| JCTVC-O0165 Real time SHVC software decoding with multi-threaded parallel processing [S. Gudumasu, Y. He, Y. Ye, Y. He (InterDigital)]
Reviewed Tues 29th (GJS).
This contribution describes a parallel decoding framework for SHVC. Various optimization technologies were reportedly implemented on the basis of SHM-2.0 software to achieve real time decoding speed. Multi-threading and SIMD optimizations were reportedly applied to accelerate the decoding process.
Experiments on a desktop with Intel i7 processor 2600 running at 3.4 GHz reportedly show that the parallel SHVC software decoder is able to decode 1080p spatial 2x scalability up to 60 fps (frames per second) and 1080p spatial 1.5x scalability up to 50 fps. The bitstreams were reportedly generated with SHVC common test conditions.
One thread was used for entropy decoding and multiple threads were used for decompression based on "CTB groups" and an "application thread manager" was used for control.
SIMD was used for MC, IQ, IT, and reconstruction.
The contributor suggested that this confirms that the reference index approach provides a suitable design for real-time decoding.
