Abstract: A telecommunications transmission system adapted for the transmission of MPEG-2 data streams with a variable bit rate includes an encoder and decoder. The encoder includes a system layer multiplexer adapted to empty a video encoder buffer by reading data blocks therefrom, at a bit rate which is constant within a block. The encoder provides a way of realising VBR in an MPEG-2 system layer multiplexer which has been adapted for ATM, and represents a particularly simple implementation of a VBR MPEG-2 encoder having good jitter control. The encoder eliminates the need for a special "cell shaping" function in order to fulfil a traffic contract. To recover bit timing in the MPEG-2 decoder, data is buffered in a reception buffer. By continuously reading the deviation of the buffer level, i.e. the level to which the buffer is filled with data, from its nominal value, in this buffer, the deviation of the emptying rate of the buffer, from the nominal bit rate, can be controlled with a phase lock loop (PLL), or similar arrangement.

Abstract: Particles conferring physical and/or mechanical properties are added or formed in the bath, during laser irradiation. They are mixed in. Laser irradiation bonds the particles into hardened resin, and/or to the resin and/or to each other.  Preferred features: The particles are mixed in and distributed, in solid and/or liquid and/or gaseous form. Particles in liquid or solid form are provided with surface gas bubbles, or bubbles within them. Particles are converted into gaseous form by the laser irradiation. The particles are introduced as nano-materials in the form of nano-metals or nano-fluids. Preferably-liquid particles are coated with a parting layer, preventing dissolution into the bath. A coating fosters bonding of particles with resin or to each other. Particles are encased at high concentration by a layer capable of sintering or agglomeration by laser, by addition to the bath. For uniform particle distribution, ultrasound irradiation is carried out. The particles are surface-activated, before introduction. Plastic particles are treated in this way, by plasma. Metallic particles or compounds are treated chemically, for activation. They are activated by nano materials, especially in fluid form. They are added selectively. Addition is analogous to inkjet or screen printing methods. Particles with magnetic characteristics are added. They are especially aligned electromagnetically in the unhardened state of the resin. Two-shot irradiations are carried out, the first shot being less intense than the second. The object is recyclable by grinding, using a liquid nitrogen treatment, followed by screening of resin and particles.
