H.264/MPEG-4 AVC|MVC|SVC ELEMENTARY STREAMS


Allegro DVT compliance bitstreams are designed for intensive testing of H.264/AVC|MVC|SVC decoder implementations.

Given the higher complexity of H.264/AVC compared to MPEG-2, such testing is an absolute necessity before mass deployment.

Allegro DVT provides several test suites. Each test suite targets a specific profile/level combination.

All test suites include:


Type Resolution
H.264 Baseline profile - Level 1.3 T-DMB 176x144@30fps
H.264 Baseline profile - Level 2
352x288@30fps
H.264 Baseline profile - Level 3
720x576@25fps
720x480@30fps
H.264 Baseline profile - Level 3.1
1280x720@30fps
1280x720@25fps

Stream formats:

  • Streams are delivered in Elementary Byte Steam format (Annex B).
  • They can be encapsulated in MPEG Transport (13818-1) format using Allegro DVT encapsulation software.

Methodology

Allegro DVT has developed its own H.264 encoder dedicated to generating test bitstreams. This encoder is designed for high configurability rather than maximum compression ratio. All encoding parameters (picture type, slice type, loop filter parameters, slice reordering, MMCO, macroblock type, quantization parameter, motion vector, prediction direction, intra prediction direction, constrained intra prediction, direct mode type, etc.) can be controlled at macroblock granularity.

Using this dedicated encoder, Allegro DVT has generated:

  • Syntax bitstreams for intensive testing of all compression tools.
  • Performance bitstreams for H.264/AVC performance testing against theoretical worst cases. 

All these bitstreams are the intellectual property of Allegro DVT.
