Summary :

A local program insertion (LPI) scheme for video broadcasting systems is proposed by using a novel rotate-and-forward strategy, which can be widely used when a local TV tower (LT) wants to insert its own TV signals into the signals from the main TV tower (MT) without any additional resources. In the proposed LPI scheme, the bit stream of MT is firstly modulated and transmitted through coordinated constellation mapping, Alamouti encoding and OFDM modulation. Then, the LT receives the MT signals and demodulates them into constellation symbols. Finally, the bit stream of LT is mapped as “rotate bit” to rotate the demodulated MT symbols and forward to the users. We show that our proposed LPI scheme does not require extra time or frequency resources and it is also a complexity-reduced scheme for the local TV tower (LT) since bit-level decoding is not required at the LT. In addition, it can increase the network exchanging capacity in term of bits per channel use (bpcu).
