Methods and device for data alignment with time domain boundary

An apparatus for processing multimedia data, wherein the apparatus is implemented at least partially in hardware or a processor, the apparatus comprising:

• a content classifier configured to obtain a content information of the multimedia data, wherein the content information includes content classifications based on a Human Visual System for a plurality of macroblocks in the multimedia data, each content classification for a macroblock determined by a particular combination of a texture value and a motion value from among a plurality of combinations of texture and motion values, the texture value associated with spatial complexity of the macroblock, and the motion value associated with temporal complexity of the macroblock, wherein the texture value and the motion value are based on a human visual sensitivity metric;
• and an encoder configured to encode each of the macroblocks in the multimedia data as intra-coded macroblocks or inter-coded macroblocks based on the content information associated with each macroblock to increase the error resilience of the encoded multimedia data, wherein encoding each macroblock includes selecting an error resilience scheme based on the content classification, wherein the error resilience scheme is selected from the group consisting of at least one item selected from among aligning a data boundary with a frame boundary in time domain, predictive hierarchy, and adaptive intra refresh.
