This disclosure relates generally to automatic switching from one display connection (or interconnect) to another display connection (or interconnect).
A user may want to connect an electronic transmitting device to a receiving device in order to display content from the electronic device. These connections between a transmitting device and a receiving device can be wired or wireless in nature. Some devices can transmit one or more images to be displayed, and some devices can receive a transmission and then forward the transmission or display images in response to the transmission. Both transmitting and receiving devices can be enabled to connect using a variety of wired and wireless connection protocols.
The following detailed description may be better understood by referencing the accompanying drawings, which contain specific examples of numerous features of the disclosed subject matter.
In some cases, the same numbers are used throughout the disclosure and the figures to reference like components and features. In some cases, numbers in the 100 series refer to features originally found in
Extending or sharing a display of a device with another device via a wired and/or wireless communication interface can be a preferred usage model for a user. Transmitters and/or receivers of content can communicate via a wide range of wired and wireless communication protocols. When a device shares content using a wired interface, an interruption can occur of the transmission of the content between the transmitting device and the receiving device. This can cause an interruption in viewing of the receiving content on a display device. If the transmitting device and/or the receiving device need to unplug a wired connection, for example, delays in display of the content can be experienced. For example, this might occur if a receiving device includes a monitor with one display/charging port and the user wishes to charge another device in that port while still continuing to share content from an originally connected device.
In some embodiments, a display switching system can seamlessly switch from wired to wireless display. Users can continue viewing content on a display screen in an uninterrupted manner even if a primary transmitting device is disconnected from a wired interface for some reason. In some embodiments, policy management can choose a best available transport mechanism available for a backup connection in case a primary current connection link is interrupted, unplugged, etc.
In some embodiments, a display session can be instantaneously continued using a wireless connection when a wired connection link is disconnected (for example, unplugged). This can be implemented without any manual effort by a user. In some embodiments, a wireless connection can be set up in the background in a paused mode upon establishment of a wired connection. Content can be transmitted over the wired connection until it is disconnected for some reason. Upon disconnect of the wired connection, the wireless connection can be immediately un-paused without any setup time at that point involving, for example, negotiating a wireless connection, setting up a media pipeline, etc. before the wireless connection can begin showing content. According to some embodiments, the wireless connection is set up in advance so that those types of activities need not be done upon a sudden disconnect of the wired connection. For example, with a Miracast wireless connection, setting up the wireless connection at time of wired connection disconnect might take 7 to 10 seconds or so, resulting in content not being able to be displayed to a user during that time. However, in some embodiments, this 7 to 10 second delay need not occur since the wireless connection is set up around the time of initial wired connection and is waiting in a paused mode until occurrence of a disconnect of the wired connection. In some embodiments, an enhanced user experience can be provided since a backup connection (for example, a backup wireless connection) is implemented due to establishment of the backup connection upon a connection event of a link such as a wired link rather than being established upon a disconnection event of that link.
Some embodiments relate to automatic switching from one display connection (or interconnect) to another display connection (or interconnect). In some embodiments, upon disconnection of a wired display connection (or interconnect) between a transmitting device (for example, such as an electronic device and/or a computing device) and a receiving device (for example, such as a display device), a wireless connection (or interconnect) between the transmitting device and the receiving device that has been established in the background can be used to seamlessly connect the transmitting device and the receiving device in a manner that provides uninterrupted viewing of display content on the receiving device and/or on another device. This can be implemented without any interruption noticeable to one or more viewers of the content on a display device such as the receiving device and/or another device to which the receiving device transmits the content. In some embodiments, seamless switching from a first connection to a second connection can be implemented so that users can continue viewing content on a display screen when the first connection becomes disconnected. In some embodiments, seamless switching from a wired connection to a wireless connection can be implemented so that users can continue viewing content on a display screen when the wired connection becomes disconnected. In some embodiments, seamless switching from a wireless connection to a wired connection can be implemented so that users can continue viewing content on a display screen when the wireless connection becomes disconnected.
Computing device 102 and display device 104 can be coupled to each other via a wired interconnect 106 and/or via a wireless interconnect 108. In some embodiments, wired interconnect 106 can be, for example, a wired interconnect that can transmit data using a high-definition multimedia interface (HDMI) protocol, Thunderbolt protocol, DisplayPort protocol, Digital Visual Interface (DVI), Video Graphics Array (VGA), Display over USB (USB Display), and/or using some other wired protocol, communication link, and/or other wired communication methodology. In some embodiments, wireless interconnect 108 can be, for example, a wireless interconnect that can transmit data using Miracast, Wireless Gigabit Alliance (WiGig), Wireless Display (WiDi), WiFi, WiFi-Direct, Apple Airplay, Google Chromecast, and/or using some other wireless protocol, communication link, and/or other wireless communication methodology.
