SubStation Alpha

SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a subtitle file format created by CS Low (also known as Kotus) that allows for more advanced subtitles than the conventional SRT and similar formats. This format can be rendered with VSFilter in conjunction with a DirectShow-aware video player (on Microsoft Windows), or MPlayer with the SSA/ASS library. It is also the name of the popular, now discontinued tool used to edit subtitles.

This subtitle format is frequently used in anime fansubs, either to overlay subtitles onto video while it is being encoded (hardsubbing), or to store subtitle data alongside video data in a Matroska (MKV) container (softsubbing). Hardsubbing is irreversible but does not require VSFilter or other special resources for playback. Softsubbing allows the end user to choose whether subtitles will be displayed, and makes it possible to include multiple subtitle streams in the same video file.

The current version of SSA is v4.00.

There are many freeware and open source subtitling applications that support the SSA format.

HIT 107

Hit 107 (call sign: 5SSA) is a commercial FM radio station in Adelaide, South Australia primarily targeted at those in the 16–35 age group on a frequency of 107.1 MHz, and part of Southern Cross Austereo's Hit Network. On Monday 13 October 2014, it was announced that SAFM would cease broadcasting, and would relaunch on Monday 20 October 2014 as hit107 due to flagging ratings.

History

The station commenced broadcasting in 1980, on the frequency of 107.5 MHz, with a call sign of 5SSA and an original on-air ID of "Triple SA-FM" which was very short lived but soon replaced by "Double SA-FM". It was the first commercial radio station to broadcast on the FM band in Adelaide. Initially SA-FM was somewhat of a fringe operation, hampered largely by the fact that many houses, and more importantly most contemporary cars, did not have the ability to receive FM radio broadcasts.

Later, it changed its name to "SAFM", and altered its frequency slightly to 107.1 MHz. A second frequency, 91.1 MHz, was added as what was the first of many repeater frequencies in Adelaide, required due to Adelaide's sometimes problematic television and radio reception idiosyncrasies.
