Preparation:
01- Linux CentOS-59
02- Tomcat 6
03- DNS server
04- NTP server [date 2010.April.04 / time 12:00

[140409]
Tomcat location: http://10.11.0.1
Tomcat manager login: admin / admin

Local Path: /DH_INSTALL
Server Function: Deploy EPG metadata to STB.

Digisoft DHWeb server package:
Version 1.2 for STB version PROD_2.9.29.11.zip
Version 1.3 for STB version PROD_2.9.31.5.zip

Insert DHWeb into Apache Tomcat
01- Access Tomcat via http://10.11.0.1

02- Login Tomcat manager page: admin / admin

Required field:

• Context Path (required): digihost
• WAR file to Deploy --> Select WAR file to upload

Note:
WAR filename's naming rule: "digihost.war"
直接 upload Digisoft 給的 Server 檔名為 "DHWeb-1.2-SNAPSHOP.war", 可以 upload 成功, 但是 STB 的 EPG 出不來.

05- DHWeb located on "/DH_INSTALL/apache-tomcat-6.0.29/webapps" after deploy
Upload 成功後, Server 會產生一目錄在 /DH_INSTALL/appche-tomcat-6.0.29/webapps
目錄名稱會與 Upload 的檔名同名.

Note-1: DHWeb 內的檔案修改後


Support IP Streaming
Service: DHWeb / Digihost
File: WEB-INP
Path: /DH_INSTALL/apache-tomcat-6.0.29/webapps/digihost/

只留一條 multicast 的 IP 位置給 STB 使用.
STB 只會讀取 Server 送出的第一條位置/IP.

Test Pattern
1-
別使用有支援多個 programs 的 TS file, 這樣有可能造成 STB 播放的影片與音來自不同的頻道.
就像是影像來自 Channel 1, 但聲音來至 Channel 2 一樣.
2-
別使用也只有支援一個 program 的 TS file, 這樣有可能造成 STB 只有影像, 但沒有聲音.
3-
Pattern 只能使用像 MPEG 檔, 影音同時輸出.

Note-1: WEB-INP 修改給 IP streaming 使用後, 會造成 STB 無法接收來至於 DVB-C pattern generator 的影片.
