Features

IO [io] 8000

MAYAH sets a new standard

for professional MPEG 4 audio

video solutions

IO [io] 8001 is a fully compliant MPEG 4 audio

video encoder for professional use, including

ISMA/RTP streaming and is fully up-to-date in

terms of audio video quality incorporating the

newest standards and protocols as well as high

tech encoder developments such as AAC+SBR.

IO [io] 8001 is a stand-alone 19" 2U high hard-

ware product which can be controlled by a

Windows Remote Software via IP, SNMP or a

Telnet interface. Easy control without a PC is

provided by the front panel keypad and a

graphical 128 x 64 LCD. Streaming to all

software players supporting MPEG 4 ISMA is

supported. Without display and keypad the IO

8000 model is ideal for remote controlled

applications.

IO [io] 8001 is an Audio Video Embedded Real-

time Solution and fully suitable for 24 hour 7

days operation due to its extremely and live

proven real-time operating system.

All levels of MPEG 4 simple profile and

advanced simple profile are supported by

MAYAH. Frames from 2 to 30 fps, image

resolutions from 16x16 to 720 x 576 (PAL),

Encoder/Decoder

The IO [io] 8000/8001 is capable of handling

audio-video encoding as well as audio-video

decoding as alternative function. All possible

parameters are controlled by the included

windows remote control software, Telnet or

SNMP management tools.

constant and variable bit rates from 5 kBit/s to

30 Mbit/s, de-interlacing, frame-rate conver-

sions and AAC audio encoding. It also supports

an easy to use graphical user interface.

Optimized delay

IO [io] 8000/8001 is capable of handling audio

video delay close to its optimum. Its implemen-

tation and the use of just one scalar processing

unit to replace several DSPs has resulted in

ultra-low delay times.

IO [io] 8001

MPEG-4 is the standard choice for digital

audio-video coding. MPEG-4 provides core

technologies for efficient storage, transmission

and manipulation of audio video data in

multimedia enviroments.

The standard has been developed by MPEG,

the Moving Pictures Experts Group of ISO,

which also already introduced MPEG-1 and

MPEG-2:

MPEG-1 for storage of audiovisual information

on CD-ROM at low bit-rates

MPEG-2 as generic coding of digital TV and

HDTV signals at higher bit-rates.

MPEG-4 is an open standard which is assumed

to cope with the requirements of multimedia

applications covering a wide range of, bit-

rates, resolutions, qualities and services. That

is why MPEG-4 is ideal for use in storage and

transmission systems.

Compared to exisiting standards like MPEG-1

and MPEG-2 or H.263, MPEG-4 offers much

better coding efficiency.

Possible applications of the MPEG-4 standard

are broadcast, internet video, interactive video

games, infotainment applications, interactive

storage media, content based image and

video databases, real-time video communica-

tions (videoconferencing, videophone),

mobile multimedia, digital television set-top

boxes, studio and TV (post-)production and

many others.

IO [io] 7000 is a combination of hard- and

software. The 19” 2U high hardware supports

professional audio/video interfacing, analog as

well as digital. Different to IO [io] 8000/8001

which is a realtime embedded solution, IO [io]

7000 hardware is controlled by a powerful

windows software application. It is the most

sophisticated real-time video encoding software

available today that delivers to you an easy-to-

use, fast and professional solution for MPEG-4

multicast streaming.

Whether for broadcast, security or monitoring

applications, IO [io] 7000 will satisfy the

requirements with its fully MPEG-4 and ISMA

compliance being integratable in nearly all

environments.

By supporting Live Capturing of analog and

digital sources, AVI files and MPEG 1 files to be

encoded into a fully compliant MP4 File or a

fully compliant multicast ISMA /RTP stream

(profile 0 and 1), IO [io] 7000 can be used for

real-time as well as production purposes.

It enables the transcoding of a variety of media

files to MPEG-4 files. Optionally, hint tracks for

ISMA compliant streaming can be added, as

well as live encoding of captured audio and

video.

It allows highly individualized parameter

settings to control video output in terms of

quality as well as bandwidth usage.

In connection with any ISMA compliant stream-

ing server, all content will reach all people

using ISO MPEG-4 or 3GPP players (such as

Apple’s QuickTime Player, Real Network’s

RealOne Player, Media Player with plugin, etc.)

The Multi-Decoder enables the decoding of up

to 4 MPEG-4 ISMA streams and can display

them within one screen.
