Abstract
A method, apparatus, and software are provided for using an optically-readable code such as a quick-response (QR) code. The optically-readable code may represent a uniform resource identifier (URI) including parameters that represent a query, such as a query for content and/or other data. The query results may be used to command a content consumption device to record or otherwise obtain an item of content. The optically-readable code may additionally or alternatively be determined based upon a status of the device, such as what content, or portion thereof, is currently being displayed, and/or what error condition is being experienced.
