Blu-ray disk format utilizes two video compression codecs for recording full length HD movie. One recording format is VC-1. This recording codec was co-developed by Microsoft. VC-1 is the variation of the Microsoft’s Windows media codec. Higher compression is offered by VC-1 codec and the signal loss during the process of encoding/decoding has been minimized. The other recording codec used by Bluray disk format is advanced video coding (AVC). It is an enhanced form of MPEG-4. The DVD disk format uses the MPEG-2 compression codec. MPEG-4 codec used by Blu-ray disc technology is more efficient than its predecessor MPEG-2. Bluray disk technology offers superior and exceptional quality of audio/video at lower bit-rates that the DVD disc format. The HD quality offered by Blu-ray media disks exceeds the users’ expectations. Both these recording codecs offer more flexibility to the studios for recording their Bluray media disks. When the pre-existing DVD released bonus features are ported to the Blu-ray disk format, then they are recorded in the MPEG-2 codec. The Bluray disk players are very useful as they can also play the DVD media disks thus providing additional benefit to the users.
Bluray disk players also perform the up-gradation of the 480p DVD standard to the quasi high definition levels and then up to resolution of 1080p. That is how a Blu-ray player enhances the resolution and quality of DVD. Blu-ray disk format supports the latest HD audio codecs. The combination of advanced A/V receivers, decoding power and massive storage capacity of Bluray technology ensure such high quality. The other two competing codecs Dolby TrueHD and DTS-HD Master Audio have the capability to reproduce 7.1 discrete audio channels with increased dynamic range and accuracy ever before achieved in home. In order to shrink the storage requirements and bandwidth, these codes use compression. As a result of this compression, the soundtracks produced are the original PDM master tapes’ bit perfect copies.

Interactivity has been improved in the Blu-ray disk technology. BD-Live is also supported by the BD-ROM Profile 2.0. Its features can be updated through the internet. The Profile 1.1 players require WiFi connection or Ethernet port for fast speed internet connectivity. That is why most of the profile 1.1 Bluray disk players will not support the profile 2.0. The players need to temporarily store at least 1-GB of varying data amount. Use of SD memory card of USB flash drive can do the trick. The latest Bluray disk players fully support BD-ROM 2.0 Profile. These Blu-ray players also have network ports that help the users in enabling new features and fixing bugs. Java software is an essential component of the Blu-ray specification that assists in interactivity and elaborates the popup disk menus. On the other hand in DVD format, the animated menus are pre-rendered. The top games of new generation also benefit from the highly reliable BD-Java technology. The outer layer of the high capacity Blu-ray media disk is more durable and harder that protects the surface from scratches and dust particles thus resulting in a more efficient and reliable media disk technology.
Author Resource:-Bluray DVD disk is also known as BD. Blu-ray disk format was developed in order to enable rewriting, recording, and playback of high-definition video HDV. Bluray recordable DVD disc can hold large amounts of data.
