Abstract

Television programs are represented by program interface objects (PIOs) within an interactive television system. The PIOs provide at least one visual indicator for quick identification of the represented television program, attributes providing information concerning the represented television program, and actions that may be performed on or in connection with the represented television program. The PIOs may be sorted, filtered, and/or managed based on user-provided criteria. The PIOs may be transmitted between a variety of electronic devices and software applications.

    RELATED APPLICATIONS
  • [0001]
    This application is a continuation-in-part of U.S. patent application Ser. No. 09/909,468, filed Jul. 19, 2001, for “Object Representation of Television Programs within an Interactive Television System,” with inventor Thomas P. McKenna, Jr., which is hereby incorporated by reference.
  • BACKGROUND
  • [0002]
    1. Field of the Invention
  • [0003]
    The present invention relates generally to the field of interactive television systems. More specifically, the present invention relates to a system and method for sharing television program information between entertainment devices.
  • [0004]
    2. Description of Related Background Art
  • [0005]
    Due to the ever-increasing number of channels offered by cable television and satellite networks, an electronic program guide (EPG) has become a common feature of many set top boxes (STBs). Conventional EPGs display schedule information for television programs in a grid-based format. One axis of the EPG typically corresponds to channels or stations, while the other axis corresponds to time slots. Rectangular elements formed within the grid represent specific television programs.
  • [0006]
    While EPGs have numerous advantages over conventional printed guides (such as TV Guide®), EPGs are still based on the channel/time slot model, which is of diminishing importance today. For example, where a viewer has access to over 500 channels, he or she is not interested in the fact that the latest episode of Friends® is being shown on Channel 498. Rather, the viewer would simply like to know when the program is being broadcast and allow the entertainment system to automatically switch to the appropriate channel.
  • [0007]
    With the advent of digital video recorders (DVRs), even the concept of broadcast time is becoming irrelevant. Ideally, a viewer would simply like to instruct the entertainment system to record the next episode of Friends®, which the viewer can then watch at a convenient time.
  • [0008]
    Forcing a viewer to search through a grid consisting, for example, of over 500 rows (corresponding to channels) and possibly thousands of columns (corresponding to time slots) is no longer acceptable. Given the wide variety of entertainment options and the limited amount of time available to individuals for entertainment, any advancement increasing the convenience of an entertainment system would be highly advantageous.
  • [0009]
    Accordingly, what is needed is a system and method that overcomes the problems and disadvantages of the prior art. In particular, the system and method should provide convenient access to available programming within an entertainment system without requiring the use of a conventional, grid-based EPG.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0034]
    The present invention solves the foregoing problems and disadvantages by using program interface objects (PIOs) to represent television programs within an entertainment system, such as interactive television system.
  • [0035]
    In one embodiment, each PIO includes a plurality of actions and attributes. Actions correspond to various operations that may be performed on or in connection with the television program represented by the PIO. For example, one action may schedule the recording of the represented television program, while another action may play back the represented television program if it was previously recorded. Actions may be embodied as program code, in a machine-independent format, such as Java or Javascript, that may be executed, for example, by an STB for an interactive television system.
  • [0036]
    Attributes contain information about the television program represented by the PIO. For example, one attribute of a television program may correspond to the program's name, while another attribute may correspond to the program's broadcast time.
  • [0037]
    Certain attributes may contain meta-data relating to the PIO, the television program, or both. For example, one attribute may indicate the size of the corresponding PIO. Another attribute may indicate the encoding format of the television program.
  • [0038]
    Attributes may be used to sort, filter, prioritize, or otherwise organize a set of PIOs. Moreover, certain attributes may be used in the context of certain actions. For example, an action for recording a television program may need to access attributes containing the channel, starting time, and running time of the television program.
  • [0039]
    PIOs may be implemented using various technologies. For instance, a PIO may be implemented as a JavaBean object. Alternatively, a PIO may be embodied as a Distributed Component Object Model (DCOM) object or an eXtensible Markup Language (XML) object. The present invention is not limited to a particular object format.
  • [0040]
    In one implementation, each PIO also includes a visual indicator, such as an icon, which is displayed in a graphical user interface (GUI) to facilitate user interaction with the PIO. The GUI may display a plurality of visual indicators corresponding to a set of PIOs. Using a remote control or other selection mechanism, a user may select a PIO by its corresponding visual indicator. Further, a user may select an action associated with the PIO, which then may be executed by the STB.
  • [0041]
    In one embodiment, an STB or other system may be populated with visual indicators of a set of PIOs selected from a larger set of available PIOs. The set of available PIOs may be filtered based on user-defined filtering criteria. For example, a user may filter the set of available PIOs for ones relating to sporting events.
  • [0042]
    In certain embodiments, PIOs may be transmitted between interactive television systems, personal computers, mobile devices, and the like. For example, a PIO may be attached to an e-mail message and sent via the Internet to another system where it may be used to perform various actions on, or provide information concerning, a represented television program. Alternatively, a PIO may be sent via infrared (IR) or radio frequency (RF) transmission from one portable entertainment device, such as a Personal Digital Assistant (PDA), to another.
  • [0043]
    Thus, PIOs are an alternative mechanism for providing access to available television programming within an interactive television system, without the necessity of a conventional EPG. A user need not be concerned with such details as channel or broadcast time, as was necessary in conventional systems. The user need only select an icon for a PIO and select the desired action.
  • [0044]
    Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment.
  • [0045]
    Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of programming, user selections, network transactions, database queries, database structures, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
  • [0046]
    Referring now to FIG. 1, there is shown a communication system 100. In one implementation, the system 100 relies on a broadband network 101 for communication, such as a cable television network or a direct satellite broadcast (DBS) network, although other networks are possible.
  • [0047]
    The system 100 may include a plurality of set top boxes (STBs) 102 located, for instance, at customer homes or offices. Generally, an STB 102 is a consumer electronics device that serves as a gateway between a customer's television 104 and the network 101. In alternative embodiments, an STB 102 may be embodied more generally as a personal computer (PC), an advanced television 104 with STB functionality, or another type of client terminal.
  • [0048]
    An STB 102 receives encoded television signals and other information from the network 101 and decodes the same for display on the television 104 or other display device, such as a computer monitor. As its name implies, an STB 102 is typically located on top of, or in close proximity to, the television 104.
