Embodiment Construction

[0028] Generally, Motion Joint Photographic Experts Group (MJPEG) adopts JPEG, ie still image compression, for moving image compression. Each MJPEG frame is compressed according to JPEG. JPEG, an international standard for the compression of continuous-tone still images defined by the Consultative Committee for International Telegraph and Telephone (CCITT) and the International Organization for Standardization (ISO), specifies a method for compressing images such as grayscale or color images other than binary images A must for almost any flat still image.

[0029] MJPEG compresses individual frames such as single frames regardless of previous and subsequent frames, and also compresses moving image playback information, thereby obtaining a higher compression ratio than MPEG. In addition, MJPEG can control the image quality by adjusting the compression ratio during compression, and can achieve fast compression due to a small calculation amount.

[0030] According to the presen...

Abstract

The present invention discloses a moving picture streaming file, method and system for a moving picture streaming service of a mobile communication terminal. A wireless moving picture streaming file is generated by adding audio payload data to an MJPEG moving picture file, and adding payload headers for controlling streaming of each payload data. When the mobile communication terminal requests the streaming service, a server provides the previously-generated wireless moving picture streaming file to the mobile communication terminal. The mobile communication terminal plays the payload data by using payload header information of the wireless moving picture streaming file. The mobile communication terminal controls transmission of the payload data consisting of a plurality of segments by using segment headers. Therefore, the wireless moving picture streaming service can be rapidly reliably provided to the mobile communication terminal by using the MJPEG and a user datagram protocol.

Description

1. Field of invention [0001] The invention relates to a method and a system for providing moving picture data flow service through mobile communication terminal, and the file format of moving picture data flow used for the service. 2. Background technology [0002] Generally, streaming is a multimedia data transmission method that reads, transmits, and plays data in real time on the Internet. Data streaming technology allows users to watch and listen to large-capacity video or audio data in real time on the Internet without downloading the data to a PC. [0003] Technologies for implementing moving picture data streaming are roughly divided into moving picture compression algorithms and network protocols. Typical moving picture compression algorithms include Moving Picture Experts Group (MPEG) and H.26x, and typical network protocols include Real-time Transport Protocol (RTP) and Real-time Control Protocol (RTCP). [0004] MPEG and H.26x are hybrid compression methods of m...
