Digital radio receiver and method for providing digital radio

Abstract

The invention discloses a digital radio receiver and method for providing digital multimedia radio. The digital radio receiver provided by the present invention includes: a first decoder which decodes signals of a service A to output a plurality of first frames in a cross connecting area where the service A broadcasted at a first area and a service B broadcasted at a second area are received; a second decoder which decodes signals of the service B to output a plurality of second frames; a comparison part which compares the plurality of first frames and the plurality of second frames which are respectively stored in a first buffer part and a second buffer part to determine whether the first frames and the second frames are the same frames, determines the frame of the plurality of second frames which is continuous with a finally outputted frame of the plurality of first frames in time, when the cross connecting area transmits in a second area under a condition that the cross connecting area outputs the plurality of first frames one by one, and starts to output the plurality of second frames one by one from the continuous 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...

AI Technical Summary

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
