摘要:
Disclosed herein is a word line driving circuit in which sub-word lines are prevented from floating by using a sub-word line driver having two transistors. A plurality of sub-word line drivers is connected to one main word line. Each of the plurality of the sub-word lines includes a PMOS transistor and a NMOS transistor serially connected between a sub-word line driving voltage FX and a ground voltage. A floating prevention unit selects the main word line to a level of a threshold voltage using a driving signal having the level of the threshold voltage, thus preventing sub-word lines of a sub-word line driver, where the sub-word line driving voltage FX is off, from floating.

The present invention relates to a method or an operation for providing a personalized TV-Anytime metadata service. According to an embodiment of the present invention, there is provided a method of providing a table field element using a get_Data operation in the TV-Anytime metadata service. In the table field element provision method, a requested fields type element (RequestedFieldsType) required to designate a field of a metadata table is included in a query result value type in the SOAP query operation. A request message of the SOAP query operation is received. When the request message includes the requested fields type element for designating the query result value, a query result value corresponding to a designated table field is extracted from the requested fields type element included in the request message, and the query result value is transmitted using a response message of the SOAP operation.

Disclosed herein is a Radio Frequency (RF) modulator. The RF modulator includes a Chrominance-to-Luminance (C/L) delay compensation unit for receiving a video signal and compensating for a time delay between the chrominance and luminance signals of the video signal, and a modulation unit for receiving the video signal, which is compensated for by the C/L delay compensation unit, and an audio signal and converting the video and audio signal into a preset frequency-band RE signal. The C/L delay compensation unit and the modulation unit are packaged in a single package.

摘要:
Provided are improved methods for forming silicon films, particularly single-crystal silicon films from amorphous silicon films in which a single-crystal silicon substrate is prepared by removing any native oxide, typically using an aqueous HF solution, and placed in a reaction chamber. The substrate is then heated from about 350° C. to a first deposition temperature under a first ambient to induce single-crystal epitaxial silicon deposition primarily on exposed silicon surfaces. The substrate is then heated to a second deposition temperature under a second ambient that will maintain the single-crystal epitaxial silicon deposition on exposed single-crystal silicon while inducing amorphous epitaxial silicon deposition on insulating surfaces. The amorphous epitaxial silicon can then be converted to single-crystal silicon using a solid phase epitaxy process to form a thin, high quality silicon layer. The first and second ambients include at least one silicon source gas and may include a non-oxidizing carrier gas.

A method for successively recording data in a hybrid digital recorder. If an optical disc has no redundant area when a hybrid digital recorder in which an optical disc recorder and an HDD recorder, etc. are integrated in one body records an input data stream on the optical disc, the input data stream is temporarily stored in an HDD. If the optical disc is replaced with a new optical disc, the input data stream is temporarily stored in the HDD, and at the same time the data stream having been temporarily stored in the HDD is read and recorded on the new optical disc at a high speed. If all the data streams temporarily stored in the HDD are read and recorded on the new optical disc, the following data stream is recorded on the new optical disc. Therefore, an external input data stream such as a long-term broadcast program is distributed to a plurality of optical discs, and is stored on the optical discs without generating any lost data.
