The new set for “CBS This Morning” looks to the network’s past for inspiration. Some of the highlights include the unique glass desk for the three co-hosts and the 186in “Magic Wall” display screen.

Also in this issue, Broadcast Engineering looks at the criteria for building an active archive, the FCC’s online caption requirements, circular polarization for mobile and compression for digital cinema cameras.
