Definitions
- the invention relates to a method for reproducing audio documents from a reproduction apparatus, and to a reproduction apparatus. provided with a graphical user interface allowing selection.
- the storage of a large number of audio documents in consumer equipment is known.
- the reproduction apparatus is provided with an interface making it possible to easily find the document desired by the user.
- the reproduction devices are, for example, portable audio CD players, portable players containing a hard disk (such as the MP3 Lyra model marketed by the applicant) capable of storing 300 hours of music, living room players with display and remote control , personal computers with screen, hard drive, CD player and keyboard.
- the user must enter the precise identifier of the audio document to be reproduced.
- it In the case of audio CDs, it must program the CD number and the song number within this CD.
- the reproducing apparatus is provided with a reader which displays the identifier of the audio document being reproduced.
- the LYRA MP3 player has a small LCD screen allowing the selected functions to be displayed in the form of icons, and the numbers of the audio tracks.
- Living room equipment has a large capacity hard drive, 20 Gigabytes for example, which can store thousands of sound content.
- the graphic interface consists of a large screen allowing to display more information, the full title of the song for example.
- the selection of audio documents is made by a number or by an identifier from a list displayed on a screen. With the increase in storage means, the number of documents to be stored is greater and therefore, the user can spend some time searching for the one that interests him.
- the reproducing apparatus can create groups.
- the attributes of audio documents are for example the genre (classical music, pop, choral, jazz, ...), the title, the producer, the singer, the publishing house ....
- groups having a certain musical unit are for example the genre (classical music, pop, choral, jazz, ...), the title, the producer, the singer, the publishing house ....
- the user can first select a group and then navigate inside it to search for a song.
- the group identifier is then the attribute common to the documents.
- certain audio content accessible to a user does not automatically have these attributes, for example when the user records his own musical pieces live. In this case, another way to classify audio documents is to analyze the audio signals directly.
- the group identifiers can be entered by the user according to the documents contained in the group at a given time. But when new documents are uploaded, group identification should be able to evolve to better define the group. In addition, if a lot of documents are assigned to a group, it may be worth splitting it into several groups to obtain medium-sized sets of documents. Such an operation obliges the user to redefine the identifiers.
- Japanese patent JP07-044575 discloses a voice recognition process for processing voice documents or voice sources and placing them in a video. The vocal contents are represented in a space (“sound field space”) by symbols which one can select using a mouse. The user moves in the "sound field space” using the mouse. The documents are grouped according to a hierarchical structure.
- One of the objects of the present invention aims to offer the user an automatic means for classifying documents into groups and easily identifying them for the user. Then in a powerful and user-friendly way, the user navigates from group to group, as well as within a group.
- the subject of the invention is a method of reproduction within an apparatus for reproducing audio documents, characterized in that it comprises the following steps: - partitioning of the documents into groups of documents having at least one similar audio characteristic, - determination at least one audio document representing each group, - positioning of a plurality of audio documents in a space, the positioning of an audio document being a function of at least one characteristic of the document, the user occupying a position in said space - reproduction of at least one identifier of a document representing a group, the reproduced identifier or identifiers having a position situated at a distance less than a determined distance from the position of the user in space.
- the device itself determines the groups of audio documents and at least one document representative of the group, an identifier of the representative document or documents being highlighted graphically and / or hearing the user.
- the user can realize the type of music it is and can select this group and elements of this group in order to reproduce them.
- the user can activate a command making it possible to pass from one group to another, the identifiers as well as the reproduced documents are automatically updated according to the current document group.
- the user can by activating a command reproduce the documents within the group whose identifier is reproduced.
- the method comprises a step of representing documents in a space whose number of dimensions is equal to that of the audio parameters, and whose documents are associated with points arranged within this space.
- the determination of a document representing a group is determined as a function of the distance between the equibarycenter of the points associated with the documents of the group and the point associated with this document.
- the document whose associated point is closest to the equibarycenter is considered to represent the group.
