Toshiba Corp. announced Tuesday it will completely shut down its HD DVD operations, ending a battle with Sony Corp.'s rival Blu-ray system to become the industry standard for next-generation DVDs.

The move means the Blu-ray format, also supported by major electronics makers Matsushita Electric Industrial Co. and Sharp Corp., will become the next-generation standard for DVD players.

Toshiba said the shutdown will be completed by around the end of March.
