Wipro’s readily available video components support the customer in their programs for developing systems/sub-systems based on standards like MPEG, ITU, ISO/IEC etc. Wipro provides C reference code in floating-point as well as fixed-point for various video standards. The components are tested as per the compliance standards. Wipro also has post-processing algorithms like de-blocking filters. The codecs are re-entrant and re-locatable so that they can be easily integrated into any computing platform with cross-compiling tools.

	MPEG-2 (ISO/IEC-13818-2) video decoder, Main Profile@Main Level in C++

	Typical object size : QCIF and CIF
	Picture Types: I-VOPs and P-VOPs
	AC and DC prediction
	Unrestricted motion vectors decoding
	4 Motion Vectors per macroblock
	Method 2 quantization
	Error resilience features with data partitioning and reversible variable length codes
	Robustness in the presence of errors in the bitstream. The decoder will NOT terminate but it will continue to decode from the next resync marker or start code position. The lost frames or macroblocks are concealed by substituting visual information from the previous correctly decoded frames or macroblocks
	Forward compatibility with the ITU-T H.263 recommendation [5] (meaning that the MPEG-4 decoder will be able to decode bitstreams of the H.263 coding standard at basic level)
	Bits per pixel = 8
	Compliant with ISO/IEC 14496-4. Compliance testing and verification done using both MoMuSys reference decoder and Microsoft MPEG-4 Video Decoder
	IDCT implementation compliant with the IEEE 1180 standard
	Integer Version with FAST IDCT algorithm
	Floating-point version with floating-point implementation of IDCT
	Real-time decoding (including rendering) on Pentium for 30 frames/second of CIF size
	Data memory < 40 kbytes (excluding image buffers) on 16-bit DSP for QCIF sized objects
	Performance: 40MIPS on 16-bit single MAC DSP for decoding QCIF @ 15 frames/second

	Fully compliant with upcoming ITU-T H.264/ ISO/IEC 14496 Part 10 standard requirements
	Baseline profile @ all Levels
	ANSI C compliance reference C code implementation
	Fully re-entrant to suit multi channel operation
	Error concealment as an optional component
	Can be ported to any DSP platform
	4:2:0 output format
	Interfaces: Wipro’s H.264 decoder has ready to use APIs in two variants, namely the streaming format and the file format. The H.264 video decoder is integrated with SDL display architecture. This demonstrates the decoder capabilities in the form of a visual display
