Description:
TECHNICAL FIELD 
       [0001]    The present disclosure relates to the field of communication and information, and in particular to a method, transferring-in apparatus, transferring-out apparatus and related system for transferring digital media content playback between digital media equipment. 
       BACKGROUND 
       [0002]    The development of digital media and networks enriches entertainment experiences in people&#39;s daily lives. An existing technology enables people to watch high-definition Televisions (TV) of which sources may be digital compact discs, cable TVs, the Internet and the like at home, experience stereo, 5.1-channel, 7.1-channel and even more realistic sound effects and enjoy these experiences by virtue of flat-panel TVs and mobile phones. By the existing technology, people may also transfer digital contents to play between different equipment through networks and play the digital contents, for example, controlling the switching of programs of previous channels and next channels, through remote controllers and gesture control equipment. 
         [0003]    At present, a common method for controlling multiple equipment is to use respective remote controllers of the equipment for control, but the remote controllers are often not universal. Most of remote controllers do not have a network function, for example, an existing TV and audio equipment; but there are also some remote controllers supporting networks, for example, software supporting an interworking protocol is loaded on equipment (such as a mobile phone and a TV) with calculation and network capabilities to control another equipment. Gesture control is a relatively novel manner at present: a camera on equipment monitors a gesture, performs analysis and identification, and finally converts the gesture into control over the equipment. 
         [0004]    Along with the development of technology, requirements on content playing sharing and transferring among multiple equipment grow, and the abovementioned control manners are not so convenient, in which people need to select remote controllers corresponding to the equipment from a heap of remote controllers and continuously replace the remote controllers for controlling different equipment, or only people familiar with basic computer operation can control the equipment by operating TVs and mobile phones, or a single piece of equipment is controlled by a simple gesture. People expect to control the playback sharing and playback transferring of contents by virtue of simpler and more natural control manners. 
         [0005]    If a simpler and more natural control manner can be provided to realize control over functions of playing transferring, cooperative playing and the like of contents between equipment and an accurate result can be obtained by such a control manner, entertainment lives of people may be easier and more enjoyable; and in addition, people also want to understand and realize new equipment functions more easily when mastering the new equipment functions.

The network interfaces are responsible for sending and receiving at various networks the network messages. 
         [0085]    In the embodiment, the movements which can be identified by TV 1  are as follows respectively: 
         [0086]    first group: 
         [0087]    1) grabbing: the user makes a grabbing movement or a pinching movement with a hand at the camera; and 
         [0088]    2) taking-back: the user makes a taking-back movement with a palm and an arm at the camera: the arm is straightened at the camera, and then the forearm is bent back towards a midline direction of a body of the user. 
         [0089]    In the embodiment, the movements which can be identified by TV 2  are as follows respectively: 
         [0090]    second group: 
         [0091]    1) throwing: the user makes a throwing movement with a hand at the camera of TV 2 ; 
         [0092]    2) releasing: the user keeps a grabbing or pinching gesture in the first group, and then makes a releasing movement with a hand at the camera of TV 2 ; 
         [0093]    3) pointing: the user makes a pointing movement at the camera of TV 2 ; and 
         [0094]    4) spreading; if TV 2  has a touch screen, five fingers are gathered, and then the fingers are spread on the touch screen. 
         [0095]    In terms of identification of meanings of the movements with a camera, a histogram method or a hidden Markov model method is adopted for the identification of the gestures. At first, a gesture of the user needs to fall within a capturing range of the camera, so that the camera can generate a gesture video, and send the gesture video to the identification function sub-module; then the identification function sub-module identifies positions of the hand in gesture images in the video by virtue of colours, or contours, or structured light analysis or the like, detects and divides gesture objects, extracts gesture characteristics, and tracks the gesture; and then finger direction and movement direction sequences are processed to finally identify the gesture completely, and the meanings of the movements of the user may be determined by adopting methods of comparison with a predefined gesture space and the like. 
         [0096]    Besides the abovementioned gestures, movements such as an eyeball movement and a body gesture may further be made. 
         [0097]    Digital media content transfer control can be respectively finished by selecting one movement from each of the two groups of movements for combination, for example, the movement 1) in the first group is selected to be made on TV 1  at first, and then the movement 2) in the second group is made at the camera of TV 2 . 
         [0098]    The network service capabilities of TV 1  and TV 2  include: 
         [0099]    1) mutual discovery of TV 1  and TV 2  through a network; 
         [0100]    2) cooperative control operation through the network; and 
         [0101]    3) transmission of a digital media content. 
