LG BD370 - Blu-ray and MKV in one place?
Our first more breathtaking writing on the subject appeared almost a day exactly a year ago, when was placed on the table the LG BE06 BR Roaster. In this article, the brand and the topic are unchanged, but now we are approaching a little differently: this time we got a consumer electronics product from the manufacturer, which is definitely a pioneer of its kind.
Our article mentioned above Second page we can find a complete technological overview, so now we would just say a few words about Blu-ray. In the beginning, there was the CD, but it already looks back on such a long history, and we have dealt with it so many times, that we only mention the first silver disc. The next step is the DVD, which, in a very simplified way, "only" differs from the CD in that the disc has different physical parameters, and the pits (the elementary information units on the disc) are located "closer" to each other, which can be removed with a laser beam of a smaller wavelength onto the carrier. If we approach things from the latter point of view, then CD belongs to infrared lasers, DVD to red lasers, while HD DVD and Blu-ray belong to blue lasers.
If you’re already on the laser beam, take a look at the image below, which is a great illustration of the differences between the different formats:
It is clear that as we move forward in time, the diameter of the laser beam will become smaller and smaller, ensuring an ever-increasing data density (remember: from CD to BR, all discs have a diameter of 120mm). A factory BD-ROM is typically a dual-layer disc, meaning publishers can manage a total of 50 GB of capacity. That's just enough of the physical characteristics for us now, but what about the standard itself?
To put it very simply, Blu-ray has a higher resolution (1920 × 1080p) and bitrate compared to DVD, a higher color depth and up to 7.1 losslessly stored audio stream, as well as various - even interactive - extra features (for example: BD -Live). In other words, everything is in place to deceive a significantly better quality from the bluish format than it was anno on DVD. (We could have mentioned the different video encoding here, which, however, would not be entirely correct, since nowadays almost no MPEG-4-based publication was published in the beginning, almost exclusively with an MPEG-2-based process.) Of course, a properly prepared source material, post - production and garnish - display, amplifier, speakers, etc. - must. Perhaps it can also be seen from these that when a certain level of quality is reached, the quality of the player is much less decisive than in the case of DVD. Strictly speaking, it is enough for a BR player to know the specifications, the others are mostly decided on the display side, for example - that is, the manufacturers are in a slightly easier position in this respect, and judging the picture quality promises to be a much more interesting task.
