In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the drawings and specific embodiments, describe the present invention.
It should be noted that, the collection of drama in the embodiment of the present invention refers to a series of multimedia files that are mutually related in content, and each collection multimedia file has common collection of drama title conventionally, but has successional rule in numbering.For example each in TV play collects: the The Romance of the Three Kingdoms the 1st collection, the The Romance of the Three Kingdoms the 2nd collection, the The Romance of the Three Kingdoms the 3rd collection etc., again for example with a series of program: Kangxu has come 131202, Kangxu has come 131203, Kangxu has come 131204 etc., more for example a film carried out to 3 parts that form after cutting: Titanic part1, Titanic part2, Titanic part3.But it should be noted that, the collection of drama in the present invention is not limited to the multimedia file of video type, applicable equally for the broadcast program such as continuous, audio frequency playlet etc.
Embodiment mono-,
The method flow diagram of the broadcasting collection of drama that Fig. 2 provides for the embodiment of the present invention one, in the present embodiment, DMC be take mobile phone as example, multimedia file be take video as example, apparatus for media playing be take TV as example, DMR be take shadow rod as example, and the present invention is not limited to the concrete form of DMR certainly, also can adopt the equipment of other forms.As shown in Figure 2, the method can comprise the following steps:
201: mobile phone sends to shadow rod according to user's selection by the user-selected broadcast address when last collection video and when the video name of last collection video, wherein in this video name, comprises collection of drama title and collection of drama numbering.
When user manually selects to play a certain collection video on mobile phone, mobile phone can send to DMS by the video name of user-selected video (comprising collection of drama title and collection of drama numbering), and from DMS, receives the broadcast address of the user-selected video returning.
For example, user selects to play " The Romance of the Three Kingdoms the 1st collection " on mobile phone, mobile phone sends to DMS by " The Romance of the Three Kingdoms the 1st collection ", and DMS returns to mobile phone through inquiry by the broadcast address of " The Romance of the Three Kingdoms the 1st collection ", then by mobile phone, the broadcast address of " The Romance of the Three Kingdoms the 1st collection " is sent to shadow rod.
Also have a kind of situation, user selects to play a certain collection video of mobile phone this locality, and the last collection video of working as that now mobile phone can be selected user sends to shadow rod in the address of mobile phone this locality as broadcast address.
202: shadow rod obtains when last collection video according to the broadcast address receiving, and offer TV and play.
If when the last collection video video that is DMS, shadow rod obtains when last collection video from DMS according to the broadcast address receiving, and offer TV and play, shown in Fig. 2 is this kind of implementation.If when the last collection video video that is mobile phone this locality, shadow rod obtains when last collection video from mobile phone according to the broadcast address receiving, and offer TV and play.
The application scenarios of the embodiment of the present invention is mainly used in, and shadow rod Real-time Obtaining video flowing also offers the mode that TV is play, and the fluency in order to guarantee to play, also can take some such as the mode of pre-buffering certainly.But for shadow rod download video stream offer mode the present invention that TV plays and support equally in advance.
203: mobile phone detects shadow rod when the broadcasting residual time length of last collection video, if work as the broadcasting residual time length of last collection video, is less than or equal to the first residual time length, carries out 204.
In order to guarantee the connection between mobile phone and shadow rod, coming the connection between detection of handset and shadow rod whether to disconnect by transmission DLNA heartbeat message between mobile phone and shadow rod, if disconnected, re-establish connection.In this step, can utilize DLAN heartbeat message to work as the broadcasting residual time length of last collection video.Main but be not limited to following several implementation:
First kind of way: mobile phone periodically carries and detects the request mark of playing residual time length in DLNA heartbeat message, and shadow rod receives after the DLNA heartbeat message that comprises this request mark, replys and comprises the DLNA heartbeat message of playing residual time length.
The second way: mobile phone periodically carries and detects the request mark of playing residual time length in DLNA heartbeat message.Shadow rod receives after the DLNA heartbeat message that comprises this request mark, can do by myself and do a judgement, if play residual time length, be less than or equal to the second residual time length, reply and comprise the DLNA heartbeat message of playing residual time length again, if play residual time length, be greater than the second residual time length, can reply and not comprise the DLNA heartbeat message of playing residual time length.This second residual time length is more than or equal to the first residual time length.
Give an example, mobile phone periodically carries and detects the request mark of playing residual time length in DLNA heartbeat message, shadow rod receives after the DLNA heartbeat message that comprises this request mark, if determine that the broadcasting residual time length when last collection video starts to be less than 6 minutes, just start reply and comprise the DLNA heartbeat message of playing residual time length.If the broadcasting residual time length of carrying in the DLNA heartbeat message that mobile phone receives is less than or equal to 5 minutes, the broadcast address of next collection video is sent to shadow rod.
