Methods and apparatus that facilitate channel switching during commercial breaks and/or other program segments
Methods and apparatus that facilitate watching of programming content on a secondary channel during a program segment, e.g., commercial break or program portion which is not of interest to a user, on a primary channel are described. In various embodiments when a user switches to a secondary channel during a program segment, the switch is detected and the program on the primary channel continues to be received and buffered while the content from the secondary channel is output to the display. The program segment on the primary channel may be a commercial break including one or more commercials or a portion of a program identified as a segment in information communicated with the program or via out of band signaling. The end of the segment on the primary channel is detected and the user is notified or automatically switched back to the primary channel at the end of the segment.

4. The set top box of claim 1 , wherein said program segment is said commercial break including one or more commercials, the set top box further comprising:
an interface configured to continue to receive the content corresponding to the first program during the commercial break; and
wherein said processor is further configured to control the set top box to:
i) process the content corresponding to the first program received during the commercial break to detect the end of the commercial break without outputting the content on the display device; and
ii) automatically switch from the second channel back to the first channel in response to detecting the end of the commercial break on the first channel.
5. The set top box of claim 1 , wherein said program segment is said commercial break, and wherein said processor controls the set top box to generate and provide a notification to a user indicating an end of the commercial break on the first channel during display of the content corresponding to said second program received on said second channel, said notification including a visual indication of the end of said commercial break presented on a portion of a display displaying said content corresponding to the second program.
6. The set top box of claim 5 , wherein said processor is further configured to control the set top box to generate and provide a countdown timer showing a count down to the end of said commercial break, as part of generating and providing a notification to the user indicating an end of the commercial break on the first channel.
7. The set top box of claim 1 , wherein said processor is further configured to control the set top box to:
record the second program; and
allow a user to continue viewing the second program form the point the second program was last viewed.
8. A method of operating a set top box, comprising:
outputting to a display content corresponding to a first program being received via a first channel;
receiving user input indicating a channel change request during a first program segment on said first channel to change to a second channel communicating a second program;
continuing to receive the content corresponding to the first program during the commercial break;
switching from outputting to the display the content corresponding to the first program to outputting to the display content corresponding to the second program;
storing some first program content, in a buffer, said stored first program content corresponding to said first program from an end of a commercial break on the first channel, said first program being content that is restricted from being recorded in its entirety;
performing at least one of:
i) providing a notification to a user indicating an end of the first program segment on the first channel during display of content received on said second channel; or
ii) automatically switching from the second channel back to the first channel in response to detecting the end of the first program segment on the first channel; and
outputting stored first program content beginning at the end of said commercial break following a switch from the second channel back to the first channel after the end of said commercial break.
9. The method of claim 8 ,
wherein storing content corresponding to the first program during the commercial break includes pausing a time shift buffer at a point where a commercial ended on the first program channel.
10. The method of claim 9 , wherein the set top box is a digital video recorder; and
wherein the method further comprises: receiving and processing content corresponding to said first program during said commercial break, said receiving and processing content corresponding to said first program during said commercial break including:
receiving content corresponding to said first program via a first tuner tuned to said first channel;
processing the content corresponding to said first program to detect the end of the commercial break; and
using a time shift buffer to pause the first program at the point where the commercial break ended thereby allowing resumption of display of the first program from a point in time right after the commercial break ends.
11. The method of claim 8 , wherein said first program segment is a commercial break, the method further comprising:
providing a notification to a user indicating an end of the commercial break on the first channel during display of the content corresponding to the second program, said notification being a visual indication of the end of said commercial break presented on a portion of a display displaying said content corresponding to the second program.
12. The method of claim 11 , where providing a notification to a user includes:
generating a countdown timer showing a count down to the end of said commercial break.
13. The method of claim 12 , further comprising:
