Numbering of video objects and cells

The recording apparatus of claim 619, the system control means assign all video objects the same video object identification number.

The recording apparatus of claim 7, the system control means update the navigation data within the new cells with the assigned cell identification number.

The recording apparatus of claim 8, the system control means update the navigation data includes updating a cell elapse time within the navigation data within the new cell.

The recording apparatus of claim 9 wherein a cell, video object, a playback sequence, a cell identification number, navigation data corresponds respectively to a Cell, a Video Object (VOB), a Program Chain (PGC) ,a Cell ID number and a Navigation Pack (NV_PCK) of the DVD Read Only Video Specification.

A playing apparatus, comprising:

• means for recovering from a record carrier, a playback sequence indicating a sequence of cells that define a playable program chain of cells, the playback sequence including references to cell identification numbers that are contained in navigation data in each respective cell, the identification numbers in the sequence not being in incremental order;
• and
• means for recovering a plurality of video objects from the record carrier in accordance with the playback sequence, each cell identification number of the contiguously recorded cells being different than any other cell identification number within the same respective video object containing the cells, when the identification numbers in the playback sequence are not in incremental order or the identification numbers of sequential cells on the record carrier are not in incremental order.
