摘要： In general, the disclosure describes various techniques for providing edge-directed scaling filters that may be used to scale image data. An example device includes a storage medium configured to store a first lookup table and a second lookup table, and one or more processors configured to obtain one or more gradient values that each indicates a gradient between values of at least two pixels in a source image. The one or more processors are also configured to generate one or more inverse gradient values from a first lookup table based on the gradient values, and to generate one or more edge-directed scaling filter coefficients from a second lookup table based on the inverse gradient values. The one or more processors may be further configured to generate an edge-directed filter based on the coefficients, and to apply the filter to the at least two pixels to generate an interpolated pixel.

摘要： This disclosure describes selection of reference video units to be used for interpolation or extrapolation of a video unit, such as a video frame. A decoder may apply a quality-focused mode to select a reference frame based on quality criteria. The quality criteria may indicate a level of quality likely to be produced by a reference frame. If no reference frames satisfy the quality criteria, interpolation or extrapolation may be disabled. Display of an interpolated or extrapolated frame may be selectively enabled based on a quality analysis. A decoder may apply a resource-focused frame interpolation mode to enable or disable frame interpolation or extrapolation for some frames based on power and quality considerations. In one mode, frame interpolation may be disabled to conserve power when reference frames are not likely to produce satisfactory quality. In another mode, the threshold may be adjustable as a function of power saving requirements.

The techniques may utilize a temporal approach in implementing the ABL scaling to adjust the backlight level of a display for a current video frame in a sequence of video frames presented on the display. The techniques may include receiving an initial backlight level adjustment for the current video frame and determining whether to adjust the backlight level adjustment for the current video frame based on a historical trend. The techniques may also determine the historical trend of backlight level adjustments between the current video frame and one or more preceding video frames in the sequence.

摘要： A video decoder performs a sequential error handling process to detect and conceal errors within a corrupted data segment of video data units. The decoder sequentially decodes a current data unit. Upon detecting an error, the decoder sets an error flag and resynchronizes decoding at the start of the next unit. If the error flag is set, the video decoder identifies the end of the corrupted data segment based on the start of the later unit. The decoder conceals data between the start of the current unit and the end of the corrupted data segment. If the error flag is not set, the decoder may decode the remainder of the current unit and proceed to decode the next available unit without performing error handling and concealment for the current unit. The decoder also may address reference unit mismatches caused by lost video data units.
摘要翻译：视频解码器执行顺序错误处理过程以检测和隐藏视频数据单元的损坏的数据段内的错误。解码器对当前数据单元进行顺序解码。在检测到错误时，解码器设置错误标志并在下一个单元的开始重新同步解码。如果错误标志被设置，则视频解码器基于稍后单元的开始来识别损坏的数据段的结束。解码器隐藏当前单元的开始和损坏的数据段的结束之间的数据。如果错误标志未设置，则解码器可以对当前单元的剩余部分进行解码，并且继续对下一个可用单元进行解码，而不对当前单元执行错误处理和隐藏。解码器还可以解决由丢失的视频数据单元引起的参考单元不匹配。

摘要： Channel map information includes program map table information in packetized program information used in video processing and storage medium formats. In a digital video system for decoding an MPEG compatible datastream containing MPEG compatible program map table information, channel map information is identified and assembled. The channel map information identifies individual packetized datastreams that constitute a broadcast program. The channel map information associates a broadcast channel with packet identifiers used to identify individual packetized datastreams that constitute a program transmitted in the broadcast channel. The channel map information replicates information conveyed in the MPEG compatible program map table information.

摘要： Described are a system and method to determine the initial luma and chroma phase such that the resulting image after chroma upsampling and scaling has zero phase difference between the luma and chroma components. Particularly, the described method may include receiving a subsampled input image having luma and chroma values. The method may then perform a phase computation of the input image to determine scaling parameters such that phase differences between all color components of an output image are zero. The method may then include performing a combined upscaling and upsampling process on the input image using the scaling parameters to generate an upscaled image with no phase difference from the subsampled image.
