DVD

DVD stands for Digital Versatile/Video Disc,

DVDR stands for DVD Recordable and

DVDRW for DVD ReWriteable.

 

There are three competing DVD Recording standards, DVD-R/DVD-RW and DVD+R/DVD+RW have pretty similiar features and are compatible with many standalone DVD Players and most DVD-ROMs while DVD-RAM has less DVD Player and DVD-ROM compatibility but better recording features.

 

DVD-R was the first DVD recording format released that was compatible with standalone DVD Players.

DVD-R is a non-rewriteable format and it is compatible with about 93% of all DVD Players and most DVD-ROMs.

DVD-RW is a rewriteable format and it is compatible with about 80% of all DVD Players and most DVD-ROMs.

DVD-R and DVD-RW supports single side 4.37 computer GB DVDs(called DVD-5) and double sided 8.75 computer GB DVDs(called DVD-10).

These formats are supported by DVDForum.

 

DVD+R is a non-rewritable format and it is compatible with about 89% of all DVD Players and most DVD-ROMs.

DVD+RW is a rewritable format and is compatible with about 79% of all DVD Players and most DVD-ROMs.

DVD+R and DVD+RW supports single side 4.37 computer GB DVDs(called DVD-5) and double side 8.75 computer GB DVDs(called DVD-10).

These formats are supported by the DVD+RW Alliance.

 

DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 7.95 computer GB (called DVD-9) and dual layered double sides 15.9 computer GB (called dvd-18).

 

DVD-R DL or called DVD-R9 is a Dual Layer writeable DVD-R. The dual layered discs can hold 7.95 computer GB (called DVD-9) and dual layered double sides 15.9 computer GB (called dvd-18).

 

DVD-RAM has the best recording features but it is not compatible with most DVD-ROM drives and DVD-Video players. Think more of it as a removable hard disk. DVD-RAM is usually used in some DVD Recorders.

This format is supported by DVDForum.

 

DVD Sizes

The DVD sizes can be a bit confusing. There are basicly 4 different DVD Sizes,

 

DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.

 

DVD-10, holds around 9 400 000 000 bytes and that is 8.75 computer GB. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Double Sided Single Layered.

 

DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media.

 

DVD-18, holds around 17 080 000 000 bytes and that is 15.9 computer GB. DVD+R supports this format. Also called Double Sided Dual Layered.

 

DVD+R/DVD+RW/DVD+R DL and DVD-R/DVD-RW exact sizes

DVD-R/DVD-RW = 4 706 074 624 bytes ( 4488 MB )

DVD+R/DVD+RW = 4 700 372 992 bytes ( 4482 MB )

DVD+R DL = 8 547 993 600 bytes ( 8152 MB )

 

DVD Write and read speeds

Single Layer(4.7GB) write speeds

1x (CLV) = about 58 minutes

2x (CLV) = about 29 minutes

2.4x (CLV) = about 24 minutes

4x (CLV) = about 14.5 minutes

6x (CLV/ZCLV) = about 10-12 minutes

8x (PCAV/ZCLV) = about 8-10 minutes

12x (PCAV/ZCLV) = about 6.5-7.5 minutes

16x (CAV/ZCLV) = about 6-7 minutes

 

Dual/Double Layer(8.5GB) write speeds

1x CLV = about 105 minutes

2.4x CLV = about 44 minutes

4x CLV = about 27 minutes

 

Single Layer (4.7GB) read speeds

1x read speed is 1.321MB/s = ~56 minutes

6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes

8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes

12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes

16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes

Es gan rakstu tikai DVD-R matricās. Kaut kur lasīju, ka iekārtu, kas atbalsta DVD-R ir vairāk nekā tādu, kas atbalsta DVD+R, līdz ar to rakstot DVD-R ir lielāka garantija, ka to matricu varēs nolasīt jebkurā DVD lasītājā, it sevišķi tas attiecas uz stacionārajiem DVD lasītājiem kā mājas kinozālēm utml.

DVD-R:

Benefits: Better DVD playback compatiblity within home DVD players.

Drawbacks: Older technology and less money behind the format means that they come out with faster media and burner technology slower. You will frequently see DVD burners that will support (for instance) 16X DVD+R and only 8X DVD-R.



DVD+R:

Benefits: Faster speeds, more inovations like Double Layer discs (8.5 GB)

Drawbacks: Will not play is some home DVD players. If you know your home DVD player will play DVD+Rs then there is no reason to not use them.

Principā starpība nekāda! Ja neesi bagais sīkumu meklētājs. Viens ražotājs izdomāja "+" un cits ražotājs "-" (ja nemaldis, tad viens no tiem ražotājiem bija Sony, otru nepieminu)

Lemoninsh, no kādas sasodītas alas tu izlīdi, ka bija tik akūta vajadzība citēt 7 gadus vecu postu pastāstot visiem zināmu patiesību? :wtf:

 

Klapēšu ciet, jo par DVD vairs neko jaunu nevar atklāt un tehnoloģija sevi izsmēlusi nākot vietā Blueray.
