Episode 1075

Scott Wilkinson went to see the world premiere of the Johnny Depp film "Transcendence," which was shown in Dolby Atmos, which is able to steer the sound in ways that aren't channel based and go way beyond 5.1 or even 7.1. It was shot in film and then converted to digital, which is becoming more and more rare. But it has some wonderful grain and dynamic range. Leo wonders when it became noteworthy that film is being used over digital? How did that happen? Scott says it's a philosophical choice.

Is Coin Secure Enough to Be the Credit Card of the Future?

Episode 1032

"One Card to Rule them all, One Card to Charge them. One Card to Bring them all, and in debt bind them." That's the idea of Coin, a one size fits all digital credit card that can be programmable for all cards, and can switch between them as users use it. Leo says the marketing has been fantastic with it, but he wonders how secure Coin will really be. And will merchants buy into this idea?

How can I convert the digital audio signal from my TV to analog for use with my powered speakers?

Larry from Orange, CA

Larry got a new Panasonic TV, but it has no analog audio out capability. He has powered speakers and amp that he can plug into, but he has to convert that digital audio signal to analog first. He has a preamp and converter, but it only works if he routes it through the VCR. Leo says this is the reason that people who want home theaters systems buy AV receivers. They can convert and drive multiple sources.

How can I archive shows recorded on my DVR?

Chris from Livermore, CA

Leo says that is a reasonable thing to want to do, but Hollywood doesn't want anyone to have access to that pure digital signal. DirecTV and DISH scramble and encode the signal which leaves users with only one choice - the analog hole.

Chris will have to connect the DVR to a video capture card on his computer. Then he can play back the shows and record them into the computer. This is called the "analog hole".

With digital over-the-air TV, is it normal to get a lot of digital drop outs even with a strong signal?

Episode 879

Lot from Fort Lauderdale, FL

Leo says it's not normal if he's getting a strong signal. Typically with digital, when moving farther away, the signal doesn't degrade as gracefully as analog would. Instead of showing artifacts or static, it either shows the picture or it doesn't. There's a point where the analog signal might still be there, but the digital signal isn't. If he's in range of the signal, and has a strong signal, Leo says he shouldn't get any drop-out at all.
