Benefits of digital television and TV tuners over analogue

It is a well known fact that digital television has many advantages, including support of widescreen image, quality sound, compatible with standard Dolby Digital 5.1, and support for picture with higher resolution and detail, much higher than that of standard TV or DVD movies. The other big advantage is called multi channeling and it is the possibility of choosing specific video content in different channels or services of the type “video on demand”. Another important argument in favor of digital television is the fact that the signal is not susceptible to interference. Since the broadcasts are in digital format MPEG-2 (same as DVD content, although with a slightly different quality), the picture is always clear and clean. Moreover, the digital signal is distributed in the same frequency spectrum as analog FM, so it does not require any upgrade of the antennas.

TV signal is taken by the antenna passes through the tuner and then through the decoder. Finally, the card sends the received information to the MPEG-2 decoder. Usually even the most simple and cheap tuners for PC come with some software tools for recording and watching TV, so there is no need to make any further investments.
