The present invention will be further described in detail below in conjunction with the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 2 is a flowchart of a home network content processing method according to an embodiment of the present invention, including: Step S101: Establish a home network content directory, and establish a home network content directory in a home information center and each terminal associated with the home information center, The home network content directory is used to record home network content information; Step S102: Synchronize the directory level, perform home network content information synchronization on the home information center and the respective terminals, and update the home information center and the home network content directory inside the respective terminals;

Step S103: Allocating a storage attribute identifier, and assigning, to the home information center and the home network content directory inside each terminal, a storage attribute identifier, which is used to indicate a storage location of the home network content listed in the current home network content directory.

The purpose of the above processing is, first, for all home network content belonging to the home network, such as photos in a camera, videos in a mobile phone, photos in a PAD, or audio/video, etc., in a home information center and a camera, a mobile phone, a PAD, etc. Each of the terminals establishes a list-like directory, and presents information of the home network contents, such as "photos", "videos", "audio", "documents", etc., to classify the home network contents by features.

Secondly, the directory in the home information center and all the terminal devices are synchronized. After all the devices share the synchronization, the contents of the directory structure are identical. That is to say, in the home network, through the synchronization process, the directory information in the home information center and other terminals can be seen on each terminal, even if the content is not stored in the terminal, as long as it is a home information center or other terminal. In the middle, the directory level synchronization can be reflected in the directory of the terminal, and the end user can see the existence of all the home network content by querying the directory.

Finally, in order to distinguish the specific storage location of the content in the directory, all the directories are assigned storage attribute identifiers, so that the user can judge at a glance that the file content is stored in the terminal, the home information center or other terminals, for example, in different colors or different colors. The shape of the legend is identified by the way. You can also assign a simple storage attribute identifier to indicate whether the file content in the directory is stored in the terminal. When stored in the terminal, use the dark color identifier. When not stored in the terminal, use the light color identifier. The advantage is that the end user usually only pays attention to whether the file content exists in the terminal, and only the background storage system management program or the administrator pays attention to the storage attributes of all the contents, so that when the storage is organized, it is known whether a certain file is Repeatedly saved many times, Too redundant, clean it up to free up storage space.

The above step S102 is for the directory level update synchronization of the home network content. In the embodiment of the present invention, the home network content itself can be further divided into three levels: a directory level, an abbreviated level, and a complete level.

As mentioned earlier, the directory level is the basic information of the home network content, such as the file name and attributes, and the abbreviated level is the file name, attribute and abbreviated information, and the complete level is the entire content of the home network content. For example, for a photo in a smartphone, the directory level is "holiday travel", the attribute is its data format, and its name "holiday travel" and photo preview form are displayed at the thumbnail level. The complete level is the completion of this photo. Rendering also means storing photo data locally.

The embodiments of the present invention are described in detail below.

In an embodiment of the present invention, a home network content processing system is used to establish a directory of home network content, and the home information center controls file system management of the whole system by using file attributes of the home network, and each terminal controls file presentation and content by using file attributes. Transfer control, etc. Add a storage attribute item to the file attribute to indicate whether the content is saved in the physical storage medium of the terminal. The storage attribute item definition in the file attribute is shown in Table 1;

The bit is 0, indicating that the file content does not exist on the device; the bit is 1, indicating that the file content is stored in the physical storage medium of the device.

The meaning of each storage attribute bit is uniformly allocated and parsed by the home network content processing system, and the meaning of the analysis result is transmitted to each device for subsequent synchronization processing.

For directory-level synchronization processing, when a terminal generates new content, it synchronizes with the information center as soon as possible according to a certain policy, so that other terminals can quickly learn and share the newly added content, and the information center receives the new directory information generated by the terminal, It is necessary to notify other terminals to update the directory as soon as possible. Therefore, both the terminal and the information center may initiate a directory update synchronization activity. Specific use of the current version of the tube The method is synchronized. The home information center internally records the earliest terminal directory version and the incremental portion generated by each subsequent synchronization of the terminal and the information center. Each terminal internally records the previous directory version and the incremental portion of the version.

