2.1 Introduction
Epiphans Lecture Recorder x2 is a compact, portable solution combining both
Ethernet-based audio-video broadcast streaming and recording functionalities. It
transfers up to 30 frames per second of visual and audio information with resolution
up to 1920x1080.
Input sources can be:
a DVI/VGA/HDMI display or camera source
an analog camera (S-Video or composite) source, and
an analog audio source.
This flexibility of input sources gives the Lecture Recorder x2 the capability of
synchronizing a high quality audio stream with a corresponding video stream.
Streams can be encoded with Motion JPEG, MPEG4 or H.264 video compression.
When video from the two input sources is being used for either broadcasting or
broadcasting and recording simultaneously the following format choices are
available:
1. Independent Channel Stream, streams the video from the two input
sources using two separate URLs. Recordings consist of a single multi-track
file with two video tracks and one audio track. In this mode you cannot
publish both streams through CDN or set up two multicast RTP streams.
2. Single Channel Stream, combines the input from the two video input
sources using one URL and various picture in picture layouts. Recordings
consist of one video track and one audio track.
The Lecture Recorder x2 is connected to a network with an Ethernet connection,
once connected to the network, it can be configured and operated through an easy-
to-use web interface. Recommended maximum operating temperature: 45°C. The
Lecture Recorder x2 is ideal for educational and training institutions, creating sales
and marketing videos and technical support how to demonstrations that require
the ability to stream/record/synchronize a computer display along with live video.
Each channel which is being streamed is automatically assigned a unique URL.
Viewers are simply provided with the required URL in order for them to watch the
desired broadcast stream. Additionally, the Lecture Recorder x2 allows content
producers to also record the broadcast to .AVI, .MOV, or MPEG-TS formatted files.
