Xiaomi TV or Box Insufficient Memory Problem

14 Apr 2018

Xiaomi TV or box often gives out warnings about insufficient memory and causes TV or box to cease operation or having read/write errors etc. This article will explain why and how to avoid this.

What type of Memories?

ox Insufficient Memory Problem

Xiaomi TV or box has  2 type of memories.  For example,  Xiaomi TV4 has  2 GB Random Access Memory (RAM)and 8 GB storage of embedded Multi-Media Controller (eMMC) or flash memory.     The latter consists of  both a flash memory and a flash memory controller integrated in a memory chip.

Where they Use?

RAMs are mainly used for storage of Operating System (OS), current application programs and data so they can be quickly reached by the microprocessor. whereas eMMCs are used for storage of third-party apk files or its installation cache files.  It is also used to store the user data and cache and some applications that do not need instant access by the microprocessor.

Why Insufficient Memory?

When one downloads and installs too many third party apk files or the system generates too many cache files,  it will clog up the limited memories

How to Avoid?

1. Regularly use memory cleaners such as One Key Cleaner to constantly clear up the unnecessary data generated by the system while it is working; 

2. Flash and store only apks that use as little memory as possible;

3. Timely delete unnecessary apks 

What is the Official Xiaomi Cleaner?

The official cleaner is called “TV Manager”.   Unlike many other cleaners,  this cleaner has the following  functions

1. Optimise the memory space
2. Boosting Internal Memory
3. Gabbage Cleaning
4. Uninstall APKs
5. Deep cleaning
6. USB thumbdrive installation
7. Useful APKs
8. Internet Speed Test
9. Network Testing

The most commonly used functions are 1,2 and 5 for cleaning purposes

These function are explained as follows

 What are the Alternatives?

TV Manager is useful but it does not have automatic cleaning function that will clean the memory at regular intervals.   A 3rd party cleaner designed by  Shafa called “一键清理TV版”  or One Key Cleaner TV version can be viewed from here. .   It is a useful small program always running in the background.  It  will clean the memory in half hourly or other interval. 

Xiaomi TV Audio Output Connections

9 April 2018

1) The Hard Wiring Connection

2) Blue Tooth  Connection
3) More about SPDIF and  HDMI (ARC)
4) Why HDMI (ARC) Not Working

Xiaomi TV or MiTV  is originally a TV manufactured in China for Chinese market.  Plenty of users has encountered problems;  for example,  playing YouTube 4K movies or  trying to install Google Play Store.  This is because Xiaomi has omitted the supporting features not commonly found in Chinese market to cut down cost.  One of such features is the old type of analogue video and audio output ports.  

How Many Ways?

There are 2 ways to connect to MiTV's audio system

1.  Hard Wiring Method
2.  Blue Tooth  

back to top
1.  Hard Wiring Method

Xiaomi TV has only digital ports;  SPDIF is the only audio output port available.  Alternatively, one could use one of the HDMI that has Audio Return Channel (ARC) for audio connection.  This is provided the audio receiver also has an HDMI with ARC connection;  otherwise,  one would have to use an HDMI ARC adaptor which allows signal to be converted to other audio format.

a)  What is SPDIF?

SPDIF stands for Sony/Philips Digital Interface.  It is a type of digital audio connection used in consumer audio equipment.  Unlike ordinary analogue audio connection,  SPDIF  signal is transmitted digitally over either a coaxial cable or a fibre optic cable called TOSLINK connectors.   Most modern amplifiers will have SPDIF connectors;  older amplifiers only has analogue connections.

b)  What to do for Amplifiers without the correct SPDIF connection?

Xiaomi TV only has a co-axial type of SPDIF connection.   If one’s amplifier has only TOSLINK port,  one will have to buy a Co-axial RCA to Optical TOSLINK SPDIF converter as shown

  

However,  if one’s amplifier has only analogue port such as composite video/audio inputs,  one will need to buy a Digital to Analogue audio converter with RCA connectors as shown

 c)  Connecting up

In addition to the above converter,  one would need to have the right type of cables 

1.   For connection between Xiaomi TV and the converter -  A length of Co-axial digital RCA cable 

2.  For connection between the Converter and one's amplifier - either a TOSLINK cable or a set of RCA audio cable depending on one's amplifier set up

d) Any Difference between the Ordinary and Digital Co-axial Cable?

They are all having the same type of RCA connectors. 　The difference is in the quality of the cables.  The digital cable has better grade of cable and RCA connector.  However,  some claimed that there was no appreciable difference for a short length of cable connection.

e)  Connection using HDMI ARC

This audio connection is more commonly used by audiophile who often seek perfection in sound quality as it is one mean of sending true Dolby sound surround from the TV to the sound system.  For more information about how to set this up,  please refer to this article.  

back to top
2)  Blue Tooth

a)  Type of Blue Tooth　

This is the most modern way of audio connection that is being used nowadays  in almost every new sound system.   The connection is done by pairing between 2 devices for example,  the TV and the phone or the speaker system.   Up to seven or eight devices can often be paired but usually,  one 2 devices can be paired together.

