System and methods for accelerated data storage and retrieval

Systems and methods for providing accelerated data storage and retrieval utilizing lossless and / or lossy data compression and decompression. A data storage accelerator includes one or a plurality of high speed data compression encoders that are configured to simultaneously or sequentially losslessly or lossy compress data at a rate equivalent to or faster than the transmission rate of an input data stream. The compressed data is subsequently stored in a target memory or other storage device whose input data storage bandwidth is lower than the original input data stream bandwidth. Similarly, a data retrieval accelerator includes one or a plurality of high speed data decompression decoders that are configured to simultaneously or sequentially losslessly or lossy decompress data at a rate equivalent to or faster than the input data stream from the target memory or storage device. The decompressed data is then output at rate data that is greater than the output rate from the target memory or data storage device. The data storage and retrieval accelerator method and system may employed: in a disk storage adapter to reduce the time required to store and retrieve data from computer to disk; in conjunction with random access memory to reduce the time required to store and retrieve data from random access memory; in a display controller to reduce the time required to send display data to the display controller or processor; and / or in an input / output controller to reduce the time required to store, retrieve, or transmit data.

Method and device for ensuring storage time for digital broadcast

When a digitized broadcast is recorded in a storage medium, a required capacity of the storage medium is firstly calculated on the basis of a bit-rate of digitized broadcast data and a recording time which is known in advance. If the remaining capacity of the storage medium is smaller than the required capacity of the storage medium, for example, a frame rate decimation and pixel reduction are performed upon a broadcast to be newly stored, a re-encoding processing is performed for the broadcast and then the resultant broadcast is stored in the storage medium. If the remaining storage capacity of the storage medium is larger than the required capacity of the storage medium and thus remains, a frame interpolation and pixel interpolation are performed for the broadcast to be stored and then a re-encoding processing is performed for the resultant broadcast in order to improve its image quality. As a result, recording of the broadcast data in the storage medium can be ensured.

Recording apparatus and reproducing apparatus

It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A tape travel speed of an archive VTR 4 is changed in response to the picture compression rate. Thus, an amount of a tape travel is optionally set depending upon a level of the picture quality. Therefore, it is possible to optionally select a tape storage space in response to the level of the picture quality.

Method for information recording and apparatus therefor

In areas on an optical disk wherein defects are detected frequently, recording is carried out while the recording density of information blocks is lowered and the amount of picture information is reduced at the same time so that digital video signals can be recorded even when defects owing to dust and flaws are present on the optical disk and so that picture losses can be prevented from occurring during reproduction.

Image recording apparatus and method, and program

The present invention relates to an image recording apparatus and method, and a program for improving usability by removing operational constraints on combinations of an aspect ratio of a recorded moving image and a horizontal resolution from users while the compliance with the DVD-Video standard is strictly maintained. When an aspect ratio is 16:9 in a state that an LP mode is selected, a horizontal×vertical resolution is set to 720×480. When the aspect ratio is 4:3 in a state that the LP mode is selected, the horizontal×vertical resolution is set to 352×480. When an HQ or SQ mode is selected, the horizontal×vertical resolution is set to 720×480 irrespective of the aspect ratio. Accordingly, the image recording apparatus can encode a moving image and record the encoded image onto a DVD 17 without violating the DVD-Video standard while allowing users to arbitrarily select a recording mode and an aspect ratio. The present invention can be applied to video cameras, video recorders, etc.
