Spicy, colorful, louder: HDTV really comes this time?
HDTV – from most still confused with the digital antenna television DVB-T, but this is not HDTV-BiGig in Germany, has significant image difficulties thanks to HDCP copy protection. Another problem: The chips that can be decoded the new signal emitted in MPEG 4 were not finished in time. Instead of the 1. November 2005 Premiere HDTV started only on the 28. January 2006. Nevertheless, the industry is satisfied.
HDMI should the "Digital Scart Connection ", which are transferred in addition to picture, and even in better quality than today’s optical digital connections. HDMI builds technically on DVI (Digital Visual Interface) for monitors; The sound is specifically provided. What is also intended and the whole thing is in question again, the copy protection function HDCP (High Bandwidth Digital Content Protection) is. This leads to the high-resolution screens without copy protection function can not reproduce the new image, which caused the buyers who have become active in the chance of mistreat.
The HDMI connector: almost as small as mini-USB, past is the chunkiness of Scart
It is unclear the possibility of recording HDTV signals. In the long term, there will be at least satellite reception with built-in hard drive as a buffer, according to Hans Seger from Premiere from summer 2007. Since HDTV generates significantly large amounts of data than normal television, however, these devices are also limited with coarse hard drives only limited memory options. The recording on DVD or their successors Blu-ray disc or HD-DVD, on the other hand, is technically well intended, but in practice, however, the copy protection will fail, which is currently both new systems from the market resignation: as in the audio copy protection SCMS (Serial Copy Management System), which should actually only prevent any more and more copying a copy, but due to false signaling on the part of the content suppliers usually copying the same completely prohibited, is already foreseeable that HDCP is believed in a similar manner. In addition, there are no reasonable systems to distribute the digital signal from and to all parties involved. This problem also shares with digital audio signals that are not so uncomplicated as their analog equivalents.
Dr. Rainer Hecker, Chairman of the Supervisory Board of the Company for Entertainment and Communication Electronics (GFU) and at the same time Chairman of the Executive Board of the television manufacturer Loewe AG, but sees for its industry that produces the hardware necessary to watch good future prospects: "The future of television is flat".
The program quality is not meant, how to probably suspect – this is already flat – but the screens. And these are greatly more expensive in the new standard than before. The transfer is more expensive – instead of the previous MPEG 2-HDTV transmissions, in which only one station is adapted to a today’s digital satellite transponder instead of eight to twelve in normal television form, it is with MPEG 4-HDTV at least three Channels. At Premiere, this HD movie, HD theme and HD sports. While the sports and movie channel should be equivalent to the previous sports and movie offer, HD theme will be a high-resolution version of the discovery channel. In contrast to the HDTV program of SAT 1 / PRO 7, which represents only a high-internally polished normal image from a few contributing, Premiere sends in all three channels genuine HDTV, albeit with the repeat rhythms that are carried out in the payment television. Also, previous TV reception cards for PCs for the new system are not suitable, it must be so-called DVB-S2 cards.
What is saved during transmission costs the hardware more
On the other hand, when the costs should increase only slightly, is the production: from 10 to 20% additional costs, since the main costs are not technically conditioned here, but for actors, commercial ballpieces or documentary filmers. That then a more modern equipment is to be used, new investments, which do not even have to print the public broadcasters, is, but this changeover process is sometimes already passed or is – for example, in the HDTV scanning of films – relatively quickly replenished.
In the picture, HDTV brings the qualitative leap from today’s television image (at PAL only slightly more than VGA resolution, with NTSC exactly VGA resolution) to a resolution of a maximum of 1920 x 1080 pixels, which already corresponds to a proper digital photo. The colors should also be a little brilliant: from today’s strongly engraved PAL or. SRGB color space you do not want to go to the professional Adobe RGB color space, as this print was developed and only very expensive screens can reproduce this, but at least the origin of the introduction of American color television planned NTSC color space of 1953 ; This was reduced later, as the former screens were simply not able to reproduce the intended color.
The effect will be that the colors are slightly differentiated at HDTV and not so bright colorful as today’s television. However, the color sadness must be set stronger accordingly, as the image is otherwise only pale, and the screens must also really participate. If you look at HDTV on a usual computer screen, either get a pale picture or deserve the color variety again – the strong saturated hue then melt together.

However, how many spectators can be used today the improved color quality, is questionable – in a field test of Premiere, the better color reproduction should be noticated 85%. Better tone was also reported in the field trial, which HDTV can not yet get true today, even if the striking Dolby procedures are expanded here again: Playbackates that dominate these new tone procedures, there are still little as appropriate receivers or shipments.
Probably these for premiere very flattering results were more likely to influence that the spectators generally had to buy a new device and with this already without HDTV had a better picture and a better tone than with the old TV. However, customers seemed to be overburdened by the beautiful new television world: One of the Premiere employees Action was namely that digital over HDMI supplied images in standard format 4: 3 no longer distort at the push screen 16: 9 distort , as is apparent today many spectators to fully exploit their beautiful widescreen TV, even if no corresponding signal is sent and so politicians and showstars are much thicker than they are already anyway.
From 2004 to 2005, the paragraph of LCD televisions in Europe has increased by 155% in Germany, in Germany even by 173%. The more efficient, but flickering and significantly more electricity than LCDs consuming and less high-resolution plasma displays increased by 112% throughout Europe, but in Germany, however, to be stately 250%. However, she was allowed to cross her wedding. And even if Really HDTV-proof displays with copy protection function are only recently on the market, they have already covered the half of the market in 2005 in Germany with tendency to 3/4 towards the end of the year.
Hard disk in the TV
The HDTV receptionist and also the hard drives for caching shipments from separate set-top boxes could become an integral part of televisions. With the luxury brand Loewe this is already common today, 1/3 of the gates should already be so deserted there.
The first HDTV receptioners for the premiere broadcasts are now available from PACE and Humax, while Philips, which actually were the first to have the premiere, have problems with the decoder chip used, which is not yet ready. The current business goes the manufacturer’s steam through the rags, but in the duration, the wait for Philips has been worth it, because the one-chip solution is natural in the production cheaper than the gates of competition, which still need several chips.
At Premiere, the HDTV subscription costs between 12 and 15 euros in addition to an existing premiere subscription. The film studios do not require additional licenses specifically for HDTV broadcast, but the activation of the copy protection. On the other hand, sports and documentation can be broadcast until further harvesting.
In the long term, HDTV should also be widespread in the cable stronger, the viewers of the payment television Premiere previously distribute themselves for half to cable and satellite, but the HDTV broadcasts are 80% on satellite and only 20% in the cable, so there is still catching demand.
