Patent Application
20170315769
The disclosure relates to the field of computing devices, and more particularly to the field of media computing devices.
Streaming multimedia devices such as ROKU™ or CHROMECAST™ are often used to play media to a television or other external display with minimal hardware and software features, as a dedicated media consumption device for home use. More advanced functions such as gaming or other software applications as may be commonplace in other computing devices, are not generally possible or when possible, they “take over” the television as the primary display and interrupt media consumption. Additionally, such devices generally operate directly via the television and any additional devices such as multiple-speaker arrangements for multi-channel audio are operate by the television or a separate media “head unit”.
What is needed, is a means to stream media to an external display device while allowing OS and application interaction via a remote, shared screen accessible via a user's mobile device, that can connect to multiple media destination devices for multicast streaming without the need for an external head unit.
Accordingly, the inventor has conceived and reduced to practice, in a preferred embodiment of the invention, a system and method for multiuser interaction with a media computing device with multiple virtual screens and personal area network capability. The following non-limiting summary of the invention is provided for clarity, and should be construed consistently with embodiments described in the detailed description below.
To address the problem of providing a means to stream media to an external display device while allowing wireless operating system (“OS”) and application interaction by one or more users of mobile electronic devices, the inventors conceived and reduced to practice a device that may be inserted into a standard high-definition media interface (“HDMI”) socket of a television, or into a similar media interface such as DisplayPort or other media adapter port in a television or similar media device. The media computing device has a complete operating system such as ANDROID™, IOS™, LINUX™, or WINDOWS™. It is equipped with one or more wireless network interface circuits, enabling it to communicate via WiFi with other devices. The device is controlled by users of remote mobile devices such as smart phones or tablets, via WiFi. The media computing device does not necessarily have any built-in user interface, but rather uses a virtual screen driver to provide full operating system user interface screens to users of mobile devices. One or more virtual screens may be operated simultaneously by mobile device users. A mobile device user is presented with a typical operating system home screen or desktop (depending on the operating system), and can interact with the screen using touchscreen capabilities to perform any actions normally available in the operating system. The home screen, virtual screen, or virtual desktop appears within an application on the mobile device, thus providing a “full OS inside an app” modality to the user, with actions taken by the user affecting what appears on a television.
The delivery of virtual screens to mobile devices from the media computing device may be done by intercepting screen graphics bitmaps (which would normally be sent to a hardware display device for rendering), and transcoding the graphics data into H.264 (for example). The H.264 stream can then be sent in packetized form over a wireless network to each of the mobile devices. Similarly, user interaction events received on the mobile devices (for example, touchscreen interactions) are sent in packetized form over the wireless network to the media computing device, where they are provided to and interpreted by the operating system as if they were user interaction events arriving from an attached touchscreen. In some use modes, each user sees the same OS screen on his mobile device. In one of these modes, each user can simultaneously interact with the OS via his mobile device and the OS uses an interrupt management system (common in operating systems) to ensure that each user's interactions are handled in a timely manner. In another use mode involving a shared virtual screen, only one user at a time has control of the user interface; users could take turns controlling, or users could “seize control” with or without the concurrence of other users (quasi-competitive control of the shared user interface could be part of a game concept). In another use mode, each user is provided with his own virtual screen. For example, many operating systems provide for multiple virtual desktops, so that a user may use different applications on different desktops. In the use mode envisioned, each user interacts with the operating system using his own logical/virtual desktop, which is provided wirelessly as before.
Using multiple virtual screens streamed to mobile devices enables a variety of use cases for users, including new ways to enjoy video games, watch video content, or listen to audio both actively and passively in the background. Multiple users wishing to play a video game may use their smartphones, tablets, or other mobile devices as both display screens and controllers for new multiplayer game types, such as multiple users cooperating to control the bridge of a ship in a simulation game. Each player sees their respective game environment on their mobile device screen, such as their particular control station or immediate surroundings (for example, using hardware sensors in the mobile device to enable a user to “look around” by moving their device). On the television or similar media device, an overview of the game is shown, such as a map or a view of the ship's entire bridge, showing all players and the game environment in a single view. As players interact with their devices to react to game events, interact with each other through the game, and take in-game actions, the various game views being shown are updated in response to these interactions to reflect the ongoing game state. If a player moves about the room, their mobile device continues to act as their localized input and output device for the game, allowing them to continue playing, for example, even when they leave the room temporarily such as to use the restroom, prepare food, answer the door or phone, etc.
