Chapter 7 – BRIDGE LIVE Features and
Interface Deep Dive
Encoding Incoming Uncompressed SDI to Various
Stream Types
BRIDGE LIVE provides four channels of HD or a single channel of UltraHD for SDI
input or output.
When it comes to deriving streams from incoming uncompressed SDI sources,
each SDI input can be output to multiple formats and/or destinations using H.264
(AVC), H.265 (HEVC), MPEG2, NDI and optionally JPEG 2000.
Regarding Containers and Protocols, BRIDGE LIVE supports HLS, SRT (plus
encryption), RTMP (output only), RTMPS (output only) (required for Facebook
Live), RTP, UDP, MPEG-TS and VSF-TR01.
Input SDI
All four SDI ports can be used simultaneously for 3G-SDI I/O. The SDI ports can be
used as all inputs, all outputs, or a mixture.
Alternatively, one SDI port can be used for 12G-SDI I/O, but doing so will disable
the remaining ports.
Output Stream Options
