The invention relates to a method of monitoring video from a plurality of body mounted video capturing devices, the method comprising: receiving video data from a first body mounted video capturing device of the said plurality; propagating video data received from the said first body mounted video capturing device, or video data derived therefrom, to a closed circuit television (CCTV) monitoring system by way of an input channel thereof; subsequently receiving video data from a second body mounted video capturing device of the said plurality different from the said first body mounted video capturing device; and propagating video data received from the said second body mounted video capturing device, or video data derived therefrom, to the said CCTV monitoring system by way of the same said input channel thereof.

Method of monitoring video

A body-mountable image capture device comprising a device body and a cover slidably mounted onto the device body, the device body comprising a camera, the cover sliding between a first position and a second position such that in the first position the camera is concealed and in the second position the camera is exposed. The body-mountable image capture device comprises activation means operable to initiate the camera when the cover is in the second position and the camera is exposed. The orientation of the camera is adjustable with respect to that of the device body such that the orientation of the camera can be maintained. The orientation of the camera may be automatically adjusted to keep the field of view generally horizontal. The camera may automatically rotate left and right in a horizontal plane responsive to movement of a head mounted sensor to thereby track a user's head movements.

A telephone instrument comprises a mechanism for providing signals for transmission, a mechanism for converting signals received by the instrument into output signals, a switching circuit for selectively establishing and terminating a connection between the instrument and a circuit-switched telephone network and for selectively establishing and terminating a connection between the instrument and a packet-switched communication network. When calling, the instrument signals over the circuit-switched network for a network address for the called instrument and the packet-switched network and establishes a dual connection over the packet-switched network if such a network address is received. When receiving a call, the instrument can terminate the call connection over the circuit-switched network and continue the call by way of the packet-switched network.

The invention concerns in-line monitoring of a communication link between two stations in a frame-based communication network wherein the said two stations employ a compression algorithm for the transmission of frames and a corresponding decompression algorithm for the reception and decompression of the frames, the said algorithms requiring the maintenance at a transmitting station of a compression history in terms of the number of frames transmitted since a datum point and the maintenance of a corresponding compression history at a receiving station in terms of the number of frames received, the frames each including an identification of the compression sequence so that the receiving station can detect mismatch between the compression sequence and the receiving sequence. The monitoring method comprises detecting frames transmitted from one of the stations to the other, detecting whether frames are compressed, decompressing compressed frames and maintaining a compression history corresponding to that maintained by the receiving station.

Monitoring of a communication link utilizing history-based compression

Disclosed are a method and apparatus for collecting network data from a computer network. Control structures are created for groups of data to be collected. The control structures are then associated with corresponding tables for storing the data. Different control structures and extract functions are defined depending upon which data is to be collected, and the form in which the data is to be presented. These control structures and extract functions are then employed to avoid redundant data gathering efforts.