  • [0049]
    Each STB 102 may be distinguished from other network components by a unique identifier, number, code, or address, examples of which include an Internet Protocol (IP) address (e.g., an IPv6 address), a Media Access Control (MAC) address, or the like. Thus, video signals and other information may be transmitted from the network 101 to a specific STB 102 by specifying the corresponding address, after which the network 101 routes the transmission to its destination using conventional techniques.
  • [0050]
    A remote control 106 is provided, in one configuration, for convenient remote operation of the STB 102 and the television 104. The remote control 106 may use infrared (IR), radio frequency (RF), or other wireless technologies to transmit control signals to the STB 102 and the television 104. Other remote control devices are also contemplated, such as wired or wireless mice (not shown).
  • [0051]
    Additionally, a keyboard 108 (either wireless or wired) is provided, in one embodiment, to allow a user to rapidly enter text information into the STB 102. Such text information may be used for e-mail, instant messaging (e.g. text-based chat), or the like. In various embodiments, the keyboard 108 may use infrared (IR), radio frequency (RF), or other wireless technologies to transmit keystroke data to the STB 102.
  • [0052]
    Each STB 102 may be coupled to the network 101 via a broadcast center 110. In the context of a cable television network, a broadcast center 110 may be embodied as a “head-end”, which is generally a centrally-located facility within a community where television programming is received from a local cable TV satellite downlink or other source and packaged together for transmission to customer homes. In one configuration, a head-end also functions as a Central Office (CO) in the telecommunication industry, routing video signals and other data to and from the various STBs 102 serviced thereby.
  • [0053]
    A broadcast center 110 may also be embodied as a satellite broadcast center within a direct broadcast satellite (DBS) system. A DBS system may utilize a small 18-inch satellite dish, which is an antenna for receiving a satellite broadcast signal. Each STB 102 may be integrated with a digital integrated receiver/decoder (IRD), which separates each channel, and decompresses and translates the digital signal from the satellite dish to be displayed by the television 104.
  • [0054]
    Programming for a DBS system may be distributed, for example, by multiple high-power satellites in geosynchronous orbit, each with multiple transponders. Compression (e.g., MPEG) may be used to increase the amount of programming that can be transmitted in the available bandwidth.
  • [0055]
    The broadcast centers 110 may be used to gather programming content, ensure its digital quality, and uplink the signal to the satellites. Programming may be received by the broadcast centers 110 from content providers (CNN®, ESPN®, HBO®, TBS®, etc.) via satellite, fiber optic cable and/or special digital tape. Satellite-delivered programming is typically immediately digitized, encrypted and uplinked to the orbiting satellites. The satellites retransmit the signal back down to every earth-station, e.g., every compatible DBS system receiver dish at customers' homes and businesses.
  • [0056]
    Some broadcast programs may be recorded on digital videotape in the broadcast center 110 to be broadcast later. Before any recorded programs are viewed by customers, technicians may use post-production equipment to view and analyze each tape to ensure audio and video quality. Tapes may then be loaded into a robotic tape handling systems, and playback may be triggered by a computerized signal sent from a broadcast automation system. Back-up videotape playback equipment may ensure uninterrupted transmission at all times.
  • [0057]
    Regardless of the nature of the network 101, the broadcast centers 110 may be coupled directly to one another or through the network 101. In alternative embodiments, broadcast centers 110 may be connected via a separate network, one particular example of which is the Internet 112. The Internet 112 is a “network of networks” and is well known to those skilled in the art. Communication over the Internet 112 is accomplished using standard protocols, such as TCP/IP (Transmission Control Protocol/Internet Protocol) and the like.
  • [0058]
    A broadcast center 110 may receive television programming for distribution to the STBs 102 from one or more television programming sources 114 coupled to the network 101. Preferably, television programs are distributed in an encoded format, such as MPEG (Moving Picture Experts Group). Various MPEG standards are known, such as MPEG-2, MPEG-4, MPEG-7, and the like. Thus, the term “MPEG,” as used herein, contemplates all MPEG standards. Moreover, other video encoding/compression standards exist other than MPEG, such as JPEG, JPEG-LS, H.261, and H.263. Accordingly, the invention should not be construed as being limited only to MPEG.
  • [0059]
    Broadcast centers 110 may be used to enable audio and video communications between STBs 102. Transmission between broadcast centers 110 may occur (i) via a direct peer-to-peer connection between broadcast centers 110, (ii) upstream from a first broadcast center 110 to the network 101 and then downstream to a second broadcast center 110, or (iii) via the Internet 112. For instance, a first STB 102 may send a video transmission upstream to a first broadcast center 110, then to a second broadcast center 110, and finally downstream to a second STB 102.
  • [0060]
    Of course, the communication system 100 illustrated in FIG. 1 is merely exemplary, and other types of devices and networks may be used within the scope of the invention.
  • [0061]
    Referring now to FIG. 2, there is shown an interactive television (ITV) system 200 according to an embodiment of the invention. As depicted, the system 200 may include an STB 102, a television 104 (or other display device), a remote control 106, and, in certain configurations, a keyboard 108.
  • [0062]
    The remote control 106 is provided for convenient remote operation of the STB 102 and the television 104. In one configuration, the remote control 106 includes a wireless transmitter 202 for transmitting control signals (and possibly audio/video data) to a wireless receiver 203 within the STB 102 and/or the television 104. In certain embodiments, the remote control 106 includes a wireless receiver 204 for receiving signals from a wireless transmitter 205 within the STB 102. Operational details regarding the wireless transmitters 202, 205 and wireless receivers 203, 204 are generally well known to those of skill in the art.
  • [0063]
    The remote control 106 preferably includes a number of buttons or other similar controls. For instance, the remote control 106 may include a power button 206, an up arrow button 208, a down arrow button 210, a left arrow button 212, a right arrow button 214, a “Select” button 216, an “OK” button 218, channel adjustment buttons 220, volume adjustment buttons 222, alphanumeric buttons 224, a “Help” button 226, and the like.
  • [0064]
    In one embodiment, the remote control 106 includes a microphone 242 for capturing audio signals. The captured audio signals may be transmitted to the STB 102 via the wireless transmitter 202. In addition, the remote control 106 may include a speaker 244 for generating audible output from audio signals received from the STB 102 via the wireless receiver 204. In alternative embodiments, as shown in FIG. 3, the microphone 242 and/or speaker 244 may be integrated with the STB 102.
