| Abstract: | This paper introduces two different handheld TV broadcasting technologies based on different networks: MMBS and CMMB. The analysis of the above mentioned standards and simulations of these systems show that CMMB is better than MBMS in terms of network structure, cell capacity, service bit rate and image quality; however, the interactive applications of MBMS outweigh those of CMMB. |
