Best BluRay Disc

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.