  • [0065]
    In certain embodiments, the remote control 106 further includes a video camera 246, such as a CCD (charge-coupled device) digital video camera, for capturing video signals. In one implementation, the video camera 246 is in electrical communication with the wireless transmitter 202 for sending the captured video signals to the STB 102. Like the microphone 242 and speaker 244, the video camera 246 may be integrated with the STB 102, or attached to the STB 102, as in the depicted embodiment.
  • [0066]
    The various components of the remote control 106 may be positioned in different locations for functionality and ergonomics. For example, as shown in FIG. 2, the speaker 244 may be positioned near the “top” of the remote control 106 (when viewed from the perspective of FIG. 2) and the microphone 242 may be positioned at the “bottom” of the remote control 106. Thus, in one embodiment, a user may conveniently position the speaker 244 near the user's ear and the microphone 242 near the user's mouth in order to operate the remote control 106 in the manner of a telephone.
  • [0067]
    The optional keyboard 108 facilitates rapid composition of text messages. The keyboard 108 includes a plurality of standard alphanumeric keys 236. In one configuration, the keyboard 108 includes a wireless transmitter (not shown), similar or identical to the wireless transmitter 202 of the remote control 106. The wireless transmitter transmits keystroke data from the keyboard 108 to the STB 102. Additionally, the keyboard 108 may include one or more of the buttons illustrated on the remote control 106.
  • [0068]
    Alternatively, or in addition, a hands-free headset 248 may be coupled to the remote control 106 or the keyboard 108. The headset 248 may be coupled using a standard headset jack 250. The headset 248 may include a microphone 242 and/or speaker 244. Such a headset 248 may be used to reduce audio interference from the television 104 (improving audio quality) and to provide the convenience of hands-free operation.
  • [0069]
    Referring now to FIG. 3, there is shown a block diagram of physical components of an STB 102 according to an embodiment of the invention. As noted above, the STB 102 includes a wireless receiver 203 for receiving control signals sent by the wireless transmitter 202 in the remote control 106 and a wireless transmitter 205 for transmitting signals (such as audio/video signals) to the wireless receiver 204 in the remote control 106.
  • [0070]
    The STB 102 also includes, in one implementation, a network interface 302 for communicating with the network 101 via the broadcast center 110. The interface 302 may include conventional circuitry for receiving, demodulating, and demultiplexing MPEG packets. The interface 302 may also include conventional modem circuitry for sending or receiving data. For example, the interface 302 may conform to the DOCSIS (Data Over Cable Service Interface Specification) or DAVIC (Digital Audio-Visual Council) cable modem standards.
  • [0071]
    In one configuration, one or more frequency bands (for example, from 5 to 30 MHz) may be reserved for upstream transmission. Digital modulation (for example, quadrature amplitude modulation or vestigial sideband modulation) may be used to send digital signals in the upstream transmission. Of course, upstream transmission may be accomplished differently for different networks 101. Alternative ways to accomplish upstream transmission include using a back channel transmission, which is typically sent via an analog telephone line, ISDN, DSL, or other techniques.
  • [0072]
    The STB 102 also preferably includes a codec (encoder/decoder) 304, which serves to encode audio/video signals into a network-compatible data stream for transmission over the network 101. The codec 304 also serves to decode a network-compatible data stream received from the network 101. The codec 304 may be implemented in hardware and/or software. Moreover, the codec 304 may use various algorithms, such as MPEG or Voice over IP (VoIP), for encoding and decoding.
  • [0073]
    The STB 102 further includes a memory device 306, such as a random access memory (RAM), for storing temporary data. Similarly, a read-only memory (ROM) may be provided for storing more permanent data, such as fixed code and configuration information.
  • [0074]
    In one embodiment, an audio/video (A/V) controller 308 is provided for converting digital audio/video signals into analog signals for playback/display on the television 104. The A/V controller 308 may be implemented using one or more physical devices, such as separate graphics and sound controllers. The AN controller 308 may include graphics hardware for performing bit-block transfers (bit-blits) and other graphical operations for displaying a graphical user interface (GUI) on the television 104.
  • [0075]
    In some implementations, the STB 102 may include a storage device 310, such as a hard disk drive, optical storage device, RAM, compact flash card, etc. The storage device 310 may be configured to store encoded incoming and outgoing video signals as well as television broadcasts and retrieve the same at a later time for display. The storage device 310 may be configured, in one embodiment, as a digital video recorder (DVR), enabling scheduled recording of television programs, pausing (buffering) live video, etc. The storage device 310 may also be used in various embodiments to store viewer preferences, parental lock settings, electronic program guide (EPG) data, passwords, e-mail messages, video messages, video greetings, and the like. In one implementation, the storage device 310 also stores an operating system (OS) for the STB 102, such as Windows CE® or Linux®.
  • [0076]
    As noted above, the STB 102 may include, in certain embodiments, a microphone 242 and a speaker 244 for capturing and reproducing audio signals, respectively. The STB 102 may also include or be coupled to a video camera 246 for capturing video signals. These components may be included in lieu of or in addition to similar components in the remote control 106, keyboard 108, and/or television 104.
  • [0077]
    A CPU 312 controls the operation of the STB 102, including the other components thereof, which are coupled to the CPU 312 in one embodiment via a bus 314. The CPU 312 may be embodied as a microprocessor, a microcontroller, a digital signal processor (DSP) or other device known in the art. For instance, the CPU 312 may be embodied as an Intel® x86 processor. As noted above, the CPU 312 may perform logical and arithmetic operations based on program code stored within the memory 306 or the storage device 310.
  • [0078]
    Of course, FIG. 3 illustrates only one possible configuration of an STB 102. Those skilled in the art will recognize that various other architectures and components may be provided within the scope of the invention. In addition, various standard components are not illustrated in order to avoid obscuring aspects of the invention.
  • [0079]
    [0079]FIG. 4 illustrates one implementation of a conventional Electronic Programming Guide (EPG) 402. As noted above, a typical EPG 402 includes a grid having two axes, one for time slots 404 and the other for channels or stations 406. Rectangular elements 408 formed within the grid correspond to specific television programs.
