Description

Explore via ATSC 3.0 display with mobility aids

This invention relates to ATSC 3.0 receivers and, in particular, to a method of automatically pairing an auxiliary device with an ATSC 3.0 receiver.

In multicast and broadcast applications, data is transmitted from a server to multiple receivers via a wired and/or wireless network. As used herein, a multicast system is one in which a server simultaneously transmits the same data to one of a plurality of receivers, wherein the receiver forms a subset of all of the receivers of at most all of the receivers. A broadcast system is one in which a server transmits the same data to one of all receiver systems simultaneously. That is, one of the defined multicast systems can include a broadcast system.

This section is intended to introduce the reader to various aspects of the technology, which may be related to the current embodiments described below. This discussion is believed to be helpful to provide the reader with background information to facilitate a better understanding of the various aspects of the invention. Accordingly, it should be understood that such statements will be read accordingly.

It would be advantageous to have a method of automatically pairing a primary ATSC 3.0 device with an auxiliary device such as a tablet or mobile phone. This is especially true if the premise has multiple ATSC 3.0 receivers and multiple auxiliary devices. Conventionally, pairing is typically accomplished by having the user manually select one of the device listings available on the network.

The next generation TV standard is currently being developed as ATSC 3.0. This standard includes the ability to communicate between a primary device, such as a TV, and an auxiliary screen, such as a mobile phone or tablet. The new ATSC 3.0 standard also mandates that ATSC 3.0 receivers have network connectivity. One use of the secondary screen can be to display things such as athletic event statistics, while the primary event is displayed on the TV. In order to use the auxiliary screen, the auxiliary device (second screen device) must try to pair with the TV so that the auxiliary device knows what is being played on the main screen. It is expected that when a person (a user, an observer) wishes to use an auxiliary device, the user will connect the auxiliary device to the local area network on which the primary device is located. If there is only one primary ATSC 3.0 device, it would be easy to simply match its network location to this device. However, there may be several major devices on the local network (for example, several ATSC 3.0 TVs in a home). A method of pairing an auxiliary device would be to list all the major devices on the network and have the user select the device, the user wishing to pair a particular auxiliary device with the device. However, it may be difficult for a user to know which listed device is the device with which it wishes to pair its auxiliary device. Another method would be to place a watermark in the content being played by the primary device. The auxiliary device can then detect the watermark and be able to identify the content being displayed. This can be problematic because it requires a large amount of content to be printed as a watermark. In this case, effectively all content will have to be watermarked, since it is not known in advance whether a user with one of the auxiliary devices will enter the room and wish to pair the auxiliary device with the ATSC 3.0 receiver. Again, some locally generated content (eg, a program guide) can be displayed that is not printed with a watermark. An ATSC 3.0 receiver is one of the broadcast receivers with network access.

A method and ancillary apparatus for pairing with a broadcast receiver having a network access, comprising: polling a regional network for a broadcast receiver having network access; determining whether more than one broadcast reception exists If there is only one broadcast receiver with network access, pair the auxiliary device with the positioned broadcast receiver with network access; direct a user to point the camera of one of the auxiliary devices with network access One of the calibrated broadcasts One of the screens is pressed and one of the auxiliary devices is pressed; the broadcast receiver having the network access is displayed to display its type; the screen of the target broadcast receiver having the network access is scanned; and the network memory is determined to be present. Whether a type is detected on the screen of the target broadcast receiver; and if the type is detected on the broadcast receiver with network access, the auxiliary device and the target receiving broadcast with network access are received. Pairing.

Although the proposed method is described in terms of an ATSC 3.0 receiver, it is not so limited, and any broadcast receiver (e.g., TV) having a network interface is contemplated to benefit from one of the proposed methods.

Accordingly, any component that provides such functionality is considered equivalent to the components shown herein.

Pairing a method of one of the main devices and one of the auxiliary devices uses a visual method law. In the proposed method, the primary device displays a known pattern on a screen for only a few frames (a small portion of the screen or the entire screen). The display of the frame will be fast enough that it will not be too fragmented so that people cannot watch the program, but will have sufficient duration for the auxiliary device to detect the pattern. Frames may be periodically or sequentially propagated with existing program frames. For example, if there are three primary ATSC 3.0 receivers, each of the ATSC 3.0 receivers will display a unique pattern at the request of the secondary device. The accessory user will point the device camera at the desired ATSC 3.0 receiver and capture the type of display. The accessory can then associate it with a particular network address detection pattern and thus can pair with the ATSC 3.0 receiver.

The proposed method provides a method of pairing an ATSC 3.0 receiver (which is a primary device, such as a TV) with an auxiliary device, such as a cellular phone or tablet. The method includes the following steps.

