ANSI SCTE 105-2005 pdf download Uni-Directional Receiving Device Standard for Digital Cable
14 DIGITAL AUDIO Requirement 33: The Uni-Directional Receiving Device shall not be adversely affected by any audio service type (bsmod), as defined in ATSC A/53B Standard: Digital Television Standard, Revision B. [5]
15 ANALOG TELEVISION CHANNELS Requirement 34: The Uni-Directional Receiving Device shall receive analog channels that are NTSC RF AM-VSB modulated signals in accordance with cable-system practice and applicable FCC rules.
16 CONTENT ADVISORY INFORMATION Requirement 201: Uni-Directional Receiving Devices with integrated display and without off-air tuning capability that also provide component analog or uncompressed digital output streams, shall act upon content advisory data (defined in both CEA-608-B [7] and CEA-766-A [11]) as required by FCC 47 CFR Part 15.120 [8]. Requirement 38: All Uni-Directional Receiving Devices with integrated displays and without off-air tuning capability shall have a priori knowledge of the US region RRT and support CEA-766-A [11] (i.e., the table is stored in the Uni-Directional Receiving Device). The US rating_region shall be the default rating_ region for all Uni-Directional Receiving Devices.
17 ANALOG CLOSED CAPTION Requirement 35: For analog NTSC, closed captions are carried in line 21 of the vertical blanking interval (VBI). The encoding of NTSC closed caption is based on FCC part 15.119 [8] and CEA-608-B [7]. Uni-Directional Receiving Devices with integrated displays and without off-air tuning capability shall be able to display this information.
18 DIGITAL CLOSED CAPTION Requirement 36: The Uni-Directional Receiving Device shall process and extract closed captioning information from MPEG picture level user_data() fields formatted and transported using ANSI/SCTE 21 2001 [17], when present, identified with user_data_type_code value of ‘0x03′ and cc_type values ’00’ and ’01’ and carried in the cc_data_1 and cc_data_2 fields. Requirement 36a: Uni-Directional Receiving Devices built before July 1 st , 2008, shall process and extract closed captioning information from MPEG picture level user_data() fields formatted and transported using ANSI/SCTE 20 2004 [16], when present, unless MPEG picture level user_data() fields formatted and transported using ANSI/SCTE 21 [17] is also available. UDRDs built after July 1, 2008 should not be adversely affected by the presence of SCTE 20 [16] data complying with SCTE 43, 2004 [21].
