2021 ARS ELECTRONICA FESTIVAL Garden Taipei/ Formosa
2021 奧地利林茲電子藝術節台灣展區「台北/福爾摩沙花園:島嶼壯遊」
展區 ✨ 【行動啟程 】(Action Tour )
To cope with the impact of Covid-19, a scientific and efficient action in the digital world must be taken. The Taipei Urban Intelligence Center has developed a digital system that can quickly respond to the risk landscape, people flow, and medial resources across different parts of Taipei by integrating live streaming and data instantly. It also informs the policies of the government. The digitized action on the ground helps us build a more secured environment.
In the face of the rapid development of the digital world, people immersed in the VR environment seem to ignore the depletion of resources in our reality. As a result, we need to take real actions and devote ourselves to reuse the discarded resources to make an environment of circularity and sustainability through digital technology. MINIWIZ, a start-up company from Taiwan, committed to developing technology for recycling that turns industrial and household wastes into materials with purposes and aesthetics.
During the tour, a new performance art project is inspired by the digital cross-field cooperation for the first time. The Taipei Urban Intelligence Center will join hands with new media artist Chin-Hsiang Hu and the founder of Roboenter Ghung-I Hung, to create a new media artwork “The Weight of Data” by integrating both virtual and physical materials from different domains and sharing data resources.
Finally, it is in fact not the end for “Taiwan Grand Tour.” Instead, the “Action Tour” program unveils the journey to come, constantly connecting the digital world with our society. A link for a time-limited viewing of the details of action plans for this program as well as the joint art project will be available.
為了抵禦疫情的衝擊,我們需要在數位世界中採取科學且有效率的行動,台北大數據中心(Taipei Urban Intelligence Center)即研發了一套數位系統,透過即時的串流連結與數據整合,可以快速的反應台北各個地區的疫情風險趨勢、人流狀況與醫療資源的狀態,也可提供政府作為政策的判斷依據,數位化的實質行動,讓我們可以得到更安全的防護。
在面對數位世界的快速發展之下,沉浸於虛擬環境的我們,似乎忘卻了對於現實世界資源的消耗,因此我們需要真正的採取行動,運用數位科技的方式,重新利用我們廢棄的資源,讓環境可以永久的循環,為我們的環境盡一份心力。而小智研發(MINIWIZ)是一間來自台灣的新創公司,致力於回收材料研發科技,將工業用與家庭用的廢料,透過設計賦予它機能與美感。
而在此展區中,也首度以數位跨界的合作方式,刺激出新的行動藝術計畫,臺北市大數據中心將與新媒體藝術家胡縉祥)、樂飛特公司創辦人洪仲儀合作,進行跨域的虛實整合及數據資源共享,一同創作新媒體藝術作品《The Weight of Data》。
最終,觀者在此並不是「島嶼壯遊」的不是真正的終點,而藉由行動之旅(Action Tour)的展區開啟下一段旅程,數位世界與我們的社會持續串聯。
本展區詳細的行動計劃,與藝術聯名計劃將提供限時觀看的網址連結。

【愛曼妲專欄】5G解鎖萬物聯網 掀起大數據2.0的商務革命
葉淑明2021/07/02 10:25
眾所皆知,「物聯網」(Internet of Things)進化到「萬物聯網」(Internet of Everything)已是不可逆的科技演化。2020 年的統計資料顯示,物聯網裝置已經是全球人數的 2 倍以上,在今年(2021 年),連網裝置的總數將會達到 460 億台(日本學者曾推估 2020 年是 500 億台),成長速度非常驚人。點燃「物聯網」並添加大把柴火的其中一項關鍵技術是「5G」(第五代行動通訊系統)技術的商業化,及其基礎建設的開展普及化。
