建構高畫質視訊服務於嵌入式系統 Technology
An embedded multipoint video mixer for PC based videoconferencing system is presented. The video mixer employs the embedded high quality media processor and connects to the PC based videoconferencing system with a PCI interface. This combination of embedded system and PC based open system can meet the requirements of real time and complexity of video processing in videoconferencing systems and also take advantage of open systems for multimedia and customized applications. The principle of the multipoint video mixer for videoconferencing systems is introduced. The realization of the video mixer based on H.264/VP8 standard is presented and the performance is analyzed.
SIP(session initial protocol) SDK
The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video and messaging applications. SIP is used for signaling and controlling multimedia communication sessions in applications of Internet telephony for voice and video calls, in private IP telephone systems, in instant messaging over Internet Protocol (IP) networks as well as mobile phone calling over LTE (VoLTE).
The protocol defines the specific format of messages exchanged and the sequence of communications for cooperation of the participants. SIP is a text-based protocol, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP).A call established with SIP may consist of multiple media streams, but no separate streams are required for applications, such as text messaging, that exchange data as payload in the SIP message.
