Summary:
|
This Recommendation ITU-T J.288 proposes an encapsulation scheme of TLV specified in ITU-R BT.1869 for cable transmission systems being designed on the basis of ITU-T J.83.
Many of the existing digital broadcasting systems transfer MPEG-2 TS as their input stream format. In contrast, variable-length packets formats such as TLV are specified for transmitting IP packets efficiently over broadcasting channels as aggregates of variable-length packets. In order to transmit TLV with the existing ITU-T J.83 transmission system, it is necessary that variable-length TLV packets should be fragmented and encapsulated into fixed-length 188-byte packets.
