Although the amount of multimedia content delivered over mobile networks is increasing exponentially, the cost of accessing multimedia content represents a problem for many users. Furthermore, internet service providers are capping mobile data plans and this can lead to increased prices for mobile multimedia content users. This paper briefly presents the Cost Oriented adaptive MultimEdia DeliverY (COMEDY)- a mechanism that aims to reduce the cost of multimedia delivery over wireless networks by decreasing the bitrate and resolution of the multimedia clips. COMEDY takes into account the user's attitude towards risk when the adaptation is performed. The viewer trade-off between multimedia quality and the delivery cost is analysed. The results have shown that the price to be paid for accessing the adapted multimedia clip is considerably reduced for the case when the COMEDY mechanism was used.
