The transmission speed enhancement techniques in TKR
Šťovíček, Petr ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The purpose of this work is to assess and propose possible methods for increasing the transmission speed of the cable television distribution, concretely the UPC network in Brno. The first part of work collectively processes general knowledge and gives the reader into the issue. After that follows an analysis of TV cable networks UPC in Brno, especially view of data transmission. After familiarization with the physical aspect of the network is described data communications itself, including standard DOCSIS, respectively EuroDOCSIS. Particular attention is paid to factors that have effect on data transmission and speed. Benefit is the calculation of dividing ratio in different parts of the network and compared with the real load. As far as possible in the given work results of measurements with regard to the quality of the network. The last part is about how to increase speeds. Perspective solution is mainly a technology which is based on standard EuroDOCSIS 3.0, which introduces the concatenation of individual channels. Result of made tests of first cable modem EuroDOCSIS 3.0 confirms the very high speeds and currently preparedness for other major step in so long development of TV cable network.

Barcodes Reading Library
Novohradský, Petr ; Přibyl, Bronislav (referee) ; Kubíček, Radek (advisor)
This work deals with the decoding of different types of barcodes in the image. Selected types of bar codes are described in detail. Presents an approach to decode linear and matrix bar codes. The practical part deals with the design and implementation of software library for reading selected types of bar codes in Java.

Implementation of protocol IPv6 in ISP
Vilímek, Josef ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
Cílem práce je popsat obecné fungování IPv6 protokolu a nastínit tak jeho možnou implementaci u poskytovatele internetu (ISP). Implementace je popisována na příkladu společnosti UPC Česká republika, a.s. Práce shrnuje technické údaje o IPv6 a možné postupy v implementaci pro kabelové operátory. Výsledkem je konkrétní postup, který je vytvořen na základě analýzy fungování stávající sítě UPC. Součástí postupu implementace jsou i konkrétní doporučení DHCP a DNS serverů.
