Glossary
Aspect Ratio—The aspect ratio of a television picture is the
relationship of the width to the height. The standard Analog aspect
ratio is 4:3. The 16:9 aspect ratio appears wider and shorter, more
closely resembling a movie theater screen image.
ATSC—Advanced Television Standards Committee.
Brief Banner—Station ID channel number, and time display that
appears when changing channels.
Brief Channel Number Display—The small display that appears
when entering channel numbers.
Category Tab Area—Tabs are located at the top of each main
on-screen display: Menu, CHannel Map, or V-Guide.
Channel Search—This process establishes the basic database. The
search process looks for available channels in both tuning systems
(DTV and NTSC). If a signal is present, the channel is added to the
database. The database will be entirely reset anytime a full Channel
Search is completed. If the search is started from the Menu, then the
display returns to the Menu after the search is finished.
CHannel Scan Memory—This is a list of active channels that is
created during the Channel Search process and stored in memory.
Viewers can scan through this list using the Up/Down Scan keys.
This area is also used to delete unwanted channels. (Channels
viewers want to skip over when scanning.) However, to undelete a
channel, another Channel Search will need to be completed. For
DTV, the CHannel Scan Memory will include only major channel
numbers.
CHannel Map—This displays pages of ALL available channels in
the database and their status. Channels that have been removed from
the CHannel Scan Memory will appear as blue numbers. Any
channel can be selected from the CHannel Map, even the “blue”
channels.
For DTV, the CHannel Map will show only major channel numbers.
Channel Number Entry Area—This area is used to actually select
a channel number when adjusting or setting the Scan Memory and
Initial Channel features.
Channel NightScan—NightScan searches for new DTV channels
and adds them to the channel database. This search will be
performed at random intervals (during an inactive time).
Cursor Keys—The CURSOR keys are the four arrow keys on the
remote control and on the SDB front panel. When accessing any
page, menu option, or condition, the front panel keys and the remote
control keys operate identically.
DTV—Digital Television. Picture is transmitted in a digital format
that is sharp and crystal clear.
DTV Indicator—Indicates a digital (ATSC) channel is being
received by the SDB.
Direct Channel Selection—This allows the viewer direct access to
DTV and NTSC channels. Use the 0-9 number keys to directly enter
a new channel number. Use the (–) SUB CH key when necessary.
HDTV—High Definition Television. Picture is transmitted in a
highly defined format.
Initial Channel—This feature allows the customer to select a
specific channel for the SDB to tune each time the unit is switched
on. If not set, the last watched channel will be selected.
NTSC—National Television Standards Committee.
OSD—On Screen Display.
PCM—Pulse Code Modulation is a binary digital signal format
used for digitizing analog data. The SDB outputs PCM audio signal
from digital audio output. This is the default digital audio output
signal.
SDB—Sanyo Digital Box.
S/P DIF—S/P DIF is a digital audio format which can transmit a
Dolby Digital bitstream. By connecting this output to an AV
receiver that includes a Dolby Digital decoder, you can reproduce
up to 5.1 channel surround sound.
Tuner Indicator—A single character “D” or “C” will appear
directly to the left of the channel number. Channels selected with
the digital (DTV) tuner will be identified with a “D.” Channels
selected with the analog (NTSC) tuner will be identified with a
“C” if cable or will be blank if Off-Air (VHF/UHF).
Tuner Key—This key is used to switch between only two choices
(the ATSC tuner and NTSC tuner).
480P Indicator—Indicates that the progressive video scan option is
selected.
4:3 Indicator—Indicates the 4:3 option is selected for the aspect
ratio.
