Problems solved by technology

This in turn leads to the fact that, even though the media can actually be rendered, the user perceived quality when rendering transcoded media is far from perfect and often (far) worse than when rendering the original non-transcoded media

Embodiment Construction

[0038] Throughout the drawings, the same reference numerals will be used for corresponding or similar elements.

[0039] The present invention relates to the management of media and multimedia content, and in particular to processing such media and multimedia content in order to mitigate and eliminate media degradation caused by transcoding the content and to improve user perceived quality when rendering transcoded media.

[0040] The present invention is a supplement to or used in conjunction with existing media transcoding schemes and systems, so as to compensate for the inevitable changes and degradation of media caused by such transcoding schemes and systems during the transcoding process.

[0041] As mentioned in the background section, media transcoding changes the properties of the media by transcoding the media between different encoding standards and media formats suitable for different rendering devices and user terminals. Such an encoding standard typically lacks th...

Abstract

The invention relates to media management and combats media degradations arising when transcoding the media. The invention solves this by—generating processing hints based on the media transcoding. The hints are employed for controlling a post-transcoding processing of the transcoded media content in connection with rendering the media. The hints and this controlled processing increases the user-perceived quality when rendering the media by mitigating the media degradations caused by the transcoding. The processing hints could specify how the actual transcoding was performed by including values of the employed transcoding parameters or information of the alterations to the media caused by transcoding. Furthermore, instructions or commands for appropriate post-transcoding processing could also be processing hints according to the invention.

Description

technical field [0001] The present invention relates generally to the management of media content and, more particularly, to media content processing to mitigate media degradation caused by transcoding the media. Background technique [0002] The presentation and presentation of images, graphics, video and other types of media, multimedia content on data processing systems and user terminals such as computers and in particular on mobile terminals has increased tremendously in recent years. This increase in media presentation and the use of a large number of different data presentation devices and terminals often requires the ability to process media content in order to adapt the content to a particular presentation device. For example, the first wireless communication unit generates images in a first image format and in accordance with a first image standard that are compatible with the capabilities of the communication unit. The generated image is then wirelessly sent to a...
