In 2008, Pioneer introduced a 50-inch plasma TV and became one of the first companies to get rid of the tuner. The Pioneer Kuro KRP 500A monitor has two wires: one is the power cord and the other is the data cable for the separate media receiver. This is a very good feature for TVs that are about to hang on the wall. You can easily connect DVD players, video game systems, speakers, and other devices to this separate box. In the same year, Philips introduced a 42-inch Essence LCD TV. This separate media integrator uses a line to provide power and data for the screen. It was also in this year that Sony introduced the first OLED TV; its 11-inch XEL-1 put all electronic devices in the stand, emphasizing the slimness of this display technology.
The trend of separating electronic devices continues. For example, both Samsung and LG are selling ultra-thin LCD TVs and OLED TVs that separate electronic devices. They use Samsung's "One Connect Box" model to place electronic devices in separate boxes, or like Like the Signature G6 OLED 4K TV launched at the 2016 International Consumer Electronics Show (CES), LG deployed electronic components in a stand.
These TVs may look new and stylish, but they still use dedicated tuners. Even if you don't use a tuner and use a device that can send video streams to deliver TV programs, they are still TVs. Devices that can send video streams include smartphones, tablets, and personal computers, as well as some small peripherals (such as AppleTV and Roku models) dedicated to navigation and streaming Internet video, and dongles (such as Google Chromecast and Amazon Fire. TV TV stick).
These peripheral gadgets can also be compatible with screens without a tuner (such as a computer monitor), as long as the monitor has a high-definition multimedia interface (HDMI) and speakers (in fact, many displays have HDMI, but no audio functions, thus limiting They function as TV alternatives.)
Even with these available products, if you want to transfer the entire TV functionality to your computer monitor, you still face a major obstacle. Without the addition of a suitable tuner, it would be impossible to receive signals from cable television, satellite antennas or ordinary antennas, and it would be impossible to receive many pure cable television networks, such as the American Turner Classic Movie Channel and British Virgin Media. However, this limitation is gradually weakening because the on-demand service now allows video content to flow across the Internet, including Netflix, Comcast Xfinity, ESPN Player, HBO Go, and Hulu. These services can provide almost all current television series, a large number of movies and television programs, but does not include news and regular webcasts of most national and local television stations.
This does not mean that news and regular broadcasts cannot be transmitted over the Internet. If broadcasters are willing to provide such content online, most homes do not need any type of TV tuner. This day is coming - maybe faster than you think.
Even people who haven’t fully accepted the video on the Internet do not need a TV tuner anymore. Today, the use of the tuner is limited to attaching it to an antenna (usually on the roof) to receive over-the-air broadcast signals. Most people watching "traditional" TV channels get their signals through satellite or cable TV. They use a method of connecting to an external box instead of using a TV tuner. The US Consumer Electronics Association estimates that only about 7% of households in the United States, that is, about 8 million households, receive air television signals. In other parts of the world, many more people are watching through airwaves: In Asia, 20% of television-owning households rely on rooftop antennas to receive television signals; in Europe, this proportion is 40%.
However, even outside the United States, people have become accustomed to watching videos using devices without tuners (such as mobile phones, tablets, and computer monitors). Ironically, the effort to integrate the tuner into various devices over the years has failed - people feel that they can't watch TV at their desk or while they walk.
With the pressure of thinner displays, more and more manufacturers may quietly discard the cigarette-box-sized electronics of the tuner. Removing the tuner can reduce manufacturing costs, and certainly not much - the production cost of the tuner and its associated circuitry is approximately $4. So not too fast, the disappearance of the tuner may go through a long period of time, and hardly anyone notices it. If TVs no longer use tuners, then the choice of consumers when buying displays is critical. Their choice depends on what they plan to use: as an Apple TV? Use Roku set-top box? Smartphone-controlled field emission display (Fed)?
