1. A method implemented by one or more modules of a client device, the method comprising:

  • receiving a stream of content from a distribution system that is to be recorded locally in memory at the client device using a media sink;

    detecting an interruption of receipt of the stream of content from the distribution system that results in a loss of at least some of the content of the stream;

    determining minimum content stream characteristics based on a predetermined threshold that enable the media sink to continue recording the stream of content to the memory of the client device;

    generating a stream of supplemental content at the client device that has at least the determined minimum characteristics to supplement the loss of the at least some content, including generating program clock reference (PCR) values for the stream of supplemental content and configuring the generated PCR values according to an internal clock maintained at the client device to follow PCR values of the stream of content;

    combining the supplemental content with portions of the stream of content that are received from the distribution system to form an uninterrupted stream of content, the supplemental content filling a gap in the stream of content caused by the interruption; and

    using the media sink to record the uninterrupted stream of content in the memory of the client device.
