just use whatever medium you want...

If you pick up this months issue of DJ Times, (the one with Gabriel & Dresden on the cover) they discuss it alot. They have a lot of opinions from a lot of DJ's. It basically came down to this: records will always be here because someone will always use them, but a lot of up DJ's prefer to use laptops and vinyl scratch. With advances in technology you can do so much more.
um, tv does have standards
hdtv is a standard, the ratio size of images are all standards
input connections to TV's are all standards
cd is compressed and that's why is sounds cold and clipped because after a certain level sound and ambience can't be played.Cd's are limited and are on their way out as a future medium like cassette. However new medium is coming that will be better such as dvd audio and super cd , plus they offer copy protection which I assume is something record companies are very much interested in.
DVD-Audio/SACD
| quote: |
| While Panasonic and others are touting the virtues of DVD-Audio, SONY (in partnership with Philips ) is pushing its own format, SACD (Super Audio CD). Ironically, it was SONY and Philips that also developed the current CD format. Based on Direct Stream Digital Recording (DSD), SACD provides for more accurate sound reproduction than the Pulse Code Modulation (PCM) used in the current CD format and DVD-Audio. With DSD, the music is not compressed, thus all the musical information is retained in the digital signal, with no artifacts or missing information. Thus, SACD is the only digital music reproduction that can truly be said retains the analog characteristics of the source throughout the process. While the current CD format is tied to 44.1 kHz sampling rate, SACD samples at 2.8224 MHz.. Also, with a storage capacity of 4.7 gigabytes per disk (as much as a single sided DVD), SACD can accommodate separate stereo and six-channel mixes of 100 minutes each. Although not as large a storage capacity as DVD-Audio Discs, SACDs do have capacity to include extras such as album graphics, still photos, printed lyrics, liner notes, or even sheet music of the music content (however, none of these features was a part of the demos I attended). SACD players are also backward compatible with conventional CDs, and SACD disks can be dual-layer discs with PCM content that can be played in standard CD players. In other words, the same disk can hold regular CD versions of its SACD content. That means that you can invest in dual-format SACD's to play on your current CD player now and then access the SACD content on the same disc later. One failing of SACD up to this point however, is that it has been strictly a two-channel stereo format. Although this has garnered rave reviews from Audiophiles, with all the emphasis on the home theater listening enivornment, SACD has limited its appeal to the potential mass market relative to that of DVD-Audio. However, perhaps in response to the competition of DVD-Audio, both Philips and Sony (the main proponents of SACD) have announced a line of SACD players that will be multi-channel capable and new multi-channel recordings will also be released. Philips unveiled their player (SACD-1000: $2,000) at CES in a persausive demonstration revealing the true depth of a multi-channel SACD recording when compared to a traditional CD and two-channel SACD of the same content. Lastly, unlike DVD-Audio players, which are also DVD-Video players, most SACD players up to this point are Audio-only players. So, in response to DVD-Audio, many new SACD players will also be able to player DVD-video discs as well, giving SACD players more flexibility in a home entertainment setup. Chances are, both DVD-Audio and SACD will be here for awhile, and with the CE market being so large, both may survive. However, before making your buying decision, make sure you not only take a good listen, but be aware that software titles (although arriving a steady rate) just number in the hundreds and most are remasters of older material. However, many artists are beginning to sign-on for DVD-Audio and SACD recording projects. Software titles generally run $25-30 price range. For a good online resource of both DVD-Audio and SACD titles, check out SurroundMusic.net, an affiliate of Widescreen Review Magazine. Starting in mid-year, you may start seeing an aggressive advertising push for both DVD-Audio and SACD, perhaps with some software title offers as well. With the investment that the manufacturers are making in these formats, as evidenced by a heavy CES presence, they will definitely need to do something to jump-start sales once products appear on the shelves en masse. The manufacturers have not only to convince the public of the sonic improvements of DVD-Audio and/or SACD, but get the public to once-again, reach into their pocketbooks for yet-another component to add to their systems. If you are planning to replace (or make a first purchase) of a CD or DVD player, definitely consider the new generation of DVD-Audio or SACD players (both will play DVDs and CDs as well), the choice may be easier than those of you that may have just poured money into a DVD player or CD player (especially on the high-end). It remains to be seen whether DVD-Audio or SACD will become the eventual successor to the CD. I must say, that after listening to demonstrations of each format with a variety of systems, it is hard to tell any actual sonic quality differences between the two formats (at least in the environments they were demonstrated in). DVD-Audio seems to have an early lead in both hardware and software availability (along with more manufacturing partners). One the other hand, with both SONY's huge music library and Philips' worldwide marketing muscle, SACD could catch up fast. No matter which format becomes the eventual marketplace leader, the age of the CD and two-channel stereo may becoming to an end. This concludes the third in my series new home theater technologies introduced at this year's CES. Stay tuned for more in this series, including new TV-display technologies, and more. |

