摘要： In one embodiment, a method receives a plurality of sample values. The method then determines a filter to determine an up-sampled value for a first layer for a video, wherein the filter has a set of coefficient values of [-1, 3, -8, 60, 13, -4, 1, 0] or [0, 1, -4, 13, 60, -8, 3, -1] assigned to the filter. The up-sampled value is determined by applying the set of coefficient values of [-1, 3, -8, 60, 13, -4, 1, 0] or [0, 1, -4, 13, 60, -8, 3, -1] to the plurality of sample values. The method then outputs the up-sampled value for use in coding a second layer of a higher resolution than the first layer. The up-sampled values may be for the 3/16 and -3/16 phase offsets.

摘要： A sampling filter process is provided for scalable video coding. The process provides for resampling using video data obtained from an encoder or decoder process of a base layer (BL) in a multi-layer system using adaptive phase shifting to improve quality in Scalable High efficiency Video Coding (SHVC). In order to compensate for phase offsets introduced by downsampling an appropriate phase offset adjustment is made for upsampling in SHVC with an appropriate offset included for proper luma/chroma color space positions. In one approach the luma/chroma phase offset is specified and a filter is selected to apply the appropriate phase change. In another approach, an adaptive filter is signaled with its phase offset adjusted to account for the luma/chroma offset.

摘要： A sampling filter process is provided for scalable video coding. The process provides for resampling using video data obtained from an encoder or decoder process of a base layer (BL) in a multi-layer system using adaptive phase shifting to improve quality. Examples of a multilayer encoder or decoder process are MPEG-4 Advanced Video Coding (AVC) and High Efficiency Video Coding (HEVC). The re-sampled BL data can be used in encoding or decoding of a corresponding video data of higher layers in a scalable video coding system. For example, the re-sampled or upsampled data can be used as a basis for prediction of the higher resolution video data.

摘要： A method for determining a resampling filter for resampling a video signal used in scalable video coding includes estimating a set of row filters based on a video signal. The video signal has a base resolution that is resampled to provide an output signal that enables more efficient coding of the video signal with an enhanced resolution higher than a base resolution. The set of row filters is applied to the video signal to generate a first output signal having rows that are interpolated to the enhanced resolution. A set of column filters is estimated based on the first output signal for resampling the columns in the video signal. The set of column filters is applied to the first output signal to generate a second output signal having columns as well as rows that are interpolated to the enhanced resolution.

摘要： Upsampling filters for use in scalable video coding may be selected from a set of filters each with a different phase. In order to accommodate a phase offset introduced from downsampling required to maintain proper luma/chroma color space positions after upsampling, an offset parameter may be used in computing the filter index. Moreover, a different offset may be used for each filter index. These offsets in effect provide a re-mapping of the filter indices. By remapping the filter indices in this manner the performance of the upsampling process can be improved and errors introduced by rounding or which are caused by the finite precision of the process used to compute the filter indices can be taken into account.
摘要翻译：用于可缩放视频编码的上采样滤波器可以从具有不同相位的一组滤波器中选择。为了适应在上采样之后维持适当亮度/色度颜色空间位置所需的下采样引入的相位偏移，可以使用偏移参数来计算滤波器索引。此外，可以对每个滤波器索引使用不同的偏移。这些偏移实际上提供了过滤器索引的重新映射。通过以这种方式重新映射滤波器索引，可以提高上采样处理的性能，并且可以考虑由用于计算滤波器索引的过程的有限精度引起的舍入引起的错误或引起的误差。
