Embodiment Construction

[0016] Referring to FIG. 1 , a multimedia data exchange system 1 includes a mobile phone 2 connected to a personal computer 4 . A physical data link 6 connects the mobile phone 2 and the personal computer 4 .

[0017] The personal computer 4 is configured to execute an application program for retrieving images from the digital camera. The application uses a specific format, namely EXIF ​​(Exchangeable Image File Format). The EXIF ​​format is neither standardized nor compliant for MMS messages. EXIF is a standard for storing interchangeable information in image files, especially those compressed using JPEG (Joint Photographic Experts Group). In general, most digital cameras now use the EXIF ​​format due to interoperability between imaging devices.

[0018] The mobile phone 2 is adapted to receive or send wireless data communications, such as MMS messages 8 . The transmitter / receiver 10 in the mobile phone 2 functions as a communication control for enabling wireless communic...

Abstract

The telecommunication device (2) is configured to exchange multimedia related data through a data link (6) between the telecommunication device (2) and a destination device (4) adapted to process the data. It comprises - an extracting module (20) configured to extract an embedded multimedia element from a multimedia messaging service (MMS) message, the embedded multimedia element comprising a file format; and - a file format changer (22) configured to change the file format of the embedded multimedia information into an adapted file format to be transmitted to the destination device. In particular, the telecommunication device can be applied to a mobile phone environment.

Description

technical field [0001] The invention relates to format conversion and transmission of multimedia data. Background technique [0002] Today, mobile handsets or phones are capable of supporting multimedia rich features such as text, images, video and sound files. A standard called Multimedia Messaging Service (MMS), as its name implies, enables MMS-capable handsets to send and receive combined messages with multimedia-rich features. [0003] The MMS standard defines the possible content of an MMS message. MMS messages are organized into sets of slides, and each slide, called a multipart, can contain up to three files of different types: text, image, and sound. The purpose of the MMS standard is to ensure the interoperability and exchangeability of multimedia messages. [0004] For example, when exchanging multimedia files between devices, the multimedia content of the received message is separated and stored in the mobile phone. Therefore, image attachments are stored in o...
