in soft/softer handovers on the E-DCH will be slightly different from that specified in R99 for the DCH; namely the main serving Node B will be able to issue both power-up and power-down commands but all other Node Bs participating in the handover will be able to issue only power-down commands. A power-down command will always take precedence over a power-up command. Table B.51 shows the six different UE categories defined, which are mainly characterised by the number of parallel codes supported and the support of 2-10 ms TTI. Appendix C Digital Video Broadcasting Lino Dalma Digital video broadcasting, handheld (DVB-H), is a new European standard for mobile television. The standard is derived from the digital terrestrial television standard DVB-T (DVB, terrestrial) by adding enhancements for the reception in the mobile environment and integration with mobile networks. Devel- opment of mobile television is an interesting challenge from the technology point of view. There is also even a bigger challenge in predicting prospects of services based on mobile TV and their commercial aspects. This presentation gives an overview of mobile TV technology and issues of its integration with other broadband wireless systems. C.1 Introduction Digital television went through a full cycle of development: from basic research via standardisation to commercial introduction and building a significant market share. Today there is talk of finishing analogue TV broadcasting completely, first in some leading areas like Finland or the UK and later everywhere. The progress of technology enabled another cycle of development to start in the area of television. This time television is being addressed to mobile devices which, judging by their numbers and variety, may open entirely new perspectives. Nowadays, however, the mobile TV has moved merely from the basic to the standardisation process SO only its deployment later will judge its success. The current state of affairs offers in turn some period in which research and development can still
