Definitions
- the invention relates to a method for navigating through audio documents accessible using an audiovisual receiver, and a reproducing apparatus provided with a graphical user interface for navigation.
- the storage of a large number of audio documents in consumer equipment is known.
- CD compact audio disc
- These devices also have a programming function to define a sequence of sound tracks. During this programming, the user enters for each song, the CD identifier and the song identifier in the CD. In order to have a certain melodic continuity, the user must know the songs in advance and program them in order to produce a certain sound continuity during the reproduction.
- attributes can classify content for example genre (jazz, vocal, rock, soft music, background music, etc.).
- certain audio contents accessible to a user do not automatically have these attributes, for example when the user records his own musical pieces live.
- Another way to classify audio content is to analyze sound signals directly.
- Signal analysis techniques which allow the calculation of so-called “low level” parameter values for each audio content. These parameters are for example: the tempo, the energy, the brightness, the envelope, ... They are determined by analysis of the signal either in its digital form, or in its analog form.
- An audio content indexing technique is explained in the article "Speech and Language Technologies for audio indexing and retrieval" published in August 2000 in the IEEE review pages 1338 to 1353 in volume 88.
- Such a sequence can be carried out by programming provided that the user knows the different contents in advance. And even in this case, if the user wants to obtain melodious sequences, it is not easy for him to do so if he does not have a musical ear.
- International patent application WO01 / 65346 - MIHALCHEON describes the presentation of an online product catalog. The products appear as icons on the screen and the user can select an icon which triggers the audio reproduction linked to the chosen object. The passage from one icon to another is done by navigation according to a strategy built by the catalog supplier. This navigation cannot therefore take into account objects specific to the user's terminal, nor criteria specific to the user.
- the present invention allows a user to successively reproduce audio content contained in his terminal while retaining a certain musical unity or at least a certain logic.
- the graphical interface thus defined makes it easy to navigate in a large collection of audio content and reproduce content that the user desires, and this in a powerful and user-friendly way
- the subject of the invention is a method of navigation within a collection of sound documents stored in a reproduction device provided with a display device, comprising - a step of memorizing each sound document in the collection, - a step of analyzing stored documents in order to determine audio parameters specific to each document, the method is characterized in that it comprises the following steps: - positioning of graphic identifiers corresponding to at least part of the sound documents on a page display device graphic, the position of each graphic identifier being dependent on the parameters previously calculated for a given document, - automatic navigation by selecting and successively reproducing the audio documents according to a strategy taking into account the position of the graphic identifiers of the documents in the graphic page and a geometric characteristic p to the reproductive system.
- the method proposes a new concept of navigation within a set of audio content, the concept being based on the visualization of a graphic representation of the set and of a strategy based on a graphic relationship uniting certain graphic identifiers.
- the user can see on the graphic page the evolution of the sequences of the audio documents available within his terminal.
- the position of the representations of the documents in the graphic page depends on the low-level parameters calculated for each document, therefore navigation based on the position of the representations leads to a certain auditory continuity.
- the method comprises a step of determining groups of documents having close parameter values.
- the graphic identifiers associated with the documents of a group are displayed with a similarity allowing the user to locate the group within the graphic page.
- the method comprises a step of receiving a command to launch navigation by specifying the navigation strategy used by the receiver to automatically chain the reproduction of documents.
- navigation strategy used by the receiver to automatically chain the reproduction of documents.
- the method includes a step of displaying the number of documents reproduced according to the determined strategy.
- the method includes a step of displaying the serial number of the document being reproduced.
- the invention also relates to a reproduction apparatus comprising a central unit, a means for receiving audio documents, a means for memorizing received documents, a means for entering a user command, a means for analyzing documents. stored in order to determine parameters specific to each document, characterized in that it comprises: means for displaying a graphic page of the graphic identifiers corresponding to at least part of the stored audio documents, the position of the graphic identifiers of each document being dependent on the parameters previously calculated, and a navigation means for the automatic sequence of the reproduction of documents according to a determined strategy taking into account the position of the graphic identifiers of the documents within the graphic page and a geometric characteristic specific to the reproduction device.
