说到IP电视首先要介绍一下电视节目格式视频的基础知识,在传输中视频格式分为模拟和数字信号,模拟信号是指在时间和频率上都连续的信号称为模拟信号。表示方式是一个波形。数字信号:时间和幅度都用离散的数字表示的信号称为数字信号。表示方式是一串2进制数字。其次要说到视频编码标准,视频编码就是视频压缩(视频编码)是把数字视频流序列用更少的数据位进
When it comes to IPTV, we must first introduce the basic knowledge of TV program format video. The video format is divided into analog and digital signals in transmission. Analog signals refer to signals that are continuous in time and frequency and are called analog signals. The representation is a waveform. Digital Signals: Signals that are represented as discrete numbers in time and in amplitude are called digital signals. That way is a string of binary numbers. Second, to talk about video coding standards, video coding is video compression (video coding) is the digital video stream sequence with less data bit
