Title: Method for signaling monitoring in No.7 signaling network
Inventor: BAE CHEOL MIN
IPC: H04Q1/20
Filed: 2000-12-19
Abstract: PURPOSE: A signal monitoring method in No.7 signaling network is provided to monitor a signal message without a signal monitoring device by copying a signal message satisfying a pre-set signal monitoring condition, transmitting it to an operating system and monitoring the signal message by the operating system. CONSTITUTION: After a signal monitoring condition is set, a signal message processor for processing a signal message determines whether a corresponding signal message satisfies the signal monitoring condition on the basis of a routing table contained in the received signal message(S10). If the received signal message does not satisfy the signal monitoring condition, the signal message processor processes the corresponding signal message according to a processing procedure(S12). If the received signal message satisfies the signal monitoring condition, the signal message processor copies the corresponding signal message, processes the original version of the signal message according to the signal message processing procedure and transmits the copy version to an operating system by using an IPC(Inter Processor Communication)(S14). Upon receiving the signal message from the signal message processor, the operating system stores the signal message in a certain memory area, searches the signal message stored in the memory area in response to a request of a system operator and outputs the searching result(S14).

IPC: H04N1/387
Filed: 2001-01-19
Abstract: PURPOSE: A method is provided to insert a visual element into an encoded bit stream with minimal decoding of the encoded bit stream. CONSTITUTION: A method comprises the steps of receiving an encoded bit stream containing a picture, partially decoding a copy of the bit stream, determining if a segment of the picture in the bit stream is affected by the insertion of the visual element, re-encoding the segment if the segment is affected by the insertion of the visual element, and outputting the re-encoded bit stream. The encoded and re-encoded bit streams are MPEG-encoded bit streams. The re-encoded bit stream is output using a bit rate control process that randomly selects an initial processing point within the re-encoded bit stream, re-quantizes the re-encoded bit stream using a modified quantization table, and/or utilizes a slice-level stopping criteria for selectively starting or ending bit rate control.
