While the 32 kHz sampling frequency is still provided for in the MPEG standard, it is in fact obsolete. A sampling rate of 48 kHz at 16 bit resolution yields a data rate of 786 kbit/s per channel, which means approx. 1.5 Mbit/s for a stereo signal.作者: 很像弓] 時間: 2025-3-25 13:34 作者: 鐵砧 時間: 2025-3-25 16:17 作者: Aspirin 時間: 2025-3-25 22:24 作者: Endemic 時間: 2025-3-26 04:01
Teletext Transmission to DVB, with a 3-byte start code (00 00 01). This is followed by the stream ID OxBD, which corresponds to a “Private_Stream 1”.
