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

To provide an example of 335, if the entirety of the subclip 140 was provided to the user device 210 in 320, in 335, multimedia data corresponding to at least the DCIO 110, subclip 150, DCIO 120, subclip 160, DCIO 130 and subclip 170 may be transmitted to the user device 210. To provide another example, if 5 seconds of the subclip 140 was provided to the user device 210 in 320, in 335, multimedia data corresponding to at least the remaining portion of subclip 140, DCIO 110, subclip 150, DCIO 120, subclip 160, DCIO 130 and subclip 170 may be transmitted to the user device 210.

In some embodiments, the multimedia data transmitted in 335 may also include the first set of multimedia data transmitted in 320 (and any multimedia data transmitted in 325). This may be done to ensure that transport controls (rewind, pause, fast forward, etc.) can be used at the user device 210 on the video stream 102. In other embodiments, the multimedia data transmitted in 330 may not include the multimedia data transmitted in 320. Instead, the user device 210 may combine the multimedia data transmitted in 335 with the first set of multimedia data transmitted in 320 (and any multimedia data transmitted in 325).