5G 與過往通訊協定的差異分別是在幾個面向:通訊距離,傳輸數據量與傳輸速度,低度延遲,可連接裝置數,消耗功率高。基於 5G 的特性,直接受惠的應用領域首先是影音串流(Video Streaming),提升了百倍的可連接裝置數,傳輸速度卻能較上一代快上百倍。 因此,5G 率先被開發使用的場景就是球場運動比賽與大型演唱會現場直播,這些場景的共通點是需要統合極大量的攝影機鏡頭與螢幕的影音數據,配合調度燈光與音響設備。簡單說,5G 技術的成熟度,直接帶動 VR/AR 相關產業,並且有利於 4K/8K 影像傳輸設備的蓬勃發展。
可預期在未來這兩年之內,物聯網市場由於 5G 技術與應用生態系的茁壯,將會開始一波爆炸成長。自去年起,在疫情肆虐之下,世界各地的網路電商產業乘風而起,電信通訊產業也積極佈建 5G。在今年,預估全球將新增 310 億台物聯網裝置,相較去年,增長數字可謂勢如破竹。如果推算物聯網市場的產值,今年會突破 5200 億美元,連網裝置的增速會超越 22%。
假設大家對這樣龐大的商機還沒有概念,參考日本學者 2020 年的研究報告,2020 年的全球物聯網市場規模約為 200 兆日圓,對比全球汽車產業的市場規模 2017 年是 220 兆日圓,2030 年全球汽車市場規模約 250 兆日圓,全球物聯網市場規模在 2030 年將成長到 400 兆日圓,大幅超越汽車產業。這亦是為何物聯網與人工智慧(AI)並列世界尖端科技的前三名,而另一個巨星當然是非「大數據(Big Data)」莫屬。
事實上,5G 技術與應用的大步發展,揭開了「大數據 2.0」(Big Data 2.0)的時代新頁。如前所述,5G 與物聯網的商業化進程密切相關,預估到了 2025 年,物聯網裝置收集儲存的數據量將累計到約為 80 ZB(Zettabytes, 皆位元組,10 的 21 次方)!雲端運算與邊緣運算的躍進(包含霧運算),再加上萬物聯網分分秒秒產生的大數據,匯聚成人工智慧新紀元的發展基礎。了解這些錯綜復雜的科技演進關聯,大家應該可以體會「腦爆」這兩個字其實是非常真切的形容,我們未來 10 年後的生活樣貌,無論是智慧工廠(製造),車聯網,智慧物流,智慧農業,能源物聯網,智慧家庭,智慧建築或智慧城市,都會讓此刻的我們無法想像,而感到瞠目結舌。
在 5G 浪潮席捲而來的時候,掌握軟硬體研發設計與工業 4.0 優勢的台灣資通訊科技廠商,勢必不可錯失良機。在通訊與感測晶片的研發設計領域,台灣科技業擁有半導體產業帶來的先天優勢,有完整的製造測試生產的上中下游供應鏈,還有獨步全球的科技研發與科技管理人才,應可參照高通(Qualcomm)在本月西班牙巴賽隆納世界通訊大會 (MWC 2021) 舉旗帶領 5G 生態系的方式,組成聯合作戰部隊,切入物聯網裝置組件與製程,建造一道堅實的護城河,甚至,充分運用 5G 生態系「以人為本」的思維,掌握物聯網裝置的小型化及大眾化趨勢,共同打造「護國群山」。時勢造英雄!

streaming data 在 YouTube Live Streaming API Overview | Google Developers 的推薦與評價
The YouTube Live Streaming API lets you create, update, and manage live events on YouTube. Using the API, you can schedule events (broadcasts) and associate them with video streams, which represent the actual broadcast content.
The Live Streaming API is actually comprised of components of the YouTube Data API and the YouTube Content ID API. The Data API enables YouTube users to manage their YouTube accounts, while the YouTube Content ID API enables interactions with YouTube's rights management system. However, all of the resources that make up the Live Streaming API are used only to create and manage live events.
This document is intended for developers who want to write applications to facilitate live broadcasting on YouTube. It explains basic concepts of YouTube and of the API itself. It also provides an overview of the different functions that the API supports.
Core conceptsbroadcasts
A broadcast represents an event that can be watched on YouTube as it happens. Broadcasts can also be recorded and saved as YouTube videos so that users can watch them after they happen. streams
A stream identifies the audio-video content that is being communicated to YouTube. Each broadcast is associated with one video stream. cuepoints
A cuepoint represents an ad break that can be inserted into a live broadcast.
