摘要:
In recording information, meta data defined in SMPTE 298M and 335M, buried in video and audio material signals to be recorded to a magnetic tape (30) are extracted, the thus extracted meta data or meta data generated from information other than the material signals, are written to a contactless memory tag (37), whereby it is made possible to acquire meta data about material signals recorded in a recording medium without actual reading of the material signals in the recording medium and use the meta data for search, validation, etc.
摘要:
A method for producing a GaN crystal capable of achieving at least one of the prevention of nucleation and the growth of a high-quality non-polar surface is provided. The production method of the present invention is a method for producing a GaN crystal in a melt containing at least an alkali metal and gallium, including an adjustment step of adjusting the carbon content of the melt, and a reaction step of causing the gallium and nitrogen to react with each other. According to the production method of the present invention, nucleation can be prevented, and as shown in FIG. 4, a non-polar surface can be grown.

A production method is provided that enables to produce a large-sized bulk silicon carbide (SiC) crystal of high quality at low cost. A large-sized bulk silicon carbide (SiC) crystal of high quality can be obtained at a lower temperature by reacting silicon (Si) and carbon (C) produced from a lithium carbide such as dilithium acetylide (Li2C2) with each other in an alkali metal melt and thereby producing or growing a silicon carbide (SiC) crystal. FIG. 17 shows a high-resolution TEM (HR-TEM) image of the resultant 2H—SiC crystal. A preferable lithium carbide is dilithium acetylide (Li2C2). A preferable alkali metal melt is a melt of lithium alone.

摘要:
The present invention provides a producing method with which large silicon carbide (SiC) single crystal can be produced at low cost. Silicon carbide single crystal is produced or grown by dissolving and reacting silicon (Si) and carbon (C) in an alkali metal flux. The alkali metal preferably is lithium (Li). With this method, silicon carbide single crystal can be produced even under low-temperature conditions of 1500° C. or lower, for example. The photograph of FIG. 3B is an example of a silicon carbide single crystal obtained by the method of the present invention.

摘要:
A shortest cut duration is a minimum required period between an edit point set on a stream of pictures such as an MPEG stream and the next edit point set on the stream. Restrictions are made on the shortest cut duration lenient in a process to seamlessly reproduce a result of editing the stream in order to enhance the freedom of editing in carrying out a process of editing the stream. A controller detects each edit point set on the stream and, for the edit point, the controller identifies fewest possible pictures, which are not to be displayed but must be decoded first before decoding a picture to be displayed after the edit point. Then, the controller finds a start point representing a timing to start a process of decoding the one or fewest possible pictures. Subsequently, the controller controls processes carried out by decoders to decode the stream in picture units on the basis of the start point, and controls a switcher to select one of outputs of the decoders on the basis of the edit point.
摘要:
In a packing unit (PU) composed of five sync blocks, Discrete Cosign Transform (DCT) blocks of compressed and encoded data are packed to a sync block. When same DCT blocks are not placed in a sync block, the remaining DCT blocks are temporarily placed in another sync block. In a high speed reproducing mode, a detecting portion detects whether or not the current PU mixes with data of another PU. The detected result is supplied as a flag to an unpacking portion along with a sync block. The unpacking portion removes a sync block that mixes with data of another PU. The unpacked data is supplied to a Bit Rate Reduction (BRR) decoder. The BRR decoder performs a decompressing process.

A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN0 and LN1 to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch0 and Ch1 with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN0 and LN1 at the beginning of one horizontal interval.
