Abstract: 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.

Abstract: 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.

Abstract: Techniques and mechanisms described herein facilitate consecutive live ad insertion for live media streams. A live media stream is received and played at a client device. A first ad indicator in the live media stream, indicating a first start point for a first ad period, is detected. Upon reaching the first start point, reception of the live media stream is paused and one or more first replacement ads are played instead of one or more first original ads. Before the first ad period ends, a small portion of the live media stream is fetched in order to detect the presence of a second ad indicator indicating the presence of a second, consecutive ad period in the live media stream. Upon detecting the second ad indicator, one or more second replacement ads are played during the second ad period.

Abstract: The embodiments of the present invention relate to methods and arrangements for accomplishing trick modes. This is achieved by assigning samples within a track to sample groups, wherein all samples within a sample group belong to one temporal level and by allowing the client to access one temporal level independently of lower temporal levels. In this way, the flexibility for the client regarding play out of different frame rates is increased which can result in a lower bandwidth utilization.

Abstract: For streaming data in a mobile communication network, a descriptive file of a stream is provided. The descriptive file comprises a list of delivery source identifiers, e.g. URIs, for unicast delivery of data segments of the stream. A broadcast indicator is selectively added to the descriptive file so as to indicate whether broadcast delivery of the data segments is available. Adding the broadcast indicator and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

Abstract: Techniques and mechanisms described herein facilitate the management of virtual encoding format converters for live media content streams. A media content system may employ potentially many converters to encode potentially many live video streams. When supporting many live video streams, there may be some streams that are not being viewed by anyone at a particular time. In some such situations, a virtual encoding format converter encoding a live media content stream that is not being viewed may be disabled. Then, live video content associated with the live video stream may be stored in a buffer and updated as new live video content is received. When a user transmits a request to view a stream for which the encoder has been disabled, an format converters for the requested video stream may be enabled. The buffered data may be used to quickly initialize the encoder.

Abstract: Techniques and mechanisms described herein facilitate the management of encoders for live media content streams. A media content system may employ potentially many encoders to encode potentially many live media content streams. When supporting many live media content streams, there may be some channels that are not being viewed by anyone at a particular time. In some such situations, an encoder encoding a live media content stream that is not being viewed may be disabled. Then, live media content associated with the live media content stream may be stored in a buffer and updated as new live media content is received. When a user transmits a request to view a channel for which the encoder has been disabled, an encoder for the requested channel may be enabled. The buffered data may be used to quickly initialize the encoder.

Abstract: For streaming data in a mobile communication network, a descriptive file (100) of a stream (200) is provided. The descriptive file (100) comprises a list (110) of delivery source identifiers, e.g. URIs, for unicast delivery of data segments (210) of the stream. A broadcast indicator (120) is selectively added to the descriptive file (100) so as to indicate whether broadcast delivery of the data segments (210) is available. Adding the broadcast indicator (120) and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

Abstract: Described herein are techniques for facilitating combined broadcast and unicast delivery of content. According to various embodiments, a media stream from a content provider may be received at a unicast server and at a broadcast server. The media stream may comprise a plurality of media stream fragments. A relative delay may be introduced into the media stream at the broadcast server such that media stream fragments transmitted from the broadcast server are delayed relative to media stream fragments transmitted from the unicast server. The media stream fragments may be transmitted to a user device. The user device may be operable to switch between receiving the media stream fragments from the unicast server and the broadcast server.
