Abstract: In this picture signal converting apparatus, digital picture signals compressed in a DVC format are decoded to non-compressed picture signals of a 4:1:1 color component type which are composed of color difference signals and luminance signals. The color difference signals of the 4:1:1 color component type arranged in a matrix are removed on every other row to halve the number of color difference signals in a y direction, and a color difference signal is added to a position between each pair of color difference signals adjacent to each other in an x direction to double the number of color difference signals in the x direction. Therefore, converted color difference signals of a 4:2:0 color component type are produced from the color difference signals. Values of the converted color difference signals are determined according to values of the color difference signals.

Abstract: An automatic gain control circuit of an amplifier 1 having a gain control function is provided with a signal-to-noise detection circuit 2 which detects a signal-to-noise ratio of an output signal and an AGC setting circuit 3 which sets the gain of the amplifier 1. The AGC setting circuit 3 determines the AGC gain according to the level of an input signal and the signal-to-noise ratio detected by the signal-to-noise ratio detection circuit 2. In a region where there is a large AGC gain and where the signal-to-noise ratio is reduced by the AGC circuit, the level of an output signal is increased so as to render the signal-to-noise ratio of the output signal constant. Even if an input electric field is reduced by a fading phenomenon and if there is an increase in the AGC gain, there is prevented a decrease in the signal-to-noise ratio due to an increase in the noise floor stemming from the AGC circuit itself, thereby preventing deterioration of the receiving sensitivity of the automatic gain control circuit.

Abstract: An information recording and reproducing apparatus according to the present invention includes a read-ahead history buffer which is used as a ring buffer. A read-ahead operation is performed, every time a reproduction request is made by a host device, so as to maintain the read-ahead data after the last block for which reproduction has been requested at a predetermined value. Data which has already been requested by the host device and has not been overwritten by the read-ahead operation is treated as history data. As a result, data centered around (i.e., preceding and following) the last block for which the host device has requested reproduction is always secured as cache data.
