摘要

The exemplary embodiments relate to devices, systems and methods for a streaming service to provide fast video stream startup at a user device. The streaming service may determine that a video stream for on-demand content is to be provided to the user device and is to include multiple subclips corresponding to the on-demand content and a dynamic content insertion opportunity (DCIO). A first set of multimedia data is transmitted to the user device that corresponds to a first subclip of the on-demand content. When a predetermined condition corresponding to the DCIO is satisfied, a second set of multimedia data is transmitted to the user device that includes multimedia data corresponding to at least the multiple subclips.

說明書

Continuing with the above scenario, there may be instances in which the duration of time between the resume point and the next upcoming DCIO is not enough time for the dynamic content system 224 to fill an DCIO. To account for these edge use cases, in some embodiments, if the resume point is located within a predetermined duration of the upcoming DCIO, the upcoming DCIO may also be excluded from the event playlist. Alternatively, if the user selects a resume point that is located within the predetermined duration, the streaming service 220 may resume the video stream 102 at a point outside of that predetermined duration.

When the event stream is being utilized, the exact duration of the DCIOs is not known because the process of filling the DCIOs has not yet been completed. Consequently, the total playback duration of the video stream 102 is also not known. To provide an adequate user experience at the user device 210, the user interface of the user device 210 may be configured to display the published duration which refers to the total time of the selected program plus the expected duration of the DCIOs 110, 120, 130. When event stream is converted to the VOD stream, the actual duration of the video stream 102 may differ from the published duration. For example, one or more DCIOs may only be partially filled relative to their predetermined duration.
