Abstract

A method and system for rating programs, the method including, receiving a sample of viewing logs from a plurality of set top boxes (STBs), determining, from the sample of viewing logs, at least groups of viewers sharing similar interests, and groups of programs sharing similar audience, computing time dynamics of rating distribution for the groups of viewers and the groups of programs, and incorporating at least one of the following into broadcast metadata: the time dynamics of rating distributions of the groups of viewers for each of the groups of programs, rating distributions of the groups of viewers for each of the groups of programs marginalized by time, rating distributions of the groups of viewers for each program marginalized by time, relative sizes of each group of viewers, and a mapping of each program to groups of programs, thereby making the broadcast metadata available to the plurality of STBs for use in computing ratings. Related systems and methods are described.

         20 . A method for determining confidence in viewer presence near a set top box (STB), the method comprising:
 receiving a first remote control signal at the STB;   assigning a level of confidence in viewer presence to be 100% in response to receiving the first remote control signal;   smoothly decreasing the level of confidence in viewer presence over time;   receiving a second remote control signal at the STB; and   setting the level of confidence in viewer presence to be 100%.   
     
     
         21 . The method according to  claim 20  and wherein the decreasing comprises exponential decreasing. 
     
     
         22 . The method according to  claim 20  and wherein the level of confidence in viewer presence drops at the end of a broadcast program. 
     
     
         23 . The method according to  claim 20  and wherein the signaling comprises electrical appliance remote control signaling. 
     
     
         24 . The method according to  claim 23  and wherein the signaling comprises TV remote control signaling.
