The Greylock H.264 Encoder/Decoder from Videon is a Full HD video-over-IP encoder/decoder designed for AV installations including houses of worship, live events, sports, and education. It features an HDMI input and output as well as a 3G/HD/SD-SDI (BNC) input for connecting to your source devices. Audio embedded in HDMI and 3G/HD/SD-SDI sources is processed, and a 3.5mm analog audio input jack enables a separate audio source to be embedded with the video stream. Use the Greylock for unicasting or multicasting your content over platforms such as Wowza, UStream, YouTube Live, EvoStream, and DaCast.

The compact Greylock uses its Intel Atom CE5300 Processor for H.264 compression, offering Baseline, Main, and High profiles. Audio features include MPEG-4 AAC-LC encoding, 48 kHz sampling, and MPEG-1 Layer II and MPEG-2/MPEG-4 AAC audio decoding. The Greylock can encode video at rates up to 1080p60, with video bit rates going as high as 20 Mbps, or as low as 250 kbps for delivery over bandwidth-constrained networks. Link this encoder/decoder to your network via its RJ45 10/100/1000 Ethernet port.

Network and control features of the Greylock include a web-based UI (user interface), integration with third-party controllers and applications, HTTP command and control, and auto-detection of other Videon units on your subnet.
