Irma Inaishvili, the head of the union, said a mobile television center will be set up on a square near the State Chancellery building to broadcast directly to large screens erected on streets across the country's capital.
She said that the "Objective" television studio had recently had its broadcasting license revoked and "today our place is on the streets."
The "free TV on the streets" project she said is aimed at covering human rights violations in the country and will also give ordinary people a chance to discuss recent developments.
Georgia's opposition has been holding virtual round-the-clock protests to demand President Mikheil Saakashvili step down since April 9. Currently protesters are gathered at the State Chancellery building, where the offices of the prime minister and other state ministers are located, outside parliament, the presidential residence and state television headquarters.
Saakashvili's opponents blame him for dragging the country into a war with Russia over South Ossetia last August, resulting in the permanent split from Georgia of the province, along with another former republic, Abkhazia. He also faces criticism for failure to carry out democratic reforms promised after the 2003 "Rose Revolution" that brought him to power.
