摘要： The various embodiments of the present invention disclose a system and method for initiating communication between different devices using audio frequency. The invention enables buzzers to generate monotone or limited tones for communication and data transmission. The first electronic device includes a frequency generator, an audio driver library, the buzzer or speaker, and a transmitter & the second electronic includes has an audio receiver mic, audio driver library, frequency receiver. The transmitter generates a communication request from a first electronic device to second electronic device. Further, the first electronic device and the second electronic device is installed with a buzzer application which when executed on the processor, causes the processor to enable communication between the first electronic device and the second electronic device by generating audible frequency using the buzzer/speaker.

摘要： A method for facilitating targeted secondary content delivery to a user is envisaged. The primary content is broadcast on a television accessible to a user, followed by targeted delivery of relevant secondary content onto a handheld device of the user. The secondary content deemed as being relevant to the primary content is delivered in an unobtrusive manner without altering the viewing experience of the primary content, only after verification of the viewership of the primary content. The secondary content deemed as relevant to the primary content is transmitted to a handheld device accessible to the user thereby not altering the viewing experience corresponding to the viewing of the primary content on the television. The secondary content is delivered to the handheld device via electromagnetic waves, preferably radio waves without necessitating an active internet connection for the handheld device, and without necessitating the user to remain logged-on to the handheld device.

摘要： The embodiments herein disclose an apparatus and method especially developed for the direct application in transmission involving user devices with some computational potential, allowing data transmission between two devices in a secure manner using media content. The method for the transmission of data between two devices comprises the following steps: receiving a digital data and a media content as input, encoding the digital data, embedding the digital data into a media content, modulating the data using radio frequency (RF) signals, transmitting the modulated RF signals, capturing the modulated RF signals by the receiver module, demodulating the modulated RF signal to obtain an encoded media content and decoding the media content for recovering the digital data.
