Figure 2-1: Components of the transmission system DVB-H
The current firmware does not support hierarchical coding including low-priority coding.
The Low-Priority (LP) path of the MPEG-2 Stream indicates this by dotted squares of
the low-priority coding procedure.
DVB-H provides features to meet the specific requirements for handheld, mobile termi-
nals such as:
●
Power off some part of the reception chain to increase the battery duration
●
Ease access to the services when receivers switching to the next cell
●
Mitigate the effects of man-maid noise and severe mobile multipath channels on
the receiving capabilities
●
Offer sufficient flexibility and scalability to allow reception of services at various
speeds
●
Offer the flexibility to be used in various transmission bands and channel band-
widths
The basic technical extensions that make it possible to receive digital video broadcast-
ing services on handheld terminals are:
●
4K mode and in-depth interleavers
●
Time-slicing
●
Forward error correction for multiprotocol encapsulated data (MPE-FEC)
