Abstract: Often hierarchical bi-directionally predicted frame structures are used for encoding a video picture sequence. The frames may consist of interlacing fields. A method for encoding interlaced video, wherein inter-prediction of fields is used and reference lists are assigned to the fields for indicating reference frames or fields, comprises that, if within such reference list a reference to another frame is included, then references to both fields of the other frame are included separately in direct sequence. Further, a temporal level is assigned to each of the frames according to their display order, and for the frames of all except one temporal level the quantization parameter is higher for one type of fields than for the other type of fields.

Abstract: The invention relates to a method for setting an operating parameter in a peripheral IC. In this method, the operating parameter is transmitted from a central IC via a bus connection to the peripheral IC. The method is characterized in that the operating parameter is initially buffered in a preregister in the peripheral IC, and in that the buffered operating parameter is transferred into a working register only if a transfer signal is sent from the central IC via the bus connection. This method has the advantage that, for example in the case of rapidly changing receive conditions in a send/receive unit, adjustment of the send or receive gain setting is very flexible, and it is easy to avoid an incorrect setting due to a detected signal fluctuation. The invention also relates to a device for carrying out said method.

Abstract: Method of adjustment of a receiver of signals transmitted in bursts in a system where the communications are set up within the context of successive frames comprising slots allocatable to the transmitters for their communications with the receivers. The adjustment of at least one characteristic of the receiver allows it to adapt upon the arrival of the bursts, by taking account of at least one reinitialization parameter for a first burst or adjustment parameter computed by a computation unit (4) from the preamble of the burst currently being received. At least one specified adjustment parameter is determined by a computation unit (4), for a new burst of a communication, by taking into account the part of the signal corresponding to the payload of the burst previously received for this communication, if the new is separated from this previously received burst only by a time which is less than a silence threshold value.
