The Spanish government has introduced two new pieces of legislation for its digital TV markets, mandating clarity and shaking up muxes from its HD operators.
The new legislation obliges broadcasters to inform viewers when a broadcast is shown in HDTV. This change's goal is all the citizens have more information and at the same time know at any moment when they are receiving HDTV content.
Broadcasters will now only be able to put a signal on their screens that a certain TV programme is being offered in HDTV when such a programme has been produced and edited in its origins and with a vertical resolution equal greater than 720 active lines in 16:9 format.
The other modification introduced in the Royal Decree affects the distribution of DTT muxes after the forthcoming analogue switch off comes and is designed to lead to greater efficiency of the compression systems for the A/V signals. This should allows TV content to display improved technical quality or even increase the number of channels that can transmit within the same mux.
Some broadcasters have already begun to broadcast simultaneously some DTT signals in HDTV meaning a superior quality service.
The Decree also removes the previous limitation through which broadcasters must share assigned capacity by each exploiting two DTT channels in each mux. They must now share this capacity through exploiting half of each mux on an equal basis and so broadcasters will only be able to broadcast four DTT channels.
