Abstract

A user interface receives a user selection of a video content item. The video content item is available in a high definition (HD) format and a non-HD format via a broadband network access line. A format selector automatically selects which format of the video content item from the HD format and the non-HD format to retrieve via the broadband network access line. The format is automatically selected based on at least one rule. A receiver receives the video content item via the broadband network access line in the format automatically selected by the format selector. A television display displays the video content item received by the receiver and in the format automatically selected by the format selector.