- the method comprises a step of projecting onto a space of determined size of the points associated with the documents of the set and having as audio coordinates the audio parameters. In this way, we can show all the documents by graphically representing the projection space.
- the invention also relates to an apparatus for reproducing audio documents, comprising a command input means; characterized in that it further comprises a calculating means for partitioning documents into a group of documents having at least one similar audio characteristic, a means of determining at least one document representing each group, a means of calculating data from positioning associated with each document in a space, the data being determined by at least one characteristic specific to the document, positioning data also being assigned to the position of the user within the space, a means of selecting at least at least one document representing a group, the selected document or documents having a position situated at a distance less than a determined distance from the position of the user in space, a means of reproducing at least one identifier of at least one document representing a group.
- FIG. 1 is a block diagram of an example of an audio document reproduction apparatus for implementing the invention
- - Figure 2 is a table associating for each document in the collection its low-level parameter values
- - Figure 3 represents a projection on a two-dimensional space of the points associated with documents belonging to three groups
- the receiver comprises a central unit 3 connected to a program memory 12, and an interface 5 for communication with a high speed local digital bus 6 making it possible to receive high speed audio and / or video data.
- This network is for example an IEEE 1394 network.
- the receiver can also receive audio and / or video data from a broadcasting network through a receiving antenna associated with a demodulator 4, this network can be of radio or television type.
- the receiver further comprises an infrared signal receiver 7 for receiving the signals from a remote control 8, a memory 9 for storing a database, and an audio / video decoding logic 10 for the generation of the audiovisual signals sent. on the television screen 2.
- the remote control 8 is provided with the direction keys, ⁇ , -_ and - and with the keys: "OK", “Group”, “audio documents” and “Select” which we will see later function.
- the receiver also includes a circuit 11 for displaying data on the screen, often called an OSD circuit, from the English “On Screen Display” (literally meaning "display on the screen”).
- the OSD circuit 11 is a generator of text and graphics which makes it possible to display on the screen menus, pictograms or other graphics, and menus presenting the navigation.
- the OSD circuit is controlled by the Central Unit 3 and a browser 12.
- the browser 12 is advantageously produced in the form of a program module recorded in a read only memory.
- the digital bus 6 and / or the broadcasting network transmit audio content to the receiver either in digital form or in analog form, the receiver recording them in a memory 9.
- the audio content is received in the form digital, preferably encoded according to a compression standard, MP3 for example, and stored in the same form.
- the memory 9 is a large capacity hard drive, 40 gigabytes for example.
- the storage of a minute of audio content in MP3 occupying about 1 Megabytes, such a disc is capable of recording 666 hours of audio document. Downloading audio content is a well-known technique which need not be explained in the present application.
- a browser software module analyzes each audio content when it is received and extracts the low-level parameters.
- the number of elements of a descriptor is of the order of a few tens.
- the table contained in the screen page of FIG. 2 presents the values of low-level parameters constituting the descriptors of a certain number of audio documents.
- the first column of the table presents the title of the audio content, each content is numbered.
- the following columns present the values of low level parameters associated with the document, such as the average sound intensity, the tempo, the energy, the rate of passage through zero (or “zerocrossing” in English), the brightness (or " brightness ”in English), the envelope, the bandwidth in“ bandwidth ”
- FIG. 3 represents a two-dimensional space where the points corresponding to three groups of documents, denoted AB and C, are arranged.
- the coordinates (xi, yi) of each point are obtained by projection of the point Pi on a space of dimension 2.
- the projection is determined by principal component analysis or PCA.
- PCA principal component analysis
- the PCA is notably described in the document Saporta 1990, entitled “Probability Analysis of data and statistics, Technip Edition. This well-known data analysis algorithm seeks to discover a subsystem of axes linked linearly to the original which “spreads” the samples as well as possible, these axes tend to confuse the correlated original axes.
- the document whose point (xi, yi) is closest to the equibarycenter of a group is considered to be the representative of the group.
