In this frame for speed of encoding CAVLC was used in the base layer and CABAC was used in the three enhancement layers.
ZIMMERMANN REAL-TIME TRANSPORT PROTOCOL FOR HIERARCHICAL KEYS GENERATION OF ENCRYPTED SCALABLE VIDEO STREAMING
When the video resolution is higher, CABAC is commonly used since the compression efficiency is better than CAVLC. However, entropy decoding based on CABAC takes more time.
Entropy coding in H.264/AVC employs either CAVLC or CABAC.
A parallelization technique with integrated multi-threading for video decoding on multi-core systems
Data is compressed much more efficiently with CABAC than CAVLC; but CABAC encoding needs much more processing power to drive it.
Enhanced video security: French company ATEME has unveiled a new IP encoder that enables video security to be networked in a more efficient manner
We introduced the loop partition technology to divide the whole pipeline into four steps (ME, intracoding, CAVLC, and deblocking filter) in terms of frame.
Efficient parallel video processing techniques on GPU: from framework to implementation
Evaluation and decision on modes contribute to CAVLC, CABAC, and EXP-GOLOMB in a simplified way to address the data-handling constraints.
RiverSilica[R]: the art and science of transcoding
The entropy coding uses Exp-golomb code, context-adaptive variable-length coding (CAVLC), and the CABAC; therefore, the novel fast mode-decision method is highly effective in reducing computational processing time.
Low-complexity motion estimation for H.264/AVC through perceptual video coding
In my tests comparing similarly configured files (720p at 800Kbps video data rate) encoded with CAVLC and CABAC, the quality difference was noticeable in some hard-to-compress scenes, and I've seen some experts claim that CABAC delivers similar quality at 12%-15% lower data rates.
Producing H.264 video: what you need to know to get the most out of the web's most popular codec
Episode provides access to a good range of H.264 encoding parameters, including the Baseline, Main, and High profiles; entropy encoding (CABAC and CAVLC); and the number of B-frames and reference frames.
Telestream episode engine
However, you probably don't have the expertise to choose a codec (H.264, VP6, or VC-1), select a player (Flash, QuickTime, Windows Media, or Silverlight), or specify general encoding parameters such as resolution, data rate, or frame rate, not to mention advanced parameters such as variable bitrate encoding, B-frame interface, and CABAC versus CAVLC.
Choosing an online video platform; host your own, use a UGC site, or deploy a fee-based, SaaS approach? Here's how to decide which approach is right for you
Since I've selected the Baseline Profile, Telestream disables the "Entropy coding" mode, forcing me to use CAVLC (contextadaptive variable-length coding) with no access to CABAC (context-adaptive binary arithmetic coding).
Cracking the H.264 codec
If you experiment with lots of encoding parameters, you'd probably like to know the B-frame interval and whether CABAC or CAVLC was utilized, since both affect the horsepower required to play the file.
Under the hood: these analysis tools let you see just what those video files are made of
