System for managing video playback using a server generated manifest/playlist

Abstract

An apparatus and method for managing video playback for users during video streaming is disclosed. In one aspect, the method may include receiving a request from a first video player for playing a video stream, identifying a first playlist for the video stream, modifying the first playlist for the video stream to produce a second playlist identifying a first combination of video content segments and alternative content segments, transmitting the second playlist to the first video player to allow the first video player to provide playback of video content comprising the first combination of the video content segments and the alternative content segments, receiving, from the first video player, an indication of a request of a user of the first video player to seek forward when viewing the video content, modifying the second playlist for the video stream to produce a third playlist identifying a second combination of video content segments and alternative content segments, and transmitting the third playlist to the first video player, the third playlist indicating whether the request of the user to seek forward is allowed.

Description

BACKGROUND

The subject matter disclosed herein relates to a method for managing video playback for users during video streaming. More specifically, a method and apparatus for using a server to generate per-user manifest file updates for controlling video playback is disclosed.

Video streaming allows video content to be delivered to a video player via the internet. The video content is a video signal generated by a content provider for distribution to video consumers. The video signal may be provided in an uncompressed file format, such as a serial digital interface (SDI) format, or in a compressed format, such as a Moving Picture Experts Group (MPEG) file format or Transport Stream (TS) file format. The video signal is sent to an encoder which converts the file into a live streaming signal. The live streaming signal is preferably a segmented data stream that may be transmitted using standard Hypertext Transport Protocol (HTTP) over the internet. The live streaming signal may include multiple streams, where each stream may have a different data rate and/or different resolution.

Two common formats for the live streaming signal include HTTP Live Streaming (HLS) implemented by Apple® and MPEG-Dynamic Adaptive bitrate Streaming over HTTP (MPEG-DASH) implemented, for example, by web browsers such as Chrome®, Microsoft Edge®, and Firefox®. In addition to the segmented data stream, the encoder generates a manifest file. The manifest file contains information for a video player to play the segmented data stream such as the data rate and resolution of each stream and a playlist providing an address from which the video content may be retrieved. Historically, the encoder has generated a single manifest file for each encoded video signal, where the manifest file is distributed along with the streaming signal.

The live streaming signal and the manifest file are stored in one or more Content Delivery Networks (CDN). Each CDN includes a number of edge servers which store the streaming signal and manifest file until requested by a video player. When the streaming signal is provided to multiple CDNs, the CDNs may be in different geographic locations, such as the West Coast, East Coast, or Midwest. Each video player may select a CDN based, among other things, on its geographic proximity in order to reduce transmission latencies.

The video player may be any suitable electronic device to receive the streaming signal such as a desktop computer, a television, a laptop computer, a tablet, or a mobile phone. A user initiates a request to view desired video content on the video player. The video player includes video management software executing on the video player which has knowledge of the address of the CDN and which may provide a list of video content stored on the CDN to the user. After the user has selected a desired video, the video player, in turn, requests that the video content be transmitted from the CDN.

As is further known to those skilled in the art, it is often desirable to enforce logic rules for distribution of video content which may impact a user's experience. For example, it may be desirable to allow a user to view requested video content for a predetermined amount of time, such as 120 seconds, before then being required to view advertising or other alternative content. Also, it may be desirable to inhibit a user's ability to skip such alternative content if the user has already viewed a predetermined amount of the requested video content, or conversely, allow the user to skip the alternative content if the user has not viewed the predetermined amount of requested video content. Also, it may be desirable to allow a user to skip the alternative content if the user is seeking to go back and replay a previously viewed portion of the requested video content.

However, these logic rules for distribution of video content can be complex to implement and enforce, particularly given the variety of possible configurations that exist for video players. As a result, there is a need to improve the implementation of such logic rules across the widest variety of video players possible.

BRIEF DESCRIPTION OF THE DISCLOSURE

The subject matter disclosed herein describes an apparatus and method for managing video playback for users during video streaming. In one aspect, a server may be used to generate manifest files and updates to video players requesting video content. As a result, instead of relying on each video player to enforce logic rules for distribution of the video content, the manifest files and updates may be used to enforce the logic rules on a wider variety of video player configurations. In addition, the manifest files and updates may be provided unique to each video player. Consequently, the manifest files and updates may further provide customized user experiences despite the same video content being requested.

