Processing and Streaming Video in Browser for Screen Recording
Svačina, Lukáš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
Aim of the thesis is to design and implement unique service based on the newest technologies in web apps fi eld which allows screen recording followed by P2P distribution between participating users using web browser only. Thesis deals with the analysis of modern and coming technologies which allow practical implementation of such a service. It involves obtaining access to the screen source data, its recording, transforming and transmission over the network followed by playing on the other side. Recorded videos are adapted for part by part use in a player with seeking capability. Distributed architecture for data exchange between peers using peer-to-peer connection based on hybrid P2P VoD network provides scalability of the solution. The player allows obtaining the necessary parts of the videos from the current watchers with smooth video playback experience during ongoing transmissions whilst allowing arbitrary video shifting. In consideration of early stages of development or experimental support for some of the APIs needed for this work, research into browsers' support with discussion on realistic applicability nowadays is always performed.

Willingness to pay for streaming services: Evidence from the Czech Republic
Strnadová, Ivana ; Polák, Petr (advisor) ; Kučera, Adam (referee)
The aim of this thesis is to analyze the consumers' willingness to pay for subscription- based video streaming services in the Czech Republic. With the unique data collected via self-developed questionnaire both the willingness to pay and the maximum price that consumers would be willing to pay for such services is examined. Using the logistic regression, variables that have a significant effect on the probability of subscribing were identified. These include the age, education level, preference for original sound and Czech movie production, online payments, purchase of an electronic movie, number of devices used, cinema visits, favouritism of movies over TV shows, satisfaction with the content offered by common broadcasting stations and desire for spatial mobility when accessing video content. Similar results were obtained when predicting the price using OLS. Additionally a previous purchase of a physical medium and the income level were found significant. Based on demand estimation this thesis also suggests that from the provider's perspective the optimal profit maximization price for streaming services should be set in the range from 218 to 283 CZK.
