Embodiment Construction

[0078] Detailed description of the preferred embodiment

[0079] In order to clearly illustrate the present invention, some examples of content conversion as described below are first provided.

[0080] see figure 1 , picture 100 is the original image before conversion. The picture 101 is a sample video image after content conversion, which can be used for privacy protection. Image 103 adds some fun factors, such as hats and mustaches. In picture 102, a mask is added to hide the face in the original image, which can be used for both privacy protection and entertainment.

[0081] see Figure 2A , in the prior art terminal-based content conversion (TBCT) system, the user terminal 201 has a multimedia capture function and a content conversion function (other functions are not shown). Terminal 201 captures the media source and performs content conversion before transmission over the network to the remote user terminal.

[0082] see Figure 2B , in the network-based content ...

Abstract

Disclosed is a system and method for implementing Network-Based Content Transformation (NBCT) in multimedia communication services. The system includes NBCT Media Server Functions, NBCT Database Function, NBCT Operator Portal Function, NBCT User Portal Function, NBCT Application Server Function, NBCT Charging Function, NBCT Operator Client Function, and NBCT User Client Function. The method comprises steps of creating a NBCT program to implement a content transformation; uploading the NBCT program into a NBCT Database Function (NDF); subscribing a user to a NBCT service; activating the NBCT for the user; and triggering the NBCT and applying to a selected media flow, when the user originates or terminates a multimedia call.

Description

technical field [0001] The present invention relates to a method and system for converting the content of a media stream in a multimedia communication service. More particularly, the present invention relates to a method and system for network-based content transformation (NBCT) functionality for managing and controlling the content of multimedia streams in multimedia communication services. Background technique [0002] Multimedia communication services include user terminals and various network devices. The media stream (e.g. video / audio / text) captured by the user terminal is delivered to the remote user terminal either without any modification, directly, or through some media-processing network device, such as a media gateway or media server, to modify and Match encoding / decoding formats (codes). [0003] However, today there is no network device that changes the content (i.e., visual and audio effects) of the media stream captured by the local user terminal, that is, t...
