Embodiment 1
Shown in Figure 1 is the structured flowchart of the mobile communication terminal of the embodiment of the invention 1, wherein the mobile communication terminal of present embodiment 1 is a mobile phone, this mobile phone comprises: selection instruction input unit 101 is used to import the play mode selection instruction of playing described multimedia file; Play mode determining unit 102 is used to receive described play mode selection instruction, and determines the play mode of described multimedia file according to this play mode selection instruction, and this play mode comprises normal play mode and chapters and sections formula play mode; Show chapters and sections information unit 103, be used for when described play mode is described chapters and sections formula play mode, showing the chapters and sections information of described multimedia file; Initial chapters and sections selected cell 104 is used for the initial chapters and sections of broadcast according to the described multimedia file of described chapters and sections Information Selection; Broadcast unit 105 is used for beginning to play described multimedia file from the initial chapters and sections of described broadcast.
The flow chart of the method for broadcasting multimedia file of the mobile communication terminal of the embodiment of the invention 1 that shown in Figure 2 is.
At first, in multimedia file, add chapters and sections information (step S201); Then play the play mode selection instruction (step S202) of described multimedia file by 101 inputs of user by selecting instruction input unit; Receive described play mode selection instruction, determine the play mode of described multimedia file according to this play mode selection instruction, this play mode comprises normal play mode and chapters and sections formula play mode (step S203); When described play mode is described chapters and sections formula play mode, show the chapters and sections information (step S204) of described multimedia file; The initial chapters and sections of broadcast (step S205) according to the described multimedia file of described chapters and sections Information Selection; Begin to play described multimedia file (step S206) from the initial chapters and sections of described broadcast.
At this, at first introduce the difference of analogue audio frequency and digital audio: simulated sound is continuous in time, and digital audio is a data sequence, is interrupted in time.Digital audio is by sampling and quantizes, the audio signal of analog representation is converted to by many binary numbers 1 and 0 digital audio and video signals of forming.
Basic numeral system in the computer is a binary system, we also will be write as voice data the data format of computer for this reason, this is referred to as the coded audio digitlization, audio frequency in the computer must be a digital form, therefore must convert simulated audio signal to the discrete series of limited numeral, promptly realize digitized audio frequency.
The general audio frequency of hearing in mobile phone such as mp3 all are digital audio.Audio frequency is sampled, quantize and coding, in fact be prejudicial to tonequality, after handling, audio frequency is exactly a binary code stream, be similar to 1010111000, the size of a mp3 audio frequency is about 1/10th of a cd track audio frequency, because it is in sampling, in the process of quantification and coding, removed the sound of the more unresolvable frequencies of people's ear, so sound from people's ear, tonequality does not have anything to change, because the frequency that people's ear can be differentiated probably is 20Hz～20000Hz, so we add a sign to audio frequency, can't influence the quality of audio frequency.Therefore digital audio can carry out various processing to digital audio, such as audio mixing than the easier processing of analogue audio frequency, stiffening effect or the like, the present invention need add an audio frequency sign greater than 20000Hz, by computing, be converted into code stream, and deposit in the original audio code stream.
