Statistical Time-Frequency Multiplexing of HD Video Traffic in DVB-T2

الملخص EN

Digital video broadcast-terrestrial 2 (DVB-T2) is the successor of DVB-T standard that allows a two-dimensional multiplexing of broadcast services in time and frequency domains.

It introduces an optional time-frequency slicing (TFS) transmission scheme to increase the flexibility of service multiplexing.

Utilizing statistical multiplexing (StatMux) in conjunction with TFS is expected to provide a high performance for the broadcast system in terms of resource utilization and quality of service.

In this paper, a model for high-definition video (HDV) traffic is proposed.

Then, utilizing the proposed model, the performance of StatMux of HDV broadcast services over DVB-T2 is evaluated.

Results of the study show that implementation of StatMux in conjunction with the newly available features in DVB-T2 provides a high performance for the broadcast system.
