Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, electronic media presentation of audio and video, and wearable/mobile computing devices configured to facilitate communication among electronic devices, including mobile phones and media devices that present audio and/or video content. More specifically, disclosed are systems, components and methods to autonomously discover and/control operation of devices, such as media devices, by modulating and demodulating packet characteristics to establish an overlay communication channel. In various embodiments, a method includes receiving at least one RF channel including an overlay communication channel over which packets convey message data modulated with characteristics of the packets. The method includes selecting the RF channel and demodulating a subset of the packet characteristic values to form extracted symbols. At least one method can select a device that autonomously discovers another device using modulated packet characteristics. |
