Method and apparatus for internal and external monitoring of a transportation vehicle

Abstract: An apparatus and method for the monitoring and recording of data stream associated with a transportation vehicle (10), the apparatus comprising at least one capture device (36) for receiving the data stream depicting activities within the transportation vehicle (10); at least one recording device (34) for recording the captured data stream about the activities within the transportation vehicle (10); and a communication device (32) for communicating the recorded data stream to a monitoring station (24, 26).

Digital recording of ip based distributed switching platform

Abstract: A system and method for recording and/or otherwise monitoring IP multimedia sessions. The present invention features a recording and/or monitoring device, referred to hereinafter as 'a recording device' for the purposes of clarity only and without any intention of being limiting. The recording device is a participant in the IP multimedia session, although preferably the recording device only receives data for recording and/or otherwise monitoring the session. Therefore, the IP multimedia session is preferably a multi-user session, such as a 'conference call' for example, even if data is being provided for recording from only one of the participants in the session.

Digital video protection for authenticity verification

Abstract: A method for verifying the authenticity and integrity of an ordered sequence of digital video frames, without having access to the original recording, by embedding therein a respective series of digital signatures based on a secret key, or keys, and on the video content of respective frames. Signatures are camouflaged by embedding in transform coefficients of a transformed representation of the video data in parts of the frame corresponding to motion. If there is sufficient motion to contain all of the signature bits, a supplementary technique embeds in high-texture areas of a frame. A final fall-back is to embed in a pre-defined default zone. A method of predicting when supplementary embedding is needed enables the process to be applied in a single pass allowing real-time operation. Verification is done during decoding by comparing, for identity, embedded signatures with signatures calculated anew using the method employed to embed.

Apparatus and method for multimedia content based manipulation

Abstract: An apparatus and method for multimedia content based manipulation. The method comprises the masking at least one part of the segment of an interaction, said masking can include the hiding, blurring, or alternatively, the enhancing or focusing on a region of interest.

Video streaming parameter optimization and QoS

Abstract: A data streaming system comprises: one or more streaming sources, one or more streaming clients, a network connecting said streaming sources and said clients, and a level of service selector able for each data stream to monitor the network, the respective streaming source and the respective streaming client to control streaming to the respective streaming client to define a level of service of the data stream. For a video stream the level of service may define the frame rate, the resolution, the overall quality or a level of masking used.