  • [0080]
    Generally, the navigation interface for a conventional EPG 402 is awkward and ill-suited to entertainment systems having more than a few channels. For example, a satellite STB may receive more than 500 channels, requiring the user to scroll through many pages of information to locate a desired program. Clearly, a conventional EPG 402 is based on the channel/time slot model, which is of diminishing relevance today.
  • [0081]
    For example, where a viewer has access to over 500 channels, he or she is not in interested in the fact that the latest episode of Friends® is being shown on Channel 498. Rather, the viewer would simply like to know when the program is being broadcast and allow the entertainment system to automatically switch to the appropriate channel.
  • [0082]
    With the advent of digital video recorders (DVRs), even the concept of broadcast time is becoming irrelevant. Ideally, a viewer would like instruct the entertainment system to record the next episode of Friends®, which the viewer can then watch at a convenient time.
  • [0083]
    In conventional systems, the EPG 402 may be generated from a text data file 410 or the like containing raw schedule information. For example, each program element 408 in the EPG 402 may correspond to one or more lines in the text data file 410. Unfortunately, storing raw schedule information in this manner severely limits the way in which the information may be used and communicated. For example, each system that receives the text data file 410 must be programmed to parse and display the information in a user-friendly format. The file 410, itself, does not include code or resources for using or displaying the information.
  • [0084]
    [0084]FIG. 5 illustrates an alternative to the conventional EPG 402 in accordance with principles of the present invention. In one embodiment of the invention, program interface objects (PIOs) 502 are used to represent television programs within an entertainment system, such as an interactive television system 200. In the depicted embodiment, a plurality of PIOs 502 are stored within a memory 306 of an STB 102. However, various other systems and devices may be used to store PIOs 502, such as personal digital assistants (PDAs), webpads, personal computers, and the like.
  • [0085]
    As noted above, a PIO 502 may include a plurality of actions 504 and attributes 506. In one embodiment, actions 504 correspond to various operations that may be performed on or in connection with the television program represented by the PIO 502. For example, one action 504 may schedule the recording of the represented television program, while another action may display the represented television program if it was previously recorded or is currently in progress. Of course each PIO 502 may include a different set of actions 504 permitting the PIOs 502 to be sorted and categorized based on the different defined actions 504.
  • [0086]
    Actions 504 may be embodied as program code, in a machine-independent format, that may be executed, for example, by an STB 102 for an interactive television system. Alternatively, actions 504 may include resources that are used by program code within a STB 102 or the like.
  • [0087]
    Attributes 506 contain information about the television program represented by the PIO 502. For example, one attribute 506 may correspond to a television program's name, while another attribute 506 may correspond to the program's broadcast time. Certain attributes 506 may contain meta-data related to the PIO 502, the represented television program, or both. For example, one attribute 506 may indicate the size of the PIO 502. Another attribute 506 may indicate the video encoding format of the represented television program.
  • [0088]
    As described more fully hereafter, attributes 506 may be used to sort, filter, search, prioritize, or otherwise organize a set of PIOs 502. Moreover, certain attributes 506 may be used in the context of certain actions 504. For example, an action 504 for recording a television program may need to access the attributes 506 containing the channel, starting time, and running time of the television program.
  • [0089]
    Each of the attributes 506 in a PIO 502 may include a triplet of information, e.g., the attribute name (Program Title, Program Broadcast Time, Program Broadcast Channel), the attribute's type (searchable text, time, executable code, GIF image, ATVEF triggers and their time mark within the program, MIME, or the like), and the attribute's value. In some cases, attributes 506 may include text in multiple languages to allow the PIO 502 to be used in different countries around the world.
  • [0090]
    PIOs 502 may be implemented using various technologies. For instance, a PIO 502 may be implemented as a JavaBean object. Alternatively, a PIO 502 may be embodied as a Distributed Component Object Model (DCOM) object or an extensible Markup Language (XML) object.
  • [0091]
    In one implementation, each PIO 502 also includes a visual indicator 508, such as an icon, animated image, or video clip, which is displayed in a graphical user interface (GUI) to facilitate user interaction with the PIO 502. As illustrated in subsequent figures, the GUI may display a plurality of visual indicators 508 corresponding to a set of PIOs 502. Using a remote control 106 or other selection mechanism, a user may select a PIO 502 by its corresponding visual indicator 508. Further, a user may select an action associated with the PIO 502 to be executed by the STB 102. In alternative embodiments, a PIO 502 may not include a visual indicator 508, may simply include one more actions 504 and one or more attributes 506.
  • [0092]
    In one embodiment, PIOs 502 include program code in a substantially machine-independent format. For example, JavaBean, DCOM, or XML objects generally do not require proprietary hardware so long as the hardware executes a Java Virtual Machine (JVM), a DCOM server, an XML processor, or the like. The PIOs 502 may be created using a variety of programming languages and protocols, such as Java, C++, Smalltalk, and other programming languages that support object-oriented programming.
  • [0093]
    Machine independence allows the PIOs 502 to be portable. Information and functionality associated with a particular television program are encapsulated within the PIOs 502. PIOs may be transferred between STBs 102 or other devices, such as personal computers and hand-held devices. PIOs 502 may also be stored in computer-readable media, such as CDs, diskettes, memory cards, memory sticks, or the like.
  • [0094]
    Of course, PIOs 502 may be configured in various ways, and may be referred to using different terms, while still being considered within the scope of the invention. For example, “actions” may be termed “methods” or “functions”, and “attributes” may be referred to as “variables”, “state”, or “data”.
  • [0095]
    [0095]FIG. 6 illustrates an expanded view of a PIO 502 including examples of attributes 506, actions 504, and visual indicators 508. For instance, a typical PIO 502 may include such attributes 506 as title 506 a, description 506 b, broadcast channel 506 c, rating 506 d (e.g., TV-G, TV-PG), start time 506 e, end time 506 f, running time 506 g, release year 506 h, classification 506 i (e.g., drama, sit-com, sports), actor(s) 506 j, producer(s) 506 k, related Internet links 506 l, storage location 506 m, country of origin 506 n, language 506 o, etc. Of course, various other attributes 506 may be provided within the scope of the invention.