         [0102]    TV 1  sends the first message for notifying TV 2  to get ready to receive or identify the body movement (such as a gesture) after receiving or identifying the body movement of preparing to transfer the digital media content playback, the message including first positional relationship information (such as gesture position information) between TV 1  and the user. Then, TV 2  sends the second message to notify TV 1  that TV 2  has been ready to receive the digital media content playback after receiving or identifying the body movement of transferring the digital media content playback to TV 2 , the second message including second positional relationship information (such as gesture position information) between TV 2  and the user. Finally, TV 1  confirms the transfer of the digital media content playback to TV 2  to finish the transfer of the playback. 
         [0103]    The gesture position information may be an angle parameter of the gesture and the equipment, or may also be a distance parameter between the gesture and the equipment. Therefore, when there exist multiple first equipment and/or multiple second equipment, local equipment can determine optimal opposite equipment according to the gesture position information of the opposite equipment and respond to the message. 
         [0104]      FIG. 3  is a schematic diagram of an angle between a gesture and a camera according to an embodiment of the present disclosure. In consideration that there may be more than one first equipment or second equipment in a scenario of the present disclosure, as shown in  FIG. 3 , an operating user is not required to accurately regulate own position and make the gesture in front of each equipment. The condition that there are two second equipment in the system is taken as an example, as shown in  FIG. 3 , there are two equipment TV 1  and TV 2 , and the equipment forms an angle with a gesture of the user by taking the user as a coordinate centre. In the embodiment, when the equipment identifies the gesture, the angle and distance between an extending line of the gesture of the user and the camera can be identified, which can be implemented by virtue of technologies of measurement with additional infrared light, laser measurement, measurement and the like in the existing technology. 
         [0105]    In  FIG. 3 , any equipment with an identification function identifies an arm at first, the other endpoint of the arm is taken as a coordinate origin, an angle is changed from 0° to 360° if a palm (fingers) moves (move) from left to right (observed by the user), and the angle is changed from 0° to 180° if the palm (fingers) moves (move) from top to bottom. Here, it is the included angle between a camera-hand line and a hand-arm line in a triangle formed by the camera, the hand and the other endpoint of the arm, which is to be calculated by the equipment. If the included angle is larger, it is indicated that the gesture more tends to point to the camera in the triangle, that is, the gesture more tends to point to the equipment where the camera is. The magnitude of the angle and the corresponding meaning are as follows: 
         [0106]    &lt;0°: a hand does not point to the equipment; 
         [0107]    0°-90°: a hand maybe points to the equipment; 
         [0108]    90°-180°: in such a situation, the hand, the arm and the camera more and more tend to be located in the same straight line, which means that the hand probably point to the equipment; and 
         [0109]    180°: in such a situation, the hand, the arm and the camera are located in the same straight line, and the hand undoubtedly points to the equipment. 
         [0110]    As another embodiment, in  FIG. 3 , the coordinate origin is still specified as above, and here, another point may also be selected as the coordinate origin. It is specified that the angle is changed from 0° to 360° if the palm (fingers) moves (move) from left to right (observed by the user) and the angle is changed from 0° to 180° if the palm (fingers) moves (move) from top to bottom, and the direction here may also be selected. It is the lengths of the camera-hand line, the hand-arm line and the line formed by the other endpoint of the arm and the camera in the triangle formed by the camera, the hand and the other endpoint of the arm, which are to be calculated by the equipment; and in terms of length calculation, the identification sub-module can directly measure the three lengths, and can also proportionally calculate the lengths after measuring reference distances. 
         [0111]    Optionally, the positional relationship information may further include the distance between the hand or arm and the camera. 
         [0112]      FIG. 4  is a flowchart of network messages in a control method according to a first embodiment of the present disclosure, and as shown in  FIG. 4 , the flow includes the following steps. 
         [0113]    In  FIG. 4 , first equipment is TV 1 , and there are two second equipment which are TV 2  and an Audio System respectively. In the embodiment, a digital media content is played on TV 1 , a user controls the display media content playback to be transferred from TV 1  to TV 2 , and for the user, scenarios and experiences are as follows: when grabbing and taking-back movements are made on a screen of TV 1  on which a video is played and then the hand makes a throwing movement towards a camera of TV 2 , the digital media content originally played on TV 1  is played on TV 2 , and the user can directly watch the video content played on TV 2 . In such a process, the user is not required to identify a menu on the screen, the user is also not required to click a screen button and the like, and the user is further not required to use a remote controller. During the operation of the user with a gesture, the user is not required to operate directly at the camera of TV 2 , and the user is only required to make the gesture approximately at TV 2 , so that worry about a conflict happening during the transfer of the digital media content playback of multiple equipment (for example, there is further Audio System) with an identification function is eliminated. 