Using streamed virtual screens for presenting information and receiving interaction, it becomes possible to enable individual media consumption for each user by providing their specific media content to their device and receiving their interactions such as media selection or control interactions, without affecting other users or the media being shown on a connected television or other media device. Additional connected devices such as networked speakers in a multi-room audio arrangement may be utilized in conjunction with streamed virtual screens to accommodate more complex use cases, such as position-based multi-room audio. As a user moves about within a multi-room audio setup, their mobile device's position tracking (such as using network signal or GPS sensors) may be provided to the media computing device, which then directs the connected audio devices accordingly so that the user is always listening to their specific audio selection via the nearest speaker or other device (for example, using integrated speakers on a connected television or computer monitor when available). When multiple users move about, media streaming is continuously updated so that each user's personalized media selections are sent to the appropriate audio device, and conflicts may be resolved using preconfigured handling rules such as “first come, first served” or a user hierarchy such as giving priority to the user that owns the media computing device or is hosting the gathering.
Using personal area network functionality, a user may view and interact with their connected internet-of-things devices using a media computing device as a hardware “hub”, removing the need for multiple hubs or bridges to connect devices from different manufacturers or that use different protocols. This also enables a convenient, unified interface for interacting with these devices while the user is already connected to the media computing device, removing the need for multiple software applications or additional configuration, and it also enables integration of these devices with other functions of the media computing device, such as to cause device operations to occur based on media playback or complex rules configured within the media computing device that may not be possible within an IoT device or hub normally.
By offering a wide-area network interface for use, a media computing device can serve as a backup Internet connection when a local network is unavailable, enabling full functionality regardless of network setup or state. This allows a user to utilize the full functionality of the media computing device while traveling or during periods of connectivity loss on their local network, and enables the use of the media computing device as a WAN access point or a fallback modem for a home network, removing the need for separate devices to perform those roles.
According to a preferred embodiment of the invention, a system for multiuser interaction with a media computing device with multiple virtual screens is disclosed, the system comprising: a media computing device comprising a processor, a memory, a high-definition multimedia interface adapter, a wireless network interface, a virtual screen driver, and an operating system; and a plurality of mobile devices, each comprising at least a processor, a memory, a touchscreen display, and a wireless network interface. According to the embodiment, the media computing device sends screen graphics via the virtual screen driver to the plurality of mobile devices using the wireless network; each of the plurality of mobile devices displays a virtual screen of the operating system using the screen graphics sent by the media computing device; and touchscreen user interaction events are transmitted from the plurality of mobile devices to the media computing device and processed by the operating system thereof.

According to a further preferred embodiment of the invention, a method for handling multi-user audio using multiuser interaction with a media computing device, comprising the steps of: transmitting screen graphics generated by a virtual screen driver of the media computing device, the screen graphics corresponding to a virtual screen comprising a media control interface, to a plurality of connected mobile devices; receiving, at the media computing device, a plurality of user interaction events from the plurality of mobile devices; selecting a plurality of audio playback devices based on a first user interaction event; selecting media content for playback based on a second user interaction event; and wirelessly transmitting, from the media computing device, audio from the selected media content for playback at the plurality of audio playback devices. According to further embodiments of the invention, the method further comprises the step of sending, using a high-definition multimedia interface adapter of a media computing device, high-definition video and a plurality of audio channels associated with the media content to a high-definition multimedia display device physically connected to the high-definition multimedia interface adapter of the media computing device. In yet another embodiment, playback of the video and audio sent to the high-definition multimedia display device is synchronized with playback of the audio transmitted to the plurality of audio playback devices.

It should be noted that, while HDMI is used in the example of
According to various alternative arrangements, virtual screen driver 118 may connect via physical connections such as a USB cable (or other cable connections), for example to connect to a mobile device 120a-n with particular hardware capabilities, such as a personal computing device that may have a USB port but no active network connection. Wireless network interface 102a-n may use a variety of different technologies or protocols, such as using various frequency bands or channels for WiFi connectivity, BLUETOOTH™, cellular radios, or other network connection types, to connect mobile devices 120a-n to media computing device 110.
