SD/HD MPEG-4 (H.264) Encoder
The standalone MEDIAEDGE®-LEB4 encoder provides real-time distribution of live video across a network to any MEDIAEDGE set-top box or software player. Working as a separate solution or in conjunction with a MEDIAEDGE Server, it encodes HD or SD sources from either SDI or HDMI inputs into an MPEG-4 (H.264) data stream, and can instantly rebroadcast the stream using an internal streaming server.

You can also use the MEDIAEDGE-LEB4 encoder to process video from a remote location, such as a video library, and then deliver the content to a MEDIAEDGE Server based at a datacenter. Content is recorded and ready for distribution across a MEDIAEDGE network.

You can combine a MEDIAEDGE-LEB4 encoder, server, set-top box and software players. Players can request live streams from the encoder—or live, scheduled, or on-demand from the server.
