Description

A method of creating a multimedia sequence from a set of selected files

The invention relates to a method for creating a multimedia sequence by aggregating multimedia sub-sequences.

For the purposes of the present invention, a multimedia sub-sequence may consist of one or more multimedia files, in particular of audio, image or video type.

The invention is more particularly in the context of the creation of multimedia sequences on mobile terminals. The sequences created according to the invention can be sent by MMS,

Bluetooth or email and published in personal spaces of users.

On a mobile terminal, the creation of a multimedia sequence from a plurality of multimedia sub-sequences has a first drawback in that it requires the manipulation and processing of a large number of relatively large files (image and / or video files). for example), hardly compatible with the limited capabilities offered by mobile terminals, particularly in terms of display and processing capacity (memory, computing power). Furthermore, the known solutions of the prior art do not allow to create multimedia sequences (video clips ...) with application of a theme or an atmosphere, for example musical, quickly and ergonomically simple, at means of a mobile terminal. This is a second disadvantage. The present invention aims a method of creating a multimedia sequence that does not have the disadvantages of the prior art.

For this purpose, and according to a first aspect, the invention relates to a method for creating a multimedia sequence composed of at least one multimedia sub-sequence selected by means of a communication terminal of a user. This process comprises:

a step of selecting, by means of the communication terminal, at least one predetermined processing code representative of a processing to be applied to the said at least one multimedia sub-sequence;

a step of transmitting from the communication terminal and intended for a remote server terminal adapted for the creation of multimedia sequences, a request for creating the multimedia sequence, this request comprising the processing code and at least one piece of information; representative of said at least one multimedia sub-sequence; and

a step of creation by the remote server terminal of a multimedia sequence by application of a processing, associated with the processing code, to said at least one subsequence, said multimedia sequence thus created being in the form of a multimedia file of predetermined format.

Correlatively, the invention aims a server terminal capable of creating a multimedia sequence, said terminal server comprising: - means for receiving, from a communication terminal of a user, a request for creation of the multimedia sequence said request comprising a processing code and at least one information representative of a multimedia sub-sequence; and

means for creating the multimedia sequence, by applying to said at least one subsequence of a processing associated with the processing code, said multimedia sequence thus created being in the form of a multimedia file of predetermined format.

In general, the invention therefore proposes to create a multimedia sequence from multimedia sub-sequences selected by means of a communication terminal, for example a mobile terminal, the creation of the multimedia sequence itself being performed by a remote server terminal.

Thus, the first disadvantage of the prior art is solved by the fact that the heavy processing is deported to a terminal offering more resources, namely the remote server terminal.

Furthermore, the use of a predetermined processing code, known to the server terminal, makes it possible to standardize the processing operations that are applied to each of the multimedia sub-sequences, a treatment that may correspond, for example, to the application of a predetermined environment which will benefit the final multimedia sequence created by means of the method according to the invention.

In practice, the treatment code can be associated with a predefined "ambiance" otherwise called "theme". This code defines a set of treatments to apply to multimedia sub-sequences, all related to this theme.

For example, a particular code can be associated with the "Thirties" theme. In this case, the treatments applied to the multimedia sub-sequences make it possible to obtain a rendering evoking the era of the 1930s. For example, sepia or black-and-white functions can be used to modify the colors of an image or an image. photography. Similarly, a framing function can be applied specifically to video files and a sound effect can be applied to audio files with the effect of providing a slightly deteriorated sound quality.

The sending of the creation request advantageously makes it possible to create a multimedia sequence almost on the fly and in a very simple way ergonomically, by means of a simple mobile terminal.

The present invention makes it possible to facilitate the creation of multimedia contents shared between different users, via a communications network, and thus to promote the collaborative aspect between these users. users, for whom the creation and exchange of multimedia content is significantly simplified.

The second disadvantage of the prior art introduced in the preamble of this document is solved here. In a particular embodiment, the server terminal according to the invention selects at least one processing function associated with the processing code, according to the format of the multimedia sub-sequence.

The invention enables a media sequencing service provider to define at least one processing function for each subsequence format. Thus, the user of this service does not have to take into account the format of the files mentioned in the creation request, which on the one hand greatly simplifies the use of the service and on the other hand guarantees the obtaining of a multimedia sequence faithful to the theme associated with the selected treatment code. The fact of associating at least one function of processing by format makes it possible to choose the functions best suited to each of the formats, either from the point of view of the quality of treatment, or from the point of view of the optimization of the treatment, for example . By way of example, it is possible to provide a specific image processing for the image files of a particular format.

