    摘要: An apparatus and method for managing a preference channel are provided which can reduce a delay time when a channel change is made between preference channels, by storing a preference channel directly selected by a mobile terminal user in a mobile broadcast system. A mobile terminal receives and demultiplexes multiplexed logical channels on which data streams are transmitted from a service provider through a communication network. Preference channels of the demultiplexed logical channels are dynamically allocated to decoding buffers using stored information. A decoding time at which data of the decoding buffers is accessed and decoded is computed using reference information. A decoding operation is performed at the computed decoding time, and decoded channel-by-channel elementary streams are stored in a memory. The decoded channel-by-channel elementary streams stored in the memory are displayed on a screen of the mobile terminal.

    摘要: An adaptive variable-length coding/decoding method performs an optimal variable-length coding and decoding depending on an intra mode/inter mode condition, quantization step size and a current zigzag scanning position, such that a plurality of variable-length coding tables having different patterns of a regular region and an escape region according to statistical characteristics of the run level data are set. One of the variable-length coding tables is selected according to mode, quantization step size and scanning position, and the orthogonal transform coefficients according to the selected variable-length coding table are variable-length-coded.

    摘要: A multi-scanner scans a signal according to several different patterns. A scanning pattern selector determines which scanning pattern produced the most efficient coding result, for example, for runlength coding, and outputs a coded signal, coded most efficiently, and a selection signal which identifies the scanning pattern found to be most efficient.
