Follow on Google News | USB-Powered MPEG2 Encoder with PC Text/Graphics Overlay, 4-Channel Picture-in-Picture Encoding & SDKIncorporating hardware A/V multiplexing, graphics overlay and MPEG2/1 compression, USBOSDM2 allows multiple picture-in-picture video mixed with unlimited overlays to simultaneously appear on PC/TV screen, record to MPEG file, and stream over network
By: Inventa Australia Pty Ltd 1. With multi-channel video inputs, USBOSDM2 allows 4 video channels to simultaneously appear on the output video frame, each to be independently adjusted with: -- Arbitrary size and location on the output video frame: thus forming various picture-in-picture, picture-by-picture scenarios; -- Signal source from 6 possible sockets; -- Both PAL and NTSC input are supported; -- Colour brightness, contrast, hue, saturation and sharpness; -- Horizontal and vertical mirroring; -- 2-Times Zooming from any point inside the video frame; -- Channel boundaries. For audio input, USBOSDM2 can select 4 stereo channels each with gain and mute controls from 4 line-in and 2 mic sockets, to be simultaneously mixed into one MPEG audio stream. 2. Overlaying (Superimposing) -- Text overlay can use any font under Windows, inc. different alphabet, colour, typeface, style and any size, plus alpha transparency and blinking options. Text background can be either transparent or opaque. Text can also Auto Scroll across video frame: -- Text File overlay allows text from files to be displayed on video frame using the various options as Text Overlay. Multiple lines of text from a file can also be Auto-Scrolled from right-to-left across the video frame: -- Timer overlay continuously updates current time per second with optional date display. Counter Timer can also be defined to Count Down or Count Up similar as a Stopwatch. -- Rectangle overlay draws lines with any width, height and colour, therefore can be used easily to cover any area on the video frame. -- Box overlay with partially transparent background can be used to highlight the text. -- Graphics File overlay loads bitmap files onto the video with Transparent or Opaque background mode: using the Transparent mode, complex graphs with uniform background can be clearly overlaid on live video showing all details without any trace of the background colour, similar as the "Blue Screen" effects used in video editing process. -- Geometric Shape overlay allows users to draw lines, arcs, circles, rectangles, polygons, arrows etc. with different colour, length, thickness on the live video at any location. Item-specific parameters such as line length, arrow shaft, arrow angle, arc angle, circle radius etc. can all be user-defined and modified easily. Overlay items defined can be reloaded each time the USBOSDM2 program starts. Convenient overlay operations inc. instant moving, clear screen, font downloading, overlay disable/enable, alpha value, blinking, background mode, etc are provided through Overlay Setup Dialog Window. 3. Live Video Preview on PC is provided by a floating Video Window that can be arbitrarily resized and moved around on PC screen, made into full-screen mode or minimized as an icon on the task-bar: live video from all input channels or from one channel can be selected to fill the preview window or full screen. The Video Window also has a Drop-down Menu offering many useful functions inc. start/stop/pause/ 4. Two TV Out Ports output the channel-mixed and text/graphics- 5. MPEG File Recording has many useful options: -- All MPEG Compression Parameters are user-definable through tabbed dialog boxes. MPEG compression bit-rates from 1Mbps to 25Mbps, DVD, SVCD, VCD, MPEG2 and MPEG1 encoding types, Constant and Variable bit-rates, GOP structure, etc parameters are supported. Encoded DVD/VCD/SVCD files can be burned as DVD/VCD/SVCD movie disks immediately without any software conversion. -- Recording file name can have many user-defined fields such as date/time, MPEG-compression bit-rate, frame-size, video signal type, device number, etc. -- Recording timer and calendar scheduler are provided. Timer can be adjusted after recording started. Scheduler allows flexible file name prefix and daily/weekly etc. repeat recording modes. -- Recording MPEG file can be real-time arbitrarily Split manually or according to pre-defined file size or recording time -- useful for creating multiple fixed-sized files for easy DVD/CD burning. -- Recording can be paused and resumed without closing the current file. -- Recording status can be displayed on the video window in used-selectable text size, colour, location, etc. 6. USBOSDM2 records high quality MPEG video up to 25Mbps with always lip-synched audio: at the default 8Mbps DVD-format recording setup, the recorded video can play back in visually indistinguishable result as the original input. Even at lower bit rate and frame size setups such as SVCD and VCD settings, the resulting video also have very good quality and keep A/V sync all the time: sample recording clips can be downloaded here. 7. USBOSDM2 can function as a MPEG video streaming server: Video Streaming can be started at any time independent of video recording status, both multi-cast and uni-cast UDP streaming are supported. Streamed video can be received by client software such as VideoLan etc. in real-time over any IP network. 8. PAL and NTSC video input are both supported, incoming video signal's TV type is automatically detected and displayed, PAL or NTSC MPEG encoding video standard can be user-selected, mixed PAL and NTSC signals among input channels are allowed: PAL video can be displayed and encoded as NTSC format and vice-versa. 9. Still Image can be grabbed at any time: the grabbed video frame can be saved as graphics files in the format of BMP, JPEG, GIF, TIFF or PNG. 10. Multiple USBOSDM2 Devices can run simultaneously on one PC: all devices can operate independently with live video preview inside the same Video Window. All devices can start/stop recording or streaming simultaneously or separately with their own MPEG encoding parameters. 11. Various Command-Line Parameters facilitate the USBOSDM2 software to be launched and exit in batch mode with automatic recording, streaming operation enabled at start-up. 12. Many Device Setup Options including hardware IC reset, DirectX parameters, colour bar generation etc. are provided. 13. Comprehensive Software Development Kit (SDK) is optionally available for writing customized software to implement all the above functions plus many more using simple function calls from programming language such as VB, C++, etc, without directly interfacing the complicated hardware. 14. USBOSDM2 runs under Microsoft Windows 7, Vista or XP on laptop or desktop PCs.
