Patent Application
20090265742
The present invention relates generally to online viewing of digital content, and, more specifically, to a system and method for providing a user with a user-specific list of program choices based on user profile information stored on the user's digital video recording device (DVR).
A digital video recorder (DVR) or personal video recorder (PVR) is a device that records video in a digital format to a disk drive or other medium. The term includes stand-alone set-top boxes and software for personal computers which enables video capture and playback to and from disk. The term also includes televisions with DVR hardware and software built into the television itself.
DVRs have become very popular. One obvious reason for their popularity is the convenience they offer users in “time shifting” programs. Specifically, DVRs allow users to schedule recordings of broadcast programs, which then can be viewed later, at a convenient time for the user.
Another perhaps less obvious reason for the popularity of DVRs is their ability to organize programming choices. Specifically, DVRs use the metadata provided in programs recorded or scheduled for recording to provide informative lists of programs available for viewing. Because the user must select the programs to be recorded, only programs of interest to the user are listed. Furthermore, more advanced DVRs allow the list to be customized according to a user's needs. For example, it may prioritize programs on the list according to those that remain unwatched, and, likewise, deemphasize or even delete those that have already been watched or make suggestions of related shows. Essentially, the DVR functions to list programs of particular interest to a user in a meaningful and helpful way.
More frequently, users are viewing programs online (i.e., over a wide area network such as the Internet). For example, when traveling or in a location where access to cable or satellite television is limited, a user may be forced or prefer to watch programs online using a remote device. As used herein, a “remote device” is any device capable of playing digital content transmitted over a wide area network such as the Internet. Typical remote devices include, for example, personal computers, cell phones, smart phones, PDAs, and TVs interfaced with a set top box suitable for connection to the Internet.
Recently, devices have been developed to transmit the programming from a user's DVR over the Internet to a remote device. One popular device for transmitting DVR content over the Internet is sold by Sling Media of San Mateo, California under the name “SlingBox”. This device connects a TV source to an existing Internet connection. Software on a user's computer or remote device connects to the SlingBox and provides the user interface for viewing the video stream and changing channels. The SlingBox uploads the digital content from the DVR to a server, which then transmits the content to the remote device over the Internet.
Although this approach exploits the benefits of the DVR with respect to both time shifting and organization, the quality of these transmissions is significantly diminished. Specifically, the upstream bandwidth of a user's Internet connection is dependent on many factors, including the type of connection (e.g., cable, DSL, wireless), the Internet service providers specific configuration of the network, and network traffic at any particular time. If sufficient bandwidth is not available, which is often the case, the digital content must be truncated, thus diminishing its quality.
In addition to reduced quality, transmitting programs over the Internet from DVRs raises legal issues. Specifically, although time shifting is regarded as legally acceptable, the legality of transmitting prerecorded programs over the Internet to remote devices remains unresolved. Such online transmissions may be regarded as copyright infringement unless proper rights have been secured.
Therefore, a need exists for users to enjoy online programming while exploiting the organizational advantages of their DVRs without compromising on the quality or legality of the programs being transmitted.
The present invention provides a system and process for online viewing of a user-specific list of programs based on a profile of the user stored in the user's DVR. Specifically, applicants recognize that DVRs are popular not only because of their time shifting capabilities, but also because of their organization features. These organization features distinguish DVR time shifting from other types of time shifting such as video on demand (VOD) and online streaming. There are circumstances, however, in which DVR use is limited and online viewing is preferred. In such circumstances, the system of the present invention communicates with the user's DVR to obtain the user's profile, which contains viewing preferences organized in a meaningful way, and then provides this information in a User's Menu on a user's remote device via the Internet. In this way, the user has his DVR user profile and related information—such as preferences, stored programs, and entitlement (rights) to view specific content—available to make online viewing choices.
The system and method of the present invention offer significant benefits over the prior art. For example, only programs of interest to the user are displayed on the User Menu, thus simplifying the user's choices from a sea of online viewing possibilities. In addition to listing only those programs of interest to the user, the user-specific User Menu may impart the organizational features of the DVR. These organizational features may include, for example, prioritizing unwatched programs, listing the programs of a series sequentially, listing programs based on recording date, showing other programs in that series, etc. Furthermore, optionally the system can interact with an online content server to list only those programs from the user profile that are available for online viewing. Thus, the user does not waste time selecting programs for online viewing which are not available. Aside from providing the user-specific User Menu, the system of the present invention may also interface the user with a content server for downloading or streaming a selected program from the list to the remote device for viewing. Additionally, the system may be used to update the user profile in the user's DVR after a program has been watched online. Still other features and benefits of the present invention will be clear to one of skill in the art in light of this disclosure.