Moreover, the fact of being able to associate several processing functions with a given sub-sequence format, offers a great flexibility of implementation to the provider of this service.

In a particular embodiment, the server terminal according to the invention comprises means for transmitting the multimedia sequence to at least one terminal.

Thus, the multimedia sequence can be sent by the server to the terminal of a recipient, without the latter needing to do any manipulation. Such a characteristic can be advantageously used in applications in which a The user, at the origin of the creation request, wants a multimedia clip to be automatically delivered to one or more of his contacts, for example on the occasion of end-of-year greetings.

In a variant of the invention, the multimedia sequence created by the remote server terminal is sent only to the terminal at the origin of the creation request.

In another variant, the multimedia sequence is also sent to the terminal of at least one other user.

Thus, the user of the terminal at the origin of the creation of the multimedia sequence can choose a certain number of recipients to whom the multimedia sequence generated by the server must be sent.

For this purpose, it must insert, in the creation request, the identifier of the user concerned.

Note that the invention does not require that the terminals of other users are of the same type as those of the first user, the remote server terminal can send the multimedia sequence to mobile phones but also to other types of terminals, by example of computers.

In one embodiment of the invention, the remote server terminal does not send back to the users the multimedia sequence itself, but a link to this multimedia sequence, dependent on the users' terminals to retrieve the multimedia sequence via the same network or via another network.

In this embodiment, the server terminal according to the invention comprises means for transmitting at least one message containing a link to consult the multimedia sequence, this message being sent to the communication terminal of the user at the origin of the creation request, and / or to a terminal of at least one other user, when an address of such a terminal has been previously entered in the creation request. Sending a link to the multimedia sequence is particularly suitable when the destination terminal has a limited storage capacity.

This embodiment is also very well suited when the multimedia sequence created is to be made available to a plurality of users in a dedicated virtual space, known as a "multimedia movie sharing application".

Advantageously, when the user activates the link to access the multimedia sequence, it is transmitted to him in streaming mode, which has the known effect of minimizing the bandwidth consumption on the network.

Moreover, in this embodiment, only the users actually interested in the multimedia sequence access it, which avoids overloading the bandwidth of the network by sending a multimedia sequence to a user who does not wish to view it.

In one embodiment of the invention, the server terminal according to the invention sends, on the one hand, the multimedia sequence itself to at least one user and, on the other hand, a link to this multimedia sequence to least one user. According to the invention, the remote server terminal creates the multimedia sequence from multimedia sub-sequences. These multimedia sub-sequences can be stored in the communication terminal and sent in the creation request with the processing code. In this particular embodiment of the invention, the information representative of the multimedia sub-sequence included in the request is the multimedia sub-sequence itself.

In one embodiment, the multimedia sub-sequence is stored in a memory space of a remote terminal accessible from the communication terminal of the user via the telecommunications network.

In this embodiment, the user terminal does not send the server, in the request, the multimedia sub-sequences themselves, but a link to these multimedia sub-sequences. In this case, the information representative of the multimedia sub-sequence included in the request is this link (or an address) to this multimedia sub-sequence.

Advantageously, the memory space of the remote terminal is a shared memory space by at least two users identified with this remote terminal.

The present invention makes it possible to facilitate the creation of multimedia content shared between different users via a communications network and thus to promote the collaborative aspect between these users, for whom the creation and exchange of multimedia content is substantially simplified.

In a particular embodiment of the invention, the steps of the creation method performed by the server terminal according to the invention are determined by computer program instructions.

Consequently, the invention also relates to a computer program on an information carrier, this program being capable of being implemented in a server terminal or, more generally, in a computer, in a form comprising instructions for performing the following steps:

receiving, from a communication terminal of a user, a request to create a multimedia sequence, said request comprising a processing code and at least one information representative of at least one multimedia sub-sequence ; and creation of the multimedia sequence, by application to said at least one subsequence of a processing associated with said processing code, the multimedia sequence being in the form of a multimedia file of predetermined format. This program can use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other form desirable shape. The invention also relates to a computer-readable information medium, comprising instructions of a computer program as mentioned above.

The information carrier may be any entity or device capable of storing the program. For example, the medium may comprise storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or a magnetic recording medium, for example a floppy disk or a disk. hard.

On the other hand, the information medium may be a transmissible medium such as an electrical or optical signal, which may be conveyed via an electrical or optical cable, by radio or by other means. The program according to the invention can be downloaded in particular on an Internet type network.

Alternatively, the information carrier may be an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the method in question.

