Abstract: A streaming video server includes a virtual file system that stores playlist data corresponding to a plurality of video programs available from at least one video source and that stores variant playlist data corresponding to each of the plurality of video programs that indicates a single variant for streaming each of the plurality of video programs. The streaming video server receives a request for a selected one of the plurality of video programs from a client device. The selected one of the plurality of video programs is retrieved from the at least one video source in response to the request. A rate generator generates rate data based on the transmission feedback data. A plurality of encoded segments are generated from the selected one of the plurality of video programs, based on rate data.

Abstract: A streaming video server includes a virtual file system that stores playlist data corresponding to a plurality of video programs available from at least one video source and that stores at least one initial video program segment for each of the plurality of video segments. The streaming video server receives a request for a selected one of the plurality of video programs from a client device. The selected one of the plurality of video programs is retrieved from the at least one video source in response to the request. A plurality of encoded segments are generated from the selected one of the plurality of video programs, based on rate data. A multiplexer generates a plurality of output segments from the at least one initial video program segment corresponding to the selected one of the plurality of video programs and the plurality of encoded video program segments.

Abstract: A client device includes a video player that generates a program request for a selected video program. A client-side proxy passes the program request from the video player to the streaming video server for the video program. The client-side proxy identifies that the selected video program has been previously bookmarked by the video player at a bookmark position, intercepts a request from the video player to the streaming video server for at least one first segment of the selected video program, and in response, sending at least one corresponding fixed segment to the video player. The client-side proxy passes a request from the video player to the streaming video server for a plurality of second segments of the selected video program, wherein the plurality of second segments commence at a position corresponding to the bookmark position.

Abstract: A client device includes a client-side proxy that is operable to receive server playlist data corresponding to the selected one of the plurality of video programs, to generate proxy playlist data corresponding to the selected one of the plurality of video programs based on the server playlist data and to send the proxy playlist data to the video player. In particular, the client-side proxy generates the proxy playlist data by translating the server playlist data from a first playlist format, such as a sliding window format of the HLS protocol, to a second playlist format, such as an event playlist format.

Abstract: A streaming server includes a command handler that is operable to receive a request for a selected video program from the client device that has been previously bookmarked by the client device at a bookmark position. The command handler sends an event playlist to the client device having a plurality of event playlist segments including a last segment that is based on the bookmark position. The command handler receives a request for the last segment of the plurality of event playlist segments from the client device and sends the last segment of the plurality of event playlist segments to the client device. The command handler sends a full playlist to the client device after sending the last segment of the plurality of event playlist segments to the client device.
