Description

UPDATING MULTIMEDIA CONTENT

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial Number 63/079,327 filed September 16, 2020; this application claims priority to India patent application serial number 202031032816 filed July 30, 2020.

BACKGROUND

[0002] The subject matter of this application relates to the update of multimedia content, in particular systems and methods to update multimedia content that is recorded on a digital video recorder or a network digital video recorder, and/or stored in one or more content servers and/or over-the-top servers.

[0003] Users may record various multimedia content on a digital video recorder (DVR) or a network digital video recorder (nDVR) and then view the recorded content from those recorder(s). Additionally, users may view various multimedia content from over-the-top (OTT) servers. Updated versions of the multimedia content may be created and/or produced to include additional and/or different components from the previous version(s). For example, some previous versions of live events may be truncated to fit duration requirements. Updated versions of those live events may be longer in duration to include coverage of the entire events. Alternatively, previous versions of live events may be truncated or shortened to remove, for example, one or more advertisement breaks. Additionally, updated versions of multimedia content may include new or different subtitles and/or caption text, new or different audio language(s), new or different quality or resolution (e.g., standard definition, high definition, or ultra-high definition, or 4K ultra-high definition), three-dimensional (3D) versions, new or different content portions (e.g., deleted scenes, additional/bonus scenes, bloopers, director’s cut, alternative view(s) and/or angle(s)), etc. However, after the multimedia content is stored and/or viewed from the DVR, nDVR, and/or OTT server(s), users are not made aware of updated versions of the multimedia content.

[0004] What is desired, therefore, are systems and/or methods of updating multimedia content that includes monitoring for updated versions of the multimedia content stored and/or viewed from the DVR, nDVR, and/or OTT server(s), alerting the users of those updated versions, and/or storing those updated versions.

DETAILED DESCRIPTION

[0010] Referring to FIG. 1, an example network environment 100 for providing content from a content network 102 to a home or user network 104 via a provider, access, or subscriber network 106, and for facilitating the update of multimedia content provided from the content network to the home or user network via the subscriber network. Content includes any type of video or audio media, such as movies, television shows, music, radio, etc.

[0011] Content network 102 includes one or more content servers 108 and one or more over-the-top servers 110. The content and over-the-top servers store content that is provided to home network 104. Content server(s) 108 provide content via a multiple system operator (MSO) and/or an internet service provider. Over-the-top servers (OTT) 110 provide content only via over the top streaming for at least one client device of the home network.

[0012] Subscriber network 106 includes one or more Multiple System Operator (MSO) systems 112, which includes multiple cable TV systems and/or direct satellite TV systems. For example, MSO system 112 may include one or more headends, regional headends, a network architecture of fiber optic, twisted pair, and/or co-axial lines, and/or amplifiers. In some embodiments, one or more MSO systems 112 include a content monitoring component or apparatus 113, which includes software, hardware, and/or firmware capable of monitoring content from content network 102. Subscriber network 112 also includes one or more Internet Service Providers (ISP) 114. Each ISP 114 includes a Point of Presence (POP) that connect to Network Access Points (NAP), such as via routers and a T3 backbone. In the example shown in FIG. 1, subscriber network 106 includes one or more network Digital Video Recorders (nDVRs) 116, which may be part of and/or separate from MSO systems 112. In some embodiments, one or more nDVRs 116 include a content monitoring component or apparatus 117, which includes software, hardware, and/or firmware capable of monitoring content from content network 102. Various content from content network 102 may be recorded and/or stored on nDVRs 116 based on requests made by users or subscribers. Subscriber network 106 may include other components not explicitly shown in FIG. 1, such as transcoders, streamers, just-in- time (JIT) packagers, etc. [0013] Home/user network 104 includes a gateway 118, a set top box 120, user devices 122, and an Internet Protocol (IP) set top box 124. Set top box 120 is operable to connect to a television to deliver television services through traditional terrestrial, satellite, and cable formats. Set top box 120 may have a graphic user interface (GUI) that may be assessed by the user via the television to which set top box 120 is connected. User devices 122 may be any device that may receive content, such as smart phones, mobile phones, tablet computers, smart watches and other wearables, gaming systems, etc. The user devices may have a GUI that may be accessed by the user via the screen on the device. IP set top box 124 is operable to connect to a television over the Internet instead of being delivered through traditional terrestrial, satellite, and cable formats. The IP set top box may have a GUI that may be accessed by the user via the television to which the IP set top box is connected.

