Realization and implemention of RDS message management software
 Heralt, Jiří ; Zezula, Radek (referee) ; Koutný, Martin (advisor)
The purpose of this work was realization and implementation of two applications for the management of Radio Data System (RDS) messages. These applications will be subsequently used in the Czech Radio Ostrava to support two RDS services, namely the Traffic - Announcement Identification and Radiotext. Both applications are secured against unauthorized use by incompetent users through a password - protected access, access rights and encryption of passwords in initialization files. The text of this work is divided into three parts. The first describes the system RDS and services provided by it and implementation of RDS in the Czech Radio Ostrava. The second part deals with the realization of both applications and the last part describes the implementation itself. The work shows all applications windows. Work also includes all the flow charts. The list of all broken down by subroutines is given in the appendix.

Objektivní porovnání účinnosti jednokanálových metod potlačení šumu
 Koula, Ivan ; Heralt, J.
The contribution tries to evaluate objectively the efficiency of most widely used one-channel noise cancellation methods for a speech record. In this contribution three basic one-channel methods are compared (spectral thresholding, spectral subtraction and RASTA algorithm). The efficiency of designated methods is evaluated by percentage hit rate of isolated words recognition. This test enables an objective evaluation of methods with regard to the intelligibility.
