Patent ID: 7991270

Claim:
A non-transitory recording medium on which playlist information is recorded, wherein the playlist information includes main-path information and sub-path information, the main-path information specifies, among a plurality of digital streams, one digital stream as a main stream, and defines a primary playback section on the main stream, the sub-path information specifies, among rest of the plurality of digital streams, one digital stream as a substream, and defines, on the substream, a secondary playback section which is to be synchronized with the primary playback section, the main-path information further includes a stream table showing at least one pair of elementary streams which are allowed to be simultaneously played back, the pair of elementary streams being made up of at least one of a plurality of elementary streams multiplexed into the main stream and at least one of a plurality of elementary streams multiplexed into the substream, the stream table includes a plurality of stream entries, each of which lists a packet identifier indentifying a TS packet that is allowed to be simultaneously played back, from among TS packets constituting any of the plurality of elementary streams each of the main stream and the substream is a TS packet sequence having a plurality of TS packets each of which has an arrival time stamp attached thereto, a total data size of the pair of elementary streams to be decoded at once per unit time is less than or equal to 48 Mbits, and the total data size per unit time is calculated in a range covered by a window that is a verification frame having a one-second duration on a time axis of the arrival time stamps, and the total data size is less than or equal to 48 Mbits regardless of which time point on the time axis a starting point of the window is present at.