- FIG. 1 is a block diagram of a reproduction apparatus for implementing the invention
- FIG. 2 is a table associating for each document in the collection its low-level parameter values
- - Figure 3 describes a screen appearance showing the collection of documents in a two-dimensional space
- - Figure 4 describes a screen appearance showing a navigation strategy known as the segment for automatically chaining audio documents
- - Figure 5 describes a screen appearance showing a navigation strategy in a spiral to automatically chain audio documents.
- 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 enabling high speed audio and / or video data to be received.
- 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 to the television screen 2.
- the remote control 8 is provided with the direction keys, ⁇ , -i> and - and with the keys: "OK” and "Select", the function of which we will see later.
- 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. It can also be produced in the form of a specialized circuit of the ASIC type for example.
- 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 disk, 40 Gigabytes for example.
- the storage of one minute of audio content in fvlP3 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. Once a certain number of audio contents memorized in the memory 9.
- 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 ”, the“ Loundness ”, the cepstral coefficients
- the low level parameters can be provided in digital form with the content audio.
- the associated low-level parameters constituting a field attached to the audio content. This solution is particularly advantageous since the parameters are calculated by the producer or the content supplier and not by the user, and therefore it is carried out only once.
- the descriptors are stored in the memory 9 and then used to create groups of documents having certain similarities.
- the grouping of content into coherent groups can be achieved using an algorithm known as “clustering", for example the k-means algorithm (Mac Queen, “Some Methods for classification and analysis of multivariate observations", Proc Fifth Berkeley Symposium on Math., Stat. And Prob., VoU, pp 281-296, 1967.)
- the descriptor table in Figure 2 has a new column defining in which group the content falls into. Group calculation techniques are well known, using the k-means algorithm, one can easily control the number of groups thus produced.
- the groups are determined by a prior choice of classes (for example: mood (in English: moods), dominant instruments, tempo, etc.) and a ground truth helping to define these classes. They are obtained by applying a learning algorithm to this ground truth.
- the audio documents accessible from the receiver are represented on a screen by graphic identifiers.
- the position of these graphic identifiers that is to say, the spatial coordinates within the graphic page, are obtained from low-level parameters.
- the screen represents a two-dimensional navigation space, a point Pi constituting a graphic identifier representing a sound document Si.
- the coordinates (xi, yi) of a graphic identifier 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 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.
- Low level descriptors being supposed to have a perceptual coherence (the sounds are perceptually close if and only if the values of the low level descriptors are close), and the projection being continuous, the graphic identifiers close on the screen correspond to sounds perceptually close.
- This example in no way excludes representing the collection by a space with more than two dimensions.
- the coordinates ⁇ XJ, y 2 , ... zi ⁇ of a graphic identifier in a multidimensional space allow the user to imagine the type of associated audio document.
- the positions of the graphic identifiers being calculated according to the values of low level parameters, if two identifiers are graphically distant, the values of their low level parameters are very different and therefore, the type of sound content is different.
- the associated audio content is also auditive.
- the browser can analyze the sound documents and determines the main dimensions corresponding to types of audio content, it is then the browser which chooses the number of dimensions of the navigation space.
- the audio documents are grouped according to a “clustering” algorithm, for example the k-means algorithm.
- the graphic identifiers of the elements of the same group have a common characteristic.
- the color of a graphic identifier depends on the group to which the document belongs (for example: blue, red and green).
- a variant described in FIG. 3 consists in giving the graphic identifier a particular form: a circle, a cross or a star.
- An improvement represented in FIG. 3 consists in delimiting the groups using a contour consisting of a closed curved line.
- the navigator calculated three groups A, B and C by differentiating its members by three particular shapes, then represented the contours of each group by a closed curve.
- the graphic identifiers associated with documents in a group appear gathered on the screen.
