Abstract:
There are provided video encoders and corresponding methods for performing fast mode decision of B-frames. A video encoder for encoding video data for a B slice that is divisible into macroblocks includes an encoder (OO) for performing mode selection when encoding a current macroblock in the B slice by counting a number of neighboring macroblocks in the B slice coded in a DIRECT mode, and only checking one of the DIRECT MODE or a 16×16 mode for the current macroblock when the number of neighboring macroblocks coded in the DIRECT mode exceeds a predetermined threshold.
