Abstract
A device receives a request for an advertisement from a set-top box (STB) displaying television content in a high definition format, and provides, to the STB, the advertisement in a standard definition format, where the high definition format includes a resolution higher than a resolution of the standard definition format. The device also determines whether the STB converts the advertisement from the standard definition format to the high definition format. When the STB fails to convert the advertisement from the standard definition format to the high definition format, the device generates a first error code and instructs the STB to continue to display the television content, without interruption, in the high definition format.
