IP Video Solution At Low Cost Streaming, Transcoding, Conferencing, Surveillance...

Introduction

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

Products

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.

  • Real Time Video Transcoding

    IPVT's transcoding server can stream media contents from disk movie clips or media streaming servers (Windows Media Service, Flash Media Server, Wowza Media Server) to clients through RTMP or RTP, with transcoding on the fly. Besides transcoding abilities over varied video formats, IPVTL provides methods for video stream reshaping, such as frame dimension switching (transsizing), frame rate altering and encoding bit rate up/down scaling (transrating).

  • Real Time Video Surveillance

    IPVideoTrans provides video server product to capture live video from video input devices, such as web cameras and digital camcorders. Live video is encoded into Adobe Shockwave Flash (SWF) objects or RTSP streams, which can then be published to internet visitors through HTTP or RTSP protocols.

  • Real Time Video Conference

    A P2P video chat and sharing system with high efficiency, that enables users to communicate with 15 friends max from around the globe at the same time. You can have video chat with your friends, share your favorite pictures and videos and even your desktop.

Benefits

  • Low cost, Easy Configuation & Maintenance

    Compared with other hardware video processing devices costly to deploy and maintain, IPVT's products are software programs that can be run on any PC box, in both Windows and Linux operating systems. With simple program configuration and easy interface, new users can create transcoding or other jobs on demand in less than ONE minute.

  • High Integrability

    Besides software products ready to use, IPVT provides full SDK on media stream processing. Functions like transcoding and video conferencing can be rapidly integrated by 3rd manufactures or developers into their own production.

Scalability

CPU performance and video encoding profile decide the capability of simultaneous streaming on a PC box. Video encoding profile includes codec being used, video resolution, image quality, frame rate & bit rate, etc. Generally, a desktop PC with Intel single core CPU @ 2~3GHz or same class can handle 20 to 30 MPEG-4 streams of QVGA size simultaneously, while a high end server with Intel Quad-Core Xeon® can handle 20 to 30 H.264 streams of standard definition.

Scenarios

IPVideoTrans's products typically apply to:
  • 3G-324M / VoIP Media Gateways
  • IP-PBX / Soft Switches / Media Proxy Servers
  • IPTV STBs and Other Media Streaming / Broadcasting Services
  • Video Monitoring / Surveillance
  • Live Webcasting
  • Web Based Video Conference
