Description

The Suprima LC is an affordable, multi-algorithm IP stereo audio codec offering a subset of the features of the Suprima.      

The Suprima LC supports many popular coding algorithms including G722, MPEG1/2 Layer II, MPEG1/2 Layer III and uncompressed linear audio (PCM). Other compression modes can be offered as an option. Each Suprima LC fully supports IP (TCP and UDP), terminated with a 10BaseT/100Base-TX Ethernet port (RJ45 connector). This enables remote monitoring/configuring and data/audio transportation over data communication links (LAN, Wan, Internet…).

Streaming advance features:

• Jitter correction buffer. This adjustable buffer avoids audio dropouts compensating for up to 10 seconds of jitter in the IP connection.

• The unit automatically adjusts in synchronisation with the transmitter site rate, to give a constant delay in IP communications.

• The frame size is user configurable, to give full flexibility when adjusting the delay and bandwidth use.

• The codec provides a test tool which allows the user to check the bandwidth, delay and jitter in the IP connection. This information can be used to adjust the streaming parameters and so, to obtain the best-quality in the real-time audio reception.

s includes the SP-201, SP-230, SP-201sa.
