about LIveShot vIdeo I/o
Summary - LiveShot will adapt to most I/O resolutions automatically and use default coding
resolutions which may be different still.
On digital video inputs and outputs, LiveShot supports 1080i50/60, 720p50/60, and all SD modes.
On
Composite In/Out
, LiveShot supports SD modes.
LiveShot video inputs are automatic; an active video input is automatically selected and the resolution
and frame rate are adapted to by the encoder. LiveShot Portable lights an indicator next to the active
video input. LiveShot Rackmount indicates the active input (and the detected resolution) on the display.
This information is also available on the web interface of each device.
Simultaneous connection of video inputs may cause issues, except in the case of the
Composite
input
on LiveShot Rackmount.
LiveShot Portable’s single A/V output is
Composite
along with
Analog
audio. Hence, all video available
here will be downscaled to SD quality, and progressive decode modes will be re-interlaced.
It’s important to note the distinction between LiveShot’s input resolution, output resolution,
and encode/decode resolution, which are independent and may be different. Input resolution is
automatically detected and adapted. Encode/decode resolution is selected in the connection profile
chosen via the user interface. On LiveShot Rackmount, the system will attempt to match the output
resolution to be the same as the video was when it was inputted to the far end encoder. On LiveShot
Portable, output is always adapted to SD modes. Under most circumstances, LiveShot will upscale,
downscale, de-interlace and re-interlace to adapt automatically. This is shown in
Figure 6
, where a
full duplex connection is presented. In the direction to the LiveShot Rackmount, the decoder output
resolution will be matched to the native encoder 1080i input signal, although all processing in between
is done at 480p. In the direction to the Portable, the output will be matched to the 480i composite
output resolution, regardless of the native input or processing resolution.
