The invention provides a non-aqueous secondary battery having positive and negative electrodes and non-aqueous electrolyte containing lithium salt which has an energy capacity of 30 Wh or more, a volume energy density of 180 Wh/l or higher, which battery has a flat shape and is superior in heat radiation characteristic, used safely and particularly preferably used for a energy storage system. The invention also provides a control method of the secondary battery.

Non-aqueous secondary battery and its control method

A video signal producing system includes an imaging device for obtaining progressive imaging signals having various frame rates, a recording device for recording an output signal of the imaging device and a reproduction device for reproducing a recording signal obtained from the recording device. The imaging device includes a frame rate converting portion for converting the imaging signals to an output having a predetermined frame rate and the reproduction device changes a reproduction speed in response to each of the various frame rates so as to generate an output having a substantial number of frames such that the substantial number of the frames assumes a predetermined value.

A number of outer parities to be added to an audio data is changed responsive to a ratio of frame frequencies of a video signal (e.g. 24 Hz or 30 Hz) before the data is recorded. Comparing with a first format, a recording bit rate is increased in a second format. Audio 4 channels (audio sectors ) are additionally recorded maintaining a video data format (video sectors ) of the first format and an audio data format (audio sectors ) of the first format.

Record and playback device

A video signal recording apparatus including a switching device for receiving a digital progressive scan TV signal having a frame cycle which is &frac12; of the frame cycle of an interlaced scan TV signal and switching the progressive scan TV signal frame by frame alternately; a coding device for performing high-rate coding of data corresponding to one frame of the progressive scan TV signal to the same code amount as obtained by high-rate coding of data corresponding to one frame including two successive fields of an interlaced scan standard-definition TV signal; and a recording device for recording the data processed with the high-rate coding in the same number of tracks as the data corresponding to one frame of the interlaced scan standard-definition TV signal.

High efficiency coding device and high efficiency coding method for image data

The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.

A digested video signal producing device for producing digested video signals from the original video signals recorded the video tape includes a Read/Write head for reading the recorded video video sinal, a tape winding unit for positioning the video tape to predetermined recording positions with respect to the Read/Write head, a reproduction circuit for reproducing the original video signal, a decimating circuit for producing a digested signal by sampling the reproduced original video signal every other predetermined even number of fields, a storage circuit for storing thus obtained digested video signals, and a control unit for control overall operation of the device. When producing the digested video signal, the video tape is positioned to the first recording area where the original video signals are recorded. Sampled digested video signals are repeatedly stored in the storage circuit until the storage circuit is full. Then the video tape is rewound to a second recording area for recording thus obtained digested video signals.

An apparatus records and reproduces high efficiency coded video signal to and from a recording medium and includes an important data generating circuit for generating at least an important data from an input video signal, a data arranging circuit for arranging the important data so as to be recorded at predetermined positions, and a recording and reproduction control circuit for controlling recording and reproducing operations. The input video signal is separated into information common to each large block and information native to small blocks of the each large block. A coding mode of each of the small blocks thus separated is judged. The input video signal is divided into a plurality of packets, data for generating a common information from the input video signal is decoded, the common information thus generated is stored at a predetermined position of a packet, and each packet is sequentially recorded on a recording medium. Data for generating a common information from a predetermined position of each packet is read out when reproducing a recorded signal, the common information is generated from read-out data, and plural small blocks are collected using the common information thereby to compose a large block, so that high speed reproduction can be obtained when an intra-/inter-picture coded signal is recorded.

In an encoding side, an estimate of input data is generated. An estimation error which is equal to a difference between the estimate and the input data is calculated. The estimation error is classified, thereby generating a category index indicative of a category corresponding to the estimation error. The input data is divided by a divisor, and a remainder of a result of the dividing is generated. The divisor is equal to a given value which is greater than a difference between an upper limit value and a lower limit value defining a range of the category. The category index and the remainder are encoded into corresponding codes which are outputted. In a decoding side, input data is decoded into a category index and a remainder. An estimate is generated from previous output data. A divisor is generated in accordance with the category index. An offset is generated in accordance with the divisor and the estimate. The offset is equal to the divisor multiplied by an integer. The offset and the remainder are added, and thereby new output data is generated in accordance with the offset and the remainder. In the presence of a control signal, the estimate is generated by a prediction process which differs front a prediction process in an encoding side. In the presence of the control signal, the offset is generated so as to increase a correlation between output data and the estimate.
