It is also preferred that the left due in the first situation user terminal can be directly obtain remote server address and device identification, it is possible to so that receiving remote server address and the device identification that other user terminals send, then the first obtaining step 11 particularly as follows:

First scanning step 111, scans and is controlled to carry out the Quick Response Code of display on the video playback apparatus of video playback by remote server, obtain the described remote server address of record in described Quick Response Code and the device identification of video playback apparatus；Or

Reception processes step 112, receives other user terminals and performs described remote server address and the device identification that described first scanning step 111 obtains.

Concrete, network topology structure when only performing the first scanning step 111 is as shown in Figure 4, suitable in short time interval continued broadcasting, user carries an intelligent subscriber terminal unit (such as mobile phone, panel computer, wearable device etc.) with shoot function and network insertion (such as Wifi, LTE etc.), by the server address scanning Quick Response Code shown on mobile TV and obtaining mobile TV mark and mobile TV connects, and then interact to obtain current video information can across shielding continued broadcasting with server；

And for by different terminals perform respectively the first scanning step 111 and reception process step 112 in the case of, a kind of concrete network topology structure as it is shown in figure 5, it is applicable to various scenes, as:

1, due to the difference of terminal unit, as present terminal possesses photographic head, but another terminal does not possess photographic head, but it is more applicable for the situation of video playback, after now needing present terminal to be scanned, the device identification of the remote server address obtained and video playback apparatus is sent to another terminal that described ability to play is higher, another terminal performs above-mentioned request step.

2, owing to accessing the difference of network, such as present terminal, to be in charge higher by under the mobile communications network of flow charging, and another terminal is in the network of flat rate, after now needing present terminal to be scanned, the device identification of the remote server address obtained and video playback apparatus is sent to flow and spends another terminal less, another terminal perform above-mentioned request step.

3, user need not watch this video content at once, think that alternative free time is watched with other equipment, the remote server address that then can be obtained by terminal device scans and device identification are sent to another intelligent subscriber equipment (such as smart machines such as the intelligent televisions in family or office) by instruction, subscriber equipment according to remote server address and device identification and remote server interact to obtain current video information and can across screen continued broadcasting, for the viewing of later free time.

Further, it is directed to the first situation and mainly includes 4 scenes:

First scene is, Quick Response Code only comprises remote server address and device identification, user terminal under this scene, remote server and by remote server control carry out video playback video playback apparatus perform multimedia file continued broadcasting method be concrete steps as shown in Figure 1, Figure 2 and Figure 3.

In above-mentioned scene one, under a kind of implementation, remote server can determine the current video play at video playback apparatus according to current time, and transmits from video beginning to user；But this scene needs user oneself to drag amendment playing progress rate, then have a problem that under this kind of scene, and the first half user of video watches, and being transferred to user does not have practical significance, causes that invalid data are transmitted, wastes the data traffic of user.

Therefore, in order to reduce the transmission of invalid data, in scene one, under another implementation, remote server can determine the current video play at video playback apparatus according to current time, and carry out transmission of video according to the playing progress rate that video playback apparatus is current to user terminal, process as the mirror image of video playback apparatus by user terminal.

The problem that above-mentioned mode solves bandwidth waste, but do not realize real seamless play, as: user 10:20 gets off (assuming that being now played to the 10th minute of video) after scanning above-mentioned Quick Response Code on bus, after user gets off, start to perform request step to 10:25, then under aforesaid way, server can commence play out from the 15th of video the minute.It is found that user is the 10th minute that cannot watch video to the 15th minute this section under aforesaid way.

In order to realize seamless transit, when user can utilize terminal to carry out continued broadcasting video within a short period of time, then in the second scene of the method for the embodiment of the present invention, Quick Response Code includes video playback progress msg, when then user terminal performs the first scanning step 111, described video playback can also be got and carry out information, the request of described video playback also carries described video playback progress msg, described remote server can be determined according to described video playback progress msg described video file is gone back part not broadcast, and go back part not broadcast in the described user terminal described video file of transmission.Accordingly, remote server performs also to need when step 21 determined by the first file to determine in described video file also part not broadcast according to described video playback progress msg；At least some of of described video file is go back part not broadcast in described video file.Accordingly, also need when video playback apparatus performs the second obtaining step 31 to obtain video playback progress msg, and the Quick Response Code record generated in generation step 32 has above-mentioned video playback progress msg, the request of described video playback also carries the described video playback progress msg being recorded in described Quick Response Code, described remote server can be determined according to described video playback progress msg described video file is gone back part not broadcast, and go back part not broadcast in the described user terminal described video file of transmission.

Video playback progress in above-mentioned mode can be passed through to be embodied in various ways, as:

1, percentage ratio represents, when playing 50% such as video, then above-mentioned video playback progress msg is 50%, then remote server can start transmission from the 50% of the video file determined；

2, video playback time representation, has been played to the 10th minute the 20th second such as video, then above-mentioned video playback progress msg is 10 minutes 20 seconds, then remote server can start transmission from the 10th of the video file determined the minute the 20th second.

Certainly, being only more than the description of several possible implementation of video playback progress, the embodiment of the present invention does not limit the specific implementation of above-mentioned video playback progress msg.

It is found that in above-mentioned mode, owing to have recorded video playback progress msg, therefore, it is possible to realize seamless play.

In above-mentioned scene two, may be only available for user and carry out the situation of continued broadcasting at short notice, because video playback progress is arranged for some specific video file, and this specific video file is to be worked as, by what server was determined, the video file that forward direction video playback apparatus transmits.When interval time is longer, now it is likely to server and have switched the video file transmitted to video playback apparatus.

Therefore, so that the method for the embodiment of the present invention has better adaptability (no matter user initiates video playback request when and can both realize video file continued broadcasting accurately), the method of the embodiment of the present invention also has the third scene, under this scene, Quick Response Code includes temporal information, then the first scanning step 111 also obtains above-mentioned temporal information, the request of described video playback also carries described temporal information, described remote server can be determined according to described device identification and described temporal information described video file is gone back part not broadcast, and go back part not broadcast in the described user terminal described video file of transmission.Accordingly, remote server performs also to need when step 21 determined by the first file to determine in described video file also part not broadcast according to described device identification and described temporal information；At least some of of described video file is go back part not broadcast in described video file.Accordingly, also need when video playback apparatus performs the second obtaining step 31 to obtain temporal information, and the Quick Response Code record generated in generation step 32 has described temporal information, the request of described video playback also carries the described temporal information being recorded in described Quick Response Code, described remote server is determined according to described temporal information described video file is gone back part not broadcast, and go back part not broadcast in the described user terminal described video file of transmission.
