Broadcast regulator Telecom Regulatory Authority of India will hold a meeting with the stakeholders on Thursday to discuss how to roll-out conditional access system in the metros.

"The meeting will be held tomorrow with the major multi-system operators and government officials of Delhi, Mumbai and Kolkata to discuss feasibility to how to go forward in non-CAS areas," a Trai official said on Wednesday.

CAS has been implemented in Chennai since 2003.

"Keeping in view the confusion among the MSOs and consumers in the first phase on installation of set top box to watch satellite channels through CAS in specified areas, they will be asked about their preparedness this time to implement it," said the official.

During the meeting, Trai will see how many STBs had been installed on ground and also try and understand the problems consumers as well MSOs were facing because of the new system implemented four months ago.

CAS, which is a digital content delivery model, rolled out in specified areas of Delhi, Mumbai and Kolkata from December 31 following orders from Delhi high court.

In Delhi, against an estimated four to five lakh TV sets in the notified area, MSOs have been able to penetrate 70 per cent of households, a Delhi government official said.
