Moderní elektronika se stává nezbytnou součástí dnešních automobilů. Dynamicky se rozvíjející informační a telematické služby nacházejí široké uplatnění v automobilovém prostředí. Moderní aplikace vyžadují přenos velkého množství dat, což jim zajišťují dnešní komunikační protokoly. Cílem mé diplomové práce je analýza a návrh implementace multimediálních sítí do automobilů. Jednotlivé návrhy jsou charakterizovány a srovnány podle požadavků, kterým jsou v automobilovém prostředí vystaveny. Navržené topologie využívají nejen dnes používané technologie, ale jsou zde i návrhy, které nebyly dosud v automobilovém prostředí použity. Jednotlivé návrhy jsou srovnány a vyhodnoceny z pohledu automobilového výrobce.Automotive manufacturers face interesting challenges as electronic devices are becoming essential in modern vehicles. One of the most rapidly growing domains is infotainment and telematics, where applications require a large amount of data to be transmitted on-board and also exchanged with the external world. This thesis is intended to analyze possible implementations of multimedia networks in vehicles, in relation to various aspects and features in this area. Based on various requirements different multimedia networks are proposed and studied, making a comparison between them with regards to a number of criteria. A broad approach during the investigation of the multimedia protocols is chosen in order to enlarge the area of used technology. The comparison gives an insight into the particular proposed solutions from the automotive industry’s point of view. Based on the comparison of the proposals a suitable multimedia network can be chosen.

GPS/INS Sensor Fusion Using GPS Wind up Model

A method of stabilizing an inertial navigation system (INS), includes the steps of: receiving data from an inertial navigation system; and receiving a finite number of carrier phase observables using at least one GPS receiver from a plurality of GPS satellites; calculating a phase wind up correction; correcting at least one of the finite number of carrier phase observables using the phase wind up correction; and calculating a corrected IMU attitude or velocity or position using the corrected at least one of the finite number of carrier phase observables; and performing a step selected from the steps consisting of recording, reporting, or providing the corrected IMU attitude or velocity or position to another process that uses the corrected IMU attitude or velocity or position. A GPS stabilized inertial navigation system apparatus is also described

Video Conferencing - User Interface with a Remote Control for TV-sets

By using Axis pan/tilt/zoom cameras it is possible to create a simple, high quality video conference system, without the need for a separate computer to control the system. This can be achieved by connecting the camera to a standard television set and utilize open standards like the HDMI feature Con- sumer Electronics Control (CEC). With CEC it should be possible to control the system using a standard TV remote control, thus moving a major part of the user interaction to an external device. Though this approach has its ben- efits by removing the need for Axis to provide a separate remote control, it also sets higher requirements on the user interface. Especially with regards to the usability since TV remote controls differ in many ways depending on the manufacturer. A user interface with a TV remote control solution has been prototyped and implemented demonstrating a peer-to-peer video conference system. This was done through the use of on-screen displays, an iterative design process with multiple usability tests and an evaluation of similar video conference products as a basis. The test results shows that a prototype with high usability was cre- ated which the users felt confident using