API use cases
The list below suggests several ways to use the API in your application:
Schedule broadcasts and define broadcast settings. Your application could enable users to predefine broadcast settings and then select the settings to apply to a particular broadcast.
Associate video streams and broadcasts.
Enable broadcasters to define information about a broadcast and its video (using the YouTube Data API) at the same time.
Simplify transitions between broadcast states (for example, testing
or live
) and enable users to insert cuepoints.
Before you start
You need a Google Account to access the Google API Console, request an API key, and register your application.
Register your application with Google so that it can submit API requests.
After registering your application, select the YouTube Data API as one of the services that your application uses:
Go to the API Console and select the project that you just registered.
Visit the Enabled APIs page.
In the list of APIs, make sure the status is ON for the YouTube Data API v3 and, if you are a YouTube Content Partner, the YouTube Content ID API.
Familiarize yourself with the core concepts of the JavaScript Object Notation (JSON) data format. JSON is a common, language-independent data format that provides a simple text representation of arbitrary data structures. For more information, see json.org.
Authorizing API requests
As noted above, the Live Streaming API uses functionality that is technically part of either the YouTube Data API or the YouTube Content ID API. You can use the Content ID API to provide YouTube with metadata, ownership information, and policy information for your assets. (A live video broadcast is an example of an asset.) The API also lets you claim videos and set ad policies for your videos.
This section explains the authorization requirements for requests to the Content ID API, which are different from the requirements for authorizing other Live Streaming API requests.
Calling the Data API
The API request must be authorized by the Google Account that owns the broadcasting YouTube channel. Calling the Content ID API
The API request must be authorized by a Google Account that is linked to the content owner that owns the broadcasting YouTube channel.
Resources and resource types
A resource is an individual data entity with a unique identifier. The table below describes the
different types of resources that you will interact with using the
Live Streaming API. Technically, all of these resources are
actually defined as part of either the YouTube Data API
or the YouTube Content ID API. However, the
liveBroadcast
,
liveStream
, and
cuepoint
resources are
only used to create and manage live events.
Resources
liveBroadcast
Contains information about an event that you are broadcasting on YouTube. A
liveBroadcast
resource is an extension of a YouTube video resource and sets thevideo metadata that would be pertinent to a live broadcast but not to other YouTube videos.
As such, a
liveBroadcast
resource corresponds to exactly one YouTube video resource.In fact, the
liveBroadcast
resource and the
video
resource share thesame ID. And after creating the broadcast using the Live Streaming API, you can use the
YouTube Data API to provide additional metadata about the video.
liveStream
Contains information about the video stream that you are transmitting to YouTube. The stream
provides the content that will be broadcast to YouTube users. Once created, a
liveStream
resource can be bound to exactly one
liveBroadcast
resource. Similarly, theliveBroadcast
resource can only be bound to one liveStream
resource.cuepoint
Inserts a cuepoint in the broadcast video stream, which might trigger an ad break. Use the
liveBroadcasts.cuepoint
method to insert a cuepoint during a broadcast.
video
Represents a single YouTube video. As noted above, a
liveBroadcast
resource is an extension of a video
resource. You can use the YouTube Data API to update metadata about the video, such as the recording location or the regions where the broadcast will be viewable.videoAdvertisingOptions
Defines the advertising settings for a video (or broadcast). You use the YouTube Content ID API to set advertising options.
asset
Represents a piece of intellectual property, such as a movie or an episode of a show. In this case, the broadcast video is the asset. You will use the YouTube Content ID API to create and manage
asset
resources.claim
Links a video to an asset that the video matches. You create a claim, using the YouTube Content ID API, to identify yourself as the owner of the broadcast video.
policy
Defines rules that specify the circumstances under which you want your content to be viewable on YouTube or blocked from appearing on YouTube. You need to apply a policy to your broadcast video and can also specify a policy that YouTube will apply to user-uploaded videos that match your broadcast video.
