Abstract: A recording system and process minimizes the storage capacity for recording multi-channel data into the memory space normally allocated to a single channel for a predetermined time period without compressing the data. In order to enable the data to be correlated with either real or relative time, the data is recorded along with its channel number and stored sequentially in an electronic memory in predetermined time increments. Additionally, the channel activity is monitored and stored. By recording the channel number with the data and identifying the periods of channel activity, the recorded data can be correlated with the time during which it was recorded. The recording apparatus in accordance with the present invention is particularly well suited for minimizing memory requirements for recording multi-channel sequential data, such as in certain voice communications, as well as simplex and half duplex communications even in situations where there is some overlap in channel activity without the use of data compression.

Abstract translation: 记录系统和处理将存储容量最小化，以将多通道数据记录到通常分配给单个通道的存储空间中达预定时间段，而不压缩数据。 为了使数据能够与实时或相对时间相关联，数据与其通道号一起被记录，并以预定的时间增量顺序地存储在电子存储器中。 另外，监视和存储通道活动。 通过记录具有数据的通道号和识别通道活动的周期，记录的数据可以与其记录的时间相关联。 根据本发明的记录装置特别适用于最小化用于记录多信道顺序数据的存储器要求，例如在某些语音通信中，以及即使在通道中存在一些重叠的情况下的单工和半双工通信 活动没有使用数据压缩。
