How has digital technology changed television?

Digital technology has changed television in several ways. The use of timecoding on digital footage allows for much faster and efficant editing, whereas analoge footage would involve scouring tapes, digital coupled with the use of computers means footage can be skipped to, cut and changed much more easily. Due to digital, HD can be transmitted and recived. This is due to the way the signal is transmitted and invites much less interferece. A digital style file can be much more easily merged with electronic devices. This is since these devices work on a digital digital format. Example of this are Youtube, syncing film with iPods, on demand television services. A greater number of channels can be sent on one bandwidth since digital signals can be compressed, yet this was not possible with an analouge signal.
