Abstract:
PURPOSE: An ATM firewall switch device with a call admission control structure and a parallel cell screen structure and a method therefor are provided to minimize the deterioration of an ATM switch and delay of a cell processing time when adopting a virtual connection or packet level security policy. CONSTITUTION: A signal cell filter(200) extracts a signal cell from cells introduced into a screened input unit(102). A management cell filter(201) extracts a management cell from cells which have passed the signal cell filter(200). A parallel cell screen unit(202) reduces a cell processing time delay according to a screen policy application. A header converter(205) adds switch information to a user cell which has passed the parallel cell screen unit(202), and outputs it to a cell switching unit(104). A VP(Virtual Path)/VC(Virtual Connection) table(206) stores allocated VPI(Virtual Path Indicator)/VCI(Virtual Connection Indicator) information and policy information on a virtual line. A security policy cash(207) is referred to determine a security policy. A cell duplicator(203) duplicates introduced user cell as many as the user cell filters(204) and transfers it to a cell filter(204). The user cell filter(204) filters only the cells allocated to itself by referring a VPI(Virtual Path Indicator).

Abstract:
The present specification provides a method and an apparatus for reproducing immersive media for a mobile equipment environment. According to the present specification, a mobile terminal for reproducing immersive media includes: an immersive media storage unit which stores an immersive media file; an immersive media analysis unit which loads the immersive media file, analyzes the immersive media file, and divides the immersive media file into video, audio, and immersive effect metadata; a media display which displays the video or the audio; a metadata parser which parses the divided immersive effect metadata; a metadata mapping unit which maps the parsed immersive effect metadata by immersive effects; a device synchronization control unit which adjusts the time synchronization of the immersive effect metadata to the time synchronization of the video or the audio; and a device control information transmitting unit which transmits, to an immersive media reproducing apparatus, control information including the time synchronization information of the immersive effect metadata and the mapping information of the immersive effect metadata.
Abstract:
PURPOSE: A context-aware transmission control device and a controlling method thereof are provided to reduce the use of fuel by the operation of an engine brake of a vehicle by changing an accelerator and a brake into a neutral advance control mode. CONSTITUTION: A context-aware transmission control device comprises the following: a vehicle driving unit supplying context-aware information; and a context-aware transmission control unit(102) controlling the vehicle driving unit to operate a neutral advance control mode when an accelerator(108) and a brake(110) is turned off by the context-aware information including speed meter information, accelerator information, and brake information. The context-aware transmission control unit is also controls the vehicle driving unit to operate a normal mode when the speed is slower than the reference speed.
