerVu® Network Centre (PNC) can provide
control of multiple D9040 encoders, providing conditional
access and managing the services through the primary distribution chain for programmers and broadcasters.
The D9040 Encoder incorporates PreSightPlus, which is an adaptive and motion-compensated noise reduction
technique that provides picture quality in a noisy environment, and is suitable in both contribution and distribution
applications.
The D9040 Encoder offers built-in support for SCTE-35 digital program insertion (DPI) via contact closure. This
feature can be used to drive digital splicing equipment in headends for ad insertion or local programming. The
D9040 also supports cue trigger transmission based on contact closures, which can be used for analog
applications in conjunction with PowerVu decoders.