Television Production : Managing the Technology

The idea to write the thesis about television production came into my mind a long time ago. I knew that this area of media technology was the most interesting for me. I had an internship in Aito Media Oy television production company in 2009, and I studied TV Production at Ferris State University, USA for one academic year 2010-2011. The main objective for my thesis is to research, compare and describe all steps in production of a television show from the developing an idea through planning, budgeting, shooting and editing to the final release of the TV show on the screen. Also I would like to observe the technologies used nowadays and determine the role of a producer in the TV production. To reach my objective, I read several books and electronical materials on different topics about phases of the production, equipment and techniques, communication and documentation. Furthermore, I use knowledge from my own experience, which I got while studying and making practical tasks at Television and Digital Media Production program at Ferris State University. I learned the professional skills required in all aspects of different phases of television production, including studio workflow, camera operation, field equipment, multicamera directing and the responsibilities and organ-izational expertise of the producer. At the same time, I explored the latest production techniques and technology, such as audio and lighting work-stations, non-linear editing, high-definition television and 3D television.Ajatus tehdä opinnäytetyöni televisiotuotannosta tuli jo kauan sitten, koska tiesin, että se on henkilökohtaisesti mielenkiintoisin alue mediatekniikassa. Olin työharjoittelussa Aito Media Oy tv-tuotantoyhtiössä vuonna 2009, ja lukuvuodessa 2010-2011 opiskelin Ferris State University:n TV-tuotanto ja Digimedian koulutusohjelmassa, Yhdysvaltoissa. Työn päätavoitteena on tutkia, vertailla ja kuvata kaikki tv-ohjelman tuotannon vaiheet alkaen idean kehittämisestä, sekä suunnittelun, budjetoinnin, kuvausten ja editoinnin kautta lopullisen tv-ohjelman version julkaistamiseen. Myöskin haluan havainnoida nykyaikaisia tekniikoita ja määrittää tuottajan roolin tv-tuotannossa. Tavoiteeni saavuttakseni olen lukenut useita kirjoja ja elektronisia lähteitä erilaisilla aiheilla, kuten tv tuotannon vaiheet, laitteisto ja tekniikat, viestintä ja dokumentointi. Lisäksi käytän tietoja omasta kokemuksestani, mitkä sain kun opiskelin Ferris State University:ssa ja tein erilaisia tv tuotannon liittyviä tehtäviä. Olen oppinut tarvittavaa ammattitaitoa kaikilla tv-tuotannon vaiheilla, kuten työnkulku studiossa, cameran operointi, tuotantolaitteiden käyttö kentällä, monicameroiden ohjaus sekä tuottajan vastuut ja järjestelytaidot. Samalla tutkin viimeisimpiä tuotantomenetelmiä ja tekniikkaa, kuten ääni- ja valaistustyöasemien käyttöä, käytössä olevia editointiohjelmistoja ja teräväpiirtotelevision ja 3D television ominaisuuksia

