Implementation of the I2S Driver into the Freescale MQX RTOS
Možný, Karel ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
This thesis deals with design and development of a I2S module driver for real-time operating system MQX running on a ColdFire V4 architecture based processor. Further there are presented circuit diagrams and PCBs created for testing of functions and properties of the driver. Signal input is a digital audio in form of S/PDIF interface, output is an analogue signal, that can be listened by the means of a headphone amplifier. The conclusion describes a sample application demonstrating function of the driver on developed hardware.

Library for Efficient Video Capture in 3D Application
Pospíšil, Petr ; Navrátil, Jan (referee) ; Havel, Jiří (advisor)
This thesis deals with library for recording video in the background of 3D application. A library is designed to work under the Microsoft Windows and Linux operation systems. It records image and also sound. Image recording is supported in OpenGL, Direct3D9, Direct3D10 and Direct3D11. To reduce video data size, library supports image compression using MJPG codec. Audio is recorded by WaveForm audio, Windows Core Audio or ALSA. Recorded sound is for whole operation system. A library is able to record up to two audio streams to accommodate possible microphone input. It can mix audio data together if needed. Output data are then written into AVI file. It is possible to write own text information as overlay that is rendered as part of application screen output.

Audio distribution on the Internet
Gleza, Jan ; Jandoš, Jaroslav (advisor) ; Šedivá, Zuzana (referee)
This thesis analyzes current situation of audio distribution on the Internet, its authorized and unauthorized option. Predicts future development by application of cryptography and offers solutions for increase the share of authorized audio distribution by means of three pillars -- shopping simplification, increase user friendliness and offer to include added value to authorized distribution.