         [0114]    In each embodiment, the equipment is connected with one another through a network, can communicate with one another, and can also have a mutual discovery capability. 
         [0115]    Specifically, a processing flow of such a function includes the following steps. 
         [0116]    Step  401  is that a user demonstrates a first movement on TV 1 , and TV 1  identifies the movement, and determines a transfer intention of the user, namely identifies that current video playback on TV 1  is to be transferred to another equipment to play. 
         [0117]    Here, the first movement may be any movement in the first group of movements. TV 1  may support at least one movement in the first group of movements. The identification of the movements is predefined in combination with the context in TV 1 , and a part of movements are identified in combination with an image identification algorithm, so that TV 1  can identify the meaning of the movement, namely the current video playback is to be transferred to another equipment to play. 
         [0118]    The step depends on a triggering capability in digital media content playback transfer of TV 1 , i.e. the first equipment, and the triggering capability means that TV 1  can receive or identify the body movement of preparing to transfer the playback, and trigger the other equipment to obtain an instruction of preparing to transfer the digital media content playback. 
         [0119]    In Step  401 , the camera of the first equipment can keep monitoring and identifying all the time (because the first equipment might receive a content from another equipment), or may also start a monitoring function of the camera by virtue of a starting gesture or another starting manner. In Step  401 , the first equipment finishes receiving the instruction of preparing to transfer the digital media content playback, or, the first equipment finishes identifying the instruction (such as the grabbing movement) of preparing to transfer the digital media content playback. 
         [0120]    Step  402  includes that TV 1  broadcasts a first message READY PLEASE after identifying the body movement of the user for transferring out the digital media content playback. 
         [0121]    TV 1  identifies the movement, starts a network service function after identifying the intention of transferring the digital media content playback, and sends a broadcast/multicast message at a predetermined address and port, the message including information for notifying the other equipment to get ready to identify and receive the movement. The message is called READY PLEASE in the present disclosure, and is configured to notify the other equipment to get ready for identification and reception, and notify a digital media content playing capability of TV 1 . The first message includes information as follows: 
         [0122]    the name, address and port of the TV 1 , which are the sending address of the message READY PLEASE for the digital media content playback as well as an address for subsequently receiving a preparation response message; 
         [0123]    an identified gesture positional relationship, which includes data about the positional relationship between the camera and the gesture such as the angle and the distance of the gesture relative to the camera; an identification method, representation method and the like may adopt the methods shown in  FIG. 3 , which may further adopt other data for representing the positional relationship; 
         [0124]    indication of the type of the digital media content, which indicates that the digital media content may be one of following: an image, a movement image, a sound a desktop or any combinations thereof; 
         [0125]    an attribute of the digital media content, which includes an image coding manner when the digital media content is an image, includes an image coding manner, a frame rate and the like when the digital media content is a movement image, includes a sound coding manner, and/or a sampling rate and the like when the digital media content is a sound, includes the size of the desktop, a resolution and the like when the digital media content is a desktop, and includes a corresponding parameter of each type in the combination when the digital media content is a combination; 
         [0126]    transport protocol parameters for the sending of the digital media content, which include the address, the port and a set of other protocol parameters, wherein the parameters listed here are used for sending the digital media content when the transfer of the digital media content is finally confirmed; and 
         [0127]    a timeout duration, which represents the valid time of the message READY PLEASE, that is, the transfer intention is invalid (cancelled) after a specified time. 
         [0128]    Before Step  402  is finished, the TV 2  and Audio System can finish mutual connection between TV 1  and each of TV 2  and Audio System by virtue of their network capabilities, and after TV  1  receives the instruction indicative of having triggered the preparation for transferring the digital media content playback, T 1  can also by virtue of a network capability, send a message instruction to notify the other equipment (including TV 2  and Audio System) to get ready to receive or identify the gesture through the network, that is, the other equipment is required to confirm whether the transfer of the digital media content playback can be received or not. 