Virtual screen driver 118 may operate multiple connections for multiple mobile devices 120a-n, for example so that more than one user may interact with the operating system of media computing device 110. According to various arrangements, each mobile device 120a-n may be presented a separate “instance”, or copy, of an operating system home screen or other virtual screen, so that each user may have access to the operating system for interaction without being affected by the activities of other users that may be connected. In some arrangements, user access may be restricted such as to provide read-only access to some portions of an operating system, or to restrict software applications or functions based on configured criteria such as mobile device or connection type, or using stored software-based whitelisting or blacklisting behavior. In other arrangements, multiple mobile devices 120a-n may be presented with the same instance of a home screen, so that multiple users may interact collaboratively such as to work together while editing stored files, or to interact with a shared screen in a gaming application, or other shared-use cases. When multiple users are connected to a single virtual screen driver 118, congestion may be managed by operating a “safe mode” or minimal interface for new users, such as when system resources are limited or after a set number of concurrent users has been reached (for example, providing a full interface to the first four users and a stripped-down interface to any users after that). For example, a new user connecting may be presented with a notification that the maximum number of connections has been reached, or that resources are limited, and be prompted to abort or continue with limited functionality. A limited interface may comprise, for example, basic remote control functionality to direct the operation of media management subsystem 117 remotely, for example features such as “next track”, “play/pause”, or volume controls. In this manner, additional users may still be able to control media being viewed on display device 130, without requiring full OS interaction.
Operating system 116 may operate a variety of software applications, for example from an app store such as GOOGLE PLAY™ or similar, according to the nature of a particular operating system (for example, apps from GOOGLE PLAY™ may be natively supported on any ANDROID™ operating system, or apps from the Apple App Store on an IOS™ operating system). In this manner users may utilize familiar software and compatibility may be “future-proofed” by utilizing existing repositories and standards to ensure forward-compatibility with new software developments. While running software applications, multiple users may connect and interact via their mobile devices 120a-n, for example for multiple users to play a multiplayer video game application. According to various arrangements, multiple users may share a single screen during interaction, each viewing and interacting with the same instance of the operating system interface, or users may each view and interact with a separate instance, or various combinations thereof. Using multiple screen instances in this manner may be used to provide complex interaction environments for multiple users, for example for a video game application wherein a display device 130 may present an overview of a game environment (such as a game board, map, aircraft cockpit, ship bridge, or other group or overview type environment according to the particular application or use case), while each mobile device 120a-n may present a user-specific view such as that particular player's game information (for example, character or player statistics) or their particular game environment (for example, their specific character's view of a game world, or a small-scale map centered on their location within a larger overview map shown on display device 130, or their specific controls or station in a cockpit or bridge environment).
According to an exemplary arrangement, audio may be multicast with minimal latency for synchronized playback at multiple audio devices 201a-n, for example by using a wireless interface 102a-n to function as a wireless access point (WAP) in an infrastructure mode, wherein audio devices 201a-n may connect directly to the WAP rather than connecting to a home router or other access point (thereby reducing the number of “hops” or network nodes the audio must traverse between source and destination).
According to another exemplary arrangement, audio may be streamed to multiple audio devices 201a-n wirelessly, and selection of audio devices 201a-n for streaming may be updated according to various factors such as network performance, media attributes (such as streaming to a subwoofer device for bass-heavy audio tracks, but stopping the stream to that device if the audio style changes) or mobile device location. For example, a user may have multiple audio devices 201a-n placed in different areas or rooms. As the user moves about, media may be streamed to the nearest audio device(s) based on location or network information from their mobile device (such as using WiFi or BLUETOOTH™ signal strength or triangulation). In such a use mode, each connected user may select their own media, optionally from a streaming third-party source such as that user's SOUNDCLOUD™ or PANDORA™ account, and the user-specific media selection will “follow” the user by their location so that each user only hears their own media. When multiple users enter the same area, they may optionally be prompted for new media selections, for example incorporating each user's preferences or media collection so that a group may select music that appeals to everyone or setup a playlist using media from each user's respective library so that everyone gets a chance to hear their selection. Additionally, while audio is being streamed to multiple devices in this manner, video (optionally with its own audio) may be shown on a connected HDMI display device 130a-n, for example a music video corresponding to the nearest user's music selection, or a separate media selection entirely. This content may optionally be based on selection from users in the vicinity of the display device 130a-n, in a manner similar to each user selecting media to hear from their nearest audio devices.
