Currently, television sets, set-top box video systems, cable television systems, satellite broadcasting systems, and other conventional video systems display the last channel watched when the systems are powered up. In many cases, viewers do not necessarily want to watch the last channel viewed. Conventional video systems also provide on-screen programming guides that list programming content available on various channels at various times. However, such on-screen programming guides are typically displayed as a grid of alphanumeric programming information that viewers must read and interpret. Further, such programming guides do not provide a useful and configurable level of personalization specific to a particular viewer. Though some conventional systems provide interactive program suggestion and systems for acquiring program selection history information, such as U.S. Pat. No. 6,425,128, conventional systems do not provide a personalized video program listing in the manner described and claimed herein.
Thus, a system and method for personalized video program listing and targeted content advertising is needed.
In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration, specific embodiments in which the disclosed subject matter can be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the disclosed subject matter.
As described further below, according to various example embodiments of the disclosed subject matter described herein, there is provided a system and method for personalized video program listing and targeted content advertising. The system includes a personalized video program listing generator operable to produce a personalized video program listing. Various embodiments are described below in connection with the figures provided herein.
Various embodiments disclosed herein describe a system and a method to personalize the initial programming content displayed to a viewer on initial activation of a video system at a particular time/day. In particular, 1) the channels that the viewer/subscriber is most likely to watch at that time are presented on the television (TV) screen and/or, 2) the programs most relevant to the subscriber's particular interest are presented on the TV screen in a convenient viewing format. Various embodiments disclosed herein also provide an effective advertising platform based on learned subscriber behavior to capitalize on the fast-growing broadcast and internet advertising markets.
Various embodiments disclosed herein significantly increase the probability that when a subscriber turns on the TV, the subscriber's favorite show is displayed on TV without the subscriber having to resort to channel surfing or viewing a program guide. When a TV is turned on, conventional systems provide a subscriber with the last-viewed channel regardless of when the channel was watched. In contrast, various embodiments disclosed herein provide the subscriber with a personalized list of preferred distributed programming content (e.g. a rank-ordered list of channels), which could be arranged and displayed as a tiled arrangement of thumbnail views of programming content from the subscriber-specific set of channels, which the subscriber is most likely to prefer watching at the time TV viewing is initiated. The display of images related to preferred distributed programming content is beneficial for the viewer/subscriber; because the viewer/subscriber can immediately begin viewing preferred channels without having to read a programming guide. This creates a better user/viewer experience.
One factor in various embodiments described herein is that likely subscriber viewing preferences are related to the time/day the viewing is initiated. For example, a subscriber might have watched “Daily Show with Jon Stewart” on Comedy Central at 11 pm the previous night. When the subscriber turns on the TV on the following evening at 8 pm, the probability is low that the subscriber would like to watch Comedy Central (or the same channel) at that time. The probability is very small because the subscriber's chosen program on the previous evening, “Daily Show with Jon Stewart”, is not going to be aired until 11 pm on the following evening. Thus, a subscriber's viewing preferences likely vary depending on the time/day the viewing in initiated.