Exploiting Wireless Sensors: a gateway for 868MHz sensors

[ANGLÈS] The great interest in monitoring everything around us has increased the number of sensors that we utilize in our daily lives. Furthermore, the evolution of wireless technologies has facilitated their ubiquity. Moreover, is in locations such as homes and offices where exploitation of the data from these sensors has been more important. For example, we want to know if the temperature in our home is adequate, otherwise we want to turn on the heating (or cooling) system automatically and we want to be able to monitor the environment of the home or office remotely. The knowledge from these sensors and the ability to actuate devices, summon human assistance, and adjust contracts for electrical power, heating, cooling, etc. can facilitate a myriad of ways to improve the quality of our life and potentially even reduce resource consumption. This master?s thesis project created a gateway that sniffs wireless sensor traffic in order to collect data from existing sensors and to provide this data as input to various services. These sensors work in the 868 MHz band. Although these wireless sensors are frequently installed in homes and offices, they are generally not connected to any network. We designed a gateway capable of identifying these wireless sensors and decoding the received messages, despite the fact that these messages may use a vendor?s proprietary protocol. This gateway consists of a microcontroller, a radio transceiver (868-915 MHz), and an Ethernet controller. This gateway enables us to take advantage of all the data that can be captured. Thinking about these possibilities, imultaneously acquiring data from these various sensors could open a wide range of alternatives in different fields, such as home automation, industrial controlling? Not only can the received data be interesting by itself; but when different sensors are located in the same environment we can exploit this data using sensor fusion. For example, time differences in arrival and differences in signal strength as measured t multiple receivers could be used to locate objects. The final aim of this thesis project is to support diverse applications that could be developed using the new gateway. This gateway creates a bridge between the information that is already around us and our ability to realize many new potential services. A wide range of opportunities could be realized by exploiting the wireless sensors we already have close to us.[CASTELLÀ] El gran interés en el seguimiento de todo lo que nos rodea ha incrementado el número de sensores que utilizamos en nuestra vida diaria. Por otra parte, la evolución de la tecnología inalámbrica ha facilitado su instalación. Es en lugares como casas y oficinas donde el aprovechamiento de los datos de estos sensores ha sido más importante. Por ejemplo, si queremos saber si la temperatura en casa es la adecuada para activar el sistema de calefacción (o refrigeración) de forma automática. La capacidad para accionar dispositivos externos y ajustar los contratos de energía eléctrica, calefacción, refrigeración, etc. puede facilitar una gran variedad de formas de mejorar la calidad de nuestra vida y, potencialmente, incluso reducir el consumo de recursos. Este proyecto de tesis ha creado una gateway que detecta el tráfico de sensores inalámbricos con el fin de recoger datos de los sensores existentes y proporcionarlos como entrada a varios servicios. Estos sensores funcionan en la banda de 868 MHz. A pesar de que estos sensores inalámbricos son frecuentemente instalados en hogares y oficinas, generalmente no están conectados a ninguna red. Hemos diseñado una gateway capaz de identificar estos sensores inalámbricos y descodificar los mensajes recibidos, aunque estos mensajes pueden utilizar un protocolo exclusivo del propietario. Esta gateway consta de un microcontrolador, un transceptor de radio (868-915 MHz) y un controlador Ethernet. Esta gateway nos permite tomar ventaja de todos los datos que se pueden capturar. Pensando en todas estas posibilidades a la vez, la adquisición de los datos de estos diversos sensores podría abrir una amplia gama de alternativas en diferentes campos, como la automatización del hogar, control industrial ... No sólo los datos recibidos pueden ser interesantes, sino que los diferentes sensores que se encuentran en el mismo entorno pueden explotar estos datos mediante la fusión de sensores. Por ejemplo, las diferencias de tiempo en la llegada y las diferencias en intensidad de la señal, según lo que determina múltiples receptores también podría ser utilizado para localizar objetos. El objetivo final de este proyecto de tesis es dar apoyo a las diversas aplicaciones que pueden ser desarrolladas utilizando la nueva gateway. Esta gateway crea un puente entre la información que ya está a nuestro alrededor y nuestra capacidad de realizar muchos nuevos servicios potenciales. Una amplia gama de posibilidades puede ser generada mediante la explotación red de sensores inalámbricos que ya están presentes en nuestro alrededor.[CATALÀ] El gran interès en el seguiment de tot el que ens envolta ha incrementat el nombre de sensors que utilitzem en la nostra vida diària. D'altra banda, l'evolució de la tecnologia sense fils ha facilitat la seva instal·lació. És en llocs com cases i oficines on l'aprofitament de les dades d'aquests sensors ha estat més important. Per exemple, si volem saber si la temperatura a casa és l'adequada per activar el sistema de calefacció (o refrigeració) de forma automàtica. La capacitat per accionar dispositius externs i ajustar els contractes d'energia elèctrica, calefacció, refrigeració, etc. pot facilitar una gran varietat de formes de millorar la qualitat de la nostra vida i, potencialment, fins i tot reduir el consum de recursos. Aquest projecte de tesi ha creat una gateway que ensuma el tràfic de sensors sense fils amb la finalitat de recollir dades dels sensors existents i proporcionar-les com a entrada de diversos serveis. Aquests sensors funcionen a la banda de 868 MHz. Malgrat aquests sensors sense fils són sovint instal·lats en llars i oficines, generalment no estan connectats a cap xarxa. Hem dissenyat una gateway capaç d'identificar aquests sensors sense fil i descodificar el missatges rebuts, tot i que aquests missatges poden utilitzar un protocol exclusiu del propietari. Aquesta gateway consta d'un microcontrolador, un transceptor de ràdio (868-915 MHz) i un controlador Ethernet. Aquesta gateway ens permet prendre avantatge de totes les dades que es poden capturar. Pensant en totes aquestes possibilitats a la vegada, l'adquisició de les dades d'aquests diversos sensors podria obrir una àmplia gamma d'alternatives en diferents camps, com ara l'automatització de la llar, control industrial ... No només les dades rebudes poden ser interessants, sinó que els diferents sensors que es troben en el mateix entorn poden explotar aquestes dades mitjançant la fusió de sensors. Per exemple, les diferències de temps en l'arribada i les diferències en intensitat del senyal segons el que determina múltiples receptors també podria ser utilitzat per localitzar objectes. L'objectiu final d'aquest projecte de tesi és donar suport a les diverses aplicacions que poden ser desenvolupades utilitzant la nova gateway. Aquesta gateway crea un pont entre la informació que ja està al nostre voltant i la nostra capacitat de realitzar nous serveis potencials . Una àmplia gamma de possibilitats pot ser generada mitjançant l'explotació de la xarxa de sensors sense fils que ja tenim a prop nostre
