Abstract

The present subject matter discloses an optimal range-assisted adaptive wireless broadcast communication. The disclosed system dynamically determines real-time position information and the best quality reception range of a broadcast transmitter generates correlated broadcast beacon packets embedded with spatial aware information. The system further generates chains of assistive beacon batches including the correlated broadcast beacon packets and transmits it by interleaving with the main adaptive broadcast stream. A broadcast receiver extracts the spatial aware information from the main adaptive broadcast streams and determines an optimal position of the broadcast transmitter with reference to self-position and co-relates this information with the extracted spatial aware information to further determine the best quality reception region for the multi-stream broadcast contents.

Description

Description TITLE OF INVENTION: A SYSTEM AND METHOD FOR ADAPTIVE WIRELESS BROADCAST COMMUNICATION Technical Field [0001] The present disclosure generally relates to a method and a system for adaptive wireless broadcast communication. In particular, the present disclosure discloses an optimal range-assisted adaptive wireless broadcast communication. Background Art [0002] Audio broadcast systems are communication platforms that stream audio content to one or more users. These systems capture, encode, and transmit the audio content as a broadcast stream, which is then decoded and played through earbuds, speakers, headphones, radios, televisions, or digital devices. They are commonly used for broadcasting live events, music, news, educational content, and other forms of audio entertainment or information to a broad and diverse audience. [0003] Recently, low-energy (LE) audio broadcast systems that utilize Bluetooth technology have changed the audio experiences of the user and the way the user engages with another user. Such broadcast systems enable the streaming of the broadcast stream wirelessly with improved sound quality while consuming low power. The LE audio broadcast system provides features such as multi-stream audio, hearing aid support, etc. The aforementioned features make it suitable for a wide range of devices such as wireless headphones, wireless earbuds, hearing aids, smart home devices, and the like. [0004] In a multi-stream audio scenario, the LE audio broadcast system typically allows a single transmitting device, such as a smartphone or tablet, to simultaneously stream audio content to multiple receiving devices, such as individual wireless earbuds or headphones. [0005] For example, consider a person using a smartphone to stream music. With the LE audio broadcast system with multi-stream support, the smartphone can simultaneously transmit the audio content to multiple pairs of wireless earbuds or headphones worn by different individuals. This means that several users can listen to the same audio content from a single transmitting device without the need for additional accessories or hardware. [0006] However, the existing audio broadcast systems or the LE audio broadcast system do not consider the quality of reception based on an optimum ranging threshold. Wireless transmission signal has a threshold distance to deliver the best data. When transmissions exceed the threshold distance, the quality is compromised, and users lack control over the quality of reception. [0007] In order to overcome the above problem, the conventional solutions perform hiding certain broadcast contents. However, in such cases the user will potentially never come to know about the nearby wireless broadcasts. While some systems attempt to address this issue by implementing quality feedback reception from a broadcast receiver system, however, it is impossible to receive feedback from an unlimited number of receivers, due to the limitation of the number of dedicated connections supported by any wireless radio system. [0008] Thus, there is a need to provide a methodology to overcome the above- mentioned issues in the conventional techniques. Summary of Invention [0009] This summary is provided to introduce a selection of concepts in a simplified format that are further described in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the invention, nor is it intended for determining the scope of the invention. Solution to Problem [0010] According to an embodiment of the present disclosure, a method for adaptive wireless broadcast communication at a broadcast transmitter. The method includes receiving a user input corresponding to an enablement of an adaptive broadcast mode of the broadcast transmitter. Further, the method includes determining, based on the user input, an optimal quality of Service (QoS) range and a position information of the broadcast transmitter. The method further includes generating one or more correlated broadcast beacon packets embedded with the optimal QoS range, the position information, a broadcast stream identifier, and time synchronization information. Further, the method includes generating one or more assistive beacon batches corresponding to one or more broadcast streams, where each of the one or more assistive beacon batches includes the one or more correlated broadcast beacon packets. The method further includes determining, based on at least one of a total number of active broadcast stream, window length information, and channel map information, at least one of one or more least unused broadcast channels from a plurality of beacon channels, a beacon batch window, a per window beacon density, or a beacon batch chaining interval. Further, the method includes scheduling, the one or more assistive beacon batches based on the one or more least unused broadcast channels, the beacon batch window, the per window beacon densit
