摘要:
A system for coding voice signal to optimize bandwidth occupation in a High Speed Packet Switching network while ensuring best voice transmission quality.The voice signal is first encoded using a conventional GSM like RPE/LTP coder providing first sub-frames of coded signal and tagging these first sub-frames as being non-discardable. In addition, a convenient difference between an RPE/LTP provided signal and a corresponding synthesized image is performed (see 36) and is also block encoded into second sub-frames which second sub-frames are tagged as being discardable sub-frames. Said second sub-frames when concatenated to corresponding first sub-frames provide so-called multirate frames. Then, when transmitting said multirate frames over the High Speed packet switching network, dropping discardable tagged data enables solution network congestion situations in any network node and at random with no significant disturbing effect over the voice communication operation.
摘要:
A method and an apparatus for reducing the jitter and end-to-end delay on lines of a packet switching network conveying voice or video digitalized data for one or more connections between a local source and a remote source at a constant bit rate.The method and apparatus of the invention are for use in a voice or video processor of a voice or video processing server of a network node; the method and the apparatus provide a way of controlling the remote traffic rate from the remote source before accessing the processor without using an external clocking such as the network clock.The solution proposed by the invention consists in buffering the remote and local traffics to adapt the remote traffic rate to the local traffic rate, which is supposed having a limited jitter, while sequencing of the access of the buffered data to the processor.
摘要:
Detecting whether an article has been loaded or unloaded for example from a ship by tracking the movements of a transducer such as an RFID tag attached to the article in space, and comparing the tracked movements with a trajectory envelope characterizing the movements associated with a load or unload action, and in the case where the movements of the article are found to comply with the trajectory envelope, registering the article as present in the predetermined volume.

A system of tracking transcontinental shipping containers, which is optimized to conserve the power consumption of tracking devices attached to the containers, is disclosed. The system uses short-range transceiving devices to form a mesh network that includes the tracking devices and a processing device coupled to the shipping vessel, thereby enabling the tracking devices to communicate and update their status without using a long-range or satellite communications adaptors.

The invention provides a file management method and system for managing file retrieval and access. The method operates at the operating system level within a file system of a computer device and allows creating file move links upon detection of a file move request. The file move link associates the file source location with the file target location and is stored within a file move link table of the file system for subsequent file access request. File path to target location is automatically retrieved and file reached transparently for the user.
