This guide presents how to mimic the system used in professional karaoke establishments at home.  The software this system uses revolves around a Taiwanese program called JetKTV.  Much of the content from this guide was drawn from Chinese language websites discussing the usage of this program (scroll all the way down for References).    There is little literature on this subject in English and so this guide presents basically an English version of the reference sites plus a few added notes.

The program used is in Chinese, so people who are not fluent in Chinese may have a hard time navigating through the software.  Those who are brave enough to continue or have a basic knowledge of Chinese with better English fluency may find it helpful to see English instructions.  The Chinese sites on this subject are also written for older versions, and the setup procedure for those older versions are slightly different.

Proposed Setup

The proposed setup of all the hardware (TV’s, amps, computer, etc.) is in the diagram below.

The computer will play the chosen Karaoke videos and transmit the video signal to the TV (via extended display like in a dual monitor set up).  The computer’s audio will go to an amplifier or a mixer, which is then transmitted to a set of speakers.  Microphones are plugged into the amplifier/mixer is well so that the speakers can also play the sound picked up by the microphones.  Depending on the hardware, the cables could be different (some TV’s may not have HD output etc.)The  computer is the source of all the signals transmitted to the other devices and must be set up with the Karaoke software.

Setting up JetKTV2010

The PC will use the following software:

• JetKTV2010 (link)
• SongMgr (optional – not helpful on English language PC’s – more on that topic later)

It is helpful to set up the software using a dual monitor setup.  That way, it is easier to test without having to go and plug the computer to the TV each time.

Unzip the contents of the JetKTV2010 program in a folder and open JetKTV2010.exe.  The GUI buttons are for searching through the database (by looking for the artist, song name, etc.) to find the wanted song. Once a song is selected, it will be added to the list of songs to play just like the software at actual Karaoke establishments. The video will play in full screen on one monitor and the song picker GUI will say on another monitor.  To close the program, click on the top left corner of the GUI (hidden button).

Some of the software features in addition to searching and adding songs:

• Skipping songs
• Fast forwarding, pausing, etc.
• Switching from one audio channel to both audio channels (alternating between vocal on/off)

This program reads from a database that contains the song names, artists, language, etc.   Therefore, it does not come with songs.  Songs must be downloaded separately and added on.  These can come from existing DVD’s or YouTube.  The next section will explain how to populate the database.

Populating the Database

The SongMgr program mentioned above can add/remove contents from the database, but there are problems with it when using it on English language PC’s due to problems in encoding some of the Chinese characters.  Even Microsoft AppLocale fails to rectify the problems.  The solution is to use Microsoft Access to open up the database file directly and make changes.

Adding one song can seem like a lengthy process at the first try, but it will get easier as one becomes more familiar with the system.

Inserting A New Song

To insert a new song, one must navigate to the table where the songs are stored and then add an entry to it.

1. Open Song.mdbin the JetKTV program directory
2. When prompted for a password, input “tmwcmgumbonqd” without quotes
3. Navigate to the table Tbl_Song.  This is the table that records all the song entries.

Below is an explanation of each column:

• Song_ID: numerical identifier for each song (the program lists them as 5 digit numbers starting at 10000)
• Song_Title: song title
• Song_Singer: each singer has a unique number associated with them (see next section)
• Song_Singer (2nd one): the name of the artist in text
• Song_Word: number of characters in the song name
• Song_Type: a number representing a language (Mandarin,Taiwanese,Cantonese,Hakka Chinese,English,Japanese,Movies,Cartoons,Other  in that order starting from 1)
• Song_Volume: song volume, but not sure what units they are in.  Default value is 70.
• Song_Channel: the audio channel that does not have the vocal track. (1-Left, 2-Right, 3-Both)
• Song_FileName: filename of the video without the directory
• Song_Path: the directory to the file (could use absolute pathing only, but unsure of whether relative paths work)
• Song_Create: the time that the song was added in
• Song_Count: the play count of a song
• Song_Juyin: the Zhuyin characters representing the song title
• Song_Stroke: number of strokes in the first character of the song name

Some of the columns can be left out, but that means that it will not be possible to find a particular song using the omitted information.  For example, Song_Juyin can be left out for those who dont use the Zhuyin system, and that feature won’t be used for song searching anyway.

To add a song, fill out the following information at the minimum on one row:

• Song_ID (must be a unique number and should have five digits)
• Song_Title
• Song_Singer
• Song_Volume (70 is the default)
• Song_Channel
• Song_FileName
• Song_Path

For the Song_Singer information, refer to the next section.

Inserting A New Artist

Artist information is stored on a different table called Tbl_Singer

1. Open the table called Tbl_Singer
2. Fill out an entire row to add a new singer (see below for the reference for each information column)

Below is an explanation of each column:

• Singer_ID: unique identifier for each singer (this is the unique ID that is to put inserted in the Song_Singer column in Tbl_Song)
• Singer_Sex: singer gender (0-Female, 1-Male, 2-Group/Band)
• Singer_Name: artist name in text
• Singer_Juyin: the Zhuyin characters representing the artist name
• Singer_Stroke: number of strokes in the first character of the artist’s name

Testing

One a song or two has been entered into the database, one can test it by opening up the JetKTV program and trying to pick a song.  It is working when one screen shows the video playing and another screen showing the JetKTV GUI.

