## Background
TECHNICAL FIELD
The present disclosure relates to the field of computer techniques, and in particular to a method, device and system for switching back transferred-for-play digital media content.
BACKGROUND
With the development of digital multimedia and networks, entertainment experiences in daily life are enriched. Existing techniques enable people at home to enjoy high definition TV programs from a digital disk, cable TV or the Internet and the like. In addition, users are enabled to experience stereo, 5.1 acoustic channel, 7.1 acoustic channel or even more realistic sound effect; people can also implement these experiences using a tablet electronic device (pad) or a mobile phone; moreover, playing of digital content can be transferred between equipments through a network, and the playing in an equipment can be controlled through a remote controller or through a gesture, such as control of switching to a previous and a next channel.
In the related art, for controlling multiple equipments, generally each equipment has a respective remote controller to perform control, but these remote controllers are not universal, and most of these controllers, such as a traditional TV set or sound box, cannot be networked. There may be some network enabled controllers, for example, an equipment (e.g., a mobile phone, a pad) having computing and networking capabilities can be loaded with software supporting intercommunication protocols to control another equipment. Gesture control is currently a relatively new control manner in which a camera on an equipment monitors gesture actions and then analyzes and identifies them, finally the gesture actions are converted to control of the equipment.
With the development of techniques, there are increasing demands for sharing and transferring of content being played between multiple equipments, and the above control method is apparently not so convenient; people may need to select one remote controller corresponding to a specific equipment from a pile of remote controllers and change remote controllers from time to time to control different equipments, or the equipment can be controlled through operations on a pad or a mobile phone by people familiar with basic operations on computers, or a single equipment is controlled by simple gestures. People prefer to use an easier and more natural operation way to control shared playing or transferred playing of content.
Some products in the related art enable people to transfer digital media content being played on an equipment to another equipment, for example, an existing Universal Plug and Play (UPnP) protocol enables transferring of video played on a mobile phone to a TV. Some manufacturers of TVs, mobile phones, players and home storages have also produced similar products.
When such a play transferring functionality is used, it is desired in certain cases that transferred play can be transferred back, for example, content transferred and watched on a TV is transferred to its original mobile phone so as to be carried out for play, or after being transferred back to the mobile phone, the content is transferred to another equipment such as a computer so as to be watched thereon. People can, of course, implement these functions with a menu of a computer application on a TV, but it is desired that the operation can be easier and more natural.
It is desired that content, after being subjected to inter-equipment transfer and collaborative play, can be switched back to its original equipment through an easier and more natural operation, so as to provide users with more relaxed and enjoyed entertainment, and users also require that they can understand and get started more easily when new functions of an equipment are introduced.

Preferably, after step 102, the following processing may be included: the second equipment stops playing the digital media content, and disconnects from a content source corresponding to the digital media content.
Step 102 specifically includes: 1. the second equipment identifies the user action with an identification device; 2. it is determined whether the identified user action is matched with preset action determination data, if yes, the playing of digital media content is switched back to the first equipment.
Specifically, the user action includes a gesture action, a eyeball action and a body gesture, wherein the gesture action includes a backward bending of an arm after a grasp, a backward bending of an arm after the arm and corresponding palm are straightened to face the identification device, and a predetermined number of swings of an arm and corresponding palm towards the body of a user after being raised to face the identification device.
In step 102, the above method may further include: after the second equipment notifies, according to the information of the first equipment, the first equipment to take over playing of the digital media content, the second equipment receives a response message from the first equipment, and acquires information carried in the response message regarding whether switching back of playing of the digital media content is allowed. If determining according to the response message that the first equipment allows the switch back, the second equipment stops playing the digital media content, and disconnects from the content source corresponding to the digital media content.
In an embodiment of the disclosure, after step 102 is implemented, the first equipment may confirm whether to play digital media content switched back to the first equipment, and the confirmation operation may be a menu option displayed by the first equipment or a reception gesture.
The above technical solutions according to embodiments of the disclosure will be elaborated below with reference to the accompanying drawings.
FIG. 2 is a schematic diagram showing control of equipments according to an embodiment of the disclosure, as shown in FIG. 2, there are two equipments: a pad and a TV; in the example, the pad serves as a first equipment playing digital media content that may include a video file stored locally, a video stream from an IP network, a local audio, an audio stream from an IP network or a desktop of an operation system.
