Method and apparatus for recording information in battery operated devices

In a battery operated device, a method for persistently recording information, the method comprising:

• temporarily buffering the information at a highest quality level to provide buffered high quality information;
• persistently recording the buffered high quality information at a lower quality level;
• while temporarily buffering the information at the highest quality level, receiving a device status input from a component of the battery operated device indicating a need to change recording quality level;
• and
• responsive to the input, persistently recording the buffered high quality information at a higher quality level.

A battery operated device operable to record information, comprising:

• an information sensor that provides streaming unencoded information;
• an input device that provides an input from a status-indicating component of the battery operated device indicating a need to change recording quality level;
• an encoder, operatively coupled to the information sensor and the input device, operable to encode the streaming unencoded information at a first quality level to provide first quality level encoded information and further operable, responsive to the input while encoding at the first quality level, to encode the streaming unencoded information at a second quality level to provide second quality level encoded information;
• and
• a storage device, operatively coupled to the encoder, operable to persistently store both the first quality level encoded information and the second quality level encoded information as representative of the streaming unencoded information.

In a battery operated device, a method for decoding recorded information, the recorded information comprising data supporting multiple decoded information quality levels, the method comprising:

• decoding at least a first portion of the recorded information to provide decoded information at a first quality level;
• while providing the decoded information at the first quality level, receiving an input from a status-indicating component of the battery operated device indicating a need to change decoded information quality level, wherein the status-indicating component comprises an environmental sensor configured to sense one or more environmental parameters that include temperature, vibration, and humidity;
• and
• responsive to the input, decoding at least a second portion of the recorded information to provide decoded information at a second quality level.

A battery operated device operable to decode recorded information comprising data supporting multiple decoded information quality levels, comprising:

• a source of the recorded information;
• a status-indicating component of the battery operated device, wherein the status-indicating component comprises an environmental sensor configured to sense one or more environmental parameters that include temperature, vibration, and humidity;
• and
• a decoder, operatively coupled to the source and the status-indicating component, operable to decode at least a first portion of the recorded information to provide decoded information at a first quality level and further operable, responsive to an input received from the status-indicating component while providing the decoded information at the first quality level, to decode at least a second portion of the recorded information to provide decoded information at a second quality level.

A non-transitory computer readable storage medium having stored thereon instructions that when executed by a processor of a battery operated device cause the processor to:

• persistently record the information at a first quality level;
• while persistently recording the information at the first quality level, receive a device status input from a status-indicating component of the battery operated device indicating a need to change recording quality level;
• and
• responsive to the input, persistently record the information at a second quality level.

A battery operated device operable to record information, comprising:

• means for sensing and providing streaming unencoded information;
• means for providing an input from a status-indicating component of the battery operated device indicating a need to change recording quality level;
• means for encoding the streaming unencoded information at a first quality level to provide first quality level encoded information and, responsive to the input from the input means while encoding at the first quality level, encoding the streaming unencoded information at a second quality level to provide second quality level encoded information;
• and
• means for persistently storing both the first quality level encoded information and the second quality level encoded information as representative of the streaming unencoded information.
