Customer: Beuth University of Applied Sciences, Berlin
Beuth University of Applied Sciences Berlin is one of Germany‘s largest state universities of applied sciences. With a wide range of forward-looking degree courses and a staff of highly qualified specialists, Beuth University encourages the career opportunities of all prospective and current students, regardless of their social background.
Teach students the fundamentals of coding concepts and help them to understand the functionality of modern encoding standards.
Illustration of the coding concepts using the real video data and visualization the structure of the encoded bit streams by means of professional toolset Elecard StreamEye Studio involved in the learning process.
Learning process that enables students to experience the eﬀects of playing around with the encoder parameters and analyze these eﬀects using well established engineering measures.
The above mentioned tasks are greatly simplified be Elecard StreamEye and the tools included in the Studio version.
The following ﬁgure taken from the StreamEye decoded picture view shows how students can visualize both forward and backward prediction motion vectors, diﬀerent types of macro blocks depending on content, and diﬀerent transform block sizes in an H.264 coded video stream. Colors and shapes are used to provide an initial overview on these aspects. More details can be taken from the block information available in a separate window.
To compare diﬀerent encoder settings, the bar chart for the video stream shows the students information about the bit allocation to the diﬀerent types of frames and allows an initial estimation of the video quality using the estimated PSNR as a measure. More detailed quality measurements can be carried out using the Elecard Video Quality Estimator, which is part of the Studio.
"Thanks to Elecard developers for a great tool making it easier to understand the art of video compression. The above-mentioned tasks are greatly simpliﬁed by Elecard StreamEye and the tools included in the Studio version."
