Abstract (en)

[origin: WO0057647A1] Variable rate multiplexer devices have, by definition, a variable output rate for bits of information encoded therein. As a result stamp information is necessary to assure that a picture is downloaded at the current time. Unfortunately, not every picture will include time stamp information required. Therefore, some time stamp information must be inferred and applied to certain pictures. This information can be calculated by modifying a known time value with a correction value. For example, an inferred time stamp value may be calculated by adding a correction value to the time stamp value of the time stamp on the previous picture.
