Posted date : 2020.04.15

Introduction

Do you ever wonder what it’d be like to be able to participate in an event from a location far away and yet experience a sense of reality as if you were actually at that place in that moment? Using the THETA live streaming function, users can share remote spaces with others. Wouldn’t it be wonderful if you could remotely view your child’s kindergarten recital, school entrance ceremony or graduation ceremony using your smartphone or VR goggles even when you’re unable to be there physically? With this function, you can even spin the 360-degree video and get a close-up of just your child or whatever you want to focus on.

Alternatively, using THETA’s VR Live, you can watch music concerts or pop idol concerts remotely and not just enjoy the overall performance, but even get close-ups of your favorite idol group members.

Equipment and system configuration

There are various methods to view and stream VR Live using THETA. This article introduces a method using YouTube to stream and view from THETA at up to a resolution of 4K and speed of 30 frames per second. This explanation uses the THETA Z1 and a Mac PC. Both video and sound can be streamed and viewed.
With the system configuration shown in the figure below, VR Live can be streamed stably for over 5 hours.

Operation has been tested with a Mac Book equipped with Mac OS Ver. 10.14.
