At least two turbo decoding apparatuses are used in a receiver for concatenated convolutional coding transmissions imbedded in 8-VSB digital television signals. The sensor means comprises in this case at least one sensor arrangement for sensing components of the light from the light source that are directed into a region surrounding an entering face of an optical component of the projection system. This resolution comprises determining the location of the remote node based on a desired application or service, and then determining the IB parameters needed to communicate with the remote node. Another message directed to another specified client application cache is generated for each rule that matches a first received message at a first client application cache.
