Abstract: Systems and methods provide live broadcasts with real-time feedback from viewers using mobile computing devices. An example method includes providing a live feed broadcast from a source mobile device to a plurality of viewing devices, receiving, during the live feed broadcast, an engagement from one of the plurality of viewing devices, and associating the engagement with a particular time in the live feed broadcast. The method also includes providing an indication of the engagement to the source mobile device, wherein the source mobile device displays a graphic representation of the engagement during the live feed broadcast and adding the indication of the engagement to the live feed so that a graphic representation is displayed during the live feed at the particular time to users of the plurality of viewing devices. The viewing user may each have a graph relationship with a user of the source mobile device.

Abstract: Implementations provide a structure for low-latency live-video streams using existing content delivery networks. An example method includes creating, at the start of a broadcast stream, a playlist for the broadcast stream that identifies at least two segment files. The content of each of the segment files is a table header. The method also includes transmitting the playlist and each of the segment files to a cache server, obtaining the video broadcast stream as a series of frames, and transmitting each frame in the series of frames to the cache server using an HTTP chunk transfer protocol, each frame being associated with, and written to, a first segment file identified in the playlist. When a frame in the broadcast stream is a break frame, the method includes transmitting an end of file marker for the first segment file and adding a video header for the break frame before it is transmitted.