[0014] Home/user network 104 also includes a first digital video recorder 126, which may be part or a component of set top box 120 as shown in FIG. 1 or may be a separate and distinct device from set top box 120. Additionally, home/user network 104 includes a second digital video recorder 128, which may be part or a component of IP set top box 124 as shown in FIG. 1 or may be a separate and distinct device from IP set top box 124. The first and second digital video recorders may collectively be referred to as “local digital video recorders” as they are generally physically located within the user’s home or premises.

[0015] Referring to FIG. 2, a flowchart is shown of an example method or process 200 of automatically updating stored content, which may be performed, for example, by network digital video recorder 116, local digital video recorders 126, 128, and/or content monitoring components 113 and/or 117. At 202, an updated version of content that is stored on a local digital video recorder (DVR) or a network digital video recorder (nDVR) is monitored. In other words, monitoring is performed to check for the availability of one or more updated versions of the content that is stored on a DVR or a nDVR. [0016] Monitoring may be performed automatically without user action or intervention, and/or may be performed in response to user action or request. In some embodiments, there may be historical data regarding user’s desired properties for updated versions of content, such as updated versions of content that was previously stored on a DVR or nDVR. Desired properties for updated versions of content may include one or more desired languages for subtitles and/or caption text, one or more desired audio language(s), one or more desired quality or resolution (e.g., standard definition, high definition, or ultra-high definition, or 4K ultra-high definition), one or more desired versions (e.g., three-dimensional (3D) versions), one or more desired content portions (e.g., deleted scenes, additional/bonus scenes, bloopers, director’s cut, alternative view(s) and/or angle(s)), etc. In some embodiments, the desired properties may be classified by relevance, such as “critical/important” and “good/ nice to have.”

[0017] In some embodiments, monitoring may be performed automatically when the stored content does not include one or more (or most or all) of the user’s desired properties based on the historical data. For example, historical data regarding user’s desired properties may include data indicating that the user typically desires movies with French language subtitles and/or audio, ultra-high or 4K ultra-high definition versions, and three-dimensional versions. When a new movie is stored on the DVR or nDVR, monitoring for an updated version of that movie may be initiated automatically (without user request or intervention) when the movie stored on the DVR or nDVR does not include French language subtitles and/or audio, ultra-high or 4K ultra-high definition, and/or a three-dimensional version. When the user’s desired properties are classified or ranked by importance, the monitoring may be performed automatically when, for example, the stored content does not include one or more (or most or all) of the desired properties that were historically important or critical in previous updated versions.

[0018] At 204, an updated version of the stored content is detected. The detection may be for any updated version of the stored content and may be performed in any suitable ways. For example, in some embodiments, the number of packet identifiers in the content stored on the DVR or nDVR are identified. Detecting an updated version of content includes detecting a version that includes more packet identifiers than the content that is stored on the DVR or the nDVR. Additionally, in some embodiments, detecting an updated version includes determining components of program map table(s) and/or other intrinsic transport stream parameter(s) of the content that is stored on a DVR or a nDVR and identifying one or more updated versions that includes more components in its program map table(s) and/or other transport stream(s) as compared to the program map table(s) and/or other transport stream(s) of the content that is stored on a DVR or a nDVR. In some embodiments, any suitable combination of the above methods may be used for detecting.

[0019] In some embodiments, the detection may be only for updated versions of the stored content that includes one or more desired properties or all of the desired properties. In those embodiments, method 200 may include determining whether or not an updated version has any, some, or all of the desired properties. In other words, the detection step may be limited to detecting updated versions that include one or more desired properties, most of the desired properties, or all of the desired properties. When the desired properties are classified or ranked, the detection may, in some embodiments, be limited to one or more, most, or all of the critical or important desired properties. The desired properties may be from user input for those particular updated versions. Alternatively, or additionally, the desired properties may be from historical user data, such as historical user data from updated versions of content that was previously stored on the DVR or the nDVR.

[0020] At 206, the updated version of the content is stored on the DVR or the nDVR. In some embodiments, storing includes scheduling recording of the updated version on the DVR or the nDVR, such as when the updated version is not yet available. In some embodiments, the storing step includes deleting the previous version of the stored content and/or replacing the previous version (or previously stored version) with the updated version. In some embodiments, storing is only performed when the updated version includes one or more, some, or all of the desired properties (when input is received from the user or when based on historical data of desired properties).

