Summary

Recommendation ITU-T J.288 proposes an encapsulation scheme for type length value (TLV), a data structure specified in Recommendation ITU‑R BT.1869, for cable transmission systems designed on the basis of Recommendation ITU-T J.83.

Many of the existing digital broadcasting systems use the Motion Picture Experts Group version 2 (MPEG-2) transport stream (TS) as their input format. In contrast, variable-length packets formats such as TLV are specified for transmitting Internet protocol (IP) packets efficiently over broadcasting channels as aggregates of variable-length packets. In order to transmit TLV with the existing Recommendation ITU-T J.83 transmission system, it is necessary that variable-length TLV packets be fragmented and encapsulated into fixed-length 188-byte packets.