In some embodiments, computing device 102 can be referred to as a transmitter device (Tx), and display device 104 can be referred to as a receiver device (Rx). In some embodiments, computing device 102 and display device 104 can connect via wired interface 106 in order to share content (for example, in order for the computing device 102 to share content with the display device 104). Upon connection via the wired interface 106, the computing device 102 can also set up the wireless interface 108 with display device 104, with the wireless interface 108 running in the background. In this manner, computing device 102 can keep the wireless connection 108 as a backup so that a sharing session between the computing device 102 and the display device 104 that is occurring via wired connection 106 can continue in an uninterrupted fashion using the wireless connection 108 if the wired connection 106 is unplugged or disconnected for some reason. In some embodiments, this is implemented through a seamless switch from the wired connection 106 to the wireless connection 108 in order to continue the sharing session of the shared content between the computing device 102 and the display device 104.
In some embodiments, the backup connection on wireless interface 108 can be set up based on some cues. For example, in some embodiments, the backup connection via the wireless interface 108 can be set up in response to, for example, a hot plug event that is emitted when a connection is established between computing device 102 and display device 104 on wired connection 106. For example, when a transmitter such as computing device 102 connects to a receiver such as display device 104 via a wired connection 106 (for example, an HDMI connection), a wireless connection 108 (for example, a Miracast connection) can be automatically established between the transmitter computing device 102 and the receiver display device 104 in the background. The established wireless connection (Miracast connection) can be maintained in a paused state as long as the wired connection (HDIM connection) is alive. When the wired connection is ended due to an unplug of the wired connection 106, for example, the wireless connection is automatically un-paused (activated) and streaming continues from the transmitter computing device 102 to the receiver display device 104 via the wireless connection 108. In some embodiments, a user can toggle between setting up a backup wireless connection. In some embodiments, a user can input a preferred backup connection (for example, if an HDMI wired connection is being used as the wired connection, then a backup wireless Miracast connection is preferred by the user to be used upon disconnect of the HDMI wired connection, and/or if a DisplayPort wired connection is being used as the wired connection, then a backup wireless WiGig connection is preferred by the user to be used upon disconnect of the DisplayPort wired connection, etc.)
In some embodiments, device 102 is a transmitter device that can transmit content (for example, display content) and/or device 104 is a receiver device that can receive content (for example, display content). In some embodiments, device 102 can also be a receiver device (for example, device 102 can be a transceiver device that can transmit and receive content such as display content). In some embodiments, device 104 can also be a transmitter device (for example, device 104 can be a transceiver device that can transmit and receive content such as display content).
Display connection system 200 can include a number of drivers for various connection protocols. In some embodiments, the various connection protocols can be wired connection protocols. In some embodiments, the various connection protocols can be wireless connection protocols. In some embodiments, the various connection protocols can include both wired connection protocols and wireless connection protocols. The various wired connection protocols can include, for example, a high-definition multimedia interface (HDMI) protocol, Thunderbolt protocol, DisplayPort protocol, DVI, VGA, Display over USB (USB Display), and/or some other wired protocol, communication link, and/or other wired communication methodology. The various wireless protocols can include, for example, Miracast, WiGig, WiDi, WiFi, WiFi-Direct, Apple Airplay, Google Chromecast, and/or some other wireless protocol, communication link, and/or other wireless communication methodology.
Display connection system 200 can include, for example, wired connection drivers including an HDMI driver 212 and a DisplayPort driver 214. Display connection system 200 can include, for example, wireless connection drivers including WiGig driver 216 and WiFi/WiFi-Direct driver 218. While
User input device 202 represents any device and/or methodology of receiving user input. For example, user input device 202 can include any type of user interface (UI) and/or an application for user input. User input device 202 can include receiving user input via an input such as a touch screen or a keyboard. In some embodiments, user input device 202 includes a user level application with user interface (UI) through which a user of a device can configure a backup policy. For example, a user might configure a backup policy in which a Miracast wireless connection is identified as a backup connection protocol for an HDMI wired connection, and/or in which a WiGig wireless connection is identified as a backup connection protocol for a DisplayPort wired connection, etc. Backup policies input by the user via the user input device 202 are provided to backup policy manager 206.
