The following is an excerpt from Chapter 2: Home Theater Basics from my new book Home Theater for the Internet Age. This book isn’t for audiophiles or videophiles. If you’re an average middle class person who doesn’t know much about this topic, you outnumber the “experts” and home theater nerds by about 10,000 to 1.
I’ve always enjoyed helping people understand and embrace modern technology. In the case of home theater, this tech can bring together families in front of a big display panel for a new movie release on a shiny little disc—or, increasingly, streamed from the internet. You can enjoy family photos, MP3 songs, or home videos stored on a computer that resides nearly anywhere on your wi-fi network. All using nothing more than a decent Blu-ray player (playing discs covers only one-third the functionality of modern Blu-ray players, as you can learn here).
If nothing else, please understand that you can enjoy full surround sound, high-definition video, and all the glory of modern home theater on any budget. The most common misperception of home theater is that it’s too expensive and you can’t afford it.
But you can. Trust me.
As consumers, we’re in the middle of multiple transition periods within the home electronics and entertainment industries. These changes are in the form of rapid advances in both hardware and services. It’s no longer uncommon for one to have a 60-inch display panel hanging in their living room, to be one of the 50 million people who watch movies and TV shows on Netflix, or to be among the 76 million consumers who listen to music on Pandora each month. These don’t constitute early adopter status in today’s world of home entertainment.
Since Apple introduced its iconic iPod line of portable music players in 2001, the human race has been slowly transitioning from entertaining itself by purchasing physical media, like optical discs, to instead downloading songs from iTunes or streaming movies or TV from services like Hulu or Vudu. Today the average consumer has more home entertainment options than ever—along with a more detailed and potentially confusing array of technologies and media sources.
What Defines Home Theater?
Let’s define a few things. First, a home theater isn’t mobile. It’s not a laptop with a set of headphones (even if the laptop features a Blu-ray player). Home theater is four basic components:
- Display panel
- Audio/video receiver
- Blu-ray player
- Five+ specialized speakers
These are the elements necessary for full-on home theater and how it’s defined in this book. Anything short of these elements doesn’t cut it in terms of home “theater.” While it could be argued that a set top box for bringing audio and video content into your home theater is a necessity, some cord cutters are perfectly happy with physical discs from Redbox, the Neflix disc-by-mail service, or a local video store.
One of the most common configurations for consuming TV programming and movies is a display panel TV with two input devices: A Blu-ray player and a cable/satellite set-top box (using only the speakers on the TV). Maybe there’s a game console or DVR thrown in the mix. But this also isn’t home theater (where’s the audio/video receiver and rear surround speakers?).
In the past, the task of connecting home theater components was confusing. Different components connected with different standards and there were separate connections for audio and video. For the layperson, connecting components was a headache and typically resulted in either a frustratingly botched job, professional installation (planned or unplanned), or scouring web-based forums desperately seeking help from others. Today it’s different. Now it’s all a single standard that transports both audio and video, and does it in Blu-ray-quality high definition: HDMI. Say it with me: H-D-M-I. It’s all you need to know.
In terms of audio, the difference between a “stereo system” and a “home theater” is surround sound, which has been relatively common for well over a decade. Without a collection of surround sound speakers, home theater can’t exist. Today, a significant portion of broadcast and cable TV programming—and nearly all movies produced in the past decade—are delivered with a six-channel or greater audio mix that requires a surround speaker configuration and compatible audio/video receiver to be fully appreciated.
Surround sound isn’t just about adding more speakers in your living room. It’s about discrete channels of audio information coming from specific locations within your listening environment. In other words, the producers of a TV show or movie can purposefully make, say, the voices of the characters come from the speaker directly below your TV, where they’ll be the most realistic.
Meanwhile, background noises—such as barking dogs, slamming doors, and guns firing—can be directed to the rear speakers. The ability of content producers to utilize between five and twelve speakers in your living room, in a predictable arrangement, is why affordable home theater systems now rival the experience of going to a movie theater (and why commercial theater chains have to install football field-size screens with vibrating chairs just to get our attention).
Content services that deliver streaming audio, video, and even games to your living room home theater have proliferated like crazy during the past few years. What’s interesting is that most people have labeled this the evolution of the internet, not home theater.
It’s all convoluted today, part computer and part stereo system. We’re in the middle of the convergence of computing/internet technologies and the hardware, software, and standards on which video and audio are affordably reproduced in the home. Home theater simply does not live up to its potential without the internet and broadband connectivity. Netflix, YouTube, HBO Now, Pandora, Hulu Plus, Spotify, iTunes, and other internet-based services offer more content than you can ever consume. While your local liquor store might not sell you bourbon on Sunday, online streaming services are available on-demand, 24 hours a day, seven days a week.
