The device also provides automatic PIP display of the program having the event and a delay of the event so that it is not missed by the viewer.
Claims3
Computer-executable process steps stored on a computer-readable medium, the computer-executable process steps to detect a shape in a video signal including a plurality of different programs and including an MPEG-4 video signal, the computer executable process steps comprising:
- a first receiving step to receive the video signal;
- a second receiving step to receive the MPEG-4 video signal;
- a first decoding step to decode the video signal;
- a second decoding step to decode the MPEG-4 video signal;
- a third receiving step to receive an input from a user defining a shape to be detected in at least one program of the decoded video signal;
- a detecting step for detecting the shape in the decoded MPEG-4 video signal;
- and
- a providing step to automatically provide to a display the program having the detected shape.
An apparatus for detecting a shape in a video signal comprising a plurality of programs, the apparatus comprising:
- a memory which stores process steps;
- and
- a processor which executes the process steps stored in the memory so as (i) to detect, in an MPEG-4 video signal, a shape which as been selected by a user, and (ii) to output automatically to a display upon detection of the shape the program containing the shape.
