AI Technical Summary

Problems solved by technology

Therefore, the size of MMS text messages is limited by the network transmission rate
At present, operators generally limit the capacity of each color text message within 100K, and the maximum does not exceed 300K, so users often encounter similar problems in use: certain multimedia in mobile phones, such as photos taken by built-in cameras, or WAP downloads The capacity of a certain piece of music, or a file with pictures and texts produced by oneself exceeds the above limit, and the mobile phone does not yet have the function of editing various multimedia, so it cannot be sent to friends and relatives for sharing

Embodiment Construction

[0049] At present, the packaging of multimedia information generally adopts the method of SMIL (Synchronized Multimedia Integration Language, Synchronized Multimedia Integration Language). SMIL is a multimedia manipulation language specified by the 3W organization (World Wide Web Consortium). It is a set of well-defined and very simple tags. It is used to specify when, where, and how to play some multimedia data in MMS.

[0050] The core idea of ​​the present invention is to: determine the type of multimedia data contained in the multimedia file and the number of bits of each type of multimedia data; generate a plurality of multimedia information that meets the requirements of the number of bits from the multimedia data; set a custom information; sending the multimedia information in a package.

[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conju...

Abstract

The invention discloses a sending method of multimedia files. The procedures includes: making certain of the multimedia data type comprised by multimedia files and the bit number of various multimedia data; generating a plurality of multimedia information meeting the requirement of the bit number from the multimedia data; setting user-defined information in the multimedia information; packing and sending of the multimedia information. The invention also discloses a multimedia file sending device the bit number of which is not limited. Simultaneously, the invention also provides a receiving method and device of multimedia files without any limitation to bit number. The invention decomposes the multimedia files into a plurality of multimedia information meeting the requirement of the bit number from the multimedia data; the multimedia information is recombined into the style of multimedia file in a receiving terminal, thereby realizing the purpose that the sent multimedia files are not limited by the bit number.

Description

technical field [0001] The invention relates to the field of mobile data communication, in particular to the field of multimedia information, in particular to a sending method, device, receiving method and device for multimedia files with unlimited bits. Background technique [0002] At present, mobile phones have become a must-have communication product for people. At the same time, with the rapid development of mobile communication technology, mobile phones with large-capacity storage space and the ability to expand storage capacity through plug-in cards are becoming more and more popular, integrating various multimedia playback functions. Mobile terminals are more and more favored by users, and the multimedia information (MMS, Multimedia Messaging Service) function that can exchange data through wireless methods has also shown its unprecedented importance. The industry standard of MMS is established by WAP Forum (WAP Forum) and 3GPP (3GPartnership Project: 3G Partnership ...
