Service providers and device manufacturers (e.g., wireless, cellular, etc.) are continually challenged to deliver value and convenience to consumers by, for example, providing compelling network services. Thanks to the portability of mobile devices, more and more users prefer to capture their own video content by mobile device having high quality multimedia collectors such as cameras and microphones to record their daily lives. Mobile devices are also convenient for video reviewing thanks to their mobility. Video sharing is one of the hottest services in current social network services. It allows people to share their information or interesting things through videos. But, current mobile devices and network bandwidth limitations make it difficult for mobile users to enjoy video sharing to its fullest extent.

Information sharing is an interest for many people. This is one reason of why social networking is so popular. Social networking services allow users share their daily experiences with friends and family members. Recently, live video sharing services have been developed and bring new user experiences.
Live video sharing creates a better user experience than video sharing that has an inherent delay such as those that require downloading at a time after the video is recorded. Live video sharing may be beneficial, for example, when a user is travelling, at a social event, or for a live meeting. Live sharing is useful, vivid, and interesting, and is a growing trend for social networking services. In other words, live sharing brings the most direct experience to users.
Video plays an important role in people's information sharing thanks to the fast improvement of mobile multimedia devices. However, sharing video data in a mobile environment is still a nontrivial task because if the limitations of mobile devices and network bandwidths.
As discussed above, though live sharing is desirable to users, many mobile users are unable to enjoy this service because of poor devices or networks. To boost this valuable service, these limitations should be minimized.
To address this problem, a system 100 of
A live video sharing service with multimodal modes would provide a better user experience compared to most conventional video sharing services that are restricted by narrow network bandwidths or cannot be applied in live manner.
Live sharing provides an instant sharing experience with no temporal delay, which is an important feature for social networking users. Users need not store their captured video for sharing purposes. Further, viewers can also know what their friends are doing or going through at that moment. Live sharing may be totally mobile based, which may be achieved by multimodal modes. That is, all the end users can use mobile devices to enjoy a live video service. The users need not transmit or download the shared content to a PC. This feature may be achieved by multimodal selection that allows a user to adjust the sharing content to fit any processability and network bandwidth limitation of the user or the viewer which are major challenges for live video sharing services. Further, live video sharing is easy to share, and combines and abundant context provided by various mobile device sensors (like GPS) and video content analysis. The publication process may be fully automatic, manual, or any combination thereof. While live video sharing is beneficial, there are challenges as discussed above, that must be overcome to enable users to fully enjoy live video sharing services in spite of device limitations and network bandwidth limitations.
Video contains more information than image or audio files. But the data volume of video is also bigger than other media types. Video transmitting, therefore, is the most nontrivial task in mobile environment, and its success mostly depends on the resources of a mobile device and available network bandwidth. To save network bandwidth, key frames, video segments, rendering changes, and audio portions extracted from video, for example, can be transmitted instead of an original video to fit those users who do not require viewing the whole video or just are limited by very narrow bandwidth. This is the core concept of sharing within a multimodal mode service.
To construct such an unsymmetrical and configurable framework/UI is a challenge. Since sharing is live, key frames of video must be extracted when the publisher is shooting the video. In addition, this function may be executed on the publisher's mobile device or on the server, according to a different use case. Thereby the extraction method should be scalable. To improve a user's sharing experience, abundant context may be considered to make sharing process automatic using information provided by sensors on a mobile phone that may be utilized. Furthermore, multimedia content may also be explored to provide more information about the publisher capturing the video.
The system 100 allows users to share their live video content in multimodal manner, such as image, audio, video, etc. to save mobile resources and improve an overall user experience. The system 100 enables at least the following options for a communication session:
1). Original video with live sharing: When a user starts his video shooting, his friends can receive the synchronous content he is capturing by way of a live streaming video.
