摘要： An object of the invention is to prevent breakdown of a decoder buffer, and shorten a time required for a multiplexing operation. A multiplexing pattern generator 56 generates a multiplexing pattern signal indicating the order of types of data to be multiplexed. A video remaining size calculator 33 and an audio remaining size calculator 43 calculate, as a remaining size, the size of multiplexable data of an elementary stream. A video packet generator 32 and an audio packet generator 42 generate a multiplex packet containing transmission data of a predetermined size, based on the multiplexing pattern signal and the remaining size. A multiplexer 51 generates a multiplexed stream. The video remaining size calculator 33 and the audio remaining size calculator 43 calculate the remaining size, based on the data size per access unit and the transmission size of transmission data. The video packet generator 32 and the audio packet generator 42 generate a multiplex packet, if the data type indicated by the multiplexing pattern signal shows matching, and the remaining size is equal to or larger than the transmission size.

摘要： A reading control section 40 reproduces information read from a recording medium, and a reproduction-operation section 20 accepts an instruction for a forward skip or a backward skip. Further, a controller 10 makes the skip time for one of the forward skip and the backward skip longer than the skip time for the other, determines the skip time based on one of the instruction for the forward skip and the instruction for the backward skip, and if the instruction for the forward skip and the backward skip is accepted while the information is reproduced, then stops the reproduction, moves the position in which the information is read by the skip time determined by a skip-time determination section 11, and resumes the reproduction after the movement of the reading position is completed.

摘要： A reproduction apparatus, a reproduction method, a reproduction program, and a computer-readable record medium where a reproduction program is stored are provided which are capable of shortening a user's waiting time until the beginning of the part which the user wants to view is reproduced and improving the user's operability.A reading control section 40 reproduces information which it has read from a record medium; a reproduction-operation section 20 accepts either instruction for a forward skip or a backward skip; and a controller 10 makes the skip time for either of the forward skip and the backward skip longer than the skip time for the other, determines the skip time based on either of the instruction for the forward skip and the instruction for the backward skip, and if either instruction for the forward skip or the backward skip is accepted while the information is reproduced, then stops the reproduction, moves the position in which the information is read by the skip time determined by a skip-time determination section 11, and resumes the reproduction after the movement of the reading position is completed.