         [0129]    In brief, in Step  402 , the first equipment TV 1  sends the instruction to notify the other equipment to confirm whether the transfer of the digital media content playback can be received or not. 
         [0130]    Step  403  includes that the second equipment TV 2  and Audio System identify a second movement. 
         [0131]    The second movement may be any movement in the second group of movements, and TV 2  and Audio System may support at least one movement in the second group of movements. The identification of the movements is predefined in combination with the context in TV 2  and Audio System, and in the context, the camera starts enabling the identification function after the first message of TV 1  is received, and the identification of the movement is implemented in combination with the image identification algorithm, so that TV 2  and Audio System can identify the meaning of the movement, namely the current video playback is to be transferred to the local equipment to play. 
         [0132]    It should be noted that there exist multiple second equipment in the embodiment, that is, there may be multiple TV equipment and/or set-top box equipment and/or sound equipment and the like with the abovementioned function, two equipment TV 2  and Audio System are adopted, and both TV 2  and Audio System can identify the second movement. 
         [0133]    In Step  403 , the second equipment identifies that the digital media content playback is to be transferred to the second equipment to play. 
         [0134]    Step  404  includes that after the second equipment TV 2  and Audio System identify the body movement of the user for transferring the digital media content playback, TV 2  and Audio System send second messages: PAIRED OK or PAIR FAILURED. 
         [0135]    In Step  404 , there are two kinds of second messages: the first is PAIRED OK, representing that the equipment can receive the digital media content playback; and the other is PAIR FAILED, representing that the equipment cannot receive the transferred digital media content playback although identifying the movement. In the embodiment, TV 2  and Audio System send PAIRED OK to TV 1 . 
         [0136]    After TV 2  and Audio System identify the movement directed to the two equipment, namely identifying the intention of transferring the digital media content playback to the two equipment; if the two equipment can receive the digital media content playback indicated in the first message sent by TV 1 , the network service function is enabled, and the second message PAIRED OK is sent to TV 1  at the pre-specified address and port, the second message including information for answering TV 1 : the local equipment is confirmed to receive the digital media content playback. If the two equipment cannot receive the digital media content playback indicated in the first message sent by TV 1 , the network service function is enabled, and the second message PAIR FAILURE is sent to TV 1  at the pre-specified address and port, the message including information for answering TV 1 : the two equipment cannot receive the digital media content playback for what reason. Of course, TV 2  and Audio System may also not respond to the message of TV 1 , namely not sending any message. 
         [0137]    TV 2  and Audio System can send the second messages to only one TV 1 . That is, TV 2  and Audio System can receive first messages sent by multiple first equipment like TV 1 , then TV 2  and Audio System determine and select the most accurate first equipment according to gesture position information given by the first equipment in the received first messages, and respond to the selected first equipment with the second message PAIRED OK. 
         [0138]    The step that TV 2  and Audio System make a determination according to the gesture position information given by multiple first equipment can be processed according to the embodiment shown in  FIG. 3 , for example, angle data given by a plurality of TVs 1  is as follows: 
         [0139]    TV 1 (1): 100° 
         [0140]    TV 1 (2): 170° 
         [0141]    TV 1 (3): 80° 
         [0142]    At this time, TV 2  and Audio System select TV 1 ( 2 ) as target equipment, and send preparation response messages. 
         [0143]    If it is a distance parameter rather than an angle parameter given by TV 1 , TV 2  and Audio System perform calculation according to a trigonometric formula, and select TV 1  after calculating the angle. 
         [0144]    Preferably, the second message PAIRED OK includes the digital media content playing capability of the second equipment, including, for example, information as follows: 
         [0145]    the name, address and port of the local equipment, which are the sending address of the message PAIRED OK as well as an address for subsequent response interaction; 
         [0146]    an identified gesture positional relationship: which includes data about the positional relationship between the gesture and the camera such as the angle and the distance of the gesture relative to the camera, wherein an identification method, representation method and the like may adopt the methods shown in  FIG. 3 , which may further adopt other data for representing the positional relationship; 
         [0147]    indication of a type of the receivable digital media content: which indicates that the digital media content may be one of following: an image, a movement image, a sound a desktop or any combinations thereof, which is the type of the content confirmed by TV 2  and Audio System to TV 1 ; 
         [0148]    an attribute of the digital media content: which includes an image coding manner when the digital media content is an image, includes an image coding manner, a frame rate and the like when the digital media content is a movement image, includes a sound coding manner, and/or a sampling rate and the like when the digital media content is a sound, and includes the size of the desktop, a resolution and the like when the digital media content is a desktop, which is the attribute of the content confirmed by TV 2  to TV 1 ; 
         [0149]    a transport protocol for receiving the sent digital media content: which includes the address, the port and a set of other protocol parameters; the parameters listed here are used for reception if the transfer of the digital media content is finally established; it is confirmation of the transport protocol for the content by TV 2  and Audio System to TV 1 ; and 
         [0150]    a timeout duration: which represents the valid time of the message, that is, the intension of receiving the digital media content playback is invalid (cancelled) after a specified time. 
