The new R&S®AVE264 LOW-DEFINITION VIDEO AND AUDIO ENCODER Low-Definition Video and Audio Encoder encodes video data in line with H.264, and audio data in line with HE AAC and LC AAC, in realtime.
Each instrument encodes one program with video and audio information and uses this information to generate an IP data stream. The R&S®AVP264 VIDEO AND AUDIO PLAYOUT BASE UNIT Video and Audio Playout Base Unit uses a statistical multiplex of several programs to configure and control the encoders.
The R&S®AVE264 LOW-DEFINITION VIDEO AND AUDIO ENCODER Low-Definition Video and Audio Encoder was specially designed for mobile TV (e.g. DVB-H, ATSC-M/H).
The video encoder can be operated in two different modes − constant bit rate (CBR) and variable bit rate (VBR) mode.
In the CBR mode, the encoded IP data stream is constant and independent of the current picture content.
In the VBR mode, however, the variable output data rate outputs the programs depending on the amount of picture content, which varies as a function of time.
