    SD/HD H.264 real-time IP video encoder

    The Grass Valley™ MEDIAEDGE® LEB Express encoder offers real-time hardware-based H.264 encoding and distribution of live video across an IP network. It works as standalone unit and will accept HDMI and composite signals for its video source, with frame synchronization capability. Working as a separate solution or in conjunction with a MEDIAEDGE system, it can instantly rebroadcast the stream using an internal streaming server.

    You can also use the LEB Express encoder to process video from a remote location, such as a video library, and then deliver the content to a compatible video decoder such as the MEDIAEDGE STB4, SWT4, SWT4 for Mac, or record and re-distribute it with MEDIAEDGE SVS4.

    You can also use our SDK for your system/application development. The SDK includes sample software, including reference source code.
