Description

TECHNICAL FIELD

This application relates to the field of computing, and more particularly to a wireless display adapter device.

BACKGROUND

Wireless is currently an inevitable trend and lifestyle for everything. User demand is high to wirelessly play content from mobile devices such as laptops, tablets and phones, for both business and consumer usages. A number of screen mirroring or wireless display products are available, including TV boxes/dongles and streaming devices. However, these existing solutions all have their limitations and leave much to be desired for many usage scenarios. Accordingly, there is still a demand to develop a solution to share content anywhere quickly.

Existing solutions provide a number of pain points for a user to experience in order to share content, such as video. Pain points which users may be required to experience include: 1) For business users, the necessity to carry a number of converters/connectors, such as High-Definition Multimedia Interface (HDMI), DisplayPort (DP), Digital Visual Interface (DVI), Video Graphics Array (VGA), etc, for compatibility purposes. Different mobile devices may have different I/O ports, but compatible adapters may be missing in the presentation environment such as a conference room. Carrying a high number of dongles is troublesome and too many wires create clutter. 2) In the presentation environment such as a conference room, wires dictate the presenter's seat and require switching seats if there are multiple presenters. 3) Existing conference room infrastructures only assume presentations from laptops, limiting the usage of other mobile devices. 4) Plugging in and connecting to the A/V display device takes time away from the meeting. 5) WLAN access could be cumbersome or WiFi speed could be slow or unstable in some scenarios, so sharing or streaming will be limited if relying on WLAN connections, e.g. when meeting at client sites or staying at hotels.

Some existing wireless display devices may address some of these issues, but may require a painful process of searching, user identification and connection, which easily takes twenty seconds or more to accomplish.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

One or more embodiments described herein provide users with a fully contained wireless display experience without requiring extra plugs or dongles to be carried by a user for content presentations such as meeting room projector/flat panel, hotel room, family room HDTV entertainment presentations or any other desired presentation environment.

Various embodiment described herein provide for a wireless display adapter device having a compact, portable, self powered design to address one or more of the aforementioned pain points for users. One or more embodiments provides a clean and simple connection model having a power-on connection to a personal user device such as a smart phone, tablet computer, or laptop computer. In accordance with various embodiments, the wireless display adapter device and user device (laptop/tablet/phone, etc.) can initiate a connection between one another when powering up. In particular embodiments, the connection can be made before the wireless display adapter device is connected to a display device (such as a projector and/or television) which makes the perceived user experience instant (i.e. essentially a zero second connection). Various embodiments enable users to present and share content anywhere wirelessly and instantly. Particular embodiments may use Intel® Wireless Display (WiDi) and/or Pro-WiDi technology to connect between the wireless display adapter device and the display device.

In accordance with various embodiments, a wireless display adapter device includes (Intel® WiDi and Pro-WiDi technology) a battery and multiple connectors to provide users a fully contained wireless display experience (e.g., requiring no wall plugs or USB dongles) for providing content presentations such as meeting room projector presentations and hotel room or family room HDTV entertainment. In one or more embodiments, the wireless display adapter device is a personal device allowing a user to customize a home screen, device name and other settings. In one or more embodiments, the wireless display adapter device supports auto-discovery, instant connection, stable streaming and meeting management for multiple presenters. In one or more embodiments, the wireless display adapter device is designed with a slim and portable for factor enabling easy portability.

FIG. 1 illustrates an embodiment of a system 10 for streaming content from a user device 12 to a display device 14 using a wireless display adapter device 16. In the embodiment illustrated in FIG. 1, user device 12 and the wireless display adapter 16 are in communication via a wireless connection such as a Bluetooth Low Energy (BLE) connection, a Bluetooth connection, or a WiFi connection, and wireless display adapter device 16 is coupled to display device 14 via a wired connection such as an HDMI and/or VGA connection. In accordance with various embodiments, content (such as a video presentation) is streamed from the user device 12 via the wireless connection to wireless display adapter device 16, and wireless display adapter 16 outputs the streamed content received from the user device 12 to the display device 14 using the wired connection. In one or more embodiments, display device 14 may be configured to display the streamed content within a screen of the display device 14. In one or more embodiments, user device 12 may include a smart phone, a tablet computer, a laptop computer, a laptop computer, or any other suitable computing or communication device. In one or more embodiments, display device 14 may include a monitor, a television, a projector, or any other suitable display device.

