MPEG transport stream

Multiple MPEG programs are combined then sent to a transmitting antenna. The receiver parses and decodes one of the streams.

Standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data.

Historically, many different definitions of IPTV have appeared, including elementary streams over IP networks, MPEG transport streams over IP networks and a number of proprietary systems.

ATSC standards

American set of standards for digital television transmission over terrestrial, cable and satellite networks.

Digital terrestrial television broadcasting systems. Countries using ATSC are shown in orange.

For transport, ATSC uses the MPEG systems specification, known as an MPEG transport stream, to encapsulate data, subject to certain constraints.

MPEG-2

Not to be confused with MPEG-1 Audio Layer II (MP2).

MPEG-2 is used in Digital Video Broadcast and DVDs. The MPEG transport stream, TS, and MPEG program stream, PS, are container formats.

Part 1: Systems – describes synchronization and multiplexing of video and audio. (It is also known as ITU-T Rec. H.222.0. ) See MPEG transport stream and MPEG program stream.

Network packet

Formatted unit of data carried by a packet-switched network.

Network Packet

A typical method of transmitting elementary stream data from a video or audio encoder is to first create PES packets from the elementary stream data and then to encapsulate these PES packets inside an MPEG transport stream (TS) packets or an MPEG program stream (PS).

Electronic program guide

Electronic programming guides (EPGs) and interactive programming guides (IPGs) are menu-based systems that provide users of television, radio and other media applications with continuously updated menus that display scheduling information for current and upcoming broadcast programming (most commonly, TV listings).

Listings data for IPGs integrated into digital terrestrial television and radio receivers of the present day is typically sent within each station's MPEG transport stream, or alongside it in a special data stream.

Program and System Information Protocol

Multiple MPEG programs are combined then sent to a transmitting antenna. An ATSC receiver then decodes the TS and displays it.

The Program and System Information Protocol (PSIP) is the MPEG (a video and audio industry group) and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended for the ATSC digital television system for carrying metadata about each channel in the broadcast MPEG transport stream of a television station and for publishing information about television programs so that viewers can select what to watch by title and description.

Digital Video Broadcasting

Set of international open standards for digital television.

All data is transmitted in MPEG transport streams with some additional constraints (DVB-MPEG).

MPEG program stream

Container format for multiplexing digital audio, video and more.

Multiple low data rate signals are multiplexed over a single high data rate link, then demultiplexed at the other end

It is designed for reasonably reliable media such as disks, in contrast to MPEG transport stream which is for data transmission in which loss of data is likely.

Digital video

Electronic representation of moving visual images in the form of encoded digital data.

Container format

File format that allows multiple data streams to be embedded into a single file, usually along with metadata for identifying and further detailing those streams.

Computer science container formats examples

MPEG-2 transport stream (a.k.a. MPEG-TS) (standard container for digital broadcasting and for transportation over unreliable media; used also on Blu-ray Disc video; typically contains multiple video and audio streams, and an electronic program guide)