In a manner described in more detail below, various embodiments disclosed herein display a set of the most likely preferred program channel content, as preferred by a particular subscriber at a particular time/day. These most likely preferred channels, denoted Top X channels, (e.g., X=1, 2, 4, etc, channels) represent the video content the particular subscriber is most likely to prefer at the particular time/day based on subscriber-specific information collected automatically by the system. Various embodiments collect subscriber-specific information including a channel/content viewing history for a particular subscriber. Various embodiments can also obtain automatically generated or explicitly entered subscriber profile information, such as demographic information, geographical information, and the like, which is associated with a specific subscriber. In one embodiment, this subscriber-specific information is collected periodically in real time, e.g., on a 30-minute interval. Based on this subscriber-specific information, various embodiments deduce the Top X channels that the subscriber is most interested in at each time interval based on the subscriber's viewing history and other subscriber viewing profile information. Then, various embodiments display the Top X channels on a TV screen as a rank-ordered list of channels, which could be arranged and displayed as a tiled arrangement of thumbnail views of programming content from the subscriber-specific Top X set of channels. In one embodiment, the tiled arrangement of thumbnail views of programming content can be displayed as different picture-in-picture (PIP) streams, which are laid out as 1×2, 2×2, or m×n in general, “mosaic” pieces. The mosaic screen can be automatically updated based on the subscriber's interest and depending on the time/day when the TV activated. In one embodiment, the most relevant (e.g. most likely subscriber preferred) channel is laid out first and highlighted on the TV screen. Additionally, such mosaic screens on a particular TV screen can be presented based on the identity of a logged-in subscriber. Thus, the capture of subscriber-specific information as described above can be based on the identity of a logged in subscriber. In this manner, various embodiments can present a Top X set of likely preferred content in a mosaic presentation on a TV screen for a specific logged-in subscriber. A different logged-in subscriber might therefore see a different Top X set of likely preferred content in a mosaic presentation on the same TV screen. Various embodiments therefore provide a highly personalized set of preferred content viewing options.
Various embodiments disclosed herein can substantially increase subscriber satisfaction and differentiate video distribution and programming services competing with cable, satellite, or IPTV services by significantly increasing the probability that when a subscriber turns on the TV, the subscriber's favorite show(s) is automatically displayed on the TV without the subscriber having to resort to channel surfing or program guide manipulation.
Additionally, various embodiments disclosed herein provide an effective advertising platform to capitalize on the fast-growing broadcast and internet advertising markets to generate a new revenue stream. In a manner described in more detail below, various embodiments can use the subscriber-specific information captured as described above to generate a set of targeted advertisements particularly suited to a particular subscriber based on the subscriber-specific information. The targeted advertising can be displayed as part of the mosaic presentation as described above. As such, on initial activation of a TV set, the subscriber is presented with a mosaic presentation showing the subscriber the Top X set of likely preferred content and a set of targeted advertisements specifically suited to the particular subscriber. Further, the mosaic presentation can include video-on-demand (VoD) channels, pay-per-view channels, or special programming likely to be of interest to a particular subscriber based on the subscriber-specific information. The subscriber-targeted advertisements would typically be sponsored ads provided by a merchant or advertiser. The merchant or advertiser sponsors bid for the placement of their advertising content in the mosaic presentation on the TV set. In most cases, the higher the bid, the higher the rank in the mosaic presentation and the better positioned the ad will be in the mosaic presentation. The merchant or advertiser sponsors or the video content providers/distributors can be charged fees and/or a commission for each visit a subscriber makes to a merchant location as a result of the targeted advertising.

In one example embodiment of the IPTV video delivery system, the SHO 210 distributes content to one or more VHOs 220, which may be spread across a wide geographic territory, such as an entire country. The SHO 210 may, for example, be in a central location for acquisition and aggregation of national-level broadcast TV (or linear) programming. A redundant SHO 210 may be provided for backup in case of failure. The SHO 210 may also provide the central point of on-demand content acquisition and insertion into the IPTV network. Linear programming may be received at the SHO 210 via satellite and processed for delivery to the VHO 220. On demand content may be received from various sources and processed/encoded to codec and bit-rate requirements for the communication network for transmission to the VHO 220 over the high speed communication links. The VHOs 220 are the video distribution points within each demographic market area (DMA) or geographic region.

Also provided in the VHO 220, or alternatively at another distribution point in the IPTV network such as the SHO 210, IO 230, or CO 240, is an additional digital video recorder (DVR) server 425 that acquires live television programming, records the programming/channels in digital form, and distributes the recorded content to subscribers 250 using a unicast data stream in the same manner as server 430. DVR server 425 may be connected to, in one example embodiment, one or more mass storage devices or systems 427, such as magnetic disk drives or optical recording systems. In addition, DVR server 425 includes software 426 to support interaction with subscribers 250 through STB 340. For example, subscribers 250 can, interact with the DVR server 425 using a remote control 350 and an STB 340 to request programming be saved, view saved programming on their own list of saved content, and request delivery of the saved content to them from DVR server 425. Alternatively, in another embodiment, the functions described for DVR server 425 may be performed by a single acquisition server such as server 420 or VOD server 460, and DVR server 425 can be eliminated in whole or in part. The subscribers 250 may request content recorded on DVR server 425, which is delivered, in one example embodiment, with unicast data streams 490A, 490B, or 490C.
