CAS for Cable TV Network
1. Set Top Box (STB) provided by the MSO are network specific and can't be used in other network. As an example, if a STB is provided by DigiCable that can be used only on DigiCable network or if the STB is provided by Hathway that can be used only on Hathway. This STB can't be used in other network. As a result, if you are not satisfied with any MSO, changing of the MSO will cost more and previous STB will be unused. On other hand, if you change your residence and previous MOS is not available in your local area your STB will become unusable. As like mobile hand set, TRAI should recommend universal access STB which can be used through all network and user should purchase only CHIP for the desired MSO (as like SIM card of the mobile service provider). Only changing of "CHIP" can change the MSO and new STB will not be required.
2. Using of CAS is increased average view cost of cable TV, specially in rural area. TRAI should develop such policy that will increase competition among the MSO and help to control viewing cost. more
