Abstract
According to one embodiment, an electronic apparatus receives a first packet group of a stream of content data. The apparatus includes a first detector, a second detector and an index generator. The first detector detects a first packet of the first packet group, the first packet including program information. The second detector detects a start packet of a second packet group from the first packet group, the second packet group carrying a randomly accessible video frame. The second detector detects a time stamp from the start packet or another packet having the same packet ID. The index generator generates index information indicating a storage position of the first packet in a buffer and the time stamp.
