  • User profiling for pre-fetching or caching in a catch-up TV network

  • Conference paper (peer-reviewed)abstract
    • We investigate the potential of different pre-fetching and/or caching strategies for different user behaviour with respect to surfing or browsing in a catch-up-TV network. To this end we identify accounts and channels associated with strong or weak surfing or browsing respectively and study the distributions of hold times for the different types of behaviour. Finally we present results from a request prediction model and a caching simulation for the different types of behaviour and find that the results are relatively similar.

  • An Attempt of Mimicking TV News Program with Full 3DCG-Aiming at the Text-Generated TV System -
  • 2016
  • In: 2016 Ieee International Symposium On Broadband Multimedia Systems And Broadcasting (BMSB). - 9781467390446
  • Conference paper (peer-reviewed)abstract
    • We have been studying and developing a new television system based on a methodology which delivers text-based scripts through the Internet representing visual contents instead of transmitting visual content in a format of video data. Such a Text-Generated TV System is achieved by the technology called TVML (TV program Making Language) enabling to create TV-program-like computer graphics animation automatically from script. One of the problems in our development is how to establish the scheme of TV program production with TVML to get quality contents like in a real TV broadcast. Our approach to the problem is to analyze the real TV program and to mimic it with TVML. We first choose a reference TV program then analyze it in many aspects. Based on the acquired knowledge, we then transfer those findings to CG production made using TVML to make a copy of the original TV show as faithful as possible. The objective of the attempt is to reveal the essential elements which would be needed to obtain a full-CG TV program with quality. In this paper, we describe the mimicking process of the news show, the result of the TVML production with a comparison to the original and the evaluation result that we conducted with testers. Finally, we discuss the pros and cons of the CG production applied to produce news show and have shed light on the problems.
