With the increased availability of residential broadband delivery of digital video content and the ever-growing number and variety of digital video content sources, consumers are storing more content than ever on digital video recorders (“DVRs”). Many residences may even have multiple DVRs to meet the demands for content storage within a given household. These devices, often integrated into set-top boxes, offer consumers a convenient means of capturing one or more live streams of digital content for later and/or repeated viewing.
Unfortunately, the advent of an ever-increasing amount of certain playback conditions can cause a DVR to deliver an inconsistent or disjointed viewing experience to a user. One particular inconsistency typically occurs when a user that was viewing a recorded portion of a program that is still being broadcast or streamed. Assume that the program being viewed has a duration of one hour and began streaming to the DVR at time to. The user accesses the DVR at some time after to, but prior to the end of the streaming of the program, and begins consuming the recorded portion of the program. Then, by utilizing fast-forward or other trick-play functionality, the user advances to the terminus of the recorded content. At this juncture, the DVR would need to switch to the live streaming content to continue the user's viewing experience in a continuous manner.
However, achieving a seamless switch to the incoming stream of video is not something that can be accomplished with present DVR technology. There is a discontinuity manifested as a delay or break in the viewed content introduced by the need for the DVR system to reload the media presentation description (“MPD”) file that defines and enables the connection to the incoming streamed content. This reloading/connection process invariably introduces a delay resulting in an inconsistent viewing experience. The DVR might also be adapted to simply wait for the next available segment of the incoming stream to be received and then access it. However, this too would involve a delay which would invariably cause an inconsistency in the viewed program.
Consequently, there exists a need for a system and method supporting an improved process that provides improved continuity when transitioning between the viewing of a recorded program portion and the viewing of the streaming remainder of that program.
A system and method enabling the seamless transition between viewing a recorded portion of a program and rejoining a live stream of that program. The system and method enable the rapid provision of live-streamed content upon the exhaustion of the playback of recorded content. This achieved by utilizing a universal resource locator associated with the source of the content.
The aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings in which:
MGA 102 is shown to include controller 112 and memory 114 which are adapted to provide DVR functionality. As is typical for a DVR, incoming streaming video received via broadband network 106 is stored within memory 114, enabling a user to view the recorded content upon display 108 as desired. Controller 112 is adapted to create a hybrid MPD (“HMPD”) that includes a universal resource locator (“URL”) for the CDN providing the program being recorded.
If the conditional at step 308 yields a negative result, the test simply loops back and the query is repeated until a positive result is obtained, or the streaming of content C1 has terminated (steps 310 and 318). If, however, conditional 308 yields an affirmative result, the system retrieves the URL associated with the streaming of content C1 (step 312) and establishes a connection thereto (step 316) via broadband network 106 (
The ability of the disclosed process to readily access the live stream associated with the recorded content enables the system to switch to that live feed very quickly. There is no delay introduced by the need to reload content or await the storage of the next segment of incoming content. The result is a smoother transition from recorded content to streaming content, providing a user with a viewing experience that appears seamless.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. Other embodiments and variations could be implemented without departing from the spirit and scope of the present invention as defined by the appended claims. For example, the depiction of the HMPD is not meant to be exhaustive. Other data fields, not critical to the delivery of a seamless video transition, could be included in accordance with various standards and particular system and network requirements. In addition, it will be understood that the various connections depicted as wired in the above embodiments could also be supported by wireless connections without departing from the scope of the invention. The controller can be a single or multiple multi-processor system, co-located with the memory or remotely based in whole or in part. The memory supporting the storage of the video content can be a disk, a solid-state drive, cloud-based storage (in whole or in part), or any other means with sufficient capacity and speed to facilitate video storage and playback. Similarly, any number of various video-capable devices could serve as the display. These include digital televisions, tablets, smart phones, computer monitors, etc.
