Title: Search information generation method for recorded digital data stream and search method and device using the generation method
Inventor: JE YON YOO
IPC: H04N5/76
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To accurately search a received data stream and the data recorded on a recording medium such as a video disk without using extra information. SOLUTION: A data stream is partitioned by a recording unit body and also recorded, and the time information to be searched is also recorded. A desired recording position is searched by means of the time information. The time information on the data stream is recorded in the same format as a time format of the management information and defined as the arrival lower rank time of the data stream in a search operation mode. The time information is also compensated and accurately calculated against a start position of the recording unit body set by the insufficient resolution of the search information that is displayed as an increment of the fixed unit time.  Thus, a user can quickly and accurately search his/her desired reproducing position without using the different additional information showing the difference between the start position of the recording unit body and the position that is designated by the arrival time increment information that accesses the recording unit body.

Title: Light-receiving circuit
Inventor: CHIKUMA NAOYUKI
IPC: H04B10/40
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To solve the problem that it is difficult to use a light-receiving circuit in a high-frequency region, due to the increase of an input capacitance at integration of an input protecting circuit, and that it is impossible to sufficiently realize the cost reduction and miniaturization of the light-receiving circuit, using two EA elements as a level attenuating element and a light-receiving element. SOLUTION: A PIN photodiode 13 is used as a light-receiving element, and when it is detected that the opto-electric conversion output signal is beyond a certain fixed level by a detecting circuit 14, the permeability of an EA element 11 is reduced via an EA control circuit 12, and the signal is inputted through the EA element 11 to a PIN photodiode 13. Thus, the level of an optical signal to be made incident to the PIN photodiode 13 can be always kept at a certain fixed level or lower, without having to integrate input protecting circuit or without having to use two EA element.
