Dave would like to know if video cards with an HDMI output would allow him to calibrate his TV with his computer. Scott says that HDR calibration is in its infancy and he can get HD test pattern generators. The HD Fury Integral will add HDR meta data to do it. But for the cost, it's better to have a pro do it.
Curtis has been watching Leo on Roku and lately he's been getting HDCP errors for unauthorized access. Leo says that's just nuts. There's no reason why that's on there. But it's also problematic because everything needs to be HDCP compliant. It's clearly a spurious message because Leo's podcasts aren't copy protected. He can power it off and unplug the Roku, then plug it back in. But it's clear that something is confused.
Tom wants to know if we'll ever be able to see 4K TV over the air, because the broadcast channels have a limited amount of bandwidth. Scott says it is a challenge. In Japan, they are experimenting with technology that would embed an 8K signal inside the broadcast spectrum and they've managed to send the signal up to 17 miles. Part of the solution is through compression. Doesn't that kill the quality? Scott says they're not adding or interpolating information, they're just removing repetitive data and squeezing it. Quality and resolution will be lost that way.
Carole says whenever she downloads TWiT netcasts in HD it stalls a lot. Leo says it's probably due to the age of Carole's PC that it's having trouble keeping up with the stream. If Carole prefers HD video, then a new PC may be her best choice. Or go back to the standard definition options.
Aaron's wedding photographer lost half his wedding photos. Leo says job one of a wedding photographer is to never lose the pictures. Aaron does have HD quality video of the wedding, and is wondering if he could get stills from that. Leo says yes he can, but he shouldn't get his hopes up that the quality of the images will match the actual photos. He can take a snapshot as he watches it if the video is on his computer. Leo recommends VideoLan VLC Media Player. Quicktime player would work as well.
Scott has an antenna that has a "rotor" control which will allow him to aim the antenna as he needs. If he doesn't have rotor control, then manually rotating the antenna until he gets a clearer signal will do the trick.
Tim, a truck driver calls in to say that he has a lot of experience picking up stations and he suggests getting a VHF digital antenna, because there are a few in LA that transmit on that band.
There are multiple things to consider when buying an HD TV:
What size TV should I get?
Lynn is going to be sitting about eight feet away from the screen. Leo says he'll want a bigger TV than he might think. At about 8 feet, Leo recommends 55-60" to get a true home theater experience. There's a this distance calculator to determine what's best.
