non-premium subscription, then the service could be a best-effort live streaming of the
basketball game available on the cellular communication network.
2) If the person decides to resume the play of the basketball game from the time that the video
was paused previously, then the buffered recording of the basketball game on the cellular
communication network should be supported. Meanwhile, the live stream of the basketball
game on the satellite network may be available in a picture-in-picture mode.
3) When the person resumes the video of the basketball game on the application in the VMS, it
should automatically choose the preferred audio commentary track based on the viewing
records.

7.5.1.1 Requirements
To support continuous and consistent services across various networks and on multiple screens, the
following requirements are proposed:
R1: The VMSP and the VMS should allow a user to log in with the same user account by using
various devices, i.e., VMS itself, mobile phones, tablets, etc.

R2: The VMSP and the VMS should support the uploading of the user's viewing records to the VMSP.
R2.1: The VMSP and the VMS should support the configuration, by the user, of the scope of
his/her viewing records that are to be uploaded.
R2.2: The VMSP and the VMS should support the configuration, by the user, of the frequency of
his/her viewing records that are to be uploaded.
R3: The VMSP and the VMS should support the download of the user’s viewing records to various
devices.

R3.1: The VMSP and the VMS should support the configuration, by the user, of the frequency of
his/her viewing records that are to be downloaded.

R4: The VMS should support the reception, processing, and display of multiple media channels from
various networks and on different screens simultaneously.

7.5.2 Use case B – Cloud based services

Seamless connectivity between home, office and in-vehicle services will allow users to always find
the same software applications, user interfaces, language, etc., regardless of their location (home, in
the vehicle or at the office). Multimedia content, office applications and services will be the same.
However, for security and confidentiality reasons corporate data will not be made available or be
transferred to a VMS centrally managed user profile.
The VMS displays this content once the user is identified and allows access to individual data from
the cloud or from the user’s mobile phone.

7.5.2.1 Requirements
R1: A central user profile with content, applications and services excluding any corporate data is
deposited in the cloud or locally in the user's mobile phone. Each user can have different profile
versions, depending on the roles he can assume (on business, on leisure, family, etc.).
R2: VMS will identify driver/passenger(s) through its mobile phone (NFC, Bluetooth, other) or
cameras or sensors (scan of fingerprint, iris, face, other).
R3: VMS will identify which seat in the vehicle passenger has occupied in order to display the right
content at the right place.
R4: VMS accesses cloud content of passenger or the user provided profile of the mobile phone,
displays it at the place user is occupying in the vehicle and adapts the passenger comfort of the specific
place (seat and screen positioning, audio levels, temperature etc.). In case of multiple user profiles,