  • [0096]
    In some cases, attributes 506 may be embodied as references to external data in the form of hyperlinks or the like. For example, where a start time 506 e attribute contains a fixed start time (e.g., 8:00 pm), an STB 102 may not be able to account for scheduling changes by a television source 114. Thus, in certain embodiments, the start time attribute 506 e (and other such attributes 506), may include a link to a server (not shown) that contains the up-to-date start time for the television program. Thus, scheduling changes reflected in the server will be automatically recognized by all corresponding PIOs 502. This is particularly advantageous in the context of a sports game that goes into overtime. For example, the STB 102 can get updates from the broadcaster, allowing the STB 102 to extend the duration of the recording of the program.
  • [0097]
    In other embodiments, one or more attributes 506 of a PIO 502 may be dynamically updated based on (possibly real-time) updates from a broadcaster using a transmission method that can be specified in the PIO 502. The transmission methods can include, for instance, HTTP, FTP, e-mail, or an ATVEF trigger.
  • [0098]
    One particularly advantageous attribute 506 is the is the related Internet links attribute 506 l. The related Internet links attribute 506 l may link a PIO 502 to an associated web site (e.g., a sponsored link), a chat room (e.g., real time chat about the television program being watched), or an e-commerce site.
  • [0099]
    In certain embodiments, one attribute 506 may comprise a link (not shown) to one or more other PIOs 502. This facilitates PIO linking, which is advantageous, for example, in the context of related PIOs 502, e.g., a miniseries.
  • [0100]
    A typical PIO 502 may also include various actions 504, such as an action 504 a for recording the associated television program. As described more fully below, the recording action 504 a may operate in conjunction with the CODEC 304 and storage device 310 of FIG. 3 to digitally record the television program when it is broadcast by a television source 114 or streaming video source 116. In addition, the recording action 504 may access the channel, start time, end time, and/or running time attributes 506 c, 506 e-g in order to facilitate the recording. The instantiation of a PIO 502 as stored in the STB memory 306 may contain additional, or updated data and may not be exactly the same as the originally broadcast PIO 502. The recording action 504 a is an example of this dynamic update of the stored copy of the PIO 502.
  • [0101]
    An action 504 b may also be provided for displaying the represented television program on a television 104. If, for instance, the television program is currently being broadcast, the display action 504 b may be configured to tune the STB 102 to the correct channel. If, however, the television program was previously broadcast and recorded (e.g., by the record action 504 a), the display action 504 b may retrieve and display the stored television program. In one embodiment, the display action 504 accesses the storage location 506 m attribute to locate a stored television program.
  • [0102]
    Various other actions 504 may include an action 504 b for reminding a user that a particular program is scheduled to be broadcast and/or reminding the user that the program has been recorded. Additionally, an action 504 d may be provided for displaying one or more attributes 506 of the PIO 502 on the television 104 or other display device. Moreover, an action 504 e may be included to allow a user to rate and/or comment on the represented television program. An action 504 f may also be provided to send a copy of the PIO 502 to another system or device.
  • [0103]
    In some cases, actions 504 may be propagated between linked PIOs 502. For example, a user may selection the record action 502 a of a PIO 502 corresponding to a program in a mini-series. If the PIOs 502 of the mini-series are linked (e.g., by an appropriate attribute 506 or the like), then the same action 506 a may be executed by the linked PIOs 502 as well.
  • [0104]
    Of course, numerous other attributes 506 and actions 504 may be provided within the scope of the invention. Moreover, the object-oriented nature of a PIO 502 allows for additional actions 504 and attributes 506 to be dynamically added as necessary.
  • [0105]
    The PIO 502 may also include a visual indicator 508, such as a graphical icon, to facilitate interaction with the PIO 502 in the context of a GUI. A visual indicator 508 may alternatively, or in addition, include a textual description of the television program, such as the program's name.
  • [0106]
    A graphical visual indicator 508 is advantageous in that it overcomes language and illiteracy barriers presented by conventional EPGs 402. For example, a child user may be unable to read a text description. However, a Big Bird® icon would be clearly recognizable as representing Sesame Street®.
  • [0107]
    In certain embodiments, a PIO 502 may include an audible indicator 509. The audible indicator 509 may include, for example, a description of the television program associated with the PIO 502 (similar to the description attribute 506 b), an advertisement, user instructions, theme music for the television program or the like. The audible indicator 509 may be embodied as an audio clip or sample, which is played back by the STB 102 when the PIO 502 is selected or when the corresponding visual indicator 506 is displayed. The inclusion of an audible indicator 509 is advantageous for people who are visually disabled or those who have difficulty reading.
  • [0108]
    Referring now to FIG. 7, there is shown a block diagram of logical components of a system 700 that utilizes PIOs 502 to represent television programs. The depicted logical components may be implemented using one or more of the physical components shown in FIG. 3. Additionally, or in the alternative, various logical components may be implemented as software modules stored in the memory 306 and/or storage device 310 and executed by the CPU 312.
  • [0109]
    In one configuration, a plurality of PIOs 502 a-f may be stored within a memory, such as a memory 306 of an STB 102. A display component 702 displays each visual indicator 508 of a PIO 502 on a television 104 or other display device. The visual indicators 508 may be displayed in connection with a GUI 704.
  • [0110]
    In certain embodiments, the displayed visual indicators 508 a-f may be grouped in the GUI 704 within logical folders or the like, allowing user to organize the visual indicators 508 a-f in any desired manner. For example, a user may group visual indicators 508 a-f within such folders as “My sit-coms”, “My TV dramas”, “My sports”, etc., to facilitate easy access thereto.
  • [0111]
    As described more fully below, a selection component 706 allows a user to select one or more PIOs 502 by selecting corresponding visual indicators 508. Thereafter, the selection component 706 allows a user to choose one of the actions associated with the selected PIO 502. The selection of an action 504 may be accomplished via a context-sensitive menu or other suitable mechanism, as illustrated below.
  • [0112]
    As an example, suppose a PIO 502 a includes a number of attributes 506, such as a title attribute 506 a (e.g., “Dallas v. Denver”), a channel attribute 506 c (“4 KTVX”), a start time attribute 506 e (e.g., “Monday, 7:00 pm”), and an end time attribute 506 f (“Monday, 10:00 pm”). Further, suppose that the PIO 502 a includes a record action 504 a, a display action 504 b, and an iconic visual indicator 508 a.
