The invention is related to a device and method for cordless recording, telecommunication transmission, and processing of three special ECG leads by the means of the mobile device (1) and diagnostic-calibration center (2) where the reconstruction of standard ECG leads is performed. Reconstruction parameters are determined previously by calibration for each patient. In urgent situation, a patient (3) performs recording of three special ECG leads with the mobile device (1), and sends the memorized data to the diagnostic-calibration device (2) via a cellular telephone (4). The patient can trace the process of recording and sending the data with the help of sound and light indicators. Diagnostic-calibration center (2) is equipped with a PC computer (6) connected to a receiving cellular telephone (7) and calibration ECG device (8) with 14 electrodes. Ten electrodes are grouped into a standard 12-channel ECG cable, while the remaining four are used for recording of three special ECG leads and are grouped into a separate box (9) with integrated electrodes arranged identically as the integrated electrodes on the mobile device (1).

A TSP signal that is a measurement signal is generated N times by a signal generating portion. The generated TSP signals are supplied to a steel-echo apparatus. Reverberation generated by the steel-plate echo apparatus corresponding to the TSP signals is arranged N times corresponding to the start points of the TSP signals and synchronously added by a synchronously adding portion. Generating impluse signal is convoluted by an inverse function to TSP signal. The added result of the synchronously adding portion is supplied to an impulse response converting portion. By dividing the added result by the inverse characteristics of the TSP signals, the added reverberation is converted into an impulse response. The impulse response data obtained by the converting portion is recorded to for example a CD-ROM and supplied to a reverberator. The reverberator reproduces an impulse response recorded on the CD-ROM and performs a convolution calculation process for the input signal. Thus, reverberation of the steel-plate echo apparatus can be reproduced.

When macro blocks (MB0 to MB9) each of which has a variable length are input for one picture, null syncs (NULL1 to NULL5) each of which has a unit length are generated corresponding to the format of video data to be handled. Each null sync contains length information and a data portion. The length information represents 0. The data portion is filled with data [00]s. Corresponding to the length information, an overflow portion of a macro block is detected. The overflow portion is successively packed to macro blocks each of which is smaller than the unit length. Thus, each macro block is packed in the unit length. Since the length information of each null sync represents 0, the overflow portions are packed after the length information of each null sync. With null syncs, one format of video data can be matched with another format. In addition, with null syncs, overflow portions are packed. Thus, the record medium can be effectively used.

Replacement of a recording head on a recording apparatus is detected on the basis of a serial number allocated to each recording head. The recording head also carries head characteristic information such as color information, shading information and so forth. When the recording head is replaced with a new one, the head characteristic information of the newly mounted recording head is automatically stored, so that head driving conditions are automatically determined to optimize the recording conditions without requiring any manual adjustment. Recovery operation is automatically executed when replacement of the recording head is detected, so that required recording conditions are recovered without manual instructions.
