Scott reports that NASA is going to do the first ever, live 4K stream from Space. They will be sending it to earth at 18MB/s which Scott says is really small. The backend is being handled by Amazon's Elemental streaming and cloud based processing division, which will stream it online via H.265 HEVC and then transcoded into H.264. So to watch it online, you'll need at least 45MBps of bandwidth.
Leo got the latest BBC series Planet Earth 2 on Blu-ray and he says it's stunning. Scott says that they shot the film on the RED cameras, which have incredible dynamic range and recorded at a higher resolution at 60p before downscaling to 4K for the Blu-ray.
This week's gadget is the Vizio M Series 50" Ultra HDR TV with Dolby Vision. Somes with SmartCast, which is Google Chromecast built in. Also comes with a 6" Android tablet as it's ultimate remote and Chromecast interface. Four HDMI ports to connect Cable/Satellite boxes, Bluray/DVD players, Gaming Consoles and Computers. You can even use the virtual keyboard on the tablet to name the inputs. Be aware though this is what VIZIO calls a Tuner-Free Display. Since most households today stream or watch live TV from cable and satellite boxes which don't require a tuner, you probably won't care.
Scott Wilkinson is back and although Black Friday was yesterday, the deals are still going on. Is it OK to get a Black Friday TV? Scott says yes, if you shop carefully. A lot of them are so-called loss leaders. Those are house brands and last year's models. Check out Scott's Black Friday TV deals here.
Alan's wondering why people are buying 4K TVs when there isn't a lot of content available in 4K yet. Scott says it's because manufacturers are all making 4K TVs, and aren't even really making 1080p TVs anymore. While he's right about there not being a lot of native 4K content yet, it is growing and there is some. When you don't have 4K content, the TV will upscale it, and then the question becomes what TV has the best upscalers. So when reading reviews, look for how the reviewers evaluate the upscalers.
Glen wants to know how much resolution a DVD really has compared to a Blu-ray. Scott says DVDs are standard definition which is 720x480. Blu-ray can be 1920x1080 and above. How will it upscale? Scott says the newer his tv, the more it will upscale. If he buys a 4K TV, it will be about 10 times the resolution. The more upscaling it does, the more problems can happen. Scott says he may consider streaming from PBS. It may be in HD, rather than SD.
Leo wants to know if he should wait until February (Super Bowl time) to get his 4K TV. He's noticed there still isn't that much content out there. Scott says that's true. It's comparable to when HD first came out and most people were watching upscaled TV until the content caught up. Leo can get HD streaming and at least 720p broadcast, and of course Blu-ray discs. Now that we're moving into 4K, it's still going to take awhile for 4K content to come out, and even then TV broadcasts won't catch up for awhile, if ever.
Trevor says that if you're having trouble with your router, look for a router firmware upgrade. That often fixes connectivity problems.
Trevor is thinking of getting a curved 4K OLED TV. Leo says that there's no benefit to a curved TV. In fact, the design flaw of the curve is that a reflection will spread across the entire screen. On top of that, it's awful for people watching on the sides. It's all just marketing. He should get a flat screen.
Scott joins Leo to talk about how important it is to calibrate your HD TV. We've heard him say that time and time again, and Scott even travels up to t Petaluma to do calibrate Leo's TVs from time to time. But it's even more important with 4K UHD TVs that have high dynamic range or Ultra HD Premium. Some you have to turn on HDR Color to enable it. It's buried deep in the menus. Ideally, have a pro do it. But it's not cheap. Costs hundreds of dollars to get a pro TV calibrator to come to your home.
