摘要： An apparatus, a method and a system to efficiently manipulate in the compressed domain, spatial and/or temporal scaling of matching pursuit-coded digital signals. These manipulations, referred to as transcoding, may take place at a transcoding proxy located at an origin server, in any intermediary along the transmission path from the origin server to the client device, and/or at the client device. The preferred embodiment focuses on a method to perform rate adaptation and spatio-temporal scaling of a video stream composed of 3-D atoms in order to serve a set of heterogeneous client devices (e.g., a high-end personal computer, a personal digital assistant and a wireless phone). The proposed method applies to 1-D atoms (decomposition of audio signals) and 2-D atoms (image decomposition).

摘要： Techniques for securely and adaptively delivering multimedia content. It is assumed that a set of alternate access units for each time slot is obtained. Then, the encryption stream index of each access unit from the set of alternate access units of the previous time slot are obtained. An encryption stream index is then assigned to each access unit in the set of alternate access units in the current time slot, such that the encryption index increases over time. Thus, the invention overcomes the problem of encrypting a multimedia stream that may have multiple access units for each time slot by selecting the encryption index for each access unit such that the encryption index increases, regardless of which access unit the delivery system (e.g., server) selects for transmission.

摘要： A resource-efficient live streaming system includes a broadcaster and a streaming server. The broadcaster receives a live feed and broadcasts a media stream to the streaming server containing several descriptions of the live feed along with control information. The broadcaster includes a stream thinner that implements a pruning algorithm. If descriptions from different streams are similar enough, one or more of them may be discarded without penalizing the quality of service perceived by the receivers. The streaming server assembles compressed data units into streams according to the control information from the broadcaster. The streaming server may also gather client feedback in order to estimate the status of the transmission channels and forwards the information to the broadcaster. The streaming server builds and streams media information to clients according to user preferences and receiver capabilities.

摘要： Performing adaptive cyber-security analytics including a computer implemented method that includes receiving a report on a network activity. A score responsive to the network activity and to a scoring model is computed at a computer. The score indicates a likelihood of a security violation. The score is validated and the scoring model is automatically updated responsive to results of the validating. The network activity is reported as suspicious in response to the score being within a threshold of a security violation value.
