Description

METHOD OF PLAYING A MULTIMEDIA CONTENT TRANSMITTED BY A THIRD- PARTY ON A USER DEVICE
FIELD OF THE INVENTION The invention relates to a user device, a third-party device, and a system comprising a user device, a third-party device and a network, wherein said user device and said third-party device comprise means for communicating via said network. The invention also relates to a method of playing a multimedia content on a user device, and a program comprising instructions for implementing such a method when executed by a processor in a user device. The invention applies to, for example, personal communication devices, such as phones, ADSL modems, set-top-boxes having Web access, or the like.
BACKGROUND OF THE INVENTION US patent application n°20020193094Al describes a method of downloading a phone software product (e.g. games, ring tones, banners, logos, etc.) to a wireless phone on request by a user. This is achieved by dialing a pay-per-call number belonging to a special pay-per- call numbering plan. The call is routed to a wireless telephone service provider and then to a software product content provider. The software product content provider prompts the user to select one or more software products to be downloaded and transfers the selected software product to the wireless telephone service provider which, in turn, transfers the software product to the wireless phone via an SMS gateway. The wireless service provider bills the subscriber at a premium rate for the phone call and transfers at least a portion of the premium rate to the software product content provider as payment for the downloaded software product. One of the objects of the invention is to propose another application in which multimedia content is transmitted to a user device, for example a mobile phone, via a network.
SUMMARY OF THE INVENTION A user device according to the invention is defined in claims 1 to 4. A method of playing a multimedia content on a user device according to the invention is defined in claims 5 to 9. A third-party device according to the invention is defined in claim 10. A system according to the invention is defined in claim 11, and a program according to the invention is defined in claim 12. A user device according to the invention comprises means for communicating via a network, means for booting, means for implementing, during said booting, a protocol for transmitting a multimedia content by a third-party device to said user device via said network, and means for playing, during said booting, a multimedia content transmitted by said third-party device. According to the invention, a protocol for transmitting a multimedia content from a third-party to the user device is automatically implemented each time the user device is booted up without any interaction of the user, which means that the user does not select the transmitted multimedia content. When the user switches on the device, multimedia content is automatically played. This multimedia content is customized by the third-party and can be updated by the third-party, if required. Transmission and playing take place during booting. One advantage of the invention is to allow transmission of a start-up multimedia content (for instance a video introduction, a video logo, an advertisement, etc.) from a third- party to a user device. By way of example the third-party may be the operator of the network, a content provider or the manufacturer of the user device. According to the invention, such a start-up multimedia content is customized by the third-party and can be updated whenever the third-party wishes to do so. Another advantage of the invention is that such a start-up multimedia content is transmitted from the third-party to the user device in such a way that it minimizes the inconvenience for the user. According to the invention, the multimedia content is transmitted and played while the user device is booting. During booting, the user does not have access to the user device. However the communication means of the user device can operate from an early stage of the booting phase (what usually takes time in booting is charging the operating system of the user device; on average this may take 30 seconds or even more for high-end devices). The invention takes advantage of this situation by proposing that a start-up multimedia content is transmitted and played during a period of time when the user would be unable to use his device anyway. If the playback is terminated at the end of the booting process, there will be no inconvenience at all for the user. Transmission from said third-party device to said user device is achieved either by downloading or by streaming. Downloading requires the multimedia content to be stored in a memory in the user device. Streaming has the advantage that such a storage in the user device is not needed. When the downloading mode is used, implementation of the transmission protocol only leads to an effective downloading of multimedia content when the third-party wishes to update the multimedia content to be played by the user device during booting. Advantageously, the multimedia content is compressed in order to lower the network resources required for transmission. For example, it is compressed by using the H263 standard. In a specific embodiment of the invention, when the multimedia content is streamed by the third-party device, playing of the multimedia content is stopped when the booting process is finished in order that the user may start using his device immediately.