FIG. 2 illustrates a first flow 20 showing establishment of a connection from user device 12 to wireless display adapter device 16. In the start of the flow in 22, wireless display adapter device 16 is in a sleep state/mode in which a Bluetooth Low Energy (BLE) advertising mode is enabled. In the BLE advertising mode, wireless display adapter device 16 periodically transmits a beacon signal including advertising information which may include a BLE ID associated with wireless display adapter device 16. In 24, user device 12 initiates a WiDi connect operation. WiDi is a technology that allows streaming of video and other content from a user device to a display. In 26, user device 12 uses a BLE scan operation to discover the wireless display adapter device 16 by receiving the beacon signal transmitted from wireless display adapter 16. In 28, user device 12 determines whether the BLE ID received in the beacon signal matches a BLE ID associated with the wireless display adapter device 16. If the BLE ID does not match, in 30 the user device 12 initiates a legacy WiDi scan and connect process. If the BLE ID matches, in 32, user device 12 connects to wireless display adapter device 16 using a BLE connection request to initiate wake up of wireless display adapter device 16 from the sleep mode to an active mode. In 34, wireless display adapter device 16 wakes up in response to the BLE connection request. In particular embodiments, this process can be performed in less than 500 ms depending on the advertisement frequency (typically 100 ms to 1 s). Although the embodiment illustrated in FIG. 2 is shown as using a BLE beacon to facilitate discovery of the wireless display adapter device 16 via the user device 12, it should be understood that in other embodiments any type of wireless connection may be used.

As further illustrated in FIG. 2, in 36, wireless display adapter device 16 initiates a WiDi connect procedure using a WiFi connection with user device 12 after powering up, and in 38 user device 12 is connected to wireless display adapter device 16 via the WiFi connection. In particular embodiments, this process may take approximately five seconds. Although the embodiment illustrated in FIG. 2 is shown as using a WiFi connection to facilitate streaming of content between the user device 12 and the wireless display adapter device 16, it should be understood that in other embodiments any type of wireless connection may be used.

In 40, the user may then establish a wired connection between wireless display adapter device 16 and display device 14 (such as a TV and/or projector). When the user finishes connecting the wireless display adapter device 16 to the display device 14, the output is ready and the user may begin immediately streaming content, such as video, from the user device 12 to the display device 14 via the wireless display adapter device 16. In 42, user device 42 begins wirelessly streaming content to wireless display adapter device 16. In 44, wireless display adapter device 16 streams the content received from user device 12 to display device 14 using the wired connection. It should be noted that in other embodiments that after BLE wakeup, a WiDi connection can be initiated from the user device 16. In particular embodiments, a “power good” message from the wireless display adapter device 16 over BLE may be used as a trigger mechanism (not shown) to initiate the connection.

FIG. 3 illustrates a second flow 50 showing an almost instant connection from the wireless display adapter device 16. A concern that may exist of initiating a WiDi session from wireless display adapter device 16 is that of privacy. Therefore, in accordance with various embodiments, the initial display may be an insensitive splash screen. Only after user acknowledgement on the user device, does the streaming start. In any case, the time consuming part of discovery and connecting is finished in the process and user perception is that of an almost instant experience, especially compared to existing streaming products. In the start of the flow in 52, wireless display adapter device 16 is in a sleep state/mode in which a BLE advertising mode is enabled. In 54, user device 12 is waiting for establishment of a connection with wireless display adapter device 16. In 56, wireless display adapter device 16 is connected to display device 14 (e.g., a TV/projector). In 58, wake up of the wireless display adapter device 16 is initiated. Upon wakeup of wireless display adapter device 16, wireless display adapter device 16 initiates a connection with user device 12 using a WiFi connection using a WiDi connection procedure in 60. In 62, user device 12 is WiDi connected to wireless display adapter device 16. In 64, wireless display adapter device 16 initially displays a splash screen in order to protect from any private information that may be currently displayed by the user device 12 until receiving a user acknowledgement from user device 12 in 66. In 68, content, such as video, is wirelessly streamed from user device 12 to wireless display adapter 16. In 70, the content received from user device 12 is then streamed to the display device 14.

