Abstract
A method of storage medium management includes providing a storage medium; storing a plurality of encoded bit streams within the storage medium; monitoring a remaining storage space available within the storage medium; and if the remaining storage space is below a threshold, transcoding a stored bit stream within the storage medium being encoded at a first bit rate to a second bit rate. When transcoding the stored bit stream to a second bit rate being lower than the first bit rate, the method of storage medium management increases the remaining space available within the storage medium.
Claims26
A method of storage medium management, the method comprising:
- providing a storage medium;
- storing a plurality of encoded bit streams within the storage medium;
- monitoring a remaining storage space available within the storage medium;
- and
- if the remaining storage space is below a threshold, transcoding a stored bit stream within the storage medium being encoded at a first bit rate to a second bit rate.
A storage system comprising:
- a storage medium;
- a codec coupled to the storage medium for storing a plurality of encoded bit streams within the storage medium;
- and
- a storage medium management module coupled to the storage medium and the codec comprising:
- a free space monitor for monitoring a remaining storage space available within the storage medium;
- and
- a controller for controlling the codec to transcode a stored bit stream within the storage medium being encoded at a first bit rate to a second bit rate if the remaining storage space is below a threshold.
A video recording system comprising:
- a storage medium;
- a codec coupled to the storage medium for encoding an incoming video signal to form a plurality of encoded video bit streams within the storage medium;
- and
- a storage medium management module coupled to the storage medium and the codec comprising:
- a free space monitor for monitoring a remaining storage space available within the storage medium;
- and
- a controller for controlling the codec to transcode a stored video bit stream within the storage medium being encoded at a first bit rate to a second bit rate if the remaining storage space is below a threshold.
