ABSTRACT
Broadcasting is an excellent way of reaching many users with a single service, that is, one-to-many communications, and this is the approach adopted by Digital Video Broadcasting-Handheld (DVB-H), allowing dozens of channels. DVB-H is a technology standard for the transmission of digital TV and broadcast services to handheld devices such as mobile telephones and personal digital assistant. DVB-H is a physical layer specification designed to enable the efficient delivery of Internet Protocol-encapsulated data over terrestrial networks. The DVB-H standard is built upon the principles of the digital video broadcasting–terrestrial (DVB-T) standard, and adds functional elements necessary for the requirements of the mobile handheld reception environment. DVB-H is an extension to DVB-T with some backwards compatibility. For a DVB-H receiver to be integrated in a mobile device, three key issues must be addressed: reduction of the power consumption, maintaining of performance in mobile environments, and achievement of the minimum mechanical size.