2). Multimodal options instead of the original video for publishing and receiving/viewing: Multimodal information includes options such as using a key frame mode, an audio mode, a hybrid mode of key frames and audio, a text mode, a key video segment mode, an avatar mode, and a video in scalable resolution mode. Both publisher and receiver can choose their preferred mode for sending and receiving content related to the video that is shot by the sender. The selectable modes may be advantageous to a publisher and/or a receiver of the video content because of a user preference, device limitation, or a limited bandwidth. For example, the viewer can select to just receive key frames of the video if his network bandwidth is low or below a threshold value. Each mode that the system 100 enables may be characterized as follows:
Real-time information may also be extracted during the publisher's shooting of a video. To achieve the multimodal live sharing discussed above, it is a challenge as to how to extract valuable information from the video while shooting. For different modes, there are several strategies:
Choice of location for information extraction and video resolution changes between different sides of the video transmission for different cases. This depends primarily on a publisher's selection. For example, if the publisher chooses a video mode for sharing, all the process tasks can be applied on a server side to save a calculation resource and bandwidth of the publisher. But, if the publisher chooses other multimodal modes for sharing, corresponding calculations have to be taken on his own device, in which case the complexity of any calculation algorithm needs be reduced to fit the end device.
Context collection and analysis is also integrated into our service. This information is utilized to enrich the sharing experience. The following types of context may be considered:
Besides live sharing, the contents that are shared may be stored on a server side. Users can access those contents that are stored anytime, anywhere. Even when the contents are stored, the multimodal modes may also be supported.
As shown in
The UE 101 may incorporate a camera that is either part of the UE 101 or external and may be used as a publishing device. The UE 101 may have a communication API 107a-107n (collectively referred to as communication API 107) for sharing, publishing and/or receiving video content. Captured content is optionally uploaded to the communication management platform 103, which means that the publisher can choose the actual content for publishing, according to his desire or network condition. UE 101 is also able to act as a receiver, with which a user can view other user's videos. Different users may choose different modes during a sharing of video content. The communication management platform 103 may manage several services that are deployed on the server side to support data transmission, storage, analysis, and processing. Any complex computing may executed on the communication management platform 103, which will result in any processed data to be sent to the UE 101. However, the UE 101 may process all of the computing onboard the device and need to require the communication management platform 103 so long as the UE 101 is capable of processing such computations.
In one embodiment, a user of UE 101 may share a live video of a scene around him as a publisher with a user of another UE 101 as a receiver. The publisher may use the communication API 107 to manage the video sharing. The video sharing may be managed through the communication management platform 103 which may process a selection of video sharing modes, or it may automatically change or suggest a change in sharing modes. Such change may be from a live video stream to a key frame mode, or any of the other modes discussed above, among other modes that may become available.
In another embodiment, a user of UE 101 may share a live video of a scene around him as a publisher with a user of another UE 101 as a receiver. The publisher may use the communication API 107 to manage the video sharing. The video sharing may be directly shared as a peer-to-peer experience without interacting with an external communication management platform, but rather, because the communication management platform 103 may also be on board the UE 101 to process a selection of video sharing modes, or it may automatically change or suggest a change in sharing modes. Such change may be from a live video stream to a key frame mode, or any of the other modes discussed above, among other modes that may become available.
In another embodiment, a user of UE 101 may share a live video of a scene around him as a publisher with a user of another UE 101 as a receiver, or may share the video, key frames, or any other result of the modes directly with a social networking service 109. The publisher may use the communication API 107 to manage the video sharing. The video sharing may be directly shared as peer-to-peer without interacting with an external communication management platform, but rather, because the communication management platform 103 may also be onboard the UE 101, or through a communication management platform 103 to process a selection of video sharing modes, or it may automatically change or suggest a change in sharing modes. Such change may be from a live video stream to a key frame mode, or any of the other modes discussed above, among other modes that may become available. The social networking service 109 may automatically or selectively store the communication content for viewing by the publisher, the receiver, or any other contacts that the publisher may want to view the stored communication content.
By way of example, the UE 101, communication management platform 103 and social networking service 109 communicate with each other and other components of the communication network 105 using well known, new or still developing protocols. In this context, a protocol includes a set of rules defining how the network nodes within the communication network 105 interact with each other based on information sent over the communication links. The protocols are effective at different layers of operation within each node, from generating and receiving physical signals of various types, to selecting a link for transferring those signals, to the format of information indicated by those signals, to identifying which software application executing on a computer system sends or receives the information. The conceptually different layers of protocols for exchanging information over a network are described in the Open Systems Interconnection (OSI) Reference Model.
