10-5. COMMANDS DESCRIPTION
Values sent or received are in decimal.
Depending on the command letter, the value can be used as a linear control (ex : 255W to set the horizontal size to the
maximum) or as a set of bits (ex : P command with multiple controls).
In this case, the value must be converted in binary base to understand every bit action.
EXAMPLE: Host receives message CSTA25 (P command)
Decimal value 25 = Binary value 11001
25 = (32 x 0) + (16 x 1) + (8 x 1) + (4 x 0) + (2 x 0) + (1 x 1)
bit 0 = 1 means sync. detected.
bit 1 = 0 means H & V sync. detected.
bit 2 = 0 means non interlaced format detected.
bit 3 = 1 means computer selected = "referenced" computer.
bit 4 = 1 means the "Ref computer" format is in the range of compatibility.
bit 5 = 0 means the FADE and TITLE effects are not active.