There are three cases in which the terminal initiates a synchronization action to the information center:

1. The terminal is powered off to power on, from offline to online; and there is no new content in the terminal.

2. The terminal is powered off to power on, from offline to online; and the terminal has new content.

3. The new content is added when the terminal is online.

In the first case, the terminal exchanges version information with the information center. If the information is the same, the synchronization is completed. If it is different, the information center transmits the directory information after the content is added to the terminal, and the terminal version is updated to the information center version.

In the second case, comparing the version of the terminal with the information center, if the same, the terminal sends the updated directory information to the information center, and then adds 1 to the original version number respectively; if not, the information center will increase the terminal. The content is sent to the terminal, and the terminal sends the added content to the information center. Then, the version number of the terminal and the information center are updated to the original version number of the information center plus one.

In the third case, after the terminal newly adds content, within a set time, such as within 20 minutes, it is still not deleted, the system believes that the information can be shared with other terminals of the home, so the directory synchronization is initiated, and the terminal directly Send the contents of the newly added directory to the information center, and then increase the version number of the information center and the terminal by one.

The timing and operation of initiating directory synchronization by the information center is relatively simple. As soon as any terminal updates the directory information, it broadcasts an update notification to other terminals, and transmits the updated directory content information to other terminals, and other terminals receive the update information. After that, the version numbers of both are increased by 1.

After the directory level synchronization is further performed, the abbreviated content synchronization is further performed, and the home information center and each terminal respectively extract the abbreviated content from the locally stored home network content; for the extracted abbreviated content, the home information center and each terminal are performed. The abbreviated content is synchronized, and the extracted thumbnails are correspondingly displayed in the home information center and the home network content directory of each terminal when needed. The goal of abbreviated content synchronization is to synchronize with the directory without the user intervening. In the directory, the thumbnail content can be directly browsed according to the user selection. The priority and real-time requirements of the abbreviated content, after the content of the directory, but before the full content. In this embodiment, after the directory level synchronization, the system automatically selects the abbreviated content synchronization timing according to the current system communication status and the current location of the terminal, and the timing selection depends on the network time period and the network busy condition.

According to the network time period selection, when the terminal is in the remote roaming state, the mobile phone roaming as shown in FIG. 3 is outside the home network local area network. At this time, there is a difference in the network tariff, and the bandwidth usage of the network is It also varies from time to time. The terminal system can set a lower period of the tariff as the abbreviated information synchronization time, and then the system or the terminal randomly determines a starting point during this period, and starts the transmission of the abbreviated information to achieve synchronization.

According to the network busy condition, when the terminal and the information center are in the LAN range of the home LAN, the information center completely grasps the state of the network, and can decide the delivery timing of the abbreviated information according to the busyness of the network. If the network is busy, then wait, the network is idle, and initiate abbreviated information transmission.

Full content synchronization is performed after directory level synchronization, and any terminal in each terminal stores a specified part stored in the local home network content to the home information center, and the home information center completely stores the designated part in the other terminal. One or more.

Specifically, the information characteristic of the complete content is that the storage capacity is large, and the communication resources required for the storage transfer are large. Content produced from the terminal is first saved locally. Information transfer and storage of complete content is divided into end-to-end and end-to-end transfers.

The end-to-end of the home content management system is different from the end-to-end of peer-to-peer communication. There are three nodes end-to-end in home content management: source, information center, and destination. After the end-to-end transfer decision is determined, there will be a difference depending on whether the content of the source end already exists in the information center. If the content is not in the center, the communication path is from the source to the information center, and then to the destination; if the center already has the complete content, the communication path is from the information center to the destination. End-to-end complete content does not actively transfer storage, only passive transfer, that is, only the transfer is initiated according to the user's operation, and the two user operations can complete the transfer of the complete content.

The first type is initiated by the source user. The source user specifies the destination terminal, and shares some content of the source end to the destination end. The other is initiated for the intended end user. The destination terminal user, when it is found that there is a non-native terminal generated, and there is no browsed content, click to read or browse the detailed content.

