Abstract: A system can include a controller that employs an application interface to create and manage resources for encoding or transcoding an input media asset. The resources can include a media splitter to divide the input media asset into a plurality of media blocks. A media analyzer can analyze separately media content in each of the media blocks to determine respective encoding parameters for each of the media blocks based on a complexity for each of the respective media blocks. A plurality of encoders can encode or transcode, in parallel with each other, each of the media blocks based on the determined encoding parameters to generate an encoded media file in a target format.

Abstract: A method is provided in one example and includes receiving common format media including timed metadata associated with a timed metadata event. The method further includes extracting timed metadata information from the timed metadata, and generating a manifest corresponding to the common format media including the timed metadata information. The timed metadata information includes an indicator of a start time and an indicator of a duration of the timed metadata event. The method further includes generating a common format asset including the manifest.

Abstract: A method is provided in one example embodiment and includes generating a key associated with a virtual asset associated with content to be provided to a client device, where the key indicates at least one parameter for accessing the content; generating the virtual asset; receiving a request for the content; identifying a format being requested for the content; using the virtual asset to identify common format content to be retrieved and to identify the key; using the key to retrieve the common format content; and transforming the common format content such that it can be delivered to the client device in the format that was requested.

Abstract: A method is provided in certain example embodiments, and may include receiving source timed text data and an associated time stamp, and rendering a representation of the received source timed text data within a textual array. The textual array includes at least one row having textual data associated with the received source timed text data contained therein. The method may further include producing at least one data document including row data associated with one or more rows of the textual array when the textual data of the at least one row has changed from a previously rendered on-screen representation of previously received source timed text data. The row data includes a change in textual data for one or more rows from a previously produced caption data document.

Abstract: A method is provided in certain example embodiments and may include evaluating a first video stream being encoded by a first encoding element, where the first video stream is provided at a first bit rate. The method may also include evaluating a second video stream being encoded by a second encoding element, where the second video stream is provided at a second bit rate. The method may further include providing an output that is reflective of a time synchronization and a frame alignment for a plurality of frames within the first video stream and the second video stream.

Abstract: A method is provided in one example embodiment and includes receiving a request for video content from a client device and accessing a common format representation for a requested chunk within the video content. The common format representation is provided in one or more files that include metadata indicative of one or more counters. The method can also include using the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and using the predicted size of the output to initiate transmitting at least a portion of a response to the client.
