All DVD-Video discs, both for PAL and NTSC regions, must include Dolby Digital mono, stereo or multi-channel audio as a minimum requirement.
Regardless if there is a logo on release packaging - Dolby audio is present. Should Dolby then be listed on ALL releases as a company?
ALSO: Why would a "series" be considered a COMPANY?
Both companies do not appear on every DVD release ever released.
Even those that to carry a dolby logo or Dolby audio dont have these printed all the time.
So IMO if these licensing-companies appear in the copyright/licensing/distribution section of a release they should be added.
E.g. the name namechange that was done at about 2011 wouldnt have been documented if they weren't added.
If they appear as licensing-company ("Dolby Laboratories Licensing Corporation" or "Dolby Laboratories") they should be added.
per DVD-Video specs - All DVD-Video discs, both for PAL and NTSC regions, must include Dolby Digital mono, stereo or multi-channel audio as a minimum requirement.
Not referring to a logo on packaging.
Dolby audio (AC-3) is not the only audio format that can be used on a DVD-Video disc.
The formats are:
- MPEG-1 Audio Layer II (MP2)
- Dolby Digital (AC-3)
One type of audio is required, and it doesn't have to be Dolby Digital (AC-3), although AC-3 is the most popular.
This document created and hosted on the Dolby website answers this question.
Question 9. Do all DVD-Video discs have Dolby Digital soundtracks?
Discs distributed in countries that use the NTSC broadcast TV standard (such as the U.S.) must provide at least one soundtrack in either of two formats: Dolby Digital or PCM (the format used on CDs). In countries using the PAL TV standard (including much of Europe), the discs must include at least one soundtrack in any one of three formats: Dolby Digital, PCM, or MPEG. As a result of these requirements and the options they permit, not all discs have Dolby Digital soundtracks.
I authored a lot of DVDs back in the day and some only with an uncompressed stereo PCM track.
So, unless stated on the DVD packaging, you'd have to check your DVD-specs via software or stream details on a hardware player.
Why would a "series" be considered a company?
I suspect this is largely due to the fact that series is in the 'companies' section in Discogs. Regardless of that, I place them in the companies section in Filmogs because 'Series' are part of a company's branding, with all that entails.
When you put the series as a company, it allows you to view all the different releases associated with that branding. Same layout is used on artists and companies. Sure you could put it as a "series", but it still gets the job done regardless.
