4K HEVC Codec


The LAU-KM is SVP Aerospace´s new HEVC codec specially designed for transmission of 4 Full HD videos generated by the airborne cameras or one single 4K video. HEVC offers many advantages over AVC, such as higher compression rates which result in significant bitrate savings over tradicional AVC solutions. This additional efficiency of the HEVC encoder makes wireless transmission of 4K possible at lower bitrates.

This ruggerized codec has been designed for live applications such as transmissions from helicopter to ground, helicopter to boat and boat to boat. Latency is critical in many broadcast applications and the Lau-K codec has been designed to minimize latency without compromising quality, making this decoder suitable for all live events.

The LAU-KM compresses a single 4K UHD input or up to 4 HD of 1080p60 inputs in one stream. Each input can support 2 stereo pairs of embedded audio.

It can be configured as encoder or decoder manually by the end user.
