Product Overview

The Video Quality Analyzer VISUALmpegES, as a part of the complete MPEG stream analyzer product range VISUALmpeg, offers several measures for in depth MPEG video analysis. By making additions to the decoded pictures with information which ensures the MPEG system parameter become visible, MPEG is no longer a theoretical issue, but a visible compression standard. The user gets detailed and visual information about the whole stream, from the header layer down to the macroblock and block layer. VISUALmpeg is completely software based, needing no special hardware and running on Windows from either desktops or laptops. The possibility to analyze different parts of a MPEG stream (motion estimation, quantization, bit allocation..) and to compare different streams, makes VISUALmpeg becoming a very useful tool for those who need to make MPEG investigation during product development. Main feature of VISUALmpegES is the visualization of all MPEG related parameters. VISUALmpegES holds an intuitive GUI with a clear and configurable visualization of the assessment results.

Analysis Features

- Header Information: display of all MPEG related Header Tables and contents
- Picture Coding Type: analysis of Picture coding types (I,B,P)
- Bit allocation: visualization of the bit distribution within a MPEG coded frame
- Quantization: visualization of Macroblock quantizer values within a MPEG coded frame
- DCT Coefficients: Analysis of all DCT Coefficients inside Macroblock
- Motion Vectors: display of coded motion vectors inside a MPEG frame
- Macroblock Coding Types: analysis and vizualization of differnet macroblock coding types
- Picture Frequencies: analysis of different picture frequencies coded with a frame
- Motion Compensated Frame: display of motion compensated frames inside B- and P-Pictures
- Differential Frame: display of differential (residual) frame inside B. and P-Pictures
- Slice Structure: display of slice structure within a MPEG frame
- I,B,P Statistics: Statistical analysis of I,B and P Frames
- Error Loger: MPEG conformance testing and checking

 

VISUALmpegES can be used for:

- optimizing MPEG / H.264 Codecs
- saving time and costs during Encoder development (e.g. debugging different modules)
- analyzing different Modules of an encoder (e.g. Motion Estimation, Bit Allocation, ...)
- Finding the correct MPEG / H.264 Encoder Settings (e.g. GOP Size, Motion Search Range., Bitrate, Quantization...)
- comparing different Encoder
- comparing different MPEG / H.264 Files
- teaching how MPEG / H.264 compression works
