A signal processing apparatus that enables while a significant video signal is not being output, a stream that is decoded to a black picture signal is output along with a base band signal that causes a block picture to be displayed. The signal is reproduced, as an MPEG stream. The MPEG stream is input to a first input terminal of a switch. The MPEG stream is supplied to a black stream generating circuit. A non-signal detector detects a non-signal state of the stream. In a non-signal period, a second input terminal of the switch is selected. A stream generator generates a black stream that causes a black screen to be displayed, which is input to the second input terminal of the switch, and is obtained from a stream output terminal through a switch.

Method and apparatus for performing data conversion between first-format encoded data in which orthogonal transform coefficients are arranged in an order of DC components and AC components from a low spatial frequency order to a high spatial frequency order in each orthogonal transform block when compression encoding which includes orthogonal transform is applied to video data and second-format encoded data in which orthogonal transform coefficients are arranged in an order of DC components and AC components from a low spatial frequency order to a high spatial frequency order in each block assembly member formed of a plurality of orthogonal transform blocks when compression encoding which includes orthogonal transform is applied to video data. The second-format encoded data may be decoded to obtain orthogonal transform coefficients which may be re-arranged from a low spatial frequency order to a high spatial frequency order in each orthogonal transform block of the first format. Such orthogonal transform coefficients may be encoded to form encoded data having the first format.

Odd fields of a high speed television signal within even field intervals of a television signal having a reference frequency are readout from field memories 6, 7 with the time base of the odd fields being expanded. An arithmetical mean of the odd fields thus read out is taken by means of an adder 15 and a divider 16. The signal thus obtained is used as an odd field signal. Further, even fields of the high speed television signal within odd field intervals of the television signal having the reference frequency are read out from field memories 8, 9 with the time base of the even fields being expanded. An arithmetical mean of the even fields thus read out is taken by means of an adder 17 and a divider 18. The signal thus obtained is used as an even field signal.

Information signal reproducing apparatus operates to recover an information signal from record tracks at normal and fast-speed playback modes. Dropouts in the information signal reproduced from the tracks are detected to commence a correction signal interval which ends when a synchronizing signal in the reproduced information signal is detected. A corrected information signal is produced by substituting a correction signal for the reproduced information signal substantially throughout the correction signal interval when the apparatus operates in a fast-speed playback mode.

A solvent recovery treatment method of adsorbing at least two kinds of solvent-gas containing gases different in solvent content concentration, wherein: a rarefied solvent-gas containing gas is first passed through a first adsorbing device; the rarefied gas passed through the first device is switched to be passed through the second adsorbing device after a predetermined time has elapsed while a dense solvent-gas containing gas begins to be passed through the first adsorbing device; the rarefied gas passed through the second device is switched to be passed through a third adsorbing device after the predetermined time while the dense gas passed through the first device is switched to be passed through the second absorbing device, and the first adsorbing device is made to perform regenerating operation.

A time base error corrector comprises a chrominance subcarrier phase corrector whereby the subcarrier phase of a video signal is controlled before being written in the buffer memory in such a way that when the video signal is read from the buffer memory on the basis of the reference video signal, the subcarrier phase of the read video signal may match that of the reference video signal. In the NTSC system, the succeeding line odd/even (O/E) identification is predicted on the basis of a content O/E of the preceding field identification and a content O/E of the preceding field top line identification, and a non-inverted return subcarrier signal is generated when the succeeding top line identification is determined to be odd but an inverted return subcarrier signal RSC is generated when determined to be even. In the system, the succeeding line O/E odd/even and I/N inversion/non-inversion identifications are predicted to generate four different return subcarrier signals. The above control is effective when a VTR is servo-controlled in such a way that the reproduced video signal is written in the buffer memory in advance of the reference video signal in phase.
