Abstract: A data object management method and a data object management system are provided. The data object management method includes the following steps. Generate a space allocation list according to an operation parameter of a space consuming device. The space allocation list records information about a plurality of storage spaces. Update the space allocation list and a target storage space. The target storage space is one of the storage spaces. Send a playlist corresponding to the space allocation list when a reading request corresponding to the space consuming device is received.

Abstract: A media streaming method and a device using the same are introduced herein. The disclosure introduces a method for smooth and flawless playback of live media streaming in dynamic network environment. When network congestion occurs for a period, a media receiver may play media data as more as possible by adjusting the transmission order of media data meaningful to the receiver or a provider for providing the media data. In one embodiment, the disclosure introduces a method for smooth and flawless playback of live media streaming by caching a certain amount of media data and then playing them at an appropriate speed to catch up to the progress of the live media streaming, or by dynamically changing bit rates of the live media streaming in time by the provider to meet the most acceptable bit rate according to the network environment between the provider and the receiver.

Abstract: A system for providing Video-on-Demand (VOD) service in a network includes a plurality of user devices and a server. Activation of an allowed transmission mode or a peer-to-peer transmission mode is dependent on whether a peer-to-peer transmission function of a first user device of the user devices is limited or not. The first user device calculates respective transmission rates of the two transmission modes to determine their respective download ranges. The transmission mode having a higher transmission speed downloads data close to a start of the target data and another transmission mode having a lower transmission speed downloads data close to an end of the target data. Based on the target data temporarily stored in other user devices, the first user device assigns each of the two transmission modes a download sequence of a plurality of clips of the target data to download the clips of the target data.

Abstract: Disclosed is a networked transmission system and method for stream data. The system comprises a network, a streaming server and an ordered series of a first up to n-th cooperative-sharing groups. There is a cooperative relationship among all users' terminals in a cooperative-sharing group. The streaming server provides a plurality of programs with stream data, each program being divided into one or more audio/video clips by a time-slot unit. The streaming server transmits the one or more audio/video clips to the leader node of the first cooperative-sharing groups. The leader node of each cooperative-sharing group transmits the currently received audio/video clip to the users' terminals within the same cooperative-sharing group, and passes the received audio/video clip to the leader node of the next cooperative-sharing group after one time slot.

Abstract: Communication devices and methods are proposed for providing communication channel. In one example, devices and methods are capable of reaching one or more terminals that are not in a public network. In addition, depending on the network or the networks that the terminals are located, some examples may be capable of establishing a less indirect or a direct communication channel between two terminals after they communicate through an intermediate system. In another example, a triggering packet may be sent to provide a binding at an interface of a private network, such as an NAT, thereby reducing or eliminating communication through a relay server.

Abstract: Disclosed is a system and method for transmitting streaming services. The system may comprise a service agent having a service list. The service list records the contact addresses and priority for one or more nodes that can provide streaming services. The priority for a node represents the level that the node belongs to a path for transmitting streaming data. When a client node requests the service agent for the nodes, wherein the nodes may provide a specific streaming service, the service agent searches for the service list and responds the search result to the client node. Therefore, the client node may get the streaming data directly from the nodes being found, and these nodes form a peer-to-peer network system.
