Abstract: A refrigerator having a thawing device. The thawing device includes: a cavity, a device door, a radio frequency generator module, an upper electrode plate and a lower electrode plate, and a detection module, configured to detect an incident wave signal and a reflected wave signal of an electrical connection wire connecting the radio frequency generation module to the upper electrode plate, and calculate a load impedance of the radio frequency generation module according to a voltage and a current of the incident wave signal and a voltage and a current of the reflected wave signal to determine the thawing progress of the object to be processed.

Abstract: A thawing method for a thawing device includes: generating, by a radio frequency generation module, a radio frequency signal in a frequency range of 40 to 42 MHz; obtaining the radio frequency signal; and generating, by an upper electrode plate and a lower electrode plate, radio frequency waves of corresponding frequency in a thawing chamber according to the radio frequency signal, and thawing an object to be processed in the thawing chamber. Radio frequency waves using the above frequency range have shorter thawing time, higher temperature-uniformity and lower juice loss rate than radio frequency waves of other frequencies.

Abstract: In one embodiment, a method including receiving, by a server, an input video and extracting features of the input video to produce extracted features. The method also includes comparing the extracted features of the input video with metadata stored in a metadata database storage and incorporating the input video into a matched video corresponding to metadata that matches the extracted features of the input video upon determining that the extracted features of the input video match metadata in the metadata database storage.

Abstract: In one embodiment, a method of organizing multimedia content includes obtaining, by a server, a first video program. Also, the method includes selecting a first video, where the first video is a first subset of the first video program, and where the first video forms a first branch of the first video program and selecting a second video, where the second video is a second subset of the first video program. Additionally, the method includes selecting a first partial video, where the first partial video is a first subset of the first video and selecting a second partial video, where the second partial video is a second subset of the first video. The method also includes establishing a multi-dimensional index tree including a first video program level, a first video level, a first partial video level.