According to one embodiment, access to regularly scheduled programming on the television channels, or alternatively access to programming recorded under the control of DVR server 425, may be controlled by an STB 340 in the subscriber 250's premises. Thus, in one example embodiment, each subscriber 250 receives live television programs from the video acquisition server 420 based on IP-based multicasting services, while the video distribution servers 430 are used to provide subscribers 250 “instant” channel change and recover video packet losses to maintain acceptable quality of service. Further, the DVR server 425 provides recorded television programming upon demand by subscribers 250 as more fully described herein.
According to one example embodiment, TV shows may be monitored on the subscriber 250 side, for example in the STB 340. On the subscriber 250 side, the STB 340 receives subscriber 250-initiated control commands from, for example the RC 350, such as channel changes, video-on-demand program ordering, and other control information. This information can be used to collect accurate subscriber-specific information representing the viewing history for a particular subscriber 250 based on TV viewing information accessible in each individual subscriber's 250 STB 340. Alternatively, if such subscriber-specific information is not available from the STB 340, subscriber 250 viewing information can be obtained from the RG 330 based on IP multicast information obtained from the RG 330. In another embodiment, the subscriber 250 viewing information may be obtained from the VHO 220 based on, for example, channel-change requests sent from the STB 340 to the video distribution server 430 in VHO 220. In another embodiment, the subscriber 250 viewing information may be obtained from a subscriber profile maintained as part of the subscriber's account with the video distribution or programming service. Further, a subscriber viewing profile can be explicitly provided or updated by the subscriber via a TV menu interaction or a web-based user interface. A subscriber viewing profile can also be automatically provided or updated based on a subscriber's viewing history and behavior, demographic information, geographic information, transaction history, and the like. As a result, subscriber 250 channel-change and profile information can be collected from the STB 340, the video distribution server 430, and/or other sources and stored in an accessible location for the generation of a personalized list of preferred video content. Collection of subscriber 250 program viewing and profile information may be orchestrated by software in STB 240, software in a separate personalized video program list generator 130 (shown in
Although the system and method as described above is shown in an example form implemented in an IPTV distribution system, the disclosed system and method may, in another example embodiment, may be implemented in a cable television system, in a broadcast television system, in a satellite distribution system, in a wireless distribution system, or in other distribution systems.

The software 924 may further be transmitted or received over a network 926 via the network interface device 920 utilizing any one of a number of well-known transfer protocols, for example, the hyper text transfer protocol (HTTP). While the machine-readable medium 922 is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the disclosed subject matter, or that is capable of storing, encoding, or carrying data structures utilized by or associated with such a set of instructions. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals.
Although the present specification describes components and functions implemented in the embodiments with reference to particular standards and protocols, the disclosed subject matter may be not limited to such standards and protocols. Each of the standards for Internet and other packet switched network transmission (e.g., TCP/IP, UDP/IP, HTML, and HTTP) represent examples of the state of the art. Such standards are periodically superseded by faster or more efficient equivalents having essentially the same functions. Accordingly, replacement standards and protocols having the same functions are considered equivalents.
Thus, system and method for personalized video program listing and targeted content advertising is disclosed. While the example embodiments herein are generally illustrated in the environment of an IPTV system, in an alternative embodiment a cable distribution system or satellite distribution system may be used instead. Such a system may or may not use IPTV methodologies. Other available distribution techniques may be used instead, such as frequency modulation or each channel in a television frequency band, or time division or orthogonal frequency division multiplexing, for example only and not by way of limitation. Further, the IPTV may be delivered over-the-air using, for example, broadband wireless telecommunications techniques.
