Abstract: A blade (6) for underwater granulation of an extruded polymer, this blade has a plate (60) bounded by a contour including a cutting edge contour (61) having a first end (62) and a second end (63), and an outer contour (64) linking the first end (62) and the second end (63) of the cutting edge contour (61). The outer contour (64) has at least a first bearing portion (65) and a second bearing portion (66), the first bearing portion (65) and the second bearing portion (66) diverging while extending away from the cutting edge contour (61) and configured to be received in a dovetail housing (13).

Abstract: Method for transmission of images comprising: a reception of a source digital image comprising padding lines and data lines, the data lines comprising ancillary data and video data. In order to optimise the use of a transmission channel, the method also comprises: a filtering of padding lines to form sets of data comprising ancillary data and video data; a cutting of the sets into fragments of a maximum fragment length that is a function of a maximum transport packet length; an insertion of at least one image number in each of the fragments, each of the ancillary data and video data being associated with this number; an insertion of fragments into transport packets; and a transmission of the transport packets according to an internet protocol. The invention also relates to a corresponding method for reception.

Abstract: The present invention concerns a transmitter and a receiver and a method thereof for permitting a receiver to reconstruct a stream at a constant bit rate. In particular it concerns a method for transmitting first packets encapsulated in second packets in a transmission system, comprising the steps, at the transmitter, of collecting a predetermined number of the first packets, and triggering transmission of the second packet encapsulating the collected first packets, the second packet comprising a timestamp for each one of the first packets.

Abstract: The present invention relates to a method for processing a stream (10) of multiplexed packets transporting multimedia data according to an MPEG-2 type format, this stream (10) being transmitted at a high bitrate to an intermediary network (12) having low bitrate transmission channels (141, 142, . . . 14n), wherein the high bitrate stream (10) is treated upstream of the intermediary network (12) carrying out the following steps: a step of demultiplexing the high bitrate stream (10) in order to insert packets (1, 2, . . . 44) of data in the low bitrate stream (161, 162, . . . 16n) transmitted by the intermediary channels (141, 142, . . . 14n), a step of alternating, in a synchronized way for set of low bitrate streams (161, 162, . . . 16n), the insertion of packets (1, 2, . . . 44) of data with the insertion of synchronization packets (M1, M2, M3, M4) in these low bitrate streams (161, 162, . . . 16n), so that these low bitrate streams (161, 162, . . .

Abstract: The shifting system comprises a local scrambler (13) on a production site giving the necessary digital data elements to a scrambler (15) shifted to a transmission site. These data elements are inserted, at the image rate, into the compressed television signal transmitted on a low bit rate link to the transmission site. The application relates to systems for the transmission of encrypted television systems.