MiTV has its own built-in audio bluetooth transmitter which will allow audio connection to the speaker or headphones through a bluetooth receiver such as these receivers

There are several types of blue tooth receivers available in the market.  They differ only in the way they get their power,  some has its own rechargeable battery while others has a USB charger.    Although Bluetooth standards are always backward compatible,  it is preferable to get receivers that are using the same Bluetooth standard as the TVs;  in the case of MiTV,  it is Bluetooth 4.2.

b)  Connecting up

Connecting the Bluetooth device is relatively easy.  All one has to do is to pair up the devices.  To pair up,  fire up [Setting] and select [Device and Bluetooth],  MiTV will search for available Bluetooth device in the room.  If the Bluetooth device does not show up,  try turning on the Bluetooth device as it may be switch off by default.

How Open Electricity Market Works in Singapore?

30 March 2018

 

Introduction

It was recently announced that starting from 1 April 2018,  Singapore would open up its Electricity Market also to households and small businesses that consume electricity less than SGD$400 per month.  Previously,  only those bigger consumers can join the electricity market.  

The new scheme will start from Jurong with a soft launch and gradually opens up to the rest of Singapore so that over 1.3 million households and small businesses can join the electricity market.

 

What is the Open Electricity Market?

Simply, it is just a market for buying and selling of electricity;  hopefully,  the consumers can get cheaper electricity through competitive buying and selling of electricity.

In the older days,  electricity is always generated by PUB (former SP Group) who will also deliver and sell the electricity to its consumers directly at fixed and regulated rates.  

About 20 years ago in 1998,  the Authority started the Singapore Electricity Pool (SEP) to "test" the workings of the market.  Real retail marketing started only in July 2001 when they allowed only those consumers having 2 MW or more power requirement to buy electricity from the retailers.  This market has since opened up to smaller consumers but only now,  they will open it to the 1.3 million households and small businesses in Singapore.  

How the Open Electricity Market Works?

Basically,  2 groups of people will be serving the consumers;  the retailers and SP Group.   

The retailers will buy electricity directly from the Generating Suppliers (Generators) through Singapore Electricity Pool and sell the electricity to the consumers at a rate inclusive of all fees and costs.   SP Group will continue to maintain the electricity networks and infrastructure in the background,  bringing and delivering electricity to the consumers. SP Group will also read the meters as usual.

In the open electricity market,  the consumer will have to sign a contract with the retailer of his choice.   The contract will spell out the condition of supply and also the contract period (usually 12 or 24 months) for the discounted electricity price.

 

Do I have to Join?

It is not compulsory for consumers to join the electricity market and switch from SP Group to a retailer. Consumers who prefer to stay with SP Group to buy electricity at the fixed and regulated tariff can continue to do so.  No further action will be required.  Consumers can always join or switch to a retailer at a later date.

Where can I get more details?

The exact detail of the open electricity market is outlined in this handbook

Panasonic Washing Machine Vibration and Wobbling

30 March 2018

Introduction

Just bought a Panasonic Top Load Washer NA-F75S7 for about SGD$275 with a 5% rebate from Lazada,  Singapore.  The delivery was fast,  all done within 3 days. We have used Hitachi washing machine that lasted more than 20 years;  then a Samsung washing machine that broke down after 4 years in operation.

This Panasonic is one of the cheapest and the most popular model.  We like its spin rinsing function that many other machines did not have.  It really makes washing cleaner.   But there were a few problems with this machine and one of them was that it took a longer time to wash and spin.

Why?

We discovered that the rinsing and spinning cycle repeats itself as shown in this video.  The timer jumped from 9-minute back to 14-minute during the spinning cycle.

We understand it is part of the design as it was stated clearly on the machine as shown below to carry out the "Unbalance Recovery".   But this was almost a daily affair making washing a nightmare.   We also discovered that the machine vibrated and wobbled a lot during the spinning cycle.  That could have contributed to the problem.

The Options

We have 2 options

1.      Return the washing machine as it was still within 14 days from the delivery date; 

2.      Keep the machine and try to fix the problem without voiding the guarantee.

We chose to keep the machine as we anticipated that the other machines of the same range might have similar problem. 

How to Fix?

The machine wobbled partly because the floor wasn’t flat.  Fortunately,  the machine came with a mounting adjuster but we could solve some wobbling but not the vibration problem.   We tried to redistribute the clothing nicely before washing.  This helped little to reduce the frequency repeats in the rinse and spin cycles. 

Why Vibrate?

The machine is just too light.  The casing is like made from sardine can materials.  Someone on the web forum suggested to add weight within the machine but we have chosen to add a support at the back as shown below

Whats’ Needed?

1.      One piece of 2 x 3/4” wooden strip,  about 3 feet long and cut into the following length

a.       2 pieces of 15” long to be attached to the wall and the machine

b.      2 pieces of 3.5” long as spacer

2.      1 piece of 3/16” thick  rubber sheet that can cut into 4 Nos of 3/4”x 2” rubber stud;

3.      Tools; for example, wood saw,  nails,  wood screws,   hammer etc

Step by Step

After cutting the wooden plank and rubber sheet into pieces assemble them like as shown in the following picture

 

Drill holes in the wooden plank to the exact dimension to match the holes on the washing machine.  