Discovery manager 204 can discover backup interfaces available on a transmitting device and/or a receiving device (for example, on a peer device and/or on a display device). In some embodiments, discovery manager 204 can discover backup wireless interfaces available on a transmitting device and/or a receiving device. Discovery manager 204 can use a variety of different ways to determine a backup connection protocol, and can provide discovered backup interface protocols to backup policy manager 206.
Evaluation manager 208 can evaluate a current transport medium (for example, a current wired transport medium) in terms of stream types, codecs used, bandwidth required, frame-rate, etc. Evaluation manager 208 can provide the evaluated information to the backup policy manager 206, which can use that information to determine a best backup medium (for example, a best wireless backup medium) for the current transport medium (for example, a current wired transport medium).
Backup policy manager 206 can contain a policy to decide which interface (for example, which wireless interface) to use as a backup for a particular medium (for example, for a particular wired medium). Backup policy manager 206 can use inputs from the user via user input 202, from discovery manager 204, and/or from evaluation manager 208 to determine a best transport medium for another medium (for example, to determine a best wireless transport medium as backup for a particular wired medium). Backup policy manager 206 can also set a priority for backup mediums. For example, backup policy manager 206 can set a priority of WiGig over Miracast for 4k content in some embodiments. Backup policy manager 206 uses its settings, determinations, etc. to provide control to a variety of drivers for various protocols. For example, in some embodiments, backup manager controls HDMI driver 212, DisplayPort driver 214, WiGig driver 216 and WiFi/WiFi-Direct driver 218.
User input 202, discovery manager 204, backup policy manager 206 and evaluation manager 208 can be used in some embodiments to facilitate a seamless switching of display protocols (for example, in some embodiments to facilitate a seamless switching of a wired communication protocol interconnect to a wireless communication protocol interconnect).
In some embodiments, a user pairs in advance a transmitting device (for example, a computing device) with a receiving device (for example, a display device) using one or more communication protocols (for example, using one or more intended backup communication protocols). Since a first-time pairing can require some form of authentication, if a user pairs the transmitting device with the receiving device in advance using one or more intended backup communication protocols (and/or all intended backup communication protocols), an advance pairing by a user can ensure a more seamless transition to the backup communication protocol according to some embodiments. In some embodiments, a manufacturer such as, for example, an Original Equipment Manufacturer (OEM) might sell or bundle a transmitting device with a receiving device and pre-pair the devices using one or more backup communication protocols, which may avoid an advance pairing by the user.
At box 302 display connection switching 300 sets a connection backup policy. Box 304 determines whether a primary wired connection has been made. Once a wired connection has been made at 304, box 306 discovers backup wireless backup connection capabilities. A backup wireless display connection session is then set up at 308. At 310, the backup wireless display connection session is set to a paused mode. If it is determined that the primary wired connection is still active at 312, content is streamed using the primary wired connection at 314 (for example, from a transmitting device to a receiving device). Content is continued to be streamed at 314 until it is determined at 312 the primary wired connection is no longer active (for example, in some embodiments in response to an unplugging of the primary wired connection between a transmitting device and a receiving device). Once it is determined at 314 that the primary wired connection is no longer active, the backup wireless connection is un-paused at 316. If it is then determined at 318 that the primary wired connection has been restored, the backup wireless connection is again paused at 308 and flow continues. However, if it is determined at 318 that the primary wired connection has not been restored, and it is determined at 320 that the user has not manually disconnected the backup wireless connection, then content is streamed using the backup wireless connection at 322 (for example, from the transmitting device to the receiving device). Content is continued to be streamed at 322 until it is determined at 318 that the primary wired connection has been restored or it is determined at 320 that the user has manually disconnected the backup wireless connection.
It is noted that
In some embodiments of
In some embodiments, a policy can be set in a transmitting device to choose a wireless display method, connection, and/or protocol as a backup upon an occurrence where a wired connection is later unplugged (for example, for a later occurrence of a connected wired video out port is unplugged). The set policy can be overridden manually in some embodiments by user input via a user input provided on the device or in some embodiments by manufacturer configuration such as a manufacturer provided configuration file (for example, a Miracast connection is set as a backup for an HDMI connection, and/or a WiGig connection is set up as a backup for a DVI connection).
