摘要： A channel switching method, a channel switching device, and a channel switching system are provided. The method includes that: a network buffer apparatus determines whether a buffered video stream burst in unicast is synchronous with a channel video stream pushed by a network node to a client in multicast; notifies the client of sending a request for joining a multicast group, so as to implement fast channel switching; and dynamically adjusts the speed of pushing the video stream in unicast, so that the number of concurrent connections of the client and the channel switching efficiency are increased, and the deployment and operation cost of an Internet Protocol Television (IPTV) system is decreased. In this case, the channel switching scheme achieves universality and expandability, and the level of user experience is improved.

摘要： The present disclosure relates to a comminution apparatus including a rotational reducing unit that is rotatable about an axis of rotation. The rotational reducing unit includes a plurality of material reducing components that are mounted to a carrier. The material reducing components are rotated by the carrier in a first direction about the axis of rotation. The comminution apparatus also includes a screen at least partially surrounding the rotational reducing unit. The screen defines a plurality of sizing slots that have slot lengths and slot widths. The slots are elongated along the slot lengths such that the slot lengths are longer than the slot widths.
