摘要： System and method for performing a splice operation on an encrypted or unencrypted MPEG-2 transport stream. A splice trigger is received at a pre-conditioning encoder. In response, the encoder generates, e.g., an SCTE-35 cue message that is intended to be received by a splicer. Also in response to the splice trigger, the encoder encodes/conditions a network feed such that a decoder buffer delay reaches a predefined value at a video frame of the network feed that corresponds to a splice point indicated by the SCTE-35 cue message. The network feed may then be encrypted in a known fashion. At the splicer, another feed is switched into the stream at the splice point, wherein the another feed is encoded such that a decoder buffer delay at a video frame of the another feed corresponding to the splice point is the same as the predefined value. The predefined value is defined as DTS−STC, where DTS is a Decoding Time Stamp and STC is a System Time Clock. The pre-conditioning encoder generates around the splice point audio PES packets that contain a single aligned audio frame.

摘要： A method is described for compressing and/or transporting and/or decompressing a digital signal. The most significant bits of a sample of the digital signal are compressed and transported as a compressed transport sample. Methods are used to improve the compression and transport as hybrid DPCM and a dynamic shift of clip range of prediction errors. For every sample, not only a compressed transport sample but also a residual transport sample is transmitted. The residual transport sample is either equal to the least significant bits of the sample or equal to a substitution value which is a function of the clipping error from the compression of the most significant bits of the said sample. Apparatuses are described for compression and/or transport and/or decompression of a digitized television IF signal according to the method.
