PAL/NTSC H.264 Encoder

Video Menu

The Video Page is where all the
IP encoder parameters are
controlled.
The encoder supports two
encoding formats, H.264 and
MJPEG. The choice of the format
is initiated by the user when the
stream is enabled.
For example, to initiate a H.264
stream from an encoder with an IP
address of 192.168.1.195 the URL
is:
rtsp://192.168.1.195/h264
For example, to initiate an MJPEG
stream from an encoder with an IP
address of 192.168.1.195 the URL
is:
rtsp://192.168.1.195/jpeg
The Video page contains parameters for each encoder type.
The encoder has two fundamental modes of operation.
• Constant Bitrate. This is the normal mode of operation, it will output a constant bit-rate for its
compressed video stream.
• Constant Quality. In this mode the bit-rate is varied in a effort to maintain a constant quality.
The target quality is set using an arbitrary number between 1 and 50, the lower the number the
higher the quality. This is set in the quality field.
Other encoder parameters are:
H.264 resolution
The maximum resolution is 1920x1080, but users can select lower resolutions and may wish to do
so if there is restricted bandwidth available.
H.264 FPS (frames Per Second)
The maximum frame rate is 30 fps, but users may choose to select lower frame rates, thereby
reducing the bandwidth required.
