摘要： An external color frame is synchronized with a local color frame without producing a pixel position error. A frame synchronizer synchronizes a frame from an external television signal with that of a local television signal. A wide screen oriented high definition television signal is used as the external television signal, the image quality of which is improved by adding a support signal to the main screen signal. A memory is provided to receive and store the external television signal and the external signal is read from the memory after a predetermined time passes when the frame difference between the external and local television signals is at least one frame. In this instance, only the support signal in the readout of the external television signal is corrected by a low pass filter in order to match the pixel position of the support signal to that of the main screen signal.

摘要： A magnetic recorder/reproducer converts two-channel analog signals into digital signals by a sample-and-hold/A-D converter circuit (3) and controls addresses in a memory circuit (4) by a memory address control circuit (5), to distribute the digital signals into odd sample groups and even sample groups per each channel for arraying the odd sample groups and the even sample groups of the same channel in alternate scanning intervals, thereby to write the same in the memory circuit so that the odd samples and the even samples of the same channel are arrayed in positions separated from each other along the direction of scanning by rotary heads (10, 11). The digital signals thus permutated are modulated by a modulation circuit (7), to be recorded in a magnetic tape by the rotary heads. The digital signals reproduced by the rotary heads are demodulated by a demodulation circuit (14), to be stored in a memory circuit (15). A memory address control circuit (16) controls addresses so as to permutate samples of the reproduced digital signals stored in the memory circuit to be in the original array thereof. The reproduced digital signals read from the memory circuit are converted into analog signals by a D-A converter (18), to be outputted through a low-pass filter (19).

摘要： A magnetic recording and reproducing apparatus records audio signals digitized by rotary heads (9, 10) on a magnetic tape (12), and reproduces the recorded audio signals. Clock signals and time code data are extracted from externally inputted time code signals by means of a demodulating circuit (72), and phase difference between the frame clock signals and the reference signal is detected by a phase difference detecting circuit (74). A microcomputer (23) assigns the phase difference information and the time code data to sub code packs and stores the same in the memory circuit (40). The stored phase difference information and the time code data are recorded on the magnetic tape. In reproduction, the microcomputer outputs and original time code signals responsive to the reproduced phase difference information and the time code data.

摘要： An error correcting and controlling system forms syndromes S.sub.1 and S.sub.2 for each of a set of reproduced, sampled signal words and error correcting words P or Q and also forms a syndrome S.sub.i =S.sub.1 .sym.T.sup.i-7 S.sub.2 by using the result of a CRC check of the set of sampled signal words. An error position i is determined by three zero counters which respectively indicate S.sub.1 .noteq.0, S.sub.2 .noteq.0 and S.sub.i .noteq.0. Alternatively, the system may further include three counters for respectively counting errors developed in the set of sampled signal words, and the error correcting words P and Q, the errors being detected by a CRC check circuit. When any one of the counters counts an error and the remaining counters count no error with S.sub.1 .noteq.0, S.sub.2 .noteq.0 and S.sub.i .noteq.0, a control signal is generated to perform a concealing operation, such as a means value interpolation, etc.

摘要： An address designating method of a memory is performed by dividing the addresses of the memory to row addresses and column addresses. The writing of data in the memory is performed by the following steps. Namely, while the row addressing is maintained in a predetermined value (for example, 7d+1), the column addressing is incremented one by one. When the column addressing reaches 3, the row addressing is decremented by 4d+1. Each time the row addressing is decremented by d, the column addressing is decremented one by one in accord therewith. The reading of the data from the memory is performed by the following steps. Namely, each time the row addressing is incremented by d, the column addressing is also incremented one by one in accord therewith. When the column addressing reaches 3, the row addressing is decremented by 3d+1. With the row addressing kept in 0, the column addressing is decremented one by one.
