Best Answer

The time it took to change analog television signals to all digital took about 25 years. It started around 1986 and many television stations had converted over to digital signal by the year 2010. Persons who owned analog televisions had to either buy a new digital television or use a converter box to get a clear signal.

What tv system is in Poland?

Analog TV is 625 line PAL, like in most of western Europe. Prior to 1995 polish analogue tv was broadcasted in SECAM D/K. Digital TV varies around DVB. For satellite platforms: Canal Plus owned Cyfra+, and Polsat owned Polsat Cyfrowy it's MPEG2 DVB, for TVN owned 'n' it's MPEG4/AVC DVB. For cable it's DVB-C. There's no conversion to terrestrial digital TV, and it has not as for this moment been decided if it's going to be MPEG2 or MPEG4/AVC, but it is most likely to be the latter one. There's no Closed Captioning. Some digital channels broadcast optionally original sound along with DVB softcoded subtitles. For analogue TV voiceover is used instead of full dubbing [with movies for children being an exception]. Sound varies for analogue broadcast from mono, thru NICAM and Zweiton [A2] up to Dobly Digital. Digital broadcasts usually transmit in stereo or AC3

How do you know if your tv is digital?

"Digital" is a very vague term for televisions. A telelvision can be called digital if any part of the signal path uses digital data. Therefore, any plasma or LCD telelvision is digital as they all use digital signals in generating an image. The question probably refers to digital inputs. If it has a digital receiver built in, for terrestrial digital broadcasts (UK Freeview, for example) or has a digital cable decoder, then it can be called digital. In these cases, the manual will point out that it is a digital TV. If the television has HDMI or DVI inputs, both of these are digital inputs and it is therefore a "digital" television. A better definition of "digital" in this question would get a better answer.