The invention also relates to a signal carrying a request for the creation of a multimedia sequence, this request comprising: for source address, the address of a communication terminal of a user;

for destination address, the address of a remote server terminal; and

at least one piece of information representative of at least one multimedia sub-sequence and a predetermined processing code representative of a process to be applied to the said at least one multimedia sub-sequence.

The advantages and characteristics of the signal according to the invention are identical to those of the creation method mentioned above and will not be repeated here. Other features and advantages of the present invention will emerge from the description given below, with reference to the accompanying drawings which illustrate an embodiment having no limiting character. In the figures:

- Figure 1 schematically shows a system for creating a multimedia sequence comprising a server terminal according to the invention, in a particular embodiment; and

- Figure 2 illustrates, in flowchart form, the main steps of a method of creating a multimedia sequence according to the invention, in a particular embodiment. The present invention will now be described in detail in the context of a composition service of a multimedia sequence from a set of audio files (music), images (photos), videos (films) selected by a user by means of a client application A installed in a read-only memory (ROM) of a mobile terminal 1.

The client application A installed on the mobile terminal 1 is intended to obtain a multimedia sequence from files selected by a user of the mobile terminal 1.

For example, the mobile terminal 1 considered is a third-generation mobile phone compliant with the 3GPP standard UMTS (UMTS: "Universal Mobile Telecommunications System"). The mobile terminal 1 is able to transmit to a remote server terminal 3, multimedia data and able to receive a multimedia sequence S via a telecommunications network 2. The communication means of the mobile terminal 1 are known to those skilled in the art and are not shown in FIG. 1. In the embodiment described here, the mobile terminal 1 stores multimedia sub-sequences in the form of files in a non-volatile memory 10. These files can be of different types, for example, audio , video, image.

In the example described here, are represented two files Fi, F ₂ , respectively of image and sound type. These files can be generated by means of image and sound capture means (camera, microphone) integrated on the mobile terminal 1. In Figure 1, is also shown a processor 11 of the mobile terminal 1 and a random access memory type RAM 12 used by this processor 11 for the execution of the client application A.

The server terminal according to the invention has the conventional hardware architecture of a computer. It comprises in particular a processor 31, a random access memory of the RAM 32 type, a read-only memory of the ROM type

30, this read-only memory constituting a recording medium according to the invention. The server terminal 3 also comprises a conventional communication interface 34.

In this example, the remote server terminal 3 is a multimedia content aggregation server managed by a service provider and capable of aggregating multimedia files, by means of a server application B stored in a read-only memory 13 of the server terminal 3 .

The remote server terminal 3 is able to receive, by means of its communication interface 34, a creation request R issued by the mobile terminal 1, this request R comprising information representative of multimedia sub-sequences (multimedia sub-sequences themselves or links to the multimedia sub-sequences) and a processing code selected by means of the mobile terminal 1.

This request is for source address the address of the mobile terminal 1 on the UMTS network and for the destination address the IP address of the server.

This request is carried on the network 2 by a signal according to the invention not shown.

The remote server terminal 3 is also able to compose, by means of the application B executed by the processor 31, a multimedia sequence S, from these multimedia sub-sequences and the processing code C included in the creation request R .

The remote server terminal 3 comprises storage means constituted in this example by the read-only memory 30 for storing the multimedia sequence. Advantageously, this ROM 30 is shared between at least two users to access the multimedia sequence S.

The remote server terminal 3 is then able to send, via the communication interface 34, via the server application B, the multimedia sequence S to the mobile terminal 1 at the origin of the request R, and / or to other terminals. It can also send a link Ls to this multimedia sequence S to one or more destination terminals (for example remote terminal 4), in place of the multimedia sequence itself S. In the embodiment described here, in the lack of precision in the request R, the multimedia sequence S is returned by default to the mobile terminal 1.

If the user of the mobile terminal 1 wants the multimedia sequence S to be sent to other destination terminals, it specifies their addresses in the creation request R. As an example present, the creation request R contains an address A ₄ of a remote terminal 4 accessible via the telecommunications network 2.

In the embodiment described here, the creation request R includes an option O _p to indicate to the remote server terminal 3 whether to send the multimedia sequence S or a link Ls to this sequence S to the destination terminals.

In practice, the user of the mobile terminal 1 chooses this option O _p by a menu of the client application A. According to the invention, the creation request R issued by the mobile terminal 1 also contains information representative of a multimedia sub-sequence stored on another terminal.

In the example described here, the creation request R comprises a pointer P (Vi) on a video file Vi stored in a user space 50 of a remote terminal 5 connected to the network 2.

