Patent ID: 8416348

Claim:
A digital TV, comprising: a memory, for storing a regular program code; a signal processing module, for receiving and processing a data signal and generating an interruption signal, and a processor coupled to the memory and the signal processing module, for receiving the interruption signal and reading the regular program code from the memory, and for executing the regular program code; wherein, the memory is divided into a plurality of blocks, and the processor accesses the memory by block; each of the plurality of blocks comprises a first sub-block storing a specific program code, and when the processor receives the interruption signal, the processor reads the specific program code from the first sub-block of the currently-accessed block and executes the specific program code; wherein each of the plurality of blocks further comprises a second sub-block having a connecting program code, when the processor executes program codes of a non-currently accessed block, the processor reads connecting program code in the second sub-block to decide a next target block to access; wherein each of the plurality of blocks further comprises a third sub-block having a regular program code stored by section, the processor accesses the specific program code and the connecting program code and reads the regular program code by section to realize a function of a digital television.
