Kramer’s KDS−8 is a transceiver and as such can be set to be either an encoder or decoder. As an encoder, it encodes and sends the HDMI input along with IR, RS-232 and analog audio over an IP network. As a decoder, it receives the encoded signal and decodes it for output. The KDS-8 also features an unbalanced analog audio port for embedding audio into the signal.
Kramer’s $2,000 KDS-8 4K SDVoE transceiver is designed for distributing AV signals in conference rooms, meeting rooms and classrooms. Here are more detailed specs.
