Patent
Nextchip Co. | Date: 2017-01-11

A method and apparatus for exchanging a protocol is provided. A protocol may be indicated in a preset section of a vertical blanking interval (VBI) of an analog video and thereby transmitted. A protocol transmission apparatus may transmit an analog video signal in which a protocol signal is indicated to a protocol reception apparatus. The protocol reception apparatus may detect a protocol by receiving the analog video signal from the protocol transmission apparatus.


Patent
Nextchip Co. | Date: 2017-01-11

Provided is a method and apparatus for converting, to a digital video signal, an analog video signal capable of having a variety of resolutions. A video reception apparatus determines a format of an analog video signal by sampling the analog video signal. The video reception apparatus converts the analog video signal to a digital video signal based on the determined format. A comb filter is used to separate a color difference signal and a luminance signal from the digital video signal, and the digital video signal is reconfigured using the luminance signal and the color difference signal.


Patent
Nextchip Co. | Date: 2017-01-11

An analog video signal received through a cable may be distorted due to the cable and noise during its transmission. Provided is a method and apparatus for determining a level of transmission distortion and compensating for an analog video signal. A video signal reception method and apparatus may determine a distortion level of an analog video signal using an equalizing pattern signal included in a video signal, and may compensate for the analog video signal based on the distortion level.

Provided is a method and apparatus for transmitting a video signal. The video signal transmission method and apparatus receives a digital video signal from a video sensor, reconfigures the digital video signal by adaptively adjusting at least one of the number of horizontal blank samples and the number of vertical blank lines of the digital video signal so that the digital video signal corresponds to a video standard, converts the reconfigured digital video signal to an analog video signal, and transmits the analog video signal.
