step 101: the method comprises the steps that a main node device in a local area network acquires multimedia resource information of one or more slave node devices in the local area network, and a multimedia resource list is generated according to the acquired multimedia resource information of the one or more slave node devices and the local multimedia resource information of the main node device;
specifically, the lan may be a lan established by a personal lan technology, for example, a multipoint connection (multipoint connectivity) technology provided by the ios7 system, a wifi direct function provided by the Android system, a bluetooth low energy (bluetooth) technology, and the like.
Specifically, the master node device and the slave node device are both node devices having multimedia resource storage, identification and playing capabilities, and in practical application, the node devices may be mobile terminals such as mobile phones, tablet computers and portable computers.
In step 101, after acquiring multimedia resource information of one or more slave node devices in a local area network, a master node device in the local area network generates a multimedia resource list according to the acquired multimedia resource information. The multimedia resource list lists multimedia resource information, such as multimedia resource names, on all node devices in the local area network, and can know which multimedia resources are owned in the local area network through the list.
In this step, the master node device may further generate multimedia resource information in a local area network according to the acquired multimedia resource information, where the multimedia resource information in the local area network includes: the local multimedia resource information of the main node equipment and the multimedia resource information of the slave node equipment. Specifically, the master node device generates multimedia resource information in the local area network by the following method: combining the multimedia resource information of one or more slave node devices in the local area network with the local multimedia resource of the master node device to generate total multimedia resource information (namely, the multimedia resource information in the local area network) in the local area network; specifically, the sum of the multimedia resource information of one or more slave node devices in the local area network and the multimedia resource information local to the master node device constitutes the multimedia resource information in the entire local area network. In a specific implementation, the multimedia resource information of the one or more slave node devices and the multimedia resource information local to the master node device may be written into a data table, where the data table is used to carry the multimedia resource information in the local area network.
In this step, the master node device in the local area network may obtain the multimedia resource information of one or more slave node devices in the local area network in a plurality of ways, for example: the master node equipment sends a multimedia resource information acquisition request to the slave node equipment, and then the slave node equipment returns the multimedia resource information of the slave node equipment to the master node equipment in response to the request; or, the slave node device reports the multimedia resource information of itself to the master node device actively.
The multimedia resource information of the one or more slave node devices, or the multimedia resource information local to the master node device, or the multimedia resource information in the local area network at least includes a name of the multimedia resource, and may further include a storage location of the multimedia resource. Specifically, the name of the multimedia resource is used to identify the content of the multimedia resource, and the storage location of the multimedia resource is specifically the storage address of the multimedia resource.

The multimedia resource may be at least one of the following types of resources: video resources, audio resources, and text resources.
Thus, in step 101, the master node device may obtain multimedia resource information on all available node devices in the local area network (including the master node device itself and one or more slave node devices), so as to manage all multimedia resources in the local area network.
Step 102: and the master node device informs one or more slave node devices in the local area network of the multimedia resource list so that the one or more slave node devices in the local area network acquire the multimedia resources in the local area network.
In step 102, the master node device notifies the generated multimedia resource list to one or more slave node devices in the local area network, so that the slave node devices in the local area network can also acquire multimedia resource information on all the node devices in the local area network, as with the master node device. Furthermore, both the master node device and the slave node device in the local area network can select the required multimedia resource according to the self requirement and acquire the corresponding resource.
In summary, the embodiment of the invention can realize multimedia resource sharing among a plurality of node devices in the local area network, thereby not only meeting the multimedia resource playing requirement of the user to the maximum extent, but also saving the user flow, and greatly improving the user experience; in addition, the multimedia resource sharing method provided by the invention has the advantages of simple and convenient implementation mode and very high operability.
Example two
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a multimedia resource sharing method according to the present invention is shown, which may specifically include:
step 201: the method comprises the steps that a main node device in a local area network acquires multimedia resource information of one or more slave node devices in the local area network, and a multimedia resource list is generated according to the acquired multimedia resource information of the one or more slave node devices and the local multimedia resource information of the main node device, wherein the multimedia resource information at least comprises names of multimedia resources.
In this step, the lan may be a lan established by a personal lan technology, for example, a multipeerconnection technology provided by the ios7 system, a wifi direct function provided by the Android system, a bluetooth lowenergy technology, and the like.
In this step, the multimedia asset information may further include a storage location of the multimedia asset.
Specifically, the name of the multimedia resource is used for identifying the content of the multimedia resource; the storage location of the multimedia resource is specifically a storage address of the multimedia resource. In the above scheme, the multimedia resource information may further include information such as size and format of the multimedia resource.
