Layered coding - Wikipedia
WEBLayered coding is a type of data compression for digital video or digital audio where the result of compressing the source video data is not just one compressed data stream, as in other types of compression, but multiple streams, called layers, allowing decompression even if some layers are missing.
Scalable Video Coding (SVC) - What is it and how does it work?
WEBSVC is an advanced video coding technique that allows sending a single stream of multiple resolutions for an Selective Forwarding Unit (SFU) to decide which of the various layers to forward to users. It helps to improve data transmission efficiency across varying network conditions and devices with different capabilities.
Advanced Video Coding - Wikipedia
WEBBlock diagram of video coding layer of H.264 encoder with perceptual quality score. Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. [2]
Scalable Video Coding Standard | SpringerLink
WEBThe basic building blocks in SVC design are video coding layer (VCL) and network abstraction layer (NAL) which is similar to H.264/AVC. VCL is responsible for coding the source contents and NAL is responsible for formatting the VCL representation and provides header information appropriate for transmission through transport layer and storage media.
WEBPractical video coder. Layered coder: base layer provides basic quality, successive layers refine the quality incrementally. Fine granularity (FGS): each layer is very thin. To be useful, a scalable solution needs to be more efficient than Simulcast or Transcoding.
Video coding in WebRTC - chromium.googlesource.com
WEBIntroduction to layered video coding. Video coding is the process of encoding a stream of uncompressed video frames into a compressed bitstream, whose bitrate is lower than that of the original stream.
Scalable Video Coding - an overview | ScienceDirect Topics
WEBScalable Video Coding (SVC) refers to a method defined in Annex G of H.264 that allows the transmission of video data in a hierarchical structure. It enables the extraction of portions of the video at lower bit rates, allowing for decoding of images with different structures, picture rates, and levels of image quality.
WEBSimplified and Clean Design. No backward compatibility requirements. Compression Efficiency. Average bit rate reduction of 50% compared to existing video coding standards (MPEG-2, MPEG-4, H.263). Improved Network Friendliness. Clean and flexible interface to network protocols.
Layered screen video coding leveraging hardware video codec
WEBIn this paper, we propose a layered screen video coding scheme based on existing video codecs to leverage hardware video codec for efficient screen video compression. In this scheme, the screen video compression is performed as two-layer coding: base layer coding and enhancement layer coding.
Versatile Video Coding Based Quality Scalability With Joint Layer ...
WEBThe proposed Quality Scalable Versatile Video Coding (QS-VVC) solution is designed based on a layered coding approach with one base layer (BL) and one or more enhancement layers (EL).
