1. A television system, comprising:
- an input for receiving signals including video content from one or more external sources, said signals being in one of a lower definition format and a higher definition format;
circuitry for enabling display of said video content in one of a lower definition mode and a higher definition mode of said television system;
circuitry for switching said television system between said lower definition mode and said higher definition mode;
a memory for storing video content corresponding to an electronic program guide demonstration; and
wherein said television system automatically switches from said higher definition mode to said lower definition mode in response to an activation of said electronic program guide demonstration while said signals received at said input are in said higher definition format and not in said lower definition format, and automatically switches back from said lower definition mode to said higher definition mode in response to one of said electronic program guide demonstration being completed and a predetermined time period having expired.

6. A method for operating a television system, comprising:
-
receiving, at an input of said television system, signals including video content from one or more external sources, said signals being in one of a lower definition format and a higher definition format; detecting an activation of an electronic program guide demonstration stored in a memory of said television system; switching said television system from a higher definition mode to a lower definition mode in response to said activation while said signals received at said input are in said higher definition format and not in said lower definition format; detecting one of said electronic program guide demonstration being completed and a predetermined time period having expired; and switching said television system from said lower definition modebackto said higher definition mode in response to said detecting step. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A television system comprising:
-
an input for receiving signals including video content from one or more external sources, said signals being in one of a lower definition format and a higher definition format; circuitry for enabling display of video content in one of a lower definition mode and a higher definition mode of said television system; a controller for switching said television system between said lower definition mode and said higher definition mode; a memory for storing video content corresponding to an electronic program guide demonstration; and wherein said controller automatically switches said television system from said higher definition mode to said lower definition mode in response to activation of the electronic program guide demonstration while said signals received at said input are in said higher definition format and not in said lower definition format, and automatically switches said television system back from said lower definition mode to said higher definition mode in response to one of said electronic program guide demonstration being completed and a predetermined time period having expired. - View Dependent Claims (14, 15, 16)
