R1: Conventional conditional access schemes for unidirectional networks may be supported.

R2: Entitlement management messages in conventional CA schemes may be delivered over
bidirectional networks.

a) A CA agent on the VMS should support transmitting a request of its EMM to the head-end.
b) The head-end should support transmitting a response with the EMM to a terminal.
c) The head-end may push the EMM to a VMS without being requested.
R3: Rights rules for a terminal may be transmitted along with the EMM to the terminal.

R4: Rights rules for a terminal may be transmitted in an independent message to the terminal.

R5: The integrity of rights rules for a terminal shall be guaranteed during its transmission from the
head-end to the terminal.

R6: The rights control options shall be extensible for additional rules to be added in the future.

11 Copyright and rights management support for content delivery

11.1 Use case – Content payment and copyright protection
For some content providers the in-vehicle-screen and mobile phones are two different distribution
channels with different service cost and price offering. The price for an end-user to receive content
in a vehicle can be different on a mobile phone than on the in-vehicle-screen. Sometimes the end-user
should pay again to enjoy the same content in a vehicle while the content was already paid for by
mobile phone consumption. Alternatively, a content provider may allow its users to enjoy the same
content freely in vehicle if users have a paid content subscription for mobile phone consumption.
These different commercial policies across distribution channels should be enabled by the VMN and
VMS. The VMN should enable content providers to manage content-services-fee-payment across
distribution channels.

11.1.1 Requirements – Copy protection
R1: The design of the VMS should be capable of preventing multi-media contents distributed to the
VMS from being copied from the VMS to mobile phones and/or be redistributed through the VMS
hardware to external devices.

NOTE – This does not include the possibility that users record screens with other recording devices.

11.2 Privilege and account management
11.2.1 Use cases

11.2.1.1 Use case A – Parental control

Parental control may be enabled for children or teenager passengers to prevent access to restricted
content.
An identification (ID) system (e.g., traditional ID such as mobile phone number or biometric
technology ID such as face or voice recognition) and corresponding database may be necessary to
carry out parental control. The passenger may be identified as either an adult or a child.

11.2.1.2 Use case B – Content classification

To enable content and services rights management, identifying content classification may be
necessary to replicate common practice for multi-media content on other channels (e.g., movies in
theatre versus DVD). Content and services can be classified into different categories, based on age or
subscription status.
