In this letter, we study a hybrid Multimedia-on-Demand (MoD) system which provides broadcast, batch and interactive services. An analytical model for such an MoD system is provided. Numerical results show that with proper design, the system can provide better performance than those systems which only provide any subset of two services.

In this letter, we take advantage of both types of Interactive and Batch services by considering a hybrid multimedia-on-demand (MOD) system which provides both services. Also, we propose two serving methods with an incentive charging scheme to optimize the coexistence of both services. Numerical results show that the proposed hybrid system outperforms both individual systems. In particular, the system provider receives more revenue by serving more users concurrently, while the users have a better viewing experience due to higher availability of contents.

We study the user reneging behavior in a hybrid Multimedia-on-Demand (MoD) system, which provides both interactive and batch services. Reneging happens when users become reluctant to wait for a batch service and quit the service. They will either join the interactive service or quit the system. In this letter, the analytical model for the MoD system with user reneging behavior is provided. Numerical results show that the reneging behavior has a significant impact on system performance. Therefore, careful consideration on reneging behavior should be made for designing a MoD system.
