The transition from SD into HD is currently progressing in many countries as a key element of the global switchover from analogue to digital transmission. Like many new technologies, HD was a classic case of the chicken-and-the-egg:
Why broadcast in HD if no-one is equipped to view the output? That has now turned on its head with 1080-line rapidly becoming the native display resolution for domestic television receivers. Given a respectable transmission bitrate, digitally delivered 1080i viewed on a 1080-native screen is nothing short of breathtaking.
Almost every broadcaster currently delivering an SD service is looking to upgrade to HD when market conditions are right.
