Editorial notes

~~Should be put in programming part~~: If you want to work on MHP, you might be interested in getting openmhp api at [http]

OpenMHP. You need to register first. And get openmhp104_bin.zip, and its source file. Also note that the JMF part is left out. You need to download it separately at http://java.sun.com/products/java-media/jmf/2.1.1/download.html. Lastly, you also need to have Java 1.4. JRE installed in your programming machine. Without it, they wouldn't work. Java 1.4, JRE can be downloaded at: http://java.sun.com/j2se/1.4.2/download.html. For more information, please refer to http://www.openmhp.org/D_download.php .

or download OpenMHP.zip (19.03 MB) .

http://www.alitronika.com/home.htm is offering modulator equipment, which is an alternative tool for testing data broadcasting transport streams. The problem is that it only offers for DVB variable-specifications such as DVB-S DVB-C DVB-T DVB-H etc. These would not be useful in our situation except one. The excpetional one is "DVB-S" which is used in the satellite industry in Korea. (see also, http://forum.java.sun.com/thread.jspa?forumID=36&threadID=589662 threads)

Also, if you have a modulator equipment, you might be interested in getting the software player such as [http]

mimundotv and tv card. This will get the transport stream right into the tv card. Then, diplayed onto your monitor screen via software. This eliminates STB and TV set purchase. But, notes that you need to buy tv-card and software; but, they are cheaper than TV set alone. Maybe?
