Abstract: An apparatus and a method capable of receiving digital broadcasting without image discontinuity during channel switching. A digital multimedia broadcasting receiver buffers a previous channel while a new channel is buffered in a deinterleaver, thereby preventing image discontinuity during channel switching. The digital broadcasting receiver receives and deinterleaves broadcast data of a channel to be changed and stores the deinterleaved broadcast data in a buffer when a broadcast channel change is requested. The digital broadcasting receiver outputs and displays broadcast data of an initial channel stored in the buffer and stops output of the broadcast data of the initial channel and outputs the broadcast data of the channel to be changed, when the broadcast data of the channel to be changed are stored in the buffer by a predetermined buffering size.

Abstract: Disclosed is a method for providing location information of a terminal by using an Session Initiation Protocol (SIP). To this end, a location request and a location estimate are transferred between terminals by using messages used in the SIP. In particular, it is possible to receive location information of a counterpart during communication, or transfer the location information of its own to a counterpart, in consideration of the fact that real-time voice service mainly uses the SIP. Moreover, it is possible to request and transmit location information on using multimedia services. Therefore, a terminal or a server using the SIP easily uses location information, so that it is possible to provide new services inter-working with location services.
