Title:
METHOD AND APPARATUS FOR FAST MODE DECISION OF B-FRAMES IN A VIDEO ENCODER
Document Type and Number:
WIPO Patent Application WO2006052577
Kind Code:
A3
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 16x16 mode for the current macroblock when the number of neighboring macroblocks coded in the DIRECT mode exceeds a predetermined threshold.
