About Enhanced Channel mode
Enhanced Channel is a licensed option that combines resources from both channels into a single channel
with additional capabilities.
Enhanced Channel features include:
• External key/fill support (available when inputs are not in use for blending live video). The SDI input
format must match the video format of the primary output and must be referenced aligned.
• Two live inputs (available when inputs are not being used for external key/fill). Each live SDI input must
match the video format of the Primary SDI output and must be reference-aligned.
• Two DVE engines on a single channel.
• Two clip players for a single channel.
• Four or eight graphics layers, as licensed.
• Optional Independent Branding mode (see “Enabling and configuring independent branding” in the
Harmonic SystemManager User Guide
).
With these additional features you can:
• Brand the Secondary output with graphics different than those used for the Primary output.
• Mix video from any combination of two clip players or two live input sources.
• Use two DVE engines on a single channel, allowing squeeze-backs between player/ input
combinations.
• Use an external device to generate key or fill graphics, and overlay the graphics onto the Spectrum
X or the ChannelPort output video, along with graphics generated by the Spectrum X or the
ChannelPort.
Note that when the Spectrum X or the ChannelPort module is in Enhanced Channel mode, the
functionality of some I/O connectors will change based on your I/O Configuration selection in the
SystemManager or Spectrum Management. For instructions on enabling Enhanced Channel mode and
changing connector configurations, see the
Harmonic SystemManager User Guide
or the Spectrum
Management Help system.
