    摘要： Chunks (12, 14) of encoded video data of a streamed video bitstream (1) are stored and encoded video data is decoded to form decoded video data to be output for display. A selected portion (12) of the stored chunks (12, 14) or selected sub-chunks (25, 27) of the stored chunks (20, 22) for a previous, already played out part (3) of the streamed video bitstream (1) is or are discarded while keeping selected stored chunks (14) or selected sub-chunks (21, 23) stored as navigation tune-in points. The usage of selected stored chunks (14) or sub-chunks (21, 23) that are not discarded from the already played out part (3) of the streamed video bitstream (1) enables a low delay solution during video navigation when a user wants to jump to a previously played out position (5) within the streamed video bitstream (1).
