Comparison of High Definition Optical Disc Formats

Comparison Of High Definition Optical Disc Formats

This article compares the technical specifications of multiple high definition formats, including HD DVD and Blu-ray Disc; two mutually incompatible, high definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard. The two formats remained in a format war until February 19, 2008 when Toshiba, HD DVD's creator, announced plans to cease development, manufacturing and marketing of HD DVD players and recorders.

Other high-definition optical disc formats were attempted, including the multi-layered red-laser Versatile Multilayer Disc and a Chinese made format called EVD. Both appear to have been abandonedby their respective developers.

    But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.
    Ralph Waldo Emerson (1803–1882)

    But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.
    Ralph Waldo Emerson (1803–1882)

    If you’re anxious for to shine in the high esthetic line as a man
    of culture rare,
    You must get up all the germs of the transcendental terms, and plant
    them everywhere.
    You must lie upon the daisies and discourse in novel phrases of your
    complicated state of mind,
    The meaning doesn’t matter if it’s only idle chatter of a
    transcendental kind.
    Sir William Schwenck Gilbert (1836–1911)

    It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.
    François, Duc De La Rochefoucauld (1613–1680)

    The convent, which belongs to the West as it does to the East, to antiquity as it does to the present time, to Buddhism and Muhammadanism as it does to Christianity, is one of the optical devices whereby man gains a glimpse of infinity.
    Victor Hugo (1802–1885)

    “What,” it will be questioned, “When the sun rises, do you not see a round disc of fire somewhat like a guinea?” O no, no, I see an innumerable company of the heavenly host crying “Holy, Holy, Holy is the Lord God Almighty.”
    William Blake (1757–1827)
