Australian CTV Multiplex Transport Stream Analysis

DVB-T TV
TVS, or Television Sydney, is a free-to-air community television station broadcasting in Sydney, Australia. Transmissions officially commenced on analogue UHF channel 31 in February 2006 after three months of technical trials. In November 2009 the Australian Government agreed to temporarily allocate TVS (and the other capital city Community Television channels) an additional (digital) channel so they could simulcast in the period up until the end of 2013 when analogue television will be turned off. TVS announced in December 2009 that it had appointed Broadcast Australia as its digital service provider and officially began simulcasting on Monday 1 March 2010 on Logical Channel Number 44.

The data was captured on 13 Jul 2011 by Andrew Somerville.
