What is a Digital Converter Box?
After transition from analog to digital broadcasting, many users have faced a problem: a great number of channels they used to watch were not supported in old TV sets. They just had no capacity to receive such a signal. As a rule, most modern TV sets are already equipped with special tuners, but they are not, an acquisition of a new panel is not cheap. You can solve this problem by purchasing a digital converter box. This device receives a digital signal further converted into an analog one. Thus you are able to enjoy the newest broadcasting signal still using your old TV set.
For those who wish to expand the functionality of their TV sets significantly and make it really smart, we suggest considering a streaming media player. But to improve the received signal you'll also need a high-quality TV antenna.
What Features to Compare
When selecting a digital converter it's necessary to decide on the broadcasting support you will need. As we know, a digital converter serves for decoding an ATSC digital signal into an NTSC analog one. But if you still want to receive an analog signal coming from local low-power broadcasters that don't intend to transit to a digital format, you should check if there is an Analog Pass-Through feature. Thanks to this feature, the analog signal will pass directly to the TV set. If you also want to watch digital cable channels, you'll need to make sure you have a tuner in a QAM standard. It's worth noting that in this case, you will be able to watch uncoded channels only.
It's very important to take into consideration the broadcasted image resolution, as it affects the quality and at the same time compatibility with a TV screen. If your TV set has a standard SDTV screen, no need to overpay for the tuner supporting HDTV video signal reception. For example, if your TV screen is 1080p, pay attention to the tuner, which should support the same HDTV (High Definition) standard. Older TV models can have 720p and 480p resolution, so tuners with EDTV (Enhanced Definition) and SDTV (Standard Definition) formats support respectively will be needed.
While speaking about the tuner features, we normally mean additional functions like a built-in USB multimedia player, which allows you to play back digital content from flash drives and portable hard disks. The recording enables you to save video live to the same external memory. The next function is the creation of your favorite channels list for a quick access. The closed caption function helps display it if necessary. Other essential functions are parental control, auto-tuning, sleep mode, and the capacity to switch the device on and off at a certain time.
Interfaces and Multimedia Processing
And in conclusion, you should check the tuner connection to the TV set. It's recommended to use an HDMI connector to achieve the highest quality. If your TV doesn't have it, make sure you have analog composite audio/video ports. As for the connection with external memory, a USB connector is required, and for the antenna — an RF port. The USB multimedia player and digital signal compression standards support plays a great role as well. It's better to give preference to the tuners supporting AVI, DAT, VOB, MKV, MJPEG video, for the music it should be MP3, AAC, MP4, and for images: JPEG, BMP, PNG. In modern tuners MPEG-2 or MPEG-4 video compression technologies are generally used, therefore such devices are usually called digital television decoders.

The history of the digital television standard in the USA originates in the distant 1987. This happened after Japan and Europe had created their own high-definition TV systems called MUSE and HD-MAC. To answer that, the US experts in this field decided to hold a national contest for the best high-definition TV system project for its further adoption as a national broadcasting standard. The result of such a bold decision was the establishment of a special body: ATSC (Advance Television Systems Committee), which is, by the way, the only body even nowadays that defines and regulates digital television broadcasting standards in the United States and Canada. Yet in terms of transition to the digital TV, the USA occupies a leading position. Despite the fact that originally the government's decision had caused an uproar of indignation and panic, many people had got ready for this format in advance, and most of them were elderly Americans. Unprepared were only 2.8 mln American families.

It's quite difficult to surprise anybody with digital television today. But few people know how the process of transition from analog to digital broadcasting advanced. The turning point in this history was the decision taken on February 17, 2009, by the US Congress about the termination of analog broadcasting by all the TV stations. The very transition process required conversion of about 1800 high-power transmitting centers. Among them, there were 380 public and 1378 private ones. It's noteworthy that many cable operators continued to broadcast in analog format additionally, that still allowed the users of analog television to watch their favorite channels without any tuners. At the same time, e-stores were forbidden to sell TVs without digital tuners. So many electronics manufacturers started mass production of various TV tuners, which converted a digital signal into an analog one to let people watch their old TVs. All the while NTIA (National Telecommunications and Information Administration) tested and selected the best and at the same time inexpensive tuner models, that cost $40-70 afterward compensated by the state. For the television reform, the government allocated about 1.5 bln Dollars. It's interesting, people got special $40 coupons, 1-2 per each family, to purchase these very tuners. Many sellers had to be certified for participation in the program. At the present moment, the US government stopped issuing coupons.
