SBC, or low-complexity subband codec, is an audio subband codec specified by the Bluetooth Special Interest Group (SIG) for the Advanced Audio Distribution Profile (A2DP). [1] SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers.
In many cases the SBC hides the network topology and protects the service provider or enterprise packet networks. The SBC terminates an inbound call and initiates the second call leg to the destination party. In technical terms, when used with the SIP protocol, this defines a back-to-back user agent (B2BUA). The effect of this behavior is that ...
NAT traversal with SBC during user registration. Similar to the registration case, the SBC will also include itself in the path of INVITE and other request messages. When receiving an INVITE from a user agent behind a NAT, the SBC will include a via header with its own address, replace the information in the contact header with its own address and also replace the address information in the ...

Epidemic routing [6] is flooding-based in nature, as nodes continuously replicate and transmit messages to newly discovered contacts that do not already possess a copy of the message. In the most simple case, epidemic routing is flooding; however, more sophisticated techniques can be used to limit the number of message transfers.
The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a standardised architectural framework for delivering IP multimedia services. Historically, mobile phones have provided voice call services over a circuit-switched-style network, rather than strictly over an IP packet-switched network.

A DDC consists of three subcomponents: a direct digital synthesizer (DDS), a low-pass filter (LPF), and a downsampler (which may be integrated into the low-pass filter). DDC block diagram. The DDS generates a complex sinusoid at the intermediate frequency (IF). Multiplication of the DDS frequency with the input signal creates images centered at ...
