    摘要: A method is provided in one example embodiment and includes communicating content to a content receiver, where a first portion of the content has a first drop priority. The method also includes determining a buffer status for a buffer at the content receiver, and adjusting the first drop priority to a second drop priority for a second portion of the content based on the buffer status. In more particular embodiments, the second drop priority can be higher than the first drop priority of the first portion of the content if the buffer is full or above a threshold. Also, the second drop priority can be lower than the first drop priority of the first portion of the content if content in the buffer has not started to render.

    摘要: A method is provided in one example embodiment and includes receiving video data at an adaptive bitrate (ABR) client that includes a buffer; determining whether a buffer level for the buffer is below a target buffer level; applying a random delay for a fetch interval associated with requesting the video data; and requesting a next segment of the video data after the random delay. The random delay can provide for a plurality of fetch times to become decorrelated from each other.

    摘要: A method is provided in one example embodiment and includes generating a bandwidth estimation for an adaptive bitrate (ABR) client; evaluating a current state of a buffer of the ABR client; and determining an encoding rate to be used for the ABR client based, at least, on the bandwidth estimation and the current state of the buffer. A fetch interval for the ABR client increases as the buffer becomes more full, while not reaching a level at which the ABR client is consuming data at a same rate at which it is downloading the data.

    摘要: A technique is provided for rapid channel change (RCC) processing in a programming distribution network. The RCC process herein is configured to transmit unicast stream of packets (“RCC burst”) during a “fast-fill” interval for up to a full duration of the multicast join window, or until it is stopped by a an explicit message sent from the user terminal. The unicast stream of packets is transmitted at a full rate of an access link (i.e., the bottleneck link) on a path to the user terminal beyond an earliest time when the user terminal could join a multicast stream of packets for a new channel requested by the user terminal.
