1. A decoder, comprising:
- a buffer configured to incrementally transport a synchronous data stream through a path of the decoder; and
a control circuit configured to control a depth parameter associated with the buffer and to provide a substantially predictable delay of the synchronous data stream through the path of the decoder.

Abstract
A decoder includes a buffer configured to incrementally transport a synchronous data stream through a path of the decoder. A control circuit is configured to control a depth parameter associated with the buffer and to provide a substantially predictable delay of the synchronous data stream through the path of the decoder.

16. A device, comprising:
-
a decoder configured to decode synchronous data packets from a single frequency network (SFN); a first-in first-out (FIFO) circuit configured to introduce a substantially predictable delay for the synchronous data packets received from the decoder; and a control circuit configured to adjust a depth parameter that is proportional to the predictable delay, wherein the depth parameter is based on an average depth measurement of storage locations in the FIFO circuit that currently store the synchronous data packets. - View Dependent Claims (17, 18)

19. A method, comprising:
-
storing a synchronous data stream from a single frequency network into a buffer of a decoder; measuring an average depth measurement corresponding to storage locations that are filled in the buffer by the synchronous data stream, the average depth measurement being proportional to a delay in a path through the decoder; determining an error parameter that is a difference between the average depth measurement and a target parameter representing a desired delay; and reducing the error parameter in order to control the delay predictably. - View Dependent Claims (20)
