Transport Stream is a term that is commonly used in the world of digital video broadcasting. It refers to a method of transmitting digital video and audio data over a network. The Transport Stream is a container format that is used to encapsulate the data that is being transmitted. This article will provide a glossary of terms related to Transport Stream.

MPEG: MPEG stands for Moving Picture Experts Group. It is a group of experts that develops standards for digital video and audio compression. The MPEG standards are used in many different applications, including Transport Stream.

Packet: A packet is a unit of data that is transmitted over a network. In Transport Stream, packets are used to encapsulate the video and audio data. Each packet contains a header and a payload.

Header: The header is a part of the packet that contains information about the packet. It includes information such as the packet identifier, the length of the packet, and the type of data that is contained in the packet.

Payload: The payload is the actual data that is being transmitted. In Transport Stream, the payload contains the video and audio data.

PID: PID stands for Packet Identifier. It is a unique identifier that is assigned to each packet in Transport Stream. The PID is used to identify the type of data that is contained in the packet.

PCR: PCR stands for Program Clock Reference. It is a timing reference that is used to synchronize the audio and video data in Transport Stream. The PCR is included in the header of each packet.

PTS: PTS stands for Presentation Time Stamp. It is a timing reference that is used to synchronize the presentation of the audio and video data. The PTS is included in the header of each packet.

ES: ES stands for Elementary Stream. It is a type of data that is contained in Transport Stream. The ES can be either video or audio data.

PES: PES stands for Packetized Elementary Stream. It is a type of data that is used to encapsulate the ES. The PES includes a header and a payload.

PCR Accuracy: PCR Accuracy is a measure of how accurately the PCR is being transmitted. The PCR Accuracy is important because it affects the synchronization of the audio and video data.

Transport Stream is a complex topic that requires a good understanding of the terminology that is used. This glossary of terms should help to clarify some of the key concepts that are involved in Transport Stream. By understanding these terms, you will be better equipped to work with Transport Stream and to troubleshoot any issues that may arise.
