Abstract: A data input method of a NAND flash memory includes: determining whether a size of a writing-requested data is less than a reference value; calculating an error correction code (ECC) for the data using a software ECC method when the data size is less than the reference value; and writing the data and the ECC to a data region of the NAND flash memory. A data output method of the NAND flash memory includes: determining whether a size of a reading-requested data is less than a reference value; reading the data and an error correction code (ECC) from the NAND flash memory; calculating an ECC for the read data using a software ECC method when the data size is less than the reference value; and performing an error detection and correction by comparing the calculated ECC and the read ECC.

Abstract: Provided are a system and method for allocating a specific job or application to a specific slave core by using an inter-core-communication (ICC) channel and executing the job or application in a multicore system environment including the master core and a plurality of slave cores. The method of a master core, includes: initializing message transmission times; generating an event for processing a instruction received from an application program and generating a channel event message from the event; checking a process for transmitting the generated channel event message, and if a channel event message queue corresponding to an event transmitting request is not “FULL” of a previously-stored channel event message, transmitting the channel event message to a specific slave core to request for storing the channel event message; and returning a response of processing status to the request for storing the channel event message to the application program.

Abstract: Provided are a method and apparatus for receiving remote control key data in a home network and requesting a server to perform an operation corresponding to the remote control key data. The method includes converting the remote control key data to a code which can be referred to in a web document received from the server, determining an operation corresponding to the code by referring to the web document, and requesting the server to perform the determined operation. Accordingly, even when an item corresponding to a function supported by the server is not displayed on a menu screen, a user receiving a service from the server using a client device in the home network can use the function by instinctively pressing a remote control key corresponding to the function.

Abstract: Provided is a method of a media server providing broadcast content received from an outside source in a universal plug and play (UPnP) network. The method includes receiving a message from a control point requesting to change to a second channel, while transmitting broadcast content of a first channel by setting a connection for streaming with a media renderer; and transmitting the broadcast content of the second channel instead of the broadcast content of the predetermined first channel by changing a broadcasting reception of the first channel while maintaining the connection.
