A video recording apparatus with a pre-event circulation recording function is provided. A limitation on memory capacity may be removed by recording a pre-event video directly on a nonvolatile storage medium, such as a hard disk drive (HDD), without using a buffer according to a circulation recording method during pre-event recording performed to record videos before and after an event occurs.

A device and method allows a user to create a mark corresponding to a moment in time of a captured recording to provide later viewing of a portion of the recording corresponding to the moments in time.

The recording and playback device includes a recording unit configured to record AV data on a recording medium as an AV data file, a file management unit configured to provide an access system depending on a use to the AV data file, an updating unit configured to update file information about access restrictions on the AV data file depending on the access system being provided depending on a use, based on a rule associated with the access system, and a communication unit configured to open the AV data relating to the updated file information to the outside.

A recording apparatus including: a recording unit configured to record on a recording medium a file that includes sequentially obtained data; a repair unit configured to repair a predetermined file that needs to be repaired out of files recorded on the recording medium; and a control unit configured to control the recording unit so that recording of data is stopped in response to a drop of a free capacity of the recording medium to a predetermined capacity during recording of the data, the control unit being configured to determine the predetermined capacity based on a data amount necessary to repair the predetermined file that is recorded on the recording medium, to thereby control the recording unit so that the recording of the data is stopped in response to a drop of the free capacity of the recording medium to the predetermined capacity during the recording of the data.

The present invention relating to an information processing device, information processing method, playing device, playing method, and program that enables playing of stereo image (3D image) contents appropriately. In the case that 3D playing using Base view video and D1 view video is instructed, “10000.ilvt (ref_to_D1-B_interleaved_file_name) described in interleaved_file_info ( ) of the PlayList file is specified, and Base view video chunks and D1 view video chunks are read out from an optical disc through a UDF file system. The Base view video chunks and D1 view video chunks that are read out are supplied to a decoder unit and played. The present invention is applicable to a playing device compatible with the BD-ROM standard.

Aspects of the disclosure relate to systems and methods of recording video frames from a computing device by a management device. The management device may receive video frames from the computing device. In response to receiving the video frames, the management device may process the video frames in a first-in-first out (FIFO) order to generate processed video frames according to a recording method, store the processed video frames in the FIFO order in the memory of the management device, and then release the memory occupied by some of the processed video frames in the FIFO order based on a memory releasing condition defined by the recording method to store the processed video frame. The memory releasing condition is determined by multiple optimized parameters of the recording method. The recording method may be a sliding window recording method, a multiple-window fixed size recording method, or a multiple-window dynamic size recording method.

A method of placing an ad in a video in an original format may include producing a transcoded video in a proxy format which is a representation of frames of the video in the original format. The transcoded video in the proxy format is convertible to other formats for output. The method may include selecting the ad from a set of ads, selecting a location within a frame of the transcoded video where the ad is to be placed, selecting frames of the transcoded video where the ad is to be placed, placing a placeholder in the transcoded video in the selected frames at the selected location, and storing the transcoded video in the proxy format. When the transcoded video is presented to a user on a display device, the selected ad is inserted in place of the placeholder.

The present technology relates to a reproducing apparatus for enabling an appropriate video depending on a viewing environment to be reproduced, a reproducing method, an information processing apparatus, an information processing method, a program, and a recording medium. The reproducing apparatus according to the present technology analyzes reproduction management information describing therein type information on a form of providing a HDR video which is compatible with a SDR video with a standard luminance range and whose luminance range is wider than the standard luminance range or a form of providing the SDR video compatible with the HDR video. Further, the reproducing apparatus acquires and reproduces encoding data of the HDR video or encoding data of the SDR video provided in a form indicated by the type information. The present technology is applicable to Blu-ray Disc players.

The present invention relates to implementing recoil activated video recording through a digital imaging system, wherein the video recording is initiated as the digital imaging system detects a firing event from a smart weapon scope device. The digital imaging system captures the video recording sequence, wherein the sequence captures the video at the specific instance when the firing event is detected, for a specific period of time before the firing event is detected, and for a specific period of time after the firing event is detected.

A digital information recording apparatus includes a recording circuit for recording information of a retention period included in the digital information and indicating a period for permitting the digital information to be held in the recording medium, starting with a time at which the digital information is recorded on the recording medium; and information of a playback permission period included in the digital information and indicating a period for permitting the digital information to be played back starting with a time at which the information is reproduced initially following recording of the digital information on the recording medium, permitting temporary recording or copying for the information permitted for “copy never” or “copy one generation.”
