Origins
Sony started
two projects in collaboration with Philips applying the
new diodes: UDO (Ultra Density Optical)
and DVR Blue together with Pioneer
The first DVR Blue prototypes were unveiled at the CEATEC exhibition in October 2000 by Sony A trademark for the "Blue Disc" logo was filed February 9, 2001 On February 19, 2002, the project was officially announced as Blu-ray Disc, and Blu-ray Disc Founders was founded by the nine initial members.The first consumer device arrived in stores on April 10, 2003: the Sony BDZ-S77, a $3,800(US) BD-RE recorder that was made available only in Japan. But there was no standard for prerecorded video, and no movies were released for this player
Microsoft has since entered into talks with Sony regarding Blu-ray,[SUP]

Windows Vista has supported basic filesystem

The first mass-market Blu-ray Disc rewritable drive for the PC was the BWU-100A, released by
Sony on July 18, 2006

Since the Blu-ray Disc data layer is closer to the surface of the disc compared to the
DVD standard, it was at first more vulnerable to scratches.[SUP]

cartridges for protection, resembling
Professional Discs introduced by Sony in 2003
On January 1, 2010, Sony, in association with Panasonic, announced plans to increase the storage capacity on their Blu-ray Discs from 25GB to 33.4 GB via a technology called i-MLSE (
Maximum likelihood Sequence Estimation)
On July 20, 2010, the research team of Sony and Japanese Tohoku University announced the joint development of a blue-violet laser,[SUP]

با اینکه بسحتی میشه توی نت جزئیات مربوط بهroyalty ها رو بدست اورد ولی :
Sony is proposing a royalty fee of 1.5% of the net selling price or 3 US cents per BD-ROM disc(whichever is the greatest) and 1.5% of the net selling price or 6 US cents per BD-R/RE disc. It’s a confusing business
Instead of having to approach Blu-ray, DVD and CD holders individually and paying them separate royalties, the single licence should cut down the total cost of royalty payments by 40 percent, according to Sony.
The fees for the new licenses will be $9.50 for a Blu-ray player, and $14 for a Blu-ray recorder. Making Blu-ray Disc will cost 11 cents for read-only, 12 cents for recordable discs, and 15 cents for rewritable discs
تاپیک فرمت وار رو که جستجو کردم متوجه شدم که از اشکان(Wakashizuma) که فوق العاده در این زمینه حرفه ای به نظر میرسد همین سوال پرسیده شده بود:
سوال:حالا كه سوني موفق شد.سودي كه از blu-rayبه دست مياره چجورييه مثلا شركتايي كه ميخانbd-player بزنن ميان به سوني پول ميدن
يا سوني درصد ميگيره رو playerياbd-r
Wakashizuma: از royalty که از فروش دیسک به دست بیاد. به طور مثال سونی توی DVD زیاد patent و IP نداشت برای همین زیاد royalty گیرش نیومد و سهم زیادیش به توشیبا میرسید که patent های زیادی توی DVD داشت. همچنین patent های سونی توی سیدی هم سال 2008 تموم و expire شد (مدت هر patent بیست سال هست).
با موفقیت بلوری سونی میتونه سود عظیمی از royalty ها به دست بیاره. بعد از سونی هم فکر کنم پاناسونیک بیشترین patent رو توی بلوری داره. اینی که البته گفتم حدسه.
سال 2008 هم شایعه شده بود که سونی و فیلیپس روی هر بلوری پلیر 30 دلار میگره.
Sony Corp. and Royal Philips Electronics – demand $30 fee of every drive capable of reading Blu-ray
معمولا همچین اطلاعاتی به سخت جایی درز میکنه و جزئیات قراردادهای مالی مخفی میمونه.
موفق باشید.