Specifically, the master node device and the slave node device are both node devices having multimedia resource storage, identification and playing capabilities, and in practical application, the node devices may be mobile terminals such as mobile phones, tablet computers and portable computers.
Usually, only one node device in the local area network is a master node device at the same time, and other node devices are all slave node devices. In practical applications, the node device that creates the local area network may be set as a master node device, or the master node device may be determined by some preset rule, for example, one of all the node devices is randomly selected as the master node device.
The device that has been determined to be the master node device may choose to exit or leave the local area network, or actively give up the identity of the master node device, and at this time, the master node device may be determined in various ways, for example, the master node device randomly designates one node device in the local area network as the master node device, or designates the node device with the highest score in the local area network as the master node device, or designates the node device with the longest network time in the local area network as the master node device. Specifically, the network time refers to a continuous residence time of the node device in the local area network, and in actual implementation, the longest time for the node device to maintain the network connection state after joining the local area network may be taken as the network time.
Specifically, the node device with the highest score in the local area network may be determined by:
and comprehensively comparing the on-line time, the uploading times, the downloading times, the resource usage amount, the uploading and downloading activeness, the contribution degree and the like of all the node equipment. Specifically, the longer the network time is, the more the uploading times and the downloading times are, the higher the uploading and downloading activity and contribution degrees are, the higher the score is, and finally, the node device with the highest score is the node device with the highest score in the local area network.
In step 201, after acquiring multimedia resource information of one or more slave node devices in a local area network, a master node device in the local area network generates a multimedia resource list according to the acquired multimedia resource information. The multimedia resource list lists multimedia resource information, such as multimedia resource names, on all node devices in the local area network, and can know which multimedia resources are owned in the local area network through the list.
In this step, the master node device may further generate multimedia resource information in a local area network according to the acquired multimedia resource information, where the multimedia resource information in the local area network includes: the local multimedia resource information of the main node equipment and the multimedia resource information of the slave node equipment. Specifically, the master node device generates multimedia resource information in the local area network by the following method: the multimedia resource information of one or more slave node devices in the local area network is combined with the local multimedia resource to generate the total multimedia resource information in the local area network (i.e. the multimedia resource information in the local area network).
The master node device in the local area network may obtain the multimedia resource information of one or more slave node devices in the area network in various ways, for example: the master node equipment sends a multimedia resource information acquisition request to the slave node equipment, and then the slave node equipment returns the multimedia resource information of the slave node equipment to the master node equipment in response to the request; or, the slave node device reports the multimedia resource information of itself to the master node device actively.
Therefore, through step 201, the master node device may obtain multimedia resource information on all available node devices in the local area network (including the master node device itself and one or more slave node devices), so as to manage all multimedia resources in the local area network, and achieve the purpose of managing resource obtaining requests of all node devices in the local area network by managing multimedia resources. Therefore, multimedia resource sharing among different node devices in the local area network can be realized by managing resource acquisition requests of all the node devices in the local area network.
Step 202: the master node device informs one or more slave node devices in a local area network of the multimedia resource list;
in step 202, the master node device notifies the generated multimedia resource list to one or more slave node devices in the local area network, so that the slave node devices in the local area network can also know which multimedia resources are owned by all the node devices in the local area network, as with the master node device. Furthermore, both the master node device and the slave node device in the local area network can select the required multimedia resource according to the self requirement and acquire the corresponding resource.
Step 203: the method comprises the steps that a main node device receives multimedia resource acquisition requests of one or more slave node devices, and the multimedia resource acquisition requests are processed, so that the one or more slave node devices in the local area network can acquire multimedia resources in the local area network.
Specifically, when the master node device receives a multimedia resource acquisition request from the slave node device, the master node device processes the multimedia resource acquisition request in the following manner:
the master node equipment determines the storage position of the multimedia resource requested to be acquired by the slave node equipment;
when the determined storage position is one, determining the transmission state of the multimedia resource on the storage position, and if the transmission state is idle, sending the information of the storage position to slave node equipment; correspondingly, if the transmission state of the multimedia resource on the storage position is busy, a response message is returned to the slave node equipment to indicate that no multimedia resource is available;
when the determined storage positions are multiple, determining the transmission states of the multimedia resources on the multiple storage positions, and sending the information of the storage positions with the transmission states of the multimedia resources being idle on the multiple storage positions to the slave node device, that is, the master node device only sends the information of the storage positions with the transmission states of the multimedia resources being idle in the determined storage positions to the slave node device, so that the efficiency of obtaining the multimedia resources from the slave node device is improved, and the waste of time for obtaining the required multimedia resources from the positions with the transmission states being busy in the slave node device is avoided; correspondingly, if the transmission states of the multimedia resources on the plurality of storage positions are all busy, a response message is returned to the slave node equipment to indicate that no multimedia resources are available.
