Blu-ray and HD-DVD

There have been various inventions in the field of storage media and video formatting. All these developments have brought about changes in the way users started using different Medias including movies and television. There came different methods of storage even in the filed of optical storage system itself. There came the blu ray disc storage system as well as the HD DVD system of storage.

Blu ray disc is a storage media format using the optical storage techniques. This is highly used in high definition storage for data and video with the dimensions similar to that of a standard DVD or CD. HDTV is high definition television. They can offer better resolution as compared to the standard traditional systems. They use lower bandwidth. This can give more clarity to the picture and sound as compared to normal television.

There are several differences between the storage medium offered by blu ray disc and a HDTV. They have a similar working pattern despite the differences. The differences can cause a great change in the specifications. Thus the storage capacity for a blu ray disc is higher than that allowed in a HD-DVD. While the interactivity supported in a blu ray disc is BD-J, which in a HD-DVD uses an HDi format.

The standard data transfer rate in a blu ray disc is 36 Mbps as compared to a 36.55 Mbps in a HD-DVD. Yet the video resolution appears to be similar in both with a 1080p resolution for video. There is a hard coating in blu ray disc which will be unavailable in the HD format used in HD-DVD.

There has been a tough competition prevailing in the market between the techniques used in HD-DVD and blu ray discs. There then introduced hybrid discs which can support both the techniques available in blu ray disc and HD-DVD. The high storage capacity, content and support from the leading electronics manufactures have helped blu ray in a wide scale to excel HD-DVD in the market to an extent though the other also had several advantages over blu ray disc.
