A broadcasting reception apparatus includes a display unit for presenting a display showing a plurality of channels, with which the user can recognize whether decoding software programs for decoding program signals being currently broadcast via each channel are held in a library buffer, or not, thereby making possible pleasant zapping.

Broadcasting reception apparatus and data broadcasting method

A coding method comprises a hierarchical coding step of performing hierarchical coding for data to be coded to generate first and second code sequences, each comprising a plurality of code layers; a storage control step of storing the first and second code sequences in a storage region of a code storage means having successive addresses, respectively from opposed ends of the storage region, according to priority given to the code layers; and a priority judge step of storing a code layer in either of the first and second code sequences, which code layer has the highest priority at present, prior to the other code sequence, when an overlap occurs in the storage control step. Therefore, the code layers are stored in the storage element having limited capacity with high efficiency, whereby the utilization efficiency of the storage capacity is improved.

Coding method, coding apparatus, wavelet transform apparatus, and

A real-time image recording/reproducing apparatus which receives an image signal and compresses the image signal so as to produce compressed data which the apparatus stores. The apparatus judges whether or not sufficient empty space for storing the compressed data exists. The apparatus stores the compressed data if sufficient empty space exists, or allocates required empty space by releasing oldest data among the stored compressed data if sufficient empty space does not exist. The apparatus receives a replay instruction and expands the compressed data in response to the replay instruction so as to produce image data, and outputs the image data.
