IDTV stands for Integrated Digital Television, which is a specific type of television that has a digital tuner inside of it. This includes any television that receives a digital signal through a variety of different types of media without the addition of peripheral components. In other words, an integrated digital television does not need a set top box to convert digital television signals; instead, this functionality is built directly into the device. IDTV offers enhanced technology that is integrated directly into the television set to provide better quality viewing.
The digital connection can be provided by a telephone line or cable service, allowing viewers to enjoy a range of television viewing options. Most TVs allow for analog signals to also be received. Some TV sets require a set top box to convert the analog signals so they can be received effectively. Users can choose to purchase other hardware that provides them with more or different viewing options other than those already provided by the digital set.
Digital television offers features, including improved reception and a widescreen picture, which allow for great viewing quality. The advantages of enhanced technology provide an array of new features that far exceeds that of the traditional analog system of the past. IDTV uses the same media features as that of the Internet, and in some cases, the integrated digital TV contains a media extender. This piece of hardware provides the ability to connect the digital television directly to a computer or the Internet.
In addition to the wide screen and high quality reception, electronic program guides (EPGs) are yet another potential feature. EPGs allow viewers to search for specific programs and then get an overview of the show to decide if they want to watch it. They also have the capability to schedule programs in advance or use the personal planner features to be reminded when certain shows are airing.
Interactive television is also sometimes available. With this functionality, viewers can actually interact with content while they are viewing it. They can view sports scores or click to another channel to find additional information about actors or statistics that may be relevant to the program. These options enhance the experience of television and allow the viewer a significant level of control over his or her television options with just the click of a button.
