DVMixer Pro Overview
     
This overview describes GAPsoft stream software application allowing you to easily capture, edit, encode and deliver your streaming media.
DVMixer Pro¢â is an integrated streaming video encoding/decoding solution, which supports analog, digital and stream input, and enables real time caption/logo insertion and transition effects with 5 input video sources simultaneously. Also scheduling functionality, such as one available on the existing media server, is available in the encoder, which serves as a strong utility for live and on-demand editing.
 
 
Multi-video source mixing and switching, encoding/decoding, caption generating and scheduling all in one DVMixer¢â is what makes a powerful and cutting-edge solution for professional streaming video out. In addition, supporting WMT - Microsoft streaming core technology standard, Real Media, ISO-MPEG4 - the 3G video standard and MPEG2 - digital TV standard, is what makes the solution truly remarkable.
 
This fully software product is designed to meet based in real time for professional quality, high performance at various sample rates and sizes for multiple video industry standards - Windows Media Video, Real Media Video, MPEG1 & 2, Quick time and ISO-MPEG4 and multiple physical types - stored video source in hard drive and files over the network, and captured video source from camcorder/VTR - in the1) Decode/Encode part.
2) Transition part with FX effects is function to switch multi-video sources - maximum 5 input video sources simultaneously - both to live stream out and save for on-demand playback at a later time. 3) Graphics & Titles part based on text, image and animation provides real time caption, subtitle, logo and ad insertion features and number of options for multiple mode. 4) Scheduler part is for scheduling the input/output streams by time.

High performance dual processor based, for very high processing power, to run multiple video source encoding, switching outputs, effects, and Graphics & Titles tasks on one software system.
 
 
The background technology identifies and characterizes the components, interfaces, and protocols. This includes the streaming video/audio decoding/encoding/trans-coding, multi source transition, digital effects and insertion functions that enable input video source and objects to communicate in a distributed environment, and three categories of interfaces:
 
  • Multiple video sources as of Windows Media Video (ASF), Real Media, DV, AVI, and MPEG1 & 2 files real time Encode/Trans-code to WMV (ASF), RM, Quick time and MPEG4 files and re-delivery the video source.
  • Transition effects & insertion functions - caption, title, ad, and logo in text, image and animation basis insertion
  • Remote controllable based on the network protocol and FIREWIRE (i.LINK)
Streaming Live Content
Do you want to cover a live event, such as a concert, sports game, distance learning, corporate training, corporate meeting, and other public events, and deliver it over the Internet or an Intranet, or save it in your local hard drive? DVMixer¢â enables live video sources, like a Hi-8 video camera and/or Digital camcorder, captures the content and delivers it over the Internet or intranet. This content also can be saved for on-demand playback at a later time
Streaming On-Demand Content
Want to deliver a streaming video album, training video, video diary, CD movie, and other saved files over the Internet or an intranet? A VHS tape, Video-CD title, files in your hard drive and/or files over the network, can be easily trans-coded to WMV (ASF), RM, Quick time and MPEG4, allowing you to stream stored content from DVMixer¢â to an individual PC on request.

DVMixer Usage Scenarios
This section describes usages of DVMixer.
GAPsoft Stream software product provides a high-level architectural overview of how customers can stream both live and on-demand content over the Internet and intranet environments using GAPsoft encoding/trans-coding technologies. The Application Model introduces the notion of multi source-specific Utilities. The encode/decode Framework component is a collection of cooperating objects that provide an integrated solution within an application or technology and which is intended for customization by the developer or user.
Multimedia means better communication. Video and audio surpass the communicative power of static text and graphics, which is one reason video and audio enabled applications are the next wave of Network-based technology. GAPsoft provides a complete platform for integrating video and audio into a number of Web-based and system-based applications. The following scenarios illustrate only a few of the many ways you can use GAPsoft Stream based technologies.
 
Streaming Video Album & Video Diary
 
  • Make your personal, family and friends memorable content and/or diary as of birthday, wedding, vacation, travel, graduation and other specific days using multimedia library in hard drive of computer machines from digital camcorder
  • Deliver and enjoy the multimedia streaming movies over the Internet with your family and friends. Enable it to read industry-standard bit-streams such as DV, Windows Media Video (ASF), Real Media, Quick time, AVI, and MPEG1 & 2 files making it easy to repurpose to Internet streaming formats as ASF, RM, Quick time & MPEG4 files. And attach the movies to an email or attach in your hard drive for playback at a later time.
Distance learning
 
  • Extend the classroom by streaming taped instructions over the Internet or intranets. By expanding the audience, institutions can maximize the value of their initial training investment
  • Make it easier for trainers to generate compelling and memorable content, and make it easier for students to receive training whenever and wherever they need it, using their own PCs
  • Deliver multimedia presentations over corporate networks and the Internet, and save substantially on training materials, binders and CD-ROMs
  • Provide a single training source that can be immediately updated and accessed on the network without having to print and distribute revised material across the company
Corporate Communications
 
  • Provide live broadcasts of important organizational briefings, such as internal presentations or presentations for the press or analysts, to everyone within the organization
  • Capture live presentations for playback, and build a library of multimedia information for reference and training on-demand
  • Reduce travel costs by eliminating the need for employees to attend training or meetings in distant locations by streaming the event to their PCs
Other applications
 
  • Source stream re-delivery: DVMIXER enables streaming out of the encoded video source and video/audio splitting as well as captions and logo insertions for final re-delivery. Stored video on hard drive, tape, digital camcorder and video sources over the network, every video source is available to stream out on its high quality.
  • Real time captions, subtitles, spot news, logos, and ad insertion are available. Streamed video can also be dubbed and video inserts which matches with the music can be done as various editing or re-editing options.
  • Scheduled programs or commercial stream out is also available live and on-demand. Stored commercial files and live captured inputs can be decoded as well as VTR tape sources can be captured real time to stream out.
  • Traditional broadcasting system has complicated procedures to stream out, e.g. sports broadcast in a stadium, as broadcasts as such would involve wired camera inputs and audio/video hardware analog switching system which would then be inputted to the SNG system. This signal would be picked up by the satellite to be sent to the broadcasting station to proceed with editing, captions and effect insertion to encode and broadcast real time over the Internet.
  • DVMixer has advantages of shortening ready time to broadcast with wireless modem and/or wireless LAN card built-in notebook system cabled to the camera. Wireless input stream will be decoded, captioned, switched, encoded and streamed out over the Internet real time.
