Abstract: The present disclosure describes systems and methods for retrieving and accessing, through a media player rendering a first piece of media, other pieces of media. Metadata may be provided with media content items, such as media files containing media streams. At predefined points in time in the video, the metadata is accessed and any other media associated with that frame of video are determined therefrom. This associated media is then displayed to the user automatically. The associated media may be an advertisement related to what was being shown in that frame, or point in the playback, or additional info about what was being shown in that frame, or point in the playback. The systems and methods can be used for displaying advertisements on web pages or in media players with limited display area.

Abstract: Methods and systems of presenting video on a computer display having a visible display area are hereby disclosed. At least one video input is received from a video source. A video corresponding to the video put is displayed in a viewing region of the display. The viewing region can be of a size that occupies a fractional portion of the visible display area. The video can be displayed in a translucent fashion so that the video is visible and so that other content displayed on the computer display is visible through the video. After a period of user inactivity, the video can be displayed in an opaque fashion so that other content displayed on the computer display is hidden under the video.

Abstract: A diffusional gas transfer system and method having a membrane disposed between a first gas domain and a second gas domain. The first gas domain includes a first mechanism for directing a first environmental gas flow transversely over and in contact with a first surface of the membrane. The second gas domain includes a second mechanism for directing a second environmental gas flow transversely over and in contact with a second surface of the membrane. The membrane is a diffusional gas transfer medium having a multiplicity of tortuous pathways extending from the first surface of the membrane to the second surface of the membrane. The void volume fraction of the membrane is at least 0.2. The membrane is capable of substantially blocking the transfer of particles from the first gas domain to the second gas domain, while permitting the diffusion of gases between the first and second gas domains, and the first gas domain is maintained at a pressure higher than the second gas domain.
