Title: Method and system for limiting quality of service of data transmission
Inventor: VIRTANEN KARI
IPC: H04L12/56
Filed: 1999-12-15
Abstract: A method of limiting the quality of service of data transmission in a wireless telecommunications system, in which the quality of service of data transmission is defined by means of quality of service parameters. Subscriber-specific maximum values are defined for the quality of service parameters and stored in a database comprising subscriber data. When the terminal requests connection establishment defined with quality of service parameters, the subscriber-specific maximum values are checked in the database and they are compared with the quality of service parameters requested by the terminal. Depending on whether the quality of service parameters requested by the terminal are within the limits defined by the maximum values of the parameters or whether at least one quality of service parameter requested by the terminal exceeds the maximum value defined for said parameter, either a connection is established or connection establishment is rejected.

Title: Encoding/decoding apparatus and method for orientation interpolator node data
Inventor: KIM DO-KYOON
IPC: H04N19/00
Filed: 2001-10-19
Abstract: An encoding/decoding apparatus and method for an orientation interpolator node are provided. The encoding/decoding apparatus for an orientation interpolator node, which provides rotational information of an object in a 3-dimensional space, is formed of "key information" which indicates a time when a rotational movement occurs and "key value information" which indicates a rotational posture corresponding to the time. A predictive coding apparatus is used in the encoding process for compressing the information of the key and key value information. Therefore, in encoding an input orientation interpolator node in an information compression method of a predictive encoding method, the efficiency of encoding is improved and an reverse rotation due to an encoding error from lossy coding can be corrected.