Supported operations
The following table shows the different methods that the API supports:
Operations
list
Retrieves (
GET
) a list of zero or more resources.insert
Creates (
POST
) a new resource.update
Modifies (
PUT
) an existing resource to reflect data in your request.bind
Links a
liveBroadcast
resource with a liveStream
resource or removes such a link.transition
Changes the status of a
liveBroadcast
resource and initiates any processes associated with the new status. For example, when you transition a broadcast's status to testing
, YouTube starts to transmit video to that broadcast's monitor stream.delete
Removes (
DELETE
) a specific resource.The table below identifies the operations that are supported for different types of resources. Operations that insert, update, or delete resources always require user authorization. In some cases, list
methods support both authorized and unauthorized requests, where unauthorized requests only retrieve public data while authorized requests can also retrieve information that is restricted to the currently authenticated user.
Supported Operations
list
insert
update
bind
transition
cuepoint
delete
liveBroadcast
liveStream
Partial resources
The API allows, and actually requires, the retrieval of partial resources so that applications avoid transferring, parsing, and storing unneeded data. This approach also ensures that the API uses network, CPU, and memory resources more efficiently.
The part
parameter is a required parameter for any API request that retrieves or returns a YouTube Data API resource. The parameter identifies one or more top-level (non-nested) resource properties that should be included in an API response. For example, a liveStream
resource has the following parts:
snippet
cdn
status
All of these parts are objects that contain nested properties, and you can think of these objects as groups of metadata fields that the API server might (or might not) retrieve. As such, the part
parameter requires you to select the resource components that your application actually uses. This requirement serves two important purposes:
It reduces latency by preventing the API server from spending time retrieving metadata fields that your application doesn't use.
It reduces bandwidth usage by reducing (or eliminating) the amount of unnecessary data that your application might retrieve.
Over time, as resources add more parts, these benefits will only increase since your application will not be requesting newly introduced properties that it doesn't support.
Tips and best practicesClaim your contentIf you would like to show ads during your broadcast, you need to claim the broadcast video before the event begins. To claim content, you must be a YouTube Content Partner participating in the Content ID program.
The process for claiming your live broadcast video is different than the normal process for claiming a video. When claiming live video, you need to create your claim before the video actually exists. The API does support this, and the life of a broadcast document explains the YouTube Content ID API calls that enable you to create your claim.
Preview and test your contentUpon receiving your inbound video stream, YouTube can then broadcast that video on two different outbound streams:
The monitor stream enables you to preview (and test) your video broadcast. It is a private stream that is only accessible to you. You can only transition a broadcast to the testing
phase if the broadcast's monitor stream is enabled. The monitor stream does not show ad breaks.
The broadcast stream is the stream visible to your audience. You can set the broadcast's privacy status to either public
, private
, or unlisted
. (A private broadcast is only visible to users who have been explicitly invited to watch it, while an unlisted broadcast is visible to anyone with a link to view it.)
You can choose to delay the broadcast stream so that it does not run concurrently with the monitor stream. By delaying the broadcast stream, you can have more fine-grained control over the time that you insert cuepoints into the broadcast.
However, delaying the broadcast stream makes it difficult for your live presenters to interact with your viewing audience. In addition, delaying the broadcast increases the likelihood that viewers will discover key details about the event from sources other than your broadcast. For example, if you are broadcasting a sporting event on a 60-second delay, viewers might learn about critical moments in the event from other real-time news sources before actually seeing them in the broadcast.
YouTube recommends that you enable the monitor stream for your broadcast so that you can test your content. You should choose whether to also delay your broadcast based on your desire to control timing of cuepoints as opposed to your desire to interact with your audience or provide real-time coverage of an event.
Running midroll ads during a broadcast streamDuring a broadcast, you can insert a cuepoint to indicate that an ad break should start in
the broadcast as soon as possible or at a specified time. The ad break enables YouTube to run
midroll ads during the broadcast.
Ad breaks have the following characteristics:
It has a predefined length of time, which you set using the cuepoint
resource's
durationSecs
property. After the ad break concludes, viewers return to the live broadcast.