By way of example, the communication network 105 of system 100 includes one or more networks such as a data network, a wireless network, a telephony network, or any combination thereof. It is contemplated that the data network may be any local area network (LAN), metropolitan area network (MAN), wide area network (WAN), a public data network (e.g., the Internet), short range wireless network, or any other suitable packet-switched network, such as a commercially owned, proprietary packet-switched network, e.g., a proprietary cable or fiber-optic network, and the like, or any combination thereof. In addition, the wireless network may be, for example, a cellular network and may employ various technologies including enhanced data rates for global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., worldwide interoperability for microwave access (WiMAX), Long Term Evolution (LTE) networks, code division multiple access (CDMA), wideband code division multiple access (WCDMA), wireless fidelity (WiFi), wireless LAN (WLAN), Bluetooth®, Internet Protocol (IP) data casting, satellite, mobile ad-hoc network (MANET), and the like, or any combination thereof.
The UE 101 is any type of mobile terminal, fixed terminal, or portable terminal including a mobile handset, station, unit, device, multimedia computer, multimedia tablet, Internet node, communicator, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system (PCS) device, personal navigation device, personal digital assistants (PDAs), audio/video player, digital camera/camcorder, positioning device, television receiver, radio broadcast receiver, electronic book device, game device, or any combination thereof, including the accessories and peripherals of these devices, or any combination thereof. It is also contemplated that the UE 101 can support any type of interface to the user (such as “wearable” circuitry, etc.).
Communications between the network nodes are typically effected by exchanging discrete packets of data. Each packet typically comprises (1) header information associated with a particular protocol, and (2) payload information that follows the header information and contains information that may be processed independently of that particular protocol. In some protocols, the packet includes (3) trailer information following the payload and indicating the end of the payload information. The header includes information such as the source of the packet, its destination, the length of the payload, and other properties used by the protocol. Often, the data in the payload for the particular protocol includes a header and payload for a different protocol associated with a different, higher layer of the OSI Reference Model. The header for a particular protocol typically indicates a type for the next protocol contained in its payload. The higher layer protocol is said to be encapsulated in the lower layer protocol. The headers included in a packet traversing multiple heterogeneous networks, such as the Internet, typically include a physical (layer 1) header, a data-link (layer 2) header, an internetwork (layer 3) header and a transport (layer 4) header, and various application (layer 5, layer 6 and layer 7) headers as defined by the OSI Reference Model.
The process continues to step 309 in which the communication management platform 103 processes the capability information and/or the resource availability information to determine one or more available multimodal modes. The extraction of the multimodal information is based, at least in part, on the one or more available multimodal modes. Next, in step 311, the communication management platform 103 determines one or more scene changes in a previously recorded portion of the at least substantially live video data. Then, in step 313, the communication management platform 103 determines one or more key frames based, at least in part, on the one or more scene changes.
The process continues to step 315 in which the communication management platform 103 receives an input for selecting at least one of the one or more key frames. The input may be an indication that a key frame should be automatically selected and sent from one device to another, or a user directed selection that a key frame should be sent from one device to another. Next, in step 317, the communication management platform 103 causes, at least in part, an exchange of a portion of the at least substantially live video data associated with the at least one of the one or more key frames. Then, in step 319, the communication management platform 103 processes the previously recorded portion the at least substantially live video data and/or concurrently recorded audio data to determine one or more audio segments based, at least in part, on one or more audio selection criteria. The audio data may have at least in part the one or more audio segments. The process continues to step 321 in which the communication management platform 103 processes the capability information and/or the resource availability information to determine one or more reduced resolution video encoding parameters. Then, in step 323, the communication management platform 103 causes, at least in part, a generation of the reduced-resolution video data based, at least in part, on the one or more reduced resolution video encoding parameters.
Next, in step 325, the communication management platform 103 determines context information associated with the device, the one or more other devices, the at least substantially live video data, or a combination thereof. The multimodal information includes, at least in part, the context information. Then, in step 327, to aid in speeding up any of the other steps or processes of the process, the communication management platform 103 causes a storage of the at least substantially live video data and the multimodal information for subsequent access.
Several algorithms are involved in this service, mainly involving instant key frame extraction, human voice detection and recognition, human face recognition, etc. These algorithms are usually executed on an external communication management platform 103 as discussed above to simplify the calculation on user's mobile phone. But if the publisher doesn't share an entire video, or the UE 101 is capable of processing the algorithm without consulting an external communication management platform, the corresponding algorithm maybe executed on the UE 101.
