Notes on DVB-H

Introduction
• Convergence of digital media and communication give users
possibility to consume most digital content also in mobile environment
• The emerging DVB-H standard aims to provide digital TV reception in
mobile devices (earlier known as DVB-X)
• DVB-H is being standardized by and ad hoc group of the DVB
organization
– Proposal submitted to ETSI in the first quarter of 2004
• DVB-H combines traditional television broadcast standards with
elements specific to handheld devices; mobility, smaller screens and
antennas, indoor coverage and reliance on battery power
Motivation for creating DVB-H
• Why not use UMTS?
– Not scalable for mass content delivery
– For delivery of mass media content, broadcast networks should be
preferred over point-to-point cellular networks
• Why not use DVB-T?
– Was designed for rooftop reception
– Need for an efficient power saving mechanism
– Inadequate impulse noise protection
• Why not use DAB?
– Designed to better fulfill power constraints; but!
– Capacity left for data transmission is expected to be limited
(primary usage for audio)
HOWEVER! DAB is technologically the best suited system!!!