According to one embodiment of the present disclosure a system for managing video playback is disclosed. The system includes a manifest server configured to communicate with a video player and a content delivery network. The manifest server executes a program stored in a non-transient medium to receive a request from a video player for playing a video stream. Upon receiving the request, the manifest server communicates with a content delivery network to obtain a first manifest file containing information for allowing a video player to play the video stream. The manifest server modifies the first manifest file to produce a second manifest file unique to the video player having the request, where the second manifest file contains information for allowing the video player to play the video stream according to a rule that is added to the second manifest file.

According to other aspects of the disclosure, the rule may direct the video player to play alternative content in addition to playing the video stream. Optionally, the rule may direct the video player to play the alternative content before playing the video stream or the rule may direct the video player to play the alternative content after playing a predetermined amount of the video stream. According to still another option, the rule may inhibit the video player from skipping the alternative content.

According to still other aspects of the disclosure, the second manifest file may include a session identifier for identifying a connection between the manifest server and the video player having the request. The method may include modifying the second manifest file to produce an updated second manifest file unique to the video player having the request, where the updated second manifest file contains information for allowing the video player to play the video stream according to the rule and a second request from the video player. The second request may be to seek forward or backward in the video stream, and the manifest server may compare the second request to a view history of the video player to produce the updated second manifest file.

According to another embodiment of the disclosure, a method for managing video playback using a manifest server configured to communicate with a video player and a content delivery network is disclosed. The method receives a request from a video player for playing a video stream and upon receiving the request, communicates with a content delivery network to obtain a first manifest file containing information for allowing a video player to play the video stream. The first manifest file is modified to produce a second manifest file unique to the video player having the request, where the second manifest file contains information for allowing the video player to play the video stream according to a rule that is added to the second manifest file.

These and other objects, advantages, and features of the disclosure will become apparent to those skilled in the art from the detailed description and the accompanying drawings. It should be understood, however, that the detailed description and accompanying drawings, while indicating various embodiments of the present disclosure, are given by way of illustration and not of limitation.

DETAILED DESCRIPTION OF THE DISCLOSURE

The various features and advantageous details of the subject matter disclosed herein are explained more fully with reference to the non-limiting embodiments described in detail in the following description.

Turning initially to FIG. 1, one environment for managing video playback using manifest files generated by a server is illustrated. A content provider 110 generates a video signal 112 to be distributed to video consumers. The video signal may be provided in an uncompressed file format, such as a SDI format, or in a compressed format, such as an MPEG or TS file format. The video signal 112 is sent to an encoder 114 which converts the file into a live streaming signal 116. The live streaming signal 116 is preferably a segmented data stream that may be transmitted using standard HTTP or HTTPS protocol over the internet. The live streaming signal 116 may include multiple streams, where each stream may have a different data rate and/or different resolution. The format of the live streaming signal may be, but is not limited to, HLS or MPEG-DASH. Still other protocols such as HTTP Dynamic Streaming (HDS) from Adobe® or Microsoft® Smooth Streaming and the like may be used without deviating from the scope of the disclosure.

In addition to the segmented data stream, the encoder generates a manifest file. The manifest file contains information for a video player 122 to play the segmented data stream such as the data rate and resolution of each stream and a playlist providing an address from which the video content may be retrieved. The encoder 114 generates a single manifest file for each encoded video signal, where the manifest file is distributed along with the streaming signal 116 and stored on a CDN 118. Each CDN 118 includes a number of edge servers 120 which store the encoded video signal 116 and manifest file until playback of the video content is requested by a video player 122. Although the embodiment illustrated in FIG. 1 shows a single CDN 118, it is contemplated that the encoded video signal 116 may be stored on multiple CDNs 118. The manifest file may include an address of each CDN such that playback may occur from any of the CDNs 118.

As further shown in FIG. 1, the illustrated environment includes a manifest server 124. The manifest server 124 is used to provide a unique manifest file, also referred to herein as a per-user manifest file, to each video player 122 for each requested video content. Each video player 122 includes a native video player module 128 which provides an interface to a user and which manages video playback on the video player 122. Some video players 122 may further include an enhanced video player module 129, illustrated as an optional module in FIG. 1. The enhanced video player module 129 may be a plug-in or other software module executing on the video player 122 that either complements (i.e., adds additional capabilities) or replaces (i.e., adds additional capabilities and incorporates the video interface and playback capabilities) the native video player module 128. As will be discussed in more detail below, when a user 125 requests video content for playback on the video player 122, the native or enhanced video player module 129 communicates with the manifest server 124 rather than the CDN 118 to obtain the manifest files for video playback. The manifest server 124 manages the retrieval and delivery of the manifest file generated by the encoder 114 to provide the unique manifest file to each video player 122.