  • [0113]
    [0113]FIG. 8 illustrates an exemplary GUI 704 including visual indicators 508 a-f corresponding to the PIOs 502 a-f of FIG. 7. In the illustrated embodiment, a user selects visual indicator 508 a using, for example, the arrow buttons 208-214 of the remote control 106. A pointer, selection outline, or other mechanism may be used to pick the desired indicator 508 a.
  • [0114]
    In response to the selection, a context-sensitive menu 802 may be displayed listing the available actions 504 a-b for the PIO 502 a. Where a large number of actions 504 are available, the menu 802 may display only the most popular or common actions 504, while providing a mechanism to display additional actions if desired.
  • [0115]
    In some cases, selecting an action 504 may result in the display of various options 804 in the form of a sub-menu 806. The options 804 may correspond to various parameters, features, or settings used by the corresponding action 504. For example, the record action 504 a may include two options 804 a-b, corresponding to record “Weekly” and record “Next Time Broadcast.” If the “Next Time Broadcast” option 804 b is selected, for instance, the record action 504 a may record the next episode of a television program, as opposed to recurring weekly episodes (in the case of TV drama or sit-com).
  • [0116]
    Of course, different selection mechanisms may be provided other than the context-sensitive menu 802 and sub-menu 806. For example, the selection component 706 may display a plurality of user-selectable icons (not shown) corresponding to different actions 504 and options 804.
  • [0117]
    Because each PIO 502 may be tailored to a particular television program, the actions 504 available in the context-sensitive menu 802 may vary from program to program. Similarly, options 804 available in a sub-menu 806 for a particular action 504 may vary from one program to the next.
  • [0118]
    Referring to FIG. 9, the STB 102 may further include an action component 902 that executes a user-selected action 504. The action component 902 may be implemented, in various embodiments, in the context of a Java Virtual Machine (JVM), a DCOM server, XML processor, or the like. Of course, other implementations are possible.
  • [0119]
    To execute the selected action 504, the action component 902 may interact with various other logical components of the STB 102, such as a recording component 904, a scheduling component 906, and a playback component 908, as described below.
  • [0120]
    Briefly, the recording component 904 is configured to record a television program using, for example, the storage device 310. The scheduling component 906 schedules recording tasks to record television programs to be broadcast in the future. In addition, the scheduling component 906 interacts with the recording component 904 to record a desired television program at the correct time and date in accordance with a scheduled recording task. The playback component 908 is configured, in one embodiment, to display a television program stored within the storage device 310 or the like. Each of the above-described components may be implemented in the context of a digital video recording (DVR) system, one example of which is TiVo®, available from TiVo, Inc.
  • [0121]
    Suppose, as shown in FIG. 8, that a user selects the record action 504 a with the “Next Time Broadcast” option 804 b. In response to such selection, and as illustrated in FIG. 10, the starting time 506 e, ending time 506 f, and channel 506 c attributes may be provided to the scheduling component 906. Thereafter, the scheduling component 906 schedules a recording event to record the television program. At the specified time and date, the scheduling component 906 instructs the recording component 904 to record the television program on the specified channel.
  • [0122]
    The recorded television program may be stored within the storage device 310 of the STB 102 or another suitable location. After the program is recorded, the stored location of the television program may be placed in the storage location attribute 506 m of the PIO 502 a to allow subsequent access thereto.
  • [0123]
    [0123]FIG. 11 illustrates use of PIOs 502 in the context of a personal information manager (PIM) 1100, such as an adapted version of Microsoft® Outlook®. In one embodiment, when a television program represented by a PIO 502 is scheduled for recording, the scheduling component 906 interacts with the PIM 1100 to display a visual indicator 508 of the PIO 502 in a calendar, to-do list, or the like, provided by the PIM 1100.
  • [0124]
    Moreover, in one implementation, the scheduling component 906 inserts reminders 1102 into the PIM 1100 to notify users concerning scheduled recordings. Similarly, reminders 1102 of upcoming television programs may be noted on the calendar a day or two prior to the broadcast date. In this manner, a user may quickly see which television programs he or she plans to watch.
  • [0125]
    In certain embodiments, PIOs 502 may be dragged and dropped onto the PIM 1100 using object linking and embedding (OLE), DCOM, ActiveX, or the like. A result of dropping a PIO 502 on the PIM 1100 may be to schedule the program represented by the PIO 502 for recording.
  • [0126]
    While FIG. 11 illustrates use of PIOs 502 in a PIM 1100, the object-oriented nature of the PIOs 502 allows them to interface with a variety of software applications. Moreover, PIOs may be used with a variety of electronic devices, including personal computers, cell phones, personal digital assistants (PDAs), pagers, telephones, and the like. The portable nature of the PIOs 502 and flexibility available provide for a variety of uses for the PIOs 502. For example, an action 504 may exist to call a user and deliver a voice synthesized reminder 1102 one hour prior to a broadcast of the associated television program. The possibilities for actions 504 are endless.
  • [0127]
    As shown in FIG. 12, once a television program is recorded, it may be retrieved and displayed in response to a user selection of the display action 504 b shown in FIG. 8. In one embodiment, the location of the recorded television program is retrieved from the stored location attribute 506 m and provided to the playback component 908. Thereafter, the playback component 908 retrieves the recorded program and plays back the same on the television 104.
  • [0128]
    As shown in FIG. 13, an action 504 d may be provided for displaying one or more of the attributes of a PIO 502. The action 504 d and the desired attribute(s) 506 may be selected using the context-sensitive menu 802 and sub-menu 806 illustrated in FIG. 8, although the invention is not limited in this respect.
  • [0129]
    Suppose, for example, that a user selects the display attribute action 504 d with the description attribute 506 b. In one embodiment, the description attribute 506 b is retrieved from the PIO 502 and provided to the display component 702 or the like for display. In various embodiments, a selected attribute 506 may include text, audio, video, or the like. Thus, the various modules not shown but well known in the art may be required for displaying or playing back the selected attribute 506.
  • [0130]
    [0130]FIG. 14 illustrates an embodiment of a system 1400 providing a set of PIOs 502 to an interactive television system 200. PIOs 502 may be available from a variety of sources including, for example, a broadcast center 110, a television source 114 (such as a television network), a PIO server (not shown), and the like. The PIOs 502 may be transmitted from these sources, across a network 101, the Internet 112, or other network connection, including a satellite link, to an STB 102. Of course, various types of networks 101 may be used, such as intranets, internets, HPNA networks, home RF networks, cable networks, etc.
