 ETHERNET STREAMING PROTOCOL 

 
OVERVIEW 
 
The DVR streams audio/video data on TCP port 1234.  This port is used for 
audio/video only.  No control information is sent via this port. 
 
All control will be performed using standard commands via the Telnet interface on 
TCP port 23. 
 
The DVR allows multiple clients to stream audio/video if desired. This is limited to 
a maximum of 8 external connections (RS-232, Telnet, FTP, or Streaming). 
 
Video data is sent every frame.  Audio data is buffered and sent five times a 
second, or every 200 milliseconds. 
 
BANDWIDTH THROTTLING 
 
If Ethernet bandwidth (or client resources) become congested, the DVR will 
throttle bandwidth by dropping video frames.  No audio will be dropped.  Dropped 
video frames are marked in the data stream by sending zero length video frames 
so that the client can keep track of dropped frames to ensure audio/video 
synchronization. 
 
DATA STREAM FORMAT 
 
The data stream consists of audio/video blocks.  Each block begins with an 8 byte 
header which contains an audio/video stream identifier and a block length.  This 
header is the standard AVI data chunk header and is defined as follows: 
 
chunkId: 32-bit audio/video stream identifier 
chunkSize: 32-bit integer indicating number of data bytes following this header 
 
The stream identifiers are (in little endian format): 
 
Video Stream #1:  0x63643030  ("00dc") 
Audio Stream #1:  0x62773130  ("01wb") 
 
Video Stream #2:  0x63643230  ("02dc") 
Audio Stream #2:  0x62773330  ("03wb") 
 
Video Stream #3:  0x63643430  ("04dc") 
Audio Stream #3:  0x62773530  ("05wb") 
 
Video Stream #4:  0x63643630  ("06dc") 
Audio Stream #4:  0x62773730  ("07wb") 
 
If any video frames are dropped by the DVR, they are indicated by receiving a 
video chunk with a size of 0 bytes.