End-to-center transfer storage, both passive transfer and system active transfer. The system active transfer refers to the content production terminal. When the information center is in the same LAN range as the information center, the information center actively initiates communication according to the busy and idle state of the network, and transfers the terminal content to the home information center. This has two advantages, one is Data backup, so as to avoid loss of content due to terminal loss; Another time can shorten the time for other terminals to access content. When other terminals need to browse for new content, the complete content is directly transmitted from the information center to the destination terminal, and the content is reduced. The access problem brought by the terminal offline.

In summary, after the directory-level content is updated, after another terminal user discovers the content update from the directory, there may be the following operations:

1, not eager to browse, do not operate.

2, want to understand the big news, brush the directory, browse the abbreviated information.

3, want to know the details, click on the file, browse the full content.

For the first one, the system does not respond. The second type, that is, the abbreviated content delivery. The content source terminal extracts new content abbreviated information. In the third type, the complete content is directly transmitted from the source terminal to the information center, and the information center is delivered to the destination terminal.

In the information center, extract the abbreviated information from the complete content to prepare for other terminals. In the destination terminal, the abbreviated content is extracted from the complete content to prepare for the next browsing.

The following is another application example of the present invention, assuming that there is a gateway, a home server, a television, a mobile phone, and a PAD in a home. Home gateway supports wifi/ethemet network; home server supports wifi/ethemet network and high definition multimedia interface (HDMI, High Definition Multimedia Interface ); TV supports both cable/dvi and HDMI interface to connect to computer; mobile phone supports _w ifi/gsm/3G/lte, pad supports wifi/gsm/3G/lte. The home server is connected to the TV via an HDMI interface. The home server has very powerful processing power, large-capacity storage, fixed IP, and can be connected to it via ethernet or wifi. Wifi is family-owned, and there is no charge for wifi interconnection in the home; gsm/3g/lte is the carrier network for paid consumption.

For example, the mother in the family takes the child to travel to the field, the father goes to work as usual, and the old man retire most of the time at home. Mother used PAD to take pictures of 200 children, 10 of which were renamed; and also recorded multi-segment videos. In the background, the home network content management system on the PAD has accessed the ethernet through the 3G network and found the home server. The photo catalog and video catalog in the home server are updated.

The old man at home, switched the TV to HMDI, connected to the home server, and found two directories with photo updates and video updates, of which 10 photos were specially named. Since browsing photos produces 3G traffic, the old man only viewed 10 specially named photos, and the rest was not viewed. In the backstage, when the old man browses 10 photos, the content of the photo is uploaded from the PAD to the home server. The data exchange equipment on each node from the tourist destination to the home participates in this transmission process, and both power resources and communication resources are occupied. After the transfer of the photo content is completed, the directory in the home server is changed, and the photo is marked as being stored in the pad and also in the home server for the elderly to browse.

When Dad opens the phone after work, he finds new information on the photos and videos in the home content directory on the phone. Similarly, Dad also saw 10 specially named photos, not only stored on the mother's PAD, but also transferred to the home server; other photos, video files are all on the mother's PAD. In the background, the synchronous operation initiated by the mobile phone after the phone is turned on, so that the directory of the home network content in the mobile phone is immediately updated by the directory of the home server, and the mobile phone directory version is consistent with the server. Dad clicks on the 10 photos, the file attributes in the directory Once again, the 10 photo attributes specifically marked are marked as being stored in the home server, mobile phone, and PAD.

When Dad returns home, he turns on the TV, browses the photos on the big screen, and chooses to synchronize the full content of the photos when the network is idle at night, and the traffic is cheap. The preview image is transmitted to the home server, so 200 pictures are taken. The synchronization is on the home server. Then, through the home network wifi, the 200 photos obtained by the server are imported into the mobile phone.

In the home network, when the mother and child travel ends, take the PAD back home, the system detects that the PAD enters the free wifi area, and transfers all the photos and video content to the server; the pictures and videos in the PAD can be freely Delete without causing loss of information.
