23 FS2 Installation and Operation Manual — Technical Description
Optional Dolby ® 5.1 audio encoding card (future option) and decoding card are
available as hardware options installed by removing the top cover access slot.
Control of the FS2 can come from any of the following:
• Built-in front panel
• Plug-in remote control panel (future option)
• GPI input contact closures
• A remote computer running a web browser
Video Processors The two Video Processors are identical and perform format conversion, frame
synchronization, signal processing, and keying operations. Each video processor
has access to any video input from the Input Crosspoint Matrix.
Up, down, or cross conversion is done with very high quality scalers. De-
interlacing is performed with high quality motion-adaptive processing including
diagonal filters. The Processing Amplifier and Color Correctors support video
signal adjustment with standard Proc Amp controls and RGB-style color
correction.
The keyers in each video processor can operate in several modes:
• Add a background for HD sidebar upconversion. The background can be
Black, a user-configurable matte, video from the other video processor
(which itself can be upconverted), or a video still (future firmware release)
from the internal stillstore.
• Add a video/key graphic from the internal graphic stillstore (future
firmware release)
• Combine the two video processors in various ways, such as creating a live
“over-the-shoulder” key.
The Video Processors can also be used as a still store and output full screen stills or
test patterns.
3G Support The FS2 supports several types of 3G video (and associated embedded audio):
• 1080p59.94/1080p50 in both SMPTE level A or level B
• Muxed 3G Video: two separate 720p/1080i video signals muxed into one 3G
level B signal
In the case of “Dual Stream Video, ” the FS2 input processing can demux the two
signals and send them (each with their associated 16-channel audio) to the two
processors. For output, the FS2 can mux together the two video signals (and their
audio) from the two processors into a Dual Stream 3G video output.
Control of 3G functionality can be set to automatic (using ANC data format ID), or
with full manual control via the user interface.
