Description
The GS1503B is a highly integrated, single chip solution for embedding/extracting digital audio streams into and out of high definition digital video signals. The GS1503B supports insertion/extraction of 24-bit synchronous audio data with a 48kHz sample rate. Audio signals with different sample rates may be converted to 48kHz by using audio sample rate converters before or after the GS1503B.
