Multi-Memory Time Shifting for Simultaneous Broadcast Recording

The patent divides the storage function into multiple separate memory units (first memory, second memory, etc.), each dedicated to a specific time shifting function. This segmentation allows the system to provide multiple time shifting functions simultaneously while keeping each memory unit's operation simple and manageable, thus increasing versatility without proportionally increasing overall system complexity.

The patent creates a universal time shifting system where multiple memory units can perform the same time shifting function (recording, pausing, rewinding) but for different broadcast programs simultaneously. This multi-functionality approach allows a single television device to serve multiple time shifting purposes, enhancing adaptability while maintaining operational simplicity through standardized function replication.

The system performs preliminary recording of broadcast programs into memory units before they are needed for time shifting playback. This preliminary action allows the television to continue receiving and displaying live broadcasts without interruption, while the recorded content is already prepared in memory for future time shifting operations, thus maintaining both productivity and continuous reception.

The patent creates copies of broadcast programs by recording them into memory units. Instead of stopping reception to manipulate the original broadcast signal, the system makes copies that can be independently processed for time shifting functions. This copying mechanism allows the original broadcast reception to continue uninterrupted while enabling multiple time shifting operations on the copied content.

The patent segments the system into independent functional units, each consisting of a memory unit and associated control logic for a specific time shifting function. This modular segmentation allows multiple time shifting functions to operate simultaneously with minimal interference, managing complexity through clear separation of functions rather than integrating them into a single complex system.

The patent manages complexity by changing the parameter of memory allocation - instead of using a single large memory with complex management, it uses multiple smaller memory units with dedicated assignments. This parameter change simplifies the control structure for each function while achieving the goal of simultaneous multi-function operation, thus improving versatility without proportionally increasing overall device complexity.