According to the embodiment, wireless interfaces 102a-n may comprise a variety of wireless networking or direct-communication protocols or technologies, for example including a local area network (LAN) interface 102a, BLUETOOTH™ interface 102b, wide-area network (WAN) interface 102c such as an LTE modem for connection to a wide-area network 901 such as a cellular network (for example, to enable Internet access and media streaming during travel use, such as plugged into an automobile entertainment console, or for use as a cellular modem or hotspot, or to enable interaction with connected IoT devices 140a-n from outside the local network), and personal area network (PAN) interface 102n configured for connecting to a plurality of network-capable internet-of-thing (IoT) devices 920a-n across short distances using low-power communications, such as ZigBee, Z-WAVE™, or INSTEON™ (for example). PAN interface 102n may be directed by a PAN controller 910, for example a ZigBee Coordinator that may form the root of a ZigBee network of IoT devices 920a-n. In a ZigBee network, multiple devices 920a-n may be controlled by a single ZigBee Coordinator, which functions as the root node for the network structure. Each of a plurality of additional devices 920a-n may operate as a ZigBee Router or a ZigBee End Device, according to their function or position in the network structure. A ZigBee Router may act as an intermediate router between the Coordinator and a plurality of additional End Devices, relaying communication to extend the network (ZigBee direct communication is generally limited to 10 to 20 meters) or to provide logical organization to devices in the network (such as having a router for a particular type of device, or a particular physical area). In this manner, PAN controller 910 may operate as an IoT hub, removing the need for a separate device to manage IoT devices and protocols and providing native connectivity to a variety of protocols and technologies while managing their functions and operation.
PAN communication methods may be used to enable connections to a plurality of IoT devices 920a-n, such as including (but not limited to) smart home hubs, light bulbs or switches, power outlets, or connected appliances. According to the nature of specific devices or communication methods, devices may connect to one another to form a mesh network and overcome communication limitations (for example, ZigBee generally has an operating range of 10 to 20 meters, which may not cover all connected devices in a building or other environment) or to use a central hub device such as home automation hubs produced by SMARTTHINGS™ or similar, to connect multiple devices with varying capabilities and expose their respective functionalities via a single unified connection. In this manner, a media computing device 110 may connect to a hub or other device 920a and communicate via that device to additional connected devices 920n, enabling connectivity and operation across a wide range and variety of communication protocols. Additionally, by utilizing a WAN interface 102b, some arrangements may provide interaction with connected IoT devices 920a-n from outside the local network, for example so that a user may configure or manually direct devices while they are away from their home or office. For example, a user may be able to adjust their connected thermostat or air conditioning device so that when they return home their house will already be at their preferred temperature, or they may activate a connected camera to check on their home's security, or they may receive notifications from devices such as security devices or environment sensors. This further removes the need for extraneous devices by enabling a media computing device 110 to function not only as an IoT hub but also as a cellular modem, acting as a bridge between the user's local network and the Internet for remote access and additional functionality. For example, another function that may be provided via a WAN 901 may be streaming media from external sources such as YOUTUBE™ or other media providers, enabling a user to connect to the Internet and utilize these services while traveling or when no local network may be available. This may also be used as a redundancy failsafe, for example if a local connection is experiencing difficulties such as network congestion or a hardware failure. In such a situation, a WAN interface 102b may connect directly to WAN 901 so that operation may continue uninterrupted until the LAN 102a connectivity is restored.
By connecting via wireless interfaces 102a-n to IoT devices 920a-n, a media computing device 110 may interact with and direct the operation of such devices either automatically or based on received user input (such as from a mobile device 120a-n). For example, during video playback a plurality of IoT lights 920a-n (such as network-connected LED bulbs or light switches controlling non-connected traditional light bulbs) may be directed to alter their intensity or color based on the video frames being shown, to enhance the viewing experience or to reduce eyestrain. In another example, a user interacting with media computing device 110 via their mobile device 120a-n may manually control the operation of available IoT devices 920a-n via the media computing device 110, without the need for an external software application or control interface. In this manner, media computing device 110 may function as an IoT hub device, connecting a variety of IoT devices 920a-n and directing their operation or presenting their functions and information in a unified manner.
