A plurality of bit streams are seamlessly spliced. Separate decoders decode each bit stream. A controller selects the decoded pictures according to a re-encoding range in the vicinity of a splicing point of the bit streams. Pictures presenting a reordering of the streams are excluded in the selection of the decoded pictures. An encoder re-encodes the pictures within the re-encoding range. When it is determined that crossover motion compensation exists between pictures of different streams, the controller changes the motion prediction direction of the problematic picture. The controller changes a motion prediction picture type of a picture which is improperly motion predicted with reference to another stream. A quantization characteristic or motion vectors for the new picture type are generated by the controller. The controller effects the encoding in accordance with a target amount of bits to prevent a breakdown of a buffer and a discontinuation of an amount of data occupancy thereof. A multiplexer multiplexes the original streams with the re-encoded stream to produce a seamless bit stream.

Errors are reduced when tracing PRNS code delay, especially in receivers operating on signals with rather low code frequency (C / A code) under multibeam effect without deterioration or with minimum deterioration of the signal-to-noise ratio. A method of increasing noise immunity during reception of signals from satellite navigational systems and a device for realizing the same includes radio modules, an analog-to-digital converter, a digital correlation device and digital correlators. A discrimination signal is generated with a variable delay of the signal copy with respect to the exact copy. The use of the correcting sequence of gating digital signals makes it possible to eliminate the multipath effect at a delay of the reflected signal larger than 1.5 d and reduces its negative effect starting from a delay value greater than d / 2. In this case, the energy losses compared with a pure mode of the narrow correlator are increased only by 1.76 dB.
