    Abstract: A television camera 12 for picking up a subject and producing an video signal, a plurality of microphones 11L, 11R which are arranged so as to be separate from each other and which collect a vocal sound from the subject filmed by the television camera and output audio signals, an estimating circuit 13 for estimating the position of the sound source on the basis of the audio signals obtained from those microphones, and a coding circuit for encoding the video signal for a specific range of picture area centered the sound source position estimated by the estimating circuit with a larger amount of codes than the video signals for the other picture areas so that the picture area for the specific range may have a higher resolution than the other picture areas construct.