For audio extraction, the simplest mode that users can choose is just to transfer the audio data captured by the publisher's microphone. Or users can select another mode which filters out silent and meaningless noise segment to save bandwidth. In this mode, the most important audio segments are those which contain human voice; in addition, some audio events are also considered meaningful, such as wedding march, birthday song, yelp, etc.
For key frame extraction, there are three conditions that may trigger new key frame generation and transferring.
For context integration, some additional options may be made available such as route/map information, people involved with one another, recommendations for places to go and things to do, etc. Examples of context that may be considered are as follows:
The processes described herein for enhancing a communication session may be advantageously implemented via software, hardware, firmware or a combination of software and/or firmware and/or hardware. For example, the processes described herein, may be advantageously implemented via processor(s), Digital Signal Processing (DSP) chip, an Application Specific Integrated Circuit (ASIC), Field Programmable Gate Arrays (FPGAs), etc. Such exemplary hardware for performing the described functions is detailed below.
A bus 710 includes one or more parallel conductors of information so that information is transferred quickly among devices coupled to the bus 710. One or more processors 702 for processing information are coupled with the bus 710.
A processor (or multiple processors) 702 performs a set of operations on information as specified by computer program code related to enhance a communication session. The computer program code is a set of instructions or statements providing instructions for the operation of the processor and/or the computer system to perform specified functions. The code, for example, may be written in a computer programming language that is compiled into a native instruction set of the processor. The code may also be written directly using the native instruction set (e.g., machine language). The set of operations include bringing information in from the bus 710 and placing information on the bus 710. The set of operations also typically include comparing two or more units of information, shifting positions of units of information, and combining two or more units of information, such as by addition or multiplication or logical operations like OR, exclusive OR (XOR), and AND. Each operation of the set of operations that can be performed by the processor is represented to the processor by information called instructions, such as an operation code of one or more digits. A sequence of operations to be executed by the processor 702, such as a sequence of operation codes, constitute processor instructions, also called computer system instructions or, simply, computer instructions. Processors may be implemented as mechanical, electrical, magnetic, optical, chemical or quantum components, among others, alone or in combination.
Computer system 700 also includes a memory 704 coupled to bus 710. The memory 704, such as a random access memory (RAM) or any other dynamic storage device, stores information including processor instructions for enhancing a communication session. Dynamic memory allows information stored therein to be changed by the computer system 700. RAM allows a unit of information stored at a location called a memory address to be stored and retrieved independently of information at neighboring addresses. The memory 704 is also used by the processor 702 to store temporary values during execution of processor instructions. The computer system 700 also includes a read only memory (ROM) 706 or any other static storage device coupled to the bus 710 for storing static information, including instructions, that is not changed by the computer system 700. Some memory is composed of volatile storage that loses the information stored thereon when power is lost. Also coupled to bus 710 is a non-volatile (persistent) storage device 708, such as a magnetic disk, optical disk or flash card, for storing information, including instructions, that persists even when the computer system 700 is turned off or otherwise loses power.
Information, including instructions for enhancing a communication session, is provided to the bus 710 for use by the processor from an external input device 712, such as a keyboard containing alphanumeric keys operated by a human user, a microphone, an Infrared (IR) remote control, a joystick, a game pad, a stylus pen, a touch screen, or a sensor. A sensor detects conditions in its vicinity and transforms those detections into physical expression compatible with the measurable phenomenon used to represent information in computer system 700. Other external devices coupled to bus 710, used primarily for interacting with humans, include a display device 714, such as a cathode ray tube (CRT), a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a plasma screen, or a printer for presenting text or images, and a pointing device 716, such as a mouse, a trackball, cursor direction keys, or a motion sensor, for controlling a position of a small cursor image presented on the display 714 and issuing commands associated with graphical elements presented on the display 714. In some embodiments, for example, in embodiments in which the computer system 700 performs all functions automatically without human input, one or more of external input device 712, display device 714 and pointing device 716 is omitted.
