ITU-R BT.1359-1 SPANISH-1998 声音和视频广播的相对定时

When implementing the correction of relative timing difference or error of sound and vision signals, the following user requirements should be satisfied. In the case of on-line correction of the timing error of sound and vision signals, the audio quality of the sound signal when observed at the output of the sound signal timing corrector, should be maintained at the start of, during and at the end of the correction, with the quality of 4.5 or higher, when evaluated using the subjective evaluation method based on the ITU-R five-grade impairment scale and the results are presented using the diffgrade.

ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. Some 179 member countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the body which sets world telecommunications standards (Recommendations). The approval of Recommendations by the Members of ITU-T is covered by the procedure laid down in WTSC Resolution No. i (Helsinki, i 993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes the study programme for the following period. In some areas of information technology which fall within ITU-T’s purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. The text of ITU-T Recommendation X.237, Amendment 1, was approved on 5th of October 1996. The identical text is also published as ISODEC International Standard 10035-1.

ITU-T X.260-1996 信息技术.协议标识及封装框架

In a layered approach to protocol architecture, protocols have a relationship to one another such that a protocol at layer (n) uses the services of the layer below it - the (n- 1) services - which, in turn, are provided by a layer (n - 1) protocol. One of the services used by a layer (n) protocol is the encapsulation of its (n) Protocol Data Units (PDUs) in a way which is transparent to it. Such encapsulation is realized by the caniage of the (n) PDUs as user data in an (n - 1) Service Data Unit (SDU). In a limited case, the operation of a particular protocol at layer (n - 1) implies the operation, above layer (n - i), of a single layer (n) protocol or single set of related (n) / (n + 1). . . protocols. However, in a more general case, there may be more than one protocol (or set of related protocols starting) at layer (n) that can operate above layer (n - 1) in a given environment. In such cases, there is a need for explicit identification of the protocol (or set of protocols starting) at layer (n). There also may be a need to manipulate the (n - i) protocol (i.e. the encapsuhting protocol) in certain ways specific to the layer (n) protocol (i.e. the encapsulated protocol). Such manipulations form the basis of a set of procedures that must be specified for the layer (n) protocol. The above observations regarding protocol identification and encapsulation are also applicable in cases where an (n) layer is further divided into sublayers. Cases in which an (n) protocol operates for the purpose of establishing a parallel universe of protocols (regardless of the layered structure of that universe) also give rise to a need for the (n) protocol to be able to identify the protocol(s) in the parallel universe. In these cases, however, there is no encapsulatingíencapsulated relationship between the (n) protocol and the parallel universe set of protocols. The above principles lead to a need to establish a framework for protocol identification and encapsulation. These principles apply to the relationship between two protocols (recognizing that one of them may be a set of related protocols) and can be applied recursively. This Recommendation I International Standard provides a framework for explicit protocol identification and for protocol encapsulation. Implicit protocol identification (see 4.2) is beyond the scope of this Recommendation 1 International Standard.
