When the iPod/USB input is in use, the unit will send additional information representing
the metadata from the USB source device. This is contained in 2 separate strings and is
sent in addition to the standard feedback string.
The smart display strings represent the metadata that is also shown on the video output
of the unit. The first string contains the data present on the first line of the display. The
second string represents the remaining 9 lines of data.
Each line of data is 26 characters, and can be either ASCII characters (0x20-0x7F) or
special characters (0x80-0x8C). A reference chart for the special character data is below.