- identifiers on the screen are very generally not uniform, it appears in the navigation space of groups of identifiers fairly close, these "nebulae” add visual interest in a navigation which links documents sound. There are also isolated identifiers that a curious user may want to listen to.
- groups representing different types of audio content the user "Sees” his collection and can choose audio content by selecting a graphic identifier in the right group.
- the selection of an identifier is carried out by moving a target made up of two perpendicular lines, the target object being at the intersection of the lines. The user moves the target using the arrow keys on the remote control, or a “joy stick”.
- a window at the bottom of the screen displays the title of the audio content being reproduced, if this content is suitable for the user, the user presses "OK" and the content is reproduced. If the window does not contain any title, this means that the target does not target any audio content.
- the user describes the selection and reproduction of a single sound document contained in the collection stored in memory 9.
- the user To start the automatic chaining of several audio contents, the user must first establish a navigation strategy. The user has a good knowledge of the content of his collection thanks to the graphics, it recalls in a certain way nebulae positioned in space, the idea is to establish a path traversing these groups of elements.
- the representation of groups of documents of the same type is not a necessity for navigation, however it provides help for the user who can better imagine how his audio collection is distributed.
- the objective is to use graphic representation as a means of definition for the selection of a strategy and to determine the automatic sequence of documents.
- the first strategy is that of the line segment. This navigation strategy is shown in the drawing in FIG. 4. The user selects a starting document Dd (and therefore a starting point) and an arrival document Df (respectively an ending point), and launches the navigation.
- the browser displays a segment S between these two graphic identifiers and calculates the distances of each identifier the collection with the segment.
- the browser reproduces the audio document associated with the starting document, then reproduces, one after the other, the documents located at a maximum distance from the segment.
- An improvement consists in displaying a mark (the smiling head in FIGS. 4 and 5 for example) moving over the segment from the start point to the end point, and in calculating the distances with the graphic identifiers from this mark.
- the user follows the evolution of navigation and can determine the time remaining before reaching the end point.
- the user enters three parameters: the coordinates of a starting point (denoted Dd in FIG. 4), the coordinates of a point of arrival (denoted Df in FIG.
- the browser automatically positions the square on a graphic identifier.
- the user types on the keys a value between 1 and 99.
- This segment navigation strategy allows you to move from one type of audio document to another, the transition from one document to another being smooth because the documents are graphically close.
- the spiral strategy is represented in FIG. 5, the user selects a starting document Dd (and therefore a starting point), a radius of curvature R and launches navigation.
- the browser displays a spiral whose center is the starting point and whose distance from this identifier increases by the R value each turn.
- the browser calculates the distances of each identifier displayed with the spiral.
- the browser reproduces the audio document associated with the starting document, then reproduces, one after the other, the documents located at a maximum distance from the spiral.
- the browser displays a mark which moves along the spiral as and when reproductions of documents, and, in a graphic window, the number of documents which will be successively reproduced as well as the number d order of the audio document being reproduced.
- the sequence of reproductions stops when the browser can no longer find documents located at the maximum distance, which generally corresponds to the fact that the index of the spiral has left the screen. If the user has placed the starting point in the middle of a group of audio documents, this strategy makes it possible to scan a large part of the group and therefore to reproduce the same type of document for a long time.
- a third strategy involves a random aspect. The user selects a starting document Dd (and therefore a starting point), and a radius of a circle, and launches the navigation. The browser then displays a circle whose center is the starting point. Then, the browser randomly selects the graphic identifiers inside the circumscribed area and reproduces the associated documents. Navigation stops when all documents have been reproduced.
- the browser displays in a graphic window the number of documents that will be successively reproduced as well as the serial number of the audio document being reproduced.
- This third strategy has the same advantages as the second (depending on the starting point) with, in addition, that of avoiding reproducing the documents with always the same sequence.
- the graphic page displays a selection of representations, the user then introduces a criterion for example the genre of the document as defined in its attributes, or the date of creation of the document or the date of recording. , or if they are songs the name of the singer.
