Description

Access device and remote controller

technical field

The utility model relates to the field of network technology, in particular to an access device and a remote controller.

Background technique

Voice over IP (VoIP, Voice over IP) can be translated as the transmission of voice signals through an IP network, so VoIP is a network communication technology that can realize voice communication on an IP network.

Carrying out voice communication through the Internet is a very complex system engineering involving many technologies, the most critical of which is VoIP technology. The following introduces the basic principles of VoIP and related technical issues.

The traditional telephone network transmits voice in circuit switching mode, and the required transmission bandwidth is 64kbit/s. VoIP, on the other hand, uses the IP packet interaction network as the transmission platform, and performs a series of technical processing such as compression and packaging on the analog voice signal, so that it can be transmitted through the connectionless UDP protocol.

In order to transmit voice signals over an IP network, certain elements and functions are required. In its simplest form, a network consists of two VoIP-enabled devices connected by an IP network. For the basic structure of the VoIP model, please refer to Figure 1. From the figure, it can be seen how the VoIP device converts the voice signal into an IP data stream, and transmits it to the IP destination through the IP network, and the device at the IP destination converts it back to voice signal. The network between the two must support IP transmission, which can be any combination of IP routers and network links; the VoIP transmission process can be roughly divided into the following stages: analog voice signal conversion into audio data; audio data Conversion to IP packets; transmission process; conversion of IP packets to audio data; conversion of audio data to analog signals.

In recent years, with the development of VoIP technology, people increasingly hope to integrate VoIP functions into existing interactive systems, for example, integrated into IPTV set-top boxes, home gateways, video conferencing terminals and other access devices, so as to realize While using VoIP technology to communicate with remote parties, interactive operations can be performed with the access device; and a remote control can be used to easily establish/cancel VoIP calls without affecting access to the device. control operation.
