## Abstract

Techniques are provided for calculating a modified cumulative rendition period for a collection of temporal sequence presentation data elements, for associating the modified cumulative rendition period with the collection, and for modifying the collection based on the calculated modified cumulative rendition period in a digital rendering system for rendering the collection, when the digital rendering system includes a Variable Rate Presentation capability.

## Claims

### Claim 1

A method, performed by at least one computer processor executing computer program instructions stored on at least one non-transitory computer-readable medium, the method for use in a rendering system for rendering a collection of temporal sequence presentation data elements, the method comprising using the at least one computer processor to perform steps of:
(A) for each element in the collection of temporal sequence presentation data elements:
(1) identifying a default rendition period of the element;
(2) identifying an actual presentation rate of the element;
(3) dividing the default rendition period of the element by the actual presentation rate of the element to produce a quotient for the element;
(B) calculating a modified cumulative rendition period for the collection as a sum of the quotients produced by step (A);
(C) associating the modified cumulative rendition period with the collection; and
(D) modifying the collection of temporal sequence presentation data elements based on the calculated modified cumulative rendition period.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
(E) rendering the collection of temporal sequence presentation data elements over the calculated modified rendition period.

### Claim 3 (depends on 1)

The method of claim 1, wherein (D) comprises changing the number of elements in the collection of temporal sequence presentation data elements.

### Claim 4

A device for use in a rendering system for rendering a collection of temporal sequence presentation data elements, the device comprising at least one processor and at least one non-transitory computer-readable medium, wherein the at least one computer-readable medium comprises computer program instructions stored thereon, wherein the computer program instructions are executable by the at least one processor to perform a method comprising:
(A) for each element in the collection of the temporal sequence presentation data elements:
(1) identifying a default rendition period of the element;
(2) identifying an actual presentation rate of the element;
(3) dividing the default rendition period of the element by the actual presentation rate of the element to produce a quotient for the element;
(B) calculating a modified cumulative rendition period for the collection as a sum of the quotients produced by step (A);
(C) associating the modified cumulative rendition period with the collection; and
(D) modifying the collection of temporal sequence presentation data elements based on the calculated modified cumulative rendition period.

### Claim 5 (depends on 4)

The device of claim 4, wherein the method further comprises:
(E) rendering the collection of temporal sequence presentation data elements over the calculated modified rendition period.

### Claim 6 (depends on 4)

The device of claim 4, wherein (D) comprises changing the number of elements in the collection of temporal sequence presentation data elements.
