Hypervisor Virtualization for Multi-User Set Top Boxes

A hypervisor is introduced as an intermediary layer between the physical hardware and multiple virtual machines. This hypervisor manages resource allocation, virtualization overhead, and communication between multiple users accessing content simultaneously, thereby enabling multi-user functionality while containing the added complexity within a dedicated management layer rather than distributing it throughout the system.

The patent creates virtual copies of the operating system and applications through virtual machines. Each user receives a virtual instance that appears to be a separate physical system, allowing simultaneous access without requiring multiple physical devices. This copying approach enables multi-user functionality while isolating complexity within each virtual instance.

The system segments functionality by separating the physical hardware from the virtual instances. Multiple virtual machines are created as independent software segments that can be managed, deployed, and configured separately. This segmentation allows complex multi-user functionality to be achieved through software rather than hardware, reducing manufacturing complexity despite the increased virtualization layer.

A single physical system is designed to support multiple virtual machines executing different operating systems and applications simultaneously. This universal platform can serve multiple users and functions through software configuration rather than requiring specialized hardware for each function, thereby reducing hardware quantity while managing manufacturing complexity through standardized virtualization infrastructure.

The system dynamically adjusts content delivery based on network conditions and user requirements. When multiple display devices request content simultaneously, the virtual machines and hypervisor can dynamically prioritize streams, adjust quality levels, or pause non-critical updates to conserve network bandwidth. This dynamic adaptation enables improved user accessibility across multiple devices while managing network resource consumption.

The system provides partial content updates or selective streaming to multiple display devices rather than delivering complete identical streams to all devices simultaneously. By providing only the necessary content changes or using differential updates, the system reduces overall network bandwidth requirements while maintaining accessibility across multiple devices.