When an ad break happens, an ad only plays in the video player for viewers who are watching
the broadcast when the cuepoint is inserted. An ad does not run when viewers refresh the page
where the broadcast is playing or when visitors start watching the broadcast after the
cuepoint is inserted.
The sequence of steps below reflects the best practice for inserting an ad break during your broadcast:
Set time offsetsWhen inserting a cuepoint, you can specify that it should be inserted right away or that it
should be inserted at a specific point in the broadcast. Your options depend on whether the
broadcast stream for your video is delayed.
If your broadcast stream is not delayed, then you can insert the cuepoint immediately or use
the walltimeMs
property to have the ad break start at a particular time.
To start the ad break immediately, call the
liveBroadcasts.cuepoint
method. In theresource in the request body, set the
insertionOffsetTimeMs
property'svalue to
0
or do not specify a value for that property and do not specifya value for the
walltimeMs
property.
Important: Note that viewers do not see the resulting ad
content immediately. There may be a delay of around 30 seconds before the ad content is
visible to users. During that delay, your broadcast stream will still be visible to your
viewers, and you need to watch the broadcast stream to determine when the ad content
actually displays instead of your monitor stream.
To start the ad break at a particular time, call the liveBroadcasts.cuepoint
method and use the
walltimeMs
property to specify the desired time. The property value is an integer that represents
an epoch timestamp.
If your broadcast stream is delayed, then you can insert the cuepoint immediately as
described above, specify a clock time as described above, or you can specify a time offset to
determine when the ad break will start. The time offset specifies a point in your broadcast
when viewers should see an ad.
The offset value is measured in milliseconds from the beginning of the monitor stream for
your broadcast. Note that if your broadcast has a testing phase, then the monitor stream
starts when your broadcast transitions to the testing
status. Otherwise, your
monitor stream starts when your broadcast transitions to the live
status.
When inserting a cuepoint, set the cuepoint
resource's
insertionOffsetTimeMs
property to the desired offset.
Calculate the time offset value
To retrieve the offset value, call the YouTube Player API's getCurrentTime
function for the player that is playing the monitor stream. Use the retrieved value to insert the cuepoint in the broadcast stream at that time.
The possible values for the offset time can be calculated as the following range:
[(elapsed_time - broadcast_delay + Δ), (elapsed_time - Δ)]
The Δ
is a five-second buffer at the beginning and end of the possible time offsets when YouTube cannot precisely insert a cuepoint. For example:
A broadcast has a five-minute testing phase.
The broadcast stream is delayed 60 seconds after the monitor stream.
The broadcaster is inserting the cuepoint four minutes after the broadcast transitions to
live
status. (This is three minutes after the broadcast stream becomes visible.)
In this case, the possible range of offset times is [(485,000), (535,000)]
.
These times are specified in milliseconds, and are calculated using the following values:
elapsed_time=540000
– The monitor stream has run for nine
minutes (540 seconds, 540000 milliseconds) when the liveBroadcasts.cuepoint
method is called.
broadcast_delay=60000
– The broadcast stream is delayed by 60 seconds, or 60000 milliseconds.
Δ=5000
– The five-second buffer when the cuepoint cannot be reliably inserted.
The following guidelines explain how to resolve specific problems that may arise. For the lists
of errors that each API method might return, see YouTube Live Streaming API - Errors.
When a broadcast transitions from one status to another, it may temporarily be assigned with another status while YouTube completes the actions associated with the transition. For example, if you send a liveBroadcasts.transition
request to change a broadcast's status from ready
to testing
, YouTube will set the broadcast's status to testStarting
and then complete the actions associated with the status change. When all of those actions have been completed, YouTube will update the broadcast's status to testing
, thereby indicating that the transition is complete.
If a broadcast becomes stuck with a testStarting
or liveStarting
status, you need to call the liveBroadcasts.delete
method and delete the broadcast. Then create a new broadcast, bind it to your live stream, and continue with the testing process.
As noted in the liveBroadcasts.transition
method's documentation, you should confirm that the value of the status.streamStatus
property for the stream bound to your broadcast is active
before calling that method.