In this example, the Vi file is a video file.

Consequently, the creation request R represented in FIG. 1 must be interpreted as a request to create a multimedia sequence S from: the image file Fi and the sound file F ₂ stored in the non-volatile memory 10 of the terminal 1; the video file Vi stored in the user space 50 of the remote terminal 5 including a pointer P (Vi) is included in the request R; and the known processing code C of the remote server terminal 3. This request R indicates that on the one hand the multimedia sequence

S and on the other hand a message M (Ls) having a link L _s to this sequence S must be sent to the mobile terminal 1 and the remote terminal 4 whose address A ₄ is included in the request R, according to the Op option According to the invention, the remote server terminal 3 comprises a database Ti enabling it to identify, from a processing code C and a predefined file type, the processing functions to be applied to the subscribers. multimedia sequences for generating the multimedia sequence S.

In the example described here, the database Ti has three I, W or V field values respectively associated with the image, sound and video type files (I: Image, W: Sound, V: Video). This database Ti indicates that processing functions Hi, H ₂ and H ₃ must be applied to the files of these types.

In the example described here, the treatment code C is associated with the "30s" atmosphere theme and the group of functions associated with this theme includes:

a "black and white" function Hi, which applies specifically to images (type I files, for example of extension: * .jpeg, * .bmp, * .gif) and which has the effect of providing an image in black and white ;

- A "scrambling" function H ₂ , which applies specifically to audio files (type W, for example extension: * .mp3, * .wav) and which has the effect of providing a deteriorated sound quality; and - a "black and white framing" function H ₃ , which applies specifically to videos (type V files, for example of extension * .mpeg, * .avi) and which has the effect of inserting a black frame and white around the image area of the video.

Referring to Figure 2, we will now describe the main steps of the method of creating multimedia sequences in this embodiment.

This method is distributed on the mobile terminal 1 and on the remote server terminal 3. More precisely, the steps E ₁ , E ₂ and E ₃ which will be described later are executed by the mobile terminal 1 and the steps E ₅ , E ₇ , by the remote server terminal 3. During a first selection step E 1, the user of the mobile terminal 1 selects, by means of the aforementioned client application A, two multimedia sub-sequences constituted by the image file Fi, and the sound file F ₂ , both stored in the nonvolatile memory 10 of the mobile terminal 1. During this same step, the selected files Fi and F ₂ are inserted into a creation request R by means of the client application A.

In the example described here, during the first selection step Ei, the user also selects a multimedia sub-sequence constituted by a video file Vi stored in the user space 50 of the remote terminal 5.

This can be done for example by means of a web page. When the user chooses this video file Vi, the remote terminal 5 sends to the mobile terminal 1 a pointer P (Vi) pointing to this sub-sequence Vi. The pointer P (Vi) is inserted by the client application A in the creation request R during this same step.

According to a non-exclusive variant embodiment, it will be noted that the aforementioned client application A also allows the user to select files stored on the multimedia content aggregation server 3, the latter comprising a multimedia file database. shared (not shown). In this case, the client application A is adapted to insert in the creation request R an identifier of each selected file or a hypertext link indicating the location of the selected file on the remote server terminal 3. Such a feature allows not only to provide the user with a large choice of multimedia files for composing a multimedia sequence, without having to store all these files locally, but it also makes it possible to minimize the amount of information sent by the mobile terminal 1 to the remote server terminal 3, for compose this multimedia sequence. During a second selection step E ₂ , the user of the mobile terminal 1 selects, by means of the aforementioned client application A, a predefined processing code C which is inserted in the creation request R with the selected files. Fi, F ₂ and the pointer P (Vi). The processing code C is an identifier associated with a group of predefined processing functions relating to a theme or an atmosphere. A set of processing codes identifying different themes are previously defined at the remote server terminal 3 and associated, in the database Ti already described, processing functions by file type.

In practice, the processing functions are adapted to give multimedia effects to the files.

During this second selection step E ₂ , the user inserts, in the exemplary embodiment described here, the address A ₄ of the remote terminal 4 to which he wishes the remote server terminal 3 to send, on the one hand, the sequence S and, on the other hand, a message M (L ₃ ) comprising a link to this sequence S, in this case a link to a storage space of the server 3 in which the multimedia sequence S is stored.

As mentioned above, the user can choose an option Op to indicate to the remote server terminal 3 if only the multimedia sequence S, only the link Ls, or both the multimedia sequence S and the link L _s must be sent to the destination terminals . This option O _p is inserted in the creation request R, during the same step E ₂ .

