This paper confirms the existence of short-term and long-term variation of the required bandwidth for MPEG videostreams. We show how the use of a small amount of buffering and GOP grouping can significantly reduce the effect of the short-term variation. By introducing a number of bandwidth renegotiation techniques, which can be applied to MPEG video streams in general, we are able to reduce the effect of long-term variation. These techniques include those that need the a priori knowledge of frame sizes as well as one that can renegotiate dynamically. A costing algorithm has also been introduced in order to compare various proposals against each other.

<p>Active safety systems for automobiles in the form of camera systems have evolved rapidly the last ten years, Autoliv Electronics in Linköping develops multiple such systems. In their development process there is a need for a Break out Box (BoB) to record and playback video and CAN data as if the camera system was used in an actual automobile. The aim of this thesis has been to develop a BoB for these camera systems. The work has been divided into three phases; identification of requirements, design of the BoB and implementation of a prototype. The project has addressed four known issues with the currently used BoB; bandwidth, modularity, synchronization and usability. The result is a new BoB which is based on an FPGA connecting to a PC over Gigabit Ethernet. The design is an extendible platform for multiple channels of video, CAN data, other serial data and future extensions. A prototype proves the design concept by successfully recording video for the Autoliv NightVision system onto a PC.</p>

<p>Sammanfattning: Det är minst lika många människor som besöker arrangemang och gudstjänster i kyrkor som besöker idrottsevenemang. Det behövs studiogudstjänster dock sänds det allt färre Tv-gudstjänster direkt från kyrkor och medlen för att göra detta är också på väg att minskas. Många som ser dessa gudstjänster har av olika orsaker inte möjlighet att besöka en kyrka. Detta kan t ex bero på funktionshinder och sjukdom men också att många äldre har svårt att förflytta sig och se gudstjänster live. Ett sätt för kyrkorna att nå ut på bredare front skulle kunna vara att använda sig av Internet som media.</p><p>Syftet med uppsatsen är att genom intervjuer, användningstestning och slutligen prototyptestning, ta fram en lösning för digital överföring av ljud och bild från ett ställe till ett annat via ett IP-nätverk och finna en avvägning mellan det tekniska och användbarheten då användaren har begränsad teknisk kunskap.</p><p>Vid datainsamlingen användes en kvalitativ forskningsprocess med intervjuer och observation som insamlingstekniker. Vid användningstesterna användes observation som metod och testpersonerna uppmanades att tänka högt. Analysen av testerna visade vikten av att minimera inblandning av för mycket teknik i lösningarna då områdeskunskapen hos användare varierar kraftigt.</p>
