Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.

Abstract: A method for aging and storage of Jiang-flavor raw liquor involves “growing, nourishing and storing.” The Jiang-flavor new liquors of different rounds are subjected to outdoor storage in jars for not more than 1 year, then the Jiang-flavor raw liquors of different rounds having experienced the outdoor storage in jars for not more than 1 year are blended and put into stainless steel tank for blending and aging for a period of 1 to 2 years, and finally the Jiang-flavor raw liquor having experiencing the blending and ageing in the stainless steel tank for 1 to 2 years undergoes indoor storage in jars for 2 to 10 years. The method combines different storage containers with different storage years, improving the aging and storage effect and the quality of the Jiang-flavor raw liquor in a targeted manner.

The integrated circuit includes a first and second memory modules, and an access signal determining module respectively connected to the first and second memory modules. The access signal determining module includes: an interface circuit for transmitting a first memory access signal of a processor to the first memory module; an address filtering circuit for determining a target safety level corresponding to an access address of the first memory access signal; and an access signal processing circuit for offsetting the access address of the first memory access signal in response to the target safety level being a preset level, obtaining a second memory access signal based on the offset address, and transmitting the second memory access signal to the second memory module. Thus, a lower-safety-level memory can be accessed by a higher-safety-level function.
