Today, when everyone has completely forgotten about cassette video players, and moviegoers, music lovers and karaoke lovers have only increased, the choice of a good CD player is an important issue for many people. A CD player, aka a DVD player, is a reader laser discs with the output of the image and sound to one or more external devices. Even 15 years ago, any such disc player began to be called an SD player. The name is still used. Now we’ll take a detailed look at how to choose a reliable DVD player for a pleasant pastime.
The motto of this brand has always been an innovation, and it was not for nothing that it called the launch of the first plasma TV and other important products in the technological world. Their design is characterized by a certain level of sobriety, combined with a very bright strength for the most demanding users.
If you plan to find the best, you do not have to go very far, since any of the options offered by this brand has been produced with a good level of optimization and, most importantly, taking into account your needs, what users appreciate to a large extent.
How to choose a good DVD player
Any choice, including the choice of a good CD-player, is associated with a clear awareness of their capabilities and needs. What is important to you? Exceptional image and sound quality, the ability to play videos of any format, design, size, reliability, ease of use and settings. But if you don’t know where to start, start from the TV. There are many options where to start thinking about your choice. The starting point may be the manufacturer or functionality, it may be personal preference. But if you recall where any DVD player pulls its wires, the answer becomes obvious. Most buyers already have a TV and you need to start the choice with its capabilities. If you are a happy owner of a TV with a diagonal of more than 30 inches, then you should responsibly approach the choice of the future CD-player. Those imperfections of the image that the owner of the small screen will not notice, will be clearly visible to you, and can significantly spoil your mood. However, if the diagonal of the screen of your TV does not exceed 25 inches, “budget” models of any worthy brand, for example Pioneer and LG, are quite suitable for you. They are available starting from 2000 to 5000 rubles. We should also mention the sound. You can buy the best DVD player and put the sound on the TV, but then you will pay for something that you will not hear. Modern players allow you to transmit sound, divided by channels, creating surround sound. Even an ultra-modern TV is not capable of this.
These products were some of the most recommended, but now they are no longer available.
But let us pass directly to the strengths and weaknesses of this apparatus. Users comment that connecting to the Internet is quick and easy. Wireless connection. Ideal for connecting to a home theater system. Users are satisfied with the versatility of their work. If you want to see your favorite series with excellent quality or just want to see international news, just set up your channel.
But let's look one by one what are the advantages of this model. Formats One of the advantages is that this player reproduces the most famous and most used formats worldwide. If you still cannot find what you are looking for, we invite you to find out this product, which is a very good value for money. Let's look at some of its main features in the following list of pros and cons.
Key Features of DVD Players
It doesn’t matter if you are looking for the best CD player or an inexpensive but good one, it’s always a good idea to go through all the characteristics of a CD player first. They vary in:
- Characteristics of DACs: Quality directly depends on them. Important parameters are: sampling rate - BH and bit depth - bit rate. How fast the DVD player’s chip digitizes the signal and converts it to analog depends on the black hole. Bit depth is responsible for signal quality. The higher the BH and bit depth, the better sound or video. The following DAC parameters are considered good: video - 12-bit, the sampling frequency is 108 MHz; audio - 24 bit, sampling frequency 192 kHz.
- Supported image enhancement technologies. Each manufacturer of a CD player boasts its own functions, but often they just have a different name and implementation. Particularly picky moviegoers, as well as owners of huge modern TVs, should pay attention to this aspect. In the specifications of each device, these technologies are spelled out, but trying to clarify this point with the seller is useless, it is better to search for information on the Internet yourself.
- Supported formats: almost all devices available on the market support audio formats: AAC, Audio CD, CD Text, MP3, WMA, DVD-Audio, Super Audio CD; video formats: MPEG4, DivX, MPEG1 and MPEG2; image formats: JPEG and PNG. Support for such standards is a kind of standard, however, in the specifications when buying a DVD player you should still pay attention to them, if you don’t find what you need there.
