Television Bluetooth Connection Control via Screen State Detection

The patent segments the power supply control for WIFI module and Bluetooth module independently. When the television enters standby mode with WIFI wake-up function enabled, only the WIFI module remains in activated state while the Bluetooth module is switched to inactive state. This segmentation allows remote wake-up through WIFI without continuous Bluetooth connection attempts, resolving the contradiction between adaptability and power consumption.

The patent applies preliminary action by pre-establishing the Bluetooth connection when the television is in on state before entering standby mode. The connection state and paired device information are stored in memory. When waking from standby, the television retrieves stored connection information and quickly re-establishes the connection without continuous connection attempts, thus maintaining fast connection speed while avoiding energy loss from repeated connection attempts during standby.

The patent implements dynamic state management where the Bluetooth module's operational state changes based on television power state. In on state, Bluetooth module is activated and accepts connection requests normally. In standby mode, Bluetooth module is switched to inactive state and does not respond to connection requests, eliminating voice prompts and connection attempt noise. This dynamic adjustment resolves the contradiction between ease of operation and harmful factors by making the system adaptive to different operational contexts.
