The comparison between Blu Ray and HD DVD

  • The maximum resolutions supported via HDMI are 720p and 1080i HDTV in HD-DVD format
  • Blu-ray has a resolution of 720p, 1080i, and 1080p in HDTV.
  • Both are superior to EDTV 480p offered by the traditional DVD format.
  • Both the new technologies have equivalent maximum image-constrained native resolutions supported via component video, which is EDTV+ 960x540.

 

Blu-ray has more advantages with regard to the disc capacity:

Prototype

 

 

45GB (triple layer)

 

100GB (quad layer)

There is not much difference in the video capacity per dual layer disc of both the formats.

  • An HD-DVD has an SD of approximately of 24 hours and an HD of approximately 8 hours. The SD of Blu-ray is one hour less and the HD is one hour more than its competitor.
