Embodiments of the present disclosure relate to a method and device for NPRACH detect. In example embodiments, the method comprises determining whether an overlapping ratio between a first period and a second period exceeds a first threshold. A first NPRACH resource is available during the first period and a second NPRACH resource is available during the second period. The first NPRACH resource is associated with a first coverage level and the second NPRACH resource is associated with a second coverage level. The second coverage level is different from the first coverage level. The method also comprises in response to determining that the overlapping ratio exceeds the first threshold, determining a power estimation of noise based on a first plurality of signals received on the first PRACH resource and a second plurality of signals received on the second NPRACH resource. The method also comprises detecting existence of at least one random access preamble on the first NPRACH resource based on the power estimation of noise.

Method and device for NPRACH detection

The embodiments of the present application disclose a method and an apparatus for switching a bit stream type of a video presentation. The method comprises: determining a plurality of video presentations that have been started; determining a current split screen mode according to the number of the started video presentations; determining a bit stream type corresponding to the current split screen mode according to a preset correspondence between split screen modes and bit stream types; and switching a bit stream type of each started video presentation according to the determined bit stream type or bit stream types. The embodiments of the present application avoid a client from running out of memory and crashing.

Method and apparatus for switching bit stream type of video playing

Embodiments of the application disclose a method and apparatus for processing video playing, and relate to the technology field of video. The method includes: obtaining an adjustment instruction for a first video being played; determining whether the first video is being recorded; if the first video is being recorded, acquiring and storing a bit stream of the first video based on a current bit stream type of the first video. With the embodiment of the application, the complete recording of a video is ensured.
