    Abstract: Reconciling Adaptive Bitrate (ABR) segments across redundant sites may be provided. First, a working manifest may be set to match a primary downstream manifest and the working manifest may be updated using an auxiliary downstream manifest. Next, first segments missing from the working manifest as identified during updating the working manifest using the auxiliary downstream manifest may be copied from the auxiliary downstream manifest to the primary downstream manifest. The working manifest may then be updated using a primary upstream manifest. And then second segments missing from the working manifest as identified during updating the working manifest using the primary upstream manifest may be copied from the primary upstream manifest to the primary downstream manifest.

    Abstract: A method is provided in one example and includes receiving media content including timed metadata, generating a common format asset including the timed metadata and a timed metadata index including at least one reference point corresponding to the common format asset. Each reference point includes state context information of the timed metadata at a particular instance of time. The method may further include receiving a request for the timed metadata from a particular client device, and retrieving a determined amount of the timed metadata from the common format asset using the timed metadata index. In a particular example, the determined amount of the timed metadata is an amount sufficient to display a current timed metadata context corresponding to the request.

    Abstract: A method is provided in one example and includes receiving first synchronization information associated with a first encapsulated output, receiving second synchronization information associated with a second encapsulated output, and determining whether the first encapsulated output and the second encapsulated output are in synchronization based upon the first synchronization information and the second synchronization information. The method may further include, when the first encapsulated output and the second encapsulated output are determined to out of synchronization, generating corrected synchronization information, and sending the corrected synchronization information to an encapsulator generating at least one of the first encapsulated output and the second encapsulated output.

    Abstract translation: 在一个示例中提供了一种方法，并且包括接收与第一封装输出相关联的第一同步信息，接收与第二封装输出相关联的第二同步信息，以及基于第一封装输出，确定第一封装输出和第二封装输出是否同步 同步信息和第二同步信息。 该方法还可以包括：当第一封装输出和第二封装输出被确定为不同步时，产生校正后的同步信息，并将修正后的同步信息发送到封装器，该封装器产生第一封装输出和第二封装输出中的至少一个封装 输出。

    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.

    Abstract: Content delivery network storage may be provided. A first proxy module may receive a first content object request from a first user device. The first content object request may correspond to a content object. Next, the first proxy module may send the first content object request to a first cache module. The first cache module may then obtain the content object corresponding to the first content object request from an object store. The object store may be shared by a plurality of cache modules including the first cache module. The first proxy module may then receive, from the first cache module, the obtained content object. The first proxy module may send the content object to the first user device.
