HDMI (High-Definition Multimedia Interface). It is the first and 
only industry-supported,  uncompressed,  all-digital au dio/video 
interface. HDMI provides an interface bet ween any audio/video 
source, such as a set-top box, DVD player,  or A/V receiver and 
an  audio  and/or  video  monitor,  such  as  a  digital  television 
(DTV), over a single cable.

from ATSC broadcast programming, this input takes  advantage 
of the High Definition content.

TV Coaxial RF.  This is the  connection for  standard NTSC  TV 
using antenna or cable.

(analog)   Blue 
RGB PC (VGA). This  video input has  separate red, green  and 
blue  color  components.    The  signal  carries  horizontal  and 
vertical sync  information  on  the  green  signal.    This  is  most 
commonly used for PC input.

Yellow 
Component. The video  signal is  separated into  three signals, 
one containing  the  black-and-white information  and  the  other 
two containing the color information. This enhancement over S-
Video  takes  advantage  of  the  superior  picture  provided  by 
progressive scan DVD players and HDTV formats. 
Good 
(analog) 
Red 
S-Video. The  video signal  is  separated into  two  signals, one 
containing  the  black-and-white  information  and  the  other 
containing the  color  information.  Separating  the  color  in  this 
way avoids ‘cross color’ effects where closely spaced black and 
white lines are  erroneously displayed in  color.   It also enables 
text to be displayed more sharply. 
Good 
(analog)   Red 
Composite. The complete  video signal  is carried  through this 
single pin  connector.  This is  the  most  commonly used  video 
connection.

USB (Universal Serial Bus). USB is an interface port designed 
to connect  storage devices  holding data  (FAT32  format: MP3 
for music and JPEG for image) files without a need to power off 
the host (TV) unit.
