Abstract:
A picture-reproducing apparatus for reproducing a moving picture from picture codes recorded in a record medium having sectors, wherein picture codes and an automatic pause trigger bit are recorded in each of said sectors, said picture-reproducing apparatus comprising:a read-in circuit for reading said picture codes and said automatic pause trigger bit from each of said sectors in accordance with a decode sequence; code-inserting circuit for inserting a trigger detection code into said picture codes read by said read-in circuit if said automatic pause trigger bit read by said read-in circuit has an active value; a buffer for temporally storing said picture codes read by said read-in circuit; a decoder for reading said picture codes which have been temporally stored in said buffer, decoding picture data from said picture codes read from said buffer, and setting trigger information of each frame to an active value if said trigger detection code is inserted in the picture codes of respective frame or resetting said trigger information of each frame to an inactive value if said trigger detection code is not inserted in the picture codes of respective frame; a picture memory for temporally storing said picture data and said trigger information while making a relationship between said picture data and said trigger information with respect to a frame; a transfer control circuit for, in accordance with a display sequence, reading said picture data and said trigger information from said picture memory; and a display circuit for displaying a moving picture using said picture data read from said picture memory by said transfer control circuit; wherein when said transfer control circuit detects that said trigger information read from said picture memory has an active value, said transfer control circuit halts reading operation thereof from a succeeding frame, output a halt-requesting signal to said read-in circuit in order to cause said read-in circuit to halt operation thereof, and output said halt-requesting signal to said decoder in order to cause said decoder to halt operation thereof; and wherein when said transfer control circuit halts reading operation thereof, said display circuit displays a frame before the halt in a freeze mode.