In the illustrated embodiment, special purpose hardware, such as an application specific integrated circuit (ASIC) 720, is coupled to bus 710. The special purpose hardware is configured to perform operations not performed by processor 702 quickly enough for special purposes. Examples of ASICs include graphics accelerator cards for generating images for display 714, cryptographic boards for encrypting and decrypting messages sent over a network, speech recognition, and interfaces to special external devices, such as robotic arms and medical scanning equipment that repeatedly perform some complex sequence of operations that are more efficiently implemented in hardware.
Computer system 700 also includes one or more instances of a communications interface 770 coupled to bus 710. Communication interface 770 provides a one-way or two-way communication coupling to a variety of external devices that operate with their own processors, such as printers, scanners and external disks. In general the coupling is with a network link 778 that is connected to a local network 780 to which a variety of external devices with their own processors are connected. For example, communication interface 770 may be a parallel port or a serial port or a universal serial bus (USB) port on a personal computer. In some embodiments, communications interface 770 is an integrated services digital network (ISDN) card or a digital subscriber line (DSL) card or a telephone modem that provides an information communication connection to a corresponding type of telephone line. In some embodiments, a communication interface 770 is a cable modem that converts signals on bus 710 into signals for a communication connection over a coaxial cable or into optical signals for a communication connection over a fiber optic cable. As another example, communications interface 770 may be a local area network (LAN) card to provide a data communication connection to a compatible LAN, such as Ethernet. Wireless links may also be implemented. For wireless links, the communications interface 770 sends or receives or both sends and receives electrical, acoustic or electromagnetic signals, including infrared and optical signals, that carry information streams, such as digital data. For example, in wireless handheld devices, such as mobile telephones like cell phones, the communications interface 770 includes a radio band electromagnetic transmitter and receiver called a radio transceiver. In certain embodiments, the communications interface 770 enables connection to the communication network 105 for enhancing a communication session to the UE 101.
The term “computer-readable medium” as used herein refers to any medium that participates in providing information to processor 702, including instructions for execution. Such a medium may take many forms, including, but not limited to computer-readable storage medium (e.g., non-volatile media, volatile media), and transmission media. Non-transitory media, such as non-volatile media, include, for example, optical or magnetic disks, such as storage device 708. Volatile media include, for example, dynamic memory 704. Transmission media include, for example, twisted pair cables, coaxial cables, copper wire, fiber optic cables, and carrier waves that travel through space without wires or cables, such as acoustic waves and electromagnetic waves, including radio, optical and infrared waves. Signals include man-made transient variations in amplitude, frequency, phase, polarization or other physical properties transmitted through the transmission media. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, CDRW, DVD, any other optical medium, punch cards, paper tape, optical mark sheets, any other physical medium with patterns of holes or other optically recognizable indicia, a RAM, a PROM, an EPROM, a FLASH-EPROM, an EEPROM, a flash memory, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read. The term computer-readable storage medium is used herein to refer to any computer-readable medium except transmission media.
Logic encoded in one or more tangible media includes one or both of processor instructions on a computer-readable storage media and special purpose hardware, such as ASIC 720.
Network link 778 typically provides information communication using transmission media through one or more networks to other devices that use or process the information. For example, network link 778 may provide a connection through local network 780 to a host computer 782 or to equipment 784 operated by an Internet Service Provider (ISP). ISP equipment 784 in turn provides data communication services through the public, world-wide packet-switching communication network of networks now commonly referred to as the Internet 790.
A computer called a server host 792 connected to the Internet hosts a process that provides a service in response to information received over the Internet. For example, server host 792 hosts a process that provides information representing video data for presentation at display 714. It is contemplated that the components of system 700 can be deployed in various configurations within other computer systems, e.g., host 782 and server 792.
At least some embodiments of the invention are related to the use of computer system 700 for implementing some or all of the techniques described herein. According to one embodiment of the invention, those techniques are performed by computer system 700 in response to processor 702 executing one or more sequences of one or more processor instructions contained in memory 704. Such instructions, also called computer instructions, software and program code, may be read into memory 704 from another computer-readable medium such as storage device 708 or network link 778. Execution of the sequences of instructions contained in memory 704 causes processor 702 to perform one or more of the method steps described herein. In alternative embodiments, hardware, such as ASIC 720, may be used in place of or in combination with software to implement the invention. Thus, embodiments of the invention are not limited to any specific combination of hardware and software, unless otherwise explicitly stated herein.
