  • Patent number: 9306996
    Abstract: A streaming connection management method and system are provided. In the streaming connection management method, a streaming source establishes a plurality of connecting requests through a first relay server, and the first relay server provides first streaming data. A number of connections established with the first relay server is determined. When the number of the connections established with the first relay server is greater than or equal to a first relay threshold of the first relay server, a data balance method is executed to obtain a second relay threshold. The first relay server is adjusted to provide a second streaming data, in which a pixel value of the first streaming data is greater than a pixel value of the second streaming data.

  • Patent number: 7499055
    Abstract: The present invention employs the notion of a Chinese writing brush in moving a geometric figure to produce a style of calligraphy, where the area of the geometric figure is large or small, then the strokes of a character are thick or thin. Hence the purpose is that the variance of the strokes of a character can be achieved using the present invention. The present invention only decides a moving path for the strokes of a character and the size of a geometric figure at starting points and end points, and then moves the geometric figure along the moving path, where the area the geometric figure passes is the style of calligraphy.

  • Patent number: 7366899
    Abstract: An architecture of multilayered DRM protection structure for multimedia service and the method of forming the same are provided. The architecture comprises a multilayered DRM encryption structure and a DRM decryption structure. The inputted multimedia service is decomposed and encrypted into an encrypted multimedia service stream through a multimedia service decomposer and a multimedia DRM organizer. The encrypted stream is decrypted by a DRM composer from top layer to bottom layer. A full or partial multimedia service is then presented. For a multimedia service application, this enhances the DRM protection by increasing the complexity of multimedia encryption for a multimedia service application. It also provides the variety for the multimedia service application via different compositions of multimedia objects. The DRM protection structure is embedded into each layer of multimedia services and objects and can be set up different levels of DRM protection.
