selected URL in a new browser tab.
Smooth Streaming target chunk
For Smooth Streaming, this specifies which chunk, counted from
the bottom of the list, the VB220 should download when doing
active testing on a live channel. For other formats, this option is
ignored.

entering the IP address or hostname of the VCAS server’s en-
coder interface will allow descrambling of the encrypted chunks.
See OTT descrambling with Verimatrix for more info.

presence but not download the entire file. This also disables
thumbnail generation.

for the selected channels in the Active testing and Thumbnails
