Discovery Communications, which operates the Discovery Channel, said Tuesday that it will be the first television outlet to release programs on high-definition DVDs. Its Discovery Atlas: China Revealed, set to air on Oct. 1, will be available on the HD DVD and Blu-ray formats later in the month at Discovery's retail stores, the company said in a statement. The DVD package will be supplemented with a number of online extras, including video shorts about Chinese culture, the company said.
