Patent number: 7190882Abstract: An in-car video system with inputs for one or more analog or digital video cameras, one or more of which may be wireless, and having inputs for one or more microphones, one or more of which may be wireless. The system includes circuitry to digitize the input signals, if necessary, merge the data with system status data and compress the resulting data with any algorithm, preferably MPEG 4. A digital data cassette recorder records the compressed data, and a decompression circuit and active matrix display and audio channel provide monitoring capability of live video and audio. In some embodiments, a hard disk continuously records all data and archives previously recorded data to tape when so ordered to provide after-the-fact recording capability. In some embodiments, anti-tampering circuitry renders the recorded data tamper-proof, and a local playback circuit allows local playback of either live or previously recorded video.Type: GrantFiled: March 19, 2001Date of Patent: March 13, 2007Assignee: Applied Concepts, Inc.Inventor: Robert S.

Patent number: 7184652Abstract: There is provided a digital video recording/reproduction apparatus which can precisely perform a reproduction process while preventing noise generation even when a program has been recorded in overwriting fashion, such being realized by detecting a discontinuous portion in the stream at the time of reproduction. A PMT_PID or an ES_PID contained in each packet of a partial TS is recorded on a recording medium so as to take a different value each time there is a discontinuity in a stream. As a result, in a reproduction process of a recording medium which has been recorded in this manner, especially when data which has been overwritten on an already-recorded medium is to be reproduced, the discontinuous portion in the stream (i.e., the recorded portion immediately following the overwritten portion) can be easily determined. Thus, a precise reproduction process can be performed while preventing noise from being generated.Type: GrantFiled: July 22, 2002Date of Patent: February 27, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Keishi Sugimoto, Naoe Kato

Patent number: 7167632Abstract: A broadcast network sends audiovisual transmissions to a plurality of receivers. The transmissions contain also short audiovisual transmissions, typically advertising spots and information for triggering the displaying of an advertisement page. The receivers are furnished with a large recording capacity that allows the recording of several short audiovisual transmissions. At a time defined by the information transmitted in the audiovisual transmissions, the short audiovisual transmissions are, upon reception in the receiver, automatically replaced by transmissions of the same type previously recorded in the receiver. The receiver resumes normal displaying of the transmissions at the end of the broadcasting of the audiovisual transmissions of a certain type. According to an improvement, the recording of the transmissions can be performed according to the preferences of the user. The preferences of the user are defined during a configuration phase.Type: GrantFiled: March 14, 2001Date of Patent: January 23, 2007Assignee: Thomson LicensingInventors: Michel Cosmao, Louis Chevallier, Pierre Houeix

Patent number: 7133599Abstract: A realtime data recording method allows recovery of recorded file data upon occurrence of a fault for use as a readable file. Prior to recording, initial management data are generated such that the entire area on a recording medium 1 is reflected as a recording range. After the initial management data has been recorded, data recording is started. During the recording, a writing status of the recording medium (or apparatus) is set as in-writing status, and realtime sector information generated in parallel to data recording is recorded in a non-volatile memory for management of a recording status. Upon restarting after a recording fault, the in-writing status of recording medium 1 is read to see if the medium has been set open, and inconsistency between the recording information of the sector information and the in-writing status recording information is detected. Correct management data is recorded and re-recorded onto the recording medium.Type: GrantFiled: August 20, 2003Date of Patent: November 7, 2006Assignee: Hitachi, Ltd.Inventors: Tsukasa Hasegawa, Masahiro Kageyama, Tamotsu Ito

Patent number: 7113691Abstract: A method of and an apparatus for writing data on and reading data from a recording medium such as an optical disc, a magnetic disc and, particularly, a tape are described. When a block of the medium is defective, the data to be written in said block is stored in an auxiliary memory. Subsequently, all the data from the auxiliary memory is copied to a predetermined spare area of the medium. Conversely, when the medium is read, data is first copied from the spare area of the medium to the auxiliary memory. If a block then appears to be defective, the correct information is read from the auxiliary memory. Thus, it is possible to write and read a real-time audio and/or video signal in a reliable manner without the possible presence of any defective blocks affecting the data transfer rate.Type: GrantFiled: October 23, 2000Date of Patent: September 26, 2006Assignee: Koninklijke Philips Electronics N.V.Inventor: Ewout Brandsma

Patent number: 7113692Abstract: A recording/reproducing device has an NTSC decoder which receives a video signal and outputs a video signal, an MPEG audio encoder which receives an audio signal and outputs an audio signal, and a synchronous control circuit which detects a synchronizing signal from the video signal input to the NTSC decoder and uses that signal to generate an output synchronizing signal that is different from the input synchronizing signal. The output synchronizing signal is used to output the video signal from the NTSC decoder. In the recording/reproducing device, the NTSC decoder and the MPEG audio encoder provide a delay to the input video signal and audio signal, respectively, and output the video signal and audio signal in accordance with the output synchronizing signal generated by the synchronous control circuit.Type: GrantFiled: March 16, 2001Date of Patent: September 26, 2006Assignee: Sony CorporationInventors: Hajime Nitta, Toshimichi Hamada, Masashi Ohta, Kiyoshi Ota
