Characteristics
Applications
The ES
Analyzer provides the ability to view the moving picture from within
a PES stream and carry out a whole range of sophisticated new tests
on the lower layers of an elementary stream within a Transport Stream.
In addition, it both displays and analyses a range of extended media
formats, including ATSC Closed Captions, DVB Subtitles, and Teletext.
Feature Details
CODEC Views and Analysis
The sequence header can be viewed along with the extensions.
The picture rate, chroma format and the video type (NTSC, PAL, etc.)
appear in the status bar when the sequence headers are displayed.
The stream can be run through with the option of analysis of the stream
at picture level or at the macroblock level. When analyzing the group
of pictures (GOP), it is possible to randomly access any picture from
within the group, view the picture type, spectrum, and display picture
size plots. The user can zoom in on the picture to see details at
the slice or macroblock levels or view the encoded picture. Picture
player can be operated until degradation in quality is seen, the picture
paused, and the details reviewed down to the macroblock level. An
easy mechanism is provided to switch between the picture display and
the data analysis windows.
Macroblocks can be selected, and
detailed coding investigated. The picture analysis can be performed
with special displays of quantizer scale distribution, slice size
distribution, macroblock-size spectrum, and motion vector plots.
Quantizer matrices can be downloaded for any picture, at most
four matrices, namely intra-quantizer, non-intra-quantizer, chroma
intra-quantizer, and chroma non-intra-quantizer matrix.
The
picture coding extension is always displayed, while the other picture
extensions are displayed on tabbed folders; these are copyright extension,
picture display extension (PDE), picture spatial scalable extension
(PSSE), and picture temporal scalable extension (PTSE). The B and
P frame motion vector displays allow you to select Macroblock Intra,
pattern motion backward and forward together with macroblock quantization,
quantizer scale DCT type, and motion vector format.
Comprehensive
error logging is provided during stream analysis, and selectable error
filters are available. There is also an automated "regression" test
mode that can save data from selected fields to report files for viewing
later.
The audio analysis capability includes navigation to
any audio frame and viewing its details, header, and frame data plots.
Audio descriptors are interpreted and displayed in higher level streams
and validated against the stream.
Extended Media Views
and Analysis
Two primary forms of ATSC Closed Caption
analysis are offered, CC-EIA608 and CC-EIA708. CC-EIA746 support is
also supported in the EIA608 mode. In addition to displaying the captions
for each frame superimposed on the video are Caption Statistics. These
include Packet and Block information, Active Window plus Window Definition
and Style parameters. These statistics may also be saved to a file.
DVB Subtitle data for the current display is provided, including
Page and Region composition, Color Lookup Tables (CLUT), and Object
data. An Object view displays a decoded bitmap of a selected object.
A Page view renders the regions listed in the Page Composition on
a blank screen.
Teletext data incorporated into DVB streams
may also be displayed and analyzed. The Color Map Table, Decoded Display,
and Decoding Parameters are displayed, which provide details of the
teletext encoding data. Enhanced teletext support (VBI) is available
in conformance with ETSI EN 301-775.
