So Do You Want to Make Blu-Ray Discs? OTO218_p16_19_Tech_Bluray 15/1/09 15:55 Page 16 technology The Blu-ray Disc was announced in February 2002. In 2005 the Blu-ray Disc Association (BDA) was formed and is now a voluntary membership group open to any organisation “with an interest in creating, upholding and/or promoting the BD formats”.The aim of the BDA is to develop Blu-ray Disc specifications; ensure BD products are manufactured by licensees; promote the wide adoption of BD formats and provide useful information to those interested in supporting BD formats. Blu-ray Disc formats Recordable versions of Blu-ray Discs also exist for use as a backup medium for computer data, as well as other applications. There is therefore a range of different formats based on Blu-ray, just as there are with DVD. G BD-ROM: a read-only disc format that would normally contain movies in HD content. G BD-R: a recordable format for archiving large amounts of data or video. G BD-RE: a rewritable disc format for recording video or data. All BD formats can be made in single-layer (25GB) and dual-layer (50GB) versions. Blu-ray Disc characteristics The developers of the Blu-ray Disc claim that it has the following characteristics: G Broadest industry support from manufacturers and So do you want to content providers. G Lifespan of at least 10 to 15 years due to its high storage capacity. G The strongest, renewable content protection, which includes strict licensing procedures. make Blu-ray Discs? G Cost of manufacture should be within 10% of the cost of DVD manufacture. G Highest capacity, for full-length movies in the There are a number of areas of expertise required to make highest quality HD video on a single disc. G Use of a hard coating, which offers stronger Blu-ray Discs, as Graham Sharpless explains resistance to scratches and fingerprints. IT HAS BEEN 12 YEARS since DVD was What is Blu-ray? Blu-ray versus DVD launched in Japan and 26 years since CD The Blu-ray Disc was developed to succeed DVD, Some of the key differences between Blu-ray and DVD appeared. The much more recent Blu-ray which was seen to be threatened by the launch of are listed in the table below: Disc (BD) represents the latest – possibly the last high-definition television (HDTV) services, – generation of optical disc format.

In BD manufacturing process the early years, DVD BD requires both mastering and replication processes, replicators often had but these are very different from the processes problems maintaining the involved in DVD replication. The smaller pits, reduced tight tolerances, cover layer and tighter tolerances present significant particularly during the challenges for the disc replicator starting out lifetime of the discs. manufacturing these discs. Blu-ray Discs, as the name suggests, use a BD mastering 405nm blue-violet laser to As with DVD mastering, BD mastering can be divided read the data and an into data formatting, laser beam recording and increased numerical stamper production.

But these an almost totally new approach is needed to meet the changes were regarded as critical requirements of BD – especially for the first two BDAV insufficient to achieve the required capacity without of these processes. BDAV is a read-only disc format for HD movies and is manufacturing tolerances being too tight.Therefore the The BD formatter/encoder is responsible for the the BD equivalent of DVD-Video.

  • Counting the Cost of Blu-Ray Licensing a Number of Issues Need to Be Addressed If Blu-Ray Is to Fulfil Its Potential
    OTO219_p16_21_BD_Licensing 6/4/09 13:51 Page 16 technology unwieldy or fail to fully take into account the BD production process. Finally, there is the cost, with cumulative licensing fees accounting for a substantial proportion of a BD disc’s manufacturing cost. BEFORE A CONTENT HOLDER CAN PUT CONTENT onto a BD disc and get it replicated, the holder needs to be licensed by the BDA licence entity.The BDA’s licensing activities include distributing the BD format books, logo guide and data, and issuing a compliance certification after a BD disc has undergone a stiff verification and testing process. There are several elements to the BD licensing scheme. Content holders, distributors and providers wanting to put content onto BD must take out a Content Participant Agreement, which costs $3,000 a year and runs for five years. There’s also a ‘light’ version that costs $500 a year and also runs for five years. There is no fee for the use of a Logo Licence Agreement, and there is an optional BD-Live Logo and Online Certificate Issuance Agreement, which incurs no charge, although there is a fee of $1,000 per private key. There are other BD licensing obligations. Disc replicators need to take out a BD-ROM mark interim agreement with Sony, Philips or Panasonic, while content providers must take out an AACS licence (see table, page 18). There’s also the option of taking out a BD+ licence for enhanced copy protection available from BD+ Technologies. Eric Carson, business unit manager, media manufacturing solutions, DCA, says:“The ROM mark is a nightmare – it’s the biggest pain point.
