DE285 HD Caption Decoder/VANC Monitor

The default viewing mode for the Packet Display Module gives an overview

of which service types are present, along with their line numbers, DID/SDID

values and frequency. A more detailed view is available by clicking on

the '+' button located to the left of each VANC packet. The expanded

view displays the hex dump, ﬁeld, checksum and location/type of the

data. The hex dump begins with the sample offset in the line followed by

a colon and the hex value of each sample in the packet. The checksum

ﬁeld evaluates whether or not the checksum is valid. The Location/Type

ﬁeld displays whether it is VANC or HANC and which type it is. To return

to the default view click on the '-' button at the top of packet line.

The VANC packets are continuously updated and displayed in the chart.

If you would like the current data to remain on the screen temporarily,

click the Pause button on the top left of the Packet Display Module. To

resume seeing the live updated data, click the Resume button.
