Unlike other codecs that support ancillary data all data is split evenly between left and right channels to assure equal fidelity Direct ancillary data i e data that is not muxed with other data can be sent at bit rates up to 38 400 bps Muxed ancillary data can be up to 19 200 bps The ancillary data can be used for remote control of peripheral equipment at the far end for example tape recorders can be stopped and started using ancillary data Since the ancillary data is CDQ Prima s new low delay MPEG Layer 2 decoder yields 50 lower delay at any bit and sample rate for all single line connections coo rima USERS GUIDE sent in the audio bit stream the bits used for the ancillary data are not available for audio data Therefore it is not advisable to use a high ancillary data rate with a low transmission rate One key feature however is that if no ancillary data is present no bits are robbed from the audio data even if the cbqPrima is configured to send ancillary data Bandwidth is used only as needed cDQPrima 200 Series models can send two independent RS232 ancillary data streams The combined bit rate for both of the RS232 paths can not exceed the 19 200 bps maximum allowed by the multiplexer The cDQPrima s ancillary data features can even be used when connecting to other manufacturers codecs 1 6 4 Audio Compression The premier audio compression algorithm available in all cbgPrima Models and all other MU
