1 Introduction
1.1 Product Overview
NVP are network video encoder and decoder series, which are specialized for high definition real-time
video streaming applications. It provides flexible streaming for low-bandwidth transmission applications
using H.264 video and AAC audio encoding, supporting FLV over RTMP streaming output, thus seamlessly
connecting to streaming media server. The third generation NVP series encoder –NVP-903, support 3
encoding streams output for multi-screen application. Moreover, NVP-903 integrates H.264 decoding
functions with HDMI output, to form a versatile media delivery solution over IP network.
Integrated with Caton leading R2TP technology, NVP-903 and NVP decoders can also realize high
quality live video contribution and distribution over Open Internet.