         [0151]    In Step  404 , the second equipment confirms that the second equipment have been ready to receive the digital media content playback to the first equipment. 
         [0152]    Step  405  includes that TV 1  gives a response to the message PAIRED OK: PAIRED CONFIRM or PAIR REFUSED. 
         [0153]    TV 1  sends a third message PAIRED CONFIRM or PAIR REFUSED to TV 2  or Audio System, PAIRED CONFIRM being sent by TV 1  to TV 2  or Audio System to which TV 1  is willing to send the digital media content playback, or PAIR REFUSED being sent by TV 1  to TV 2  or Audio System to which TV 1  may not transfer the digital media content playback. In the embodiment, TV 1  sends PAIRED CONFIRM to TV 2 , and sends PAIR REFUSED to Audio System, namely TV 1  selects to transfer the digital media content to TV 2  to play. 
         [0154]    TV 1  receives PAIRED OK from multiple second equipment such as TV 2  and Audio System in  FIG. 4 , and determines the optimal second equipment according to the gesture position information identified by the second equipment. For example, according to the embodiment shown in  FIG. 3 , TV 1  selects TV 2  or Audio System according to the straight line with the largest angle and/or minimum distance reported in the received preparation completion message, and gives a response to the selected TV 2  or Audio System with PAIR CONFIRM. 
         [0155]    For example, if angle data given by TV 2  and Audio System is as follows: 
         [0156]    TV 2 (1): 100° 
         [0157]    TV 2 (2): 170° 
         [0158]    TV 1  selects TV 2 ( 2 ) as target equipment, and gives a response with a message. 
         [0159]    If it is a distance parameter rather than an angle parameter given by TV 2  or Audio System, TV 1  may perform calculation according to the trigonometric formula, and select the target equipment after calculating the angle. 
         [0160]    Of course, TV 1  may also provide an operating interface for the user to select the target equipment, for example, options are listed on the screen, the user selects the equipment, and then the subsequent flow is continued. 
         [0161]    Step  406  includes that the current digital media content playback of TV 1  is transferred to TV 2  to play. 
         [0162]    After the confirmation between TV 1  and TV 2  through the network messages is made, the transfer of digital media content playback between TV 1  and TV 2  is started until being completed or interrupted. 
         [0163]    The media transport protocol for message negotiation between TV 1  and TV 2  is adopted for transferring the digital media content playback, for example, Real Time Transport Protocol/Real Time Transport Control Protocol (RTP/RTCP), Hyper Text Transport Protocol (HTTP) type Adaptive Streaming (HAS), File Transport Protocol (FTP), a Wireless Fidelity (WiFi) display technology, a Wireless Home Digital Interface (WHDI), Wireless High Definition (WiHD) protocol and the like may be adopted. 
         [0164]    In a transfer process, information such as coding and decoding parameters, a time shift parameter of the played content and the like may be transmitted between TV 1  and TV 2 . 
         [0165]    When the playing or transmission of the digital media content on TV 1  is completed, TV 1  can send a message to TV 2  to notify TV 2  that playing is completed, and removes the network connection. 
         [0166]    In the first embodiment, TV 1 , as the first equipment, identifies the gesture directed to TV 1  and sends a multicast request message (the first message) for playback transfer, and then TV 2 , as the second equipment, identifies the gesture directed to TV 2  itself, and sends the second message to TV 1 . Furthermore, the gesture may be only directed to the first equipment TV 1 , and TV 1  sends the first message to trigger playback transfer negotiation after identifying the gesture directed to TV 1  itself. 
         [0167]      FIG. 5  is a principle diagram of a method for transferring digital media content playback according to a second embodiment of the present disclosure, and as shown in  FIG. 5 , the method includes the following steps. 
