扣掉PS3, BD的機器銷售是輸HD-DVD的
看過不少專家討論HD-DVD 跟BD 可能最後又變成DVD+R DVD-R的狀態
變成一台機器吃兩個.
消費者沒得利, 廠商也麻煩...
HD-DVD PLAYER在美國不少店家最近都有舊MODEL 99.99 新MODEL AFTER REBATE 129.99
相對的BD機器還是很貴 都是靠PS3來賣播放機-_- 說真的除了PS3 其他BD播放機還真的買不下手
HD-DVD我最喜歡的一點是沒有區域碼..不像我的PS3分三區..
HD-DVD 跟BLUE-RAY的比較到11/2007 SOURCE WIKIPEDIA~
The primary rival to Blu-ray Disc is HD DVD. As of November 2007, HD DVD has the advantage in maximum disc capacity (51 GB triple-layer versus 50 GB dual-layer), but no titles have yet been released on the triple-layer format.[100] It is unknown at this time whether the final specification will be compatible with current players.[101] As of November 2007 44% of Blu-ray titles use the 50 GB disc and 56% use the 25 GB disc[102] while almost all HD DVD movies are in the 30 GB dual layer format.[103]
In terms of audio/video compression, Blu-ray Disc and HD DVD are similar on the surface: both support MPEG-2, VC-1, and H.264 for video compression, and Dolby Digital, PCM, and DTS for audio compression. The first generation of Blu-ray Disc movies released used MPEG-2 (the standard currently used in DVDs, although encoded at a much higher video resolution and a much higher bit rate than those used on conventional DVDs), while initial HD DVDs releases used the VC-1 codec. Due to greater total disc capacity, the Blu-ray Disc producers may choose in the future to utilize a higher maximum video bit rate, as well as potentially higher average bit rates. As of November 2007, 41% of Blu-ray Discs are encoded in MPEG-2 while AVC is used on 33% discs and VC-1 at 26%.[102]
In terms of audio, there are some differences. To ensure backwards compatibility with older receivers with Dolby Digital decoders, Blu-ray Disc allows conventional Dolby Digital audiotracks at 640 kbit/s and this is the primary audio track for 33% of Blu-ray titles, while it has gone unused for HD DVD titles. The newer Dolby Digital Plus is mandatory for HD DVD players at 3 Mbit/s (which is used for 90% of HD DVD titles), while optional for BD players with support at a bitrate of 1.736 Mbit/s for mixes that require more than 5.1 channels (has only been used on two titles).[104] Both formats optionally support DTS-HD High Resolution Audio, a lossy compression scheme that extends the core DTS audio for better fidelity but yet is still not lossless.
As for lossless audio, 43% Blu-ray Discs have 5.1 LPCM uncompressed audio,[102] which is the only lossless format that is mandatory for Blu-ray players. Blu-ray Disc also has optional support for Dolby TrueHD lossless encoding of up to 8 channels of audio, and DTS-HD Master Audio, a lossless encoding of up to 8 channels of audio.[105] As of November 2007, 7% of Blu-ray Discs are encoded in Dolby TrueHD while DTS-HD Master Audio is used on 12% on discs.[102] In total, 60% of Blu-ray Discs have either uncompressed or lossless audio. HD DVD also supports LPCM, but unlike Blu-ray, it has mandatory support for Dolby TrueHD, although only 20% of HD DVD movies have lossless audio.[citation needed]
Both HD DVD and Blu-ray Disc support the 24p (traditional movie) frame rate, but technical implementations of this mode are different between the formats. Blu-ray Disc supports 24p with its native timing, while HD DVD uses 60i timing for 24p (encoded progressively, replacing missing fields with "repeat field flags"). Decoders can ignore the “flags” to output 24p.[106] There is no impact on picture resolution and minimal impact on storage space as a result of this, as the HD DVD format often uses the same encoded video—it simply adds notational overhead.
There is no Region Coding in the existing HD DVD specification, which means that titles from any country can be played in players in any other country. Compared to that a significant percentage of Blu-ray disks have Region Coding and will only play in players sold in the corresponding geographic region. Specifically many Blu-ray disks sold in the US will not play in Blu-ray players sold in Europe.
Since both formats launched in the spring of 2006, an estimated 4.98 million high-definition discs have been sold, including 3.01 million in Blu-ray and 1.97 million in HD DVD through the end of September.[107] However, those figures are dwarfed by the sales of regular DVDs. Combined, the two high-def disc formats accounted for only 2.5 % of overall disc sales during the first half of 2007.[108]

...(恕刪)歐美市場現在bd的電影在大特價
還出現bd電影比dvd便宜,BD片子賣的沒比較多就是有鬼了
HD-DVD的片子完全沒打折
另外要引述別人的統計
麻煩引列原來的出處
不然你說了算就好啦?
每次討論到BD vs HD 常常有奇怪的理論出現
BD的軟體優勢不是感恩節之後才冒出來的
以下數據顯示今年到現在，雙方差距約為2:1，購物季節的第一周則逼近3:1
HIGH-DEF MARKET SHARE (11/25/07 - Nielsen/VideoScan):
Week End. 11/25 Blu-ray Disc: 72 HD-DVD: 28
Year to Date Blu-ray Disc: 65 HD-DVD: 35
Since Inception Blu-ray Disc: 62 HD-DVD: 38
資料來自http://www.thedigitalbits.com/ 以及http://www.homemediamagazine.com/的報導
實際調查單位是Nielsen/VideoScan
最後再附加兩點
1. 如果BD的銷售量來自於特價，HD電影也可以搞特價，看能不能力挽狂瀾？ 反正$99機器都豁出去了
2. BD也有硬體廠商的支持優勢，請問除了T牌外，有哪家主要廠商押寶HD機器？
