METHODS AND SYSTEMS FOR MANAGING STORAGE OF VIDEOS IN A STORAGE DEVICE

Systems and methods for storing videos in a storage device, more specifically in a digital video recorder (DVR). The method includes determining, for each video, a condition indicating a need to reduce the size of a respective video is determined. The condition being at least a storage period of the respective video being greater than a threshold time period. Upon determination reducing the video size either by reducing at least one quality parameter of the respective video or by eliminating at least one video segment of the video corresponding to an uneventful region. Further after the size reduction, storing the respective video as a modified version of the respective video in the storage device. Further, the video or a portion of video comprising important events can be shared with a remote device.

SIGNAL PROCESSING DEVICE AND VIDEO DISPLAY DEVICE COMPRISING SAME

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

A method for preventing forgery of data according to an embodiment includes determining a noise level based on metadata of original data, generating noise by applying the determined noise level to a preset noise pattern, generating transformed data of the original data by adding the generated noise to the original data, and transmitting the transformed data and the metadata to a server.

Automatic annotation of video quality impairment training data for generating machine learning models of video quality prediction

Exemplary embodiments are directed to methods and systems for annotating generating training data for video quality impairment detection. A video stream recorder extracts one or more image frames from a reference video stream as it is played. A video image labeler embeds a unique label into each of the one or more extracted image frames. The video stream recorder records the one or more labeled image frames as a labeled video stream. The video stream player then plays the labeled video stream through an impaired communication channel to generate a degraded video stream. A video image comparator compares one or more corresponding frames of the labeled video stream and the degraded video stream to generate one or more difference frames. An impaired image recorder annotates at least one of the one or more difference frames according to a corrupted region of the at least one difference frame.