Turning next to FIG. 2, the operations performed to manage video playback using manifest files generated by a server are illustrated. At block 130, the encoder 114 receives the initial video signal 112. It is contemplated that this video signal 112 may be a pre-recorded signal, such as an episode of a television show or a movie, or the video signal 112 may be a live stream, for example, of a sporting event, concert, or news feed. The encoder 114 converts the original video signal into a live streaming signal 116 suitable for delivery via HTTP or HTTPS. One operation in converting the video signal is to divide the video signal into segments. The segments may be, for example, 10 seconds in length. Optionally, other segment lengths, for example, from 1 second up to 10 seconds may be selected. The length of the video segment must be less than the maximum payload for an HTTP data packet. Referring briefly to FIG. 3A, a video signal 116 from the encoder 114, shown by way of example, may consist of video content being divided into nine segments of requested video content, illustrated as “c1,” “c2,” “c3,” and so forth, with each segment being 10 seconds in length for a net content length of 90 seconds. After generating the video signal 116 into segments (also referred to as requested video content), the video signal and a manifest file are transmitted to the CDN 118 for storage in one of the edge servers 120, as shown in block 132.

At block 134, a user 125 then requests playback of a desired video segment on the video player 122. The video player 122 may be any suitable electronic device to receive the streaming signal 116 such as a desktop computer, a television, a laptop computer, a tablet, Wi-Fi enabled device connected to a video screen, or a mobile phone. At block 136, the video player 122, in turn, requests a manifest file from the manifest server 124 in order to retrieve the information necessary to play the requested video content. With reference also to FIGS. 4 and 5, segments of manifest files are illustrated that demonstrate a portion of the content that may be available in a manifest file. The manifest file is a text file and the particular content on each line of the text file is identified by the directive at the start of the line. For example, FIG. 4 identifies four different streams in the streaming signal 116 where each stream has a different bandwidth. The location of a playlist for each of the streams is also included in the manifest file. FIG. 5 is another manifest file which contains a portion of the playlist of an encrypted video segment. Each line may identify a particular video segment between 1 and 5 (i.e., the “−1”, “−2”, etc . . . prior to the .ts file extension), and provides the location of video segment in the CDN 118. The manifest file may include any information corresponding to the video stream, such as metadata information for the video stream.

When the video player 122 requests the manifest file from the manifest server 124 a connection is established between the devices. A session identifier is also generated to identify the connection. The session identifier may be generated by the video player 122 or the manifest server 124. For purposes of illustration, it will be assumed that the session identifier is generated by the video player 122. The session identifier is transmitted to the manifest server 124 by the video player 122 when requesting a manifest file. The manifest server 124 then requests the manifest file from the CDN 118 at block 138. At block 140, the CDN 118 returns the manifest file to the manifest server 124.

Because the manifest server 124 has established a connection with video player 122, it may customize the manifest file prior to returning the manifest file to the video player 122 and provide a unique manifest file to each video player 122. Without the manifest server 124, the video player 122 retrieves the manifest file directly from the CDN 118 and the content of the manifest file is the same for all users. However, because the manifest server 124 is providing a unique manifest file to each player, the manifest file may include identifying information of the video player 122, the user 125 of the video player, or a combination thereof. Further, the manifest file may be modified to include content specific for the user 125.

According to one embodiment of the disclosure, the manifest server 124 is configured to generate a unique per-user manifest file (and updates) for the video player 122. The manifest file from the manifest server 124 may reflect logic rules which may be desirable to enforce for distribution of the video content to the user 125. For example, a video manifest file may be modified by the manifest server 124 to enforce logic rules requiring viewing alternative content, such as commercial advertisements, at the video player 122 at a very start of the streaming signal 116, or logic rules requiring inhibiting an ability of the user 125 to skip such alternative content if the user 125 has already viewed a predetermined amount of the streaming signal 116, or conversely, logic rules allowing the user 125 to skip the alternative content if the user 125 has not viewed the predetermined amount of the streaming signal 116. Accordingly, the manifest server 124 may generate a customized manifest file for the video player 122 which stitches together requested video content and alternative content into a single video stream according to predetermined logic rules desired to be enforced.

