1. A memory initialization sequence for a memory in a DTV set-top box of the type having a front panel function that includes a program-controlled microprocessor and a DTV application function for processing at least part of a audio/visual signal wherein the memory initialization sequence commences upon power-up, comprising the steps of: searching for the presence of a selected file indicative of initialization of the memory; starting a DTV application function if the selected file is present; and effecting a memory initialization routine if the selected file is not present, the memory initialization routine starting a timeout task/counter associated with the front panel function and having a timeout period of M time units and starting a recurring re-set/refresh task associated with the DTV application function having a reset/refresh time period N time units to successively reset/refresh the timeout task/counter, where N is less than M time units, and, concurrent with the operation of said timing task/counter, formatting the memory and creating a file indicative of initialization of the memory, and, after creation of the selected file, terminating the reset/refresh task to allow the timeout task/counter to timeout, and, upon timeout of the timeout task/counter, re-seting the DTV application and thereafter taking the DTV application out of re-set.

2. A method of memory initialization sequence in a memory in a DTV set-top box, the set-top box having a front panel function that includes a program-controlled microprocessor and a DTV application function for processing at least part of a audio/visual signal wherein the memory initialization sequence commences upon power-up, comprising the steps of:

first placing the DTV application function out of reset;

a second step of starting boot-up sequence of DTV application function;

a third step of searching for a file indicating that the memory is at least one of a protected and a formatted file;

if the memory is not the at least one protected and formatted file, a fourth step of starting a timeout task/counter associated with the front panel function and having a timeout period of M time units and starting a recurring re-set/refresh task associated with the DTV application function having a reset/refresh time period N time units to successively reset/refresh the timeout task/counter, where N is less than M time units;

concurrent with the operation of said timing task/counter, formatting the memory and creating a file indicative of initialization of the memory; and

a fifth step of terminating the reset/refresh task to allow the timeout task/counter to timeout, and, upon timeout of the timeout task/counter, re-setting the DTV application and thereafter taking the DTV application out of re-set.

3. The method of claim 2, wherein M time units is set to 4 seconds.

4. The method of claim 2, wherein reset/refresh time period N is less than or equal to 2 seconds.

5. The method of claim 2, wherein the memory is a flash memory.
