What is a Smart TV?

In a nutshell, a smart TV incorporates an operating system/platform that allows you to access, manage, and view online and network-based media content without the need to connect to an additional box.

How Smart TVs Work

Smart TVs access online content by connecting to the same broadband router via Ethernet or Wi-Fi connection that you use to connect your PC to the internet. Ethernet provides the most stable connection, but if your TV is located in a different room, or a long distance from your router even if it is in the same room, Wi-Fi may be more convenient.

Once connected and turned on, you enter any needed login information required by your ISP (Internet Service Provider).

After signing in, the smart TV will display an on-screen menu that includes a list of available internet channels, which are provided in the form of apps (similar to the apps on a smartphone). Some apps are pre-loaded, while others can be downloaded and added to the TV's "app library."

When you click on the icon for a specific channel/app, you are taken to their content offerings, which you can select and view.

Depending on the brand and model, there may be differences on how you navigate through the smart TV menu and manage your apps.

The Benefit of Smart TVs

The main benefit of a smart TV is access to a large number of "channels" that offer TV programs, movies, music, without having to connect a TV antenna or subscribe to a cable/satellite service. Also, some smart TVs may provide web browsing, gaming, as well as access to compatible media content stored on your PC.

Although smart TVs also have the ability to receive TV programming via antenna or cable/satellite, Vizio has actually taken the bold step of eliminating built-in tuners and antenna/cable connections on most of its sets in favor of its built-in streaming platform as an all-encompassing replacement.

Additional Smart TV Features

In addition to internet streaming, some smart TVs provide more capabilities, such as Miracast and Screen Sharing which allows users to view content from compatible smartphones and tablets on a TV screen. Other labels for this feature include SmartShare (LG) and SmartView (Samsung).

Also, some smart TVs may be able to do the reverse - send content from the TV to a compatible smartphone. After sending, the user can continue to view that content on their smartphone away from the TV.

Extra Costs and Limitations

The hype surrounding smart TVs is compelling, but there are some cost and limitation factors to consider.

  • Although smart TV platforms provide access to a lot of free channels and services, most do require either a monthly subscription or pay-per-view fee. When you start adding up those costs, you could end up spending as much, or more, than a monthly cable/satellite bill. On the other hand, you will only be paying for the channels and content you actually want.
  • The brand/model smart TV determines what services and features you have access to. Although all smart TVs access a lot of the same core services (Netflix, Vudu, Hulu, Pandora), there may be a lot of additional and niche channels that you may desire that may not be accessible on some smart TV platforms. Also, for those that use iTunes to access streaming audio and video content, there is no TV that has this capability - so even if you have a smart TV, you still need to purchase an Apple TV box.

Smart TVs May Be Able to Spy On You!

Using a smart TV may result in privacy issues. Smart TVs and/or the content app providers, usually track your viewing habits in order to provide you with viewing suggestions. For example, every time I log into Netflix, the menu shows me what I have watched recently, as well as updated suggestions for related movies or programs that I might like based on my "watched recently" list.

You might think that this type of tracking is a good thing because it cuts down search time for movies or programs to watch, but a smart TV may be doing more than just track your viewing habits.

If your smart TV has a webcam or voice control, there is a possibility that someone can hack in and see/hear you. Also, any credit card purchases you make using your TV may be track-able by third parties. If your voice control or webcam is on—don't say or do anything that you wouldn't do or say in public—and be cautious with your online credit card purchases.

Smart TV Alternatives

If you recently purchased, or currently have, a TV without smart features or an older smart TV with limited options, if that TV is still working well, and satisfies your picture quality needs, you don't necessarily have to buy a new smart TV. There are devices that allow you add smart features to your current TV viewing experience, at minimal cost.

Media Streamers

  • One way to add smart features is by using a media streamer. A media streamer can be a small box that plugs into your TV's HDMI port and connects to your internet router via Ethernet/WiFi. If you have an older TV that does not have an HDMI input, your options are more limited, but Roku's Express+ media streamer provides analog video audio connections for those cases.
  • Another type of media streamer is a stick that is slightly larger than a USB flash drive, but, instead, plugs into a TV that has an available HDMI input. The stick-type media streamer only provides WiFi, so make sure you have a wireless internet router. The stick also needs to connect to a USB or AC power source.

Blu-ray Disc players

  • Another practical way to add smart features to your TV viewing experience is with a Blu-ray Disc player. In addition to playing physical media (Blu-ray discs, DVDs, CDs) almost all Blu-ray Disc players provide access to a number of internet streaming channels (depending on brand and model).
  • However, the internet channel selection is usually not as extensive as with a media streaming box or stick, but it is certainly convenient as you don't have to connect both a media streamer and a Blu-ray Disc player to your TV - which cuts down on cable clutter. If you are a fan of DVDs, Blu-ray Discs, and CDs, but want to add streaming as an additional content source, a Blu-ray Disc player may be the solution for you.


  • Companies such as Channel Master, and TIVO market over-the-air DVRs that combine reception of over-the-air TV signals, video recording, and internet streaming in one box.
  • Just as with Blu-ray Disc players, the internet channel selection may be limited, and recording features only work with the over-the-air received TV programs, but it does provide another option that "cord cutters" can take advantage of. However, the DVR option is more expensive than the media streamer and Blu-ray Disc player options.

Stereo or Home Theater Receivers (Audio Only)

  • Although smart TVs and media streamers include some online music channels, if you are a big music fan, you may opt to purchase a network-enabled stereo or home theater receiver. This option not only provides access to several streaming music services but plays that music back through a stereo or home theater speaker setup that provides a much higher quality listening experience than built-in TV speakers or even a TV combined with a soundbar.

The Bottom Line

When shopping for a TV, just about all brands/models offer some level of smart functionality that expands your viewing options.

However, be aware of variations in content access, additional subscription/pay-per-view costs, possible privacy issues, and the need to balance the attractiveness of a specific smart TV with other important factors, such as picture quality, sound quality, and physical connectivity.

If you want to add TV, movie, and/or music streaming and other smart features to your home entertainment experience, and don't know if you need a smart TV, here are some guidelines:

  • If you are buying a new TV and don't have other devices that provide access to internet streaming content, then getting smart TV is a good choice.
  • If you already have a smart TV, but it doesn't provide access to the number or type of streaming channels you would like, instead of buying a new smart TV, consider adding an external media streamer, streaming stick, or internet-enabled Blu-ray disc player that may offer what you need.
  • If you already own a TV that doesn't have smart features, but you are satisfied with its picture quality and other features, you don't necessarily need to buy a smart TV. Just as in the previous suggestion, you can opt to add a media streamer, streaming stick, or internet-enabled Blu-ray Disc player to your current TV.
  • If you are concerned about privacy issues, although an external media streaming device wouldn't prevent purchase or viewing habit tracking—it would prevent any direct audio/video spying—so it would be a better streaming choice than a smart TV.
  • If you are interested in audio-only streaming, getting a network-enabled stereo or home theater receiver would be able to provide more desirable sound quality for music listening than a smart TV.

    A smart TV is just one way to add internet streaming and related features to your TV viewing experience, and based on the guidelines listed above, it may, or may not, be the best choice.
