Abstract: A method and an apparatus for processing video and audio data received in a decoding system are provided. The method includes the following steps. When a program clock reference (PCR) is unavailable in the system, a system time clock (STC) is recovered by using a presentation time stamp (PTS) of video or audio data, or a linear combination result of the PTS of the video data and the PTS of the audio data.

When a broadcast signal is stored, it is stored together with the electric field strength, thereof. When the stored broadcast signal is reproduced, block noise, of a screen is efficiently removed by applying an MPEG, noise reduction value corresponding to the electric field strength of the stored broadcast signal to the stored broadcast signal. Therefore it is possible to improve the definition of the screen.

Abstract: A computing system that has access to a streamed multimedia sample that is stored on a storage medium applies a zero-based presentation timestamp numbering scheme to the data packets of the multimedia sample, on-the-fly, and after each seek operation.

Abstract: A method and apparatus for receiving and recording a digital broadcast program and reproducing a recorded digital broadcast program with time-based trick play features. While recording a broadcast program on a storage medium, the apparatus creates an index file regarding random access points of the program.
