Video has become more and more popular these days, almost everyone now owns a DVD player of some form within the homes, including dvd writers, Cellphone camera quality is increasing by the day, new nokia series phones with Carl Ziess lenses, it's all about quality.
HD - High Definition, TV or video is the talk these days, developed in the 90's the upgrade to analog TV. Those of you that probably know more about this would be our dedicated movie downloaders out there on the internet :)
HD format is most notably seen as 1080i50 = 1920x1080 with 50 frames per second, then 1080p = which would be the same as above except covers the following formats 1080p25, 1080p30, 1080p30, 1080p50 and now even 1080p60, as you guessed the last 2 digits equalling the FPS (frames per second)
Benefits of HD include that it has at least 2x the linear resolution compared to Standard Definition and is able to handle the 16:9 aspect ration without the stretching that the format 4:3 might face, therfore providing a more effective resolution. The image quality is clearer, so no more blurry or even fuzzy pictures/videos and is even 2 to 5 times more detailed than older formats! Lets not forget to mention the use of Dolby Digital that supports 5.1 surround sound.
But with all good things, there is 1 downside, due to the increase of picture and video quality, it requires a massive amount of data storage uncompressed, which is currently too expensive for the current market, therefore the use of MPEG-2 compression, making it slightly more affordable. The MPEG-2 is the most common compression codec used in the market today, although MPEG-4 AVC compression will allow recorders and broadcasters to save storage space and even a tremendous amount of bandwith. Those that have ever looked at downloading a HD movie online will have surely have noticed some file sizes of 25GB for an HD movie.
Formats Supporting HD:
HD DVD - High Definition Digital Versatile Disc
BD - Blu Ray Disc
Unfortunately both formats are not yet compatible with all players, yet still some hope as LG is set to release combo drives that will support both formats sometime this year.
New to the HD market - HD Camcorders. Sony and JVC are the first to release HD camcorders into the market, which offer HD quality stills and video! Not that the everyone has home systems to support these. But no fear! Chatted with Reg from the DVD Video department earlier today, and he is on top of this! HD Camcorder to DVD conversions is something our department is able to offer.
The interesting part will be how affordable this new technology with be in the months to come...As i sure would have to get a new PC monitor at home, or even wide screen to be able to spoil myself watching HD movies.
