VIDEO CODECS

4K HEVC Encoder

LAU-K-SFP

The Lau-K-SFP is the new HEVC codec developed by SVP Broadcast Microwave. Offering exceptional compression ratios on video resolution up to 4K UHD for contribution.

HEVC offers many advantages over AVC like HEVC compression which results in significant bitrate savings over tradicional AVC solutions.

The additional efficiency of HEVC encoder makes wireless transmission of 4K possible. This decoder supports low latency making it ideal for live applications such as wireless cameras, ENG, SNG and Aircraft Data Links.

Latency is critical in many broadcast applications and Lau-K codec has been designed to minimize latency without compromising quality, making this codec suitable for all live events.

The Lau-K compresses a single 4K UHD input or up to 4 HD of 1080p60 inputs in one unit.

The SFP interface makes it easy to switch between different input sources; SDI, HDMI and optical fiver.
