The Games of the XXX Olympiad will begin in London, England, a week from today with what is sure to be a spectacular opening ceremony. And for the first time in Olympic history, a goodly portion of the entire two-week event will be available in high-definition 3D to subscribers of MVPDs (multichannel video programming distributors) reaching nearly 80 percent of US households.
Dave Duncan, Business Manager of DLP Cinema for Texas Instruments, explains the technology of Digital Light Processing, including the impossibly tiny moving mirrors on the surface of a Digital Micromirror Device (DMD) chip, 3-chip versus single-chip designs, and switching speed. Other topics include the transition from film to digital projection in commercial cinema, 2K versus 4K, 3D, high frame rates, alternative illumination sources such as lasers and LEDs, answers to chat-room questions, and more.
I recently read HT's review of the Panasonic TC-P55ST50 3D plasma TV. (Good review, by the way.) I noticed that the display was calibrated using a brightness range of 0-255. My understanding is that digital video (Blu-ray, DVD, digital TV) is encoded in YCbCr with a video brightness range of 16-235, and one should set the source component to output YCbCr and set the display to accept the brightness range of 16-235 to preserve the signal and avoid processing and interpolation. Just wanted to get your thoughts and reasons if one way is better than the other.
Live-sound pioneer and microphone maven Bob Heil returns to talk about his mic designs, new USB mic preamp/EQ, and headphones as well as his work with The Grateful Dead, The Who, Joe Walsh, and other rock legends, and his association with Paul Klipsch and organist George Wright, whose recordings helped launch the entire field of high-fidelity audio. Plus, answers to chat-room questions and more.
Is there a test disc with content that helps you dial in audio delay so the video and audio are in sync? My receiver and my Blu-ray player both have this adjustment, but it's very difficult to get it right just watching people talk. My old TV never had this issue, but my new Vizio TV seems to have an inherent delay. What do you advise as a solution?
In this episode, I show you around my new podcast studio, which is also my home recording studio, and then answer questions from the chat room, including how to position speakers, the different types of 3D for commercial cinema and home, HDMI cables, the difference between THX post processing and audio codecs from Dolby and DTS, full-range speakers and subwoofers, Dolby Atmos, Disney's WOW setup disc, and much more.
After what has seemed like an interminable wait, Vizio's 21:9 CinemaWide LED-LCD flat-panel TV is finally available to consumers at Vizio's website. With a native pixel resolution of 2560x1080, this XVT-series set is the first ultra-widescreen flat panel available in the US that displays 2.35:1 movies without black bars above and below the image.
I would like to install a 70-inch or larger high-end, networked TV in a new home-theater area. Please provide a few brand recommendations as well as LED, LCD, or plasma and why. I'm also wondering about your take on the Orb Audio speakers for that "I have never in my life experienced such completely amazing sound" for a 7.1 system. Feel free to make several other speaker manufacturer suggestions, keeping in mind a small, corner ceiling-mounted speaker system.
I have a Marantz SR6004 A/V receiver with a 5.1 speaker system, including Focal Chorus 826 V speakers for the front left and right, Chorus CC 800 V for the center channel, Chorus 806 V speakers for the surrounds, and Chorus SW 800 V subwoofer. In the receiver, I set the front left and right as Large and the others as Small. I set the subwoofer output to Off and use the receiver's Speaker C function to drive the sub's high-level inputs from the receiver's surround-back speaker outputs with the sub's internal crossover set to 60Hz. This configuration produces a very nice sound; I feel that the bass is more structured and integrated than when I use the crossover in the receiver. My question is, does the receiver lose power in this configuration?
