IP Video Streaming Transcoding Conference Surveillance Solution At Low Cost


In the last few years, more and more applications of multimedia system have been deployed in telecommunication fields, both in circuit switched and packet switched networks. Since the delivery of digital media through broadband and wireless networks becomes feasible and popular, typically represented by 3G and VoIP technologies, communications among people from around the world are not only limited to speeches any more, but are extending to direct face-to-face vision. With the convergence of telecom and internet technologies and the devoloping of IP Multimedia Subsystem (IMS) and Next Generation Network (NGN), tremendous innovative multimedia applications like TV on mobile and live webcasting are coming forth every day.

an IMS Architecture

Among all these applications, inter-device media capability and reliability is always an important fact needs to take good care of. For there are now so many media formats of different standards of digital compression and transportation, such as G.7xx, AMR, H.26x, MPEG-4, and so on. Unfortunately, these formats are normally not fully but partially capable on our digital media devices like mobile phones, VoIP phones and handheld PCs. Two terminals with different media capabilities are like two men speaking different languages. They can't communicate with each other. For example, a 3G mobile phone of MPEG-4 capability will fail to establish a connection with another of H.263. In such case, video transcoding is a must.

Without Transcoding


IPVideoTrans (abbreviation "IPVT") provides real time video transcoding, surveillance and streaming software and solutions over IP network, supporting the whole series of commonly used digital media codecs, such as H.263(+), FLV, H.264/AVC, MPEG-4/Visual and MP3, AAC, encapsulated in RTMP, RTP (IETF standards) and MPEG-2 TS (ISO/IEC/ETSI standands) protocols.



The CPU / GPU computing performance and the video encoding profile decide the capacity of simultaneous transcoding / streaming. Video encoding profile includes video codecs, video resolution, image quality, frame rate & bit rate, etc. Roughly, a single computer with Intel uni-core desktop processor running @ 3GHz or same class is able to process 20-30 MPEG-4 streams of QVGA size simultaneously, while a high end server with Intel quad-core Xeon® processor can do 20-30 channels of H.264 standard definition.
