Analysis and Detection of Multimedia Types in RTP Traffic
Kmeť, Martin ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This thesis deals with the issues of detecting the codec used for the encoding of voice data carried by the RTP protocol without having access to the information carried by signalisation protocols in VoIP applications. Its main goal is to create and implement a fast algorithm for detecting the codec used for voice transfer via the RTP protocol. This algorithm should be fast enough to be used for offline analysis of captured data as well as for real-time online analysis. For research of possibilities were compared two approaches of detection. Detection by the characteristics of the codecs was chosen to solve the problem itself. Within the solution was performed data analysis and implementation of the application followed by testing on data.

Smart Home Control
Fučík, Jan ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis summarizes the subject of intelligent homes and describes commonly used standards and commercial solutions on the market. The thesis covers the design of a low-cost and easy to use smart home system which can be managed over the internet, uses a genetic algorithm for heating regulation optimization and its central computing unit is a low-cost, embedded device with low power consumption. The functionality of the system is verified on a practical application of heating regulation in a house. The efficacy of the system for energy savings is shown; it is based on measured data statistics.

Web Based Audio/Video Lecture Browser: Porting of the Browser to MySQL Database
Janovič, Jakub ; Fapšo, Michal (referee) ; Szőke, Igor (advisor)
This project deals with a web-based lecture browser, whose goal is to simplify the gaining of knowledge with the use of multimedia. It presents an existing lecture browser that was created for a diploma thesis at FIT VUT Brno. Demonstrated are the technologies that are used and which will be used to migrate the browser to a MySQL database and to develop a transcription module for speeches. The reader will be acquainted with an analysis and model of the new application. Furthermore, implementation methods for development and subsequent testing are discussed. At the end of the project is a conclusion about the future development of web-based lecture browsers.

Prednasky.com - a framework for automatic data processing
Kalfus, Jan ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
This bachelor's thesis presents the design and implementation of a framework for automated multimedia data processing in Python. The created framework enables the user to decompose the editing process into atomic tasks, which can be run in a computer cluster, and handles their interconnection including automatic dependency resolution. The framework's functionality has been successfully tested using tasks to process recordings of lectures. Also, a web interface has been created, which enables the administrator to manage the system and lecturers to submit lecture recordings for processing.

A Tool for Tracking RTP Streams
Kmeť, Martin ; Matoušek, Petr (referee) ; Skokanová, Jana (advisor)
This document describes the development of the algorithm and test application for detection of RTP streams in computer networks. One of the results will be a tool in Python language recognising RTP streams in data filtered from network interface in real time or from the data in pcap format.

The API of a Video and Image Datastore
Fröml, Vojtěch ; Volf, Tomáš (referee) ; Zendulka, Jaroslav (advisor)
This master's thesis proposes and implements an extension of the database interface VTApi which is being developed as a part of the MV ČR project "Tools and methods for video and image processing for terrorism prevention" at FIT VUT. This interface provides support for representation, management and indexation of multimedia data and related descriptive metadata used by analytic applications based on computer vision. It currently uses DBMS PostgreSQL as its default datastore. Paper describes basic techniques for processing image and video data, VTApi concept and proposes and implements its modifications for the purpose of supporting multiple types of datastores. As an example of an alternative datastore, support for usage of a SQLite database is integrated into VTApi.

Multimedia Player for iOS
Singh, Kevin ; Číka, Petr (referee) ; Grabovský, Štěpán (advisor)
Diploma work „Multimedia player for iOS“ deals with the description of the video formats such as HLS, MP4, MPEG Transport Stream, and Dash. Next, it continues with protected content DRM, VAST advertisements and analytics tool called Google Analytics. During compilation of this diploma work was created a framework in programming language Swift. This framework is basically a player, that besides playing Interactive videos is able to show ads, subtitles, can change the video quality, AirPlay and download the content for offline playing. A feature to play a protected content could not be done as a developer's request for a product deployment SDK Fairplay was refused from an SDK owner. A testing app was also created that implements developed a framework and prove the functionality of the developed functions.