In accordance with various embodiments, wireless display adapter device 16 is a self-powered portable adapter to place users in control of how they connect and share streaming content anywhere, and/or allow personalization of home screen, device name, and other settings. After a first time pairing, wireless display adapter device 16 can automatically recognize and connect to the user's paired user mobile device in one or more embodiments. Various embodiments allow users to move around the presentation environment (e.g., a room) freely without wire/power outlet constrains. One or more embodiments may provide for flexibility for all mobile devices to be used to present and stream content for both business/work and entertainment purposes. Some embodiments provide for users the ability to allow other people to connect to the wireless display adapter device and share content through a seamless switch.

In 100, wireless display adapter device 16 is connected to display device 14. In 102, wireless display adapter device 16 receives content from user device 12. In 104, wireless display adapter device 16 sends the content to display device 14.

In a particular embodiment, the beacon signal further includes include an identifier associated with wireless display adapter device. In still another particular embodiment, the beacon signal is a Bluetooth low energy signal. In another particular embodiment, the connection is a WiFi connection. In still another particular embodiment, the connection between the wireless display adapter device and the display device is a wired connection. In another particular embodiment, the wired connection is one or more of a High-Definition Multimedia Interface (HDMI) connection, a DisplayPort (DP) connection, a Digital Visual Interface (DVI), and a Video Graphics Array (VGA) connection.

Various embodiments may provide for a wireless display adapter device 16 that is highly integrated, compact and portable. One or more embodiments may provide users with a nearly instant connection with display screens in, for example, a conference, hotel or family room. One or more embodiments may support smooth and stable presentation/streaming without requiring a WLAN connection or bulky cables. One or more embodiments may be self-powered with a flat flexible USB charging cable for easy charge and carrying. One or more embodiments may offer a private screen before a user starts sharing content. In various embodiments, the wireless display adapter device 16 is provided as a personal device that only needs pairing once with user device 12 associated with a particular user such as a laptop, tablet and/or phone, and then can automatically connect to a favorite available device when it is powered on. More importantly, in various embodiments wireless display adapter device 16 can realize an instant connection, which hasn't been achieved by existing WiDi dongles or other display adapters. In one example implementation that realizes such instant connection: 1) the wireless display adapter device BLE is in advertisement mode which sends beacons periodically (e.g., once per second) when the system is off. In a particular embodiment, the average power drain is approximately 10 uA in this mode allowing a battery pack (e.g. a 2000 mAh battery pack) to provide a long batter life (e.g., more than 20 years of battery life). 2) the user device (e.g., laptop) starts an application (such as a WiDi app), which triggers the user device BLE connection to wireless display adapter device 16. The BLE connection initiates turning on of a main CPU of the wireless display adapter device 16 and initiates a WiFi connection between user device 12 and wireless display adapter device 16. 3) The user physically connects an output connection of wireless display adapter device 16 to an input of display device 12 and starts presenting content. Accordingly, content, such as a video presentation, is streamed from user device 12 to wireless display adapter device 16 using the WiFi connection between user device 12 and wireless display adapter device 16, and the wireless display adapter device 16 provides the content to display device 14 via the connection between wireless display adapter device 16 and display device 14. Display device 14 may then display the content streamed from user device 12 upon one or more screens of display device 14.

In particular embodiments, wireless display adapter device 16 has meeting management capability to allow other people to connect and share. In particular embodiments, a software application for use with wireless display adapter device 16 may be simple and elegant with a few options including a first-time set-up option, a personalize home screen option, device name option, “start sharing” option, “disconnect” option and “accept request” option to allow others to share. Particular embodiments may work across operating systems such as Windows and Android.