The signals transmitted over network link 778 and other networks through communications interface 770, carry information to and from computer system 700. Computer system 700 can send and receive information, including program code, through the networks 780, 790 among others, through network link 778 and communications interface 770. In an example using the Internet 790, a server host 792 transmits program code for a particular application, requested by a message sent from computer 700, through Internet 790, ISP equipment 784, local network 780 and communications interface 770. The received code may be executed by processor 702 as it is received, or may be stored in memory 704 or in storage device 708 or any other non-volatile storage for later execution, or both. In this manner, computer system 700 may obtain application program code in the form of signals on a carrier wave.
Various forms of computer readable media may be involved in carrying one or more sequence of instructions or data or both to processor 702 for execution. For example, instructions and data may initially be carried on a magnetic disk of a remote computer such as host 782. The remote computer loads the instructions and data into its dynamic memory and sends the instructions and data over a telephone line using a modem. A modem local to the computer system 700 receives the instructions and data on a telephone line and uses an infra-red transmitter to convert the instructions and data to a signal on an infra-red carrier wave serving as the network link 778. An infrared detector serving as communications interface 770 receives the instructions and data carried in the infrared signal and places information representing the instructions and data onto bus 710. Bus 710 carries the information to memory 704 from which processor 702 retrieves and executes the instructions using some of the data sent with the instructions. The instructions and data received in memory 704 may optionally be stored on storage device 708, either before or after execution by the processor 702.
In one embodiment, the chip set or chip 800 includes a communication mechanism such as a bus 801 for passing information among the components of the chip set 800. A processor 803 has connectivity to the bus 801 to execute instructions and process information stored in, for example, a memory 805. The processor 803 may include one or more processing cores with each core configured to perform independently. A multi-core processor enables multiprocessing within a single physical package. Examples of a multi-core processor include two, four, eight, or greater numbers of processing cores. Alternatively or in addition, the processor 803 may include one or more microprocessors configured in tandem via the bus 801 to enable independent execution of instructions, pipelining, and multithreading. The processor 803 may also be accompanied with one or more specialized components to perform certain processing functions and tasks such as one or more digital signal processors (DSP) 807, or one or more application-specific integrated circuits (ASIC) 809. A DSP 807 typically is configured to process real-world signals (e.g., sound) in real time independently of the processor 803. Similarly, an ASIC 809 can be configured to performed specialized functions not easily performed by a more general purpose processor. Other specialized components to aid in performing the inventive functions described herein may include one or more field programmable gate arrays (FPGA), one or more controllers, or one or more other special-purpose computer chips.
In one embodiment, the chip set or chip 800 includes merely one or more processors and some software and/or firmware supporting and/or relating to and/or for the one or more processors.
The processor 803 and accompanying components have connectivity to the memory 805 via the bus 801. The memory 805 includes both dynamic memory (e.g., RAM, magnetic disk, writable optical disk, etc.) and static memory (e.g., ROM, CD-ROM, etc.) for storing executable instructions that when executed perform the inventive steps described herein to enhance a communication session. The memory 805 also stores the data associated with or generated by the execution of the inventive steps.
Pertinent internal components of the telephone include a Main Control Unit (MCU) 903, a Digital Signal Processor (DSP) 905, and a receiver/transmitter unit including a microphone gain control unit and a speaker gain control unit. A main display unit 907 provides a display to the user in support of various applications and mobile terminal functions that perform or support the steps of enhancing a communication session. The display 907 includes display circuitry configured to display at least a portion of a user interface of the mobile terminal (e.g., mobile telephone). Additionally, the display 907 and display circuitry are configured to facilitate user control of at least some functions of the mobile terminal. An audio function circuitry 909 includes a microphone 911 and microphone amplifier that amplifies the speech signal output from the microphone 911. The amplified speech signal output from the microphone 911 is fed to a coder/decoder (CODEC) 913.
A radio section 915 amplifies power and converts frequency in order to communicate with a base station, which is included in a mobile communication system, via antenna 917. The power amplifier (PA) 919 and the transmitter/modulation circuitry are operationally responsive to the MCU 903, with an output from the PA 919 coupled to the duplexer 921 or circulator or antenna switch, as known in the art. The PA 919 also couples to a battery interface and power control unit 920.
