Abstract: In some embodiments, a method sends a set of first requests for a set of first segments of a video in a playback session. A first protocol from a plurality of protocols is specified in at least one of the set of first requests. The set of first segments is received. The method determines whether to switch from using the first protocol to a second protocol in the playback session based on receiving the set of first segments. When switching to the second protocol, the method sends a second request in the playback session, wherein the second request indicates the second protocol is to be used to send a second segment of the video.

Abstract: The present invention provides a method for increasing wheat yield and preventing wheat diseases and use thereof, and relates to the technical field of crop cultivation. In the method, wheat seeds are primed by a fermentation liquid of S. sclerotiorum, and the concentration of the fermentation liquid is 1.4×105 cfu/mL or more. According to the present invention, the wheat seeds are primed by using S. sclerotiorum, and S. sclerotiorum can endogenously grow in wheat plants to induce expression of genes related to disease resistance and development of wheat, thereby achieving the objective of controlling diseases such as wheat Fusarium head blight and improving wheat yield.