Various embodiments of wireless display adapter device 16 may include a host of unique design variations including:

1) Built-in connector choices can vary depending upon particular user scenarios in various embodiments. For example, if a major usage is to connect to a TV, a male HDMI output connector can be built into wireless display adapter device 16 instead of a female VGA output. In particular embodiments, to reduce the number of accessories in a product package or pouch, more connectors can be integrated into the design of wireless display adapter device 16.

2) The placement of built-in connectors can vary in various embodiments. The wireless display adapter device design shown in FIG. 4 has two connectors on two ends. For different form factors, in different embodiments two or more connectors if necessary can be placed on the same end or placed on two, three or four sides of the device.

3) The manner to build in connectors can vary in various embodiments. For example, in a particular embodiment a “dongle-on-dongle” design can be used to incorporate male-to-male HDMI and VGA into the wireless display adapter device. Specifically, a compact male-to-male HDMI or VGA converter can be plugged into the female HDMI connector or the VGA connector in FIG. 4 as part of the wireless display adapter device. If they are not needed, a user may unplug them to use the female ports; after usage, the user may then plug them back in. In addition, flat flexible cable can also be used to integrate extendable male HDMI into the wireless display adapter device. With such variations, the wireless display adapter device may function as a “Swiss army knife”, which is convenient to carry and works for all scenarios.

4) Various embodiments may provide for the combination of a battery bank and wireless display adapter device 16 providing both charging and wireless display functions to support two-way charging between mobile devices and the wireless display adapter device's own battery, which reduces the number of devices that users have to carry.

5) Add-on features. Various embodiments may provide for many add-on features to be included within the wireless display adapter device 16 such as a BLE beacon and/or a flashlight.

6) Charging options can vary in accordance with various embodiments. Besides USB charging, one or more embodiments may provide for wireless charging and/or powered HDMI (such as a Mobile High-Definition Link (MHL) connection) can also be used for charging.

Compared to existing solutions (e.g., screen mirroring or wireless display products), one or more embodiments of the wireless display adapter device described herein may provide unique advantages to deliver a better user experience.

1) Existing solutions usually require a password to enter the WLAN network or use of a discovery protocol (scan, confirm and connect) to connect a user device to the wireless display adapter device. This is time consuming, especially. in a densely deployed environment. One or more embodiments of wireless display adapter device 16 provide a personal device that can be connected to user device 12 when both devices power up. In fact, in one or more embodiments the connection can be made before wireless display adapter device 16 is connected to the display device 14 (e.g., a projector and/or television (TV)), which makes the perceived user experience nearly instant with zero perceptible connection time. In one or more embodiments, wireless display adapter device also 16 supports a legacy scan protocol for other users to join.

2) Some of the existing solutions require a WLAN connection, which could be cumbersome or slow in the use cases such as meeting in a customers' conference room or staying in a hotel. Various embodiments of the wireless display adapter device 16 do not need any WLAN connection, which enables users to present and share anywhere.

3) Since wireless display adapter device 16 is a battery powered device in one or more embodiments, wireless display adapter device 16 may incorporate unique features that existing solutions cannot provide. A few examples include: a) Bluetooth low energy (BLE) beacons incorporated in the wireless display adapter device can help to easily keep track of user's devices and even other valuables if they are together. It can remind users not to forget their devices after the users share or present; b) depending on the battery power capacity, the wireless display adapter device can also be used as a battery bank that allows two-way charging between phones and the wireless display adapter device. Such a combination design reduces the number of devices that users have to carry.

4) With existing solutions, business users may still need to carry dongles like male to female HDMI connectors, VGA convertors because the prevalent wireless display or screen mirroring devices only have a male HDMI port, which have to be converted before being plugged into the projector/TV cables in the conference rooms. One or more embodiments of the wireless display adapter device address this problem by incorporating female HDMI and VGA connectors in the wireless display adapter device to avoids user hassle.

5). Existing solutions require external power, and hence users have to carry and plug in accessories such as a USB dongle and an AC adapter. Wires and AC outlet location could put constrains on users. Various embodiments of the wireless display adapter device 16 are battery powered, which removes such constraints, frees users up and reduces their burdens of carrying power dongles as well as saving the time of connecting to a power source.
