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.

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, conferencing, surveillance and streaming softwares and solutions over IP network for a whole series of commonly used digital media formats, including H.263, H.263-1998/2000, H.264/AVC and MPEG-4/Visual, with stream encapsulation methods of RTP (IETF standards) and MPEG-2 PS/TS (ISO/IEC/ETSI standands) well supported.

  • Real Time Video Transcoding

    • Besides transcoding abilities over varied video formats, IPVideoTrans product series provides methods for video stream reshaping, such as frame dimension switching (transsizing), frame rate altering and encoding bit rate up/down scaling (transrating).

    New since version 2.0: Audio transcoding is also supported, including PCM, MP2, MP3, MPEG-4/AAC, AMR-NB, etc.

  • Media Streaming & Broadcasting

    • IPVT's broadcasting server can stream media contents stored in disk files or network streaming servers (RTSP, RTMP) to clients through RTP, with transcoding on the fly.

  • Real Time Video Conferencing

    • By IPVT's video muxing/composing server product, live video conference of multiple users displayed in one split screen is easily achievable. Conference members' displaying order and layout can be customized at will in real time.

  • 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 Post Processing

    • Image overlay (logo/watermark) in mask or transparent mode, subtitle effects, etc. All can be applied during real time video transcoding or streaming on the fly.

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

According to performance of the PC box and attributes of the video stream to be processed such as encoding format, frame resolution and video quality, A desktop PC of usual performance (generic CPU @ 2~3GHz, single core) can run 20 to 30 real time transcoding channels concurrently, while a high end server like Intel Xeon® computer can run channels up to 80 or more.

Scenarios

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