Abstract: PURPOSE: An apparatus for displaying threshold of visibility receivable in a ground wave digital broadcasting receiver is provided to judge a cause of bad receiving of a digital broadcast by estimating a receiving channel and calculating receivable threshold of visibility, thereby easily coping with the bad receiving. CONSTITUTION: A frame synchronization restoring unit(105) restores frame synchronization from received ground wave digital broadcasting signals. A channel estimator(106) receives the restored frame synchronous signals and estimates a channel from digital broadcasting signals corresponding to the frame synchronous signals, and outputs the estimated channel information. A TOV(Threshold Of Visibility) calculator(107) calculates the receivable TOV from the output channel information according to echo. A TOV signal converter(108) converts the calculated receivable TOV into picture signals. A main control unit(109) transmits the receivable TOV signal to a VSB(Vestigial Side Bands) demodulator(104) to be displayed on a screen.

CONSTITUTION: A bit rate transcoding device includes a target bit rate determining part(110) for determining a target bit rate allocatable to a current frame output from a variable length decoding part. A bit rate-distortion estimating part(120) estimates a distortion amount between the determined target bit rate determined and a bit rate generated by a quantization parameter employed per macro block unit from a difference signal output from a first adder. A target distortion determining part(130) determines an entire target distortion of nth frame currently transcoded from a signal output from the bit rate-distortion estimating part and the output signal from the target bit rate determining part. A quantization parameter determining part(140) determines a quantization parameter for generating distortion near the target distortion output from the target distortion determining part in a bit-rate/distortion curve for the bit rate and the distortion value output from the bit rate-distortion estimating part. Such a determined quantization parameter is output to a quantization par.
