DVR Software

How DVR Software Works

In the wonders of the digital age, it was always inevitable that a digital video recorder (DVR) would evolve. Also known as a personal video recorder, DVR has largely relegated video cassette recorders (VCR) to the museums or at least to gather dust in the attic shelves. What makes the DVR completely different and so much better than its predecessor the VCR is that it capable of recording directly onto a hard disc, instead of on to a video or cassette. If desired the media recorder on the DVR's hard disc can be transferred to a DVD disc.

As well as being in the form of stand-along box units for television and film, DVR hardware can be added to a home computer and will perform the same functions. In order to operate the DVR hardware, certain DVR software programs have been developed. The role of the software is to allow any computer to recognize and operate DVR cards that have been installed.

In all cases, the operating system resides on the hard disk. As well as the software, the operator sets aside considerable space to store material that has been downloaded and recorded.

Also known as a video capture card, the DVR card determines the quality of the entire viewing and recording system. In the simplest of terms, the better the quality of the DVR card the higher the reception quality. And also the quality of any recordings made.

 What defines the quality level of a DVR card is the compression-decompression software (Codec) that it contains. Codec comes with the ability to capture as well to compress, and decompress video data. In today's market it is possible to purchase DVR software cards in the following qualities: Industrial quality, Economy quality, and Consumer quality versions.

Obviously price pays a fairly considerable factor in the quality of the software.

However many people, even those who are buying a DVR system for home use are prepared to invest the extra even for an industrial quality DVR card.

The truth is that buying a lower quality card is the worst form of false economy. Anyone who is prepared to spend the money to have a "top of the range" home cinema will for sure invest the extra few dollars for the finest quality reception.

This is because the higher the level of DVR card brings access to faster, more efficient processors for compressing and decompressing video data.

Just like computer processors, the more powerful cards are capable of processing date at considerably higher speeds. In addition the cards are capable of carrying out a variety of more advanced filtration functions.

For example, there is some very high quality DVR cards no being released to the market containing multiple processors. This function really speeds up date processing to a maximum. There are even some cards that can be set up to allow a single processor for each individual video channel.

The less powerful DVR card's that are slower will cause a syndrome known as "bottlenecking" which means that the images are not being processed quickly enough. This can cause a major shortfall in the viewing ability and can be very frustrating for the home cinema owner.

The good news is that DVR card's can be upgraded, so it is only a question of investing a few more dollars to reach a high quality reception level.

Advancements for the consumer are available all the time and many of the major satellite companies are now offering a DVR as part of their package. In comparison to the standards of DVR's available on the open market, the quality is not high. However they are generally inexpensive and serve as an entry to the world of digital video recording.
