Introduction

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

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

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

Create an 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"
    }
  ]
}

"port": 8110,
"starting": false,
