CHAPTER 2: OVERVIEW
2.1 INTRODUCTION
VS-2001-DEC works with a live streaming media encoder (VS-2001-ENC) that interfaces with HDMI signals for delivering media
over IP networks. With this decoder and matching encoder, the user can build a system to deliver an A/V signal over a LAN or WAN.
Advanced media codec technology
The decoder uses H.264 video compressing technology to decode video content with visual lossless quality at the link that
provides limited bandwidth. The decoder also supports AAC audio encoding technology so the audio signal can be delivered with
low bandwidth but high quality.
Compatible with diversified networks
The decoder can receive media data by multiple approaches to work in many different network environments. Multicast mode
saves bandwidth and unicast mode is suitable for common unmanaged switches. Even in a network protected by a firewall, the
decoder can activate RTP over RTSP mode to receive media data without the need for a new UDP port.
Optimized controlling methods
To achieve pairing, the user needs to configure the IP address of the encoder. The decoder will negotiate with the encoder and try
to obtain the media stream by the most suitable approach. You can control the decoder in two ways: via web UI and Telnet API.
The web UI enables the user to control it through a common web browser. The Telnet API enables the devices to be controlled by a
third-party system.
