The ABC's coverage of Anzac Day services and parades across Australia are an important part of the solemn remembrance ceremonies that take place across the country.

This year's broadcast by 774 ABC radio in Melbourne included the Anzac Day dawn service at the Shrine of Remembrance, as well as live crosses using a roving Tieline Commander codec over the Telstra Next G broadband cellular network.

"The ABC's roving reporter did live crosses into the Anzac Day broadcast from the corner of Swanston and Flinders Streets in the heart of the city," said Glynn Sherris, Tieline's Australasian Business Development Manager. "They also did live crosses with interviews from inside Young & Jacksons Hotel and while they were walking up St Kilda Road. They chatted to people in the crowd and war veterans, which really brought the emotion of the day into the homes of people listening to the broadcast."

The reporter carried the codec in a backpack with a hand-mike plugged in and a set of headphones for listening to studio IFB. "The feedback about the performance of the codec was extremely positive," said Sherris. "An ISDN line was used at the Shrine which was the main remote broadcast site and we were told that the Tieline codec 3G signal going directly back to the central studios actually sounded better than the ISDN signal."

The codec connected to the cellular network at 48kbps using a default mono profi le and sent very high quality broadcast audio with low delay using Tieline's Music algorithm. To achieve this the Commander used a Tieline HSDPA plug-in module with a standard Telstra Next G SIM card. It dialed and connected to a Commander G3 rack unit codec installed in the station's Master Control area.

"774 ABC have a great IFB system that provides a mix-minus feed from each of their studios," said Sherris. "This can be routed very simply into the Commander studio codec and sent to the Commander codec at the remote OB site - making live crosses really easy to set up."

"The portability of the Commander codec and the capabilities of 3G broadband have created exceptional opportunities for remote broadcasting," said Sherris. "It has literally taken radio to the people and the possibilities are unlimited."
