1. SCOPE OF DOCUMENT

The standards defined in this document apply to all high definition content delivery via tape, file or incoming live feed for Astro broadcast. The document is also intended for those who work at producing HD content to be broadcast on Astro platform. The purpose is to serve as an aid in selecting proper parameters and as a guide for adapting the best production techniques in creating HD content that meets Astro technical standards and specification for an enhanced HD viewing experience. The standards described in this document are also intended to serve as a reference to ASTRO personnel who review and approve the technical quality of HD content.

2. TERMINOLOGY

HD:

This term is used for native high definition productions, live or on tape, carrying high definition signals.

SD:

This term is used for native standard definition productions, live or on tape, carrying standard definition signals. It encompasses analog and digital signals and formats.

Anamorphic 16:9 SD:

Component digital video format having a 16:9 aspect ratio, made of 720 x 576 pixels that can be recorded and processed as a regular 4:3 SD signal. Sometimes referred to as full height anamorphic 16:9 SD.

HDV:

Consumer format mainly developed by Sony that allows the recording of 1440 x 1080 pixel images (at 30i) and 2 audio tracks, compressed at 25 Mbps, long GOP, on DV tapes.

Lo/Ro: (Left Only / Right Only) Conventional stereo signal.

Lt/Rt:

(Left Total / Right Total) Matrix-encoded stereo signal in either Dolby Surround or Dolby Pro Logic II.

Dolby E: Dolby coding system optimized for the distribution of multi-channel audio through

two-channel audio within professional production environments. Even after multiple encoding cycles, there is no significant degradation in audio quality.

Dolby Digital: (AC3)

Dolby coding technology that can deliver 1- to 5.1-channel audio programmes in a variety of configurations, intended for distribution to the consumer through SD/HD digital television broadcast. Unlike Dolby E, this technology is not suitable for multiple coding cycles.

LPCM

Linear pulse-code modulation (LPCM) is a particular method of pulse-code modulation which represents an audio waveform as a sequence of amplitude values recorded at a sequence of times. LPCM is PCM with linear quantization

Figure 1



3. QUALITY ASSESSMENT STANDARD

Because HDTV is by nature and by definition an electronic medium of superior quality to conventional or standard definition television (SDTV), Astro considers that subjective quality requirements must be accordingly and significantly more stringent. The image quality of HD programme provided on tape shall be evaluated according to the five-point scale suggested in the International Telecommunication Union standard.

Rating Quality Impairments Remark

5 Excellent Imperceptible Acceptable

4 Good Perceptible but not annoying Acceptable

3 Fair Slightly annoying Acceptable

2 Poor Annoying Not Acceptable

1 Bad Very annoying Not Acceptable

Figure 2

Programme should meet the criteria for a 5 rating. Exceptionally, on programme portions including, for example, archival material, the minimum acceptable quality shall be a 3 rating



4. VIDEO SPECIFICATIONS

Video Footage should be acquired using formats acceptable to Astro broadcast standards for transmission.

4.1. Incoming HD video signal source format

Input Format Frame Rate (fps) Scan Lines

1920 x 1080/50i 25 Interlace 1125 Figure 3

Video programme material shall be produced using industry standard and accepted norms. Astro requires that its production partners use only selected codec and media types when working in non-linear editing systems. Systems that use uncompressed HDSDI are acceptable, as are systems use the HDCAM formats. Systems that exclusively use HDV codec or are incapable of using HD-resolution media are not acceptable for online output. If there are questions about the qualifications of a particular editing system or type of media, please contact Astros Content Compliance Department for clarification.

4.1.1. Vertical blanking should equal lines 1-20 and lines 561-563 of the first field and lines 564-583

and lines 1124-1125 in the second field.

4.1.2. Horizontal blanking should be between 280 clock periods and a maximum of 292 clock periods, creating a blanking width of between 3.775 microseconds and 3.935 microseconds when a clock period is equal to 13.48 nanoseconds.

4.1.3. Video white levels should not exceed 700mV for component signals, and programme black

levels should not extend below 0 Vdc. Neither the programme luminance whites nor blacks should be clipped excessively. For colour difference signals R-Y and B-Y, levels shall not exceed 700 mV or fall below 0 mV when set at a 350 mV offset.