  • [0131]
    In the depicted embodiment, a population component 914 is provided for populating an STB 102 or the like with a user-selected set of PIOs 502. The population component 914 may be implemented within the STB 102 (as shown), within a broadcast center 110, or the like.
  • [0132]
    In one embodiment, the population component 914 provides a filter component 1402 for reducing an initial set 1404 of available PIOs 502 to a user-specified set 1405 that may be stored within the STB 102. In certain embodiments, the initial set 1404 may include hundreds or thousands of PIOs 502 associated with corresponding television programs. Thus, reducing the initial set 1404 to a more manageable set 1405 is generally desirable.
  • [0133]
    The filter component 1402 may include or be associated with filtering criteria 1406. The filtering criteria 1406 may comprise a set of user-defined rules for filtering the initial set 1404. For example, a user may specify that the population component 914 only retrieve PIOs 502 having a start time 506 e of 7:00 pm or an end time 506 f of 10:00 pm (e.g., primetime). Alternatively, a user may specify that the population component 914 only retrieve PIOs 502 corresponding to sporting events. Of course, those skilled in the art recognize that various other filtering criteria 1406 may be used, including logical operators (e.g., AND, OR, NOT) and the like.
  • [0134]
    The filtering component 1402 may also be used within an STB 102 to divide the initial set 1404 based on different criteria, such as the genres of the respective television programs, in order to transmit PIOs 502 or information from PIOs 502 to auxiliary devices such as pagers, PDAs, personal computers, or telephone handsets that can receive information and display it for the user.
  • [0135]
    As illustrated in FIG. 14, suppose PIOs 502 a-d belong to the initial set 1404. The population component 914 applies the filtering criteria 1406 (e.g., primetime) to each PIO 502 a-d. The PIOs 502 that match the filtering criteria 1406 (e.g., PIO 502 a-b) are retrieved from the source and stored in the STB 102. As previously described, the display component 702 may then display the corresponding visual indicators 508 a-b on the television 104.
  • [0136]
    The filtering component 1402 may also be used internally within a STB 102 to organize the selected set 1405. For example, a user may further divide the set 1405 based on different criteria 1406, such as the genres of the respective television programs. This allows the user to organize the PIOs 502 using logical folders or the like.
  • [0137]
    FIGS. 15-24 are high-level block diagrams illustrating various techniques for sharing program information between entertainment devices using PIOs 502. While STBs 102 are used as particular examples of entertainment devices, the invention is not limited to STBs 102 or interactive television systems 200 generally. As used herein, an entertainment device may include any electronic device that is capable of receiving, storing, transmitting, or using PIOs 502.
  • [0138]
    As shown in FIG. 15, PIOs 502 may be transmitted between entertainment devices. For example, a first STB 102 a may store a plurality of PIOs 502 a-f. As described in greater detail below, a user may select a PIO 502 a for transmission to a second STB 102 b. In one embodiment, the PIO 502 a is transmitted through one or more broadcast centers 110 and the network 101 to the second STB 102 b, although other types of transmission are possible.
  • [0139]
    The process of selecting a PIO 502 a for transmission is further detailed in FIG. 16. As depicted, a user of the first STB 102 a may select a visual indicator 508 a corresponding to the PIO 502 a, which may be displayed in a graphical user interface (GUI) 1602.
  • [0140]
    Selection of the visual indicator 508 a may result in a context-sensitive menu 802 being displayed, listing various actions 504 that may be performed with respect to the PIO 502. For instance, as shown in FIG. 16, listed actions may include a send action 504 f and a record action 504 a. Thereafter, the user may select, for example, the send action 504 f from a context-sensitive menu 802.
  • [0141]
    In one embodiment, selecting the send action 504 f results in a sub-menu 806 being displayed, which lists various transmission options such as a “Network” option 804 c and a “Wireless” option 804 d. Choosing the “Network” option 804 c on the sub-menu 806 may result in the PIO 502 a being transmitted to the second STB 102 b via the network 101 using standard network protocols, such TCP/IP, UDP/IP, etc. In certain embodiments, the selected PIO 502 a may be attached to an email message and sent to a user of the second STB 102 b over the network 101 using the Simple Mail Transfer Protocol (SMTP) or other e-mail protocols.
  • [0142]
    Once a PIO 502 is selected for transmission, a user may designate a destination device for receiving the selected PIO 502. In one configuration, a user may indicate, for example, a name of the recipient, a personal network address of the recipient, a network address of the recipient's device, etc.
  • [0143]
    For example, in the depicted embodiment, a window 1604 may include a drop-down selection list 1606 for selecting a name of a recipient. Of course, the name may be associated with a network address that is not displayed. In response to the selection, the STB 102 a may send a copy of the PIO 502 a to “Robert Johnson” at the associated network address. If the PIO 502 a is being sent as an attachment to an email message, the STB 102 a may create the email message (not shown), attach the PIO 502 a to the message (using MIME or other similar techniques), and address the email message to “Robert Johnson.”
  • [0144]
    As shown in FIG. 17, other types of entertainment devices, such as personal digital assistants (PDAs) 1702 are illustrated. Of course, those skilled in the art will recognize that PIOs 502 may also be transmitted between an STB 102 and a PDA 1702, and between other devices, such as personal computers, cellular phones, pagers, webpads, and the like.
  • [0145]
    In such embodiments, different transmission methods may be appropriate. For example, a user may select a “Wireless” option 804 d from the sub-menu 806. Thereafter, the selected PIO 502 a may be transmitted from a first PDA 1702 a to a second PDA 1702 b using a wireless transmission method. Various transmission mediums may be used, such as infrared (IR) or radio frequency (RF). Of course, multiple PDAs 1702 within range of the transmitting PDA 1702 a may simultaneously receive a copy of the PIO 502 a.
  • [0146]
    In another embodiment, as shown in FIG. 18, a source STB 102 a (or other entertainment device, broadcast center 110, PIO server, or the like) transmits selected PIOs 502 to a destination STB 102 b based on a request 1802 from the destination STB 102 b. In certain configurations, the request 1802 includes search criteria 1804 relating to one or more attributes 506. For instance, the search criteria 1804 may select only those PIOs 502 having a “Sports” classification attribute 506 i. Of course, the criteria 1804 may relate to a plurality of actions 504 and attributes 506, and may include logical operators.
