Systems and methods for enabling playback control functions of a media player are disclosed. For example, a user of a client device receiving streaming playback of a video stream may perform rewind and fast forward control functions. The client device may implement these playback control functions by retrieving an enhanced playback segment. Using the enhanced playback segment, the media player may display selected frames at a predetermined interval while maintaining a visual cadence that is pleasing to a viewer. In the described embodiments, a client device may render a video stream, receive a command to control a fast forward or rewind playback mode for the video stream, and retrieve, from a distribution server or associated edge cache, one or more enhanced playback segments adapted to implement the user command.

A Personal TV System receives a plurality of video segments constituting a TV program and information describing each segment, and controls the display of the segments to a viewer in accordance with preferences of the viewer and with the description of each segment. Segments may be omitted or replaced with substitute segments. The viewer may review his preferences and edit or replace them. In a multi-viewer household, the system may prompt a viewer to confirm her preferences. A TV program may contain interactive segments, and when the viewer chooses to interact with a particular segment, the system automatically stores all subsequently received segments for later viewing while the viewer interacts with the selected segment. The system may present TV program choices to the viewer selected and arranged in accordance with her preferences.

The subject disclosure is directed towards providing a web application with access to hardware accelerated graphics. A rendering format for a set of video frames is established. A graphics component, which is coupled to a graphics device and associated with an unsupported file type, is identified. The graphics component generates image data compromising the hardware accelerated graphics. When the web application requests a set of video frames, the image data is transformed into the set of video frames in accordance with the format. Then, the set of frames is communicated to a display device.

A content utilization support method executed by a computer, including detecting a section of a content based on operation information on the content and user information, the detected section being a section whose play frequency by single user is more than a predetermined value, comparing a first distribution that is a distribution of attribute information of users in a first group and a second distribution that is a distribution of attribute information of users in a second group, the first group being a group of the users whose play frequency of the detected section is more than predetermined value, the second group being a group of the users whose play frequency of the detected section is equal to or less than predetermined value, and outputting information that indicates the detected section and attribute information whose difference between the first distribution and the second distribution is larger than a predetermined threshold.

Power aware adaptation for a power aware video streaming system may be based on the complexity information conveyed in different ways. A complexity level of a data stream, such as a video data stream, may be selected as a function of a remaining battery power of a wireless transmit/receive unit (WTRU) and on a state set of a plurality of state sets that may be stored and/or managed by the WTRU. These state sets may correspond to, for example, different content sources and/or different complexity estimation algorithms and may be used to select the complexity level of the data stream. The data stream may then be received at the selected complexity level. The complexity level and/or a bitrate of the data stream may be adapted to accommodate, for example, the remaining battery power and/or other circumstances. The adaptation may be customized according to the objectives of use cases.

A near real time content streaming system can use a playlist file, in one embodiment, that includes an indicator of the type of content represented by the playlist file. The type can be indicated by a parameter, such as Video on Demand (VOD) or live, or event, that specifies the type of playlist file, and a client device can process the playlist file based upon the type of playlist file indicated by the parameter. For example, the client device, after determining the type of playlist from a playlist file can make efficiency optimizations when processing the playlist file. For example, the client, knowing the playlist file is a VOD playlist, can save the previously used variant playlist when switching to a new variant playlist rather than discarding the previously used variant playlist.
