Entertainment-technology consultants Geoff Tully and Ron Williams, just back from the 2017 HPA (Hollywood Professional Association) Tech Retreat, talk about some of the main topics of discussion at the event. Paramount among them was high dynamic range (HDR), which Geoff addressed in a presentation advocating HDR with 1080p resolution, a concept that broadcasters embrace. Ron discussed the demo he presented with Grass Valley of a live HDR camera signal shown on an SDR monitor and two HDR monitors, illustrating how HDR actually results in greater perceived detail. We also discuss the impending ATSC 3.0 terrestrial broadcasting standard, answers to chat-room questions, and more.

Master designer Theo Kalomirakis talks about how he got involved in designing home theaters and what led him to his latest venture called Rayva. The concept is to offer pre-designed, packaged home-theater systems for rooms of various sizes at various budget levels, which cost much less than a fully custom-designed, dedicated theater room while offering very high performance. We take a look at the available floor plans and designs and talk about how all the components are integrated into a single system. Plus answers to chat-room questions and more.
