An image-displaying device includes an image output section, an image data generation section, and a display section. The image output section outputs output data corresponding to an image of a subject. The image data generation section converts the output data to image data by each line and converts image data of a line in a first period. The display section displays the image data of the line in a horizontal synchronization period of the display section. The first period is shorter than the horizontal synchronization period.

A signal processing apparatus, signal processing method, program, and signal transmission system can transmit 8K or 4K video signals stably through a device of 100 Gbps. A signal processor includes a mapping unit configured to map an 8K or 4K video signal onto first data streams, prescribed by a predetermined format, of plural channels, and a multiplexer configured to generate plural first data blocks by scrambling the first data streams of either odd-numbered or even-numbered channels, first bits by first bits, invert the polarity of data blocks which are part of the first data blocks, generate plural second data blocks by 8B/10B-converting the first data streams of the other channels, second bits by second bits, and generate serial second data streams of plural lanes by multiplexing the first data blocks and the second data blocks. The processor is applicable to a broadcasting camera, for example.

An object of the present disclosure is to reduce a delay time until a specific video input is output at the time of inputting a plurality of asynchronous video images and synthesizing the images.

The present disclosure is an apparatus for synthesizing a plurality of asynchronously input video signals into a video signal displayed on one screen, wherein the plurality of video signals are synthesized such that a delay of a video signal of a pivot input set among the plurality of video signals is reduced.

Disclosed is an audio watermark insertion method. The audio watermark insertion method includes performing a modulated complex lapped transform (MCLT) on a first audio signal, inserting a bit string of a watermark in the first audio signal obtained by performing the MCLT, performing an inverse modified discrete cosine transform (IMDCT) on the first audio signal in which the bit string is inserted, and obtaining a second audio signal, which is the first audio signal in which the watermark is inserted, by performing an overlap-add on a signal obtained by performing the IMDCT and a neighbor frame signal.

An original image layer is mixed with one or more graphics layers to form a composite video signal, such as in a vision mixer. Also, the same graphics layers are mixed identically into another, known background image layer to give a second composite video signal. The currently applied added graphics layers are determined, without directly accessing the added graphics layers themselves, using only the first and second composite video signals, the original image layer, and the known background image, such as in a graphics layer detection device. A triangulation matting algorithm may be used in one example.

A VLC signal representing an alignment identifier is detected by cameras (4) of multiple user devices (1, 2, 3) filming a scene. Encoded video frames (91, 92, 93) from the user devices (1, 2, 3) are decoded and light patterns representing the captured VLC signal are identified in at least some of the video frames following decoding. The light patterns are decoded into alignment identifiers that are used in order to time align video frames (91, 92, 93) from different user devices (1, 2, 3) to thereby achieve video frame synchronization of video data from multiple user devices (1, 2, 3) recording a scene. The embodiments thereby enable video frame synchronization without the need for accurate clock synchronization between the user devices (1, 2, 3) and a video synchronization system (10).

A method and apparatus for synchronizing data captured by multiple image and non-image data capture devices using timing information. In one embodiment, the device comprises a plurality of interfaces operable to receive streaming data from each of a plurality of image and non-image capture devices and timestamping logic implemented, at least in part, in hardware and coupled to the plurality of interfaces to generate and assign timestamp information to each set of data captured by individual capture devices of the plurality of image and non-image capture devices to indicate when the data was captured, where the timestamp information is synchronized to a single timestamp reference clock. The device also comprises processing logic coupled to the timestamping logic to group image data from image capture devices with data from non-image capture devices using the timestamp information.

An AV device including a first signal transmitter configured to output a video signal and a first audio signal corresponding to the video signal to a display device; a first signal receiver configured to receive a feedback signal of the first audio signal from the display device; a second signal transmitter configured to output a second audio signal corresponding to the video signal; and a controller configured to determine a processing delay time of the display device by comparing the first audio signal and the feedback signal, and control the second signal transmitter to delay the output of the second audio signal based on the determined processing delay time.

An image-displaying device includes an image output section, an image data generation section, and a display section. The image output section outputs output data corresponding to an image of a subject. The image data generation section converts the output data to image data by each line and converts image data of a line in a first period. The display section displays the image data of the line in a horizontal synchronization period of the display section. The first period is shorter than the horizontal synchronization period.
