Software tools for analysis of digital
media files on a PC
Rohde & Schwarz has introduced the R&S Vega Suite,
a set of software tools for in-depth, offline analysis of
media files on a PC. Broadcast operators and service providers
can use this software to find signal faults and optimize
content. Manufacturers of DTV components use the R&S
Vega Suite to check that their products are standard compliant,
for quality assurance testing and to improve the performance
of their products. The software is ideal for analyzing compressed
audio and video signals and MPEG-2 transport streams.
Broadcast operators and service providers have to ensure
network availability. They can use the R&S DVM and R&S
DVMS monitoring systems and the R&S ETL TV analyzer
to immediately detect faults in live signals and record
the faulty signal segments. The R&S Vega Suite now makes
it possible to analyze these segments, and their video and
audio characteristics, in detail on a PC. Signal faults
are quickly found and eliminated, allowing operators to
optimize the quality of their content. Extensive visualization
options simplify analysis, and the save function makes it
easy to document results.
The R&S Vega Suite supports the latest standards and
technologies, making it especially useful for developers
of DTV components and devices such as encoders, multiplexers
and transcoders. The software is ideal for analyzing MPEG-2
transport streams (DVB, ATSC, ISDB) and MXF files. The H.264,
H.264 SVC, H.264 MVC, H.263, MPEG-1, MPEG-2, MPEG-4, AVS,
VC-1 video formats can be analyzed. The MPEG-1/MPEG-2 Audio,
Dolby Digital, Dolby Digital Plus, Dolby E, AAC, HE-AAC
and MP3 audio standards are supported. Data streams such
as teletext, DVB subtitling, closed captioning, XDS and
EPG can also be analyzed. Manufacturers can use the software
to check their products for compliance with relevant standards
and for interoperability, coding efficiency and audio-video
synchronization. To save time, batch processing can be used
to automatically analyze multiple files.
The R&S Vega Suite software was developed by Interra
Systems. The Interra software is the ideal enhancement for
real-time analysis instruments from Rohde & Schwarz.
Since 2007, the two companies have cooperated to provide
analysis software for H.264 video.