         [0168]    Step  501  includes that first equipment detects a body movement of a user for transferring out digital media content playback, and sends the second equipment a first message for notifying the second equipment to get ready to transfer the digital media content playback to second equipment. 
         [0169]    Step  501  is specifically implemented as follows: the first equipment, after detecting the body movement of the user for transferring out the digital media content playback, obtains first positional relationship information between the first equipment and the user, encapsulates the first positional relationship information into the first message, and sends the first message to the second equipment for the second equipment to determine the first equipment for receiving its second message according to the first positional relationship information in the first message. 
         [0170]    Step  502  includes that the first equipment receives the second message responsive to the first message from the second equipment, and transfers the digital media content playback to the second equipment to play according to the second message. 
         [0171]    Step  502  is specifically implemented as follows: the first equipment receives one or more second messages from one or more second equipment, extracts one or more pieces of second positional relationship information from the one or more second messages, and determines the second equipment for transferring its digital media content playback according to the one or more pieces of second positional relationship information. 
         [0172]    Preferably, the first/second positional relationship information is angle information formed by an arm, a hand and the first/second equipment, or the first/second positional relationship information is distance information between the hand or arm and the first/second equipment. 
         [0173]    Preferably, the first equipment detects the body movement by virtue of its photographic part, and the body movement is a gesture including grabbing/pinching and taking-back. 
         [0174]      FIG. 6  is a schematic diagram of an application scenario of transferring digital media content playback according to a second embodiment of the present disclosure. Each equipment and their relationships are shown in  FIG. 6 , and a system includes two equipment which are both TVs: TV 1  and TV 2 . 
         [0175]    There is a photographic part (such as a camera) on TV 1  which serves as the first equipment, and a user may make the grabbing movement and the like with a hand in front of the camera. In the embodiment, the movements which can be identified by TV 1  are as follows respectively: 
         [0176]    1) grabbing: the user makes a grabbing movement or a pinching movement with a hand at the camera; and 
         [0177]    2) taking-back: the user makes a taking-back movement with a palm and an arm at the camera: the arm is straightened at the camera, and then the forearm is bent back towards a midline direction of a body of the user. 
         [0178]    TV 1  sends TV 2  the first message for notifying TV 2  to get ready for reception after receiving or identifying the body movement representing that the digital media content playback is to be transferred out of the first equipment, and notifies TV 2  of its own digital media content playing capability to facilitate the transfer of the digital media content playback. 
         [0179]      FIG. 7  is schematic diagram illustrating a flowchart of network messages in a control method according to a second embodiment of the present disclosure. As shown in  FIG. 7 , there are two first equipment TV 1  and TV 3  and one equipment TV 2  in the embodiment, and the flow includes the following steps: 
         [0180]    step  701 : the user demonstrates a first movement on TV 1 , and both TV 1  and TV 3  identify the first movement, and determine a transfer intention of the user, namely identifying that current video playback is to be transferred to another equipment to play; 
         [0181]    step  702 : TV 1  and TV 3  broadcast first messages READY PLEASE for notifying the other equipment to get ready for identification and reception respectively after identifying the body movement of the user for transferring out the digital media content playback, and notify other equipment of their own digital media content playing capabilities; 
         [0182]    step  703 : TV 2  may send a second message PAIRED OK or PAIR FAILURED to only one TV 1 . That is, TV 2  determines and selects the most accurate first equipment according to gesture position information given by the first equipment in the received first messages after receiving the first messages sent by multiple first equipment like TV 1  and TV 3 , and responds to the first equipment with the second message PAIRED OK. In the embodiment, TV 2  confirms that TV 2  has been ready to receive the digital media content playback to TV 1 , namely sending the second message PAIRED OK to TV 1 ; 
         [0183]    Step  704 : TV 1  gives a response to the message PAIRED OK with PAIRED CONFIRM, that is, TV 1  transfers the digital media content playback to TV 2  to play; and 
         [0184]    Step  705 : the current digital media content playback of TV 1  is transferred to TV 2  to play. 
         [0185]    After the confirmation between TV 1  and TV 2  through the network messages, the transfer of digital media content playback between TV 1  and TV 2  is started until being completed or interrupted. 