Video outputs
Materials: it is made of a very durable aluminum alloy that protects its internal parts, so that you can carry it from one place to another without fear, because it tolerates shock and is not easily scratched. This material is also lightweight, making the device less than 500 grams in weight.
The new standard was called the Green Book. Some units recognize them better than others. For getting additional information check: " File system". The standard is called the White Paper. This is a limitation of the format itself. This type is one of those that have greater recognition in the most different devices.
The connectors of the DVD-player are divided into two types: audio and video. Each of them is divided into two types: digital and analog. Analog video connectors come in four flavors:
- Video 1RCA (composite) - analog composite input or output for direct connection to a TV. It is made in the form of one wire and one connector. Weak in quality. The components of brightness and color are mixed in it (and therefore composite). Rarely seen on enclosures of CD players.
- S-Video (Separate Video) - analog component (luminance and color components are separated) input / output. Direct connection to an external visualization device (TV, projector). It has one wire and one connector. You can find on the case of almost any DVD-player.
- SCART or Y / Pb / Pr - analog component input / output of audio and video signal for direct connection to the visualization device. It is made in the form of a single wire with a flat and wide connector.
- Video 3RCA or Y / Cb / Cr– analog component input or output. Direct connection to a visualization device. It has the cleanest and clearest signal of all analog. It can be made in the form of a cable with three wires and three connectors.
"Open" media means that you can enter data in stages, for example, on floppy disk. Purchasing goods in other countries is becoming more common. Therefore, you cannot play recorded discs for one region on a device destined for another. When you use them for the first time automatically, it will be programmed to the area of \u200b\u200bthe first disc inserted.
There are several ways to change this auto-tuning, but be careful because the number of modifications is limited. This was the way copyright studios for films, shows, and artists found that they had more control over their products. In addition, there is also the problem of piracy. With these locks, it becomes harder to make copies - theoretically.
You can not ignore the digital connectors. On a DVD player, they are usually represented by DVI and HDMI interfaces. These are two relatively young types of digital connections that can only be connected to compatible equipment equipped with the appropriate connection. The connection speed through such connectors is very high. They are designed to provide interaction with computer equipment, and therefore have full compatibility with it. The HDMI interface also supports anti-piracy technology. Not a single high-quality DVD player can do without this standard now.
See the table below to see which countries are part of each region. There are devices and drives programmed for the zero area. It is very rare to find such a configuration, but it exists. To start unlocking a drive, you must access the device properties. In the search field, enter “Device Manager” and press the “Enter” key. To access the settings, select the device, right-click and select “Properties”.
And even digital formats!
Stay with us in the “Other Changes” field to find out how many changes you can make. To change the disk area, select the desired country from the list that appears and click the "OK" button.
Single player or recorder
If you choose a reader-recorder, there are two main criteria to consider.But what about audio?
Now remember that we talked about connecting audio. You should not output it from a DVD-player to the TV, due to the weakness of the speaker system of the latter. Specially for DVD, technologies have been developed - Dolby Digital and Digital Theater, which, with a good speaker system, realize surround sound. So, the sound in the DVD is divided into 6 channels - they correspond to 6 analog output cables, and 6 speakers to which the cables lead. These are five speakers: 2 front (right and left), 2 rear (right and left), center and subwoofer. A subwoofer is needed to reproduce the lowest frequencies, the rest are distributed in columns. The subwoofer is as if separated from everyone else. Therefore, the systems are called six-channel and are denoted as 5.1. Now, even a budget DVD player supports this technology, and has 6 holes for RCA cables on its back for each corresponding speaker. But the best sound quality is obtained by digitally outputting sound to an amplifier. Of course, both the audio system and the CD player must have the necessary sockets for this.
In this case, consider the proposed capacity; if not, you will have to equip external hard disk. Advantage: you can choose the capacity and, possibly, change the disk, if necessary. Most of them have a built-in hDD. . One indicator: on a 500 GB disc, you can record up to 120 hours of high definition video and 240 hours of standard definition.
