Part 2: Broadcast-Quality Guest Interview Production From Home
This article describes the function and operation of the of a low-cost, easy to deploy, remotely operated remote broadcast system described in part 1. Rather than combine video, audio, data and power into one eye-chart, each drawing illustrates how all of the components interconnect with each other. Systems integrators provides a detailed drawings showing each physical connection, cabling, mechanical mounting, and IP configuration information.
Video Functional Diagram A pan-tilt-zoom (PTZ) high definition video camera connects to a USB port on the Mini PC Windows 10 computer mounted to the rear of the operators desktop monitor. A tripod mounted monitor faces the subject. Both monitors are connected to the HDMI ports. Video, audio and control data streams over the public internet via a secure VPN tunnel. At the far end, video and audio outputs and inputs interface with broadcaster's production studio infrastructure.
Audio Functional Diagram
The interview subject wears a lapel microphone and an IFB earpiece, just as in an appearance as a guest on live television studio set. If the guest or the producer prefer, the interviewee can wear a wireless headset for the mic and return audio..
Network Functional Diagram The 4K PTZ camera connects to a LAN switch which connects to the mini PC mounted to the rear of the local computer monitor. The camera is remotely controlled using a separate desktop app. The LAN switch connects with the existing network router at the subjects location.
AC Power Functional Diagram The PTZ camera, LED lighting panel, talent monitor, and audio mixer connect to the remotely controlled AC power strip. The remote power strip connects to an uninterruptible power supply (UPS). The mini-PC, the LAN switch and the PC monitor. Ideally the WAN router is located in the same room as the UPS. This if the optical network terminal has a battery backup. The interview can continue uninterrupted for a few minutes until power is restored, or the interview can be brought to a graceful conclusion.
Part 1 of this series explains to non-technical folks how this low-cost remotely operated system will improve quarantine guest live shots.