One can also try clicking the button labeled “導唱” to test if the audio channels are set up properly (toggling it turns on and off the vocals).

The next step would be to plug in the computer with all the television components and then trying it again.  Once everything works, the system is ready.

Ever since I got to Stuttgart I looked for a few Asian things that I always took for granted back in Vancouver. Today, I fulfilled two of these things, which was finding an Asian hairstylist to cut my hair (since I doubted that the local hairstylists in Gerlingen could do Asian haircuts) and finding authentic Chinese food.

I figured after growing my hair for 3 and a half months, the time to get a haircut came. Some time ago, someone recommended a Chinese hairstylist for me. Now I don’t speak German and I doubted that the hairstylist knew English. This meant I would probably need to speak Mandarin, although I hoped that she knew Cantonese. I grew up learning Cantonese in Canada, which means that my I lack proficiency in the language (similar to learning a language that one doesn’t receive a lot of chances to practice). If I lacked proficiency in Cantonese, surely my knowledge in Mandarin suffered even more. The only practice in Mandarin I ever got was practicing it in four classes for it almost four years ago. Everybody knows practicing a language in class is drastically different than using it in a real life setting.

On Thursday, I gave the hairstylist a call to book my appointment, and as I expected, she spoke Mandarin. Luckily I prepared myself for this. I looked up certain words that I knew I’d need to know like ‘haircut’. I drew upon what I learned almost four years ago and said that I wanted to book an appointment for a haircut. She said something back and I had no clue what she said. The only thing I could say back was, ‘sorry, my Mandarin isn’t so good’. Then she figured I knew German and started speaking that, in which case I replied ‘my German is worse’. She knew neither English nor Cantonese either.

Luckily, she started speaking slower and so I managed understand her words a lot better. I didn’t understand every single word in the sentence, but I understood enough to say something back. Less than a minute later, I successfully booked the appointment. After hanging up the phone, I realized that my heart rate rose to point that it felt like I ran a marathon. I guess I felt real nervous for my first real conversation in Mandarin.

On Saturday, I showed up at where I needed to be to get my haircut. I didn’t feel nervous speaking in Mandarin this time. In fact, I barely had to think about what I wanted to say. When people don’t have a lot of experience in a particular language, they end up thinking about how to say something. Although some questions did stump me though. I didn’t really know how to describe the haircut I wanted. I couldn’t even do that in English. So in the end, I just said to keep the hair the same style, but shorter. That’s what I wanted, and I didn’t have to describe the style.

While she cut my hair, we made random conversation and the topic of professions came up and I tried to tell her what people in my family did for a living, but I had no idea how to say that. Luckily, Google Translate helped me out with that.

I found it super ironic that my Mandarin would get better in a place like Germany, but I guess that is the difference between the Chinese community in Vancouver and Stuttgart. Most Chinese people in Stuttgart come from Mainland China, while in Vancouver, there are people from every part of China. As I left after getting my haircut, thoughts in Mandarin kept buzzing through my mind for a little while. I guess all those classes in Mandarin really paid off!

After the haircut, I went to meet up with my friend for some authentic Chinese Dim Sum. Yet again, another situation requiring me to speak Mandarin revealed itself. However, this time, the lady at the restaurant could understand Cantonese although she didn’t know how to speak it. She spoke so fast, that at the end of her sentence, I stared at her with a blank face and I had no idea what just happened. After that, she spoke a little slower and then everything became clear.

Maybe I’m overgeneralizing, but despite the fact that this definitely was an authentic Chinese Dim Sum restaurant, I felt that the quality of Dim Sum in Vancouver greatly surpassed that of this restaurant, if not Germany as a whole. It wasn’t bad, but Dim Sum in Vancouver is just better.

After lunch, we went to the Japanese Festival organized by the German-Japanese Society in Stuttgart. Here, I saw the Japanese people prepare rice cakes (Mochi). They put a large clump of rice into a wooden barrel and beat it with giant wooden mallets until the rice turned into the paste that they use for the rice cakes. They let visitors hammer the rice too, and afterward we all got to enjoy it.

Later in the evening, I went to another friend’s flat for his welcome party that was two months overdue. There I met up with the rest of my friends as well and everybody got their drink on, except for me because I only drink in moderation. The others there had a really unique way of drinking Vodka shots. They’d use these packages of powder intended for mixing with water to make juice, and they poured it in their mouth and took the Vodka shot. With the Vodka and the powder mixed together, they slosh it around before swallowing it. I tried one with the orange flavored powder, and it tasted so good, but I knew not to drink too much otherwise I’d end up puking on the floor or something.

They also introduced us to one of their drinking games. It involved pouring water into a cup floating in a bigger container of water. Each person took their turn to pour any amount of water into the cup, so long as the cup didn’t sink. The player that causes the cup to sink, must take the shot.

As the night went on, everyone got more and more intoxicated, except for me though. I just felt like going home. Unfortunately, I missed the last train back so I had to take the night bus. It took me about two hours to get home, when it would have taken me 40 minutes by train.
