Meet the needs of China's digital television development, in particular in order to solve the problem of the difference channel reception system, the channel reception mode and other functions Block separated from the digital television receiving equipment out, in favor of digital television receivers industrial equipment to meet the needs of the market and technical exchanges, Especially the development of this part of GB/T 26275 of. This portion of the SJ/T 11337-2006 "digital television receiving equipment Conditional Access Interface Specification Part 1-2. DTV-CI test specification "complementary use. Digital television receiving equipment machine channel separation DTV-CSI Interface specification - Part 2. Test Specification

1 Scope

GB/T 26275.2-2010 is the Chinese national standard on dtv-csi interface specification for channel separation of digital television receiver part 2: test specification, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 January 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2011. Classification: ICS 33.160.25, CCS M74. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 26275 specifies the digital television receiving equipment machine channel separation DTV-CSI interface test conditions, and test items Test Methods. This section applies to machine and channel separation card from a combination of "single separation" mode or "double separation" of a digital television receiver.