  • [0147]
    As depicted, the source STB 102 a then searches the PIOs 502 a-f for ones satisfying the criteria 1804. The PIOs 502 satisfying the criteria 1804, such as PIO 502 a, are transmitted to the destination STB 102 b via the network 101 as discussed with reference to FIG. 15.
  • [0148]
    In another embodiment, as illustrated in FIG. 19, a broadcast center 110 broadcasts a television signal 1902 from a television source 114 to one or more STBs 102 b. In addition, the broadcast center 110 may store a number of PIOs related to various television programs.
  • [0149]
    In one embodiment, the broadcast center 110 transmits PIOs 502 to the STBs 102 b based on the particular television signal 1902 being currently broadcast. For example, during a commercial for a televised football game, the broadcast center 110 may transmit a PIO 502 a representing the game. The PIO 502 a may include a record action 504 a, which records the game when selected.
  • [0150]
    The user may be notified of the PIO 502 a by a conventional trigger 1904 received with the television signal 1902, such as an ATVEF trigger. In particular, a user may be notified by the trigger 1904 that he or she can schedule football game for recording by selecting the record action 504 a.
  • [0151]
    Of course, PIOs 502 may be sent to the STB 102 for a wide variety of purposes beyond simply recording a program. For example, PIOs 502 may be transmitted to allow a user to purchase an advertised product, obtain supplemental information about a television broadcast, etc.
  • [0152]
    In other embodiments, as shown in FIG. 20, the broadcast center 110 may broadcast specific PIOs 502 to STBs 102 c-d based on demographic data 2002. The demographic data 2002 may indicate particular interests of users of STBs 102 c-d receiving television broadcasts from the broadcast center 110. For example, demographic data 2002 for “user 1” may indicate that he or she generally views sports programs. Consequently, the broadcast center 110 transmits the PIO 502 a related to a sports program to “user 1.” Similarly, PIO 502 e may be transmitted to “user 2” based on demographic data 2002 indicating that “user 2” generally views “Reality TV” programs.
  • [0153]
    As illustrated in FIG. 21, the broadcast center 110 may transmit PIOs 502 to an STB 102 b based on user preferences 2102. The preferences 2102 may be specified using conventional techniques (e.g., web, e-mail), and may be stored in a storage device 310 accessible to the broadcast center 110.
  • [0154]
    In one embodiment, the user preferences 2102 indicate the kinds of PIOs 502 that the user would like to receive. For example, the user may express preferences 2102 for PIOs 502 having a classification attribute 506 i of either “‘Sports’ OR ‘Reality TV’.” Accordingly, as depicted in FIG. 21, the broadcast center 110 transmits PIO 502 a and PIO 502 e to the STB 102 b which satisfy the preferences 2102. The broadcast center 110 may transmit the PIOs 502 satisfying the preferences 2102 periodically as new PIOs 502 are received by the broadcast center 110.
  • [0155]
    In another embodiment, a user of the destination entertainment device, e.g. STB 102 b, may automatically or manually screen PIOs 502 received by the device. For example, the user may not wish to receive PIOs 502 related to adult programs. Accordingly, the user may define a filter to automatically reject such PIOs 502. Alternatively, or in addition, the user may manually accept or reject each PIO 502.
  • [0156]
    In alternative embodiments, a PIO 502 may be communicated through the use of portable computer-readable media, such as CD-ROMs, diskettes, memory cards, memory sticks, and the like. For example, a PIO 502 may be copied or moved onto a computer-readable medium by a source device. Thereafter, the computer-readable medium is transported to a destination device, where it is loaded or read into memory 306 and/or a storage device 310 within the destination device.
  • [0157]
    As shown in FIG. 22, a destination device may include a graphical user interface (GUI) 2200 for organizing PIOs 502. The GUI 2200 may display a plurality of folders 2202 a-e, which correspond to logical folders (e.g., directories) or other similar mechanisms within the storage device 310. The displayed folders 2202 a-e may be organized into a folder hierarchy 2204, which mirrors a corresponding hierarchy of logical folders within the storage device 310.
  • [0158]
    Each of the displayed folders 2202 a-e may be given descriptive names, such as “Sports”, “Drama”, “Action”, etc. Of course, each displayed folder 2202 a-e may include one or more sub-folders (not shown).
  • [0159]
    In certain embodiments, each user may have a separate folder hierarchy 2204. For example, a root node 2206 corresponding to a particular user, e.g., “Susan”, may form the root of a particular hierarchy 2204. In other embodiments, a user's folder hierarchy 2204 may form a branch of a larger folder hierarchy 2204 for the device.
  • [0160]
    In one implementation, visual indicators 508 corresponding to newly received PIOs 502 are displayed in a “Received PIOs” panel 2208. A user may select a particular visual indicator 508 a and move the visual indicator 508 a to one of the displayed folders 2202 a. This may be accomplished, for example, using a drag-and-drop operation or other similar technique. In one configuration, the corresponding PIO 502 is moved to the correct logical folder. Later, as shown in FIG. 23, user may select the folder 2202 a to display the visual indicator(s) 508 associated with the folder 2202 a.
  • [0161]
    In certain embodiments, received PIOs 502 may be automatically associated with a folder 2202 based on one or more attributes 506. For example, folders 2202 a-e may be defined based on the classification attribute 506 i. Therefore, a PIO 502 a having a classification attribute 506 i of “sports” may be automatically stored within folder 2202 a.
  • [0162]
    Moreover, in certain implementations, when a PIO 502 is received, one or more actions 504 of the PIO 502 may be automatically executed by the destination system. For example, a record action 504 a or a display action 504 b of a PIO 502 may be configured to automatically execute when the PIO 502 is received by a STB 102 b. Such actions 504 a-b may be pre-selected by a producer or other user of a source system.
  • [0163]
    Based on the foregoing, the present invention offers a number of advantages not available in conventional approaches. The present invention allows users to quickly and efficiently access television programming within an entertainment system without the need for a conventional, grid-based EPG 402. PIOs 502 may be organized according to user-specified criteria and transmitted between various types of entertainment systems and devices.
  • [0164]
