Governments can also require all receiving equipment sold in a country to support the necessary digital 'tuner'.īefore digital television, PAL and NTSC were used for both video processing within TV stations and for broadcasting to viewers. In addition, governments can also have a say with the broadcasters as to what digital standard to adopt – either DVB-T, ATSC, ISDB-T, or DTMB. Government intervention usually involves providing some funding for broadcasters and, in some cases, monetary relief to viewers, to enable a switchover to happen by a given deadline. In most places this has already happened, where a broadcaster has offered incentives to viewers to encourage them to switch to digital. As digital becomes more popular, it is expected that the existing analogue services will be removed. Usually during a transition, a simulcast service is operated where a broadcast is made available to viewers in both analogue and digital at the same time. HDMI) which can be received on the older TV. It is an involved process because the existing analogue television receivers owned by viewers cannot receive digital broadcasts viewers must either purchase new digital TVs, or digital converter boxes which have a digital tuner and change the digital signal to an analog signal or some other form of a digital signal (i.e. By contrast, transition of satellite television systems was well underway or completed in many countries by this time. Transition of land based broadcasting was begun by some countries around 2000. The transition may also involve analogue cable conversion to digital cable or internet protocol television, as well as analog to digital satellite television. Conducted by individual nations on different schedules, this primarily involves the conversion of analogue terrestrial television broadcasting infrastructure to digital terrestrial (DTT), a major benefit being extra frequencies on the radio spectrum and lower broadcasting costs, as well as improved viewing qualities for consumers. The digital television transition, also called the digital switchover ( DSO), the analogue switch/sign-off ( ASO), the digital migration, or the analogue shutdown, is the process in which older analogue television broadcasting technology is converted to and replaced by digital television. No digital switchover planned, broadcasting both analogue and digital signals Transition has not been planned or started, or is in early stages Transition in progress broadcasting both analogue and digital signals
