Description

METHOD AND SYSTEM FOR PROVIDING WIRE / WIRELESS VOD STREAMING PACKAGING SERVICE}

The present invention relates to an apparatus and a method for providing a wired / wireless VOD streaming packaging service. More specifically, the present invention relates to a streaming packaging including a function of adding encoding profile information of individual video contents to be packaged into a tail-encoded output video file format. It relates to a service providing method.

Recently, with the development of information and communication technology and computers, the Internet has been rapidly developed, and not only texts and pictures but also videos are provided through the Internet.

In the related art, in order to use a moving image file through a network, a download time of a large multimedia file has been inconvenient because the moving image file must be downloaded from the server and then played back.

Therefore, in recent years, the VOD service, which is an interactive video service, enables subscribers to immediately select and watch a desired program at a desired time. The VOD service enables real-time playback even with a certain amount of data. If a user selects one content, the VOD service downloads a certain amount of data from the server and plays it in real time, while simultaneously displaying the next predetermined amount of data. It is a service that can be played in real time without having to download a moving picture file by repeating the download and playback.

A value representing the attribute of the content.

The reason for referring to these encoding profile values is that the encoding profile values of the individual contents must be the same in order to package the respective video contents into one for the streaming packaging service. Therefore, if profiles of individual contents to be packaged are different from each other, the contents should be converted and packaged to have the same profile value.

Accordingly, in the related art, video raw data is encoded in order to produce individual content for a streaming packaging service. The generated video file and encoding option profile information of the video file are separately stored and separately transmitted to the VOD streaming server. There was discomfort.

The technical problem of the present invention is to add the profile information in the form of a tail (tail) to the file format that is produced as an output when producing the individual video content to solve the above-mentioned, in order to package the individual content when providing a streaming package service The present invention relates to a method for providing a streaming packaging service to solve the inconvenience of separately storing each encoding profile information and transmitting the encoding profile information separately to a server.
