ery of IP-encapsulated data over terrestrial networks. In March 2008 the European Commission endorsed DVB-H as the recommended standard for mobile TV in Europe, instructing EU member states to encourage its implementation. DVB-H is an extension of DVB-T (DVB-Terrestrial) with some backwards compatibility, that is, it can share the same multiplex6 with DVB-T. Figure 9.10 [16] shows the conceptual view of a DVB-H system. The transmitter section consists of a DVB-H IP-encapsulator and a DVB-T modulator whereas the receiver consists of a DVB-T demodulator and IP-decapsulator. The central features of DVB-H technology are time slicing, multiprotocol encapsulation-forward error correction (MPE-FEC) and 4K mode and in-depth interleavers. Time Slicing: Time slicing enables significant power savings in the receiver. Each individual TV service in a DVB-H signal is transmitted in bursts allowing the receiver to go into sleep mode, only waking up when the service to which it is "tuned" is transmitted. Figure 9.11 shows an example of the time slicing feature where it is assumed that about three quarters of the DVB-T data rate is allocated to three TV programs and the remaining 3.2 Mbps are used for DVB-H services. In contrast to the TV programs which require a continuous flow of data, the DVB-H capacity is divided (i.e., time-sliced) into eight individual services each occupying what is called a time-slice in the DVB-H terminology. The service data rate available for each of the eight services is 0.4 Mbps (3.2 Mbps/8). During each time slice 2 Mb (burst size) are transported to the receiver which in consequence means that the duration of the time slice is 2/3.2 = 0.625 seconds. Thus, if a receiver is tuned to service number 1 it can go into power save mode for the period of time during which servicesnumbers 2 to 7 are being transmitted [17]. The time slicing on the other hand can have an impact on the viewing experience causing a noticeable delay in signal acquisition when the user switches from channel to channel. The use of
