MPEG2 - an overview | ScienceDirect Topics
网页Mpeg-1 and Mpeg-2. MPEG-1 and MPEG-2 are standards for video and audio compression and transmission developed by the Moving Pictures Experts Group. MPEG-1 (sometimes simply referred to as MPG files) was used on video CDs (VCDs) in the 1990s. VCDs were popular in Asia but did not see widespread availability in the United States.

A blind MPEG-2 video watermarking robust to camcorder recording
网页2010年4月1日 · Abstract. Based on the observation that low-frequency DCT coefficients of an image are less affected by geometric processings, we propose a new blind MPEG-2 video watermarking algorithm robust to camcorder recording. The mean of the low-frequency DCT coefficients of the video is temporally modulated according to the information bits.
Transport Stream - an overview | ScienceDirect Topics
网页ATM: Asynchronous transfer mode, a protocol for high performance networking. A transport stream packet (TSP) comprises 188 bytes – a 4-byte header (whose first byte has the value 47 h), including a 13-bit packet identifier (PID), and 184 bytes of payload. Packet size was designed with ATM in mind: One TS packet fits into four ATM cells (48 ...
