Abstract: An edit-to-it function of an editing system allows an editor to combine linear editing with non-linear editing. A linear source, such as a magnetic tape, may be identified as an edit source, as well as already predigitized material. When the linear source is selected as an edit source, an edit-to-it file is created that indicates the status of the source--which portions are already digitized and which are not. The editor identifies an in-point on the edit and an in-point on the source. The source prerolls, as applicable, to the in-point and lays the shot into the edit while simultaneously recording the shot including a handle prior to the in-point into a digital storage device. When the editor identifies the end of the shot, either by a predetermined out-point or on-the-fly, the source stops and the recording terminates.

Abstract: According to a first aspect of the invention, digital image data are recorded in the form of compressed codewords with check information and flags. The flags indicate codewords containing uncorrected errors. Each time the data are copied, error detection and correction are performed and the flags are updated to indicate any new uncorrectable errors that are detected. The flags can be used for error concealment, to avoid error miscorrection, and to permit the check information to be regenerated each time the data are copied. According to a second aspect of the invention, when image data are copied, the same check information is used to perform error detection and correction twice. Flags identifying uncorrected errors can be transferred from the first error-detecting-and-correcting process to the second.

Abstract: A method and system produces a digital video with comments.

In response to reviewer request to continue play of the video after the pause, the system continues play of the video without the comments. The system also pauses the video when the comments are displayed during the subsequent play of the digital video.

Abstract: A magnetic recording and reproducing apparatus capable of recording video, audio and other information on a magnetic tape by, for example, the helical scanning method. A rotary head is rotated at an m-fold speed to record intermittent tracks on the magnetic tape so that real-time simultaneous monitoring is performed.

Abstract: A data recording method by which data of a compact disk can be recorded well onto a magneto-optic disk of the ISO format. Data of a compact disk are recorded onto a 5-inch magneto-optic disk (ISO format) of the 512 bytes/sector type of the CS system. The sector size of the magneto-optic disk is 610 bytes. Data included in one sector (98 frames) of the compact disk are 2,352 bytes and subcodings of P to W are 96 bytes. Data for one sector are divided into data groups A to H to construct a data format. A CRC is added to each data group. Further, a parity 2 (Reed-Solomon code) is added. Data (3,050 bytes) for one sector of the compact disk to which the CRCs, parities and so forth are added are recorded across 5 sectors of the magneto-optic disk. Data of a compact disk can be recorded onto a magneto-optic disk having a different sector size, and since error correction codes or error detection codes are added using the remaining area, the data can be recorded with a high degree of accuracy.
