DTS Inc. said late Monday that it swung to a first-quarter profit, crediting a jump in demand for high definition components.

For the quarter ended March 31, DTS earned $1.3 million (7 cents per share), compared to a loss of $765,000 (- 4 cents) in the same period a year earlier. However, it fell short of analysts' expectations of 13 cents per share profit, according to Thomson Financial.

Revenue for the Agoura Hills-based maker of audio parts for speakers, DVD players and computers rose 21 percent to $15.2 million beating Wall Street predictions of $14.4 million.

DTS attributed the revenue increase to growth in the high definition optical media markets, mainly related to game consoles and DVD players which accounted for 21 percent of total sales, compare to 5 percent the same period last year.

Shares in DTS rose 11 percent to $31.61 in early trading Tuesday.
