Abstract:
The present invention relates to a proxy apparatus and a caching method thereof. The caching method of the proxy apparatus according to an embodiment of the present invention comprises the steps of: receiving a transmission request of content capable of being divided into a plurality of blocks from an external device, and indication information on a playback position of the content; if the transmission request is received, acquiring a header block including the header of the content; identifying a middle block corresponding to the playback position by using the header; if the identified middle block is not cached in the proxy device, requesting the middle block via a network; and transmitting at least a part of the header and at least a part of the middle block corresponding to the request to the external device. According to an embodiment of the present invention, an efficient caching method and system can be provided even through the size of the content is big but only a specific part is frequently used.

Abstract:
PURPOSE: A device and a method for providing an advertisement in consideration of content buffering time, thereby preventing a user from getting bored by the advertisement. CONSTITUTION: A calculation unit (220) calculates an expected buffering time for a content selected by a user. A selection unit (240) selects at least one advertisement corresponding to the expected buffering time calculated by the calculation unit. A providing unit (250) provides the advertisement selected by the selection unit.

Abstract:
PURPOSE: A cooperatives caching method and a device thereof are provided to cooperatively use a cache by composing a cluster between base stations connected with broadband links. CONSTITUTION: A control unit (730) determines whether request data from a client is stored in a cache. If the request data is not stored in the cache, the control unit requests the request data to a home base station predetermined to store the data. The control unit obtains the request data from a server or the home base station according to the storage of the request data in the home base station. The control unit services the request data to the client. [Reference numerals] (710) Interface unit; (720) Storage unit; (721) Cache; (723) Cooperation part; (724) Local part; (730) Control unit; (731) Required data determination unit; (732) Service providing unit
Abstract:
PURPOSE: A communication method using a heterogeneous protocol is provided to effectively embody one chip of heterogeneous protocol stacks by transmitting the data to an upper protocol stack. CONSTITUTION: A reception unit receives data from outside through a lower layer protocol stack which shares plural upper layer protocol stacks(1110). An analysis unit analyzes one or more broadcast function support methods of the upper layer protocol stacks, field values which displays kinds of the data, and the destination network ID(Identity) of the data(1120). A transmission unit transmits the data to one of the upper layer protocol stacks according to analysis results(1130).
