Overhead is affected by the total number of packets and by the size of stream packet headers. In high bitrate encodings, the content payload is usually large enough to make the overhead data relatively insignificant, but in low bitrate encodings, the inefficiency of the overhead can significantly affect the resulting file size if the container ...
If the DID is equal to 128 (0x80) or greater, then the packet is a Type 1 packet, and the DID is sufficient to identify the packet type, and the following word is a Data Block Number. If the DID is less than 128, it is a Type 2 packet , and the following words is the Secondary Data Identifier; the DID and SDID together identify the packet type.
The common architecture specification defines a format of nested protocol data units (PDUs), rather similar to TLV encoding, which are used in the main protocols. It then defines how a minimal Root Layer Protocol is used to splice the higher level protocols into a lower level transport and defines such a Root Layer Protocol using the PDU format for use on UDP/IP.

In the CP, DCF is used. In the CFP, the AP sends Contention-Free-Poll (CF-Poll) packets to each station, one at a time, to give them the right to send a packet. The AP is the coordinator. Although this allows for a better management of QoS, PCF does not define classes of traffic as is common with other QoS systems (e.g. 802.1p and DiffServ).
Each table structure is broken into sections, although some tables like a PMT cannot have more than one section. Each section can span multiple transport stream packets. On the other hand, although this is uncommon, a transport stream packet or set of packets under the same PID can contain multiple sections belonging to different tables. [1]
The maximum bit rate value in the sequence header of the MPEG-2 video stream is 19.4 Mbit/s for broadcast television, and 38.8 Mbit/s for the "high data rate" mode (e.g., cable television). The actual MPEG-2 video bit rate will be lower, since the MPEG-2 video stream must fit inside a transport stream.
Listener (stream destination) and Talker (stream source) primitives are utilized. Listeners indicate what streams are to be received, and Talkers announce the streams that can be supplied by a bridged entity. Network resources are allocated and configured in both the end nodes of the data stream and the transit nodes along the data streams' path.
