ESPN Aims to Deliver Discrete Left and Right 3D Feeds
August 12, 2010
BRISTOL, CONN.: Frame-compatible
distribution is the 3DTV delivery method du
jour, but ESPN would like to step it up.
Executives at ESPN are looking into delivery discrete left/right eye HD
feeds to their programming distributors, according to John Moulding over at VideoNet.
Content produced in 3D is captured in those discrete left/right eye views,
and often sent back to a broadcast operations center that way. Discrete JPEG2000-compressed
views were sent from stadiums to the International Broadcast Centre during the
summer’s 2010 FIFA World Cup soccer games. ESPN is likewise doing contribution
in discrete views, Moulding said.
However, the material encoded into an MPEG-2 HD SDI frame-compatible output for
delivery to cable and satellite operators. Frame-compatible delivery is
preferred because it works with infrastructures equipped for HD without further
transcoding. ESPN’s senior director of technology, Jon Pannaman, told Moulding
that the network wants to deliver discrete left/right eye views as soon as it
becomes “practical.” That way, the distributors can decide if they want to
transmit frame-compatible side-by-side views, or a more advance format.
