With the advancement in the current wireless technology standards such as terrestrial digital video broadcasting systems (DVB-T, DVB-T2, and DVB-H) and the massive usage of the Internet over mobile devices, streaming of television channels in smart phones has become a necessary advancement for mobile users. As, UMTS dominating the entire mobile market globally and with the evolution of LTE, several mobile operators are working on an MBMS framework which will help to launch mobile TV services on respective operators. This paper deals with terrestrial and mobile TV with IP multicasting and broadcasting and is aimed to improve system spectral efficiency. With the help of IP multicasting, the base station can be able to provide with significantly less spectrum by saving it from the channels which the user is not viewing currently. This case is analysed from several sets, called schemes of resource plan sets. The transmitter scheduling is dealt with by means of a Packet and Resource Plan Scheduling (PARPS) algorithm, and the simulated results are plotted in Matlab which assists in analysing the efficiency in the spectrum management and the coverage probability for the number of transmitters used for each scheme. The schemes are simulated in Matlab for different number of transmitters (2-7) in both the static and random model. The SFN schemes are offering greater coverage probability than MFN schemes, in all cases. Multicasting over Continuous Transmission Dynamic Single Frequency Network (CT-DSFN) offers a 1342% and 582% gain in Multi-user System Spectral Efficiency (MSSE) for 7 transmitters, from Broadcasting over MFN and Broadcasting over SFN respectively. For 7 transmitters, Multicasting over CT-DSFN offers a 1213% and 428% gain in System Spectral Efficiency (SSE) from Broadcasting over MFN and Broadcasting over SFN respectively.
