The company's website embeds online live broadcast Aoku AVBox2010

1. Product Introduction

This is a portable device for live webcasting or recording and broadcasting. It is small and easy to use, and easy to carry. The product adopts single-board fanless structure design, built-in high-performance H.264 encoding chip, high-performance streaming media server, directly encodes the input 4 analog AV signals into streaming live broadcast signals, with the help of the built-in streaming media server or external streaming Media server, switch 1 channel to provide video live broadcast service.

4-channel live signal real-time coding switching output key operation, easy to use LCD screen to display working status

Beijing North Star Information Technology Co., Ltd.
The biggest highlight of AVBox 2010 is that it can encode two live streams with different bit rates at the same time, so that live streaming and recording can use different bit rates to achieve the best results; AOKU AVBox 2010 supports http protocol, RTMP protocol, with the help of FMS or Red5, etc. The streaming media server allows users to watch live content directly through the Flash plug-in without downloading the client; another highlight of AOKU AVBox 2010 is low latency, which is also the only option for low-latency live broadcast without downloading the client.

2. Performance characteristics

Pure hardware architecture, hardware coding method, optimized H.264 coding algorithm applied to high-performance multimedia processing DSP, live broadcast delay can be controlled at about 2 seconds; simultaneously collect 4 live broadcast signals, switch 1 signal in real time for FLV Encoded live broadcast; supports RTMP streaming media protocol, can push live broadcast streams to FMS, RED5 and other standard streaming media servers to achieve live broadcast; can also provide high-quality live streaming to third-party P2P servers; built-in high-performance streaming media server, using Http mode supports up to 16 clients to directly access AOKU AVBox 2010 to watch live broadcast, supports VLC Player, Storm Video, Windows Media Player and other players that support http access to directly watch live broadcast; supports PAL / NTSC collection standard, Support QCIF (176 × 144), CIF (352 × 288), 4CIF (704 × 576), D1 (720 × 576) mode to capture encoded video, support frame rate, key frame interval, encoding quality adjustment, etc. In the stepless adjustment, using QCIF mode, select 100kbps code stream, the video image is clear and process, 300kpbs can reach VCD quality, 700kpbs can reach DVD quality; image sound Clear and smooth, good synchronization; support live stream dual stream configuration, live stream and video can use different streams, to meet the best live broadcast and video effects; provide independent recording tools, you can set the recording task according to time, automatically on the live interface Recording, the recording format is standard ASF package, which can be cut, edited, transcoded by third-party tools; without downloading any plug-in, it can support Adobe Flash Media Player to directly access live video viewing; strong stability, guarantee system 7 × The need for 24 hours of uninterrupted live broadcast.
