Abstract: A method and computer program product for performing error control of video bitstream data encoded according to a data partition technique used in communication through a wireless channel. The method includes the steps of (a) partitioning video bitstream data into units of information items having certain characteristics and encoding the video bitstream data, (b) calculating a checksum for controlling errors in each partitioned unit of the encoded video bitstream data, (c) constituting a packet, in which each checksum calculated in a the step (b) is added to the encoded video bitstream data and transmitting the packet through a wireless communication channel, and (d) receiving the packet transmitted in the step (c) and checking whether there is an error in each partitioned unit of the encoded video bitstream data through the checksum of each partitioned unit of the encoded video bitstream data. According to the above method, it is possible to effectively detect the errors of the respective partitioned video bitstream data items and to use partial data without abandoning the entire video bitstream packet when errors occur in a specific portion of the video bitstream data by calculating the CRCs of the respective partition regions of the video bitstream data encoded according to a data partition technique.

Abstract: An arrangement for cutting an optical fibre comprises a fibre cutter for cutting the fibre. A motor is provided to operate the cutter. To start a cutting movement, the motor is controlled by a control unit in response to a start signal. The start signal is generated when the fibre is located in the cutter. A detector is connected to the control unit to detect when the fibre snaps off and in response thereto cause the control unit to generate a stop signal to stop the cutting movement. If no fibre snap off is detected, the cutting movement is automatically stopped at a predetermined position of the cutter.

The metal articles are coated with a pulverulent paint based on highly reactive curable epoxy resins which gives, in particular, toxicologically acceptable, heat- and chemicals-resistant, electroinsulating coatings. During this operation, the articles are heated to a temperature above the melting point of the resins, but sufficient for curing the epoxy resins, the resins are applied to the hot surface, which has already been cleaned before the heating, in the form of pulverulent paints by the electrostatic spray process or the whirl sintering (fluidised-bed sintering) process, melted to form a uniform film and cured directly without a further operation. During the application and curing process of the film, cracking phenomena of the organic components of the paint are not observed, in spite of the high temperature of the substrate, so that neither discolouration of the coating nor impairment of the properties occurs. The coatings are distinguished by the absence of pores and the high impact strength and by resistance to water and aggressive liquids.
