摘要： When inputting moving image data into a personal computer for display or for recording on a recording medium, there often occur cases where processing cannot catch up with the input, resulting in interruption of the processing. Also, when performing conversion from an input digital signal having an arbitrary number of samples to an output digital signal having an arbitrary number of samples, prior art methods entail the possibility that the memory capacity and the amount of computation may become enormous. In view of this, according to the present invention, if the image processing cannot catch up with the input, the data is re-input for processing by utilizing information concerning the recorded position, the recorded time, or the time at which playback is to be performed; this achieves the same effect as processing continuous moving image data without interruption.

摘要： In a data transmission apparatus for transmitting digital video and audio data, a block forming circuit forms a plurality of data blocks of transmission data composed of at least one of digital video data, digital audio data, and digital auxiliary data related to the digital video data and the digital audio data. Thereafter, a grouping circuit groups a plurality of data blocks outputted from the block forming circuit so as to form transmission group data of one transmission unit block having a time length of approximately one three-hundredth second, and then transmits the transmission group data. Further, a classifying circuit preferably classifies the transmission group data into a plurality of sections, by adding section identification data to each transmission group data.

摘要： A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i.sub.1 bit/s or less are subjected to format-conversion to be recorded i.sub.1 times in the digital recording device. In the case where the data rate of the digital signals to be input is n/j bit/s, the digital signals are subjected to format-conversion so that the amount of data capable of being recorded per unit time is decreased by i/j; thus, the digital signals are recorded for a long period of time under the condition that the data recording time is prolonged j times. Furthermore, when input data to be recorded on a magnetic tape at a normal data rate by using a magnetic head mounted on a rotary cylinder is recorded, the recording device of the present invention makes it possible to select a plurality of types of track angles generated by the rotation number of the cylinder, the tape traveling speed, and the like.

摘要： A recording and reproducing apparatus is disclosed in which video signal and indexing signal are separately recorded in video signal areas and subcode areas, respectively, of diagonal tracks formed on a tape by a rotating head. The apparatus has a tape driver for driving the tape, add/erase command keys for generating add/erase command to add/erase the indexing signal, an indexing signal control for setting and resetting the indexing signal, and a recording device for recording the video signal to the video signal area and, if any, the indexing signal to the subcode area of each track. An editing control is provided for controlling the indexing signal control in response to the add/erase command such that the indexing signal is first recorded as a reset state for a first predetermined amount and then recorded as a set state.

摘要： In order to reproduce highly important information easily and at high speed, such information is composed into data of fixed length and is assigned from the beginning of a block. Without increasing the recording rate, in order to record a signal so that the highly important information may be reproduced securely, a dummy sync block is inserted immediately before a data sync block which contains the highly important information for defining or explaining the content of the signal to be recorded. To maintain the error correction capability in a normal play mode, moreover, the sync block composition which is the same as in the signal to be recorded is used for the highly important information. In particular, as for such information, by assigning the information in plural sync blocks, reproduction is securely realized also in the case of a trick play mode.

摘要： Two, HD and SD, signals are arranged so as to be identical to each other in the recorded form on a recording medium. Reciver circuits, encoder circuits, and a recording circuit for SD signals are provided. Also, a receiver circuit, an encoder circuit, and a recording circuit for HD signals are provided. In addition, a circuit is provided for identifying whether the input signal is an SD or HD signal. Accordingly, both the HD and SD signals can be recorded using one single digital VCR while no further hardware is involved. Simultaneous recording of a plurality of SD signals and high-speed dubbing of SD signals may be executed using an HD signal processing circuit.
