Embodiment
Describe the embodiment of the invention in detail below with reference to accompanying drawing.
At first, with reference to the information processing method of Fig. 1 description according to the embodiment of the invention.
Can be applicable to electronic equipment such as intelligent television according to the information processing method of the embodiment of the invention.It is pointed out that in this manual described intelligent television not only can comprise television set itself, also can comprise associated components such as set-top box.
Described electronic equipment comprises display unit, is used for showing the video file of described electronic equipment this locality or the TV programme of broadcasting.Described electronic equipment also can comprise memory cell, is used for storing the information of audio file for example etc.Described memory cell can be built in described electronic equipment, also can be used as peripheral hardware and removably is connected with described electronic equipment.In addition, described electronic equipment also comprises communication unit, is used for communicating by letter with TV station or remote server via cable network or wireless network, to obtain TV program information.Described communication unit also can be by communicating such as infrared radio communication and remote controller, to obtain the instruction for the operation of the described electronic equipment of control.
When the information processing method of the embodiment of the invention began, the user used described electronic equipment to watch for example TV programme or local video, and found that the TV programme of playing this moment is relevant with its interested song.At this moment, as shown in Figure 1, at step S101, described information processing method receives first instruction.Particularly, described information processing method receives the associated instructions of described first instruction of conduct that the user sends by described remote controller.Certainly, described information processing method also can receive the associated instructions of described first instruction of conduct that the user send by the operation input section of described electronic equipment.
Next, at step S102, described information processing method obtains multimedia file according to described first instruction.Particularly, when the current content displayed media stream file that to be described electronic equipment obtain from TV station or remote server, described information processing method begins described media stream file is recorded in the memory cell, thereby obtains described multimedia file.When current content displayed was the multimedia file of the local storage of described electronic equipment, described information processing method obtained described multimedia file from the memory address of described multimedia file.
After this, at step S103, described information processing method is determined and described multimedia file corresponding audio files.
Particularly, in one embodiment, described audio files storage is in the memory cell of described electronic equipment, and the user comprised information about described audio file in described first instruction, for example about the information of the memory address of described audio file.Thus, described information processing method is determined and described multimedia file corresponding audio files according to the information about the memory address of described audio file that comprises in described first instruction.
In another embodiment, described audio file is not stored in the memory cell of described electronic equipment.Similarly, the user has comprised the information about described audio file in described first instruction, for example, and the name information of described audio file.Thus, described information processing method is according to the information about the title of described audio file that comprises in described first instruction, determine and described multimedia file corresponding audio files, and by described communication unit visit remote server, download described audio file from described remote server.
Next, at step S104, described information processing method extracts first characteristic information of described multimedia file and second characteristic information of described audio file.Particularly, described information processing method can extract for example spectrum information in the audio component of described multimedia file, as described first characteristic information.Similarly, described information processing method can extract for example spectrum information in the described audio file, as described second characteristic information.The mode of described information processing method extraction spectrum information is known to those skilled in the art, is not described in detail in this.
It is pointed out that above is that example is described with spectrum information as characteristic information.Yet, it will be understood by those skilled in the art that described first characteristic information and described second characteristic information not only can be the characteristic informations of frequency domain, can also be for example temporal signatures information, time-frequency characteristics information and audio fragment characteristic information etc.
In addition, described information processing method also can obtain the time span information of described multimedia file and described audio file respectively.Described time span information can be used as the part of described characteristic information, also can be independent of described characteristic information.In other words, described information processing method can also can obtain the time span information of described multimedia file and described audio file in step S102 step in addition at step S102.
After this, at step S105, described information processing method is associated described audio file based on described first characteristic information and described second characteristic information with at least a portion of described multimedia file.
Be that spectrum information is that the situation of example is described with described first characteristic information and described second characteristic information below.In the case, described information processing method is based on the specific fragment in the spectrum information of described audio file, searches for the coupling fragment that is complementary with described specific fragment in the spectrum information of described multimedia file.Described information processing method can be searched for described coupling fragment based on various audio search methods known in the art, is not described in detail in this.
After this, described information processing method will be corresponding with the starting point of described coupling fragment, the moment of described multimedia file in time domain be made as synchronous start point.In addition, as mentioned above, described information processing method obtains the time span information of described audio file.Thus, described information processing method can be associated the part that begins to continue described time span from described synchronous start point in the described multimedia file with described audio file.
More specifically, under the described audio file situation identical with the time span of described multimedia file, described information processing method can be associated the audio-frequency information of described audio file with all audio frequency component of described multimedia file.
