摘要:
An efficient encoding/decoding apparatus of this invention comprises orthogonal transform element (10) for orthogonally transforming a digital signal obtained by allowing an analog signal to undergo analog/digital conversion, quantizer (11) for quantizing the digital signal which has undergone orthogonal transform processing, inverse quantizer (21) for inverse-quantizing a digital signal which is not yet caused to undergo inverse orthogonal transform processing, and inverse orthogonal transform element (20) for inverse-orthogonally transforming the orthogonally transformed digital signal, wherein rounding in even number direction or rounding in odd number direction is used in at least one of the orthogonal transform processing and the inverse orthogonal transform processing. Thus, accumulation of rounding errors at the time of, e.g., such a direct digital dubbing to repeatedly encode/decode digital signals such as video signals, etc. is prevented, thus making it possible to reduce picture deterioration of multi-generation characteristic.

The present invention is a video data recording apparatus, a video data recording method, a video data reproducing apparatus, a video data reproducing method, a video data recording and reproducing apparatus, and a video data recording and reproducing method that can be interfaced using an MPEG2 elementary stream and that allow an input elementary stream to be recorded to a record medium and reproduced therefrom. According to the present invention, a recording side stream converting means is disposed. The recording side stream converting means converts an input elementary stream into a device stream that is a stream suitable for a record medium. A recording means performs a recording process for the converted device stream and records the record data to the record medium. A reproducing means reproduces record data recorded on the record medium as a device stream. According to the present invention, a reproducing side stream converting means is disposed. The reproducing side stream converting means converts the restored device stream into an elementary stream.

When macro blocks each of which has a variable length are input for one picture, null syncs each of which has a unit length are generated corresponding to the format of the video data to be handled. 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.

The illuminating device includes a lens formed of a resin mold and having a portion for receiving an LED which is formed on one surface thereof, the LED received in the receiving portion, and a wiring member deposited on the receiving-portion-forming surface of the lens, and light irradiated from the LED is incident to the lens. In the method of fabricating the illuminating device, a transfer film having a conductive portion is set in a lens molding cavity and a wiring member including a conductive portion is deposited on one surface of the lens while the lens is injected and molded.
摘要:
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.
摘要:
An aqueous oxidizing acidic cleaning solution or an aqueous oxidizing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with ozone water. An aqueous reducing acidic cleaning solution or an aqueous reducing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with hydrogen water. Each of these aqueous cleaning solutions has effective cleaning power and the ORP and pH values thereof are separately controlled. Therefore, by selecting an appropriate aqueous cleaning solution according to the types of contaminants adhering to subjects during each manufacturing step, a plurality of types of contaminants can be removed by washing with one type of aqueous cleaning solution.

An information processing apparatus and method, a recording medium, and a program for removing jitter and reducing the delay of the information processing system. A substantial error is produced between accumulated value of intervals of reception time of the packets and accumulated value of time stamps of these packets. For each number of transport stream packets on which this substantial error provides one clock, a time equivalent to one clock is added to the subsequent time stamps of the transport stream packets or this time is subtracted therefrom to adjust time stamp, thereby correcting the deviation in time from reception time of the transport stream packets.

Disclosed are a statistical multiplex system, a statistical multiplex controller and a method of statistical multiplex, which can assign bit rates to program data and auxiliary data efficiently, and also improve image quality. A statistical multiplex system is provided with: a plurality of image encoders for encoding a plurality of program data; an information encoder for encoding the auxiliary data; a multiplexing apparatus for multiplexing output thereof, and a statistical multiplex controller for controlling each of the image encoders and the information encoder. The statistical multiplex controller is made to set the bit rate to be assigned to the information encoder first, and to assign the remaining bit rates to each of the image encoders.

An etchant which generates neither heat nor gas during the process, does not sublimate, is stable for a long period of time, requires no special pipings, and further requires no special treatment of waste water because of containing no organic solvents. The etchant is a solution containing hydrofluoric acid and an-oxoacid or oxoacid salt compound expressed by Mm(XOn)p (where M is hydrogen, one-to three-valence metal or NH.sub.4, m is 1 or 5, X is a halogen element, n is 3, 4 or 6, and p is 1, 2 or 3).
