130 results about "Hard disk recorder" patented technology

A hard disk recorder (HDR) is a system that uses a high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to reel-to-reel audio tape recording and video tape recorders, and provide editing capabilities unavailable to tape recorders. Audio HDR systems, which can be standalone or computer-based, typically include provisions for digital mixing and processing of the audio signal.

Video recording file management method and device for easily preventing disk fragments from being generated

The invention discloses a video recording file management method and device for easily preventing disk fragments from being generated. The method comprises the following steps that firstly, disk formatting is conducted on a video recorder, a disk is fixedly set to one subarea or multiple subareas, and different formatting methods provided by an operating system are applied to different file systems; secondly, a video recording file index database is established, and the video recording file retrieval service is provided; thirdly, the size of each video recording file is fixed and marked as A (Byte); fourthly, when the disk is not fully occupied, a general file establishment and write-in method is applied; fifthly, when the disk is fully occupied, the file which is established earliest on the disk is found out and used as a new video recording file, write-in is conducted from the start position of the file in a covering mode, and the step is repeated. The video recording file management method and device for easily preventing disk fragments from being generated have the advantages of being simple, easy to achieve and compatible with different file systems due to the fact that the management method and device capable of easily preventing the disk fragments from generating the video recording file are established on a general file system; the problems that after audio and video data are written in a hard disk recorder in a circulating mode for a long time, a great number of disk fragments are generated and the system operating efficiency is influenced are solved.

Receivers for television signals

A Hard Disk Recorder (HDR) (3) is arranged to receive signals signals defining television programmes and television programme schedule data. The HDR receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel. The HDR is arranged to output the programme schedule data for display on a television screen (2). The HDR comprises a hard disk (16) for recording received television programmes. A remote control (28) is provided to select television programmes to be recorded from the displayed programme schedule. Furthermore, the HDR is arranged to receive additional programme schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed television programmes according to schedule. The hard disk is operable to record simultaneously two different television programmes received in different channels. Also, the HDR is operable to replay a currently broadcast programme offset in time. The time offset can be overcome by playing back the part of the programme inside the time offset at an increased frame rate. Furthermore, the HDR is arranged to receive transition signals indicating transitions between parts of programmes, such as transitions between advertisements and the “actual” programmes. The HDR is operable to use these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.

InactiveCN108688507APrevent parkingTiming switchCharging stationsArticle advertisingNew energyParking space
The invention relates to the field of electrical equipment, in particular to a new energy car charging pile. The new energy car charging pile comprises an advertising box and a charging pile body arranged inside the advertising box. The charging pile body comprises a charging module and charging guns mounted on the two sides of the charging module. The charging guns penetrate through the two sidesof a box body correspondingly and are arranged on the outer side of the box body. Automatic telescopic winding boxes are mounted on the two sides of the advertising box. Charging cables are wound inside the automatic telescopic winding boxes. Intelligent parking locks arranged on two parking spots are mounted on the two sides of the front portion of the advertising box correspondingly. Intelligent cameras are mounted on the two sides of the advertising box to be electrically connected with a hard disk recorder mounted in the advertising box. The advertising box can deliver visual advertisingto a parking user. The Intelligent locks are mounted on the parking spots, thus the situation that social vehicles are parked on the parking spots special for new energy cars at will is avoided; the user can be prevented from forgetting to pull the charging guns out through the automatic telescopic winding boxes, the possibility that the charging cables are rolled by wheels is also avoided, and ifthe advertising box or the charging pile body is damaged, a responsible person can be looked for by viewing videos.
