Visualization and control techniques for multimedia digital content
First Claim
1. A multimedia preview system in a client/server-based network environment for browsing content of requested multimedia data to be previewed, the content to be displayed on a client terminal for accessing a multimedia server configured to hold the requested multimedia data, the multimedia preview system comprising:
- an interface configured to receive commands indicating a speed at which the multimedia preview system is to browse through at least one of text and an image associated with the requested multimedia data; and
controlling means for controlling visual information for different abstraction levels based on a weighted semantic value of the requested multimedia data and for adapting an abstraction level of a presentation of the at least one of the text and the image, depending on at least markup tags descriptive for and associated with the requested multimedia data and a frequency of the commands and depending upon a combination of the spatial, temporal and semantic layout of said data, such that the abstraction level of the presentation of the at least one of the text and the image is lower when the speed is lower and vice versa, and for changing a layout of the at least one of the text and the image, depending on the speed, the controlling means including a touch-sensitive display configured to navigate through the requested multimedia data to be previewed.

Abstract
A multimedia preview system in a client/server-based network environment for browsing content of requested multimedia data to be previewed includes a processor. The content is displayed on a client terminal for accessing a multimedia server that holds the requested multimedia data. The processor adapts a detail level of a presentation of at least one of text and an image associated with the requested multimedia data, depending on markup tags associated with the multimedia data and a frequency of commands indicating a speed at which the multimedia preview system is to browse through the at least one of the text and the image, such that the detail level of the presentation of the at least one of the text and the image is higher when the speed is lower and vice versa, and changes a layout of the at least one of the text and the image depending on the speed.

6. A method for browsing content of multimedia data to be previewed, the content being displayed on a client terminal for accessing a multimedia server which holds the multimedia data, comprising:
-
downloading the multimedia data from the multimedia server to the client terminal via a network link; receiving and processing, at the multimedia server, commands of representation parameters demanding a change in at least one of a speed of browsing and in an abstraction level of a presentation of at least one of text and an image associated with the multimedia data; decomposing the multimedia data into non-redundant and redundant, less relevant parts for obtaining visual information for different abstraction levels based on a weighted semantic value of the requested multimedia data; adapting the representation parameters by online filtering out a certain amount of the redundant, less relevant parts depending on at least markup tags descriptive for and associated with the multimedia data and a frequency of the commands and depending upon a combination of the spatial, temporal and semantic layout of said data, such that the abstraction level of the presentation of the at least one of the text and the image is lower when the speed of browsing is lower and vice versa; and displaying an adapted version of the multimedia data on the client terminal, wherein a layout of the at least one of the text and the image is changed depending on the speed of browsing, and the commands are based on movements of a pressure across a touch-sensitive display. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A multimedia preview system in a client/server-based network environment for browsing content of requested multimedia data to be previewed, the content to be displayed on a client terminal for accessing a multimedia server configured to hold the requested multimedia data, the multimedia preview system comprising:
-
a processor configured to control visual information for different abstraction levels based on a weighted semantic value of the requested multimedia data and to adapt an abstraction level of a presentation of at least one of text and an image associated with the requested multimedia data, depending on markup tags descriptive for and associated with the requested multimedia data and a frequency of commands and depending upon a combination of the spatial, temporal and semantic layout of said data indicating a speed at which the multimedia preview system is to browse through the at least one of the text and the image, such that the abstraction level of the presentation of the at least one of the text and the image is lower when the speed is lower and vice versa, and to change a layout of the at least one of the text and the image depending on the speed; and a touch-sensitive display configured to navigate through the requested multimedia data to be previewed. - View Dependent Claims (15, 16, 17, 18)
