Internet protocol (IP) and transport stream (TS) based service access

IEC 62455:2010 specifies the terminal for a service purchase and protection system for digital broadcasts, called the 18Crypt system. It is applicable in all countries and regions with suitably compliant broadcasting and multimedia distribution systems. Guidelines for compatible broadcast services are given in this standard. The service purchase and protection functions operate in a pure broadcast environment that may be combined with a bi-directional interactivity channel. It is applicable to the following broadcast systems:
- IP datacast over DVB-H systems;
- DVB T/C/S systems;
- MPEG2 TS-based IP systems;
- Non-MPEG2 TS-based IP systems.
This second edition cancels and replaces the first edition, published in 2007, and constitutes a technical revision. The main changes with respect to the previous edition are:
- Recent developments in DVB and OMA standards caused some incompatibilities, which have been solved in the second edition.
- Technical errors have been corrected, missing details added.
- References have been updated to the newest available ones.

Accès aux services fondé sur le protocole internet (IP) et sur le flux de transport (TS)

L'IEC 62455:2010 spécifie le terminal d'un système d'achat et de protection de services pour diffusions numériques, appelé le système 18Crypt. Il s'applique dans l'ensemble des pays et régions qui comportent des systèmes de distribution de diffusion et multimédia conformes. Les lignes directrices pour des services de diffusion compatibles sont données dans la présente norme. Les fonctions d'achat et de protection de services fonctionnent dans un environnement de diffusion pure qui peut être combiné à un canal d'interactivité bidirectionnel.
La présente norme s'applique aux systèmes de diffusion suivants.
• Systèmes de diffusion de données IP sur DVB-H;
• Systèmes DVB T/C/S;
• Systèmes IP fondés sur TS MPEG2;
• Systèmes IP non fondés sur TS MPEG2.
L'IEC 62455:2010 annule et remplace la première édition publiée en 2007, dont elle constitue une révision technique.
Les principales modifications par rapport à l'édition précédente sont les suivantes:
• les développements récents des normes DVB et OMA ont entraîné certaines incompatibilités, résolues dans la seconde édition;
• des erreurs techniques ont été corrigées et des détails manquants ont été ajoutés;
• les références ont été mises à jour aux références disponibles les plus récentes;
• un certain nombre de corrections rédactionnelles et d'améliorations de lisibilité ont également été apportées, lorsque le texte original pouvait conduire à une mauvaise compréhension du fait de formulations peu claires ou de l'utilisation de plusieurs formes orthographiques pour un même élément.
