Problems solved by technology

However, the ASF approach also has some disadvantages: since each media sample has accompanying metadata packaged with it, the track-based file structure is obsolete, and there is no separate metadata for tracks
Again, this paragraph does not address the issues associated with the live streaming method described above

Embodiment Construction

[0024] The preferred embodiment of the present invention is described in terms of a modified MPEG-4 file format. However, the invention can also be implemented in other streaming applications and formats, such as the QuickTime format.

[0025] Fig. 2 shows a transmission system for multimedia content streaming. The system comprises: an encoder EC, which may also be referred to as an editor, which prepares media content data for transmission, usually from a plurality of media sources MS; a streaming server SS which transmits the encoded multimedia files through the network NW ; and a plurality of clients C receiving the file. The content may come from a recorder, such as a video camera, that records the live presentation, or it may be pre-stored to a storage device, such as videotape, CD, DVD, hard disk, or the like. The content may be, for example, video, audio, still images, and the content may also include data files. The multimedia files from the encoder EC are transmitt...

Abstract

The invention relates to a method for composing a multimedia file comprising meta-data and media-data. The multimedia file is composed such that the file comprises at least one part for file level meta-data common to all media samples of the file and independent segments comprising media-data of a plurality of media samples and meta-data of said media samples.

Description

Background of the invention [0001] The present invention relates to a method and device for processing multimedia data, in particular to the structure of multimedia files for streaming. [0002] Streaming refers to the ability of an application to play synchronized media streams (eg, audio and video streams) on a continuous basis while those streams are being transmitted to a client machine over a data network. A multimedia streaming system includes a streaming server and several clients (players), and the clients access the server through a connection medium (possibly a network connection). A client fetches pre-stored or live multimedia content from a server and plays it back in near real-time while downloading the content. The entire multimedia presentation can be referred to as a movie and can be logically divided into tracks. Each track represents a timed sequence of a single media type (eg, video frames). Within each track, each timing unit is called a media sample. ...
