Provided is a transmitter for continuously and sequentially transmitting data with a variable unit for playback. The transmitter includes an obtaining section, a buffer, a computing section and a transmitting section. The obtaining section sequentially obtains segment data of the data to be transmitted. The buffer stores an error correction code to correct an error caused in the data by transmission. The computing section computes, every time newly obtained segment data reaches a predetermined size, XOR of the error correction code already stored in the buffer and the newly obtained segment data, and then updates the error correction code with the computed XOR. The transmitting section sequentially transmits the obtained segment data, as well as reads from the buffer and transmits the updated error correction code every time the computing section computes XOR for data in a size corresponding to the unit for playback.

Transmitting data with variable unit for playback

A method for charging at least one battery, includes: determining a status of at least one parameter for the battery, where the at least one parameter comprises a closeness to a desired charge level; determining that the battery is to be charged during a peak usage time period; and determining a priority rating for the battery based upon the at least one parameter, where a battery closer to the desired charge level has a higher priority rating. The battery is then charged according to it priority rating. When batteries are to be charged for an off-peak usage time period, the charge rates of the batteries are adjusted based upon the available time for the charge. In this manner, quick recharged battery availability is provided during peak usage time periods, while battery life is prolonged during off-peak usage time periods.

A method for compensating for overcharging of at least one battery includes calculating a charge rate for the at least one battery, comparing an overcharge accumulator value for the at least one battery with a maximum time limit value, comparing the calculated charge rate with a nominal charge rate for the at least one battery, if the overcharge accumulator value is less than the maximum time limit value, incrementing the overcharge accumulator value if the calculated charge rate is higher than the nominal charge rate, if the overcharge accumulator value is less than the maximum time limit value, decrementing the overcharge accumulator value if the calculated charge rate is lower than the nominal charge rate (if the overcharge accumulator value is less than the maximum time limit value), setting the charge rate for the at least one battery to the calculated charge rate (if the overcharge accumulator value is less than the maximum time limit value), and setting the charge rate for the at least one battery to the nominal charge rate, or to a charge rate lower than the nominal charge rate, if the overcharge accumulator value equals or exceeds the maximum time limit value. In this manner, battery life may be prolonged.
