Media type

Abstract: Creating and displaying an adaptive menu structure for media files. The invention includes authoring software to create the menu structure to enable a user to navigate the media files using a media player. The invention also includes filtering software to adapt the created menu structure to display menu information on a display associated with the media player as a function of a media type associated with the media player. In one embodiment, the invention is operable as part of a compressed media format having a set of small files containing metadata, menus, and playlists in a compiled binary format designed for playback on feature-rich personal computer media players as well as low cost media players.

Abstract: Recommender systems have become a popular and effective means to manage the ever-increasing amount of multimedia content available today and to help users discover interesting new items. Today’s recommender systems suggest items of various media types, including audio, text, visual (images), and videos. In fact, scientific research related to the analysis of multimedia content has made possible effective content-based recommender systems capable of suggesting items based on an analysis of the features extracted from the item itself. The aim of this survey is to present a thorough review of the state-of-the-art of recommender systems that leverage multimedia content, by classifying the reviewed papers with respect to their media type, the techniques employed to extract and represent their content features, and the recommendation algorithm. Moreover, for each media type, we discuss various domains in which multimedia content plays a key role in human decision-making and is therefore considered in the recommendation process. Examples of the identified domains include fashion, tourism, food, media streaming, and e-commerce.

Abstract: Methods and apparatus are provided for establishing a conference based on the presence or preferences (or both) of one or more invitees. The presence of each invitee is evaluated on one or more devices. A media type is selected based on the presence information. User preference information may be evaluated for those invitees who are not currently present on a device. The selected media type for the conference may optionally be required to support the requirements of the conference, such as document sharing or video links. In this manner, the same communication application can trigger conferences of different media types (where the selected media type is most likely to lead to the successful establishment of the conference). In addition, the present invention allows a media type to be selected that will be more likely to lead to the successful establishment of a conference.

Abstract: Zstandard, or "zstd" (pronounced "zee standard"), is a data compression mechanism. This document describes the mechanism, and registers a media type and content encoding to be used when transporting zstd-compressed content via Multipurpose Internet Mail Extensions (MIME). Despite use of the word "standard" as part of its name, readers are advised that this document is not an Internet Standards Track specification, and is being published for informational purposes only.
