Patent ID: 7715827

Claim:
A mobile communication terminal comprising: a communication unit configured to download a media file from a media server; a controller configured to generate a table indicating a data-size-per-time using information extracted from the media file, measure a data size of currently downloaded data among the media file, and determine a media play time corresponding to the measured data size of the currently downloaded data using the generated table, wherein the extracted information includes a duration, a timescale, a sample count, and a sample size; and a display unit configured to display the determined media play time of the currently downloaded data file, wherein the controller: divides the duration by the timescale to arrive at a total running time, divides the sample count by the total running time to arrive at the sample-count-per-time, and sequentially adds up the sample size of each sample-count-per-time to arrive at the data-size-per-time, and wherein the sample size and the sample-count-per-time are acquired from the extracted information.
