Should you buy a 4K TV? Pros and cons.
4k is named due to a 4,000 pixels accross horizontal resolution as compared to 1080p and 720p resolutions that have pixels counted along their veritcal resolutions. The new standard renders more than four times higher image definition than that of 1080p.
Dolby Atmos Explained
Dolby Atmos®, the revolutionary cinema sound technology, has come to home theaters.
With Dolby Atmos, content creators can precisely place and move sounds anywhere in your living room, including overhead, to make entertainment incredibly immersive and lifelike. This white paper is designed to explain how Dolby Atmos will work in home theaters and how you can build a Dolby Atmos enabled system or upgrade your existing system to support Dolby Atmos. This paper also explains the technological components of Dolby Atmos in home theater and the tools that content creators and broadcasters will use to create and deliver Dolby Atmos content to homes.
Understanding receiver and amplifier power
It’s no secret that it takes a lot of knowledge to truly understand the world of home audio, which is littered with confusing numbers and terms.
Wattage, current, distortion, frequencies, and impedance are just a few of the specifications anyone looking for an amplifier of home theater receiver is going to come across.
With the thousands of choices in each category, it takes a little bit of background to use these specifications to make a great choice.
In this primer from TechLore, we take a look at the power specifications of amplifiers and receivers.
What is THX? And how does it relate to Dolby Digital and DTS Digital Surround?
First, it is important to realize that THX is a quantitative measure of quality that works in conjunction with the different surround sound formats (e.g., Dolby Digital and DTS) to bring the quality of the sound presentation to the highest standards.
What’s The Reason Behind TV Sizing?
LCDs are made, several at a time on larger sheets of glass (called a mother-glass) and “cookie cut” into smaller displays. Determining how many LCDs to cut from a mother-glass is a balance of pricing and geometry. In general, larger displays sell for more per square inch than smaller displays, so there is an incentive to make as few cuts as possible. However with current quality requirements, the bigger the display, the lower the yield, as it is more likely to contain a visual defect. Further, for whatever size is chosen, the manufacturer must have orders for that size. In general, sizes are chosen so that at least 6 individual displays (cuts) come from each mother-glass but usually less than 25. An LCD maker with a yield issue may choose to do more.
Smart TV Explained
What does smart TV mean?
Like a smartphone, a smart TV offers a number of “Internet-connected services” that normal televisions can’t offer. It has the equivalent of a computer built into it, giving you a greater number of services. These televisions offer apps, media streaming, Web browsing, games and, perhaps most importantly, Internet Protocol Television (IPTV). IPTV is a specific Internet video standard, but is also used nowadays as shorthand for any video streamed via the Internet to your TV. It can take the form of short clips or continuous “live” channels.
While these features aren’t new, and have been a part of some televisions and settop boxes since 2005, the term “smart TV” has given them a name.
How 3D Works
If you were just wondering – “How does a 3D TV work?“, then this guide is perfect for you.
Ever since Hollywood began it’s recent push towards 3D with animated movies such as Beowulf, Pixar’s brilliant “Up” and of course, most recently with James Cameron’s spectacular “Avatar”, many of us have begun to fall in love with the 3D movie experience. We perceive the world around us in 3D, so why should our TV watching be restricted to 2D?
4K Projector and Video Technology
4K is an emerging standard for resolution in digital film and computer graphics. The name comes from its approximately 4,000 pixels of horizontal resolution. The fact that it describes the horizontal resolution is contrary to the standard resolutions 720p and 1080p, which represent the number of vertical pixels. 4K represents the horizontal resolution because there are numerous aspect ratios used in film — so while the horizontal resolution stays constant, the vertical resolution depends on the video source (a.k.a. letterboxing). There are several different resolutions that qualify as 4K.
Front Projector Technology
Two (And A Half) Basic Flavors
I’d love to regale you all with stories of the CRT front projectors of yesteryear. These beasts were bigger than a VW, but cost a lot more. But that’s not why I’m here. Thanks to the digital revolution, high quality front projection is now as affordable as premium rear projection TV in many cases, and less expensive than many premium flat screens.
Two and half technologies currently dominate the front (and rear) projection market: LCD, Liquid Crystal on Silicon (LCoS), and DLP (Digital Light Projection). DLP is a technology developed and owned by Texas Instruments.
LCD and LCoS are related in that they both make use of liquid crystals (therefore the “half” in the “two and a half”). But they are also different in important ways. There are also proprietary variants of LCoS, such as JVC’s D-ILA and Sony’s SXRD.
Whole House Music Systems
Of all the electronic amenities available to a new home, none are quite as enjoyable as a whole-house music system. Distributing tunes from one stereo system to speakers in far corners of a house is nothing new. Handy homeowners have been stringing wire from their stereo receivers to new speakers for years. But there is a limit to how many speakers a standard stereo amplifier can support. Plus, you may have to hoof it back to the stereo system to adjust the volume or switch from a CD player to a DSS receiver. As long as your home is unfinished, invest in a whole-house music system that’s convenient to use and safely transports songs without blowing up an amp.
Speaker Technology Primer
Speakers are available in a bewildering variety of styles, sizes, and technologies. On the technical side, the vast majority are conventional box designs using one or more drivers—most commonly a single cone woofer for the bass and midrange, a single dome tweeter for the treble, and a crossover network to divide and route the appropriate frequencies to each. The speaker cabinet, or box, which can be either a sealed or ported design, is not merely a cosmetic touch; it is a key element in the design. Without a properly designed cabinet, even the best conventional woofer would simply flap in its own breeze and produce little or no bass.
Structured Wiring FAQ
What is Structured Wiring and why should I have it in my home?
Structured Wiring is simply an advanced wiring system roughed into your new home that allows the homeowner to take advantage of new technologies and services that are available now and in the future. Examples of this are home office, high speed Internet via telephone company or cable provider. Video on demand services, Digital cable and high definition satellite and cable TV as well as in home CCTV cameras and many automation and security features. The structured wiring system sets the stage for you to share a single Internet, telephone, or digital cable TV connection with multiple computers, Televisions and peripherals all at no extra charges from the service provider. You can also choose wiring upgrades such as home theatre and whole house music to complete the integration. It is worth noting that only a few years previously, virtually no new home had these capabilities and many current homes will need to under go costly retrofits in order to take advantage of the present and future conveniences.
Surround Sound Formats Today
Despite the heavy emphasis on video over the past 15 years, the evolutions of home audio and video have actually taken nearly identical paths.
Looking back on the home A/V market in the mid 1990s the industry began a transition away from the VCR and its low-resolution video and Dolby Pro Logic audio technologies into the DVD optical disc format.
As everyone knows the DVD format offered consumers an improved picture with 480 lines of resolution and progressive deinterlacing options. It also offered a choice of audio formats that included standard PCM stereo, Pro Logic and discrete multichannel DTS and Dolby Digital.
Rooms resonate just like organ pipes. The room is an unwanted extra instrument playing along with the musicians. The design goal for a good music room is to minimize this coloration, which is strongest at bass frequencies between 20 and 200 Hz. At higher frequencies the room still has an influence, but resonances are much less of a problem since it is much easier to obtain high absorption at higher frequencies. This section deals with acoustic design within the subwoofer band of roughly 20-100 Hz.
