Introduction

The Zapper channel lineup can be managed through the EELM Server. It allows the Zapper channel lineup to be managed programmatically without inputting the channel manually. In addition, it allows the operator to perform channel change programmatically. For more details on the EELM Server, please refer to this article.

Note: This will not work for 3rd party apps

Enabling the EELM feature

To enable the EELM feature, please add the following INI parameter

• eelm.enable=1  

NB: The device needs to be rebooted after the configuration change

Using the EELM API for the Zapper Lineup 

This section shows some useful examples of editing the channel through the EELM Server. In my example, I am using an H200 STB with IP 10.0.7.82

Create a channel "101"

curl -X 'POST' \
'http://10.0.7.82:8090/api/v2/zapper/channels' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "addr": "233.22.133.1",
  "desc": "UDP 1",
  "drm_session_type": "persistent",
  "encrypting_server": "string",
  "encryption_request_header": {},
  "encryption_type": "string",
  "igmpv3_addr_list": [
    "198.51.100.42"
  ],
  "igmpv3_mode": "asm",
  "name": "101",
  "port": 8110,
  "starting": false,
  "type": "udp"
}'

hint: set the "starting" to specify the 1st channel being played after boot

Get the channel "101" info

curl -X'GET' 'http://10.0.7.82:8090/api/v2/zapper/channels/101' -H 'accept: application/json'

Sample output

{
  "addr": "233.22.133.1",
  "desc": "UDP 1",
  "drm_session_type": "persistent",
  "encrypting_server": "string",
  "encryption_request_header": {},
  "encryption_type": "string",
  "igmpv3_addr_list": [
    "198.51.100.42"
  ],
  "igmpv3_mode": "asm",
  "name": "101",
  "port": 8110,
  "starting": false,
  "type": "udp"
}

Return complete channel lineup

curl -X 'GET' 'http://10.0.7.82:8090/api/v2/zapper/channels' -H 'accept: application/json'

Sample output

{
  "channels": [
    {
      "addr": "233.1.1.20",
      "desc": "UDP 20",
      "drm_session_type": "persistent",
      "encrypting_server": "string",
      "encryption_request_header": {},
      "encryption_type": "string",
      "igmpv3_addr_list": [
        "198.51.100.42"
      ],
      "igmpv3_mode": "asm",
      "name": "20",
      "port": 8110,
      "starting": false,
      "type": "udp"
   },
   {
     "addr": "233.22.133.1",
     "desc": "UDP 1",
     "drm_session_type": "persistent",
     "encrypting_server": "string",
     "encryption_request_header": {},
     "encryption_type": "string",
     "igmpv3_addr_list": [
       "198.51.100.42"
     ],
     "igmpv3_mode": "asm",
     "name": "101",
     "port": 8110,
     "starting": true,
     "type": "udp"
    }
  ]
}

Create or change the channel info of channel "101"

curl -X 'PUT' \
'http://10.0.7.82:8090/api/v2/zapper/channels/101' \
-H 'accept: */*' \
-H 'Content-Type: application/json' \
-d '{
"addr": "233.22.133.1",

],
"igmpv3_mode": "asm",
"name": "101",
"port": 8110,
"starting": false,
"type": "udp"
}'

Tune in to channel 101

curl -X 'POST' 'http://10.0.7.82:8090/api/v2/zapper/changeChannel' -H 'accept: */*' -H 'Content-Type: application/json' -d '{ "name": "101" }'
