“…Currently, more and more digital television content is offered by service providers using computer networks with the Internet Protocol, the so-called IPTV, which is currently under consideration for ITU-T standardization efforts also [73]. Dependent on the service that provider companies offer, the users may select specific movies (called video-on-demand) or record the TV program to a Personal Video Recorder (PVR) [112], which can also be used as a home server to stream media data to TV devices in the home environment. Service providers may offer such PVR in combination with proprietary set-top boxes to allow access via the closed network of this provider only.…”

At the time being, multimedia services using IP technology are a hot topic for network and service providers. Examples are IPTV, which stands for television broadcast over a (mostly closed) network infrastructure by means of the IP suite, or video on-demand, which allows for watching selected movies via Internet on TV devices or computers in the home. Technically, these services can be classified under the notion of streaming. A server sends media data in a continuous fashion to one or several clients, which consume data portions as soon as they arrive, mostly displaying them also. By using a feedback channel customers may influence the play-back, since they may watch programs time-shifted or pause the program. An enhancement of such streaming services is to watch those movies together with a group of people on several devices in parallel, independent from the location of the other group members. Similar approaches have been developed using IP multicast, for example for distributing lectures or conference talks to a group of listeners. However, users cannot control the presentation: pausing or skipping of more unimportant parts is impossible. Moreover, the streaming presentation is announced by means outside the application instead of adding others to the session directly within the application. The costream architecture developed in this works offers a collaborative streaming service without these limitations: People may retrieve movies, join others watching a movie or invite others to such a collaborative streaming session. Participants of a collaborative streaming session can control the movie presentation like they do on a DVD player. Dependent on the desired course of the session the control operation is executed for all users, or the group is split into subgroups to let watchers follow their own time-lines. For this, a group management controls access to session control operations by means of user roles. Separate from the group management, the so-called association service provides for streaming session control and synchronization among participants. This separation of duties is advantageous in the sense that standard components can be used: For group management, SIP conferencing servers are suitable, whereas session control can best be handled using RTSP proxies as already used for caching of media data. Eventually, the evaluation of this architecture shows that such a service offers both low latency for clients and an acceptable synchronization of media streams to different client devices. Moreover, the communication overhead compared to usual conferencing or streaming systems is very low.

“…Commercially available Personal Video Recorders (PVR) such as HDD-enabled DVD [1] or Blu-ray Recorders, can already record several hundred hours of standard definition content and over fifty hours of High-Definition content. As storage capacities grow rapidly every year, it will be essential to develop rapid browsing technology that satisfies the consumer's need to get to a desired video segment quickly.…”

We have extended our sports video browsing framework for personal video recorders, such as recordable-DVD recorders, blu-ray disc recorders and/or hard disc recorders, to music segment detection. Our extension to Japanese broadcast music video programs consists of detecting audio segment boundaries such as conversations with guests followed by music/song etc. Our proposed system first identifies the music/song scenes using audio analysis, and then adjusts the start/end position by detecting video shot changes, so as to achieve accurate detection of the music segment thus enabling rapid browsing. Our preliminary results indicate that our audio-only summarization with scene change support works well for music video content. We can therefore integrate the enhancement into our product at a low computational cost.
