INTRODUCTION PURPOSE The New sat, one of the largest network provider of the U.S from the past 10 years, is going to set up 60 broadcast channels in U.K to cover the European community. According to its announcement made with reference to Tender NO-172, New sat has set up a consortium with 60 broadcasters. The current technical document is a broad outlay of requirements to set up the News collection center and its major functionalities 1.2 BACKGROUND: The proposed news collection center is planned to be established at U.K with broad casters at Scandinavia, Southern Spain, Italy, Germany and Austria. The main functions of the News collection center as follows: The news collection center at Stockbridge in the U.K will transmit and receive information from the broadcasters. The main news collection center will receive compiled news material and raw stories from Europe in the form of rich text, Audio and video from the broadcasters The News studio will transmit the compiled material to the US and European compiled material to Europe The below diagram is a schematic representation of the entire context of the proposed system from stock bridge to European and other centers.

SYSTEM SPECIFICATIONS OF THE NEWS STATION: 2.1 Transmitting Equipment: The major components in a transmitting chain consist of Transmitter, Antenna, Feeder Cable and Tower. Various combinations can, therefore, be worked out to suit individual requirements and keeping in view the availability of funds. These combinations will, however, revolve around the following parameters. Location : Stockbridge .U.K Dish : Dual Band Feed (C and KU Downlink Frequency : 3642 MHZ Polarisation : Vertical or Horizontal or Circular Symbol Rate : 19531 Msym/Sec FEC : ¾ 2.2 Receiving site equipment: The basic equipment needed by the receiving side of the TV station includes DISH, POLAR MOUNT, POSITIONER, LNB, FEED ASSEMBLY, SATELLITE CABLES, RECEIVER, and DESCRAMBLER. The diagram given below show the equipment involved in transmission of signals from geo stationary to Earth station with for TV receiver.

BLOCK DIAGREAM OF THE PROPOSED TV STUDIO LAYOUT 2.4.A MODEL NEWS ROOM INTERFACE WITH 4 CHANNELS: Source from http://www.clearcom.com 2.5.FACILITY DESIGN: The above layout is supposed to accommodate the following facility 2.5.1.Television control rooms: According to the world-class renowned technologies it is intended to develop the defined equipment requirements and developed mirror-image ergonomic layouts of the control rooms. Cooling and lighting level requirements were based on the control rooms each containing 60 monitors at 4:3 aspect ratio monitors with an expected 30 percent expansion capability. Six-inch risers separate front- deck and rear-deck operations while resting on computer flooring placed 18 inches above slab. The audio control rooms, located within each studio control room area, were designed for 5.1-channel surround sound ergonomics and acoustics for the later implementation of AC-3 audio. 2.5.2.Television master control room: The master control room’s “control point” area provides operating positions for four individuals. Master control can operate the channel 2 NTSC and channel 60 local TV stations at 720p 16:9, ultimately from a single switch. The room architecture provides stations for individuals to control multichannel, second-signal digital revenue stream opportunities. 2.5.3.Television central rack room: A 1500-square-foot room houses 60 broadcast racks. The first row bay is separated by glass and serves as the swing point of tape transition to nonlinear server technology. The Next row is supposed to accommodate large digital routing switcher and electronics that feed all news operations. Central rack room and tech core space is serviced by isolated fifth-wire grounding, generator and UPS-regulated power. 2.5.4.Television cable management: One of the most significant aspects of the TV signal design is the elaborate cable management program. All broadcast systems integration cabling is planned to be separated by its own engineering discipline (e.g. video, audio, intercom, IFB, etc.), with special attention to the separation of telephone. 2.5.5.Electricity: Power is planned to provided through dual neutral feeders from the electrical switchboard and K-rated transformers for switching power supply loads with extensive third harmonic conditions 2.5.6. Television tape archiving: A 3000-4000 square-foot vault is planned to archive over 40,000 historic tapes and provide tape storage for news and production. The strategic business plan for this space includes retrieval of tape until these programs become server-based and tape is completely phased out. The following diagram depicts the Tape archiving process into Server: TAPE ARCHIVING INTO SERVER: … High –speed bus TO Switch TAPE archive Optical Juke Box RAID Fig:5 Hardware architecture of a Video server 2.5.7.TAPE TRANSMISSION (FEED ASSEMBLY): The satellite communication of TV shows is transmitted through FEEDS. This is a cheaper and faster technology for sending Video TAPES or Stories. Feed from Production House to the NETWORK: The program is shot on film or videotape, and is then edited by a "Production House". When the program is done, it is then transmitted from U.K to European centers, where it is picked up and recorded by the network. In almost all cases, these shows are fed with NO COMMERCIALS. (2) Feed from MAIN station to Local Station This type of feed is used for Talk Shows, some Interviews, and stories prepared before. The stories that are played at the local station are sent to the main news studio through videotapes through feeds. Again, the local station will record the show for later broadcast A video server storage Hierarchy 2.5.8.MEANS OF CONVEYING COMMENTARY AND TEXT: The MIME type with RFC 1521 is proposed to be installed in the NEWS Studio for Type of message inclusions like- Rich or plain text, Gif or Jpeg Images, Basic Audio, Mpeg Video, Octet stream or Post script Application, MIME, RFC 822 message inclusion with split or total message fetch, Multi part technology for simultaneous view of different formats of RFC 822 message. 2.5.9.THE AUDIO VEDIO SYNCHRONIZATION AT TV STATION: MPEG-1:The audio encoder and Video encoder and a system Multiplexor will produce a MPEG-1 output. Audio signal MPEG-1 output Video signal Fig7: Audio Video Synchronization stream in MPEG-1 MPEG-2: For an MPEG-2 system output, Packetiser and Multiplexor are used for variable length and Fixed length packets Packetised elementary stream Video PS (Variable length Packets, common Time base) TS Audio (Fixed length Packets, no Common time base Fig8: Multiplexing of two streams in MPEG-2 3.
