FIELD OF THE INVENTION
This invention relates generally to a content delivery system and method for enabling a user's freedom of mobility while maintaining access to “real-time” on-going content without substantial interruption to the content delivery and without requiring user intervention; even as the user transitions from one physical location where the content is accessed from multimedia data processing system (referred to as target device herein) on one network environment to the next physical location with different target device on a different network environment. More particularly, the present invention improves content delivery between a smart personal device and a plurality of target devices while reducing power consumption of the devices; and being able to pull desirable content from the target devices including but not limited to contents located on a single network location, on multiple network locations, and content hosts located over the internet.
DESCRIPTION OF THE BACKGROUND ART
Technology has brought us the personal computer (PC), HDTV, Digital personal Multimedia player, Personal Video Recorder, Smart Phone . . . however in our daily interaction with these analog and digital target devices we are still limited under the current model of being tied down to the physical location of each of these devices, i.e. the content is always accessed by user within proximate to the given device whereas the contents are either stored, displayed, or being sourced from the device. The physical distance limitation restricts a user to sit in front of a PC, sitting around a TV and PVR to watch a TV content, which severely limits our freedom of mobility especially when a user may have multiple TVs and multiple work environments in one location. The content is delivered to each physical device by plurality of ways is another limitation in that a HDTV devices can receive contents from Cable, antenna, satellite dish, USB, Ethernet LAN, Wireless LAN. Even when devices receive content via a similar source, each device would need to be interface and programmed individually. Another limitation is that contents are only accessible on each physical target device with its own unique user interface or being able to remote controlled. User has to learn the user interface and or control buttons of each device to operate from simple turning on and off to gaining access to the content of a selected device. Another drawback from the current content accessing model is wasted energy and bandwidth requirements. With multiple target devices around a home or office, we have to turn on a device when we desire to operate or access the contents upon entering its surrounding location. Frequently we have these devices turned on in multiple locations so a user can be mobile from one location to another, using transmission bandwidth for each unit even though a user is no longer proximate to the device. Another drawback from the current content accessing model is that the content to be access by the user are store either within these target devices or close by the physical device itself i.e. a home entertainment center including a TV, a DVR, a music system . . . etc. As a result, plurality of remote control devices might be implemented to provide users with access to content and operations with all devices located proximate of each other. We are well aware of the inconvenience of plurality of remote devices around a given location. The inefficiency in the current model produces undesirable side effects such as in the case of leaving the devices turned on, which include wasted electricity, running up the usage of the devices thus reducing the useful life and dealing with the heat generated by the devices. In addition, managing multiple user interfaces and remote controls for each of the devices is time-consuming and can be frustrating. Another undesirable side effect is the potential of interference of these devices on wireless networks amongst each other. One of the disadvantages from the user's perspective is the inherent deficiency in the physical range limitation of device centered sourcing and control, which prohibits the continuity of operations and content access and delivery when user physically moves from one location to another.
Accordingly, the prior art systems for delivering and accessing content from these target devices have significant disadvantages and limitations. It would, therefore, be highly desirable to employ a smart apparatus which can eliminate the problems of the conventional process and allows users to have freedom of mobility while accessing the desired contents spanning multiple target devices without interruption and without requiring user intervention.
SUMMARY OF THE INVENTION
A smart personal device is a digital Device which can discover, register, activate, deliver content and deactivate of a plurality of target devices including but not limited to HDTV, PVR, PMP, PC, DVR around a home, office, hotel room, conference center as described herein. The smart personal device can be embedded within a digital device including, but not limited to, a smart phone, a personal computer, a laptop, a netbook, a GPS, a personal multimedia player, video MP3 player, a portable radio or a tablet PC.
The smart personal device is used to first discover multiple target devices upon identifying one or more target device(s) located proximate to the smart personal device. The present invention uses RFID solution for discovering target devices around one or more physical locations, although it is not limited to a specific communication technology in the future (i.e. wireless USB, wi-fi, RF, FM, Cable, etc). Once a target device is discovered and registration steps are completed, the target device in one embodiment to be placed in a sleep mode if the target device is not being used by a user or there is no smart personal device is in proximate to the target device. Upon the smart personal device identifying one or more target device located proximate to the smart personal device and based on the desired state of the smart personal device, it will automatically wakeup and activate one or more of the target devices and deliver content to the target device to meet the need of the user. These include but not limited to receive and display contents from the Personal Smart Device as in the case of a HDTV, receive and play contents from the smart personal device in the case of a digital speaker system, receive and display contents of an application as in the case of a personal computer. When the smart personal device is no longer proximate to the target device, the target device will be deactivated by the Personal Smart Device and resume its sleep mode.
The present invention is a system and method which overcomes the limitations and disadvantages of the prior art by providing a simple and convenient way of allowing a user with freedom of mobility and to move from one environment to another while continually accessing his content without interruption.

DETAILED DESCRIPTIONS OF PREFERRED EMBODIMENTS
Before describing the preferred embodiment in detail, a description of some of the terms used herein may assist the reader to understand the present invention.
