摘要： PROBLEM TO BE SOLVED: To prevent an overall video image being displayed on a monitor screen from being modified even if error occurs in a digital video signal.
SOLUTION: An intercom slave unit 1 includes a dividing part 13 for dividing a video signal outputted from a camera 11 into a plurality of segments by video frame and a number-code applying part 14 for generating a segmented video signal by applying a number and a code to each of the divided segments. An intercom master unit 2 includes: an error detecting part 24 for detecting signal error from a received segmented video signal; a frame memory 23 for display for storing a video frame to be displayed on a monitor 11; and a display control part 25 for displaying a video image on the monitor 11 on the basis of information stored in the frame memory 23 for display. The display control part 25 switches the error-detected segment with segment data of a preceding video frame being stored already, generates a video frame with which new and former segment data are integrated, and displays the generated video frame on the monitor 11.

摘要： PROBLEM TO BE SOLVED: To secure excellent call quality by reducing nonlinear distortion generated when expanding a voice signal subjected to irreversible compression such as μ-LawPCM, and to simplify a circuit configuration.
SOLUTION: When a digital voice compression signal which is the call voice of an entrance slave unit 1a and generated by subjecting the call voice to the irreversible compression such as μ-LawPCM by a slave unit voice compression circuit 105 is expanded by a master unit extending circuit 207 of a room master unit 2a, the nonlinear distortion generated in th expansion is reduced by the action of a weighted average filter 208 and the expanded digital voice signal is made smooth. The call voice inputted to the master unit microphone 202 of the room master unit is expanded by a slave unit extending circuit 106 by the same route. The nonlinear distortion generated in the expansion is reduced by the action of a weighted average filter 107 and the expanded digital voice signal is made smooth. The weighted average filter of the entrance slave unit and the weighted average filter of the room master unit each perform weighted average calculation by the power multiplication of the two filters.
