    摘要: The present invention relates to a physical layer signalling in a digital broadcast network. In particular, for a digital broadcast network supporting a configuration with a plurality of physical layer pipes, a type indicator is signalled on physical layer for a pipe, the type indicator indicates the format of the input stream which may specify a transport stream, a generic stream or an IP stream. In addition, per physical layer pipe application of header and/or content compression to the user packet headers of the input stream is signalled. Another physical layer parameters are advantageously provided or extended in order to increase the flexibility and efficiency of the layer 1 signalling.

    摘要: A mining apparatus includes two tool drums, which are arranged rotatably side by side in twin arrangement on a drum carrier and which are respectively provided with a plurality of tool carriers which support cutting tools arranged over the periphery of the tool drums and which can be rotatingly driven and the shaft axes of which run substantially transversely to the drum axle. The shaft axes of the tool carriers of the first tool drum span a first conical surface about the drum axis and the shaft axes of the tool carriers of the second tool drum span a second conical surface about the drum axis, where the conical surfaces are open to opposite sides and are preferably oriented such that they are mutually inclined in an O-arrangement.

    摘要: An apparatus for the milling cutting of rock, minerals or other hard materials has a tool drum which is rotatably mounted on a drum carrier about a drum axis and on the peripheral shell surface of which are disposed, in distributed arrangement, a plurality of tool carriers, which carry cutting tools and can be rotatingly driven, where their shaft axes run transversely to the drum axis. A first group of tool carriers and a second group of tool carriers are provided, where the rotational direction of the first group is counter to the rotational direction of the second group, and the shaft axes of the tool carriers of the first group and of the second group are oriented at different setting angles relative to the radial direction of the tool drum.

    摘要: The present invention relates to a subchannel structure within a main service channel for transmitting data of at least one application in a digital audio broadcasting system, such as DAB or DRM. Further methods for transmitting and receiving application data using the subchannel structure, as well as a corresponding broadcasting station and receiving terminal are provided. To increase the number of data packets of which undamaged data can be derived under identical reception conditions in a backward-compatible way the present invention provides a subchannel structure comprising a predetermined number of data packets and a predetermined number of error control packets, wherein each of the error control packets comprises an error control code field the data of which is generated based on at least a part of the packet data field and/or at least a part of the packet header of the data packets and a CRC field preceding the error control code field for protecting same.
