ANSI/SCTE 21-2012 电缆数字传输数据流中垂直闪烁间隔(VBI)数据的传输标准

This document defines a standard for the carriage of Vertical Blanking Interval (VBI) services in MPEG-2 compliant bitstreams constructed in accordance with ISO/IEC 13818-2. The approach builds upon a data structure defined in ATSC A/53 Part 4 (Digital Television Standard: Part 4 - MPEG-2 Video System Characteristics), and is designed to be backwards-compatible with that method.
