Common use of Signal Specification Clause in Contracts

Signal Specification. 6.1 The Content Transport Stream for each multiplex presented at the Signal Interface Points shall be: Television Service: o Standard Definition - 270 Mbit/s in accordance with SMPTE 259M-C o High Definition 1.485 Gbit/s in accordance with SMPTE 292M o BNC Physical Interface Radio/Audio Service: o Audio Left – Line level Audio (0dBu 1mW into 600Ω) o Audio Right - Line level Audio (0dBu 1mW into 600Ω) o Copper Wire Physical Interface Data Service (Client to define specific requirements): o EBU teletext, Digital teletext, EBU Subtitling or any other Television Service, and/or Radio/Audio Service, associated data. o Any independent teletext or data service. 6.2 System Operation Data In addition to audio, video, data and other services individual to each multiplex, each Multiplexed Transport Stream will include EIT, Electronic Programme Guide, Service Information, Conditional Access and any other operational data required for the interoperation of all Digital Terrestrial Television multiplexes Distributed and Transmitted by the Network Operator. 6.3 Multiplexed Transport Stream Transmitted by the Network Operator The Multiplex Transport Stream will be encoded and modulated as follows: Modulation 64QAM Coding Rate 2/3 Guard Interval 1/32 Number of Carriers 8k Each Multiplex Transport Stream shall have a maximum payload of 24.128 MBits/s comprising statistically multiplexed video, audio, data and other enhanced services. Each Multiplexed Transport Stream will include Electronic Programme Guide, System Information, Conditional Access or any other data required for the interoperation of all Digital Terrestrial Television multiplexes Distributed and Transmitted by the Network Operator. The Network Operator will be responsible for data integrity, service priority within the statistical multiplex and the overall management of Multiplexed Transport Stream payload. It will be a matter for the Service Provider to determine the number and quality of the television and other services to be carried in each Multiplexed Transport Stream. The Network Operator will transmit the Multiplex Transport Stream nationally using a Multi-Frequency Network (MFN).
