ETSI TR 101 202

The present document provides implementation guidelines for the use and implementation of the Digital Video Broadcasting (DVB) data broadcast service in a DVB digital broadcast environment including satellite-, cable-, MMDS- and terrestrial networks.

The guidelines are intended to be highly recommended rules for the usage of the DVB data broadcast specification as put down in EN 301 192 [1]. As such, they facilitate the efficient and reliable implementation of data broadcast services. The rules apply to broadcasters, network operators as well as manufacturers.

The rules are specified in the form of constraints on the data broadcast implementation.

The specification of these functions in no way prohibits end consumer device manufacturers from including additional features, and should not be interpreted as stipulating any form of upper limit to the performance.

NOTE: It is highly recommended that the end consumer device should be designed to allow for future compatible extensions to the DVB data broadcast specification. All the fields "reserved" (for ISO), "reserved_future_use" (for ETSI), and "user defined" in the EN 301 192 [1] should be ignored by end consumer devices not to make use of them. The "reserved" and "reserved_future_use" field may be specified in the future by the respective bodies, whereas the "user defined" field will not be standardized.

This guidelines document uses the terminology defined in EN 301 192 [1] and should be read in conjunction with that document.
