摘要： Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

摘要： Embodiments of the invention provide for live encoding systems that can replicate a current encoded frame instead of re-encoding said current frame, and then adjust the replicated frame to different bitrates, resolutions, and/or contexts as necessary for the several different adaptive bitrate streams. In addition, various embodiments of the invention can extend a duration of a current frame being repackaged and/or re-encoded. Utilizing these and other techniques, live encoding systems in accordance with embodiments of the invention can more efficiently handle gaps in received data, slower feeding of data, and/or heavy loads on server hardware.

摘要： Systems and methods for automatically generating top level index files for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment of the method of the invention includes receiving a request from a playback device at a playback server, where the request identifies a piece of content, retrieving a list of assets associated with the identified piece of content using the playback server, filtering the list of assets using at least one predetermined criterion using the playback server, generating a top level index file describing each asset in the filtered list of assets using the playback server, and sending the top level index file to the playback device using the playback server.

摘要： Systems and methods for synchronizing the playback of OTT or other time sensitive content on multiple playback devices is disclosed. The systems and methods include receiving time information based on a network time source in the playback devices. The playback clock in each playback device is set based upon the time information. Stream initiation information derived using the time information from the network time source is received by each of the playback device from the media provider. The playback devices use the stream initiation information to adjust the presentation time stamps of the frames of the media content in the stream.

摘要： A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, a complete index that can be used to locate each data chunk in each of these tracks and an abridged index that can enable the location of a subset of the data chunks in each track, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames, a first index that includes information indicative of the location within the file and characteristics of each encoded video frame and a separate second index that includes information indicative of the location within the file of a subset of the encoded video frames.

摘要： Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.
