HD-DVD vs. BR

Advanced technology always has a way to win its rivals, to establish and maintain the success that snatched from its competitors for its existence.   The paper will do: rubric #1, 2, 3, and give a brief conclusion.

Rubric #1

The two organizations are Toshiba from MS and Sony (Toshiba on HD-DVD side while Sony on Blu Ray side). A follow-up article on the origins of the format war presented Microsoft’s efforts to push its Windows Media and WinCE as essential, proprietary aspects of both the new HD disc formats. While Microsoft successfully wrote Windows Media (aka VC-1) into the specification of both Toshiba’s Advanced Optical Disc (AOD) and Sony’s Blu-Ray, the Blu-Ray consortium members later selected Java-based technology from Sun as its interactive menu layer rather than Microsoft’s WinCE/HDi. Years earlier in 2003, the DVD Forum had chosen Toshiba’s AOD format as the successor to DVD because the company promised it would be finished sooner than Sony’s Blu-Ray; the Forum subsequently renamed Toshiba’s format HD-DVD to associate it with DVD, while Sony continued work on Blu-Ray (Dilger, 2008).

Rubric #2

Yes. The paper agreed and addressed its rationale as follows. Among many reasons for the difference between BR and HD-DVDs is capacity. Both are used as storage for audio, video, and data. For both, the same size 12cm optical disc we're all used to. HD-DVDs can store around 4.7GB worth of data on a single side (8.5 for a dual layer DVD). BR may store ten times the HD-DVD. Without getting too technical, the reason for the increased storage has to do with the type of lasers used. DVDs (and CDs) use a red laser to read and write data to and from a disc. Blu-ray and HD DVD both use a blue laser. HD DVDs can store up to 15GB on a single layer while Blu-ray can hold 25GB on one layer. Even more can be packed into Blu-ray/HD DVDs if they use more than one layer or one side of the disc (Ramsay, 2008). According to Huereca (2004), the author discussed the benefits and drawbacks of the two formats as illustrated below in table 1.

Table 1 Benefits and Drawbacks of HD-DVD and BR

Features	Benefits of BR	Drawbacks of HD-DVD
1.     Resolution	1920x1080p	720x480p
2.     Capacity	50GB	4.7GB
3.     Backed by	13 large corporations including Dell and Sony	Only three corporations Microsoft, Toshiba, and NEC

 

Rubric #3

According to Diffen (n.d), the author examined BR and HD-DVD processes and compared and contrasted as presented in table 2 below.

	BR	HD-DVD	BR	HD-DVD
1.     Video play back time	-	-	8.5 hours	5.1 hours
2.     Content Protection	AACS-128bit	AACS-128bit	-	-
