  • Publication number: 20220303326
    Abstract: The present invention extends to methods, systems, and computer program products for converting an RTSP coordinated stream into an HLS stream. A server participates essentially simultaneously in an RTSP coordinated stream with a content creating electronic device (e.g., a camera) and in an HLS stream with the end-point (e.g., a Web browser). The media server receives a portion of RTSP stream data directly from the content creating electronic device. The media streaming server converts the portion of RTSP stream data into HLS stream data. The media streaming server sends the HLS stream data via the HLS stream to the end-point. The end-point or an end-point user may subsequently request termination of content streaming. In response to an HLS terminate instruction, the streaming media server can coordinate (e.g., concurrent) termination of both the RTSP coordinated stream and the HLS stream.