4.1.4. Programme Text Title Safe Area for 1080 line signals, the safe title area is the central 80% of

the picture, an area of 1536 by 864 pixels beginning 192 pixels from the left edge and 108 pixels from the top of the image and ending 1728 pixels from the left edge and 972 pixels from the top of the image.

Figure 3a

4.1.5. Video programme material which produced using DSLR Cameras is not accepted. This has

determined that, usages of DSLR camera in productions are having issue with poor quality and resolution (compression artefacts). (based on the facts stated below)



DSLR capture and record in H.264 codec, this codec is not supported and therefore not recommended for pre and post production.

DSLR record in Progressive instead of interlace scanning (24P, 25P & 30P).

Color sampling 4:2:0.

DSLR use still camera lens.

When recording for long periods, especially in warmer climates, increased video noise may occur due to CMOS overheating.

Moir patterns will appear on video

Flickering will appear on alternating darkening and brightening of the visuals. .

Quality degration during transcode from H.264 to other editing codec (H.264 is high compression codec).

4.1.6. TVC content delivery:



5. AUDIO SPECIFICATIONS

Audio programme material shall be produced using current industry standards and accepted norms. The audio portion of the master and source audio and videotapes must be produced so that no noise, static, dropouts or extraneous distortion is recorded in the audio. Programme audio must reflect reference tone level. Audio levels must be consistent throughout the programme. 5.1. Stereo (LPCM)

5.1.1. Channel allocations

Channel 1 Full mix stereo left

Channel 2 Full mix stereo right

Channel 3 Dolby E

Channel 4 Dolby E Figure 4

5.1.2. Phasing

Stereo audio must be fully mono compatible, i.e. the audio channels must be in the proper phase. NOTE: Full Mono compatibility means that when the left and right stereo channels are actively combined to mono there is no discernible change in audio level or fidelity. Full mix and M&E audio tracks should be phase coherent (synchronized) and level matched to prevent difficulty editing between these tracks, as necessary.

5.1.3. Sound to Video Synchronization (Lip-synchronization) The relative timing of sound to video should not exhibit any perceptible error. Sound should not lead or lag the vision by more than 10ms. This synchronization must be achieved at the last point at which the programme supplier, or their facility provider, has control of the signal.

5.1.4. Headroom Transmission limiters clip at +8 dB. For broadcast stereo tracks, transient audio peaks must not exceed +8 dB above reference tone when measured on an audio meter using the "True-peak" ballistic set (0 ms rise, 200 ms fall). When mastering to a digital format and/or using an Absolute Scale or Peak meter, where "0" is at the top of the scale and reference tone is at -20 dBFS, broadcast stereo tracks should peak at no more than -12 dBFS.

5.1.5. Audio compression: Programme audio should have good dynamic range, within the parameters listed above, but not be overly dynamic. While some compression may be needed to control the dynamic range of the programme audio, excessive audio compression of the final mix should be avoided as this reduces the perception of audio quality by the listener.

mandatory. 5.2.3.2. The Dolby-E stream shall be formatted such that the programme is in sync following

Dolby-E decoding using a DP572 or equivalent. 5.2.3.3. Maximum permissible audio peaks in a 5.1 or 5.0 soundtrack shall be -3dBFS

(+17dBm) 5.2.3.4. Although the Max dynamic range (max. peaks) for 5.1 channel mixes is considerably

higher than for Stereo-only LPCM mixes, it is understood that many 5.1 mixes will have a dynamics structure which more closely resembles a -10dBFS stereo mix in order to facilitate the simple creation of an Lt/Rt fold-down mix.

