Digital broadcasting receiving terminal and digital multimedia broadcasting providing method

Abstract

The invention discloses a digital broadcast receiving terminal and a digital multimedia broadcast providing method. The digital broadcast receiving terminal according to the present invention includes: a first decoder, which decodes the signal of service A in the handover area where service A broadcast in the first area and service B broadcast in the second area are simultaneously received. Output a plurality of first frames; a second decoder, decode the signal of the service B to output a plurality of second frames; and a comparison unit, compare the plurality of first frames stored in the first and second buffer units Compare with the second frame to confirm that it is the same frame. When the handover area outputs the plurality of first frames frame by frame, when handing over to the second area, the confirmation of the same frame is used. As a result, the last output frame of the plurality of first frames and the frames of the plurality of second frames that are temporally consecutive are confirmed, and the plurality of second frames are outputted frame by frame starting from the consecutive frames. In the second frame, the service A and service B are broadcasts with the same service ID.

Description

technical field [0001] The present invention relates to digital multimedia broadcasting, and more specifically relates to a digital broadcast receiving terminal capable of providing uninterrupted digital broadcasting and a method for providing digital multimedia broadcasting. Background technique [0002] Recently, analog broadcasting is in a trend of conversion to digital multimedia broadcasting (DMB). [0003] Generally, a digital broadcast receiving terminal continuously monitors other frequencies that provide the same broadcast when receiving one broadcast in order to provide seamless broadcast in a mobile environment. In addition, when the broadcast signal currently being received becomes weak, the same broadcast transmitted on another frequency is received through the handover area (Handover), thereby providing uninterrupted broadcast. [0004] For this, as figure 1 As shown, the digital broadcast receiving terminal is equipped with two RF parts, two baseband parts a...

Problems solved by technology

In this case, conventional digital broadcast receiving terminals cannot provide audio signals during the delay period (that is, cannot decode audio signals), so the problem of output interruption (muting phenomenon) often occurs