In an instantiated-screen usage mode, each connected user may view a distinct instance or copy of an OS screen, such as an application screen, home screen, or desktop. Each user may view and interact with OS features such as applications or files, without being affected by other connected users (and may not even know how many other users are connected, if any). Such an operation mode may be useful, for example, for enabling users to work on files or documents separately using the shared computing resources of the media computing device, while simultaneously viewing media on a connected display device.
If a resource is locked, the virtual screen driver 118 may then check for a configured operation mode for resolving interaction conflicts 405. If the operating mode is configured to resolve interaction conflicts using interrupt-based handling, an interrupt request may be generated 407, unlocking the element and interrupting or cancelling any operation that the locking user was performing, such as to “drop” a window the user was in the middle of “dragging and dropping” as part of a user interface interaction, or removing control of a shared keyboard or other interaction device and then completing the interaction received from the interrupting user 409. When a user is interrupted, a notification may optionally be presented on their mobile device so they are aware of the event. Interrupts may be processed fluidly enough that the users may not even be aware they are happening, for example if a user is interrupted while dragging an interface window, they may only see that another user has clicked and is now dragging the window in another direction, and they may then click and drag again if they wish, all occurring fluidly as it would normally in a single-user environment.
If the conflict resolution mode is instead configured not to use interrupts and to maintain a “single-seat control” operation scheme, the user currently interacting with and locking an element maintains control (optionally being notified of the attempted interaction), and the new interaction is cancelled or ignored 406. In a single-seat operation mode, only a single user may control a particular element or resource at a time, and new interactions may not be processed for an element or resource until a current interaction is completed (thus relinquishing control). This may be thought of as a user “driving” an interaction or element, and other users being “passengers” until they are finished. Once control is relinquished, other users may then “take over” and interact with the now-unlocked element or resource.
In a single-screen usage mode, each connected user interacts with the same instance or copy of an operating system, potentially interacting with or affecting other connected users. While interacting with the same instance of the operating system, users may be able to view the same screen simultaneously, such as to view the same file or document for collaborative work, or they may view different information on their respective mobile devices such as (for example) separate applications or files. An exemplary use for this operation mode may be a multiplayer video game, where each user is presented with their own personal view of the game, and an overview or admin view is presented on a connected display device. For example, in a first-person shooter type game, each player may be shown their own character's information such as health or ammunition, or a local map based on their character's immediate vicinity. On a connected display device, an overview map of the entire playing field may be shown, or global game information such as a score list for all players. Another exemplary use may be a ship (or spaceship) simulation, wherein the connected display device shows an overview of a ship's bridge, reflecting current in-game conditions such as (for example) player characters at their stations, weather or lighting effects, other vehicles or characters outside the bridge visible through windows or screens, or other such game events. Each player may then be shown their specific station or controls on their mobile device, so that each player may assume the role of a crew member on the bridge, operating their specific set of controls and systems without seeing or being able to interact with another player's controls or systems. As players interact with their specific screen instance, the effects may be shown on the overview page (such as a player toggling the bridge lighting, for example), and optionally on other players' screen instances where appropriate.
In this manner, all affected views and displays are updated when actions take place, for example to show players the effects of interacting with each other while masking those interactions from uninvolved players, or to show the effects of player actions in an overview display. In a ship bridge simulation example, as players take action on their respective control consoles within the bridge, the results may be reflected in the overview display such as altering lighting or other simulated systems operating on the ship's bridge, or showing the environment changing outside the bridge as seen through windows or displays such as to show the effects of navigating the ship or engaging in combat. In a roleplaying game, a map may be updated as individual players explore, and interactions between players or between a player and a non-player character may be shown to the involved players only, simulating the effects of participating in private conversations within the game environment and encouraging players to cooperate with each other in new ways to share, conceal, or manipulate information obtained.
