Although music program data has been recorded on a disc, imperfect index data or a signal has been recorded so that music program data is prohibited from being reproduced. To allow music program data to be reproduced, the index data is rewritten to perfect index data or a permission signal that allows music program data to be reproduced is transmitted through a communication line. Thus, music program data can be reproduced from the disc. Since music program data is not directly transmitted, the data transmission time is shortened. The music program data can be downloaded at high speed. In addition, the charging process can be smoothly performed. Moreover, music program data can be prevented from being illegally used.

The multicast router based on package and circuit switching technology is characterized by being applied to a network on chip which includes a plurality of multicast routers, a plurality of resource nodes and a plurality of interconnection channels; each multicast router comprises an input state machine module, a priority encoder module, a decoder module, an address filtering module, an arbiter module, a crossbar module and an output state machine module; in a multicast data transmission event, a single requester node can simultaneously support sending the same batch of data to at most eight target nodes at the same time; and the success rate of establishing a link can be improved by the priority encoder module, and the target nodes are prevented from repeatedly routing by the address filtering module. The multicast router based on package and circuit switching technology can fully utilize the parallelism characteristic of the network on chip to save time consumed for the event of sending the same batch of data to the plurality of target nodes by the single requester node, and consumption on cache resources of the multicast routers in the network on chip is reduced.

The present invention relates to data communication system and method enabling the utilization of contents by accessing the wireless Internet through self-formation of a dynamic URL by the caller's terminal application. When the caller attempts a voice call or a data call, the contents menu list registered by the receiver (or contents provider) and the caller/receiver information are transferred to the caller's terminal through a paging channel. Then, an application software stored in the caller's terminal processes the service option and displays the menu based on the menu list and caller/receiver information. Subsequently, in response to the caller's menu utilization request, a dynamic URL is formed from the combination of the identification number and contents type of the menu selected by the caller and the caller/receiver information.

A dual buffer memory system capable of improving system performance by reducing a data transmission time and a control method thereof are provided. The dual buffer memory system includes a flash memory block and a plurality of buffers. The dual buffer memory system uses a dual buffering scheme in which one buffer among the plurality of buffers interacts with the flash memory block and simultaneously a different buffer among the plurality of buffers interacts with a host. Therefore, it is possible to reduce a data transmission time between the flash memory and the host, thereby improving system performance.

The invention provides a resource dispatching method and a system based on a wireless system, applied to a multi-hop network, and the specific realization method is: a bandwidth is given to MS by a mobile terminal MS synchronous station, and data are transmitted to the synchronous station of MS through the acquired bandwidth by MS; data is transmitted to an upper node through the bandwidth given by the upper node from each level of nodes between MS and MMR-BS supporting a mobile multi-hop relay station, after a bandwidth given by the upper node is acquired between a lower node given by the bandwidth and the data received from the lower node and data of the lower node are received. The invention has the advantages that the application of the scheme can assure the acquirement of the bandwidth before receiving the transmitted data from the lower node; the space between the acquired bandwidth and the received transmission data is relatively small; not only can the whole data transmission time be effectively compressed, but also the distributed bandwidth is in line with the real-time condition of a link of the network; a problem of disabled bandwidth distribution can be effectively avoided.
