When purchasing a DVD player, you need to pay attention to the following:
External content performance: in terms of basic functions. DVD players with Dolby AC-3 decoding, MP3 decoding, DTS digital output, optical fiber and coaxial output have become standard configurations recognized by the market and should be classified as mid-range; while the ones mentioned above do not have Dolby AC-3 The decoding machine is only at the DVD level in terms of image quality, and is not yet a standard DVD player. As consumers gradually improve their ability to appreciate audio, it will soon be eliminated from the market, because hundreds of them will It can be used as an entry-level product to meet the needs of some friends who have limited money to watch DVD programs.
The connotation of performance: reflected in the compatibility, stability and error correction of the product. Regarding this point, I think those who have experience with VCD players know better. When exciting programs cannot be played freely on the machine, the annoyance may make you more cautious when purchasing DVDs. Out of self-interest, some manufacturers rush to market before product solutions are mature to earn huge profits. Consumers should be particularly careful about this.
It is reflected in the ductility of the product: with stronger sound field layering, more nuanced sound details, richer and more digital flavor, high-fidelity HDCD support is only a new thing abroad, but there are Strong and responsible domestic manufacturers have made it the standard configuration of new DVDs. Relatively speaking, for the majority of audio and video enthusiasts, four-channel Dolby ProLogic surround sound (AC-3 or Dolby ProLogic). In the early days of the development of audio-visual technology, this method was popular all over the world as a de facto standard, and almost all multi-sound movies, LD and music products adopted this method. For this kind of output form, in the past, we often used an external power amplifier with this kind of decoding function to experience the cinema-like shocking effect. Some powerful brand DVD players already have this kind of decoder built-in, and the price remains basically unchanged. In addition, it is worth mentioning that some well-known manufacturers in the audio industry have also noticed this new change in the DVD player market and are working on developing a six-channel pure power amplifier without any decoding. This new product will help the majority of audio and video users rationally allocate resources and will not waste investment due to duplication of functions.