The third mode: shadow rod is when obtaining when last collection video, total duration information when last collection video can be synchronized to mobile phone, mobile phone can be play estimating of residual time length according to total duration information, when the residual time length of estimating when mobile phone is less than or equal to the 3rd residual time length, in DLNA heartbeat message, periodically carry again and detect the request mark of playing residual time length, shadow rod receives after the DLNA heartbeat message that comprises this request mark, replys and comprises the DLNA heartbeat message of playing residual time length.The 3rd residual time length is more than or equal to the first residual time length.
Give an example, shadow rod is when obtaining when last collection video, total duration information when last collection video can be synchronized to mobile phone, it is for example 40 minutes, mobile phone can be estimated playing residual time length, when the residual time length of estimating when mobile phone is less than or equal to 10 minutes, starts periodically to carry in DLNA heartbeat message and detects the request mark of playing residual time length, shadow rod receives after the DLNA heartbeat message that comprises this request mark, replys and comprises the DLNA heartbeat message of playing residual time length.If the broadcasting residual time length that mobile phone receives is less than or equal to 5 minutes, the broadcast address of next collection video is sent to shadow rod.
The above-mentioned second way and the third mode first kind of way of comparing, has reduced the network between mobile phone and shadow rod has been taken.
204: mobile phone is determined the collection of drama index id of next collection in same collection of drama according to the collection of drama index id when last collection video.
For the collection of drama of TV play class, conventionally the mode that respectively collects collection of drama numbering employing serial number in video, and be not that all collection of dramas are not always the case, such as variety show class collection of drama, what collection of drama numbering adopted conventionally is to play the date, and play the date, be not likely successional, if adopt collection of drama numbering to be difficult to determine exactly the collection of drama numbering of next stage video.But in most cases, respectively collect video council and have index id in a series of collection of dramas, index id is present in video inside, and the index id in same collection of drama is serial number, shadow rod can obtain index id information when getting video conventionally.Therefore, in embodiments of the present invention, shadow rod, when getting when last collection video, can be synchronized to mobile phone by the index id when last collection video, and mobile phone utilization collects the index id of video when the index id of last collection video determines next.
Certainly, if broadcasting is the video of mobile phone this locality, mobile phone itself just can obtain the index id that respectively collects video, synchronous without carrying out.
205: mobile phone sends to DMS by the collection of drama index id of next collection video, and receive the broadcast address of next collection video that DMS returns.
If collection of drama is the video from DMS, the collection of drama index id that mobile phone can collect next video sends to DMS, to ask the broadcast address of next collection video; If collection of drama is local from mobile phone, the collection of drama index id that mobile phone can collect video according to next determine next collection video in the address of mobile phone this locality as broadcast address.The video of playing from DMS of take in Fig. 2 is example.
206: mobile phone sends to shadow rod by the broadcast address of next collection video and video name.
It should be noted that, in embodiments of the present invention, it is mainly for shadow rod, to carry out the demonstration of playlist that mobile phone sends to the object of shadow rod by video name, is not that the present invention is necessary.
207: shadow rod is added into broadcast address and the video name of next collection video in video play lists.
This step shadow rod can collect next the broadcast address of video and video name and join in video play lists after last collection video.After finishing when last collection video playback, shadow rod will automatically obtain next collection video according to the broadcast address of next collection video and control TV and automatically play next collection video like this.
After this, shadow rod offers the in progress video of TV just as when last collection video, goes to 203 and starts to move in circles.If in 205, mobile phone cannot receive the broadcast address of next collection video from DMS, and this may be because the reasons such as network or equipment cause, and mobile phone can repeat 205 with request broadcast address.For example, if but repetitive requests still cannot receive the broadcast address of next collection video for N time, N is default positive integer, gets 3, is likely that collection of drama finishes, there is not next collection, now can process ends.
If in carrying out the process of above-mentioned flow process, mobile phone receives the video that user selects, interrupt above-mentioned flow process, preferential answering user's selection, be that mobile phone can send to shadow rod by the broadcast address of the video of user's selection, in order to distinguish video that user selects or the video of chain broadcast automatically, can in the message that sends video playback address, carry a flag bit, whether be used to indicate is the video that user selects, if this flag bit indication is the video that user selects, shadow rod obtains video immediately according to the broadcast address of this video, this video being put into the first place of playlist plays.
