Embodiment
For technical problem, technical scheme and advantage that the embodiment of the present invention will be solved are clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The embodiment of the present invention provides a kind of shared method for recording, as shown in Figure 1, comprising:
Step 11, receives the document recording request of recording the first file that user need to generate according to self in the second Set Top Box;
Step 12, according to described document recording request, adds document recording task;
Step 13, synchronous described document recording task, to the first Set Top Box, makes described the first Set Top Box can carry out described document recording task, the first file described in Record and Save.
The document recording request that what the embodiment of the present invention generated in the second Set Top Box according to user record the first file, add document recording task, and be synchronized to the first Set Top Box, carry out execute file recording task by the first Set Top Box, Record and Save the first file, realize the setting of sharing recording task between different Set Top Box, reached object of the present invention.
Preferably, described the first Set Top Box is the Set Top Box with this locality storage; Described the second Set Top Box is the Set Top Box without this locality storage.
Because the second Set Top Box is stored without this locality, can not recorded file, therefore, user has generated after document recording request in the second Set Top Box, according to document recording request, add document recording task, and be synchronized to the first Set Top Box, carry out execute file recording task by first Set Top Box of storing with this locality, realized equally the setting of sharing recording task between different Set Top Box.
In general, the first Set Top Box and the second Set Top Box are in consolidated network, described network is home network, in the time having first Set Top Box with this locality storage in home network, just can realize the setting of the second Set Top Box and the shared recorded file of the first Set Top Box of not being with local storage, when first Set Top Box of storing when band this locality is multiple, preferably, step 13 should be specially:
Synchronous described document recording task, to primary set-top box, makes described primary set-top box can carry out described document recording task, the first file described in Record and Save; Described primary set-top box is in described the first Set Top Box.
In the first Set Top Box of the local storage of multiple bands, select one as primary set-top box, can before request recorded file, just be selected by user.Primary set-top box execute file recording task, the first file described in Record and Save, has saved the memory space of hard disk in the same family network.
After having recorded, further, described method also comprises:
Step 14, the playing request of described the first file is play in reception user request in the second Set Top Box;
Step 15, sends described playing request to described primary set-top box, and described the second Set Top Box is arrived in the address that makes described primary set-top box return to described first file corresponding with described playing request, and described the second Set Top Box is play according to the address of described the first file.
The file of recording is kept at in local primary set-top box, in the time that needs are play recorded file, user does not need just can carry out the broadcasting of recorded file to the position of the first Set Top Box, thereby realize different user and play different program recordings, further, can increase understanding and the interest of user to IPTV business, thereby increase operation income.
The shared method for recording that the embodiment of the present invention provides, preferably, can be for following equipment:
< server >
When described method is used for server, the first Set Top Box of the local storage of band, second Set Top Box of not storing with this locality and described server are in consolidated network.First server receives the document recording request of recording the first file, the recording request is here that user need to generate and send to described server by the second Set Top Box according to self in the second Set Top Box, then according to described document recording request, add document recording task, then synchronous described document recording task is to the first Set Top Box, can carry out described document recording task by described the first Set Top Box, the first file described in Record and Save.
