Push video on demand is a technique used by a number of broadcasters on systems that lack connectivity to provide true video on demand or by broadcasters who want to optimize their video streaming infrastructure by pre-loading the most popular contents to the consumer device. A push VOD system uses a personal video recorder (PVR) to store a selection of content, often transmitted in spare capacity overnight or all day long at low bandwidth. Users can watch the downloaded content at the time they desire, immediately and without any buffering issue. As content occupies space on the PVR hard drive, downloaded content is usually deleted after a week to make way for newer programs. The limited space on a PVR hard drive means that the selection of programs is usually restricted to most popular content. A new generation of Push VOD solution recently appeared on the market which, by using efficient error correction mechanisms, can free significant amount of bandwidth and that can deliver more than video e.g. magazines, interactive applications.

Famous quotes containing the words push, video and/or demand:
“The essence of being human is that one does not seek perfection, that one is sometimes willing to commit sins for the sake of loyalty, that one does not push asceticism to the point where it makes friendly intercourse impossible, and that one is prepared in the end to be defeated and broken up by life, which is the inevitable price of fastening one’s love upon other human individuals.”
—George Orwell (1903–1950)
“It is among the ranks of school-age children, those six- to twelve-year-olds who once avidly filled their free moments with childhood play, that the greatest change is evident. In the place of traditional, sometimes ancient childhood games that were still popular a generation ago, in the place of fantasy and make- believe play . . . today’s children have substituted television viewing and, most recently, video games.”
—Marie Winn (20th century)
“The small creatures chirp thinly through the dust, through the night.
O mother
What shall I cry?
We demand a committee, a representative committee, a committee of investigation
RESIGN RESIGN RESIGN”
—T.S. (Thomas Stearns)
