22% of Digital Video Consumption Is On Mobile

Data from NPD group

Screen size, resolution and display clarity are important factors

influencing the mobile user experience

By 2020, 60% Mobile Data Traffic Will Be Video

* tablets are associated with a much higher share of online video traffic than smartphones

● Total mobile video traffic over the next 6 years will

be more than 22 times that of the last 6

Why is instant gratification on mobile important?

• People != Patient

• Affects the impression of your brand

• 10s delay in loading video, 40% of your users drop off

• Lost opportunities to show a video Ad due to poor or no

connectivity

• HD quality and instant play lead to higher user

engagement with your app

Akamai Study: 10 seconds delay 40% users drop

Grow revenue opportunities with fast, personalized

web experiences and manage complexity from peak

demand, mobile devices and data collection.

PCD Lego Blocks

• Prediction: Analytics from usage data, social media, preferences provide details on what content to

curate

• Congestion Detection: Network preferences (Wi-Fi, cellular or both) and network availability identify the

timing of the downloads

• Download Manager: Background download mechanisms efficiently download content on the device

SDK Control and Data Flow

PCD Architecture

1) Service Layer

2) Data Layer

3) Storage Layer

3 Layers of PCD SDKSync Layer

• Sync layer communicates with the VOC server to send registration message, establishes the login with the server

• Sync layer enforces multiple device side policies ensuring the optimal and preferred usage patterns for the client in terms of

battery life, data usage, and storage usage. (For example, prepositioning of content could be restricted to be only during

charging, or only over Wi-Fi network, only over cellular during certain time windows during the day, or at certain network

congestion levels or only so much data per day etc.).

• Sync layer is notified of availability of new download manifest on server via push notifications (Google Cloud Messaging in

case of Android, and Apple Push Notifications in case of iOS), based on which it pre-positions content on device.

Data Layer• This layer is responsible for storing the meta-data for prepositioned content on the device. On iOS platform, meta-data is

stored as part of the Core Data infrastructure provided by the platform, and on Android side, the meta-data is stored in a local

SQLite database.

• Data Layer is accessible for both UI and Sync Layers, through clearly defined API interfaces, specific to each platform (for

eg:- Content Provider interfaces in Android)

Storage Layer• Once content is prepositioned on device, it is stored in files (hls, dash, mp4), locally on device internal storage.

• Local storage the application can use to preposition content on device is configurable.

• There are eviction mechanisms that run to ensure storage usage does not exceed the allocated storage levels. Eviction

Algorithm runs when storage level is at more than 80% of the allocated space. Eviction algorithm removes expired content,

followed by oldest watched content to bring down the cache usage to 50% of the allocated storage.

PCD API Quick Reference

• createVocService

• register / unregister

• performCacheFill / clearCache

• likeFeed / dislikeFeed

• subscribeCategory / unSubscribeCategory

• subscribeTopic / unSubscribeTopic

• downloadFeeds(String[] feedIds);

• updateFeedConsumptionStats / updateFeedAdConsumptionStats

• getPolicyStatus / getCongestionStatus
