In Digital Video broadcasting there are two types of information namely global and local content. Broadcasting both information using multifrequency network requires large spectrum. To overcome that single frequency network is incorporated.Inorder to transmit both the information in a single frequency network, a novel technique, namely selected subcarrier method of Digital Video Broadcasting is proposed. This technique is well suited in a scenario where the transmission of two different information is targeted over the entire globe at the same time. This methodology proficiently handles the concept of Orthogonality principles among the OFDM subcarrier. In this technique certain dedicated subcarrier is used for transmission of Local content in the network.Also, wavelet-based OFDM has been proposed, which outperforms the existing Fourier based OFDM