         [0186]    The present disclosure further provides a third embodiment: under the condition that there is first equipment (TV 1 ) that is playing a digital media content, the user makes a gesture to multiple second equipment (TV 2  and the like), and the second equipment such as TV 2  triggers a network message (the second message) PAIRED OK after identifying the gesture, the message being sent in a multicast/broadcast manner, a content contained in the message being as mentioned in the first embodiment; and the first equipment TV playing the digital media content, after receiving the message PAIRED OK, determines and selects the target second equipment (for example, TV 2  is selected) by virtue of the determination manner in the abovementioned manners, that is, according to the positional relationship information, and TV 1  sends a response message PAIRED CONFIRM to TV 2 , the message containing negotiation information for received PAIRED OK. After a one-to-one connection is established by TV 1  and TV 2 , subsequent playback transfer control is similar to that in the abovementioned embodiments. Further description is given below with reference to  FIG. 8  to  FIG. 10 . 
         [0187]      FIG. 8  is a principle diagram of a method for transferring digital media content playback according to a third embodiment of the present disclosure, and as shown in  FIG. 8 , the method includes the following steps: 
         [0188]    step  801 : second equipment detects a body movement of a user for transferring the digital media content playback to the second equipment, and sends a second message for showing its digital media content playing capability to first equipment; 
         [0189]    step  801  is specifically implemented as follows: the second equipment, after detecting the body movement of the user for transferring the digital media content playback to the second equipment, obtains second positional relationship information between the second equipment and the user, encapsulates the second positional relationship information into the second message, and sends the second message to the first equipment, so that the first equipment determines the second equipment for transferring its digital media content playback according to the second positional relationship information in the second message after receiving the second messages from one or more second equipment, and sends a third message to the determined second equipment, wherein the second equipment detects the body movement by virtue of its photographic part, and the body movement is a gesture including throwing/pointing/finger spreading; and 
         [0190]    step  802 : the second equipment receives a third message responsive to the second message from the first equipment, and transfers the digital media content playback of the first equipment to the second equipment to play according to the third message; 
         [0191]    step  802  is specifically implemented as follows: the second equipment, after receiving the third message, transfers the digital media content playback to the second equipment to play when the third message is a message of transferring the digital media content playback. 
         [0192]      FIG. 9  is a schematic diagram of an application scenario of transferring digital media content playback according to a third embodiment of the present disclosure. Each equipment and their relationships are shown in  FIG. 9 , and there are two equipment which are both TVs: TV 1  and TV 2 . 
         [0193]    TV 2 , as second equipment, has a photographic part (such as a camera). The user may make a throwing, releasing or pointing movement and the like in front of the camera of TV 2 . In the embodiment, the movements which can be identified by TV 2  are as follows respectively: 
         [0194]    1) throwing: the user makes a throwing movement with a hand at the camera of TV 2 ; 
         [0195]    2) releasing: the user keeps a grabbing or pinching movement in the first group, and then makes a releasing movement with a hand at the camera of TV 2 ; 
         [0196]    3) pointing: the user makes a pointing movement at the camera of TV 2 ; and 
         [0197]    4) spreading; if TV 2  has a touch screen, five fingers are gathered, and then the fingers are spread on the touch screen. 
         [0198]    At first, TV 2  sends a second message to TV 1  to notify TV 1  that TV 2  has been ready to receive the digital media content playback after receiving or identifying the body movement for transferring the digital media content playback to TV 2  to play, the second message including the second positional relationship information (such as the gesture position information) between TV 2  and the user. Then, TV 1  confirms to transfer the digital media content playback to TV 2  to finish transferring the playback. 
         [0199]    Here, the gesture position information may be an angle parameter between the gesture and the equipment, and may also be a distance parameter between the gesture and the equipment. Therefore, when there exist multiple first equipment or multiple second equipment, local equipment can determine the optimal opposite equipment according to the gesture position information of the opposite equipment and respond to the message. 
         [0200]      FIG. 10  is a flowchart of network messages in a control method according to a third embodiment of the present disclosure. As shown in  FIG. 10 , the first equipment is TV 1 , and there are two second equipment: TV 2  and Audio System respectively. In the embodiment, the digital media content is played on TV 1 , the user controls the display media content playback to be transferred from TV 1  to TV 2 , and for the user, scenarios and experiences are as follows: when the throwing movement is made to the camera of TV 2 , the digital media content originally played on TV 1  is played on TV 2 , and the user can directly watch the video content played on TV 2 . The flow includes the following steps. 
         [0201]    Step  1001  includes that the second equipment TV 2  and Audio System identify a second movement, and identify that the digital media content playback is to be transferred to the second equipment to play. 
