Mobile phone for retrieving and playing video

Abstract

A mobile phone includes: a body; an image sensor positioned in the body for imaging an area of a printed substrate and generating image data; a display screen for outputting video; a processor coupled to the sensor, the processor being configured for: retrieving video data based on an identity of the substrate and a position of the mobile phone relative to the substrate, and rendering video output to the display screen; and a memory coupled to the processor.

1 . A mobile phone comprising:
 a body;   at least one image sensor positioned in the body for imaging an area of a printed substrate and generating image data;   a display screen for outputting video;   a processor coupled to the sensor, said processor being configured for:
 retrieving video data based on an identity of the substrate and a position of the mobile phone relative to the substrate; and 
 rendering video output to the display screen, said video output being at least partially based on the retrieved video data; and 
   a memory coupled to the processor.   
     
     
         2 . The mobile phone of  claim 1 , wherein said memory is for storing said video data. 
     
     
         3 . The mobile phone of  claim 1 , wherein said image data identifies the identity of the substrate and the position of the mobile phone relative to the substrate. 
     
     
         4 . The mobile phone of  claim 1 , wherein the processor is configured for retrieving the video data from a remote computer system. 
     
     
         5 . The mobile phone of  claim 1 , wherein the processor is configured for retrieving the video data from the memory. 
     
     
         6 . The mobile phone of  claim 1 , wherein the display screen is a touchscreen. 
     
     
         7 . The mobile phone of  claim 6 , wherein the processor is configured for displaying video playback control icons on the touchscreen, such that video playback is controllable via the touchscreen. 
     
     
         8 . A method of playing video, said method comprising the steps of:
 (a) providing a printed substrate;   (b) operatively positioning a mobile phone relative to the substrate, said mobile phone comprising an image sensor, a processor, a memory and a display screen;   (c) imaging an area of a printed substrate and generating image data using the image sensor;   (d) monitoring an identity of the substrate and a position of the mobile phone relative to the substrate using the image data;   (e) retrieving video data based on the identity of the substrate and the position of the mobile phone relative to the substrate;   (f) rendering video output to the display screen, said video output being at least partially based on the retrieved video data; and   (g) playing video on the display screen.   
     
     
         9 . The method of  claim 8  further comprising the step of:
 controlling video playback via control icons displayed on the display screen. 
 
     
     
         10 . The method of  claim 9 , wherein the display screen is a touchscreen.
