LEAD H.264 Professional Video Encoder

Description for LEAD H.264 Professional Video Encoder

---

• H.264 Standard and Professional Encoders include the LEAD AAC Encoder and ISO Multiplexer.
  
• H.264 Decoder includes the LEAD AAC Decoder and ISO De-multiplexer.
  
• User definable motion estimation settings controls the balance between encoder speed and quality.
  
• Multiple reference frames of any combination of past and future frames, provides precise interprediction as well as improved robustness during packet loss while streaming over the network or Internet.
  
• Unrestricted motion search uses reference frames that may be partly outside the frame improving network performance by predicting missing data.
  
• Only the difference between motion vectors is saved, increasing the compression ratio.
  
• Intraprediction may be performed either on 4x4 blocks or 16x16.
  
• Motion vector prediction is performed before the frame is prepared for compression (pre-DCT) improving prediction and compression performance.
  
• Computation is more efficient because LEAD implements the traditional Discrete Cosine Transform (DCT) as an integer transform.
  
• The LEAD H.264 Encoder makes use of the SAD HADAMARD calculation to increase the compression ratio.
  
• A context-sensitive deblocking filter smoothes out internal edges, significantly improving the visual quality of the video. The filter strength depends upon the prediction modes and relationship between the neighboring blocks.
  
• Employs Context-Adaptive Variable Length Coding (CAVLC) to encode transform coefficients.
  
• The Context-Adaptive Binary Arithmetic Coding (CABAC) method continually updates frequency statistics of the incoming data and adaptively adjusts the algorithm, improving compression performance.
  
• The LEAD H.264 Encoder provides the user with control of the number and types of frames encoded into the video stream
