Image apparatus with locking operation for serial data
11146756 · 2021-10-12 · ·

An imaging apparatus allows a clock data recovery device to reestablish reception of data even when the clock data recovery device has failed to lock a phase. A reception unit includes a locking unit configured to perform a locking operation for receiving the data and a detection unit configured to detect a lock state of the locking unit. A control unit controls performing of the locking operation again by the locking unit in a case where a lock is not achieved, based on a detection result detected by the detection unit.

Selective audio visual synchronization for multiple displays
10834298 · 2020-11-10 · ·

The present disclosure generally relates to synchronization between multiple displays for audio and/or visual content. Video, movie, television, live broadcast, streaming or online content typically include visual content and corresponding audio content synchronized to the visual content, i.e., a particular audio frame is set to be play backed at the same time a particular video frame is displayed. The present disclosure provides for delaying the presentation of visual content with respect to one or more displays in order to synchronize the presentation of the visual content on the displays.

Method and system for real time synchronization of video playback with user motion

A computer-implemented method is provided for coordinating sensed poses associated with real-time movement of a first object in a live video feed, and pre-recorded poses associated with movement of a second object in a video. The computer-implemented method comprises applying a matching function to determine a match between a point of one of the sensed poses and a corresponding point of the pre-recorded poses, and based on the match, determining a playtime and outputting at least one frame of the video associated with the second object for the playtime.

Methods and systems for synchronizing data streams across multiple client devices

A server system includes one or more processors, a clock, and memory. The memory stores one or more programs configured for execution by the one or more processors. The server system receives a program manifest (e.g., a playlist) for a video from a content delivery network. The video includes a plurality of video segments. The server system parses the program manifest to identify a timeline for the video, then determines the current playback position for the video and a corresponding initial timestamp according to the clock. The server system periodically updates the current playback position for the video according to the clock and the initial timestamp. Over a span of time the server system receives requests from a plurality of client devices to view the video. For each request from a respective client device, the server system sends the current playback position to the respective client device.

Image capturing apparatus and image capturing method

In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensor 101 are recorded on a recording device 111 through a conversion processing section 201 and a recording device controlling circuit 210. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuit 203 through a pre-processing circuit 202 and an image being captured is displayed on a display section 112 with a signal for which a camera process has been performed. In a reproducing state, raw data are read from the recording device 111 at a low screen rate according to a display performance of the display section 112 and the raw data that have been read are processed are processed by the pre-processing circuit 202 and the camera signal processing circuit 203 and a reproduced image is displayed by the display section 112.

Method for synchronizing a first audio signal and a second audio signal
10687015 · 2020-06-16 · ·

A method for synchronising a first audio signal and a second audio signal coming from a same original audio signal, the method including the steps of: measuring a superimposed sound signal; performing a processing of the superimposed sound signal comprising a calculation of an intercorrelation or autocorrelation function; estimating, from a first processed signal, an absolute value of a time delay between the first audio signal and the second audio signal; modifying at least one characteristic of the first audio signal or the second audio signal; measuring again the superimposed sound signal; performing again the processing of the superimposed sound signal in order to obtain a second processed signal; estimating the sign of the time delay based on the second processed signal; synchronising the first audio signal and the second audio signal.

If another communication apparatus is reproducing a content stored in an external apparatus, a reproduction instruction for causing a communication apparatus to reproduce a content stored in the external apparatus is transmitted from the another communication apparatus to the communication apparatus. The communication apparatus performs reproduction preparation for the content based on the reproduction instruction, and then transmits a wireless signal to the another communication apparatus. The another communication apparatus obtains a reproduction start position of the content, based on reception of the wireless signal, and transmits the obtained reproduction start position to the communication apparatus.
