Abstract: A waiting time until editing starts is shortened. Metadata that are a part of metadata are transferred from an optical disc set in a disc unit to an HDD in an editing device. The metadata are text data including a clip ID and continuing time information of material data, and they are small in information quantity. Thus, a waiting time for waiting for the completion of metadata transfer does not take place, and immediately after the optical disc is set editing processing can start. An editor selects a clip in accordance with a clip ID included in the metadata. Further, the editor selects a used portion of the clip in accordance with the continuing time information included in the metadata. Editing data are generated on the basis of these selected results.

Abstract: A method for controlling a scanning apparatus for scanning a continuously moved object includes seizing the actual momentary position of the moving object, and controlling the time instant or period in which image information is captured by the scanning devices in dependence of the actual momentary position of the object. The scanning apparatus in which the method is used includes a multiplicity of line scanning devices arranged adjacent to each other in the direction of the movement of the moved object. Each of the line scanning devices has a multiplicity of pixels that are arranged adjacent to each other in a direction across a path along which the object is moved. The pixels of the line scanning devices accumulate charges according to the amount of incident light. A controlling means is provided for transferring the charges accumulated in individual pixels to pixels in the adjacent line scanning device in synchronism with direction of the movement and the speed of the moving object.

Abstract: A moving image editing method uses a recorder apparatus and an editor apparatus. The recorder apparatus records into a recording unit by use of a file format in which index data, which includes the reproduction information of the data of the frames of moving image data, is written after that data of the frames of the moving image data. According to the moving image editing method, while the data of the frames of the moving image data being recorded into the recording unit, the index data related to the data of frames already written in the editor apparatus is transferred from the recorder apparatus to the editor apparatus. The editor apparatus reads, based on the index data, the data of the frames of the writing file so as to perform a real time edition of the moving image data.

Abstract: An Linear Time Code (LTC) receiver for receiving and decoding a LTC frame of the type used in connection with film and television and accompanying audio includes a first counter that measures the number of reference clock periods within the duration of a bi-phase mark signal interval to yield a timing reference for extracting the payload from the LTC frame. A second counter detects a sync field within the LTC frame to establish the LTC frame direction. A third counter serves to count the number of symbols in the LTC frame. A state machine responsive to the counts of the first, second and third counters, serves to (a) detect a valid synchronization sequence within an incoming LTC frame; (b) determine the LTC frame direction, (c) decode (extract) payload information from the LTC frame; and (d) transfer the payload information in an order determined by the LTC frame direction.

Abstract: A main processor manages serial communication with one or more external devices by establishing the requisite tasks needed for serial communications. For example, these tasks can include (1) serial device handling, (2) protocol encapsulation, and (3) low-level communication with external devices. A priority is assigned to each of the tasks so that timing requirements are met, while maximizing processor efficiency of the main processor. Upon its completion, each lower priority task initiates execution of a next higher priority task to synchronize data processing with data communication.

The encoding method includes: a frequency conversion step (s101) of converting the interlaced image to coefficients of frequency domain having predetermined frequency ranges in a vertical direction and a horizontal direction, respectively; and a weighting step (s102) of weighting the coefficients of frequency domain for each frequency band. In the weighting step, a weighting factor used for weighting a coefficient of a frequency band exceeding a predetermined frequency in the vertical direction is substantially equal to or larger than a weighting factor used for weighting a coefficient in a frequency band exceeding the predetermined frequency in the horizontal direction.