BRIEF DESCRIPTION OF THE DRAWINGS These and other aspects of the invention are further described with reference to the following Figures:

DETAILED DESCRIPTION OF THE INVENTION Referring to Figure 1, the system comprises a user device 10, a network 20 and a third-party device 30. The network 20 comprises a telephone network 40 having a Web or a WAP gateway 50. The third-party device 30 is a Web or a WAP server having access to the Web 60. In a first example, the telephone network 40 is of the GPRS or UMTS type, and the user device is a mobile phone having access to the telephone network 40 via a radio link. In a second example, the user device is an ADSL box or a set-top-box connected to the telephone network 40 via a telephone wire. The telephone network 40 is operated by an operator. The third-party may be the operator of the network 40 or any other actor, such as the manufacturer of the user device or a content provider having a business relationship with the operator. Fig.2 is a general block diagram of a method according to the invention of playing a multimedia content on the user device 10. As indicated in Fig.2, this method comprises a step 100 of initiating the booting process of the user device 10. This step 100 is executed when the user switches on the user device. Then three processes PI, P2 and P3 are run in parallel: - the booting process PI (box 102),
- a process P2 of implementing a protocol for transmitting a multimedia content from the third-party device 30 to the user device 10 (box 104),
- a process P3 of playing a multimedia content transmitted by the third-party device 30 (box 106). Dependent on the embodiment considered, there may be a relationship between processes P2 and P3. In Fig.2, this relationship is represented by an arrow 108. When all of the three processes are finished (which is represented in box 109), the user device is available to the user for normal operations. A first embodiment of the method of Fig.2 will now be described in detail with reference to Fig.3. In this first embodiment, the user device 10 has a content memory MEM for storing the content VBOOT to be played during booting. The content playing process P3 plays the content VBOOT stored in the content memory MEM when the user device is switched on. The content transmission process P2 allows replacement of the content to be played during booting. This is achieved by downloading a new content. The new content will be played during the next booting process (that is, the next time the user device is switched on). It is to be noted that downloading takes time so that the process P2 may finish after completion of the booting process PI. In this first embodiment, the process P2 of implementing the content transmission protocol comprises: - a step 110 of transmitting a first request RD1 from said user device 10 to said third-party device 30, the first request RD1 asking whether the third-party device 30 has a content to download to said user device 10,
- a step 112 of transmitting a positive response AO from the third-party device 30 to the user device 10 when the third-party device has a multimedia content to download, - a step 114 of transmitting a second request RD2 from the user device 10 to the third-party device 30, said second request asking for the download of a content,
- a step 116 of downloading a content VD from said third-party device to said user device, and
- a step 118 of storing the downloaded content VD into the content memory MEM. In this first alternative, the content playing process P3 plays the content VMEM (if any) that is stored in the content memory MEM prior to the execution of the process P2. In this first alternative, the content transmission protocol is based on the HTTP transport protocol. By way of example, the first request RDl contains a unique identifier of the current start-up content VBOOT played by the user device 10 during booting. This identifier may be the name of the content file, a URL of the content file, an MD5 key, or the like. This unique identifier is used by the third-party device 30 to decide whether or not a new content is to be downloaded to the user device 10, i.e. whether it has to send a positive response to the user device 10. Upon reception of a positive response AO, the user device 10 sends the second request RD2 asking for the download of multimedia content. This RD2 request points towards a CGI script (CGI stands for Common Gateway Interface) hosted by the third-party device 30. Upon reception of the request RD2 by the third-party device 30, the CGI script is executed which results in the download of the appropriate content. In another embodiment not represented here, sending the second request RD2 upon reception of a positive response AO is not systematic. Based on one or more pre-defined criteria, the user device 10 may decide whether or not it sends the second request RD2. For example, the load of the network, or the size of the available memory may be a criterion. In an alternative embodiment the first request RDl does not contain any identifier of the current start-up content VBOOT stored in the user device. Instead of sending such an identifier, the third-party device keeps a record of the start-up content or contents currently stored in the user devices and decides whether or not to send a new content by looking up its record. A second embodiment of the method of Fig.2 will now be described in detail with reference to Fig.4. In this second embodiment, no start-up content is stored in the user device 10. The start-up content to be played during booting is transmitted from the third-party device 30 to the user device 10 by streaming each time the user device 10 is booted up. The process P2 of implementing the content transmission protocol comprises: - a step 120 of transmitting a request RS from the user device 10 to the third-party device 30, said request asking for the streaming of a content, and - a step 122 of streaming a content from the third-party device 30 to the user device 10 in response to said request. In this second embodiment the content-playing process P3 plays the streamed content as it is received by the user device 10. In this second embodiment, the content transmission protocol is based on the RTSP transport protocol. By way of example, the request RS points towards a known gateway in the network (for example, gateway 50 in Fig.l) and the gateway contains a redirection to a third-party device 30 where the content to be streamed is hosted. Optionally, in this second embodiment, the streaming and playing processes P2 and
P3 are forced to terminate as soon as the booting process PI is finished in order that the user may start using the user device 10. In Fig.4, this forced termination of processes P2 and P3 is represented by an arrow 124. Fig.5 gives a representation of a user device 10. The user device 10 comprises: - a transmission/reception circuit 200 for transmission/reception via the network 20,
- a display 202,
- a user interface 204,
- a content player 206 for playing content,
- a microprocessor arrangement 208 which comprises a working memory 210, a program memory 212 and a processor 214, and
- an interconnection bus 216. In the first embodiment of the invention, the user device 10 also comprises a content memory 220 for storing content, in particular the content that is to be played during booting. As this memory can be omitted in the second alternative embodiment of the invention, it is represented in broken lines . The program memory 212 contains programs for controlling the operation of the user device 10 and, inter alia, a program PU (or a set of programs) for implementing the processes PI, P2 and P3 described above. Fig.6 is a block diagram of a third-party device 30. It comprises: - a memory 300 for storing multimedia contents, in particular a content to be downloaded or streamed to user devices daring their booting in order to be played by said user devices while they are booting,
- transmission/reception means 310 for transmission/reception via the Web,
