Abstract

A DMB(Digital Multimedia Broadcasting) receiving apparatus and a method for measuring a recording time and a reproducing time in the DMB receiving apparatus are provided to more accurately measure the recording time and the reproducing time necessary for recording or reproducing a DMB audio / video signal by measuring the recording time and the reproducing time in each terminal in consideration of a receiving state of a transmission stream. A system decoder(10) decodes a DMB transmission stream, and outputs an AU(Access Unit) according to the decoded DMB transmission stream. An AU counter(40) counts the AU outputted from the system decoder(10). An A / V decoder(20) performs the A / V decoding of the AU outputted from the system decoder(10), parses the A / V decoded AU, and outputs an A / V frame according to the parsed AU. A frame counter(50) counts the A / V frame outputted from the A / V decoder(20).

Description

technical field [0001] The invention relates to digital multimedia broadcasting (DMB), in particular to a digital multimedia broadcasting (DMB) receiving device and a method for detecting recording time and playing time. Background technique [0002] Recently, the introduction and industrial application of digital multimedia broadcasting (hereinafter referred to as DMB) have gradually become clear. [0003] DMB is a digital multimedia broadcasting that has sound quality of CD (Compact Disk-high-density disk; hereinafter referred to as CD) level and can perform data / video services, and can provide excellent fixed and mobile reception quality. At the same time, according to the transmission device, it is divided into ground wave DMB using ground wave and satellite DMB using satellite. [0004] figure 1 It is a block diagram of a simple structure of a general digital multimedia broadcasting (DMB)-related receiving device in the prior art. Wherein, the above-mentioned receivi...
