Juergen Herre, chief scientist at Fraunhofer Institute for Integrated Circuits and professor at Erlangen University in Germany, discusses the development of the MP3 audio format (technically called MPEG-1 Layer 3), how lossy audio codecs work using psychoacoustics, how higher bitrates yield higher audio quality, constant versus variable bitrates, more recent audio codecs such as MPEG-2 AAC and surround MP3, 3D audio, object-oriented audio, answers to chat-room questions, and more.

Like most readers, I always dreamed of having my own dedicated space for a home theater. Unfortunately, while living in Southern California, we never had enough space. Then came a job opportunity in the beautiful state of Colorado, and our new home had a basement that was the perfect size and location for a home theater. I have a demanding job in the aerospace industry, so my available time to work on the theater was extremely limited. The process of design, prep, construction, and finishing took about two and a half years to complete. Outside of blowing insulation into the walls and ceiling and installing the carpet, I did all the work myself.

I would like to buy a TV with a 65-inch or larger screen. My budget is $3000 to $4000. Unfortunately, the room it will be in is very bright with a 15-foot floor-to-ceiling glass window behind the set facing east. I watch a few DVDs, but mostly just cable TV in HD when available; 3D is not important to me. Obviously, I am concerned about light reflection off the screen. What do you suggest?

In this week's Home Theater Geeks podcast, Boxee co-founder and CEO Avner Ronen talks about the new paradigm of streaming TV. Of course, the image and sound quality depend greatly on how much downstream bandwidth you have—for 720p, many people recommend at least 3 to 4 megabits per second (Mbps), while 1080p normally requires 6 Mbps or more. (Vudu specifies 2.25 Mbps for 720p and 4.5 Mbps for its HDX 1080p stream.)

Which leads me to ask, what is the downstream bandwidth in your home? If you don't know, there are several websites that let you measure it, both downstream and upstream; I use speedtest.net, which yielded the results shown above at my home, where Charter Cable provides my Internet access. If you know how much bandwidth you're paying for, you might want to verify it. Also, I'd love to know if your broadband Internet access is provided by DSL, cable, or another service—my impression is that cable is generally faster than DSL—so please leave a comment about that if you would be so kind.

Projection lamps: Can’t live without ’em, can’t shoot ’em. Until recently, that is.

Projection lamps are slow to turn on and off, hot, often unstable, and have a nasty habit of getting dimmer with age, while their color balance deteriorates. If you’re fussy about your video—and if you’re reading this review you should be—the 2,000-hour useful lifetime that’s usually specified (to half brightness) for projection lamps will likely be closer to 1,000 hours or less. With a replacement averaging around $400, that’s about $0.40 per hour of use, not including the bottom line on your electric bill.

I just bought a Mitsubishi WD-Y657 65-inch DLP rear-projection TV in perfect condition for $300. I've tried to find the best picture settings online, but I can't find anything for this model. Can you provide any help or suggest a good setup disc? Hopefully something easy to use, as I'm fairly new at this.

With so many TVs and BD players offering streaming services these days, I didn’t think there would be a lot of demand for standalone units; yet, they keep coming, presumably for those still watching older equipment without this feature. When evaluating these units, the most important aspects are the services and channels provided, along with the user interface. The actual streaming quality is dependent on your Internet connection (which Netgear suggests should be no less than 3-4 Mbps for 720p, though I’d say 6 Mbps is safe for 1080p).

What do you do with an underused loft space? Why, turn it into a dedicated home theater, of course! That was the challenge entrusted to Wilshire Home Entertainment of Thousands Oaks, California. The open, 400-square-foot loft required an enclosure and special acoustical materials to prevent sound leakage. The project included a new, custom staircase and the preservation of a large bay window that extends from the bottom floor to the ceiling of the second floor. It wasn’t possible to just remove it in the loft area, so it is still located behind the drop-down screen. When the theater is in use, Lutron motorized blackout shades block the light.

My Pioneer VSX-35TX A/V receiver just died. I'm looking for a new receiver in the $500 range, but I'm having a hard time finding any that have, among other things, a digital-audio output. Why is that important? I have a Pioneer TRE-D800 wireless headphone transmitter that does 5.1 audio, and it can accept either optical or coaxial inputs. Another consideration is that my Pioneer Elite PRO-510HD RPTV has no HDMI inputs, so I need a component-video output. I want a receiver that can grow from here, so 3D pass-through is a must, and 7.1 audio would be a bonus.

I'm interested in the Pioneer VSX-1122, but it doesn't seem to have all the outputs I need. The Pioneer Elite VSX-52 has exactly what I'm looking for, but it's $400 out of my range. What other brands of receivers should I be looking at, or am I just plain screwed at my current budget?
