Sony Pictures Home Entertainment on Tuesday said it will deliver its first seven titles in the high-definition Blu-ray format to retail stores on June 20.

Sony Pictures, a unit of Sony Corp , said the title rollout will coincide with the first commercially available Blu-ray DVD player from Samsung Electronics Co Ltd and a Blu-ray-compatible PC from Sony.

The stakes are huge for Sony, which has developed the standard known as Blu-ray, which is to compete against a rival high-definition standard known as HD-DVD that was developed by a group led by Toshiba.

Among those titles that Sony plans to roll out on June 20 are "50 First Dates," "The Fifth Element," "Hitch" and the "House of Flying Daggers."

Further Blu-ray titles will be released by Sony in coming weeks.

Sony also recently indicated that its Blu-ray player would be delayed because of lack of progress in Blu-ray Disc technology development. Sony's website indicates that the BDP-S1 player will be available "on or about 15 August."