Fix the whole bracket to the wall as shown in the above  picture

Remove the 2 back panel screws to allow the timber frame  to be screwed onto the panel

 

The completed assembly is as shown

 

Performance

The machine performed perfectly in every washing cycle without any wobbling or any vibration.  It has never miss a "step" ever since we have fitted the timber frame..

YouTube Original or SMART YouTube for MiTV?

23 March 2018

YouTube is not a native Apps in MiTV.   This is because YouTube  belongs to Google and Chinese don’t use Google and its services in China  One can test it by resetting to factory default and the Youtube app will not be replaced.   

As a budget TV,  MiTV did not pay for the use of Google and its services but as MiTV users,  one is free to add and use Youtube.       

There are 2 versions of Youtube available:  namely,  the original YouTube for Android TV and the Smart YouTube TV

What is the basic differences?

Function	Original YouTube for Android TV	SMART YouTube TV

Tested for use	In MiTV4 but cannot sign in	In MiBox mini/2S, Amazon Fire TV, Amazon Fire TV Stick, MiTV3 and MiTV4

Which Version is Better?

If one is going for quality and better access to upgrading facilities, such as forward and backward scrolling etc,  the original version would be a better choice. But if one has to access to the YouTube video playlists and also storing some video links for viewing later,  Smart YouTube will be the one to choose.   I would recommend keeping both if there are enough memory space in MiTV.

Original YouTube has Picture to Picture Searching 

Smart YouTube TV has Sign-in Capability

Is 4K XiaoMi TV4 really a 4K Quality TV?

21 March 2018

Introduction

Many people doubted that MiTV4 was a 4K UHD TV because many could not play downloaded YouTube 4K UHD videos smoothly on the television.  This article will explain why and how to test if MiTV4 or any TV is a 4K UHD TV.

What is a 4K UHD TV?

It tells about the picture or video quality of a TV.  The ordinary analogue TV has the lowest picture quality.  The High Definition (HD) TV (the 720p or 1080p format) has higher picture quality.  4K UHD TV has the best picture quality and it has at least twice as much resolution as HD TV.   Naturally,  4K UHD TV will demand much more broadband bandwidth or hard disk storage spaces.  It will require a network speed of around 13 Mbps to play video properly.

Problem Watching 4K Movies

Watching some 4K UHD movies downloaded from Youtube can be a pain as there will be lags playing the movies;  that is if one downloaded movies of the wrong video format onto a thumb drive and watches the movie from there.   However,  one can still watch 4K UHD movies directly using YouTube without any problem as the movies have already been downgrade automatically to HD quality for viewing;  alternatively,  one can first convert the Youtube video into the correct format using a 4Kdownloader which can be downloaded from here  or here.

Why there is Video Lags?

MiTV does not have compatible hardware decoder called  VP9 to play 4K UHD  movies download from YouTube.  There are basically 3 types of 4K Video encoders/decoder for 4K UHD videos:   the libvpx (VP9), the x264 (H.264) and the x265 (HEVC).  MiTV4 and many other Chinese made TV use H.264/H.265 encoders whereas Youtube 4K UHD videos uses VP9 encoders.   

Why MiTV has No VP9?

This has something to do with cost of production.  Xiaomi is actually a TV made for Chinese market and Chinese don’t use Google;  but VP9 is a format developed by Google.   However,  VP9 is an open and royal free video encoder where users will not by charged for using such as viewing Youtube movies; but,  VP9 is a patented product and the use of which for producing devices or videos will not be free and will require licensing.

H.264/H.265 Vs VP9

These 3 formats are quite similar in terms of performance as shown in the following chart;  actually, H.265 is almost identical to VP9.  What one downloaded a 4K movie quality from Youtube is always in VP9.  If one has to upload a H.265 video to Youtube,  one would have to downgrade it first to H.264 or convert it to lower quality before uploading it to Youtube. 

How To Test 4K UHD capability?

Where to Download Demo 4K Movies?

There are free movies clips available in H.264 format for testing and most of them can be found in the Chinese apps;  for example 魔力视频TV版 (download and type 4K to search) or the various test demo from here.   

To confirm that MITV4 has 4K UHD video capability,  one could use a 4K Tester that can be downloaded from here or here.

What is in the 4K Tester?

When one starts up the tester,  one would be greeted with this page.  Press Start button to start the test

On completion of successful test,  the follow screen will appear.   The  left hand side shows the HD quality equivalent to 1008p whereas the right hand side shows the 4K UHD picture quality which is much more finer  in words and in pattern.

The following up picture tells what type of TV screen.

How Can MiTV4 play Youtube 4K Movies?

Without the VP9 decoder,  there is no way for MiTV to play Youtube 4K UHD movies.  However,  one can root MiTV4 and use a separate firmware in ROM which has in-built VP9 decoder.  The other way is to wait for Xiaomi to upgrade the firmware which may involve licensing fee.   Presently,  there is no software VP9 decoders available.
