TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What do you need in addition to the LaserDisc in order to experience surround sound?, Context: Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser. A fully capable LaserDisc playback system includes a newer LaserDisc player that is capable of playing digital tracks, has a digital optical output for digital PCM and DTS audio, is aware of AC-3 audio tracks, and has an AC-3 coaxial output; an external or internal AC-3 RF demodulator and AC-3 decoder; and a DTS decoder. Many 1990s A/V receivers combine the AC-3 decoder and DTS decoder logic, but an integrated AC-3 demodulator is rare both in LaserDisc players and in later A/V receivers.

SOLUTION: playback equipment

PROBLEM: Where does the name originate?, Context: The first mention of the name "Rajasthan" appears in James Tod's 1829 publication Annals and Antiquities of Rajast'han or the Central and Western Rajpoot States of India, while the earliest known record of "Rajputana" as a name for the region is in George Thomas's 1800 memoir Military Memories. John Keay, in his book India: A History, stated that "Rajputana" was coined by the British in 1829, John Briggs, translating Ferishta's history of early Islamic India, used the phrase "Rajpoot (Rajput) princes" rather than "Indian princes".

SOLUTION: in James Tod's 1829 publication Annals and Antiquities
