Executive Summary
This document specifies the transport of an HEVC coded video elementary stream constrained per [SCTE 215-1] intended for cable video services. There are other applications such as time-shifting (e.g., PVR/DVR service), Video-on-Demand services, and splicing (e.g., Ad-insertion) that could employ the specifications in this document. However, constraints specific to those applications are outside of the scope of this document at this time.
Scope
This document defines the transport constraints on [ITU-T Rec H.265 / ISO/IEC 23008-2] video compression (hereafter called "HEVC") for Cable Television. In particular, this document describes the transmission of a single HEVC coded video elementary stream constrained per [SCTE 215-1] over MPEG-2 transport[ISO/IEC 13818-1] for linear delivery systems supporting ad insertion services [SCTE 35]. Beyond linear delivery with DPI, signaling is provided for segmentation of contents for xDVR applications.
NOTE 1: The carriage of video in the MPEG-2 service multiplex is described in [SCTE 54].
Benefits
This specification defines transporting HEVC streams for linear broadcast delivery systems. This can interface with other systems such as digital program insertion. It can also combine different programs comprising of separate video including HDR and SDR, audio, and data packetized streams onto a single bandwidth-constrained multiplex that can be decoded back into separate programs.
Intended Audience
This specification is intended to convey information for those designing systems combining multiple video programs into a multiplex data transport.
