CPC Class H04N

A system and methods for upsampling of decompressed time-series data after lossy compression using a neural network that integrates AI-based techniques to enhance compression quality. It incorporates a novel AI deblocking network composed of recurrent layers for feature extraction and a channel-wise transformer with attention to capture complex inter-channel dependencies. The recurrent layers extract multi-dimensional features from the two or more correlated datasets, while the channel-wise transformer learns global inter-channel relationships. This hybrid approach addresses both local and global features, mitigating compression artifacts and improving decompressed data quality. The model's outputs enable effective data reconstruction, achieving advanced compression while preserving crucial information for accurate analysis.

The present specification relates to a transmission apparatus and method for transmitting a signal in a wireless AV system. The transmission apparatus measures a signal to interference plus noise ratio (SINR) in a radio link. The transmission apparatus selects a modulation and coding scheme (MCS) set on the basis of the measured SINR. The transmission apparatus selects an optimal MCS from among the MCS set on the basis of the priority of a signal. The transmission apparatus transmits the signal on the basis of the optimal MCS.

A centralized document system integrates online document execution and conferencing to control access to precipitant information. Precipitant information includes access codes, personal identification numbers, sensitive information, or any other secured information for which execution of an online document is a prerequisite for access to the secured information. The centralized document system detects precipitant information that is presented during a conference and controls access to the detected precipitant information (e.g., by generating permission rules that specify a type of online document to be executed to gain access). The centralized document system may determine whether a user has executed one or more online documents and thus, has authorization to access the detected precipitant information. Responsive to determining that the user has not executed the online documents, the centralized document system can control access to the precipitant information by modifying the conference (e.g., using censors or breakout rooms).

An actuator including a first circuit board on which an image sensor is disposed, a first housing disposed on the first circuit board, a lens assembly disposed within the first housing, and a second circuit board disposed on the first side portion of the first housing where a gyro sensor is disposed, and a third circuit board driving the lens assembly is provided. The third circuit board may include a first region disposed on the first side portion of the first housing and in which a first coil driving the lens assembly is disposed. The first coil may overlap the second circuit board in a direction perpendicular to an optical axis direction.