DISCOVERY: The smart personal device enables a user to select a discovery mode from which the smart personal device will discover target devices which are capable of being interacted by the smart personal device. The discovery method currently contemplated comprises, but is not limited to, using any one or more of the following: RFID, wireless, powerline, FM, LAN, USB networking communication media. The preferred embodiment of the present invention is described in the context of discovering a RFID device which is built within or associated with each target device while a smart personal device is located proximate to the target device. During the discovery process, the smart personal device initiates all its tasks and performs all functions while target device can be passive and its main electronics other than the minimal components may be powered off or in low power sleep mode other than the minimal functions including but not limited to the RFID and Wake on LAN or Wake on USB. Once the smart personal device identifies a suitable target device located proximate to the smart personal device, it will register the target device and its functional characteristics such as TV, HDTV, DVR, Music systems in the smart personal device's configuration table. The smart personal device at its option, depending on its programming and user and/or system preferences and requirements may perform a quick test to confirm the target device's capability even if the target device is in active operation without disrupting any user action to confirm the target device's capability. During the quick test, If the target device is powered off or in a low power sleep state, the smart personal device can wake up the target device by using an industry standard method including but not limited to wake on LAN or wake on USB method. The smart personal device is capable to perform rediscovery update operation either upon user's selection or perform at a fix interval to detect if there is any new target device since the last discovery operation. If a new target device is discovered the smart personal device will alert the user and enable the user to choose to ignore or to add the newly discovered target device to the configuration table. A target device may include a configuration option for not be discovered or only be discovered and registered by if the smart personal device meets certain parameters including but not limited to authorize by user, by device type, by password, by functionality. REGISTRATION or REGISTERING: Upon a successful discovery of a target device, the smart personal device is capable of registering relevant characteristic of the target device by storing in the configuration table of the smart personal device. The relevant characteristic of the target device may include but not be limited to brand, model, maker, MAC ID, CPU speed, main memory size, disk storage size and type, network capability, smart Direct I/O capability, GPS location, input I/O type, output I/O type. Once registered, the target device is available to be woken from a low power sleep state and ready to perform operation upon command including but not limited to receive and display content or to transfer content to the smart personal device. The present invention uses the smart personal device to perform all the necessary discovery and registration tasks independent of the target device while the target device is passive or in a low power sleep mode. In an alternative embodiment, the discovery and registration steps can be easily performed with active participation by the smart personal device and target device. In one embodiment of a related invention the target device performs the role of Discovery and Registration whereby the target device identifies a smart personal device located proximate to the target device and performs all operations to discover and register the smart personal device while the smart personal device is passive till the target device activates the smart personal device. ACTIVATION: Once the smart personal device identifies a target device located proximate to the smart personal device and confirms in the configuration table that it is a valid and registered target device, it will automatically perform a wakeup commands to the target device without the awareness of the user. In addition, if the smart personal device is being used by the user to perform an ongoing live operation including but not limited to a Windows or MAC or Google application such as word processing, windows office, playing music, video playback, TV broadcasting program, internet related operations such as search, news, blogs, purchase, etc., the smart personal device will command the target device to instantaneous switch from the low power sleep state to an active state to perform I/O operations on the target device. The present invention will enable the target device, if it's already performing an operation, to automatically perform a split screen if the target device includes a display unit and has the split screen capability. One or more target devices may be activated at the same time within proximate to the smart personal device, i.e. PC and printer, HDTV and DVR. DELIVERY CONTENTS: Contents are delivered from the smart personal device to one or more target devices via various means including but not limed to wireless Ethernet 802.11 G/B/N/A, USB wireless, mobile phone wireless, powerline, RF, FM etc. In one embodiment of the present invention, the content is delivered from the smart personal device to the target device using one of the target device's input unit controllers. If the target device is a HDTV, the input unit controller is capable of receiving content from input source including but not limited to antenna, cable, wireless LAN, RF, FM, LAN, wireless USB. If HDTV comprises a HDTV Core Media Processor than its CPU, main memory, output unit controller will be activated to receive the content from the smart personal device using its input unit controller, transmit the content to the CPU/main memory using the I/O BUS. After the CPU process the content, it will transfer the content to the output unit controller using the I/O BUS and the output unit controller will display the content on the target device. In this embodiment, the majority of the digital logic will be powered to perform the function. In another embodiment, whereas the target device comprising smart input I/O controller and smart output I/O controller, once the target device is being activated by the smart personal device and properly configured by the Direct IO manager of the target device, the smart input I/O unit controller is capable of receiving the content from the smart personal device and deliver the content directly to the output I/O unit controller using the I/O BUS independent of the Core Media Processor and Main Memory. In addition, in this embodiment of Direct I/O method, the Core Media Processor and Main Memory can be turned off or to be in a low power sleep mode thus significantly reducing power required for the operation. This Direct I/O method may be enabled in devices including but not limited to HDTV, Music systems, Personal Computers or target device comprising at least one smart Input unit controller, one smart storage unit controller and one smart output unit controller. In another