         [0202]    Step  1002  includes that after the second equipment TV 2  and Audio System identify the body movement of the user for transferring the digital media content playback to the second equipment, TV 2  and Audio System send to the first equipment second messages PAIRED OK to confirm that TV 2  and Audio System have been ready to receive the digital media content playback. 
         [0203]    In Step  1002 , there are two kinds of second messages: the first is PAIRED OK, representing that the equipment can receive the digital media content playback; and the other is PAIR FAILED, representing that the equipment cannot receive the transferred digital media content playback although identifying the movement. In the embodiment, TV 2  and Audio System send PAIRED OK to TV 1 . In the embodiment, TV 2  and Audio System send PAIRED OK to TV 1 , the second message including the gesture position information identified by the second equipment. 
         [0204]    Step  1003  includes that TV 1  gives a response PAIRED CONFIRM or PAIR REFUSED to the message PAIRED OK. 
         [0205]    TV 1  sends the third message PAIRED CONFIRM or PAIR REFUSED to TV 2  or Audio System. In the embodiment, TV 1  sends PAIRED CONFIRM to TV 2 , and sends PAIR REFUSED to Audio System, namely TV 1  selects to transfer the digital media content to TV 2  to play. 
         [0206]    TV 1  may determine the optimal second equipment according to the gesture position information identified by the second equipment when receiving PAIRED OK from multiple second equipment such as TV 2  and Audio System in  FIG. 10 . Of course, TV 1  may also provide an operating interface for the user to select the target equipment, for example, options are listed on the screen, the user selects the equipment, and then the subsequent flow is continued. 
         [0207]    Step  1004  includes that the current digital media content playback on TV 1  is transferred to TV 2  to play. 
         [0208]    After the confirmation between TV 1  and TV 2  is made through the network messages, the transfer of digital media content playback between TV 1  and TV 2  is started until being completed or interrupted. 
         [0209]    As a fourth embodiment, gestures may be simultaneously made for the first equipment and the second equipment, the two kinds of equipment (which may be not only one equipment) simultaneously identify the gestures, and trigger playback transfer negotiation. Such a network message flow is similar to that in the first embodiment, and will not be repeated here. 
         [0210]    From the aspect of data transmission, digital media content playback transfer is, for example, as follows: 
         [0211]    (1) TV 1  sends file/data to TV 2  at a time, or 
         [0212]    (2) TV 1  sends file/data to TV 2  in form of stream, or 
         [0213]    (3) TV 1  notifies TV 2  of an address of a content source on another equipment, and TV 2  downloads file/data from the address of the content source, or 
         [0214]    (4) TV 1  notifies TV 2  of an address of a content source on another equipment, and TV 2  receives a media stream from the content source, and the like. 
         [0215]    In the embodiment, TV 1  serves as the first equipment, the first equipment is not limited to be equipment like TV 1  in the present disclosure, a mobile phone, other player with a touch screen (remote controller), even a computer and the like may be adopted as the first equipment, and the triggering function in the abovementioned flows may also be realized by virtue of a keyboard and a mouse on the computer. 
         [0216]    In the embodiment, TV 2  and Audio System serve as the second equipment, the second equipment is not limited to be equipment like a TV in the present disclosure; a mobile phone, a set-top box, projector, a computer and the like with cameras and various capabilities described in the embodiments can be adopted as the second equipment. 
         [0217]    In the embodiment, contents can be transmitted and shared between different equipment in a family, for example, a mobile phone transmits an image to a TV, and simultaneously transmits sound to audio equipment, and in a place like an exhibition hall with multiple TVs, the playback of multiple contents and the like are transferred to different TVs at the same physical position. 
         [0218]    The above flows are not limited to be implemented only by the embodiments, and are also not intended to limit the methods executed by specific flows, the present disclosure may further be implemented by virtue of similar manners, for example, names representing the modules and types of various messages, and differences only exist between naming forms, specific message contents and the like. 
         [0219]    The embodiments are network-related, and can be applied to an IP network supported by a communication network such as an IEEE 802.3-based network, an IEEE 802.11b/g/n-based network, a POWERLINE network, a CABLE network, a Public Switched Telephone Network (PSTN), a 3rd Generation Partnership Project (3GPP) network and a 3GPP2 network, an operation system of each apparatus can be applied to a UNIX operation system, a WINDOWS operation system, an ANDROID operation system and an Iphone Operation System (IOS), and a consumer interface can be applied to a JAVA language interface and the like.