If the interaction includes a change in audio device selection 605a, media may be presented to the newly-selected device 604 and playback halted or quieted at the previous device. Device selection may occur due to the user specifically selecting a new device via manual interaction, or it may be partially or fully automated based on information from hardware sensors or a network interface on the mobile device, which may be provided as an interaction without manual operation by the user. For example, as the user moves about their location information may be updated and sent as a new interaction to automatically select a new audio device that is closer to the user's new position than the previously-selected device, or that has preferable network signal quality. In this manner, the user may move about freely while still listening to their media, as playback “follows” them by updating the devices in use. By muting or stopping playback at previous devices and playing only through the current “ideal” device, multiple users may move about and listen to their own media each through their respective audio device. Alternately, by varying the playback volume instead of completely halting playback at previous devices, audio may smoothly transition as the user moves about, being loudest at their location and quieter on devices further away. To an observer, this may be perceived as though the media is originating at the user's location and the volume trails off as distance increases, facilitating an immersive form of virtual surround or position-based audio.
Additionally, a user may be able to configure automated operation of PAN devices such as by configuring rules 1413a-n, for example to direct appliance to perform actions at specified times or lights to turn on or whenever another action is detected on the network (for example, if a motion or door sensor detects the user has entered a room or building), or to configure devices to operate in response to conditions or action on media computing device 110, such as to configure lights to operate in response to media being viewed. In this manner, using media computing device 110 as a PAN hub adds new functionality by combining the various functions of a user's IoT devices directly with their media collection and other functions of media computing device 110, without the need for additional hardware or complicated technical setup. Additionally, this enabled the configuration of complex rules and operation logic that may not otherwise be possible by configuring PAN devices directly or by using existing hub devices, by utilizing the more powerful storage and computing hardware of media computing device 110.
However, if no LAN is found (or if a LAN is found but has no external connectivity), a media computing device 110 may then scan for an available WAN 1605 such as a cellular network that may be used. If a WAN is available, the device may connect 1606 and begin broadcasting as a network access point 1607 and listening for user connections 1608 for operation. In this manner, a user may connect to a media computing device 110 and utilize its functions without the need for a configured LAN, such as when traveling or during periods of network loss. This enables the use of a media computing device 110 as an access point to allow WAN connectivity for user devices that may not have that functionality, such as a laptop personal computer, as well as allowing full network functionality such as streaming media and Internet browsing when no LAN is available. This also enables the use of media computing device 110 as a fallback network connection for a LAN, to continue operation uninterrupted during network outages or hardware resets or failures. These operation modes remove the need for separate and often expensive devices to perform these roles, offering a user an “all-in-one” device for network, media, and IoT functionality.
If no WAN is available, a notification may be produced for presentation to a user (either upon connecting with their mobile device, so that upon connecting they are immediately notified, or via an integral notification mechanism such as an LED or hardware speaker) to alert them of limited connectivity, and may optionally offer limited functionality 1610 such as for interacting with operating system features or viewing locally-stored media, or other operation that may not require a network connection.
Generally, the techniques disclosed herein may be implemented on hardware or a combination of software and hardware. For example, they may be implemented in an operating system kernel, in a separate user process, in a library package bound into network applications, on a specially constructed machine, on an application-specific integrated circuit (ASIC), or on a network interface card.

In one embodiment, computing device 10 includes one or more central processing units (CPU) 12, one or more interfaces 15, and one or more busses 14 (such as a peripheral component interconnect (PCI) bus). When acting under the control of appropriate software or firmware, CPU 12 may be responsible for implementing specific functions associated with the functions of a specifically configured computing device or machine. For example, in at least one embodiment, a computing device 10 may be configured or designed to function as a server system utilizing CPU 12, local memory 11 and/or remote memory 16, and interface(s) 15. In at least one embodiment, CPU 12 may be caused to perform one or more of the different types of functions and/or operations under the control of software modules or components, which for example, may include an operating system and any appropriate applications software, drivers, and the like.
