Receiver software is increasingly complex. In order to guarantee the functionality of a receiver as well as increasing its
functionality once deployed in the field a software update service is required. The present document specifies a standard
mechanism for signalling a software update service and the means to carry the data for such a software update service.
It builds on ISO/IEC 13818-6, ETR 162 and EN 300 468 for signalling and EN 301 192 for data carriage.
The present document does not define the mandatory character of this protocol in a specific context, and it does not
exclude the use of proprietary mechanisms for doing a software update. This allows a network to support horizontal
market model receivers (e.g. MHP receivers). Equally it allows receivers requiring a software update service to be
deployed in a network independent way.
