Integrate with EvertzAV's H.264 Encoder

EvertzAV's EV-DECS-4K-1 4K H.264 media decoder is designed to interoperate with EvertzAV's 4K H.264 encoder, the EV-ENCS-4K-1, to provide a complete end-to-end streaming-media transmission system. With the EV-DECS-4K-1 decoder and matching EV-ENCS-4K-1 encoder, you can easily build a robust system that allows for the delivery of A/V signals over a LAN or WAN.

Advanced Media Codec Technology

The EV-DECS-4K-1 decoder supports H.264 video compression technology that can decode video content with visual lossless quality for networks that have limited bandwidth. The EV-DECS-4K-1 decoder also supports AAC audio encoding technology – technology that allows you to transport high quality audio signals using minimal bandwidth.

Compatible with Diversified Networks

The EV-DECS-4K-1 decoder can receive media data via multicast or unicast allowing it to operate in many different network environments. Multicast mode saves bandwidth while unicast mode is suitable for common unmanaged switches. Even in networks protected by strict firewalls, the EV-DECS-4K-1 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, you simply need to configure the IP address of the encoder. The EV-DECS-4K-1 decoder will negotiate with the encoder and try to obtain the media stream using the most suitable approach. Additionally, the EV-DECS-4K-1 decoder provides two methods of control: web UI and Telnet API. The web UI enables control through a common web browser while Telnet API enables the devices to be controlled by a third-party system.
