TV: Watching and Recording
DVB-T (Digital Video Broadcasting — Terrestrial) is a standard for broadcasting digital terrestrial television. It is how television is broadcast to the home in many countries in Europe, Africa, Asia, and also in Australia (but not China nor America). A compressed digital audio, digital video and other data is transmitted as an MPEG transport stream (MPEG-TS). Files recorded from such streams will often have a .ts filename extension, and sometimes .tsa or .tsv.
A practical digital TV tuner, for example, is the DigitalNow TinyUSB 2 DVB-t Receiver. This contains a Twinhan USB2.0 DVB-T receiver (TwinhanDTV Alpha/MagicBox II). In 2009 such USB sticks could be purchased for AUD90 (http://digitalnow.com.au/product_pages/tinyusb2.html). Similar devices were available in 2014 for around AUD30 on eBay.
In this chapter we look at setting up a TV viewing and recording platform using a DVB-T device. Other chapters cover what we might do wiht the recorded video, including Section 101.5 which covers details of editing any video.
