Abstract:
A transmission signal which is an article of manufacture, produced by encoding a wideband digital signal of a specific sampling frequency F.sub.s in an encoder, the transmission signal comprising consecutive frames, each frame comprising a plurality of information packets (IP), each information packet being composed of N bits, N being larger than 1, and a frame comprising at least a first frame portion including synchronization information, characterized in that:the number B of information packets in one frame has a relation to a value P, such that,if P in the formulaP=(BR.times.n.sub.s)/(N.times.F.sub.s)is an integer, where BR is the bit rate of the transmission signal and n.sub.s is the number of samples of the wideband digital signal whose corresponding information in the transmission signal is included in one frame of the transmission signal, the number B of information packets in one frame is P, or that,if P is not an integer, the number B of information packets in a number of frames is P', where P' is the next lower integer following P, and the number of information packets in the other frames is equal to P'+1 so as to exactly comply with the requirement that the average frame rate of the transmission signal is substantially equal to F.sub.s /n.sub.s.