- the step of projecting the points on a space in one, two or three dimensions makes it possible to create a graphic representation of the collection of documents accessible from a device.
- the distance calculations between the equibarycenter and each point associated with a document of a group is simpler, because the number of dimensions of the projection space is much lower than the number of low-level parameters.
- the point associated with the document is of a certain shape (as shown in Figure 3), or of a certain color, or any other distinctive graphic characteristic.
- Such a graphical representation constitutes with a keyboard a user interface making it possible to select any point within a group. For this, the user can jump from one point to another by indicating a navigation direction using the direction keys. But the stage of projection on a space with one, two or three dimensions is optional, because one can perfectly determine the equibarycenter of a group of points arranged in a multidimensional space, in the same way one can calculate the distances separating any which point of the group with the equibarycenter. In this case, it is difficult to represent the documents with points, the graphical interface then only presents graphical group identifiers.
- FIG. 4 An example of a graphical interface is presented in FIG. 4. In FIG. 4, an image appears in the background and a set of graphical group identifiers.
- a group graphic identifier is an icon containing a number varying from 1 to the number of groups calculated during the group determination step. These identifiers are linked by a graphic link giving an indication to the user of the navigation command to activate to change groups.
- group 7 is selected, by pressing the direction key
- group 6 is selected, and by pressing the direction key ⁇ , group 8.
- the icon containing the group current is highlighted by a bold outline, or by a highlight, or by a flashing or a colored background. If the icons are arranged horizontally, the user uses the arrow keys -> and - to change groups.
- the device plays the audio document representing the group.
- a variant consists in that a determined number of audio documents represent the group. According to this variant, these documents are reproduced in a loop when the group is selected. Representative documents are for example those located at a distance less than a determined value of the equibarycenter.
- An improvement of this variant consists in that the user himself determines the number of documents representing each group. In this way, the user can start the reproduction of a large number of documents having auditory continuity and this having to select them manually.
- the first document selected by the program as a representative is that of the group whose distance is the shortest from the equibarycenter, then the second, then the third and so on.
- This reader is portable and autonomous, it has a battery 5.2, a Central Unit 5.3 (CPU) connected to a program memory 5.12, a keyboard 5.8 allowing the user to enter all the commands necessary for reproduction audio content, a 5.10 audio interface comprising at least one D / A converter, at least one preamplifier whose gain is adjustable by the UC 5.3 and an amplifier sending the amplified sound signals to at least two 5.11 speakers.
- the 5.8 keyboard has four direction keys and a rotary element allowing to introduce a movement of rotation to the left or to the right, classic commands of reproduction of an audio document (reading, fast forward, fast backward, off, volume control), a rotary selector and at least one dial.
- Audio content is advantageously recorded on a 5.9 hard disk, but any other recording medium may be suitable, in particular removable media (audio CD, DVD, magnetic cartridge, electronic card, etc.). Audio content can be downloaded to the hard drive 5.9 in the same way as that described for figure 1. Downloading audio content is a well known technique which need not be explained in this document. Once a certain number of audio contents memorized in the memory 5.9, the user wants to select them and to reproduce them. To do this, the program analyzes each audio content and extracts the low-level parameters. The signal analysis techniques are identical to those indicated above for the device described in FIG. 1.
- the audio documents Di accessible from the reader are virtually represented by Pi points arranged in an n-dimensional sound space.
- this second exemplary embodiment uses a two-dimensional sound space.
- the diagram in FIG. 6 illustrates such an arrangement.
- the positions of the points Pi defined by their coordinates (xi, yi) within the sound space, are calculated from the low level parameters.
- a point Pi is an identifier representing a sound document Si.
- the coordinates (xi, yi) are obtained by projection of the point Pi whose coordinates are the values of the low level descriptors on a sound sample, on a space of dimension 2, 3, etc., according to the type of representation chosen.
