YouTube TV is now much more useful if you're a sports fan. The service is rolling out an early access multiview feature that shows up to four sports streams at once. Visit the "Top Picks For You" section and you can pick from pre-chosen multiview groups, such as NCAA March Madness games. You can jump to a full-screen view for each match, and switch the audio and captioning to the stream that captures your attention.

Importantly, the technology isn't limited to specific platforms or devices. It supports all smart TVs and living room media players that can run YouTube TV in the first place. You won't need a high-powered device like you do with some services. The trick, as the company's German Cheung explains, is to move the processing to YouTube's servers — your hardware only has to handle one feed regardless of how many streams you're watching. The tech is borrowed from YouTube's co-streaming feature.
