>> Subject: [Cloud Browser APIs] Kick-off of a new Task Force
>>  
>> Dear Web & TV Interest Group members,
>>  
>> we would like to kick-off a discussion on a potential new Task Force looking into Cloud browsers and their impact on the current specifications in the context of Web & TV.
>> We also would like to encourage those of you who might have interest in this topic to join this discussion and take part in a definition of Scenarios and Use Cases for Cloud browser APIs.
>>  
>> Outline:
>> Over the last decade Web browsers have reached desktop, mobile and also TV domains.
>> Beside connected TVs, more and more new STB deployments all over the world make use of Web browser technology as their core runtime environment for portals and applications.
>> However, there are a lot of new coming low-end devices like HDMI-Dongles and lightweight STBs that would never be able to execute the Web browser locally.
>> Indeed, also millions of legacy devices already do not have enough hardware capacity to support Web browser technologies.
>>  
>> Cloud Browser concept:
>> The Cloud browser is an enabler of a so-called Cloud-based TV User Interface (UI) that shifts a TV browser runtime environment into the Cloud.
>> Therefore, execution of the UI resides in the cloud.
>> The UI is then streamed down to the STB using a video stream.
>> This technology enables „deploy once - use everywhere“ UI concept and helps to solve device fragmentation, client browser versioning and HTML5 EME integration issues.
>> The HTML5 EME integration issue refers to a silo approach on a DRM market, where each Web browser vendor embeds its own DRM system. 
>> Therefore, Over-the-Top TV providers are forced to support Multi DRM infrastructure on their Back End.
>> Moreover, the Cloud browser UI drives deployment costs down and solves problems with low-end devices that do not have enough horse power to run a browser.
>> Additionally, the Cloud UI also tackles the legacy market.
>>  
>> Problem Statement:
>> In the last decade, after the Browser has become a runtime environment for STB middleware, a lot of work has been done by standardization bodies on the definition of device APIs.
>> These APIs were required to enable the local browser to talk to the local resources of the STBs 
>> In the mobile domain the major work has been completed by W3C, whereas in the TV domain by the HbbTV and OIPF.
>> Analog to this, new emerged Cloud browser Runtime Environments (RTEs) require the definition of APIs that would enable communication between the Cloud browser and the client.
>> This is currently a gap on the way to endow Cloud UI architectures with a rich future perspective.
>>  
>> The major Use Cases for the Cloud browser APIs are as follows (but are not limited to):
>> - Cloud application signaling for Hybrid TV environments (only the topics that do not directly deal with Hybrid TV, but rather are required browser extensions related to this topic if applicable)
>> - Tuner/ EPG (can be also extended with PVR, Volume Control, Remote Control, etc.)
>> - Multi-device
>> - Ad-insertion (tentative à IAB initiative)
>> - MSE/EME
>> (Please find detailed Use Case description in the table below)
>>  
>> Primary tasks of the Task Force:
>> - Definition of Scenarios and Use Cases 
>> - Definition of missing interfaces for Cloud RTE adaptation
>> - Interface definition
>> - Align the definition of existing gaps with the work of the TVAPI CG
>>  
>> Expected results:
>> - Cloud Browser API definition/ description
>> - Demonstrate where this TF addresses the limit of current standards 
>>  
>> Everybody is invited to the discussion and collaboration.
>>  
>> Initial interface description (to be seen as a basis for further discussions):
>>  
>> Use Case
>> Interface
>> Use Case Description
>> Cloud application signaling for Hybrid TV environments - Hybrid Broadcast Broadband TV (HbbTV) for Cloud browser RTEs
>> Cloud based HbbTV
>> In European Hybrid TV Standard HbbTV the signaling of applications is terminated by special libraries and HbbTV-enabled browser on the client..
>> This HbbTV-enabled browser is also responsible for the execution of HbbTV applications.
>> Therefore, the browser runtime environment for UI does directly affect HbbTV.
>> To enable the local HbbTV functionality in a Cloud browser RTE new interfaces HbbTV-to-cloud and cloud-to-device are required.
>>  
>> Tuner and EPG for Cloud browser RTEs
>> Cloud based Tuner/ EPG 
>> the APIs for the tuner and EPG functionality have been defined in the DVB standard.
>> All current implementation of tuner and EPG APIs on the STB market are based on the DVB specifications. 
>> Respecting the Cloud browser RTEs, the delivery concept of media and EPG data changes.
>> The corresponding Cloud Tuner and Cloud EPG APIs are required.
>>  
>> Multi-device for Cloud browser RTEs
>> Cloud based Multi-device 
>>  
>> Two major technologies that enable such a multi-device interaction are cast and companion device technologies.
>> Assuming that most of these technologies are executed locally, to enable them in Cloud browser RTEs a certain adaptation is required.
>> The Cloud based Multi-device interactions and the corresponding cloud multi-device APIs are required.
>>  
>> Ad-Insertion for Cloud Browser RTEs
>>  
>> Cloud based Ad-Insertion 
>> Both server- and client side advertisement-insertion techniques are possible and standardized already.
>> For cloud based ad-insertion server-side techniques are preferred.
>> Moreover, end users should not able to tamper with the inserted ads.
>> Furthermore, the advertisement industry should be enabled to personalize, analyze and collect statistics about played out ads. 
>> New Cloud APIs are required to enable all the different features of Ad-Insertion for Cloud Browser RTEs.
>>  
>> Media Source Extensions (MSE) / Encrypted Media Extensions (EME) for Cloud Browser RTEs
>> Cloud based MSE/EME 
>>  
>> The integration of DRM hooks into browser environments resulted in a huge disruption on how DRM works.
>> This disrupts a classical DRM approach.
>> Indeed, Over-the-Top TV Provider all over the world are already implementing MSE/EME technologies.
>> For the embedded Domain, namely Set-Top-Box and Connected TVs, no final decisions have been made. 
>> Taking into account a current MSE/EME technology ubiquity, it is very likely to happen that MSE/EME will also reach STB and Connected TV domains.
>> Owing to the local execution of current MSE/EME interfaces, they must be extended/adopted for execution within the Cloud browser.
