Definitions

  • the present invention relates to ATSC 3.0 receivers and, in particular, to a method to automatically pair a secondary device with the ATSC 3.0 receiver.
  • a multicast system as used herein is a system in which a server transmits the same data to multiple receivers simultaneously, where the receivers form a subset of all the receivers up to and including all of the receivers.
  • a broadcast system is a system in which a server transmits the same data to all of the receivers simultaneously. That is, a multicast system by definition can include a broadcast system.
  • the next generation TV standard is currently being developed as ATSC 3.0.
  • This standard includes the capability to communicate between a main device such as a TV and a secondary screen such as a mobile phone or tablet.
  • the new ATSC 3.0 standard also mandates that the ATSC 3.0 receiver has network connectivity.
  • One use of the secondary screen could be to display such things as sporting event statistics while the main event is displayed on the TV.
  • the secondary device (second screen device) must somehow be paired with the TV so that secondary device knows what is playing on the main screen. It is expected that when someone (a user, a viewer) wants to use a secondary device, the user would connect the secondary device to the local area network on which the main device is located.
  • One method to pair a secondary device would be to list all of the main devices on the network and have the user select the device to which the user wants to pair a particular secondary device. However, it may be difficult for the user to know which of the listed devices is the device with which they want to pair their secondary device. Another method would be to put a watermark in the content which is being played by the main device. The secondary device could then detect the watermark and be able to identify the content that is being displayed. This may be problematic since is requires a large amount of content to be watermarked.
  • An ATSC 3.0 receiver is a broadcast receiver having network access.
  • a method and secondary device for pairing with a broadcast receiver having network access including polling a local area network for broadcast receivers having network access, determining if there is more than one broadcast receiver, pairing the secondary device with the located broadcast receiver having network access if there is only one broadcast receiver having network access, directing a user to point a camera of the secondary device at a screen of a targeted broadcast receiver having network access and to press a key of the secondary device, directing the broadcast receivers having network access to display their patterns, scanning screen of target broadcast receiver having network access, determining if a pattern was detected on the screen of the target broadcast receiver having network access and pairing the secondary device with the target broadcast receiver having network access, if the pattern was detected on the broadcast receiver having network access.
  • Fig. 1 is a flowchart of an exemplary embodiment of the proposed method for pairing a secondary device (second screen) with a main device (ATSC 3.0 receiver).
  • Fig. 2 is a block diagram of an exemplary embodiment of the proposed secondary device (second screen).

  • the disclosure as defined by such claims resides in the fact that the functionalities provided by the various recited means are combined and brought together in the manner which the claims call for. It is thus regarded that any means that can provide those functionalities are equivalent to those shown herein.
  • the proposed method to pair a main device and a secondary device is to use a visual method.
  • the main device displays a known pattern onto the screen (either a small portion of the screen or the entire screen) for only a few frames.
  • the display of the frames would be fast enough so that it would not be too disruptive to people watching the program, but would be of sufficient duration for the secondary device to detect the pattern.
  • the frames could be should sequentially or spread periodically with the existing program frames. For example, if there were three main ATSC 3.0 receivers, each of the ATSC 3.0 receivers would display a distinctive pattern at the request of the secondary device.
  • the secondary device user would point the devices camera at the desired ATSC 3.0 receiver and capture the pattern that was displayed. The secondary device could then correlate the pattern that it detected with a specific network address and therefore be able to pair with the ATSC 3.0 receiver.
  • the proposed method provides a method to pair an ATSC 3.0 receiver that is a main device such as a TV with a secondary device such as a cell phone or tablet.
  • the method includes the following steps.
  • the secondary device polls the local area network for any main devices that are ATSC 3.0 receivers.
  • the secondary device user is asked to point the device camera at the display with which a pairing is desired.
  • the secondary device then commands the main device (e.g., ATSC 3.0 receiver) with which the secondary device wants to be paired to display a pattern for a number of frames.
  • the main device e.g., ATSC 3.0 receiver
  • the secondary device starts to capture the main display through its camera and looks for a specific pattern.
  • the pattern would be selected so as to minimize the visual disturbance that it would cause to a viewer.
  • This pattern could, for instance, be located in only a corner of the screen, or it could be a simple additive but low level known background noise signal. In any case, the pattern can be can be simple since the only information that needs to be detected is whether the pattern exists (is displayed) or not. 6.)
  • the secondary device detects the pattern, then the secondary device sends a signal to the main device confirming the pairing.
  • the secondary device may trigger all of the main devices that are ATSC 3.0 receivers to display a pattern.
  • the secondary device would determine with which main device a pairing was desired either by the particular pattern the secondary device detected if multiple patterns were used, or by the time at which it detected the pattern if only one pattern was used.
  • the pattern may be displayed for any number of frames that was required for detection.
  • Pattern display may for one frame or multiple frames.
  • the frames may be in sequence or spaced apart.
  • the second screen device signals the primary (main) device to display a pattern, which is then captured by the secondary device (second screen) camera. The fewer the frames the better so as to minimize viewing interference.
