Apparatus and method for supporting picture-in-picture type time shifting
First Claim
1. A method for supporting a picture-in-picture (PIP) type time shifting comprising:
- a first display step of receiving a plurality of broadcasting programs received through a broadcasting network, and displaying the respective live broadcasting programs through a PIP structure on a screen;
a second display step of selectively storing in a storage section one among the plurality of broadcasting programs displayed at the first display step, and selectively reproducing the stored broadcasting program through the time shifting to display the stored broadcasting program on the screen; and
a third display step of displaying through the PIP structure on the screen a plurality of currently received other live broadcasting programs simultaneously with the second display step.

Abstract
Disclosed is a method for supporting a picture-in-picture (PIP) type time shifting which enables a live broadcasting picture or a time-shifted SD stream to be viewed simultaneously with a time shifting of another SD stream on a PIP screen. The method includes a first display step of receiving a plurality of broadcasting programs received through a broadcasting network and displaying the respective live broadcasting programs through a PIP structure on a screen, a second display step of selectively storing in a storage section one among the plurality of broadcasting programs displayed at the first display step and selectively reproducing the stored broadcasting program through the time shifting to display the stored broadcasting program on the screen, and a third display step of displaying through the PIP structure on the screen a plurality of currently received other live broadcasting programs simultaneously with the second display step.

4. An apparatus for supporting a PIP type time shifting comprising:
-
an NTSC/PAL encoding section for compressing and encoding an analog broadcasting signal received through a broadcasting network;
a demux section for selecting one of the analog broadcasting signal outputted from the NTSC/PAL encoding section and a digital broadcasting signal inputted through the broadcasting network;
a packet identifier (PID) filter section for filtering a plurality of TP stream packets to discriminate packets which coincide with packet identifiers (PIDs) desired to be recorded;
a storage section interface for enabling the TP stream packet selectively filtered through the PID filter section to be stored in a storage device with desired information added thereto, and for enabling the desired TP stream among the TP streams stored in the storage device to be searched and read out; and
a remux section for supporting a PIP function by selecting the desired stream among the TP stream packets transmitted for a live broadcast or the TP stream packets read out from the storage device, and converting the selected stream into the TP stream packets again. - View Dependent Claims (5, 6, 7, 8)
