DTS Inc. said Tuesday that its board approved a plan to sell its cinema and digital images business.

The Agoura Hills-based company said the move is an effort to focus exclusively on licensing branded entertainment technology to the large and evolving audio, videogame, portable media and broadcast markets. DTS said it has already begun shopping its DTS Digital Cinema and expect a sale this year.

Later in the day, DTS reported a fourth-quarter loss of $5 million (-28 cents per share), a huge departure from its profit of $1.3 million (7 cents per share) for the same period a year earlier. Revenue was also down to $17.5 million, from $17.9 the year before.

For the year, DTS reported a 62 percent dip in net income to $3 million (16 cents per share) but a 3 percent gain in revenue to $78.3 million. Included in the filings was a $3.8 million (20 cents) charge for restructuring costs.

Shares in DTS climbed 18 cents to $23.97 but quickly lost 1.5 percent (47 cents) to $23.60 after the company released its earnings report.
