The ParentalRatingScheme class
Support in HbbTV
Available since: HbbTV 1.0 (ETSI TS 102 796 V1.1.1, OIPF DAE V1.1)
A scheme supporting DVB-SI age based rating shall be supported. The threshold.value and threshold.name properties shall be undefined if the user has set no minimum age in the terminal’s parental control system (i.e. the user will never be requested for their PIN) and the threshold.scheme property is dvb-si.
typedef Collection<String> ParentalRatingScheme
A ParentalRatingScheme describes a single parental rating scheme that may be in use for rating content, e.g. the MPAA or BBFC rating schemes. It is a collection of strings representing rating values, which next to the properties and methods defined below SHALL support the array notation to access the rating values in this collection. For the natively OITF supported parental rating systems the values SHALL be ordered by the OITF to allow the rating values to be compared in the manner as defined for property threshold for the respective parental rating system. Using a threshold as defined in this API may not necessarily be the proper way in which parental rating filtering is applied on the OITF, e.g. the US FCC requirements take precedence for device to be imported to the US.
The parental rating schemes supported by a receiver MAY vary between deployments.
See Annex K for the definition of the collection template. In addition to the methods and properties defined for generic collections, the ParentalRatingScheme class supports the additional properties and methods defined below.
Properties
| readonly String name |
| The unique name that identifies the parental rating scheme. Valid strings include: · the URI of one of the MPEG-7 classification schemes representing a parental rating scheme as defined by the “uri” attribute of one of the parental rating <ClassificationScheme> elements in [MPEG-7]. · the string value “urn:oipf:GermanyFSKCS” to represent the GermanyFSK rating scheme as defined in [OIPF_META2]. · the string value “dvb-si”: this means that the scheme of a minimum recommended age encoded as per ratings 0x01 to 0x0f in the parental rating descriptor from [EN 300 468], is used to represent the parental rating values. NOTE: If the broadcaster defined range from 0x10 to 0xff is used then that would be a different parental rating scheme and not “dvb-si”. If the value of “name” is “dvb-si”, the ParentalRatingScheme remains empty (i.e. ParentalRatingScheme.length == 0). |
| readonly ParentalRating threshold |
| The parental rating threshold that is currently in use by the OITF’s parental control system for this rating scheme, which is encoded as a ParentalRating object in the following manner: If the value of the “name” property of the ParentalRatingScheme object is unequal to “dvb-si”, then: · the “value” property of the threshold object represents the value for which items with a ParentalRating.value greater or equal to the “value” property of the threshold object have been configured by the OITF’s parental control subsystem to be blocked. · the “labels” property of the threshold object represents the bit map of zero or more flags for which items with a ParentalRating.labels property with any of the same flags set have been configured by the OITF’s parental control subsystem to be blocked. If the value of the name property of the ParentalRatingScheme object is “dvb-si”, the threshold indicates a minimum recommended age encoded as per [EN 300 468] at which or above which the content is being blocked by the OITF’s parental control subsystem Note that the value property as an index into the ParentalRating object that defines the threshold can be 1 larger than the value of ParentalRatingScheme.length to convey that no content is being blocked by the parental control subsystem. |
