The present invention provides a method and a device for transmitting and receiving a broadcast signal for restoring a pulled-down signal. The method for transmitting the broadcast signal, according to one embodiment of the present invention, comprises the steps of: pulling video data down so as to reconfigure the same; encoding the reconfigured video data; encoding signaling information for the reconfigured video data; generating the broadcast signal including the encoded video data and the encoded signaling information; and transmitting the generated broadcast signal.

A method of digitizing an audio track carried on an elongate recording medium, such as a movie film, includes transporting the recording medium containing the audio track past a reader to enable sequential reading of the audio track. The reading of the audio track generates an analog output signal. The method also includes sensing a rate of transportation of the recording medium, and sampling the analog output signal at a sampling rate determined on the basis of the sensed rate of transportation to digitize the analog output signal. A system for digitizing audio is also disclosed.

A server in communication with a first device capable of receiving input from a camera attached to the first device, and a second device capable of displaying output, is provided. The server is configured to receive, from the first device, data relating to characteristics of the camera and characteristics of an image obtained by the camera of a screen of the second device; determine a screen pixel length of the screen; and provide instructions to the second device to display on the screen an object at a desired visual angle in response to the data received from the second device and the screen pixel length, while the first device is positioned at an arbitrary distance from the screen.

An information processing apparatus comprises a luminance value obtaining unit for respectively obtaining first and second luminance values of first and second captured images of a physical space, wherein the first and second captured images are respectively captured by first and second image capturing units; a parameter obtaining unit for respectively obtaining first and second tracking parameters of automatic exposure control corresponding to a change in brightness of the physical space for the first and second image capturing units; and a setting unit for setting a first image capturing parameter for the first image capturing unit based on the first luminance value and the obtained first tracking parameter and a second image capturing parameter for the second image capturing unit based on the second luminance value and the obtained second tracking parameter.

The invention relates to a device for an inspection system, in particular, to a sewer and pipe, respectively, inspection system comprising a rotation module, which is coupled to a pivoting housing, wherein the rotation module is rotatable about its longitudinal axis relatively to the pivoting housing, and wherein the rotation module comprises a slip ring for signal and energy transmission, respectively, between the rotation module and the pivoting housing.

Wearable glasses include a first capturer for photographing a front part, a second capturer for tracking a gaze direction of a user, and a controller for matching a target image captured by the first capturer with a three-dimensional (3D) interior map of a vehicle, corresponding to the target image, and determining a head direction of the user. The controller specifies an object corresponding to user gaze in the target image based on the determined head direction and the tracked gaze direction of the user. Accordingly, user convenience is enhanced.

A system for digitizing an image from an optical substrate having at least a first defect comprises a digital image capture device, a first light source positioned at a first position relative to the digital image capture device, and a second light source positioned at a second position relative to the digital image capture device. The second position is offset with respect to the first position. Light emitted from the first and second light sources are combined at a light receiving portion of the digital image capture device for causing the first defect to be nullified from a composite digital representation of the image that is generated using information outputted from the digital image capture device.
