  • Television broadcast receiving apparatus
    Patent number: 8339517
    Abstract: A television broadcast receiving apparatus has a demodulating unit including a PLL part synchronizing a phase of an IF signal with a phase of an internally generated carrier signal and outputting an out-of-synchronization flag signal when the IF signal and the carrier signal are in an unsynchronized state, and a muting part muting a sound intermediate frequency signal and outputting a noise signal of a predetermined level when the out-of-synchronization flag signal is outputted from the PLL part. Therefore, even when an IF amplifier of a tuning unit amplifies a noise at the maximum gain when there is no signal, an abnormal sound can be prevented from being outputted from a speaker of a decode and output unit.

Coding map table provider determines a coding map table used in coding of the CBP, based on these CBPs in the neighboring blocks, and provides a coding map table H4 to variable-length code output part. Variable-length coding table provider feeds a variable-length coding table to variable-length code output part. Then the coding target CBP is subjected to variable-length coding, and the resultant is outputted as coded data. This allows information source coding of coding symbols to be performed efficiently according to the coding condition and the property of image.
