1.1 Introduction and Purpose
This specification is a component of the Modular Headend Archiecture. In particular, it defines the data plane
requirements for receiving. processing. and transmitting MPEG transport streams in EQAMs, compliant with the
Video EQAM or Universal EQAM profiles described in the Architectural Overview of the Modular Headend
Architecture [SCTE 137-71]
It should be noted that this document refers to MPEG video” support as a short-hand to designate support for the delivery of IISO/IEC 1381 8-11 compliant MPEG transport streams that may carry audio material, video material, data, or a combination.
The EQAM supporting MPEG video has one or more IP network interfaces (e.g.. Gigabit Ethernet) for receipt of IPencapsulated MPEG transport stream packets that may arrive from a VOD or streaming server. The EQAM can be configured either statically (via (SCTE 137-5]) or dynamically (via ERMI-2, as defined in (SCTE 137-41) to process the incoming MPEG transport streams, generate a Multiple Program Transport Stream (MPTS), and then, from that MPTS, generate a QAM modulated RF waveform that is transmitted at a particular frequency on an RF output of the device.
1.2 Requirements and Conventions
Throughout this document, the words used to define the significance of particular requirements are capitalized.
These words are:
“MUST” This word means that the item is an absolute requirement of this specification.
“MUST NOT” This phrase means that the item is an absolute prohibition of this specification.
“SHOULD” This word means that there may exist valid reasons in particular circumstances to ignore this item, hut the full implications should he understood and the case carefully weighed before choosing a different course.
“SHOULD NOT” This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.
“MAY” This word means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item.
