This application relates to systems and methods for real-time video analysis. A method and a sports analytics system (SAS) for analyzing Live Video Broadcast Streams (LVBS) of sporting events are provided. SAS splits the LVBS into a Real-Time Messaging Protocol (RTMP) stream and a Hypertext Transfer Protocol Live Stream (HLS), and uses the phase difference between the RTMP stream and the HLS to analyze the RTMP stream. SAS uses a first set of cues to detect people present in frames of the RTMP stream and tracks the detected people by analyzing previous frames. SAS uses a second set of cues to identify the tracked people, assigning a separate weight to each of the second set of cues, and comparing the assigned weight of each identified person with pre-existing data of all athletes to identify the athletes in the frames. SAS transmits the contextual interaction content of the HLS and the identified athletes to a user device.

A method and server for producing a live video broadcast from multiple video sources. The server receives a first raw video signal from a first edge device connected to a first video source. The server processes the first raw video signal to generate a broadcast video signal and an ultra-low latency (ULL) video stream, which are transmitted to the video broadcast equipment and user device, respectively. The server receives a command to switch to a second video source and sends a command to begin transmitting a second raw video signal from a second edge device connected to the second video source.