In the above solution, before the master node device determines the transmission status of the multimedia resource at the corresponding storage location, the method further includes the following steps: the method comprises the steps that a main node device obtains the transmission state of multimedia resources in one or more slave node devices in a local area network; the transmission state can be obtained by the slave node device actively or on request sending the transmission state of the multimedia resource to the master node device.
In another optional embodiment of the present invention, the method further comprises: the method comprises the steps that a main node device obtains device information of slave node devices in a local area network, a device list in the local area network is generated according to the device information of the main node device and the obtained device information, and when one or more slave node devices in the local area network are detected to leave, the device list in the local area network and multimedia resource information in the local area network are updated.

Application example
Fig. 4 is an exemplary application scenario according to the embodiment of the present invention, and as shown in fig. 4, the scenario includes a plurality of node devices: node device C1, node device C2, node device C3, and node device C4. The following describes the multimedia resource sharing method in detail by taking video resource sharing as an example.
The node devices C1, C2, C3, and C4 may all obtain online video resources through the network, when the network is disconnected, C1 first detects a local area network existing around, when the detection fails, C1 creates a local area network by using the personal area network technology, as a node device for creating the local area network, and C1 becomes a master node device. Then, the local area network is internally managed through the following scheme:
1. network management maintenance
1.1 node device registration
After the C1 creates a lan, the node devices C2, C3 and C4 all find the lan created by C1 through searching and join the lan; at this time, the master node device C1 may broadcast its own identity information periodically through the local area network, and at this time, other node devices that receive the broadcast message may all determine the master node device identity of C1, and the slave node device identity of itself may also determine; thereafter, the plurality of slave node devices C2, C3, and C4 are registered with the master node device C1, respectively.
1.2 Slave node device information reporting
After the slave node devices C2, C3, and C4 complete registration with the master node device C1, report their own device information and multimedia resource information to the master node device C1.
For example, as shown in fig. 4, after C4 registers with C1, in addition to informing own device information, it also informs the information of locally stored a1 and a2 resources; correspondingly, the C2 informs the C1 of the own equipment information and the information of the locally stored A2 resource; wherein A1 and A2 together form an A resource, that is, the A resource is composed of two parts, A1 and A2. C3 informs C1 of its own device information and locally stored information of B resources, and C4 informs C1 of its own device information and locally stored information of C resources. Thus, C1 knows the distribution of all video assets within the local area network.
Further, in the process of acquiring resources in the local area network, each slave node device reports the transmission state of the local resources to the master node device, where the transmission state may be busy or idle, busy means that the resources are occupied, and idle means that the resources are unoccupied.
1.3 information integration in LANs
The master node device C1 determines a device list existing in the local area network according to the device information reported by the slave node device, and determines multimedia resource information in the local area network according to the multimedia resource information reported by the slave node device, including names and storage locations of multimedia resources stored in all the node devices in the local area network; the master node device may generate a multimedia resource list according to the multimedia resource information in the local area network, where the multimedia resource list lists all video resources in the local area network.
1.4 Scoring mechanism
After joining the network, the slave node device will also feed back its own activity information to the master node device through heartbeat at regular or irregular time, the activity information includes: the master node equipment can also collect self activity information at regular time according to network time, uploading times, downloading times, resource usage, uploading and downloading activeness and contribution degree and the like, the activity information can be used as an equipment grading standard, node equipment with higher comprehensive grading is stable node equipment in the local area network, and can have downloading priority and also be used as a candidate of next master node equipment.
1.5 guard node device
In the local area network, one or more guard node devices are arranged in addition to the key node device, i.e., the master node device. The guard node device is responsible for detecting whether the main node device is still inside the local area network. Therefore, the daemon node device itself also needs to have higher stability, and therefore, the daemon node device also consists of N nodes with the highest score, where N is a positive integer greater than or equal to 1, and the value of N is 20% of the total number of nodes at the maximum, for example, if 10 devices are on the network, 2 daemon nodes are needed.
1.6 Master node device replacement
The main node device in the local area network may leave the local area network under many circumstances, for example, the main node device leaves the range of the local area network, and at this time, the guard node device may not detect the main node device, or the performance of the main node device may be degraded, and actively quit the local area network, or automatically retire the main node device after the main node device reaches a preset service duration, in order to avoid a trouble of other node device users caused by excessive contribution of the main node device. After the device leaves or is retired, the daemon node device with the highest score can be automatically upgraded to the main node device, and the newly determined main node device broadcasts the information of the daemon node device to all the node devices of the local area network.