In use, a user of mobile terminal 901 speaks into the microphone 911 and his or her voice along with any detected background noise is converted info an analog voltage. The analog voltage is then converted into a digital signal through the Analog to Digital Converter (ADC) 923. The control unit 903 routes the digital signal into the DSP 905 for processing therein, such as speech encoding, channel encoding, encrypting, and interleaving. In one embodiment, the processed voice signals are encoded, by units not separately shown, using a cellular transmission protocol such as enhanced data rates for global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., microwave access (WiMAX), Long Term Evolution (LTE) networks, code division multiple access (CDMA), wideband code division multiple access (WCDMA), wireless fidelity (WiFi), satellite, and the like, or any combination thereof.
The encoded signals are then routed to an equalizer 925 for compensation of any frequency-dependent impairments that occur during transmission though the air such as phase and amplitude distortion. After equalizing the bit stream, the modulator 927 combines the signal with a RF signal generated in the RF interface 929. The modulator 927 generates a sine wave by way of frequency or phase modulation. In order to prepare the signal for transmission, an up-converter 931 combines the sine wave output from the modulator 927 with another sine wave generated by a synthesizer 933 to achieve the desired frequency of transmission. The signal is then sent through a PA 919 to increase the signal to an appropriate power level. In practical systems, the PA 919 acts as a variable gain amplifier whose gain is controlled by the DSP 905 from information received from a network base station. The signal is then filtered within the duplexer 921 and optionally sent to an antenna coupler 935 to match impedances to provide maximum power transfer. Finally, the signal is transmitted via antenna 917 to a local base station. An automatic gain control (AGC) can be supplied to control the gain of the final stages of the receiver. The signals may be forwarded from there to a remote telephone which may be another cellular telephone, any other mobile phone or a land-line connected to a Public Switched Telephone Network (PSTN), or other telephony networks.
Voice signals transmitted to the mobile terminal 901 are received via antenna 917 and immediately amplified by a low noise amplifier (LNA) 937. A down-converter 939 lowers the carrier frequency while the demodulator 941 strips away the RF leaving only a digital bit stream. The signal then goes through the equalizer 925 and is processed by the DSP 905. A Digital to Analog Converter (DAC) 943 converts the signal and the resulting output is transmitted to the user through the speaker 945, all under control of a Main Control Unit (MCU) 903 which can be implemented as a Central Processing Unit (CPU).
The MCU 903 receives various signals including input signals from the keyboard 947. The keyboard 947 and/or the MCU 903 in combination with other user input components (e.g., the microphone 911) comprise a user interface circuitry for managing user input. The MCU 903 runs a user interface software to facilitate user control of at least some functions of the mobile terminal 901 to enhance a communication session. The MCU 903 also delivers a display command and a switch command to the display 907 and to the speech output switching controller, respectively. Further, the MCU 903 exchanges information with the DSP 905 and can access an optionally incorporated SIM card 949 and a memory 951. In addition, the MCU 903 executes various control functions required of the terminal. The DSP 905 may, depending upon the implementation, perform any of a variety of conventional digital processing functions on the voice signals. Additionally, DSP 905 determines the background noise level of the local environment from the signals detected by microphone 911 and sets the gain of microphone 911 to a level selected to compensate for the natural tendency of the user of the mobile terminal 901.
The CODEC 913 includes the ADC 923 and DAC 943. The memory 951 stores various data including call incoming tone data and is capable of storing other data including music data received via, e.g., the global Internet. The software module could reside in RAM memory, flash memory, registers, or any other form of writable storage medium known in the art. The memory device 951 may be, but not limited to, a single memory, CD, DVD, ROM, RAM, EEPROM, optical storage, magnetic disk storage, flash memory storage, or any other non-volatile storage medium capable of storing digital data.
An optionally incorporated SIM card 949 carries, for instance, important information, such as the cellular phone number, the carrier supplying service, subscription details, and security information. The SIM card 949 serves primarily to identify the mobile terminal 901 on a radio network. The card 949 also contains a memory for storing a personal telephone number registry, text messages, and user specific mobile terminal settings.
While the invention has been described in connection with a number of embodiments and implementations, the invention is not so limited but covers various obvious modifications and equivalent arrangements, which fall within the purview of the appended claims. Although features of the invention are expressed in certain combinations among the claims, it is contemplated that these features can be arranged in any combination and order.