During a sending step E ₃ , the mobile terminal 1 sends the creation request R comprising the files Fi, F ₂ , the pointer P (Vi), the processing code C, the address A ₄ and the option O _p selected by the user.

On reception, the remote server terminal 3 processes the creation request R, during a general creation step E ₅ . This general creation step E ₅ comprises substeps which will now be described, namely a substep of identification type E ₅ i, a substep of counting E ₅ 3, a substep of selection of functions E ₅₅ , a processing sub-step E ₅ 7 and an aggregation sub-step E ₅₉ .

During the identification sub-step E ₅ i, the remote server terminal 3 firstly retrieves the video file Vi from which it has received the pointer P (Vi) in the creation request R.

Then, the remote server terminal 3 identifies the type of each file Fi, F ₂ and Vi to be taken into account in the creation of the multimedia sequence S. Taking into account the processing code C and the type I, W, V of each file allows the remote server terminal 3 to automatically select in the database Ti a processing function Hi, H ₂ , H ₃ adapted to each file. The multimedia sub-sequences Fi, F ₂ and Vi are therefore processed according to the theme or the chosen environment, which is identified by the processing code C.

In the example described here, during a substep of counting E ₅₃ , the remote server terminal 3 counts the number of files per type and estimates the duration of the multimedia sequence to be created according to a set of parameters.

Advantageously, taking into account the number of files per type allows the remote server terminal 3 to automatically select a processing function adapted to the number of files to be processed for each type of file.

For example, in the case where the number of files of the same type to be processed is high, a treatment function optimized in computing time will be selected.

This substep of counting E ₅₃ is optional. However, it may be advantageous for certain types of multimedia effects. It is for example the case of creating a photo slideshow from a set of image files (* .jpeg) and a sound file (* .mp3). In this case, it is assumed that the multimedia effect consists in adjusting the duration of a musical piece contained in the sound file, taking into account the number of photos to be assembled, the duration of display of each photo and the interval time between the display of two successive photos, so that the photos scroll for the duration of the musical piece.

In a particular embodiment, the database Ti may comprise several functions H, associated with the same type of file I, W, V. In this case, the remote server terminal 3 chooses one or more of these functions H, for process files of this type. In particular, two functions can be applied successively. A function can also be applied randomly.

In the present example, the remote server terminal 3 determines that it must process the image file Fi ₇ the sound file F ₂ , and the video file Vi according to the theme "Years 30" indicated by the treatment code C.

During a selection sub-step E ₅₅ , the remote server terminal 3 selects for each type I, W, V of file, a processing function Hi, H ₂ , H ₃ adapted to the type and possibly to the number of files. this type.

In this example, the remote server terminal 3 selects:

the "black and white" function Hi for processing the image file Fi;

the "scrambling" function H ₂ for processing the audio file F ₂ ; and the "black and white framing" function H ₃ for processing the video file Vi.

During a processing sub-step E ₅₇ , the remote server terminal 3 applies the selected functions Hi, H ₂ , H ₃ during the selection sub-step E ₅₅ to the corresponding files Fi, F ₂ , Vi.

Advantageously, whatever the type (audio, video, image) of the multimedia files selected by the user, the terminal remote server 3 selects and automatically applies a processing function adapted to the type of each file and possibly to the number of files to be processed for each type.

During the aggregation sub-step E ₅₉ , the remote server terminal 3 generates a multimedia sequence S by aggregating the files obtained at the end of the processing sub-step E ₅₇ .

Once the multimedia sequence S has been generated, the remote server terminal 3 determines, according to the option O _p received from the creation request R, whether it must send to the destination terminals 1 and 4 the multimedia sequence S, a message M (L ₅ ) having a link Ls to a storage space having this sequence S or both.

In the example described here, the option O _p indicates to the remote server terminal 3 that it must send both, that is to say the multimedia sequence S and the message M (L _S ). Accordingly, during a sending step E ₇ , the remote server terminal 3 sends the multimedia sequence S and the message M (L ₃ ) to the mobile terminal 1 and to the remote terminal 4 via the telecommunications network 2.

Prior to the sending step E7, the remote server terminal 3 stores the sequence S in a storage area of the read-only memory 30, the link L ₃ pointing to this storage area.

Of course, the multimedia sequence S can be stored in a personal space of the user of the mobile terminal 1 or the remote terminal 4. In this way, the multimedia sequence S can be made available to the users authorized to consult this personal space (for example, a blog). This is particularly advantageous for sharing multimedia sequences composed from files generated locally at a mobile terminal.