For example, referring briefly to FIG. 3B, with the customized manifest server generated, the video signal 116 may be reconfigured for playback as a modified video signal 116′ including two segments of alternative content, illustrated as “a1” and “a2, followed by four segments of requested video content, illustrated as “c1,” “c2, “c3” and “c4, followed by another two segments of alternative content, illustrated as “a2” and “a3, and followed by another four segments of requested video content, illustrated as “c5,” “c6, “c7” and “c8.” With segments being 10 seconds in length, the modified video signal 116′ may then have a gross content length of 130 seconds. This stitched video stream may reflect, for example, enforcement of a logic rule by the manifest server 124 requiring initial viewing of a first advertisement and a midstream viewing of a second advertisement for a first time viewing of the requested video content at the video player 122. Each time the user 125 plays a video, the video player 122 may obtain an updated manifest file from the manifest server 124. The manifest server 124 may individually track a status of the video player 122 and the user view experiences. At block 142, the manifest server 124 transmits the manifest file to the video player 122.

Referring again to FIG. 1, if the video player 122 includes an enhanced video player module 129 from the provider of the manifest server 124, the enhanced video player module 129 may be configured to store the view history of the user 125 on the video player 122 for providing to the manifest server 124. The enhanced video player module 129 may store and provide, for example, which alternative content the user 125 has viewed, total content time the user 125 has viewed, total alternative content time the user 125 has viewed, a listing of the requested content and alternative content the user 125 has viewed by segment, and so forth. If the video player 122 does not have an enhanced video player module 129, then the manifest server 124 may seek to record such view history directly.

The manifest server 124 may use the view history to enforce logic rules for each video player. For example, logic rules may require a first amount of alternative content, such as advertisement, be viewed by users at a first subscription level and may require a second amount of alternative content be viewed by users at a second subscription level. When the video player 122 establishes a connection with the manifest server 124, the appropriate logic rules for the connection are determined based, for example, on a user name or device identification provided from the video player to the manifest server. The video player 122 is unable to distinguish between alternative content and the requested content based on the playlist provided in the manifest file. Therefore, the manifest server updates the playlist in the manifest file to enforce the logic rules associated with each connection.

Having received the manifest file from the manifest server 124, at block 144, either the enhanced video player module 129 or the native video player module 128 executes the modified video signal 116′ in a single video stream. The manifest file will have the address of the CDN 118 as containing the segmented video content. Therefore, the video player 122 can start retrieving the video content from the CDN. The video player 122 repeatedly requests the next segment in the playlist from the CDN 118 and the CDN 118 returns the requested segment according to the modified video signal 116′.

Referring again to FIG. 2, according to another aspect of the disclosure, at block 146, the user 125 may wish to seek forward or backward when viewing the modified video signal 116′, such as to view a specific requested video content segment or to skip viewing alternative content stitched into the playlist. Accordingly, instead of the video player 122 seeking forward or backward to a requested video content segment in accordance with the user's request, at block 148, the video player 122 redirects the user's request to the manifest server 124. The manifest server 124, in turn, may consider the logic rules to be enforced based on the requested video content and/or the view history on the video player 122. At block 150, the manifest server 124 may deliver an updated manifest file to the video player 122 responsive to the user's request while within the limits of the logic rules to be enforced. Then, at block 152, either the enhanced video player module 129 or the native video player module 128 proceeds to execute according to the updated manifest file in a single video stream via the CDN 118.

For example, referring briefly to FIGS. 3A-3C, the user has requested the video signal 116 for playback on the video player 122. The logic rules in the manifest server 124 may require the alternative content, such as commercial advertising, a1-a4 be inserted within the video stream provided to the video player 122. The video player 122, therefore, receives a custom manifest file with a playlist for a modified video signal 116′ including a1, a2, a3, and a4 inserted. At the beginning of the playback of the modified video stream 116′, the user may try to skip a portion or all of the commercial advertisements (a1, a2) by initiating a seek forward request on the video player 122. The enhanced video player module 129 redirects the seek forward request to the manifest server 124. Upon the video player 122 redirecting a user's request to seek forward or backward in the modified video signal 116′, for example, to video content segment “c6,” the manifest server 124 may consider the logic rules and/or view history on the video player 122 associated with the particular connection. If the user has satisfied the required rules for viewing alternative content, the manifest file returns a playlist starting at segment “c6” and allows the user to continue viewing from segment “c6”. If, however, the user has not satisfied the logic rules, the manifest server 124 provides a manifest file including alternative content, such as a3 and a4 prior to viewing “c6”. The video player 122 then begins playback of the new alternative content requiring the user 125 to view alternative content before viewing the video content segment “c6.” As a result, the manifest server 124 delivers a second modified video signal 116″ (i.e., an updated playlist in a manifest file) to the video player 122 responsive to the user's request, but enforcing a logic rule, and thereby requiring the user 125 to first view two segments of alternative content, illustrated as “a3” and “a4,” before viewing the sought content segment “c6.”