Accordingly, one aspect of the invention is a system for providing a user-specific list of programs for online viewing based on a user profile stored in a DVR of a user. In one embodiment, the system comprises; (a) a preference server linked to a wide area network and in communication with the DVR and at least one content server having a library of programs available for online delivery to a remote device; and (b) the User Menu being a web site hosted by the preference server and particular to the user, providing the user-specific list of programs based on the user profile stored in the DVR. Preferably the web site is interactive to allow the user to select a desired program from the user-specific list to watch online, and then to instruct the content server to provide the program online to the user. Other embodiments could include the User Menu being customized for display on different types of remote devices possessed by the user such as mobile phones, or PDAs, according to the unique characteristics and display requirements for the device.
Another aspect of the invention is a process for providing a user-specific list of programs based on a user profile stored in a DVR of a user. In one embodiment, the process comprises: (a) hosting a User Menu particular to the user, the User Menu containing a user-specific list of programs based on the user profile; (b) communicating with the DVR periodically to obtain changes to the user profile; and (c) updating the user-specific list with changes to the user profile.
Referring to
The DVR may be one or more devices that can record digital content. Although the digital content is typically audio-visual, it should be understood that the present invention is not limited to audio-visual content, and may include just audio content. Furthermore, the DVR may be a virtual DVR, meaning that a physical DVR does not exist, but rather one is maintained on the internet (or network belonging to the user's cable television, or other television/audio service provider) as if it did exist. For example, even if user does not have a DVR, he may configure his virtual DVR to indicate the programs he is interested in recording. In other words, the present invention requires a user profile of programming preferences on which to base the user-specific list. This user profile may be stored in an actual DVR or it may be created in a virtual DVR. It makes no difference to the system of the present invention.
DVRs are well known and, as mentioned above, function both to time shift and to organize digital content. With respect to organizing digital content, DVRs establish a “user profile” in the form of the metadata corresponding to the recorded programs or the programs scheduled for recording. Metadata may include the name of the program, sequence number, time recorded, network, etc. Preferably, DVRs can be programmed to record particular programs automatically, for example, record each of a series of programs (e.g., Sopranos), certain types of programs (e.g., Westerns), or discrete, one-off, programs.
In addition to these recording preferences, DVRs may also organize the digital content based on several and alternative criteria as mentioned above. For example, a DVR may list preferentially those shows not yet watched. For example, if a certain series of programs has been recorded, it may list them sequentially in the proper order to be viewed. The DVR may also list programs based on their recording date. For example, the oldest recorded shows may be listed first to prompt the user to view these programs so they can be deleted to make room for other recordings. The DVR may also function to eliminate shows that have already been watched to free up space for new programs to be recorded. Thus, the DVR provides a user profile of only those programs of interest to the user, organized in a meaningful way.
The User Menu 105 is particular to the user, meaning that, in one embodiment, every user has his own Internet site containing his own user-specific list of programs for online viewing. The user's User Menu is accessible online using the remote device(s). The User menu may be in the form of a web page, downloadable client, or some format customized for a particular device, as long as it is delivered over the Internet.
The content server 102 functions to provide digital content online to a remote device as defined above. The content server 102 may be one of a plurality of content servers monitored by the preference server 103 for providing on-line digital content as described below. Such content servers are well known and are becoming more popular. The content server contains a library 109 of available online programs. Preferably, the appropriate rights to download, stream or otherwise transmit online is secured for each of the programs in the library by the owner of the content server. Importantly, in one embodiment, the content server(s) need not be controlled by the same party providing the User Menu, but rather by one or more third parties.
Different users may possess different “entitlements” or rights to view particular content provided on particular content servers. Optionally, the preference server can interface with content server(s) to determine the content available to a specific user by different entitlement criteria which may be specific to that user. For example, if content on a particular content server is available on a subscription basis, the preference server is able to know if a user possesses the required subscription as part of the user's profile, and can provide the availability of that content on the User Menu to that user only.
By using a content server to download the digital content, higher quality streaming is available. The content server may stream the video directly to a remote device or, alternatively, it may transmit the digital content to the preference server, which, in turn, may download the content to the remote device. Either way, since the digital content is being downloaded from a server to a remote device, it has the advantage of a broad downstream link. That is, downstream links generally have higher bandwidth than upstream links. Consequently, digital content can be streamed with higher resolution than possible with SlingBox-like devices, which as mentioned above can be limited by the upstream link from the SlingBox to the Internet server. For example, a content server can currently download streaming video at a bandwidth rate that is a multifold increase over typical SlingBox transmission rates.
The preference server functions to pull together information from at least one user DVR and at least one content server, and to display a user-specific list of programs based on this information on a User Menu that it hosts.
The preference server interacts with at least one user DVR to obtain the user profile and to update the user-specific list of programs. This update may be performed every time the user goes to the User Menu or automatically by the preference server at predetermined intervals. To this end, it may communicate with the user's DVR(s) over the Internet, or through a point-to-point connection. Preferably, the preference server communicates with the DVR(s) over the Internet. Furthermore, if the user has more than one DVR, the preference server would communicate with each one to form a comprehensive user profile. Likewise, the preference server may form unique profiles for multiple users within a single home (i.e., common DVR). For example, when one user views an initial User Menu based on the common DVR, he can select/deselect programs particular to his preferences, and the preference server will build a sub-profile for this user for future use, but other users sharing the common DVR will not have their User Menu affected by his preferences.