2. Resource sharing control
2.1 multimedia resource acquisition request
The master node equipment issues the generated multimedia resource list to each slave node equipment in the local area network, so that each slave node equipment can know all video resources in the local area network and request to acquire resources in the multimedia resource list according to needs;
2.2 multimedia resource acquisition request processing
After receiving the multimedia resource acquisition request sent by the slave node device, the master node may process the multimedia resource acquisition request in the following manner:
the master node equipment determines the storage position of the multimedia resource requested to be acquired by the slave node equipment;
when the determined storage position is one, determining the transmission state of the multimedia resource on the storage position, and if the transmission state is idle, sending the information of the storage position to slave node equipment; correspondingly, if the transmission state of the multimedia resource on the storage position is busy, a response message is returned to the slave node equipment to indicate that no multimedia resource is available;
when the determined storage positions are multiple, determining the transmission states of the multimedia resources on the multiple storage positions, and sending the information of the storage positions of the multimedia resources with idle transmission states on the multiple storage positions to the slave node equipment; correspondingly, if the transmission states of the multimedia resources on the plurality of storage positions are all busy, a response message is returned to the slave node equipment to indicate that no multimedia resources are available.
In another optional implementation manner of the present invention, after receiving a multimedia resource acquisition request sent by a slave node device, a master node may also directly determine a storage location of a multimedia resource requested to be acquired by the slave node device; and directly transmits the determined storage location of the multimedia resource to the slave node device.
2.3 multimedia resource acquisition
After receiving the multimedia resource storage location information returned by the master node device, the slave node device may initiate a resource acquisition request to a target slave node device according to the storage location information, if the resource at the corresponding location is occupied, the slave node device requesting to acquire the resource initiates a resource acquisition request to other locations, and if the resources at all the locations are occupied, the slave node device requesting to acquire the resource may wait for a corresponding time and then alternately transmit the resource acquisition request to each target slave node device again; or inquiring the use condition of the corresponding resource on each destination slave node device at regular time, and acquiring the resource when the corresponding resource is idle.
It should be noted that, in order to control the battery consumption of the node device, the above scheme may perform upload control on the resource, for example, each device cannot upload a multimedia resource to two or more node devices at the same time.
For the video resources to be acquired which are composed of two or more files with different resolutions, the two or more video resources can be spliced or each video file can be transcoded according to the lowest resolution of two or more video clips, so that the viewing experience is enhanced.
In the process of acquiring the multimedia resource, when a plurality of slave node devices simultaneously request the same multimedia resource, in order to encourage the node device with high device score, a corresponding mechanism can be set, namely, the slave node device with high score can preferentially obtain the multimedia resource.
Taking fig. 4 as an example, the node device C2 requests the user to select to play the B video resource, and the B resource is stored in the node device C3, and it is assumed that at the same time, the master node device C1 also just requests to play the B resource, but due to the upload control, the node device C3 can only transmit to one node device, and due to the high score of the master node device C1, the node device C1 can preferentially acquire the B resource and play it, and the node device C2 can only wait a little.
For the above application example, it should be noted that, in the local area network, each node device (including the master node device and the slave node device) may obtain the multimedia resource between each two node devices. For the master node device C1, it can be considered that there are two services on C1, one is the master control service and the other is the play service.
When the C1 needs to play the video, the play service on the C1 accesses the local master control service to request the corresponding video resource, so that the master control service controls the resource requested by the play service; when the resource requested by the C1 is a local resource, the C1 directly reads the locally stored resource; when the resource requested by C1 is a video resource on other slave node devices; then, after the C1 obtains the storage location information of the corresponding resource, it may request the slave node device storing the corresponding resource to obtain the corresponding resource, and then the corresponding slave node device determines whether to transmit the corresponding resource to the master node device, that is, when the requested video resource is idle, the corresponding video resource is transmitted to the master node device, and when the requested video resource is busy, a response message is returned to the master node device to notify that the master node device is busy. The master node device may wait for a period of time before initiating a request to the corresponding slave node device again.
It can be seen that the difference between the resource acquisition request initiated by the master node device and the resource acquisition request initiated by the slave node device is only that the resource acquisition request initiated by the master node device is processed locally, and the resource acquisition request of the slave node device is processed by the master control node after accessing the master control node through the local area network.