Dual tuner: record two channels simultaneously
Want to record your series while watching a movie on another channel? Would you like to be able to record two broadcasts simultaneously? It immerses you in the scene with the impression of being in the center of the action. To reproduce these effects, sounds are initially recorded on different tracks and then played back on different channels.
If you broke chinese player DVD - do not rush to carry it in the trash, if you are not married. If you are married, then, on the contrary, hurry up to avoid long philosophical conversations on the topics “what are the necessary things” and “lie down a bit - how much is this?”.
The Chinese player is a source of various nishtyakov. For example, a ready-made IR receiver (and if you managed to not sow the remote control from the player, then a transmitter) to build remote control systems of startling meaninglessness:
The impression of being in the center of action. The same principle exists for your home theater system. And you need an amplifier or player with multi-channel decoders to decode these audio files and broadcast them on each of the speakers in your home theater. Thus, the immersion effect will be reproduced.
And for each family, different formats with more or fewer channels. Speaking of multi-channel format 1, this means that sound compressed in this format uses six channels. In home theater 1, this means sound diffusion across five speakers and a subwoofer.
Yes, this black little thing with three legs. With pleasure he eats parcels from any remote control, giving out a luxurious TTL / CMOS compatible pulse at the output. Inside, by the way, the black little thing contains a rather complicated circuit, including AGC and a bandpass filter.
Or, for example, here’s such a breathtaking vacuum luminescent display, which just asks to be built somewhere in an electro-punk handicraft in the style of the 80s of the XX century:
Look at the reader information sheets that they integrate. On the menu: four times as many details and the best image quality at the moment. Drives have, depending on the model, more or less related functions. Depending on the models and brands, this will allow you to access more or less services.
And other practical connections
In more detail about their information sheet, the services offered by models interesting you. This standard allows you to create a wireless home network with all compatible devices. Or format? In this case, the discs you recorded will only play on a device with the correct decoder.
With such displays, everything is fine, except that to control them you need to fence the garden from a pack of high-voltage transistors of non-obvious polarity, and for power they need something about 24-27 volts. Well, the second, suppose, you can somehow make it using PWM and IRF630 with a throttle ... and the first does not present a problem if you look at the back of the board:
On a material level, you need a recorder, a disc, and blank media. You can find internal or external recorders. If the latter, this is not always the case. Soon they will become ubiquitous. A cache is a buffer zone in which data is stored until it is written. The more you want to burn at high speed, the higher should be the cache. The minimum cache is 2 MB. You can throw it away, it is screwed. Don't worry too much about this last point: all the latest recorders are equipped with one of these famous processes.
If you want to burn out on the fly - what we recommend - you need a reader. If your drive is outdated and your recorder is very new, make sure you have speed compatibility before making a backup on the fly. Once engraved, they are only picky. A priori, these latter drives may seem more flexible. In addition, the quality of the engraving is less effective on recordable media.
The modest microcircuit PT6312 is the controller for such candy displays. Inside itself contains everything you need, and even more than that:
- controlled by SPI
- supports 6x4 button matrix
- Able to do 8-step brightness control
- has 4 outputs for connecting LEDs (up to 20mA per channel)
- has 4 general purpose inputs
- It is functionally compatible with μpD16312 (FIG knows what it is, wrote off from the datasheet)
- Placed in a convenient 44-pin LQFP case, quite suitable for LUT
Purchased in boxes of 100, they cost very little, and no one regrets throwing them from time to time. These chemical compounds guarantee, in fact, a theoretical record life of about 100 years. Finally, if the reflection speed is indicated, be aware that the higher this indicator, the better the reading of your disk.
This allows, among other things, to install the distribution on low-performance computers. And yes, it does not require a lot of resources! Then, and this applies to everyone, you must configure the download. 
From one computer to another, this screen may be slightly different.
A typical connection scheme does not look completely scary even for a graduate of an engineering and economic school:
The difficulty with all these treasures is exactly the same - to come up with what to adapt them to. Maybe it was really easier to throw right away.
