After a command to stop recording a video is received, an image capture device may buffer footage in a buffer memory. The buffer memory may be used as a post-capture cache. The footage buffered in the buffer memory may be appended to the end of previously captured footage, appended to the beginning of subsequently captured footage, and/or used to bridge two separately captured footage.

A video output apparatus that outputs video data in a first format to a conversion apparatus that converts and outputs the received data in the first format into data in a second format. The conversion apparatus sequentially outputs a blank signal, a vertical synchronization signal, and a blank signal. The video output apparatus includes a frame image data output unit that outputs the first frame image data to the conversion apparatus, a blank signal output unit that outputs a blank signal to the conversion apparatus, and a trigger signal output unit that outputs, to the conversion apparatus, a trigger signal to be converted into a vertical synchronization signal by the conversion apparatus.

Reduction in reproduction quality is suppressed in an imaging device that images a sound and a moving image. A frame rate converter converts a frame rate of a frame captured outside a predetermined period among a plurality of frames captured at a predetermined frame rate to a low frame rate lower than the predetermined frame rate. A duplication unit duplicates an original sound signal recorded over the predetermined period to generate a plurality of duplicated sound signals each of which is identical to the original sound signal. The audio signal processing unit performs different signal processing on each of the plurality of duplicated sound signals.

There is provided a video processing apparatus that includes a network interface, first and second video buffering sections, a video supply section, a video control section, and a command issue section. The two video buffering sections are configured to receive and store video data coming in packets over a network via the network interface. The video supply section is configured to supply a video signal to a video signal line, the video signal being a selected output from one of the first and second video buffering sections. The video control section is configured to execute control over the other components. The command issue section is configured to send a bus input change command to the video control section as an instruction for video data selection for supply to the video signal line, the bus input change command including information about identifying a video data supply source connected over the network.

Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.

A particular implementation for controlling single program transport streams during remultiplexing to a multiple program transport stream uses a series of leaky bucket buffers to minimize timing artifacts in the multi-program transport stream. Another implementation for controlling the remultiplexing process limits the number of consecutive packets to be transferred from each single program transport stream, or controls the multiplex frequency of each single program transport stream within the multi-program transport stream. An alternative implementation controls the remultiplexing process using multiple program clock reference values such that packets from each single program transport stream are released only after a previous program clock reference value is greater than the system time.

Methods and devices for presenting a virtual reality image may include rendering at least one image frame received from an application for a virtual reality image for display on a display device. The methods and devices may include receiving a selection of one of a plurality of tear thresholds that define conditions for tearing in a displayed image. The methods and devices may include determining whether the rendered frame is received prior to the selected one of the plurality of tear thresholds, wherein the selected one of the plurality of tear thresholds occurs after a frame timing event that corresponds to a deadline for initiating display of a new frame. The methods and device may include communicating the rendered image frame to the display device for presentation on the display device when the rendered frame is received prior to the selected one of the plurality of tear thresholds.

Provided is a control apparatus for an image pickup apparatus that can synchronize an image sensor with a frame period from an external device, such as a display apparatus, without use of any frame buffer, while optimizing the frequency of a clock signal used for the operation of the image sensor. An image sensor (11) receives a trigger signal from an external device (2), such as a display apparatus, and image data from an image sensor (11); calculates, for each frame, information of a time difference from the trigger signal to a time at which to start the output of the image data; and establishes, on the basis of the information of the time difference, a frame period of the image sensor (11) such that the time difference is accommodated within a given range, thereby allowing the image data to be supplied to the external device (2) within a given time difference relative to the trigger signal, though some degree of variation occurring in each frame.

A data processing method of a multimedia device is disclosed. The multimedia device pauses playback of multimedia data in response to a pause signal. The method includes: buffering the multimedia data before the pause signal is received to obtain prerecorded multimedia data; writing the prerecorded multimedia data into a storage unit in response to the pause signal; reading the prerecorded multimedia data from the storage unit in response to a playback signal; and playing the prerecorded multimedia data.
