scope:

This Recommendation defines a data format and transmission protocol for the collection of service delivery metrics on customer premises equipment, such as digital cable set top boxes. Metrics are records generated by relevant service delivery events, such as a service selection event. Each metrics record includes a timestamp of the event. This technology provides a means to accurately and efficiently collect metrics for the purpose of measuring service delivery.

NOTE - The structure and content of this Recommendation have been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T Recommendations has not been applied.

Introduction and Purpose

The purpose of this Recommendation is to specify metrics collection and transmission mechanisms and interfaces on receiver platforms. The data formats and transmission protocols may also be adopted by proprietary systems.

For the purposes of this Recommendation, the term "metrics" refers to specific data, defined herein, that is generated by a receiver and transmitted to a cable headend.

Metrics, as defined in this Recommendation, are intended to complement other measurement systems that may be employed by cable operators.