In some embodiments, when the transmitting device is connected to the receiving device via a wired interface, the transmitting device and the receiving device can exchange information on available backup interfaces that are active. For example, they may use one of the wireless interfaces to discover each other's capabilities corresponding to supported interfaces. It is noted that this interface need not be the same one that is actually used for connection. For example, a Bluetooth connection such as a Bluetooth Low Energy (BLE) stack can be used to discover whether the other device supports Miracast, WiGig, etc., while the actual backup connection is made, for example, over Wi-Fi Direct, Miracast, etc. In order to discover active physical interfaces, Extended Display Identification Data (EDID) information can be obtained through a currently connected wired link, for example.
In some embodiments, based on the transmitters backup connection policy and availability of a required wireless display transmission connection protocol on the receiver, the transmitter and/or the receiver can set up a wireless display session soon after the wired connection is made. The set up can be initiated in some embodiments from the transmitter, and the set up can be initiated in some embodiments from the receiver. The wireless display session can exchange media capabilities and setup the pipeline, without streaming any content (for example, audio video content) over the wireless connection while maintaining the wireless connection in a paused state.
In some embodiments, media streaming of content occurs on the wired interface until the wire is unplugged (for example, at either the transmitter or the receiver). An unplug event at either the transmitter or the receiver can result in a trigger to the paused backup connection, which may create an un-pause event for the wireless connection session. Media content on the transmitter can now be redirected from the wired interface to the wireless interface and streamed to the receiver via the backup wireless display interface. Since the backup wireless session can be pre-established, the transition can be quick and without any user visible glitch (and/or with a minimal user visible glitch).
The unplug event can be detected at the receiver end as well as the transmitter end. In this manner, both transmitter and receiver can detect the unplug event and switch to the earlier established backup connection.
Upon later restoration of the wired connection, the hot-plug event associated with the restoration can trigger a pause of the backup wireless display session, and media can be redirected to the wired interface. In this manner, streaming of media content can continue again from the transmitter to the receiver on the primary wired connection in a seamless manner. The backup wireless display session is then again set to a paused state so that it can again remain in the background and wait for another unplug event of the primary wired connection.
When the user is done using the primary wired interface and does not want the backup wireless interface to remain active in the background, the user can disconnect the backup wireless interface manually through a user interface provided for the backup wireless display (for example, in some embodiments, using user input device 202). The user can disconnect the backup wireless interface at any time—that is, the user can disconnect the backup wireless interface while the primary wired interface is in a connected or a disconnected state.
In some embodiments, display connection switching can be implemented in any device by an OEM for a better user experience. For example, in some embodiments, display connection switching can be implemented by an OEM in one or more of a computing device, mobile phone, smart phone, mobile device, handset, laptop computer, desktop computer, tablet computer, cable box, satellite box, set top box, television (TV), high definition television (HDTV), video and/or image streaming device, video and/or image transmitting device, Apple TV device, Chromecast device, Roku device, repeater, re-transmitter, streaming device, display hub, high definition (HD) display device, computer monitor, television (TV), high definition television (HDTV), and/or projector, among others. In some embodiments, display connection switching may be implemented in a processor and/or in a System on Chip (SoC) package (for example, with supporting software and/or to allow seamless switching between display connections such as wired and wireless connections).
In some embodiments, a user connects a smart phone via a wired USB Display connection protocol to an HDTV, and starts and app on the smart phone that can play movies on a second display screen (that is, on a screen that is not the display screen that is part of the smart phone). The movie starts on the display screen of the HDTV that is coupled to the smart phone via the wired USB Display connection protocol. While the movie is being transmitted from the smart phone and played on the HDTV, the user gets a phone call on the smart phone. The user decides to let others continue to watch the movie on the HDTV while the user takes the call on the smart phone in another room from where the HDTV is displaying the movie. The user disconnects the wired USB Display connection between the smart phone and the HDTV and moves to the other room to talk on the smart phone. After disconnection of the wired USB Display interface, the movie continues to be transmitted from the smart phone to the HDTV via a backup wireless connection according to some embodiments described herein. After the user is done with the call, the user plugs the smart phone back into the USB Display connection so that it can continue to charge via the USB Display connection with the HDTV. The other viewers of the movie on the HDTV continue to watch the movie the entire time with no (or little) perceived interruption during the unplugging, the phone call, and/or the re-plugging event.
