  • Patent number: 10165331
    Abstract: According to one exemplary embodiment, a method operable to store video data and/or audio data is adapted to a first peer of a video and audio data system having a plurality of peers, and each peer has a corresponding storage space. In the method, before the first peer has not received a service request of a second peer of the plurality of peers, determines whether the video and audio data received by the first peer is stored in its corresponding storage space with a dynamically adjustable first video and audio storing probability, and extends a time interval of the first peer for storing received video and audio data; and when the first peer receives the service request of the second peer, sets a second video and audio storing probability. Thereby the second peer obtains at least one stored video and audio data from the first peer.
