Abstract

An apparatus for providing available codec information, includes a receiving unit that receives electronic program guide (EPG) data transmitted by a broadcasting operator; a codec-management unit that checks the position information of the codec based on the received EPG data, and manages the point of downloading time of the codec; an interface-generation unit that generates the position information of the checked codec, and provides the information to the EPG screen; and a display unit that displays the EPG screen including the position information of the codec.

Claims

1. An apparatus for providing available codec information, the apparatus comprising:

a receiving unit that receives electronic program guide (EPG) data transmitted by a broadcasting operator;

a codec-management unit that checks position information of a codec based on the EPG data received by the receiving unit, and manages a point of time of downloading of the codec;

an interface-generation unit that generates the position information of the codec, and provides the position information to an EPG screen; and

a display unit that displays the EPG screen including the position information of the codec.

2. The apparatus of claim 1, wherein the EPG data comprises a title of broadcasting content, a name of the codec that reproduces the broadcasting content, a downloading address of the codec, information about the codec, and available codec information that includes broadcasting content information.

3. The apparatus of claim 1, wherein the codec is included in a device within a home network or outside the home network.

4. The apparatus of claim 1, wherein the codec-management unit generates a searching message that checks whether the codec exists, and a codec-request message that requests the downloading of the codec, in order to check the position information of the codec.

5. A method of providing available codec information, the method comprising:

receiving electronic program guide (EPG) data transmitted by a broadcasting operator;

parsing the received EPG data and extracting codec information from the parsed EPG data;

checking position information of a codec based on the extracted codec information; and

providing the extracted codec information and the position information of the codec to an EPG screen.

6. The method of claim 5, wherein the EPG data comprises a title of broadcasting content, a name of the codec that reproduces the broadcasting content, a downloading address of the codec, information about the codec, and available codec information that includes broadcasting content information.

7. The method of claim 5, wherein the codec is included in a device within a home network or outside the home network.

8. The method of claim 5, wherein the providing the extracted codec information and the position information of the codec to the EPG screen comprises displaying a symbol indicating that the codec exists in a multimedia-reproduction device on the EPG screen if it is determined that the codec exists in a multimedia-reproduction device as a result of the checking the position information of the codec based on the extracted codec information.

9. The method of claim 6, further comprising:

broadcasting a searching message to search the codec to devices existing in a home network if it is determined that there is the codec does not exist in a multimedia-reproduction device as a result of the checking the position information of the codec based on the extracted codec information;

receiving a response message transmitted from a device existing in the home network that received the broadcast searching message; and

determining the position of the codec as within the home network based on the response message,

wherein the providing the extracted codec information and the position information of the codec to the EPG screen comprises displaying information indicating that the codec is in the device in the home network on the EPG screen.

10. The method of claim 9, further comprising:

determining the position of the codec as not being within the home network if the response message is not received from the device existing in the home network,

wherein the providing the extracted codec information and the position information of the codec to the EPG screen comprises displaying information indicating that the codes in not within the home network on the EPG screen.

11. The method of claim 5, further comprising:

checking a point of time and a period of downloading of the codec; and

requesting the downloading of the codec based on the point of time and the period of the downloading of the codec.
