1013 Optimizing Video Delivery With The Open Caching Network

Delivering a great video experience requires content to be served as close to the end-user as possible. In this whitepaper, we illustrate how network operators can implement Open Caching nodes at the edge of their network, while adhering to specifications created by the Open Caching Working Group of the Streaming Video Alliance. These nodes can mitigate delivery latency and provide an improved viewer experience when hosted by the ISP and connected to the CDN/Content Provider nodes outside of the operator network, to create an Open Caching Network.

1023 Metadata Landscape

The evolution of content distribution models over the past decades has introduced a tremendous amount of flexibility for content processing and delivery. The availability of metadata, which provides information related to descriptive, business, and technical aspects of content, is needed to take advantage of advanced content streaming approaches. Commonly used metadata approaches primarily serve static distribution models. Additionally, there are a lack of solutions available that provide a consistent, user-friendly, and efficient approach to managing metadata. This document provides a starting point for understanding metadata usage and challenges and looks at organizations that have developed metadata-related standards.

1024 5G and the Edge Cloud for Streaming Video

As mobile networks evolved, became faster and offered more and more bandwidth, consumer habits also changed. Users began to adopt data-hungry activities like streaming video, streaming music, and cloud gaming. As the networks have continued to improve, so too has our expectations of the amount and quality of content delivered to our devices negating many of the benefits offered by the latest network and radio infrastructure.

The popularity of OTT services such as Netflix and YouTube are burgeoning and the demand for video content on mobile devices is rising exponentially placing massive demands on current 4G networks. Increased demand is just one aspect though. New formats like 360 degree video and XR in conjunction with higher definition including 4k and 8k are becoming common for videos viewed on connected devices, particularly those streaming content to big screen TV’s or head mounted VR units and as video quality rises, so does the need for faster connections to enjoy seamless streaming.

The ability to stream high quality video HD content requires download of less than 5 Mbps while an ultra-HD 4k video requires around 15 Mbps depending on the codec and compression. Both are easily supportable with the constraints of the current 4G specification however when combined with massive catalogs and insatiable demand, shared bandwidth on a radio network quickly becomes exhausted.

Even if the ability to stream at a high bandwidth is available, its not much use if the 4G radio network is not accessible. While operators continue to build out their 4G infrastructure we still experience far from ubiquitous coverage. When users lose their 4G connection the service is normally bumped down to 3G network which is typically 5 times slower making it impossible to initiate or continue to stream content. Clearly 4G cannot support the quality of service that most major content brands expect need to present to their consumers or the low latencies that XR and Cloud Gaming applications require.

5G has the potential to deliver a broad, disruptive user experience throughout the Media and Entertainment vertical, and will extend the metaphor of very simple content delivery to mobile devices that is prevalent in the market today, to an immersive, interactive and tactile shared experience for video entertainment, cloud gaming and extended reality (XR). With exceptional QoE combined with new business models that will include hyper-targeted advertising and enhanced QoE, 5G has the potential not only to bring content closer to the consumer, but also bring consumers closer together within the content ecosystem.

2004 Open Cache Logging Requirements Specification

This document specifies requirements for Open Caching System (OCS) for Logging data to help track data acquisition and delivery of it to the end user. The information logging is critical for the Open Caching Nodes as well as the upstream CDN and the Content Provider (CP). Logging information helps OCS track key performance metrics such as, data acquisition, delivery success and failures, measuring of effective throughput, cache hits and for troubleshooting fault and performance degradation. The logging data provided to the CDN by the OCS is also used by CDNs for auditing, billing and SLA purposes. The information logging will also be used by Open Caching Nodes (making up an OCS) for ensuring its compliance of SLAs with CDNs and measuring and assuring
Quality of Experience (QoE) for an end user.

2053 Ad Creative Signaling in DASH and HLS

The two most common streaming formats for Adaptive Bitrate Streaming – Dynamic Adaptive Streaming over HTTP (DASH) and HTTP Live Streaming (HLS) – provide mechanisms for ads to be inserted into manifest files. However, there’s often a challenge to properly identify the unique ad asset(s) that are embedded in a manifest. This hampers efforts to ensure delivery and monitoring accuracy.

This document proposes a clear and interoperable signaling mechanism for the signaling of creative assets in DASH and HLS. It enables, for example, unique ad asset identifiers such as those from Ad-ID.org and/or unique in-house ad asset IDs to be captured in original or stitched manifest files.

5002 Key Network Delivery Metrics

This document describes key network delivery metrics for streaming Internet video. The Streaming Video Alliance Quality of Experience (QoE) working group (WG) developed these metrics as a common language to describe effectiveness of network delivery. Although many more metrics could have been documented, these particular metrics represent the most common and important metrics according to the QoE WG group membership. It is expected that these metrics can be used across the streaming video ecosystem to provide guidance that can lead to enhancement of QoE.

5010 Geo-Data for IPv6

There are many different approaches to associating attributes to an IP address and many different attributes that can apply. There are also several different approaches to delivering that data. This document will focus on attributes that fall into three categories: Identity, Service, and Location. Identity can include a user’s name, the upstream service provider, an enterprise network, university, or department. Services can include attributes such as a W-Fi network, cable, wireless, infrastructure, and enterprise. Finally, location attributes can identify city, state, zip codes, country, region, or geocodes. A collection of attributes would form objects with their associated values, and these objects can be related to an individual IP address or a range of addresses to create an IP addressing object. These IP address objects can also be tied to an IP address object in a parent child relationship to provide as much detail as desired by the source. This document provides a JSON object model and schema to represent how those attributes can be tied to an IP address in a common format for controlling the access to streaming video using geo-location data for IPv4 and IPv6 addressing.

Note: access controls, privacy, and the management of privileged information (PII) will not be defined here and will be left to other efforts.
