What is "DVD Format Book" ?

For details on the DVD Format Books currently available, please see DVD Book Construction.
Q.4
What is "Optional Specifications"?
A.4
Optional Specifications define the standards which are an extension, yet at the same time, option, to the particular DVD Book. The scope of the technology in the Optional Specifications is covered by and dependent upon the technology disclosed in the DVD Book. Therefore, the Optional Specifications disclose the standards compatible with the DVD Book. Optional Specifications automatically follow the latest version of the DVD Book.

To differentiate the versions, "Revision" number, instead of "version" number, will be assigned to Optional Specifications. The revision-up of the Optional Specifications may be made independently from the DVD Book.
When the products adopt features described in the Optional Specifications, they shall be properly manufactured conforming to the Optional Specifications.
Q.5
I would like to apply for License for a copyright management system, such as CSS or CPRM/CPPM. What should I do?
A.5
DVD FLLC is not handing such Licenses. For CSS License, please visit DVDCCA's website. For CPRM/CPPM License, please visit 4C Entity's website.
Q.6
I have an older version of DVD Book. Can I replace this with the latest version?
A.6
If your DVD Book is applicable to the "Phoenix Plan", you may update your older version to the latest with this replacement service. For details, please see For Book subscribers.
Q.7
What is the difference between "Gbytes" and "GB"?
A.7
DVD Format Books specify the storage capacity by "Gbytes", not "GB." Since "Gbytes" and "GB" represent different values, DVD FLLC recommends that the Licensees use "Gbytes" as the unit on the packages of their products and on the related materials.

<Ref.>
1 Gbytes
= 109 bytes (1,000,000,000 bytes)
1 GB = 230 bytes (1,073,741,824 bytes)

4.7 billion bytes capacity of 12 cm diameter DVD disc is equivalent to 4.7 Gbytes, not to 4.7 GB.

License
Q.1
Who needs the DVD Format/Logo License?
A.1
The manufacturers who wish to manufacture following types of the format-compliant DVD products need to enter into the DVD Format/Logo License Agreement with DVD FLLC:
1) Replicators of pre-recorded DVD Discs / Manufacturers of writable DVD Discs
2) Manufacturers of DVD Players, Recorders, Drives, Decoders and PC Recording and Authoring Software.
3) Manufacturers of other DVD Products that utilize the information disclosed in the DVD Format Books. These include IC Chip makers and venders of authoring tools for professional use, etc. (It must be noted that the products under this category are not permitted to carry the DVD Logo, since there are no established methods of Verifying these items).
Q.2
Why do we need DVD-ROM Book and License to manufacture DVD-Video Players?
A.2
DVD-Video Disc is a disc that uses DVD-ROM Format, as a disc format to define the basic methods of storing information on the disc (therefore, it can be called as DVD-ROM Disc) and also uses DVD-Video Format as an application format for recording and playback of contents such as movies (it consists of DVD-ROM Format and DVD-Video Format). In order to properly play contents on the disc consisting of such 2 formats, the manufacture of DVD-Video Player needs DVD-ROM and DVD-Video Books and their licenses.
Q.3
Do we have to pay per-piece royalties?
A.3
We do not collect per-piece royalties or annual fees, in addition to the NDA/Book fee and License fee. There are no recurring fees during the period of present License unless you wish to purchase additional DVD Format Books or obtain additional Licenses.
Q.4
Does the DVD Format/Logo License Agreement include a DVD patent license?
A.4
The Agreement does not include any patent license.
Q.5
Does a PC manufacturer (Company A) need the DVD Format/Logo License? Can Company A affix the DVD Logo on its PC?
A.5
If Company A is manufacturing a PC by assembling the components including an outsourced DVD drive into the PC, Company A is NOT considered to be a DVD manufacturer. Therefore, it is not eligible to become a Licensee, and is not authorized to place the DVD Logo on the PC on its own.

However, if the outsourced DVD drive is manufactured by a Licensee and has the DVD Logo affixed by such Licensee, Company A may leave the DVD Logo on the final product; the PC. Or, if given instructions and approval of the licensed DVD drive manufacturer, Company A may affix the DVD Logo on the outer casing of the PC, to a particular location designated by the Licensee. Usually, the location to be designated would be on the outer bezel of the DVD drive. If it is difficult to affix the DVD Logo on the outer bezel, or in case there is no bezel, on the area of the outer casing as close to the bezel area as possible in order for the Logo not to lose its association with the DVD drive. Company A should turn to the Licensee for instruction and guidance on the appropriate location.

Naturally, it is the manufacturer of the DVD Products, in this case the drive, that needs to obtain the applicable DVD Format/Logo License(s) and to undergo applicable Verification. The PC manufacturer is recommended to inquire whether its supplier is (a) a Licensee and (b) has completed Verification.
Q.6
Can Company A affix the DVD Logo on the casing of the external DVD drive?
A.6
1) If Company A is a Licensee, YES, if the DVD drive is manufactured by Company A and has undergone Verification.
2) If Company A is NOT a Licensee, Company A may affix the DVD Logo, ONLY IF 1) the DVD drive that is enclosed in such external casing is manufactured by a Licensee and has undergone Verification, 2) no substantial changes were made to the function of the enclosed DVD drive, and 3) the DVD Logo is affixed under the instruction of the Licensee.
Q.7
Can Company A place a sticker that carries the DVD Logo onto the PC for promotional, advertising and/or marketing purposes?
A.7
As explained in A.5 above, Company A is not authorized to place the DVD Logo on the PC on its own. However, for the purpose of providing the functionality or the feature of the PC, Company A may display the DVD Logo if the following conditions are fulfilled:

1) The DVD Product (such as a DVD drive) that is incorporated into the PC is manufactured by a Licensee, who has undergone Verification for such DVD Product.
2) The DVD Logo is applied in a manner that permits easy removal after the useful life of the message, such as with stickers that strictly follow 4) below.
3) The Logo is placed under the instruction of the Licensee manufacturer of the incorporated DVD Product.
4) The sticker must contain both a) and b) below. The DVD Logo may not be singularly used on the stickers:

a) DVD Logo:
  The Logo to be used is the "Application Logo" that is appropriate for the DVD Product incorporated. It must be used in the form and manner specified in the DVD Logo Manual. It is essential that the Clear Zone is maintained.
b) Accompanying Information:
  The Logo must be accompanied by the message describing such function or the feature of the PC. For instance, "This PC contains DVD-ROM Drive."
