The three Coalition leaders have met to finalise an external review of RTÉ, which will be considered by Cabinet.
It follows revelations of non-disclosed payments by RTÉ to presenter Ryan Tubridy totalling €345,000 over several years.
The party leaders were also expected to sign-off on a proposal to allow for the appointment of an auditor to review RTÉ finances.
Tánaiste and Minister for Foreign Affairs Micheál Martin said there has to be a "rebalancing" in RTÉ and the public service ethos must be restored.
There is a sense, he said, of a need for a "strong, coherent governance structure" and that it is "an opportunity to take a root and branch look at this".
Mr Martin said: "I think the ethos of the whole sense of public service is something we need to work on with RTÉ to make sure that's restored, because that's very important."
Speaking on RTÉ's News At One, he added: "My own observations are that there has to be a rebalancing in terms of the public service ethos of the station and the commercial activity – which is essential, let's be frank."
There was concern, he said, of how the culture of the agent "seems to have been predominant over the collective".
"It does worry me at times, if I may say so and this is just an observation, that RTÉ can work in silos – that every programme is like an independent republic and that needs to change.
"And there needs to be more of a sense of the collective approach."
The broadcaster has confirmed that four senior executives, who attended two Oireachtas committees last week, will be back before the Joint Oireachtas Committee on the Media this Wednesday.
They are Interim Deputy Director General Adrian Lynch, Chief Financial Officer Richard Collins, Director of Commercial Geraldine O'Leary, and Director of Strategy Rory Coveney.
It's also been confirmed that two members of the RTÉ Board will also attend. They are Chairperson Siún Ní Raghallaigh and RTÉ staff representative Robert Shortt.
Other invitees include the former director general Noel Curran, former chief financial officer Breda O'Keefe and former chair of the RTÉ Board Moya Doherty.
The RTÉ Board is a body made up of 12 people that makes policy for the broadcaster, while the Executive Board is a committee composed of senior management responsible for its day-to-day running.
Minister for Public Expenditure Paschal Donohoe said that "far, far more clarity and transparency" was needed around how the existing pay policy at RTÉ was implemented and said it was not acceptable to the Government, the Oireachtas and the TV licence fee-paying public that the wrong information was given to them.
Asked whether details of RTÉ finances and accounts going back decades were needed, Mr Donohoe said: "I'm not sure if decades was warranted. It does appear that we're going to need information that did stretch back a number of more years than is currently available."
Mr Donohoe said the terms of reference of the external review should go back far enough "to give confidence that we got to the bottom of what's going on".
Call for salaries to be capped
Earlier, Independent Senator Rónán Mullen proposed that salaries in RTÉ should be capped in line with the money received by a government minister.
Speaking on RTÉ's Morning Ireland, he said: "Essentially it is the Restriction of Salaries Bill which comes to its second stage debate in the Seanad this Wednesday."
He said the bill would provide the first ever legislation of its kind that salaries would be capped in public broadcasting.
"It refers to the corporation so we're talking about RTÉ and TG4 under the broadcasting legislation," Mr Mullen said.
"My legislation would amend that legislation to provide that no matter how the salary is constructed, whether by way of direct employment or any set of contracts with external people, that the remuneration cannot exceed the annual salary allowance of the minister.
"The minister being the Minister for Communications."
He said that is a figure of €195,000 and that some people might say it is too high, while others might say it is too low, but the principle is important.
Senator Mullen added that a balance in pay scales is needed.
He said the legislation proposes a cap, transparency around any salary over €107,000, which is the TD salary equivalent.
"And it also provides that there are penalties for knowingly causing inaccurate information about salaries that would apply under the bill as well," he said.
Mr Mullen also said that the bill recognises that one of the benefits of being a celebrity or being "a very known name" in the likes of RTÉ, is that the person has the opportunity to monetise their value in other ways through external appearances.
The Tánaiste said the bill is "simplistic" and "popular to say". He said he would be "slow to go in for the cap" and that "I would much prefer to look at the pay and conditions of those who are not earning anything like that in RTÉ and get that right".
"Everyone gets lost on the top ten but there's hundreds of people working in RTÉ on average salaries," he said.
Mr Martin said that "the actual working out of that [the pay cap] over time can be actually more problematic than people might think right now".
Senator Mullen said he is looking forward to hearing what the minister will say on Wednesday and if the Government will embrace the bill.
Minister of State Jack Chambers said he does not believe "ordinary workers in RTÉ should pay the price for dysfunction at senior management".
Speaking on RTÉ's Today with Claire Byrne, he said there is a "need to have public service broadcasting beyond this point", and the opportunity is being used "to bring reform, to put RTÉ in a place of proper governance and restore trust and confidence in the organisation".
Mr Chambers said anyone asked to appear before Oireachtas committees in relation to this should.
"I think the drip feed [of information] that we saw last week didn't yield confidence and I think anyone who’s asked should appear and put all the facts on the table," he said.
Cork operations
Meanwhile, RTÉ issued a statement this morning in which it said it remains fully committed to its operations in Cork.
It said: "Contrary to speculation, RTÉ remains fully committed to its operations in Cork.
"The suitability of the current building for the full range of RTÉ's operations in Cork is being assessed."
Meanwhile, Roddy Flynn, Lecturer in Dublin City University's School of Communications, said the urgency regarding discussions about how RTÉ is funded - in particular the public element of it - has increased.
Speaking on RTÉ's Today with Claire Byrne, he said the blurring of RTÉ's identity as both a commercial broadcaster and a public service broadcaster "is what has brought us to this place".
"A dual funding model is not uncommon, but the extent of RTÉ's reliance and the extent to which RTÉ has been kind of forced to be reliant on commercial income is unusual by European standards," he said.
"It's unusual by public service broadcasting standards in general."
Mr Flynn said the reliance on the commercial side is "plummeting".
He said in 2007 at its peak it was about €245 million and it is now down to €145 million.
