Good picture thanks to HD format
Video HDTV is on the rise - a new standard that will capture the imagination of film-makers and home cinema fans.
Video HDTV is on the rise - a new standard that will capture the imagination of film-makers and home cinema fans You don't have to be a visionary to imagine that home networks will soon be standard in our apartments and houses. The picture and sound will be transmitted wirelessly from a central server to the corresponding output device. The picture quality on televisions will also improve significantly in the future - HDTV, high-definition television, is the new standard. The significantly better picture quality is made possible by the HD (High Definition) format, which has a higher resolution - provided the television set is capable of displaying the high resolution. HDTV displays five times more pixels on corresponding television sets and is broadcast in the 16:9 width:height aspect ratio that was already widespread with the advent of the DVD. If you want to enjoy the higher resolutions, you have to invest in new televisions or projectors on the receiver side. According to Sony Switzerland, HDTV is now gaining ground: "More than 100 television stations in the USA regularly broadcast in HD format," says Marco Di Piazza, Marketing Director at Sony Switzerland. The German channels Pro 7, Premiere, RTL and Sat 1 are already producing for high-definition television sets or are in the starting blocks. "The significance of HDTV is compared to the introduction of color television," explains Di Piazza, enthusiastic about the improved picture quality.
But the new picture quality will not only be available on home television sets. Just under a week before this issue was published, Dr. W. A. Günther Media Rent AG presented a novelty at Schluefweg in Kloten - where the Kloten Flyers normally battle for ice hockey points. For the first time in Switzerland, a shareholders' meeting (of Credit Suisse) was held with images in HD format and recorded with HD cameras.
But HDTV is already being used in other areas too: Mystery Park in Interlaken, for example, has been using the high-resolution format for its projections for some time now.
HDTV - and the requirements
Special equipment is required for recording, processing and distribution so that high-definition programs can be broadcast. When it comes to recording technology, video producers need to invest their money in new, HD-compatible cameras and camcorders. The camcorders previously only available from Sony, JVC and Panasonic record in HDV (High Definition Video) format. There are now two options here: On the one hand, it is possible to record in HDTV quality (i.e. in HD format) and on the other, data compression format MPEG-2 (HDV).
The question of which video editing software can now be used to edit the recordings depends precisely on the step selected during recording: If the footage was recorded in true HD format, the recently released Final Cut Pro 5 software from Apple can be used, for example. If, on the other hand, MPEG compression is selected, then the choice of software is significantly greater: with iMovie HD and Final Cut Express HD, Apple also offers two solutions for editing film material in HDV format for this segment. If you add the HDV plug-in to Adobe Premiere Pro 1.5, you can also import and edit video content that was recorded with corresponding HDV digital cameras and in MPEG-2 format.
Apple's success and efforts in the video sector have apparently not gone unnoticed. It has been known since April 17 that the companies Adobe, HP, Intel, Microsoft and Dell want to establish a new standard called OpenHD. Adobe and Dell, for example, want to launch a PC optimized for video production that does not require special plug-in cards.
The distribution of video content refers to the output to corresponding data carriers. As with the VHS and Video 2000 format in the days of the good old video recorder, two interest groups are vying for the "standard" in recording. The rivals in the HDTV environment are Blu-Ray and HD-DVD (see box). For both systems, recorders, players and the corresponding media are on the verge of market maturity from several suppliers. In both systems, the data carriers are scanned or recorded with blue lasers, but differ in their structure. While the HD DVD can record up to 30 GB of data, the Blu-ray Disc (BRD) can record up to 50 GB. Sony is already working on 200 GB BRDs, in which the data is recorded in several layers. It remains to be hoped that the Blu-ray consortium led by Sony and the HD DVD consortium led by Toshiba and NEC will agree on a common standard before the market launch.
HD: From 33 to 100 in 2 yearsThe discussion about distribution will probably not stop HDTV as a whole. On the contrary, the growing importance of the HD format at European level can be seen in past and upcoming international sporting events: At the Olympic Games in Athens, a third of the broadcasts were produced in HD format. The upcoming Winter Olympics in Turin will be recorded in full in HD format by the tpc production center of Swiss television SF DRS - it is not yet clear when HDTV will be broadcast by SF DRS. The Football World Cup in Germany will be recorded - and partly broadcast - in HD, and HDTV will even be the official production standard for the 2008 Olympic Games in Beijing.
The film and video industry now has a new standard. In contrast to the two fronts in distribution (Blu-Ray versus HD-DVD), the question is no longer whether the new HDTV standard will prevail - but when and how quickly.
The catch with the new quality is the investment required by video producers. In addition to HD-ready editing suites and cameras, consumers also need to update their output solutions (players/recorders and media), televisions and projectors if they want to benefit from the new picture quality. HD-ready televisions are already available on the market.
Video distributionBlu-Ray: Single-layer Blu-Ray discs can hold up to 25 GB of data - dual-layer discs offer space for up to 50 GB. The discs, also known as BD-ROM or BRD, can store up to four hours of high-resolution video. In contrast to the red lasers used in DVD, DVD±R, DVD±RW and DVD-RAM, Blu-Ray recorders use blue-violet lasers (405 nm) - from which the name Blu-Ray is derived. Like the familiar CDs and DVDs, the new media are 12 cm in diameter. The Blu-Ray disc format is currently favored by leading suppliers in the computer and home electronics industry. The companies Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson are among the members of the Blu-Ray Disc Association.
HD-DVD: HD DVD also uses blue lasers and is 12 cm in diameter. In technical terms, it is a further development of the successful DVD and can be produced in almost exactly the same way. The most important developers of HD-DVD are Toshiba and NEC. There is a 15 GB read-only version of HD-DVDs and a re-writable version that can hold up to 20 GB of data - dual-layer data carriers can hold 30 (read only) or 32 GB (re-writable) of data or film content.
