1. An apparatus, comprising:

  • a Bluetooth communication transceiver configured as a Bluetooth low energy device, for receiving communication packets having a packet length and containing digital content information useful for reducing a receive window duration;

    a timer configured to perform at least one timing measurement for power saving used for measurement of a connection interval to be used for reducing a size of an activation window; and

    a processor configured to adjust a receive timing of the Bluetooth communication transceiver in response to detecting the digital content information in the received communication packets, wherein the processor is configured to detect a logical link identifier field in a header of a received packet by the Bluetooth communication transceiver and adjust an end time of the receive timing of the Bluetooth communication transceiver to reduce the receive duration depending on a content of the logical link identifier field, by turning off the activation window early, in order to reduce the receive window duration, thereby reducing a portion of the packet length received, based at least in part on the at least one timing measurement, the processor configured to continue the reduced receive window duration as long as the received communication packets contain the digital content information.
