摘要： Advertisements are often presented in the context of a media content viewing experience. Advertisement presentation may be intrusive or subtle. In many instances, users may be interested in particular advertisements but may not want to disrupt a media content viewing experience by launching an advertisement window, opening an advertisement application, or otherwise being redirected to another piece of content. Consequently, mechanisms are provided to allow a user to identify advertisements or save advertisement interests for presentation at a later time. Saved advertisement interests can be used to inform future advertisement and/or content suggestions, and the user can be presented with selected advertisements within an application or through external mechanisms.

摘要： Mechanisms are provided to allow for improved media content navigation. Metadata such as closed captioning, social media content, and tags associated with various media segments are analyzed to allow identification of particular entities depicted in the various media segments. Image recognition and audio recognition algorithms can also be performed to further identify entities or validate results from the analysis of metadata.

摘要： Mechanisms are provided for replacing default advertisement streams in a media stream with replacement advertisement streams. User profile information is obtained for a particular user and/or device. A default advertisement stream is identified and replaced with advertisement streams selected using the user profile information. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream while customizing media streams for particular users.

摘要： Described herein are techniques and mechanisms for providing a lean private copy of media content. According to various embodiments, a private copy of a media content item may be made specific to a user account. For example, to use a private copy of a media content item to present that media content item, a client machine may need to first perform operations such as account authentication, content licensing, and device-based DRM. The private copy of the media content item may be significantly deduplicated such that the actual size on disk of the private copy is small relative to the size of the uncompressed media content item. The private copy of the media content item may include reference information which maps the user account associated with the copy to data files associated with the recording.

摘要： Media content typically includes closed captioning information such as subtitled in domestic and foreign languages. Techniques and mechanisms provide that closed captioning information may be toggled on/off using menu options and preferences as well as automatically managed by intelligently monitoring the environment surrounding a device. Device sensors such as microphones and vibration monitors determine the noise level of an environment as well as the spectral characteristics of the noise to determine whether the noise profile would interfere with the video playback experience. A particular environmental noise profile could automatically trigger the display of closed captioning information or present an easy access, otherwise unavailable toggle to display closed captioning information associated with a video stream.

摘要： Mechanisms are provided to allow efficient delivery of content through a content delivery network (CDN) without taxing an origin server while maintaining fine grained location based access control. Requests to a CDN are augmented with quantized and non-quantized versions of location information. A CDN can use quantized location information in a URI to identify and return content if content corresponding to the URI is available in cache. If the content is not available in cache, the CDN can contact an origin server to obtain a result for the request using non-quantized location information. The origin server examines the non-quantized location information to determine whether to respond to the client request with content. The origin server examines the area corresponding to the quantized location information to determine whether the content should be cached at the CDN.

摘要： Mechanisms are provided to manage media stream transmissions at a content server. A content server detects that a user on a device such as a mobile device has stopped playing a live media stream. The content server maintains information associating the user with the media stream and time information. When the content server detects that a user wishes to resume playing a media stream, the user can continue viewing the media stream from where stoppage occurred. In many instances, the content server stores many hours of live media stream data and allows a user to select a particular starting point.

摘要： Mechanisms provide intermediate key frame animation during a media seek. A streaming server receives a seek request from a client device while the streaming server provides the client device with a media stream. The seek request is made when the media stream is playing at an initial location and the seek request includes a request to play the media stream from a seek location. In some embodiments, intermediate key frames before the seek location are identified. In other instances, intermediate key frames between the initial location and the seek location are identified. These intermediate key frames are provided to the client device for display before the media stream begins playing at the seek location.

摘要： Techniques and mechanisms described herein facilitate the management of digital rights for media content item presentation. According to various embodiments, a request for a content decryption key may be received at a media application implemented at a computing device. The request may be transmitted by a media content player implemented at the computing device. The request may be transmitted in accordance with a designated key exchange protocol. A license for an encrypted media content item corresponding with the requested content decryption key may be identified at the media application. Based on information included in the license, encrypted key material may be decrypted to create the requested content decryption key via a processor at the computing device. The requested content decryption key may be provided to the media content player.
