Abstract: A method and apparatus are disclosed herein for reducing at least one or both of flicker and noise in video sequences. In one embodiment, the method comprises receiving an input video and performing operations to reduce one or both of noise and flicker in the input video using spatial and temporal processing.

Abstract: An encoded video data re-compressing apparatus further compresses, for further transmission or storage, an encoded video data stream that includes quantization parameters and quantized coefficients without having to decompress the encoded video data streams and subsequently re-compress the decompressed video data. The encoded video data stream is parsed for extracting the quantization parameters and quantized coefficients from other side information. The quantized coefficients are either divided by a predetermined integer or selectively discarded to reduce the total number of bits. In the former case, the corresponding quantization parameters are multiplied by a predetermined integer. The manipulated coefficients and quantization parameters are multiplexed with the side information, such that they occupy the location of the corresponding original coefficients and quantization parameters in the video data stream.

Abstract: In a method of scaling interlaced video signals suitable for layered coding, an interpolation process is restricted within a frame where the interpolation of one field in a frame is derived from the same field and its opposite field in the same frame. The first field is converted to a first progressive image such that an interpolated line in the first field is formed by a weighted average of two or more adjacent lines in the first field plus a weighted average of two or more adjacent lines in the second field where one of these lines is at the same position as the interpolated line in the first field. Similarly, the second field is converted to a second progressive image such that an interpolated line in the second field is formed by a weighted average of two or more adjacent lines in the second field plus a weighted average of two or more adjacent lines in the first field where one of the lines in the first field is at the same position as the interpolated line in the second field.