In the embodiment, the pad has an interface for interacting with users, which enables a user to input determination information for a process, e.g., approval or rejection to switching back transferred-for-play digital media content.
In addition, the pad has a network interface that supports IEEE 802.11b/g/n and IEEE 802.3, thus being capable of being connected to an IP network. Modules within the pad may further have a network service capability that enables the pad to be found by and connected to other equipments, and to transmit/receive messages to/from other equipments.
In an example, the TV is a second equipment and has one camera. Users can, in front of the camera, make actions such as throwing, releasing or pointing with a hand. The TV has a capability of identifying that a transferred digital media content being played is to be transferred back, that is, the TV can acquire, through a camera, a motion image so that it can identify, according to a predefined rule, that transferred digital media content that is being played is required to be transferred back to the pad for play, namely knowing that the digital media content is about to be transferred, and such a identification is implemented in the following context: a throwing action, a releasing action, a pointing action or a splay of a hand on a touch screen (if the TV has a touch screen). In addition, the TV has a network interface that supports IEEE 802.11b/g/n and IEEE 802.3, thus being capable of being connected to an IP network. Modules within the TV may further have a network service capability that enables the pad to be found by and connected to other equipments, and to transmit/receive messages to/from the pad. The pad and the TV are connected with each other through a network.
Preferably, in the example, actions that can be identified by the TV include:
1. a backward grasp, namely a backward bending of an arm after a grasp;
2. a backward wave, namely a backward bending of an arm after the arm and corresponding palm are straightened to face the camera of the TV; and
3. a swing, namely two or more swings of an arm and corresponding palm towards the body of a user after being raised to face the camera of the TV.
On the TV, the identification of gesture actions can be implemented using the histogram method or the Markov model method. Firstly, gesture actions of a user should fall within a capturing scope of the camera so that the camera can generate a gesture video transmitted to an identification module, then the identification module, through analyzing color, outline, structured light of gesture images in the video, identifies position of the hand, detects and splits gesture objects, extracts gesture features and tracks corresponding gesture motion; then the direction of fingers and a motion direction sequence is processed, finally the gesture action is completely identified, then the operation intention of the user's action can be determined by methods such as comparing with a space of predefined gesture actions.
It should be noted that in the embodiment of the disclosure, an eyeball action and a body gesture can also be used in addition to the aforementioned gesture actions. In addition, the network service capability of the pad and the TV includes a capability enabling the pad and the TV to communicate with each other through a network.
FIG. 3 is a schematic diagram showing network message flow of a control method according to an embodiment of the disclosure. Corresponding to devices in FIG. 2, the first equipment is a pad and the second equipment is a TV in FIG. 3. In the example, digital media content is firstly played on the pad, and then an operation performed by a user causes the digital media content to be transferred from the pad to the TV; for the user, a corresponding scenario and experience include: the user, sitting on a sofa in a living room of his/her residence, has transferred digital media content originally played on the pad to the TV for play, and the user is watching video content played on the TV; then the user wants to go to another room and continue watching the video with his/her pad, then a gesture operation is performed to recall the content played on the TV back to the pad so that the content is no longer played by the TV.
In an embodiment as shown in FIG. 3, devices pad and TV are connected through a network and they can communicate with each other. Specifically, the following processing are included:
step 301, digital media content being played on a pad is transferred to a TV for play.
The TV needs to store parameters such as address, port of the original equipment (pad). In addition, after the transferring of the digital media content between the pad and the TV is finished, a session connection established between the pad and the TV is to be managed.
The management of the session connection include an ID of the session, appointment of a heartbeat message, keeping of a maximum session duration and the like.
Step 302, the TV identifies the play switch back action.
The action is namely action 1 in FIG. 3, and action 1 can be any action in the aforementioned first group of actions. The TV can support and at least support one of the actions.
The identification of these actions in the TV is performed in the context and predefined, and the context includes that the TV starts to launch the identification functionality after playing the digital media content transferred from the pad; the identification of the actions is combined with usage of image identification algorithms so that the TV can identify meanings represented by respective actions, i.e., a video being display will be transferred back to its original equipment for play. In step 2, the second equipment identifies that the digital media content will be transferred to its original equipment.
