Terminal and Method for Providing Seamless Channel Change Function

The present invention relates to a device and method for providing a seamless channel switching. The present invention relates to a mobile communication terminal including a key input unit, a display unit and a wireless circuit section, when said mobile communication terminal provides a streaming broadcast services to the device user to connect to the streaming broadcast service server, general buffer (Current Buffer) and a memory including a temporary buffer (Temporal buffer); And the terminal user is assigned to the temporary buffer to the second channel in the first stream, and the non-view channel broadcast data by assigning the common buffer to the first channel being watched (未 視 廳), and of the second channel but periodically updates the non-viewed channel broadcast data, in a second channel stores the viewing channel stop the stream of the first and when changing to the second channel, the first channel broadcast data in the first channel and in the temporary buffer US after at the same time as playing the last-watched channel broadcast data by assigning the common buffer to the second channel and buffers the second channel broadcast data, it completed the buffering of the second channel broadcast data broadcast non-viewing channel of the second channel seamless channel, characterized in that it comprises a control unit for performing control for streaming in connection with the time to end the reproduction of the data It provides a device for providing a ring function. According to the present invention, while playing back the broadcast data stored in advance in the temporary buffer in the other channel when changing from a channel being currently viewed to another channel, and then buffering the broadcast data to a common buffer of the other channel, the broadcast data of other channels, since the stream, without the wait time that occurs in the prior art caused by the buffering of the changed channel when the channel change of the streaming broadcast, there is an effect that it is possible to do this, a seamless channel switching when changing a channel through. Seamless, streaming channels, change the buffer
