7 Operating the ICS-SP20
The ICS-SP20 has many advanced features to enhance the typical viewing and usability of a TV
Tuner. To select the ICS-SP20 use the Sony remote to select the Option card slot YPbPr.
A user can switch the unit on or off, control volume level, switch the current TV channel, either
directly entering channel number, or browsing through valid channels using Channel +/- keys (usually
Arrow Up/Down key on a remote controller). “Valid” channels are the channels where a valid TV signal
was discovered during recent “channel scan” operation (in stand-alone mode).
Since the ICS-SP20 allows to attach several additional video signal sources to its AV inputs, to
facilitate user selection of these inputs ICS-SP20 maps some additional “channel numbers” to its AV
inputs. So when a user selects one of these “channels”, the ICS-SP20 switches to the respective AV input.
These reserved channel numbers are based on the values selected in the service menu and could be setup
in many different ways as shown below.
26 - Composite video IN (Default is 126)
97 - S-Video IN (Default is 127)
108 - RGB+HV IN (Default is 128)
2 - YPbPr IN (Default is 129)
10 - DVI IN (Default is 130)
When a user changes to one of the channels above the appropriate input will display instead of the
normal TV channel signal.
Note that RGB and YPbPr inputs actually share the same connection (15-pin female VGA-like), so
channels 128 and 129 change only interpretation of this input. For instructions on selecting or changing a
“channel” for an assigned input, please see section 7.6 “Map A/V Input to Channel”
More advanced functionality differs in different operating modes, which is described in more detail
below and in the subsequent chapters of this document.
7.1 Remote Control Functions
The ICS-SP20 is controlled using one of directly supported IR transmitters by Sony.
When no menu is active, usual keys of IR transmitter can be utilized to change volume level and
switch channels. These control keys are:
Key: Volume+/- (”VOL”)
“VOLUME “ – volume up/down adjustment
Key: Contrast +/- (“CH”)
Change TV channel. Number and label (if was defined) of the new channel is shown at top of screen for 5
seconds.
