The present invention provides an image data processing method of recording image data coded with the MPEG (Moving Picture Experts Group) technique to a recording medium. For transition of the bit occupancy in a VBV buffer to a target value, the initial value of a bit occupancy in a VBV buffer is calculated on the basis of auxiliary data read from a recording medium, a comparison is made between the target and initial values of the bit occupancy, and the number of bits for assignment to each GOP of to-be-coded image data correspondingly to the result of comparison.

Image data processing device and method

Recording data having a data format corresponding to a predetermined digital recording method is generated and the recording data of two tracks in the digital recording method is continuously recorded in one track on magnetic tape. In addition, in this case, control data indicating the arrangement of the frequencies of pilot signals in each track on the magnetic tape is inverted at an interval of two frames in the NTSC system and of one frame in the PAL system and placed in the recording data.

Magnetic recording apparatus and method therefor, and magnetic recording and reproduction apparatus and method therefor

A connector device for connecting information-handling apparatus has a common jack connected to a first information-handling apparatus, a plurality of plugs connected respectively to a plurality of second information-handling apparatus having respective different impedances, the plugs being selectively connectable to the jack, and a determining circuit for, when one of the plugs is connected to the common jack, applying a predetermined voltage to a contact of the connected plug through an impedance element, detecting a voltage between the contact of the connected plug and a ground contact thereof, detecting an impedance between the contact of the connected plug and the ground contact thereof depending on the detected voltage, and determining the type of the plug or the type of the second information-handling apparatus connected to the plug depending on the detected impedance.