CPU 12 may include one or more processors 13 such as, for example, a processor from one of the Intel, ARM, Qualcomm, and AMD families of microprocessors. In some embodiments, processors 13 may include specially designed hardware such as application-specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), field-programmable gate arrays (FPGAs), and so forth, for controlling operations of computing device 10. In a specific embodiment, a local memory 11 (such as non-volatile random access memory (RAM) and/or read-only memory (ROM), including for example one or more levels of cached memory) may also form part of CPU 12. However, there are many different ways in which memory may be coupled to system 10. Memory 11 may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like. It should be further appreciated that CPU 12 may be one of a variety of system-on-a-chip (SOC) type hardware that may include additional hardware such as memory or graphics processing chips, such as a QUALCOMM SNAPDRAGON™ or SAMSUNG EXYNOS™ CPU as are becoming increasingly common in the art, such as for use in mobile devices or integrated devices.
As used herein, the term “processor” is not limited merely to those integrated circuits referred to in the art as a processor, a mobile processor, or a microprocessor, but broadly refers to a microcontroller, a microcomputer, a programmable logic controller, an application-specific integrated circuit, and any other programmable circuit.
In one embodiment, interfaces 15 are provided as network interface cards (NICs). Generally, NICs control the sending and receiving of data packets over a computer network; other types of interfaces 15 may for example support other peripherals used with computing device 10. Among the interfaces that may be provided are Ethernet interfaces, frame relay interfaces, cable interfaces, DSL interfaces, token ring interfaces, graphics interfaces, and the like. In addition, various types of interfaces may be provided such as, for example, universal serial bus (USB), Serial, Ethernet, FIREWIRE™, THUNDERBOLT™, PCI, parallel, radio frequency (RF), BLUETOOTH™, near-field communications (e.g., using near-field magnetics), 802.11 (WiFi), frame relay, TCP/IP, ISDN, fast Ethernet interfaces, Gigabit Ethernet interfaces, Serial ATA (SATA) or external SATA (ESATA) interfaces, high-definition multimedia interface (HDMI), digital visual interface (DVI), analog or digital audio interfaces, asynchronous transfer mode (ATM) interfaces, high-speed serial interface (HSSI) interfaces, Point of Sale (POS) interfaces, fiber data distributed interfaces (FDDIs), and the like. Generally, such interfaces 15 may include physical ports appropriate for communication with appropriate media. In some cases, they may also include an independent processor (such as a dedicated audio or video processor, as is common in the art for high-fidelity A/V hardware interfaces) and, in some instances, volatile and/or non-volatile memory (e.g., RAM).
Although the system shown in
Regardless of network device configuration, the system of the present invention may employ one or more memories or memory modules (such as, for example, remote memory block 16 and local memory 11) configured to store data, program instructions for the general-purpose network operations, or other information relating to the functionality of the embodiments described herein (or any combinations of the above). Program instructions may control execution of or comprise an operating system and/or one or more applications, for example. Memory 16 or memories 11, 16 may also be configured to store data structures, configuration data, encryption data, historical system operations information, or any other specific or generic non-program information described herein.
Because such information and program instructions may be employed to implement one or more systems or methods described herein, at least some network device embodiments may include nontransitory machine-readable storage media, which, for example, may be configured or designed to store program instructions, state information, and the like for performing various operations described herein. Examples of such nontransitory machine-readable storage media include, but are not limited to, magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as optical disks, and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM), flash memory (as is common in mobile devices and integrated systems), solid state drives (SSD) and “hybrid SSD” storage drives that may combine physical components of solid state and hard disk drives in a single hardware device (as are becoming increasingly common in the art with regard to personal computers), memristor memory, random access memory (RAM), and the like. It should be appreciated that such storage means may be integral and non-removable (such as RAM hardware modules that may be soldered onto a motherboard or otherwise integrated into an electronic device), or they may be removable such as swappable flash memory modules (such as “thumb drives” or other removable media designed for rapidly exchanging physical storage devices), “hot-swappable” hard disk drives or solid state drives, removable optical storage discs, or other such removable media, and that such integral and removable storage media may be utilized interchangeably. Examples of program instructions include both object code, such as may be produced by a compiler, machine code, such as may be produced by an assembler or a linker, byte code, such as may be generated by for example a JAVA™ compiler and may be executed using a Java virtual machine or equivalent, or files containing higher level code that may be executed by the computer using an interpreter (for example, scripts written in Python, Perl, Ruby, Groovy, or any other scripting language).
