Abstract:
A personal video recording (PVR) system and method for allocating limited memory space to multiple users for recording programming content. A selected amount of storage space for storing programing content is allocated for each PVR user. Based on a storage priority protocol, such storage space allocation may change (i.e., increase or decrease) dynamically for additional PVR users. Further, the accessibility of recorded programming content by one or more PVR users and viewing thereof may be subject to different access rights accorded to the users. Based on predetermined storage access and content access protocols associated with each PVR user, certain restrictions may be placed on one or more of these users. For example, a first restriction may relate to the type of programming content that can be recorded or displayed by the PVR for specific user(s). A second restriction may limit designated users from accessing programming content that is stored but associated with another user.