1. The auxiliary device polls the local area network for any primary device, the primary device being the ATSC 3.0 receiver.

2. If there is only one primary device, it is selected and the program stops.

3. If more than one primary device is present, the user of the accessory device is required to point the device camera at the display and pair it with one of the displays.

4. Next, the auxiliary device commands the primary device (eg, an ATSC 3.0 receiver) that the secondary device desires to pair with to display a pattern for many of the frames.

5. The auxiliary device begins to capture the main display through its camera and find a specific pattern. The pattern will be chosen to minimize the visual interference it will cause to an observer. This pattern can, for example, be positioned in only one corner of the screen, or it can be a simple additional but low level known background noise signal. In any case, the pattern can be simple, because the only information pattern that needs to be detected is present (displayed).

6. When the auxiliary device detects the pattern, the auxiliary device then sends a signal to the primary device to confirm the pairing.

In an alternate embodiment, if the accessory polls the local area network and there are multiple primary devices that are ATSC 3.0 receivers, the secondary device can trigger all of the primary devices of the ATSC 3.0 receiver to display a type. This can be done sequentially (ie, one pattern is displayed on the TV 1, then on the TV 2, etc., or different patterns can be displayed on the TV 1, TV 2, etc., but simultaneously). The auxiliary device will determine the specific type detected by the auxiliary device according to the use of multiple patterns, or the time when the type is detected using only one type to determine which of the main devices is to be paired. .

The pattern can be displayed for detecting any number of frames required. The pattern display can be used for one frame or multiple frames. The frames can be in sequence or spaced apart. In any event, the second screen device signals the primary (primary) device to display a pattern and then captures the pattern by an auxiliary device (second screen) camera. The fewer the frames, the better the interference can be minimized.

The displayed type can be a QR code. The type is displayed only on request (command) (regardless of the type). The pattern can be constructed to incorporate the existing video content being played so that one will not be aware of the pattern as it is being displayed.

1 is a flow chart of one exemplary embodiment of a proposed method for pairing an auxiliary device (second screen) with a primary device (ATSC 3.0 receiver). At 105, the accessory polls the local area network for the ATSC 3.0 receiver. At 110, it is determined if more than one ATSC 3.0 receiver is available. If only one ATSC 3.0 receiver is available, then at 115, the secondary device (second screen) is paired with an available ATSC 3.0 receiver. If more than one ATSC 3.0 receiver is available, then at 120, the accessory guides the user to point the camera of the secondary device (second screen) to the screen of the target (desired) ATSC 3.0 receiver and presses a button (such as an auxiliary device) Record key on). The accessory also directs the ATSC 3.0 receiver to display its type via its network connection. At 125, the auxiliary device scans the display (screen) of the target (desired) ATSC 3.0 receiver. At 130, the auxiliary device (second screen) determines if a pairing pattern has been detected. If a paired pattern has been detected, then at 135 At this point, the auxiliary device (second screen) pairs itself with the target device. The auxiliary device is associated with it in a specific network address detection format and is therefore capable of pairing with an ATSC 3.0 receiver. After 115 or 135, the program ends. If the auxiliary device (second screen) is not capable of detecting (associating) a paired pattern, then at 140 a timer is checked to determine if the time limit for detection has passed. If the detection time limit has not passed, the program proceeds to 125. If the detection time limit has elapsed, the program ends.

2 is a block diagram of one exemplary embodiment of an auxiliary device (second screen) proposed. The auxiliary device (second screen) includes a communication interface that is in two-way communication with the camera and with the processor. The camera is in two-way communication with the processor. The processor is in two-way communication with at least one storage area. If there is more than one storage area, one storage area can be used for data and a second storage area can be used to store instructions to direct the operation of the processor. The processor also includes (not shown) a timer. The communication interface of the auxiliary device polls the regional network for one of the broadcast receivers with network access. The processor determines if there is more than one broadcast receiver with network access, and if there is only one broadcast receiver with network access, the auxiliary device is paired with the positioned broadcast receiver with network access. The processor directs a user to point the camera of one of the auxiliary devices to a screen having one of the networked accesses to the broadcast receiver and to direct the user to press one of the auxiliary devices. The processor of the auxiliary device also directs the broadcast receiver with network access to display its type. The camera scans one of the target broadcast receivers with network access. The processor determines whether a type is detected on the screen of the target broadcast receiver having the network access, and if the pattern is detected on the broadcast receiver having the network access, the auxiliary device has Target broadcast receiver pairing for network access. If no pattern is detected on the broadcast receiver with network access, the processor determines if a timer has expired. The camera stops scanning if the timer has expired.