Step 303, after the identification, the TV transmits a broadcast: REQUEST RETURN.
After the TV identifies actions for itself, i.e., after identifying an intention that the digital media content will be transferred to its original equipment for play, if the equipment can receive the digital media content in the broadcast message transmitted from the pad, the TV transmits a request message (i.e., the above REQUEST RETURN message) on the predefined address and port, and the information included in the message is used to request the pad to accept the transfer back of the digital media content for play.
Specifically, the information included in the message includes: name, address, port and timeout of the equipment; wherein the address is an address from which the REQUEST RETURN message is transmitted and an address for subsequent interaction; the timeout represents a valid time of the message, namely a time limit after which the request message will be invalidated (canceled).
In step 303, the second equipment requests the first equipment to get ready for reception of transferred back digital media content.
Step 304, the digital media content is transferred.
Preferably, after receiving the request message from the TV, the pad prompts a user to input confirmation information, the user can select options such as “Yes” or “No” on the pad, which corresponds to action 2 in FIG. 3.
Step 305, the pad transmits a broadcast: RETURN OK.
After confirming that the digital media content can be transferred back for play, the pad transmits, to the TV, a response message, i.e., the RETURN OK message in FIG. 3.
Step 306, the digital media content is transferred back for play.
After the above message interaction and confirmation, the pad takes over playing of the digital media content locally while the TV stops playing, and the PAD and the TV are disconnected. If the digital media content on the pad is received from another content source equipment on the network, the pad can play the digital media content from the another content source in a same way as before the content is transferred to the TV.
In the above embodiment, the first equipment may also transmit a broadcast message, that is, after identifying the intention of transferring back, the first equipment transmits a transfer message; and subsequent processes are similar to above steps; in such embodiments, the first equipment is required to store an address and port of the second equipment to which the content is transferred.
FIG. 4 is a flow chart showing processing logic according to an embodiment of the disclosure. For example, the pad described above may serve as the first equipment and the TV described above may serve as the second equipment.
Step 401, the transfer of play is finished, that is in the above embodiment, the digital media content is transferred from the first equipment to the second equipment for play.
Step 402, the second equipment stores information of the first equipment; the first equipment stores information of the second equipment. Such information can be an address, communication port and the like of the equipment.
Step 403, the second equipment identifies that the content being played is to be switched back to the first equipment. The “identifies” means that the second equipment performs identification through a gesture operation.
Step 404, the second equipment transmits notification information to the first equipment.
Step 405, the first equipment has to confirm whether the switching back is accepted, if yes, the first equipment starts to take over the playing, and the second equipment stops playing and disconnects from a content source. The process ends. If the first equipment confirms that the switching back is not accepted, the first equipment transmits to the second equipment a rejection message, or does not transmit any message until the message is timeout, and the second equipment still continues playing the transferred digital media content.
In the above example, the pad is taken as a first equipment, but in the disclosure the first equipment is not limited to such an equipment as a pad, and mobile phone, other players with a touch screen (remote controller) or even computers can be taken as the first equipment, and the triggering function in the above process may also be implemented by a keyboard or mouse through a computer.
In the above example, the TV is taken as a second equipment, but in the disclosure the second equipment is not limited to such an equipment as a TV, and any equipment configured with a camera and having various capabilities described in the embodiments, such as a mobile phone, a set top box, a projector, a computer and the like, can serve as the second equipment.
The above process is an embodiment to implement the disclosure, but it is not intended to limit the disclosure to the embodiment, and it is not intended to limit the specific method to implement the process; the method can be implemented using similar methods, names of modules and types of various messages are only forms for naming, and indicate that they represent different message contents.
In addition, in the above embodiment, portions related to a network may be applied to IP networks supported by communication networks such as those based on IEEE 802.3, IEEE 802.11b/g/n, POWELINE, CABLE, PSTN, a 3GPP network and a 3GPP2 network; operation systems of various devices may include a UNIX operation system, a WINDOWS operation system, an ANDROID and an IOS operation system; and user interface may include JAVA language interface.
