A method for real-time delivery of data based on additive bitrate fragmentation includes receiving a media sample by a server computing device and generating a key frame based on the media sample. The method also includes generating a differential frame based on the media sample and the key frame. The method also includes transmitting a first data packet including the key frame and a second data packet including the differential frame.

Systems and methods for packet dynamic latency estimation for audio streams may include, for example, capturing a first audio signal using a microphone of a computing device; receiving a second audio signal at the computing device via wireless communications from an access point; determining a set of estimates of a delay of the first audio signal relative to the second audio signal based on a cross-correlation at respective analysis steps within the first audio signal and the second audio signal; determining an average delay and a confidence interval for the set of estimates of the delay; comparing the confidence interval to a threshold duration; and, responsive to the confidence interval being less than the threshold duration, playing, using a speaker controlled by the computing device, an audio signal received from the access point with an added delay determined based on the average delay.

A method for embedding provenance data in a user-captured video by a mobile computing device at a live event includes receiving a real-time audio stream including an embedded audio signature key and a secure certificate corresponding to the live event. The method also includes generating geofence verification data based on GPS data of the mobile computing device and GPS coordinates corresponding to the live event. The method also includes generating a master signature key based on the embedded audio signature key, the secure certificate corresponding to the live event, and the generated verification data.

Systems and methods for playing synchronized audio streams for live broadcasts are described. For example, supplemental audio streams (e.g., extra commentary or sound effects) may be streamed over a packet switched network with a copy (e.g., a reduced bandwidth copy) of a main audio signal from a television broadcast. A user device may synchronize the streamed audio with the audio from a television recorded with a microphone, and play a supplemental audio signal synchronously with the audio from the television. For example, methods may include capturing a first audio signal using a microphone; receiving a second audio signal and a third audio signal using a network interface; determining an estimated delay of the first audio signal relative to the second audio signal; and playing, using a speaker, the third audio signal with an added delay determined based on the estimated delay.

Systems and methods for packet payload mapping for robust transmission of data are described. For example, methods may include receiving, using a network interface, packets that each respectively include a primary frame and one or more preceding frames from the sequence of frames of data that are separated from the primary frame in the sequence of frames by a respective multiple of a stride parameter; storing the frames of the packets in a buffer with entries that each hold the primary frame and the one or more preceding frames of a packet; reading a first frame from the buffer as the primary frame from one of the entries; determining that a packet with a primary frame that is a next frame in the sequence has been lost; and, responsive to the determination, reading the next frame from the buffer as a preceding frame from one of the entries.

A method for wireless capture of real-time audio and video at a live event using a mobile computing device includes receiving a data representation of a live audio signal corresponding to the live event via a wireless network.

The method also includes producing, concurrent with the video capture, a shareable video corresponding to the live event based on the captured video and the live audio stream.

Systems and methods for transmitting data partitioned into a sequence of frames may include transmitting a first packet that includes a primary frame and one or more preceding frames from the sequence of frames of data, wherein the one or more preceding frames of the first packet are separated from the primary frame of the first packet in the sequence of frames by respective multiples of a stride parameter; transmitting a second packet that includes a primary frame and one or more preceding frames from the sequence of frames of data, where the primary frame of the first packet is one of the one or more preceding frames of the second packet; and transmitting a third packet that includes a dummy primary frame corresponding to a next sequence index past the last frame of the sequence of frames of data.

A method for real-time generation of live event audience behavioral data includes receiving a data representation of a live audio signal corresponding to the live event via a wireless network and processing the data representation of the live audio signal into a live audio stream. The method also includes calculating a first location of a mobile computing device with respect to a reference point based on first location data. The method also includes generating sensor data based on one or more sensors of the mobile computing device. The method also includes calculating a second location of the mobile computing device with respect to the first location based on second location data. The method also includes determining an audience member behavior based on the sensor data and the second location, and determining a corresponding event based on the live audio stream and a time stamp associated with the audience member behavior.

A method of delivering audio to one or more client computing devices includes receiving, by an audio server computing device, a live audio signal starting at a first time; processing, by the audio server computing device, the live audio signal, thereby creating a data representation of the live audio signal; transmitting, by the audio server computing device, via a wireless network in electronic communication with the audio server computing device, the data representation of the live audio signal to the one or more client computing devices; interpreting, by the one or more client computing devices, the data representation of the live audio signal, thereby producing an interpreted audio signal; and providing, by the one or more client computing devices, the interpreted audio signal to a user listening device starting at a second time. A latency between the first time and the second time is less than 100 milliseconds.
