Abstract
A multimedia visual progress indication system that provides a cache bar that is overlaid onto the program material or displayed on a dedicated display. A cache bar indicates the length of a recording session or the length of stored program material and expands to the right when material is being recorded. Index and/or bookmark indicators are displayed next to the cache bar. A position indicator moves within the cache bar and tells the user visually where his current position is within the program material. Numeric time or counter mark of the current position is displayed in the vicinity of the cache bar. The trick play bar and its associated components are displayed for a predetermined time period.
