Abstract: Systems and methods for improved video formats used in delivery and playback are presented. According to an embodiment, the movie package format contains tiers that provide for multiple sets of movie variations that are individually selectable for transfer to a device for local playback. A locally stored movie package may contain any subset of available tiers for a movie. Non-resident tiers can be discovered and downloaded into the movie package as needed or when available. Tiers, and other movie files may be updated or added to the movie package at any time. Then users can request updates or the updates can be pushed to the user without affecting the previously downloaded files.

Abstract: Techniques are described for synchronizing multiple time-based data streams with independent clocks wherein relationships between clock rates of timing devices associated with the time-based data streams are determined, and based on these relationships, times in at least one of the time-based data streams may be translated to times in any of the other time-based data streams despite the data streams having independent clocks.

Abstract: An encoding system may include a metadata manager, a key manager, and an encoder. The metadata manager may interface with one or more metadata sources to determine whether to include a metadata item from the one or more metadata sources. The key manager may determine whether the metadata item can be represented using one of already-allocated keys or an inline key must be used to represent the metadata item. The encoder may encode the metadata. If an inline key must be used to represent the metadata item, the encoder may associate the inline key and the type of the metadata item to the media file, and the encoder may encode the metadata item using the inline key in the media file.

Abstract: Techniques are disclosed for addressing “stereoscopic window violations” in stereoscopic multimedia content. Stereoscopic window violations result in the stereoscopic effect becoming “broken” for the viewer and may occur, e.g., when the left and right stereo eye views in the stereoscopic content are mismatched. Stereoscopic mismatch often occurs at the edges of the left and right eye video image frames (wherein, e.g., a depicted shape may become cut off for a left eye view but not a corresponding right eye view). According to the techniques disclosed herein, rather than permanently masking or otherwise editing the stereoscopic video content to account for any window violations, accompanying stereoscopic window violation metadata information may be generated for the stereoscopic video, which may be used to define a particular geometry for each left and right eye video image frame pair, and used at playback time to crop, mask, or otherwise modify the video image frames.

Abstract: System and methods for storing streamed media data to memory for future playback are provided. A device may stream media data associated with a movie over a network connection. The data streamed to the device will be saved to device memory and will then be playable offline. A manifest associated with the media data will be downloaded to the device and modified to reflect the location of the locally stored media data. During subsequent playback of the media data, the manifest will indicate that at least a portion of the media data exists in local memory. Some portions of the media data not stored locally may be subsequently retrieved from a remote source. The stored data may be updated or added to as necessary.
