  • Another embodiment relates to a system for monitoring content display, which includes a first display device; a second display device; and a set top box coupled to the first and second display devices.
  • the set top box is configured for receiving a message from the second display device, and changing content display on the first display device based on the message.
  • FIG. 1 shows an example of a system architecture suitable for implementing embodiments of the present principles
  • FIG. 2 shows a view on a television screen during implementation of an embodiment of the present principles
  • FIG. 3 shows communications among different devices according to one embodiment of the present principles.
  • FIG. 4 shows an exemplary method 400 for performing content monitoring according to one embodiment of the present principles.
  • Embodiments of the present principles provide a system and method for dynamically monitoring, i.e., in real time, using a first display device, TV or broadcast content being displayed on a second display device. Both devices are operatively coupled to a set-top box (STB), such that one or more activities relating to broadcast content display on the second device, i.e., monitored device, will be reported to the STB.
  • STB set-top box
  • the STB is configured to respond to different reported activities by corresponding actions, including sending notifications or information alerts to the monitoring device (e.g., identifying the channel and/or program that the monitored device is tuned to), or causing content being displayed on the monitored device to be simultaneously displayed on the monitoring device, e.g., in Picture-in-Picture (PIP) mode.
  • PIP Picture-in-Picture
  • the information or content regarding the monitored activity is displayed on the monitoring device in a way so as not to significantly interfere with the viewing of a main program on the monitoring device.
  • the device whose activity or displayed content is being monitored is a portable device, and the monitoring device is a TV set.
  • the monitoring device is a TV set.
  • Such a system can be used by parents to monitor children's use of portable devices for TV watching activities in a home network environment. In general, however, monitoring can be done using any suitable display device for monitoring content being displayed on another display device in the same network, regardless of whether these devices are portable or not.
  • FIG. 1 shows a system architecture for implementing embodiments of the present principles, which allows broadcast channel content shown on one display device, e.g., a portable device such as a mobile phone, tablet, and so on, to be monitored from another display device such as a TV screen at a consumer premise or location.
  • a portable device such as a mobile phone, tablet, and so on
  • another display device such as a TV screen at a consumer premise or location.

  • programs from TV broadcasting companies 102 are transmitted by various content delivery mechanisms such as cable, terrestrial or satellites, to a set-top box (STB) 104.
  • Television or broadcast signals from one or more broadcasters 102 are decoded by the STB 104 and sent to a first display device 106, which may be a TV set or a portable device, either via wired or wireless connection.
  • the STB 104 includes at least a processor, two TV tuners and corresponding audio-visual (AV) output connections, which allow content on different broadcast channels to be received simultaneously and displayed on a single display device, or simultaneously on two different display devices.
  • AV audio-visual
  • the TV set or portable device (first display device 106 or a monitoring device) does not have a tuner. However, if there is already one tuner available on the first device 106 for showing the main screen content or program, then only one tuner would be needed on the STB to show PIP content for the purpose of practicing embodiments of the present principles.
  • Broadcast content can also be received directly by a second display device such as device 110, without going through the STB.
  • device 110 is a portable device, which can be any tablets, iPads or smart phones, equipped with a digital TV interface (or TV tuner) suitable for receiving broadcast signals, IP network connection and a screen for displaying TV or broadcast content.
  • the portable device 110 to be monitored for TV/broadcast activities also referred to as the monitored device
  • STB 104 are each configured for internet protocol (IP) network communications, with appropriate network cards, e.g., WiFi interface, with suitable software installed on device 110 to allow its TV or broadcast content activities to be monitored by the STB.
  • IP internet protocol
  • the portable device 110 is configured such that, upon receiving TV or broadcast content from any channel, an IP packet with the channel's identification information will be sent to the STB, as shown by the arrow (labeled with IP packet) in FIG. 1.
  • Information regarding subsequent activities on the portable device such as changing TV channel and terminating TV content display will also be encoded into different IP packets and sent to the STB.
  • the STB can also be configured to monitor a number of devices 110 at the same time. While the STB can simultaneously monitor or receive information regarding the content or channels for several devices, its ability to show video content in several PIP windows depends on the number of tuners in the STB. On the other hand, if the monitored information is shown only in ticker or text format (e.g., identification of channels and/or programs), the STB can provide multiple channel information to be displayed on the monitoring device at the same time.
  • ticker or text format e.g., identification of channels and/or programs
  • the STB 104 is capable of receiving IP packets from any portable device 110 for reporting the TV watching activities or content being displayed on the respective portable devices.
  • the embedded messages in the IP packets are extracted by the STB, which then tunes to the same channel as the portable device sending the "activity-reporting" IP packets.
  • Signals are sent from the STB 104 to the TV set (first display device or monitoring device 106) so that content currently displayed on the portable device 110 is also shown on the TV set 106 in picture (PIP) mode. If the TV or monitoring device 106 is in an idle or stand-by state, it can also be configured to be waken up by software in the STB 104.
  • the TV set 106 is capable of receiving video signals from the STB and rendering corresponding images to the viewers. It also offers a picture-in-picture (PIP) mode, which allows a picture to be compressed in vertical and horizontal directions, and displayed over a main picture.
  • PIP picture-in-picture
  • FIG. 2 shows an example with Program 1 being shown as the main picture on the

  • the channel for the main picture (Program 1) can be the same as, or different from, the channel showing Program 2 in the PIP picture.
  • the STB 104 can be configured to show the monitored content in PIP mode on the first display device 106 for a predetermined time duration.
  • the time duration can be set in advance using the STB, or the PIP mode display can also be terminated by a user manually.
  • the STB 104 and TV set 106 can be configured to provide multiple PIP areas for simultaneously showing content corresponding to different monitored devices 110, as long as there are sufficient number of tuners available on the STB 104 and TV or monitoring device 106. In other words, the number of allowable PIP windows depend on the total number of tuners available.
  • TV channels e.g., from different monitored devices
  • content from one monitored channel can be shown on the PIP window for a certain time duration, and the STB 104 can switch to another monitored channel for another time duration, and so on.
  • an alert message can be sent to the monitoring device to identify the channel and/or program being displayed on the monitored device. Since text information can be provided in a much smaller area than a PIP window, such an alert message can also be displayed in different formats or at other locations of the TV screen, e.g., similar to a ticker or banner, as shown in FIG. 2.

  • a second viewer e.g., a child, opens a TV-watching application on a tablet or other portable device, and selects a TV channel (see box 304).
  • the tablet or portable device corresponds to the device 110 of FIG. 1, i.e., a monitored device.
  • the TV- watching application on the tablet Upon selecting the TV channel and displaying the corresponding TV content, the TV- watching application on the tablet encapsulates an IP packet with a message indicating the start of TV content display with identification information (e.g., channel number, name or tuner frequency) of the selected channel.

  • the received video signals from the second tuner are decoded by the STB and sent to the TV set, for rendering the pictures or images corresponding to the channel of the second tuner in PIP mode on the TV screen (see box 308).
  • the STB can also send a notification message for display on the TV screen, to identify the channel, program and/or type of content being displayed on the tablet. Since the notification message can be shown as a ticker on the TV, it does not need to occupy as large an area as showing the actual content.
