Definitions
- the invention relates to methods for encoding a digital video image and can be used for efficient encoding of video data in video file formats and streaming and broadcast video formats.
- a digital image such as a video image, a television image, a still image or an image generated by a VCR or computer, consists of pixels arranged in horizontal and vertical lines.
- the number of pixels in one image frame is usually tens of thousands. Each pixel typically contains luminance and color information.
- a digital image without encoding contains a large amount of information.
- JPEG, MPEG, and H.263 standards In order to reduce the amount of information transmitted, a number of different encoding methods have been developed, such as JPEG, MPEG, and H.263 standards.
- frames of the original video sequence are divided into rectangular regions or blocks that encode in internal mode or in intermediate mode. Blocks are independently encoded using some form of transform coding, for example, such as DCT (Discrete Cosine Transformation).
- DCT Discrete Cosine Transformation
- the technical result of the claimed invention is aimed at improving the quality of the digital video image obtained by encoding the original digital video image.
- the specified technical result is achieved by encoding the original digital video image, while the original digital video image is taken in any format and with any resolution that exceeds the required, for example:
- the original digital video image is divided into a plurality of video frames, wherein each video frame of the plurality of video frames is divided into a plurality of blocks of pixels.
- At least one encoded video image is formed from the sequence of video frames as follows:
- each subsequent frame is added to the encoded video if it is completely different from the previous video frame;
- the multiplicity of aspect ratios of the video frame in the encoded digital video image can be arbitrary while observing the square shape of the pixel, however, to achieve the optimal quality of the digital video image, the aspect ratio of the video frame in the encoded digital video image is recommended to be a multiple of the aspect ratio of the display device;
- the coefficient of multiplicity can be either an integer or a fractional number.
- bitrate Bit rate x File duration
- the resulting encoded video image is stored on at least one media server.
- All steps of the method disclosed in this invention can be directly implemented using computer technology or in the form of a software module (software), which is executed by the processor.
- the software module can be stored in random access memory (RAM), flash memory, read-only memory (ROM), erasable ROM, electrically erasable ROM, register, hard disk, removable disks, compact discs ROM (CD-ROM) or any other known information carriers.
- the storage medium may be integrated into the processor.
- the processor and the storage medium may be located in a specialized integrated circuit.
- a specialized integrated circuit may reside in a user terminal.
- the processor and the storage medium may reside as discrete components in a user terminal.
- the digital video encoding method disclosed in the present invention consists of several steps or actions implementing the described method. The order of steps or actions may be changed without departing from the scope of the present invention.
