High-definition or HD TV as we know it recently came into its tenth year of industry adoption. Its rich detailed picture resolution has been one of its biggest selling points as has the widescreen aspect ratio that makes the viewing experience so immersive. While broadcasters and media companies have already made the switch to the digital broadcasting and production format in the last 4 years, DVDs and Blu-ray DVD discs are still the best way to get a Full HD experience as most broadcasters are broadcasting in a different image scanning technology interlaced which makes the HD footage and content slightly different although this is not visible to the naked eye.
With a practical compromise between the needs of television and movies, the HDTV 16:9 aspect ratio has been adopted by major players including the DVD market which is one of the major motivations behind the purchase of an HDTV.
As far as digital broadcasting, broadcasters broadcasting digital channels offer more channels in one place and allow for greater interactivity between the viewer and the broadcaster. This allows users to be able to view electronic program guides, subtitles and other features that have been available to most satellite and cable users for some time. Because digital broadcasting was first introduced on the DVB (Digital Video Broadcasting) platform adopted by satellite and cable TV providers, it is no surprise that they have the largest selection of programming and content in HD. Also most satellite companies seem to have an advantage over cable providers. This is because of the DVB platform which is standard and the set boxes sold by these providers. Cable and terrestrial broadcasters are playing catch up as well now offering their own high-definition (HD) receiver/tuner and HD personal recorder/digital recorder (DVR) devices. In addition the two gaming console leaders, Microsoft and Sony provide HD playback capabilities on their Xbox 360 and PS3 respectively.
The options of HD content do not end there, online video sharing sites like YouTube, streaming services such as Netflix, Amazon and others all have important partnerships with HDTV makers and their services are widely available.
Although some may view HDTV as still in its early stages of growth, the widespread adoption and technologies needed to help HD reach its boundaries are in place and all that remains to be seen is where HD will go next.
