    摘要: A computer-implemented method for data recording includes defining a rule, the rule identifying data items exchanged between an originating endpoint and a recipient endpoint over a communication network, having nodes, as target data items for storage by a storage device. The storage device has a communication address. A node of the communication network is configured with the rule and with the communication address of the storage device. The rule causes the node to recognize the target data items while forwarding the data items between the originating and recipient endpoints and to forward respective copies of the recognized target data items to the communication address of the storage device.

    摘要: A non-intrusive signal quality assessment apparatus includes a feature vector calculator that determines parameters representing frames of a signal and extracts a collection of per-frame feature vectors (φ;(n)) representing structural information of the signal from the parameters. A frame selector preferably selects only frames (Ω\with a feature vector (φ;(n)) lying within a predetermined multi-dimensional window (⊖). Means determine a global feature set (ψ) over the collection of feature vectors (φ;(n)) from statistical moments of selected feature vector components ((1̂,01, . . . O11). A quality predictor predicts a signal quality measure (Qj from the global feature set (ψ)).