The preference server also functions to interface with one or more content servers. This interface may be via the Internet or a point-to-point connection. Preferably, the interface is over the Internet. This allows the preference server to monitor different content servers and keep track of what programs are available for download from which content servers. To this end, the preference server periodically combs the Internet for content servers and updates a content server database 110 containing locations for downloading particular programs. Alternatively, the preference server and content server can be integrated in a common computer or server.
In one embodiment, the preference server compares the user profile from one or more DVRs to the available programs in the content server database 110. The user profile then is modified such that the user-specific list of programs contains only those programs available for online viewing. Alternatively, rather than conforming the user profile of the DVR to the available programming on a content server, the preference server may instead provide the user's profile on the User Menu, but wait to determine downloading availability until after the user selects a program from the user-specific list as described below.
Preferably, the User Menu is interactive meaning that it is responsive to a user's input. For example, in a preferred embodiment, the User Menu provides the user-specific list of programs based on the user profile and allows the user to select which of those programs it would like to watch online. Once the program is selected, the preference server facilitates the download of the desired program. To this end, the preference server may instruct a particular content server having the desired digital content to download it directly to the remote device, or, alternatively to transmit the program to the preference server which then downloads it to the remote device. Alternatively, rather than the preference server managing the download of the desired program, the preference server may simply launch the user to the content server web page having the desired program so the user can manage the download of the program from that site.
The preference server may also function to update the DVR. Specifically, in addition to receiving the user profile from the user's DVR, the preference server may also function to update the user profile to reflect programs watched online. For example, the user may be given an option after watching a program online to update its user profile to reflect this. If the user chooses the option, the preference server would then communicate with the DVR and update it accordingly.
In operation, the system of the present invention provides a user-specific list of programs based on a user profile stored in a DVR of a user. Referring to
In step 202, the user profile from the user's DVR is uploaded. As mentioned above, this user profile contains a list of the recorded programs and the programs to be recorded. It may also contain information regarding the organization of the programs including particular sequences and indications of whether the programs have already been watched.
Step 203 is optional and involves the preference server communicating with one or more content servers to determine which of the programs in the user profile are available for online viewing, and then revising the profile accordingly so that a user-specific list of programs based on the user profile only contains programs which are available online.
In step 204, this user-specific list is displayed on the User Menu hosted by the preference server. Optionally, in addition to the user-specific list being based on the user profile in the DVR, it may include information gathered by the preference server based on the user profile. Specifically, the preference server may be configured to search the Internet and other data sources to deduce or infer programs of interest to the user based on the user's profile. The programming and processes allowing the preference server to be configured to perform this function have improved significantly in recent years.
As mentioned above, the User Menu is preferably interactive to allow the user to select programs to watch online from the user-specific list provided. Accordingly, in step 205, the user selects a program to watch online. At this point, the preference server may direct the content server to download the program directly to the user's remote device, or the preference server may receive the program from the content server and then download it to the user's remote device. Alternatively, the preference server may launch the user to a content server web site where the desired program is available for download. Still other download scenarios are possible. For example, the content server may transmit the program to a third party download server, specifically configured for downloading programs.
In step 206, the preference server updates the User Menu. This may involve simply contacting the DVR periodically to determine changes to the user profile. Alternatively, this step may be performed each time the user logs on to the User Menu. In yet another embodiment, this is done after the user affirmatively requests an update. Still other updating scenarios are possible.
Optionally, the system not only updates the User Menu, but also updates the user profile on the DVR. Accordingly, in step 207, the system communicates with the DVR to update the user profile to reflect any shows that may have been watched online. In this respect, the system may ask the user if the DVR should be updated or automatically update it after a selection is made from the user-specific list of programs on the User Menu.
Using the system and method of the present invention as described above offers significant benefits over the prior art. For example, only programs of interest to the user are displayed on the User Menu, thus simplifying the user's choices from a sea of online viewing possibilities. In addition to listing only those programs of interest to the user, the user-specific list may impart the organizational features of the DVR. These organizational features may include, for example, prioritizing unwatched programs, listing the programs of a series sequentially, listing programs based on recording date, etc. Furthermore, optionally the system can interact with an online content server to list only those programs from the user profile that are available for online viewing. Thus, the user does not waste time selecting programs for online viewing which are not available. Aside from providing the user-specific list, the system of the present invention may also interface the user with a content server for downloading a selected program from the list to the remote device. Additionally, the system may be used to update the user profile in the user's DVR after a program has been watched online. Still other features and benefits of the present invention will be clear to one of skill in the art in light of this disclosure.
It should be understood that the description above provides illustrative embodiments of the present invention and other embodiments exist.
