Digital is manditory, not HD. And it only effects CATV companies and those who receive off of antenna. Digital broadcasting uses less bandwidth. An analog channel uses 6mhz, where as a digital can use 1/12 of that for one channel. HD channels use substancially more than a standard digital channel.
People's basic tier channels will still be analog NSTC format - for the time being. |
It DOES NOT effect CATV (well a little indirectly) it is ONLY broadcast TV that will be moved to digital.. in fact CATV MUST provide local and certain other "MUST CARRY" channels in unencrytped analog format until AT LEAST 2013 or provide all subscribers who request them with digtal to analog converters for free. only a couple small cable co have chosen the converter route. (the cost is huge, but may be cheaper for small providers than converting and sending both digital and analog signals) a few very small systems have won exemptions from the rule (less than 1000 subscribers less than 3 local/must carry stations)
if you have basic cable, no worries until 2013 at the earliest (FCC has a record of repeatedly extending these deadlines) if you use a cable box no worries, only Broadcast only users with analog sets need to make any changes. |