embodiment, when the smart personal device is leaving one target device and arriving at a different target device, the smart personal device upon detection of it is no longer proximate to the first target device it will automatically store the content in a temporary buffer or storage unit and suspend the content delivery to the target device by marking or bookmarking the current position using the intelligence on the smart personal device unit. Upon identifying a new target device or back to the original target device located proximate to the smart personal device, it will first deliver the content from its temporary buffer or storage unit therefore there is no interruption or loss of the content while the user is transitioning from one target device location to the next by resuming the content delivery from the previously marked or bookmarked position. The present invention describes content delivery from the smart personal device to a first HDTV target device and redirect the content to a second HDTV target device whereby the target device located proximate to the smart personal device. In another embodiment of the present invention the smart personal device is receiving a live digital FM broadcasting contents while delivering the FM broadcasting contents to a digital speaker system (Target device #1) in a home location on network #1. When the user is leaving the above described home location and entering in a second location i.e. an automobile with a digital speaker system, the smart personal device will first deactivate the first target device on network #1 when the first target device is no longer proximate to the smart personal Device (the first time), automatically start storing or recording the content from the FM broadcasting on its storage unit. Upon identifying the digital speaker system (Target device #2) in the automobile on network #2 located proximate to the smart personal device (the second time), it will activate the target device #2 and resume the content delivery from the previous stored content while continuing storing or recording the current FM broadcasting content. In the above embodiment, the network #1 whereas the smart personal device and the target device communicate by means may include but not limited to a wireless Ethernet network. However the network #2 is a different network from the network #1 whereas the smart personal device and target device #2 communicate by means may include but not limited to a Bluetooth network. In yet another embodiment, the smart personal device upon user's selection is capable of waking up one of more target devices from the low power sleep state and performs content search operation of its neighboring target devices which has been enabled for such actions. Once the matching criteria is found, the smart personal device will “pull” such content from its neighboring target devices and store on the local storage of the smart personal device without interrupting its current operation of either device. The transfer of the content can be performed using the CPU, memory and the I/O BUS of the neighboring target devices, or if the neighboring target device comprises smart I/O controllers, the transfer of content can optionally be performed using a Direct I/O method of transferring content from the smart storage unit I/O controller to the smart network unit I/O controller independent of the target device's CPU and memory. i.e. under the program control of its Direct I/O Manager, content is transferred from the smart storage unit I/O controller to the network unit I/O controller using the I/O BUS independent of its CPU and main memory. Then the network unit I/O controller transfers the content to the storage unit I/O controller of the smart personal device. The smart personal device with the smart I/O controller have the option to directly transfer the content from its smart network unit I/O controller to the smart storage I/O unit controller independent of its CPU and main memory operate effective under control of the Direct I/O Manager. The Direct I/O method improves the speed performance and reduces power consumption of the device since the CPU and main memory are not active during the content transfer operation. Upon completion, the smart personal device will alert the user that such contents are ready for display at user's convenience. In yet another embodiment, the present invention may, upon its user's command, using “pull” method amongst neighboring target devices as well as content host target devices across the internet; instead of having contents, such as web advertisements, being “pushed” onto the smart personal device without the consent of the user, the smart personal device will operate effectively to block all non-authorized intrusive contents from displaying on the smart personal device or target devices without the consent of the user; instead it offers user an option to specify a desire content criteria for the smart personal device to perform search directly, or indirectly through another intermediary web based service on user's specified criteria. Once the relevant criteria are found, a matched content list will be generated by the smart personal device to enable the user to review the list at one's convenience. If the user elects to view one or more (or all) of the match content from the list, the smart personal device is operable effective to PULL the selected content from the storage area of the various content hosts, which may be over the Internet or target device in its LAN environment. After the completion of the PULL steps, content such as web advertisement is stored onto the storage I/O unit controller of the smart personal device for display at user's convenience. The present invention using “pull content” method for web advertisements over internet as an example, such invention may apply to a variety of contents over the Internet including but not limited to pull relevant books content, relevant news content, relevant sales contents, relevant advertisement promotion through the use of banners, widgets, etc. and user-specified web target services and information sources including but not limited to google.com, facebook.com, youtube.com, amazon.com, uspto.gov, etc. DEACTIVATION: When the smart personal device is no longer proximate to the target device, the target device will automatically be deactivated by the smart personal device in the present invention so the underlining data processing logic including but not limited to the media CPU, main memory, input and output controllers and associated input and output devices and resume in a low power sleep state. Once the target device enters in the low power sleep state the only function running under the low power sleep state is the activation detection logic comprising, but not limited to, RFID, proximity sensor, wake on LAN, and wake on USB units. In one embodiment of a related invention, the target device performs the role of deactivation whereby the target device identifies a smart personal device is no longer located proximate to the target device and performs all operations to deactivate the underlining data processing logic including but not limited to the media CPU, main memory, input and output controllers and associated input and output devices and resume in a low power sleep state.
