The Clerk's Office in Parliament says some trade-offs will be required to maintain the radio and television broadcast of Parliament.
Budget documents reveal the office is under substantial financial pressure and will need to make more than $1 million in savings, representing 8% of its budget, by 2015.
Radio and television broadcasting of Parliament make up more than 10% of the Clerk's Office's budget.
The documents say the office will have to look at cutting the cost of its broadcasts to make the required savings.
Contracts covering the televising of Parliament are up for renewal next year.
The office is also having to investigate extending Parliament TV to cover select committee hearings and says it will carry out a pilot using webcasts to see if it is affordable.
The Clerk, Mary Harris, says the office will trial captioning Parliament on TV and webcasting select committee hearings on Parliament's website later this year.
