Egyptian satellite operator Nilesat on Wednesday cut transmission of Syrian state channels, as requested by the Arab League group for Syria, a Nilesat executive said.
"We have stopped transmission of the official Syrian channels, implementing the recommendations of the Arab League," the executive, who asked to remain anonymous, told AFP.
Earlier, addressing a meeting of top Arab diplomats in Cairo, Egyptian President Mohamed Morsi said it was time for the Syrian regime to step down.

"I tell the Syrian regime 'there is still a chance to end the bloodshed'. Now is the time for change... no time to be wasted talking about reform," Morsi told the Cairo meeting.
"Don't take the right step at the wrong time... because that would be the wrong step," he said.
He urged President Bashar al-Assad to "learn lessons from recent history" and step aside, in reference to Arab Spring revolts that overthrew the long-time dictators of Tunisia, Egypt and Libya.
Morsi, who was in June elected Egypt's first Islamist leader following an uprising that toppled Hosni Mubarak, urged the Arab diplomats to move quickly to resolve the Syrian conflict, which according to the Syrian Observatory for Human Rights has left 26,000 people dead since it erupted more than 17 months ago.
