Implementing Statistical Multiplexing in DVB-H

الملخص EN

A novel technique for implementing statistical multiplexing (StatMux) of broadcast services over Digital Video Broadcasting for Handhelds (DVB-H) channels is proposed.

DVB-H uses a time-sliced transmission scheme to reduce the power consumption used for radio reception part in DVB-H receivers.

Due to the time-sliced transmission scheme, the implementation of known StatMux methods for DVB-H application presents some challenges which are addressed in this paper.

The proposed StatMux technique is implemented in conjunction with the time-slicing transmission scheme.

The combination is similar to a time division multiplexing (TDM) scheme.

The proposed StatMux method considerably decreases the end-to-end delay of DVB-H services while it maximizes the usage of available bandwidth.

Moreover, the proposed method can effectively decrease the channel switching delay of DVB-H services.

Simulation results show a high performance for the proposed StatMux method.
