1. Introduction
1.1 About this Manual
This user manual provides step-by-step instructions for the setup and configuration of Beam.
1.2 Overview
Beam is a WiFi-equipped H.264 encoder for applications demanding high quality, low-latency video transmission. Beam can transmit
to up to 4 decoders over WiFi or an unlimited number on a wired network using multicast. Beam supports SD/HD/3G-SDI video
inputs with embedded stereo audio and bidirectional stereo IFB communication. Beam can stream video in RTP and MPEG-TS
formats, re-stream from the decoder, and more.
