Some embodiments of an image capturing apparatus include a first display unit capable of displaying a captured image and a second display unit configured to display information related to image capturing, where the apparatus comprises a generating unit configured to generate a timecode corresponding to a frame rate at which an image capturing unit performs image capturing; a first display control unit configured to control so as to display the timecode generated in the generating unit on the first display unit at first intervals; and a second display control unit configured to control so as to display the timecode generated in the generating unit on the second display unit at second intervals that are longer than the first intervals.

This invention provides an electronic apparatus which comprises a TIME-CODE terminal configured to output a time code signal which an external apparatus utilizes to perform synchronization related to a video, and a control unit configured to output a time code signal in which a bit in a predetermined field in the time code signal is set to a predetermined value, from the TIME-CODE terminal.

This disclosure provides techniques of synchronizing the playback of two recorded videos of the same surgical procedure. In one aspect, a process for generating a composite video from two recorded videos of a surgical procedure is disclosed. This process begins by receiving a first and second surgical videos of the same surgical procedure. The process then performs phase segmentation on each of the first and second surgical videos to segment the first and second surgical videos into a first set of video segments and a second set of video segments, respectively, corresponding to a sequence of predefined phases. Next, the process time-aligns each video segment of a given predefined phase in the first video with a corresponding video segment of the given predefined phase in the second video. The process next displays the time-aligned first and second surgical videos for comparative viewing.

A signal processing device is disclosed, which includes a plurality of channel receivers, a plurality of time code processors in one-to-one correspondence with the channel receivers, a timing generator, a signal processor and a transmitter, wherein each channel receiver is configured to parse an audio-video signal which has a data format defined by the SDI protocol and including a time code that characterizes time information. Each time code processor is configured to extract the time code from a parsed audio-video signal obtained by a corresponding channel receiver, and form first frame image data including a frame time code. The signal processor is configured to form an absolute frame output image based on multiple channels of the first frame of image data, frame time codes therein, and an internal clock signal generated by the timing generator. The transmitter is configured to transmit the absolute frame output image for display.

An information processing apparatus is provided, in which content and position information generated independently of each other are recorded in a recording medium. The apparatus includes a recording medium in which the content and the position information are recorded and a deletion unit deleting position information temporally associated with a piece of the content from the recording medium when the piece of content is deleted from the recording medium.

Techniques are provided for associating comments with certain positions within a video (or audio) timeline. Multiple users compose comments, such as questions, and cause those comments to be stored in association with the video. Each comment is stored in association with a specific point or section in the video timeline. Later, another user can view the comments and select a particular comment, which causes the video to be played at the position in the timeline associated with the particular comment. Additionally or alternatively, playing a particular portion of a video may cause one or more comments that are associated with the particular portion to be displayed.

The present invention discloses a synchronized audio playing method, apparatus, and system for playing audio synchronously. By outputting designated data using a designated data buffer area before arrival of the starting time point of synchronous playing so as to make an audio link in a stable state, the method shuns from the impact of factors like system process scheduling interruption and system hardware on synchronous playing, thereby enhancing the precision of synchronous playing; moreover, upon arrival of the starting time point of synchronous playing, by computing a tuning amount of the audio data in the local synchronization buffer area, adjusting the audio data in the local synchronization buffer area according to the tuning amount, and meanwhile performing output playing on the tuned audio data, the method achieves audio synchronization play. Compared with the prior art, the present invention needn't add playing timestamp information to an audio data stream, and the playing terminal needn't process timestamp information during the entire playing procedure, thereby effectively increasing the flexibility of synchronous playing.

An apparatus is disclosed for recording data to produce a localized panoramic image of a street. The apparatus uses a camera and a device for satellite-based position and time determination, as well as a storage unit. A preparation device is provided which encodes time data of the device for satellite-based position and time determination into a format recordable for the camera and forwards this to the camera. The camera is designed to simultaneously record these data and record a continuous film. The storage unit stores the film with the time data as well as position and time data obtained from the device for satellite-based position and time determination. Furthermore, the apparatus operates in accordance with a method for producing a localized panoramic image.

In an embodiment a method includes receiving, by an electronic device, an annotation request, wherein the annotation request is used to request to annotate a playing start-end time period of each text unit in a text corresponding to a target audio, and wherein a text unit is at least a character, a word, or an expression, obtaining, by the electronic device, the playing start-end time period of each text unit in the target audio based on a fundamental frequency of the target audio, obtaining, by the electronic device, an annotation file based on annotating the playing start-end time period of each text unit in the text based on the playing start-end time period of each text unit in the target audio and outputting, by the electronic device, the annotation file.
