The DVD was originally developed by Sony, Panasonic, Toshiba, and Philips in 1995, which quickly became the format of choice for home video viewing, for it provided users better image &sound quality, a better data lifespan, and interactive features. In the early 2000s, Blu-ray was developed and the first consumer Blu-ray players hit the market in 2003. And Blu-ray gradually occupied the market and finally won the high definition format war, for it allowed the storage of high-definition and ultra-high definition video. What is more, Blu-ray has seen adoption by not just the home video industry, but also the video game industry. While many consumers might assume that Blu-ray is superior to the DVD format just because it’s new, but they may not know the big differences between Blu-ray and DVD. So if you just want to know more, you’ve come to the right spot. We will draw a comparison between DVD vs Blu ray quality.
DVD vs Blu ray
Blu ray vs DVD quality: Resolution
As we all know, image resolution is measured by the number of vertical lines times the number of horizontal lines of light in a picture. In fact, you can get 1920×1080 pixels on a Blu-ray—that’s 2,073,600 pixels while DVD delivers just 345,600 pixels in America, which means Blu-ray is almost exactly 6x the resolution of DVD.
DVD vs Blu ray capacity: Storage capacity
Each Blu-ray- Single layer Blu-ray discs store approximately 25 GB of data, while double layer Blu-ray discs can hold about 50 GB of data which is equal to about four and a half hours of high definition information or 26 hours in standard definition. Therefore, you can get a lot higher quality video and the supported video compression formats made for a better picture and more efficient use of space. And DVD- Single layer DVDs can only store about 4.7 GB of data, and double layer DVDs can store twice the amount of data at 8.7 GB.
DVD vs Blu ray: Audio quality
DVD audio, specifically as defined in the Red Book standard, consists of two channels (stereo) of 16-bit, 44.1 KHz linear-PCM audio. Blu-ray, by comparison, can support several audio formats, such as the Multi-channel LPCM, Dolby TrueHD, DTS-HD Master Audio, Dolby Digital Plus …The Blu-ray standard only requires LPCM, core DTS and basic Dolby Digital decoding, but most players these days implement TrueHD and DTS-HD MA as well. So, Blu-ray supports much higher quality audio than DVD.
DVD vs Blu ray: Player compatibility
Blu-ray discs cannot play in a standard DVD player, for the red laser used in DVD players is too large to read the tiny grooves in a Blu-ray disc. Currently, all Blu-ray players sold on the market are backwards compatible with standard DVDs. However, the DVD image displayed, while still decent, will not be high definition quality like a Blu-ray disc.