Once the tuner is removed on the screen, the screen is the same as the computer monitor used to view Internet video on the desk, except that the computer monitor may not have an integrated speaker. You may not call it a monitor because you may never connect it to a traditional computer. However, for those large flat-panel displays placed in the room, it is time to give them a different name from the TV. But what is good?
We may not have considered this issue for too long, because the large screens hanging on the walls of our rooms may soon cease to exist and replace them with a display that can disappear. When manufacturers first described giant flat-screen TVs that are now very common, they called this wall issue a "black hole." But they found that this problem will eventually disappear: As the life of the monitor continues to increase, the energy consumption gradually decreases, and one day people can keep the monitor on for display of family photos or favorite artworks. This is no longer an idea.
One way to make a disappearing screen is to use a flexible screen. LG released an OLED flexible display at the CES in January 2014, and at the 2016 CES demonstrated another 18-inch OLED screen that can be rolled into a 3 cm diameter tube. When not in use, simply roll up the screen like a blind. At present, this technology is extremely expensive: early users must pay more than 6000 US dollars. The cost of manufacturing a standard OLED display (which has been regarded as the ultimate video display technology for many years) has not yet reached such a low point. However, when such flexible screens enter the market, premiums may occur and they are widely promoted as the ultimate solution. Although no specific date was specified, LG has shown that it is confident that in the near future it will produce ultra-high-definition, curlable TVs with sizes of 55 inches and larger.
In the future, another interesting possibility is to make transparent displays. In January 2016, Panasonic demonstrated the prototype of a transparent display at CES. When the monitor is off, you can see the bookshelves or books on the wall behind it.
As a result, the future living room will look very different. Many people who are accustomed to using large screens do not want a large, dark rectangular screen to be the focus of their living room when they are not watching videos.
Of course, silicon chips that process video signals are unlikely to be flexible quickly, and it has been quite difficult to develop light-emitting display technology to such a soft, rollable shape. Conversely, it is likely that most video decoding and image processing electronics will be packaged separately from the display and wirelessly send all video data to the screen. Therefore, we will not only remove the TV tuner, but also quickly remove other electronic devices that make up the screen display. If you don't have a tuner, you don't have too many electronic devices, and you don't have a future screen that you can't use, you might think that the time has come for the TV to finally die.
But like life, the demise of the tuner won't happen overnight. I expect that for low and medium-priced TV sets, the tuner will remain in the TV for 20 years like a degenerative organ. Or, at the very least, it will be packaged separately from the monitor, and its introduction manual will never be opened. You will never use the signal cable. In the world of consumer electronics, many of the technologies you think are outdated will still persist for years or even decades before they finally disappear. This is especially true when the technology has a very large market for a long time. Is the so-called accumulation of difficult to change.
Think of Philips' compact cassettes. Tape cartridges have undergone 54 years of technological change since their invention. Although we already have better digital technologies such as CDs and chip recorders, you can still buy cartridges, players, and tape recorders. The 3D TV launched in 2010 to arouse people's replacement has not been able to capture the public's interest, and the available 3D content is also very few. However, as a standard, most TVs are still embedding that function in multimedia processors.
Similarly, there are two main reasons why RF tuner is likely to continue mass production in the next 20 years. In the global market (including parts of Europe, the Middle East, Africa and the Asia-Pacific region), radio broadcasting is still the dominant one. Elsewhere, although consumers have not used TV tuners for many years, they are still reluctant to buy TVs without tuners.
When we look at today, we can see the future. In the future, the living room and the room will no longer have a large rectangular black screen, but instead a rollable multi-screen display; in the future we will use a variety of gadgets to feed different types of video content to the wall. With the advent of new technologies, these gadgets will also be upgraded. This will surely benefit the environment, benefit our wallet, and benefit our lifestyle. For TV manufacturers, this will also be a good business model, forcing manufacturers to strive for more rapid innovation and differentiation in a highly competitive market.
When your grandchildren see pictures of today’s TV, they may be as surprised as your child sees a record player, thinking: What exactly do you use it for?