Optionally, the manifest server 124 may enforce logic rules by inhibiting seek operations. For example, if the logic rules require viewing of two alternative content segments (e.g., a1, a2) prior to viewing requested video content, the initial playlist in the manifest file may add the two alternative content segments at the beginning as shown in the modified video stream 116′. If a user initiates a seek forward operation, the enhanced video player module 129 again transmits the request to the manifest server 124. The manifest server 124 may discard or ignore the seek forward operation until the view history indicated that the required alternative content has been viewed. It is, therefore, one aspect of the disclosure that a server-side assisted method may be used to enforce logic rules for video view experiences by enforcing such rules in video manifest files delivered to video players. Individual video manifest files may be updated to enforce such rules unique to each video player as desired.

According to another aspect of the disclosure, the manifest server 124 may record a user's viewing history from multiple devices to enforce the logic rules. For example, a user may begin watching a requested video stream 116 on a first video player 122. The manifest server 124 generates the per-user manifest file including a playlist for the modified video stream 116′ according to the logic rules associated with the user. The manifest server 124 records the view history from the first video player 122 associated with the user and the requested video stream 116. The user may stop viewing the video stream 116 on the first device and later resume watching the video stream 116 on a second video player 122. If both video players are associated with the user, the manifest server 124 has the view history of the user stored and may begin playback on the second video player 122 according to the logic rules and the prior viewing history. Thus, a server-side assisted device hand over may allow hand over video status and/or user status information from one device to another device. When a user hands over video playback from one device to another device, such as from a smart phone to a television, the viewing history and associated user experiences may transfer to the other device.

In one aspect of the disclosure, a server-side assisted method may be used to enforce logic rules for video view experiences by enforcing such rules in video manifest files delivered to video players. Individual video manifest files may be updated to enforce such rules unique to each video player as desired.

According to another aspect of the disclosure, a video manifest file may be modified by a server to include video segments which video viewing logic rules dictate. For example, logic rules may dictate modifying the manifest file to insert alternative content, such as commercial advertisements, at a very start of the video stream. Each time a user plays a video, the video player may obtain an updated manifest file from the server. The server may individually track the status of video players and their user view experiences, such as for how much time a current video may have been played by a user, among other things.

According to another aspect of the disclosure, video seek operations may be performed per-user via a manifest file delivery service provided by a server which returns manifest files to users enforcing logic rules which do not allow skipping of alternative content. As a result, if a user seeks to advance forward or backward in video stream, instead of the video player seeking forward or backward, the video player may request a manifest file update from the server.

According to another aspect of the disclosure, a software layer may be provided for the video player to provide, among other things, video content length, current play position, and location of alternative content, when a corresponding manifest file does not contain one or more of such segments. This may hide complexity in total length computations and accurate seek position determinations in the event that a manifest file contains only partial segments. In one aspect, content length may include strictly requested video content and not alternative content.

According to another aspect of the disclosure, a server side assisted device hand over may be provided to hand over video status and/or user status information from one device to another device. A per-user device manipulator may keep track of user status and/or video status, and when a user hands over video streaming from one device to another device, such as from a smart phone to a media player connected to a television, all user experiences may also transfer to the other device.

Portions of the disclosed embodiment are described herein as being implemented on various physical devices, including, but not limited to the video player 122, the manifest server 124, the encoder 114, or the edge server 120 within a CDN 118. It would be understood by one skilled in the art that these devices may include processing devices, such as a single microprocessor, multiple microprocessors, co-processors, application specific integrated circuits (ASICs), or multiple computing devices operating separately, in tandem, or a combination thereof.
