A video processing device includes: encoder for generating a compressed video data by compressing and encoding a video data from camera unit; and system control unit for recording the compressed video data during a recording period from a recording start time to a recording end time as a video file and for recording, into recording memory, additional data as an index file that is information related to a compressed video data to be recorded in recording memory and, for reading the additional data together with the compressed video data from recording memory. System control unit records, into recording memory, the additional data recorded in the index file. The additional data is composed of additional data regarding the compressed video data recorded during the recording period and another additional data including a time code value showing a time at which a compressed video data to be recorded next is started.

To provide means for editing a content data stream quickly.A data processor according to the present invention can edit a content that has been written on a medium. The content is stored in a file as a data stream including multiple packets of the same packet size. And a file system for accessing data on a cluster size basis has been established on the medium. The data processor includes: a receiving section, which receives an instruction on a partial deletion range including the beginning of the file; and a media control section for deleting data, the size of which is an integral number of times as large as the least common multiple of the cluster size and the packet size, from the beginning of the file within the partial deletion range.

A stable crystal (Form I crystal) of (4R,5S,6S)-6-[(1R)-1-hydroxyethyl]-4-methyl-3-({4-[(5S)-5-methyl-2,5-dihydro-1H-pyrrol-3-yl]-1,3-thiazol-2-yl}thio)-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylic acid which has preferable properties and a process for preparation Form I crystal which is characterized of desolvating a solvated crystal of its compound.
摘要:
There is provided an operation mechanism for rapidly performing content list display and title menu display in a recording device itself or in other devices such as a player and a recorder while eliminating the necessity of creation or recording of the title menu data by a recording device. A data processing device includes a memory and a recording unit. The memory contains a computer-readable program which can be read out by a computer. The computer program causes the computer to search for a data stream of the content recorded in the recording medium, display the content information concerning the data stream found by the search in a menu, and execute processing enabling selection of a data stream by using the content information. The recording unit records at least one data stream in a given recording medium and records the program stored in the memory on its recording medium.
摘要:
The present invention provides a semiconductor device having a recess-structured ohmic electrode, in which the resistance is small and variation in the resistance value caused by manufacturing irregularities is small. In the semiconductor device of the present invention, a two-dimensional electron gas layer is formed on the interface between a channel-forming layer and a Schottky layer by electrons supplied from the Schottky layer. The ohmic electrode comprises a plurality of side faces in ohmic contact with the two-dimensional electron gas layer. At least a part of side faces of the ohmic electrodes are non-parallel to a channel width direction. In a preferred embodiment of the present invention, the side faces have a saw tooth form or a comb tooth form. Since the contact area between the ohmic electrode and the two-dimensional electron gas layer is increased, ohmic resistance is reduced.

In a printing system, a printing management server is provided to receive a document specific data identifying a print-out document from a mobile station and transmit the document specific data to a print server. The printing management server transmits a reservation identification data identifying a printing reservation of the print-out document to both the mobile station and a printing management terminal. The printing management terminal receives a printable data of the print-out document and causes a printer to perform printing of the print-out document when the reservation identification data is received.
摘要:
An audio/video information recording/reproducing device capable of easily implementing a post-recording function on an optical disk by using even a low-cost disk drive having a comparatively low-speed seek time. When recording a video file, it is recorded on an optical disk continuously for a duration equivalent to more than three times a seek time. When recording dubbing audio, it is recorded continuously only with constant data size at the same time with the reproducing of the recorded video file, thereby enabling concurrent real-time continuous reproducing and recording. Accordingly, concurrent reproductions of a video file and an audio file are ensured when reproducing dubbing audio.
摘要:
A data processor includes a stream assembling section which divides video and audio data into a plurality of packets, and makes a plurality of data units, in each of which a video packet representing a fraction of the video data and an audio packet representing a fraction of the audio data are multiplexed together to generate a data stream composed of a plurality of data units; and a writing section for writing the data stream on a storage medium. The stream assembling section determines what video packets and audio packets are included in each data unit, and if a portion of audio data, which is associated with the video data stored in a predetermined data unit, is missing from the predetermined data unit, then copied data, obtained by copying partial audio data including at least that missing portion of the audio data, is put into the data stream.
