A system and method provides reduced bandwidth video in an MHP or OCAP broadcast system (100, 200). In one embodiment, the system and method provides end-users (viewers) (109) of an MHP or OCAP broadcast system (100) with a finite sequence of reduced bandwidth data images (133) sampled from a higher bandwidth video source (148). The finite sequence of reduced bandwidth data images (133) are preferably carried in a DVB signal stream (116) for a finite time duration to allow viewers (109) to view the data images (133) at their convenience. In another embodiment, the system and method provides end-users (viewers) (109) of an MHP or OCAP broadcast system (200) with a continuous stream of reduced bandwidth data images (233) sampled from a higher bandwidth digital video broadcast stream (150), preferably for use in a PIP display at the viewer's receiver (103). |
