技術名稱: H.264 High Profile 編碼器矽智財

技術簡介

H.264是繼MPEG-4之後崛起的另一種新興視訊壓縮技術,其應用領域十分地多元與豐富,包括廣播、有線、衛星服務供應商、網路電視與隨選視訊、電信營運商、保全監控業與消費性電子產品如手機與相機等,都漸漸提高H.264在產品中的使用比率。 工研院資通所累積多年視訊編解碼技術能量,成功研發出具備H.264 High Profile功能的編碼器矽智財(Si-Soft Intellectual Property (IP)),並且通過H.264 reference software的解碼相容測試。本矽智財是以專用的硬體電路(fully-hardware-type)來編碼H.264影片,最高可以支援到1920x1088的解析度,畫面更新率為每秒30張畫面,完整呈現影片中的高畫質效果。

Abstract

The ITU-T H.264 standard has been developed as the next-generation compression tool for the coding of video content. Many tests have proved that H.264 has provided a factor of two in compression efficiency compared with the existing standards. Additionally, H.264 provides two conceptual layers, namely Video Coding Layer (VCL) and Network Abstraction Layer (NAL), for easily adapting the compressed content to packet-based network. With the flexibility of Soft-IP solution, ITRI can provide the industry with a high efficiency H.264 encoder core technology for digital video.

技術規格

H.264 High Profile Encoder: (1) Up to High Profile @ Level 4.0 (2) CABAC / CAVLC entropy coding (3) 4x4, 8x8, 16x16 Intra-Prediction (4) 4x4, 8x8 Transform (5) 16x16, 16x8, 8x16, 8x8, 8x4, 4x8, 4x4 MB partition for motion estimation (6) Integer, 1/2, and 1/4 pixel for motion estimation (7) B-Slice

Technical Specification

H.264 High Profile Encoder: (1) Up to High Profile @ Level 4.0 (2) CABAC / CAVLC entropy coding (3) 4x4, 8x8, 16x16 Intra-Prediction (4) 4x4, 8x8 Transform (5) 16x16, 16x8, 8x16, 8x8, 8x4, 4x8, 4x4 MB partition for motion estimation (6) Integer, 1/2, and 1/4 pixel for motion estimation (7) B-Slice

技術特色

(1) 高度硬體化編碼器: 本矽智財是以專用的硬體電路(fully-hardware-type)來編碼H.264影片,不需要高效能的CPU來分擔編碼工作,與編碼器硬體的hand shaking十分單純,讓驅動程式的撰寫較為容易。 (2) 支援高解析度影片: 最高可以支援到1920x1088的解析度,而且畫面更新率達到每秒30張循序掃描畫面(progressive)。