- the projection from the descriptor space to this 2-dimensional space is determined by a principal component or PCA analysis.
- the PCA is notably described in the document Saporta 1990, entitled “Probability Analysis of data and statistics, Technip Edition".
- the purpose of this data analysis algorithm is to determine a subsystem of axes linked linearly to the original which “spreads” the documents as well as possible, these axes tend to confuse the correlated original axes.
- the program can analyze the sound documents and determines the main dimensions itself, then the program chooses the number of dimensions of the sound space.
- the document collection can be represented by a space with more than two dimensions. We can thus create a three-dimensional sound space where the user evolves.
- the installation must be equipped with additional 5.11 speakers, and arrange them at the top and bottom so as to give the user the impression that the sound is also coming from the top or bottom.
- the low level descriptors being supposed to have a perceptible coherence and the projection being continuous, the close points correspond to sounds perceptually close.
- the coordinates ⁇ Xi, y 2 , ... zi ⁇ of a point Pi in a multidimensional space allow the user to determine the type of the associated audio document.
- the diagram in Figure 7 illustrates the details of the 5.10 audio interface.
- the 5.10 audio interface consists of two identical parts, one for reproduction on the 5.11 left earpiece and the other for the 5.11 right earpiece.
- the number of documents selected by the program must be low, five for example.
- the CPU 5.3 associated with its program stored in memory 5.12 controls five selectors S1, S2, S3, S4 and S5 whose functions are to select a document from the set of audio documents in memory 5.9 and reproduce it.
- the five audio signals selected by the selectors Si are transmitted respectively to five preamplifiers A1, A2, A3, A4. and A5, the gains of which are controlled by the UC 5.3.
- the gain of a preamplifier Ai reproducing an audio document Di is proportional to the distance in the sound space separating the point (xu, yu) and the point Pi with coordinates (xi, yi) associated with this document. The gain also depends on the direction in which the point (xi, yi) is situated in relation to a straight line starting from the point (xu, yu) in the direction facing the user placed in the sound space. This line is represented by an arrow in FIG. 7.
- a variant consists in implementing a "Selection" key on the keyboard 5.8 of the reader 5.1.
- the program selects the audio document closest to the point (xu, yu) where the user is virtually located and orders its reproduction to the exclusion of any other document.
- the position (xu, yu) is memorized so that a second press on the "Selection" key returns to the previous state where the five sound documents closest to the position of the point (xu, yu) are reproduced.
- the five documents closest to the point associated with the user are also close by hearing, so that it is not easy for the user to determine an axis of movement according to a particular type of music for example .
- a first improvement consists in determining groups of audio documents having auditory coherence, and in reproducing one or more documents called "representative (s)" of each group.
- the determination of the groups can be carried out only as previously described, for example by comparing the values contained in the descriptors of the audio documents, whether they are downloaded or calculated locally, and by grouping those whose values are close.
- the representative of a group is the audio document whose point is located closest to the center of the nebula of points of each audio document of the group. Its identifier is audio content.
- the representative is a succession of documents or extracts from the documents of the group
- the identifier is then a sound content constituted by the successive reproduction of extracts from each document representing the group, each extract being reproduced for 10 seconds for example.
- the extracts are reproduced in a loop.
- the program produces a synthetic sound calculated from an average of the low level parameters characteristic of the group's audio documents.
- the assignment of a document to a determined group is done by adding a new column to the table of descriptors in Figure 2, this new column contains the number identifying the group to which the document belongs.
- four groups have been identified by contours.
- a variant of the "group" key consists in considering the speed of movement as a means of selecting the navigation mode and the way of calculating the groups.
- the user moves by pressing the four direction keys, when he presses a key for a long time or successively and quickly, the program considers that the user wishes to increase the speed of movement.
- a single short press on a button returns to normal travel speed.
- a variant consists in implementing a wheel on the keyboard 5.8 allowing the user to finely determine the speed. In the event of rapid movement, the program creates few large groups.
