Abstract:
1. An encoder comprising an input for inputting video signal to be encoded to form an encoded video signal comprising pictures of a first coded video sequence and a second coded video sequence; an encoded picture buffer; a decoded picture buffer; a definer for defining at least one parameter indicative of the temporal reference between the last picture of said first coded video sequence and the first picture of said second coded video sequence, wherein said at least one parameter is signaled in the encoded video signal, and wherein said at least one parameter comprises a parameter indicative of the time duration of a temporal reference difference of one, and a second definer for determining a relative output time for the first picture of said second coded video sequence according to a relative output time of a previous picture together with a temporal gap between the first picture of said second coded video sequence and the previous picture.
