摘要： PROBLEM TO BE SOLVED: To provide a clock generating circuit for realizing phase matching between an internal clock and an external clock received externally and phase matching between the internal clock and a frame signal received externally within a range of permissible performance deterioration with a reduced circuit scale. SOLUTION: This invention provides the clock generating circuit within a range of permissible performance deterioration with a reduced circuit scale wherein a signal processing apparatus shares only a phase comparator or the phase comparator and an LPF by utilizing a fact that the phase matching between the external clock and the internal clock and the phase matching between the frame signal and the internal clock are not performed at the same time.

摘要： PURPOSE:To eliminate a time difference between audio data and video data on a tape and an external output stage by increasing the capacity of picture memories for performing the rearrangement of video data for a delay time between the audio data and the video data. CONSTITUTION:At the time of a recording, inputted video data are processed by a filtering, etc., in an input processing circuit 3 and the rearrangement of data for one page are performed by using a picture memory 4 having a capacity for one page and a picture memory 5 having a capacity for +alpha. Since the rearrangement of data for one frame are performed with picture memories 4, 5 having the capacity for one and +alpha page, the video data can be delayed for +alpha even though a read out is performed by being advanced to a write-in to picture memories 4, 5. Rearranged video data are compressed in a compression circuit 6. Audio data are processed in an audio processing circuit 1 in which the audio data are processed and rearranged by using a memory 2. The video data from the circuit 6 and the audio data from the circuit 1 are multiplexed in time base and then recorded on the tape via an error correcting circuit 8.

摘要： PURPOSE:To reduce the circuit scale and the power consumption with relatively simple control and to eliminate the jitter of an input signal by assigning an address to input picture data as the address of already outputted picture data. CONSTITUTION:With respect to picture data of the (n-1)th page recorded in a picture memory 9, data in the position indicated by the address generated by a conversion part 12 is outputted from a picture output part 10. Thereafter, picture data of the n-th page is inputted from an input part 8 to the same address, and the input/output address of the memory 9 outputted from the conversion part 12 is recorded in a memory 11. The output address of the preceding page and the input address of the current page in the memory 9 are equalized to each other, and this input/output address is delayed by one page and the input/output address of the next page is led out by the conversion part 12. Thus, the input/output page of each page is easily generated.

摘要： PURPOSE:To attain automatic retrieval of a tape count value by providing the titled device with a memory circuit for one field or one frame, a memory control circuit, a control duty discriminating circuit, a control pulse counter, and a control means for retrieving a tape. CONSTITUTION:A reproduced signal is amplified and returned to an original video signal by a reproducing circuit 5, the video signal is outputted to the memory circuit 9 and the control part 2 permits the memory control circuit 10 to store the video signal in the memory circuit 9 after the output of the video signal. Said operation is repeated several times and the contracted pictures of a large picture obtained at the time of reproducing a position recording a program searching signal are successively stored in a part of n-divided part of the memory circuit 9. In case of retrieving a tape position, a picture obtained from the memory circuit 9 and projected on a TV receiver 8, switch information of an operation part 1 and a current tape count value in the control part 2 are compared to decide whether retrieval is to be executed in the forward direction or the reverse direction and a command is outputted to a motor drive servo circuit 6.

摘要： PURPOSE:To simplify a tape editing work by recording an editing information in a magnetic tape when editing a tape, and controlling other magnetic recording and reproducing device according to the said editing information to edit one tape. CONSTITUTION:A magnetic tape to be edited is loaded on a first deck 1. When it reaches the editing position being in the reproducing state, an edit-start button is depressed, and its signal enters a control part 11. The part 11 then transmits a signal to control a second deck 2 and editing information of such as editing number to a signal processing circuit 15. The circuit 15 corrects errors of the editing information and modulates and amplifies in order to convert the information to a signal to be recorded. The converted signal is recorded in a thin layer to the control track by a recording head 16, while the editing information signal is recorded in the magnetic tape. When editing a tape, the magnetic tape is loaded on the second deck 2 and a magnetic tape to be edited is on the first deck. And when the editing button of a control section 13 is depressed, a control signal controlling the second deck 2 is outputted form the control part 11 of the first deck to that 12 of the second deck 2.

摘要： PROBLEM TO BE SOLVED: To realize continuous picture output even when a recorded program (PID) is changed at the time of specific reproduction in a device for recording/ reproducing stream data such as MPEG 2 TS in a recording medium. SOLUTION: The digital signal processor is constituted of a fixed PID generation circuit 1 for generating fixed PID, a PID rewriting circuit 3 for rewriting PID included in stream data to the fixed PID, a PAT for registering the fixed PID information, a PAT for generating a PMT packet, a PMT packet generation circuit 2, and a PAT/PMT packet insertion circuit 4 for inserting a PAT/ PMT packet into the reproduced stream data rewritten to the fixed PID. Even when the recorded program is changed at the time of specific reproduction, pictures can be continuously outputted by rewriting the PID of the reproduced stream data to always fixed PID, generating and inserting the PAT/PMT packet having the fixed PID information and allowing the PID/PAT in the stream data to coincide with the PMT packet information.

摘要： PROBLEM TO BE SOLVED: To allow a device to reproduce digital moving image data in a special reproduction mode such as a fast feeding reproduction mode that are predictively coded in compliance with the MPEG2 or the like and recorded without any further modification. SOLUTION: An in-image coded data detection circuit 1 detects in-image coded data from a received data stream and a memory 3 stores the detected data. A data amount calculation circuit 5 measures an amount of the in-image coded data. A header analysis circuit 6 analyzes header information of the received data. A data coding rate decision circuit 2 obtains a coding rate of the in-image coded data based on the information from the data amount calculation circuit 5 and the header analysis circuit 6 to decide a prescribed data coding rate. A data re-coding circuit 4 applies re-coding to the data in the memory based on the obtained coding rate. According to this re-coding, compressed data are multiplexed with the original data for special reproduction and the multiplexed data are recorded on a prescribed position of a ape.
