Storing method and processing device thereof

摘要

A storing method comprises sequentially storing at least one first media content into at least one first fragment of a storage device, and storing corresponding at least one first media metadata into a first media metadata writing storage window; and when the storage device reaches a storage limit and at least one second media content and corresponding at least one second media metadata are intended continuously to be stored into the storage device, converting the first media metadata writing storage window into a second media metadata reserving storage window to reserve the at least one first media metadata, and sequentially overwriting at least one second fragment of the storage device with the at least one second media content and storing the corresponding at least one second media metadata into a second media metadata writing storage window.

1. A storing method, for storing data in a storage device of a video recording system, the storing method comprising:
sequentially storing at least one first media content into at least one first fragment of the storage device, and storing corresponding at least one first metadata into a first metadata writing storage window of the storage device, wherein the at least one first fragment is outside of a first metadata reserving storage window and the first metadata writing storage window of the storage device; and when the storage device reaches a storage limit and at least one second media content and corresponding at least one second metadata are intended continuously to be stored in the storage device, converting the first metadata writing storage window into a second metadata reserving storage window to reserve the at least one first metadata, and sequentially overwriting at least one second fragment of the storage device with the at least one second media content and storing the corresponding at least one second metadata into a second metadata writing storage window of the storage device, wherein the at least one second fragment is outside of the second metadata reserving storage window and the second metadata writing storage window; wherein the first metadata writing storage window follows the first metadata reserving storage window, and the second metadata writing storage window follows the second metadata reserving storage window.
