  • Publication number: 20090241146
    Abstract: An electronic programming guide (EPG) providing apparatus and method, in which an EPG is configured as a 3D form to facilitate a search for broadcasting program information included in the EPG. The EPG providing apparatus includes an EPG screen configuring unit and a control unit. The EPG screen configuring unit configures an EPG screen such that broadcasting program information is displayed on at least three faces of a 3D polyhedron. The control unit controls the EPG screen configuring unit to configure the BPG screen such that broadcasting program information corresponding to another broadcasting time zone or another broadcasting channel is displayed on the EPG screen based on a user input signal requesting a search for the broadcasting program information corresponding to another broadcasting time zone or another broadcasting channel.

  • Publication number: 20090158297
    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.

  • Publication number: 20080209008
    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.
