Standard-definition television (SDTV) is a television system that uses a resolution that is not considered to be either enhanced-definition television (EDTV) or high-definition television (HDTV). The term is usually used in reference to digital television, in particular when broadcasting at the same (or similar) resolution as analog systems. The two common SDTV signal types are 576i, derived from the European-developed PAL and SECAM systems with 576 interlaced lines of resolution; and 480i, based on the American National Television System Committee NTSC system.
In the US, digital SDTV is broadcast in the same 4:3 aspect ratio as NTSC signals. However, in areas that used the PAL or SECAM analog standards, standard-definition television is now usually shown with a 16:9 aspect ratio, with the transition occurring between the mid-1990s and mid-2000s. Older programs with a 4:3 aspect ratio are shown in 4:3.
Standards that support digital SDTV broadcast include DVB, ATSC and ISDB. The last two were originally developed for HDTV, but are more often used for their ability to deliver multiple SD video and audio streams via multiplexing, than for using the entire bitstream for one HD channel.[clarification needed]

Play the halls
See the stalls tonight
Open roads the like
Across the dateline change will never strike
Australia lies ahead
Australia, we head for the mainland
Clutching our gifts from the East
Only to find out
Planes and the highways
STrain the paths and the by-ways
Remain, still it's leading me
Closer to you
Australia, we're leaving you behind
Australia, we're taking the easy way out
From now on
"Come to," can't get away from ya still
"Come to, we'll take good care of ya."
Australia, you save your face while fashions slip
Australia, you're balanaced between
The powers' tightening grip
I've been to, it's a long way for ya still