| There are a number of differences between DVD-Audio and SACD. DVD-Audio is a member of the DVD family, and is closely associated with DVD-Video. DVD-Audio offers high resolution, multi-channel audio plus extra content such as video and still images. These discs can also include DVD-ROM content. DVD-Audio is a multimedia format, playable on all DVD players. Future discs may include a CD layer/side. SACD was designed as a higher resolution audio only format with no extra video or still images and will not play on DVD-Video or DVD-Audio players. SACD offers backwards compatibility with CD audio players but discs are not playable on DVD players (except the CD layer). Each format is available in three versions: single layer, dual layer and hybrid. Layers Single Layer Dual Layer Hybrid CD audio No No Yes DVD-A/V 4.7 GB A/V 8.5 GB A/V 4.7 GB A/V SACD 4.7 GB Audio 8.5 GB Audio 4.7 GB Audio Note that a CD audio layer is present only on hybrid versions. DVD-Audio hybrid versions are likely to be double sided, with the CD layer bonded to the DVD substrate back to back. Such discs are not yet in use, except in small quantities. The following table compares all three formats DVD-Video, DVD-Audio and SACD. DVD-Video DVD-Audio SACD High resolution No Yes Yes Multi-channel Yes Yes Yes Audio coding DD/DTS/PCM PCM/MLP DSD & DST Max bit rate 6.144 Mb/s 9.6 Mb/s - Video and stills Yes Yes No Menus Yes Yes No Copy Protection Weak Strong Stronger Plays on: DVD-V player DVD-A player SACD player CD player Yes Yes Yes** No DVD-Video* Yes ? Yes (hybrid) No No Yes Yes (hybrid) *Most DVD-Audio discs include DVD-Video content so will play on all DVD players. **Most SACD players also play DVD-Video discs. Direct Stream Digital (DSD) vs PCM One of the main differences between DVD-Audio and SACD is that while the former uses PCM (pulse code modulation) to code the audio, SACD uses DSD. PCM recording has been used for the compact disc for the last 20 years and codes the audio as samples. However, it has been recognised for some time that the CD does not offer a high enough quality to satisfy audiophiles. DVD-Audio uses PCM at up to 96 kHz (192kHz for stereo) sample rate and up to 24 bits per sample. SACD uses one-bit DSD (Direct Stream Digital) at a bit rate of 2.8224 Mb/s which is 64 times the CD sampling rate of 44.1 kHz. DSD is simpler than PCM and removes the need for steep decimation and interpolation filtering. But independent studies have concluded that DSD (also called 1-bit sigma delta) suffers from a number of problems that makes it unsuitable for archiving and, possibly, distribution. These problems include non-linearity and high frequency noise. DSD is also not easy to edit without converting to PCM. One conclusion is that DSD makes digital to analogue conversion easier and, in the past, cheaper, but PCM provides a more reliable and accurate representation of the music. In practice both can provide a very high quality level that should be acceptable to most audiophiles. |

| [DVD Audio DVD audio and DVD video are different formats. DVD audio discs and players are relatively rare right now, but they will become more common, and the difference in sound quality should be noticeable. In order to take advantage of higher-quality DVD audio discs, you will need a DVD player with a 192kHz/24-bit digital-to-analog converter (DAC). Most DVD players have only a 96kHz/24-bit digital-to-analog converter. So if you want to be able to listen to DVD audio discs, be sure to look for a DVD audio player with a 192kHz/24-bit digital-to-analog converter. DVD audio recordings can provide far better sound quality than CDs. The chart below lists the sampling rate and accuracy for CD recordings and the maximum sampling rate and accuracy for DVD recordings. CDs can hold 74 minutes of music. DVD audio discs can hold 74 minutes of music at their highest quality level, 192kHz/24-bit audio. By lowering either the sampling rate or the accuracy, DVDs can be made to hold more music. A DVD audio disc can store up to two hours of 6-channel, better than CD quality, 96kHz/24-bit music. Lower the specifications further, and a DVD audio disc can hold almost seven hours of CD-quality audio. Specification CD Audio DVD Audio Sampling Rate 44.1 kHz 192 kHz Samples Per Second 44,100 192,000 Sampling Accuracy 16-bit 24-bit Number of Possible Output Levels 65,536 16,777,216 In an audio CD or DVD, each bit represents a digital command telling the DAC what voltage level to output (see How Analog and Digital Recording Works for details). While an ideal recording would follow the raw waveform exactly, digital recordings sample the sound at different frequencies, and therefore lose some of the data. The graph above shows how the highest quality DVD audio compares to CD audio. You can see that DVD follows the signal more closely, but it's still a long way from perfect |

the same thing was said yeard ago. the digital side of things have come into it more since the devolpment of CD turntabela, downloading music. Vinyl still has years and years!!!
I think the current trend is for cd and dvd media to slowly die down because of their inherent limitations but because of their huge popularity and presence in the consumer market any replacement that comes out must support legacy cd and dvd media if they want people to adopt any new technology. If the next media is based of blu ray disc than it should be no problem since it has the exact dimensions and blu ray manufacturers which is practically all the major electronic company all have said to support cd and dvd media.
When blu ray starts coming out outside of Japan next year, it will probably mean the of cd and untimely end of dvd. But the music enthusiasts should rejoice for they can't fathom the kind of improvement they will witness when new media starts coming out. The cosumers will start to see discs of 25 and 50 GB at first with plans of 100, 200 and 400 GB later.
Sony is developing 200GB Blu-ray storage
| quote: |
| Sony Corp. will announce next month that it developed an 8-layer version of the Blu-ray Disc that is capable of storing 200GB of data, according to a company spokesman. The announcement will be made at the International Symposium on Optical Memory 2004, from Oct.11 to Oct.15, in Jeju Island, South Korea, according to Sony. The company further plans to commercialize a 4-layer 100GB version in 2007, said Sony spokesman Taro Takamine. |
