  Furthermore, in this embodiment, the image reproduction side control unit 9 has a fixed value for the decompression time of the compressed image data. When the image reproduction side control unit 9 cannot obtain information about the decompression time required for decompressing the compressed image data in the previous operation from the image decompression unit 16, the fixed value of the decompression time, The reception prohibition time is obtained by adding the compression time required for the compression of the image data in the previous operation.

  Thereby, even when the information of the decompression time in the previous operation cannot be acquired from the image decompression unit 16, the reception prohibition time can be set.

  Next, the operation of this embodiment will be described.

  In the present embodiment, for the sake of convenience, the operation has already been performed immediately before the main operation performed by the operator, and information on the decompression time required for decompressing the compressed image data in the previous operation is controlled by the image reproduction side control. It is assumed that it is properly acquired on the part 9 side.

  As shown in FIG. 2, in the present embodiment, when the operator performs this operation via the input means, the apparatus that has performed this operation is the image reproduction device 3 as shown in step 1 (ST1). If it is the image reproduction device 3, the process proceeds to step 3 (ST3), and if it is the image display device 4, the process proceeds to step 2 (ST2).

  In step 2 (ST2), the operation information (electric operation signal) of the main operation input by the input means 18 and 21 is transmitted from the image display device 4 side to the image reproduction device 3 side via the digital transfer bus 2. After that, the process proceeds to step 3 (ST3).

  Next, in step 3 (ST3), the image reproduction side control unit 9 determines whether or not this operation is an operation accompanied by reproduction of pay image information such as pay broadcast, and when reproduction is involved, This operation is determined as an operation to be controlled, and the process proceeds to step 5 (ST5). If reproduction is not performed, the process proceeds to step 4 (ST4).

  In step 4 (ST4), it is determined whether or not this operation is accompanied by a transition of the menu screen. If the operation is accompanied by a transition, this operation is determined to be a control target operation and the process proceeds to step 5 (ST5). If it is not accompanied, this operation is determined as a non-control target operation, and this operation is accepted as it is and reflected in the reproduction and display of the image.

  In step 5 (ST5), it is determined whether or not the reception prohibition time has elapsed between the previous operation and the main operation. If not, the operation is invalidated. This operation is accepted and reflected in the reproduction and display of the image.

  Therefore, in the present embodiment, the control target operation can be prevented from being erroneously performed on an important operation by reflecting the control target operation on reproduction and display only after the reception prohibition time has elapsed.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
