To achieve CD quality (16bit/44.1khz stereo) need 1411.2 kbit/s bandwidth, obviously Bluetooth A2DP cannot allow (Bluetooth 2.0/2.1 + EDR The largest carrier rate is about 2.1mbit/s, minus the protocol header, interference, power dissipation factor influence , the actual maximum transfer rate is approximately 1000bit/s), so the audio data needs to be compressed. We know that the same bit rate, different encoding format compression rate is different, thus decoding the quality of the restoration i

Session Border controller (SBC) is a standard configuration product for NGN and IMS networks.SBC is generally located between two service provider networks in a peer environment, or between an access network and a backbone network that provides services to residents and enterprise users. Although some SBC only process signaling, m

The basic idea of the Subband encoding (Subband CODING,SBC) is to use a set of Bandpass filters (Band-pass FILTER,BPF) to divide the frequency band of the input audio signal into several successive bands, each of which is called a subband. A separate coding scheme is used to encode the audio signals in each sub-band. When transmitting on a channel, the code of each child band is composited together. At the receiving end of decoding, the code of each

, as the midcom protocol matures and develops, it is expected to gain more and more application prospects. The use of midcom requires upgrading existing equipment. STUN (Simple Traversalof UDP Through Network) IETF RFC 3489 defines how to determine the public address and port assigned by NAT and does not need to transform an existing NAT. Main Features: ?? Enables the client to discover the existence and type of NAT; ?? Enables the client to discover the binding life cycle of NAT; ?? Can work in
