Why does my Roku give me copy protection warnings?

Episode 1246

Curtis from Virginia

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.

Will 4K ever come to broadcast?

Episode 1098

Tom from Harrisburg, PA

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.

Aaron from Los Angeles, CA

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.

Dave from Corona, CA

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.