[0021] Method 200 may, in some embodiments, include, at 208, receiving input from a user regarding which of the content that is stored in the DVR or the nDVR and associated with the user should be monitored for an updated version. In some embodiments, the user input may include one or more desired properties for the updated version of the content, such as the desired properties previously described. Additionally, the user may classify or rank one or more of those desired properties. The user may, for example, be prompted and/or provided with a graphical user interface (GUI) of the set top box or IP set top box to select which of the content stored on the DVR or the DVR should be monitored for an updated version, select the desired property(ies) of the updated version(s), and/or classify or rank the selected desired property(ies).

[0022] Method 200 may, in some embodiments, include, at 210, alerting the user of the stored updated version on the DVR or the nDVR, such as when the previous version stored on the DVR or the nDVR is associated with the user. In some embodiments, the user may be alerted as to which of the desired properties the stored updated version has (and/or their classification/ranking, if applicable). The user may be alerted via, for example, the graphical user interface of the set top box or IP set top box. Although Fig. 2 shows particular steps for a process of automatically updating stored content, other examples of the process may add, omit, replace, repeat, and/or modify one or more steps.

[0023] Referring to FIG. 3, a flowchart is shown of another example process of updating stored content, which may be performed, for example, by OTT server(s) 110. At 302, an updated version of content that is stored on one or more OTT server(s) and that was viewed or downloaded by a user is monitored. In other words, monitoring is performed to check for the availability of one or more updated versions of the above content. [0024] Monitoring may be performed automatically without user action or intervention, and/or may be performed in response to user action or request. In some embodiments, there may be historical data regarding user’s desired properties for updated versions of content, such as updated versions of content that was previously viewed or downloaded by the user. Examples of desired properties for updated versions of content are described above. In some embodiments, the desired properties may be classified or ranked by relevance. In some embodiments, monitoring may be performed automatically when the content that was viewed or downloaded does not include one or more (or most or all) of the user’s desired properties based on the historical data.

[0025] At 304, an updated version of the stored content is detected. The detection may be for any updated version of the stored content and may be performed in any suitable ways. For example, in some embodiments, the number of packet identifiers in the content are identified. Detecting an updated version of content includes detecting a version that includes more packet identifiers than the content that was previously viewed or downloaded by the user from the OTT server. Additionally, in some embodiments, detecting an updated version includes determining components of program map table(s) and/or other intrinsic transport stream parameter(s) of the content that was previously viewed or downloaded by the user from the OTT server and identifying one or more updated versions that includes more components in its program map table(s) and/or other transport stream(s) as compared to the program map table(s) and/or other transport stream(s) of the content that was previously viewed or downloaded by the user from the OTT server. In some embodiments, any suitable combination of the above methods may be used for detecting.

[0026] In some embodiments, the detection may be only for updated versions of the stored content that includes one or more desired properties or some or all of the desired properties. In those embodiments, method 300 may include determining whether or not an updated version has any, some, or all of the desired properties. In other words, the detection step may be limited to detecting updated versions that include one or more desired properties, some, or most of the desired properties, or all of the desired properties. When the desired properties are classified or ranked, the detection may, in some embodiments, be limited to one or more, most, or all of the critical or important desired properties. The desired properties may be from user input for those particular updated versions. Alternatively, or additionally, the desired properties may be from historical user data, such as historical user data from updated versions of content that was previously viewed or downloaded by the user from the OTT server.

[0027] At 306, the user is alerted of the updated version on the OTT server. In some embodiments, the user may be alerted as to which of the desired properties (and /or their classification or ranking, if applicable) the stored updated version has. The user may be alerted via, for example, a graphical user interface of the user device.

[0028] Method 300 may, in some embodiments, include, at 308, receiving input from a user regarding which of the content, which was previously viewed or downloaded by the user from the OTT server, should be monitored for an updated version. In some embodiments, the user input may include one or more desired properties for the updated version of the content, such as the desired properties previously described. Additionally, the user may classify or rank one or more of those desired properties. The user may, for example, be prompted and/or provided with a graphical user interface (GUI) of the user device to select which of the content should be monitored for an updated version, select the desired propert(ies) of the updated version(s), and/or classify or rank the selected desired propert(ies). Although Fig. 3 shows particular steps for a process of updating stored content, other examples of the process may add, omit, replace, repeat, and/or modify one or more steps.

[0029] Referring to FIG. 4, a hardware configuration 400 operable to facilitate automatically updating stored content is shown. The hardware configuration may be configured to implement or execute one or more of the processes performed by any of the various components, engines, modules, and devices described in the present disclosure, including network digital video recorder 116, local digital video recorders 126, 128, and/or content monitoring components 113 and/or 117.
