Abstract: A new real-time video communication system includes a set of electronic devices. Each device runs a specialized real-time video communication software application including a video quality module. The video quality module retrieves network connection statistic data from a network connection module, and video encoder statistic data from a video quality module. The video quality module uses the network connection statistic data and the video encoder statistic data to determine a first objective video quality measure without extensive mathematical operations. The video quality module also uses the first objective video quality measure, the network connection statistic data and the video encoder statistic data to determine a second objective quality measure without extensive mathematical operations.

Abstract: The present invention relates to the field of soilless cultivation, in particular to a method for cultivating Mesembryanthemum crystallinum. The method involves the following steps: sowing; accelerating germination; growing seedlings; transplanting; separating seedlings; harvesting. In this method, Mesembryanthemum crystallinum is cultivated using a nutrient solution and under continuous indoor lighting; as a result, the Mesembryanthemum crystallinum has a shortened life cycle, no flowering period, and a long harvesting period. Edible salt is added to the nutrient solution at a specific ratio, which further promotes the growth of Mesembryanthemum crystallinum and changes its taste. Meanwhile, the nutrient solution of Mesembryanthemum crystallinum has a high EC, which promotes the growth of Mesembryanthemum crystallinum.
