DTS, AAC, MP3, WMA codec

In modern conditions, in the digital age, sound transmission occurs digitally. The sound file can be transferred in an uncompressed state, but in this case the volume of the digital file will be very large. To reduce the amount of information transmitted, various codecs were invented. The original audio file is compressed using the developed algorithm. A device that plays audio decodes a compressed file and plays sound. The procedure for encoding and decoding an audio file is prescribed in the algorithms developed by various companies. The most common codecs are DTS, ACC, MP3, WMA. These codecs compete with each other using slightly different coding algorithms, so the codec has certain disadvantages. The popularity of codecs plays a large role in whether device manufacturers support the corresponding codecs.

What the viewer can experience discomfort

When watching video on an HD television quality and with the support of the DTS sound track, if your TV does not support this format, you will not hear the sound on the TV. But to tell the truth as a rule can be maintained and other audio standard, there may be several audio tracks, is another question if the TV supports their choice.

Just need to pay attention to the audio codec. But if we take the example Philips PFL4208T it does not support Dolby Digital and DTS.
