High-Definition Television, also known as HDTV, is digitally broadcast television, which has slowly replaced analog versions with higher resolution and better image quality than standard-definition TV.
As bandwidth and standards for television programming have changed over the decades, high definition television options have been adopted by the Federal Communication Commission and TV industry.
With limited initial standardization, HD’s early adoption was slowed by technical and economic factors. It was only distributable by satellite with recording and reproduction of signal proving to be a technical difficulty early on. Japan was the first country to successfully offer public broadcasting in high definition, and in 2007 the country abandoned analog service.
HDTV came to the United States in the 1990s and was first introduced by the Digital HDTV Grand Alliance, a conglomeration of television companies. The first high definition broadcast occurred in 1996 in Raleigh, North Carolina and later launches followed. The TV system was first broadcast in 2004 with the launch of the HD1 channel and broadcasting of its Vienna New Year’s concert.
High-def TV offers greater picture quality and higher image resolution as a result of three defining characteristics. These include frame size, scanning system and frame rates that are specific to the higher-definition programming and not possible with analog television.
Potential HD viewers will need to invest in an HD-specific television set and any other equipment that may be necessary to view it in their home or business. This can mean anything from cable boxes to tuners, and should be confirmed with cable companies.
Amongst worldwide TV viewers and customers, one of the most well-liked features of HDTV is recording capabilities. TiVo is the most famous version of such a feature, and it allows you to record and view more than one program at the same time. This also allows viewers to record programs while watching others at the same time.
Due to America’s nation wide switch to digital viewing capabilities, the Federal Communications Commission has regulated the market, forcing cable providers to offer set-top boxes that allow them to record and store information upon signing up for service.
Traditionally, these television products have been available for in-store purchase with in-home installation. Now, however, online purchases are becoming more common and available around the country.
High-def TV sets can range in price from as low as four hundred dollars to more than five thousand dollars, depending on the retailer and model. Some have been sold for as much as fifteen thousand dollars. It is expected that as high-definition television becomes increasingly popular, prices will begin and continue to drop, making it easier and more attainable for most consumers.
There are several advantages to HD. This includes better picture quality, regardless of the screen size. Editing of the pictures allows for better video progression as opposed to the cutting short of frames in analog broadcasting. Also, stations can air several signals with the same bandwidth, also known as “multicasting”. This new system also allows for additional and interactive content. The major disadvantage of this new system is that it is not compatible with analog TVs, which cannot decode or display the signals. This requires converters or the purchase of a new television set.
