Digital television test stream generator, method thereof, and test stream recording medium using the same |
摘要 |
A DTV receiver test stream generator which prevents discontinuity phenomenon of a video and an audio, a method for generating the DTV receiver test stream, and a recording medium where the DTV test stream having no discontinuity phenomenon is recorded. To this end, a test stream for a function test or a performance valuation of the DTV receiver is generated and a reproduction time is equalized on the basis of the least common multiple of a video frame time, an audio frame time, and a TS packet time when the test stream is repeatedly reproduced. According to this, when used at a DTV production field where a test pattern is used or at a broadcasting system which repeatedly transmits the DTV stream of a limited length such as a stationary image, a reliability of the DTV receiver test can be ensured.