10. RF REQUIREMENT

As a baseline initial reading on a spectrum analyzer can be used to record the C/N+N and the level in dBm/Hz of the carrier. IRD reading of Es/No margin is recorded at the same points using a professional IRD. The aggregate power in dBm will be calculated from the dBm/Hz levels reading and the carrier symbol rate. On average, generally we require a C/N +N of 14 dB at our receiver end for proper signal lock and Es/No link margin of 8dB on 8-PSK DVB S2 modulation technique with a code rate of 3/4 and this should be used a baseline to meet of 99.99% availability Eb/No (energy per symbol to noise density) is a universal figure of merit for any kind of receiver, it is the measured at the receiver input terminals and is independent of anything inside that receiver and this figure is independent of the model of the receiver. Below is the minimum required Es/No to achieve the QEF (Quasi Error Free) transmission (assuming single carrier per transponder with an information rate of about 16-17Mbps and using DVBS-2 transmission scheme).



Code Rate Co/No = Es/No @ ASTRO (AABC/CBC) atQEF region

(BER = 1e-7)

QPSK 1/3 - 0.70 dB

QPSK 2/5 0.20 dB

QPSK 1/2 1.40 dB

QPSK 3/5 2.80 dB

QPSK 2/3 3.60 dB

QPSK 3/4 4.30 dB

QPSK 4/5 5.10 dB

QPSK 5/6 5.50 dB

QPSK 8/9 6.60 dB

QPSK 9/10 6.70 dB

8 PSK 3/5 6.30 dB

8 PSK 2/3 7.10 dB

8 PSK 3/4 8.40 dB

8 PSK 5/6 9.70 dB

8 PSK 8/9 11.10 dB

8 PSK 9/10 11.30 dB

Figure 14

The value derived above is estimated link margin computation figures, these figures may vary as it could be more link-specific. The channel supplier / Uplink provider are required to send more information in order for the receiver end to compute total Co/No = Es/No with additional margin commissioned for rain fade. The Header Es/No estimate is an indication of the C/N of the header symbols of the received DVB-S2 frames and a good representation of the received C/N of the signal Eb/No is the measure of signal to noise ratio for a digital communication system. It is measured at the input to the receiver and is used as the basic measure of how strong the signal is. Different forms of modulation -- BPSK, QPSK, QAM and others have different curves of theoretical bit error rates versus Eb/No as shown in Figure 15

Figure 15 BER vs. Eb/No

These curves show the communications engineer the best performance that can be achieved across a digital link with a given amount of RF power In such cases, we would need the service provider to disclose certain relevant information on their uplink side to perform an end-to-end link budget analysis



10.1 Bit Rate Compression requirement of a minimum of 12Mbps is required on the video bit rate on MPEG 4 compression platform. If Statistical Multiplexer is being is being deployed following settings need to be adhered on the video bit rate at the encoder level; Mpeg 4 platform a minimum 8Mbps and

maximum 16Mbps is required. This needs to be disclosed by the content provider.

10.2 Availability Analysis With the available Eb/No margin computed, the system degradation can be added for downlink fades caused by rain. At 99.99% availability, 40 degrees elevation, and 114 mm rain rate the ITU rain model predicts 0.96 dB rain attenuation (Lrain).

However, in addition to a decrease in the receive carrier level of 2.0 dB, the rain attenuation will also cause with an increase in the antenna noise temperature compared to clear sky conditions (depending of the mode code and also modulation technique).

The increase in antenna noise temperature will add to the clear sky system temperature. The corresponding increase in system noise temperature and degradation in receive system G/T is calculated as follows:

System Temp with rain = Tsystem = Tsystem_clear_sky + Train

Degradation in G/T = d(G/T) = Tsystem / Tsystem_clear_sky

Link Margin = Lrain + d(G/T)

Figure 16 summarizes the trade-off between the required link margin as a function of the receive system clear sky noise temperature. The terminal System Noise Temperature has been determined to be 218 K, extrapolating from Table 12 the required link margin is found to be approximately 3.0 dB. Based on the analysis, the margin required to sustain any of the channels would be 3 dB for availability of 99.99% (min value). This value will be used as a baseline for RF signal receptions. If this value is not adhere, there will be a possibility of signal degradation and video distortion at the receive end noticed during rain fade.

The vendor shall furnish the necessary simulation and test equipment (in the absence of signals and interfacing equipment from systems supplied by others) to demonstrate that his system meets performance specifications. A site acceptance test shall be conducted after the installation has been completed.

11.5. Site Acceptance Test

The vendor shall be responsible for planning, testing and executing the test plan. Prior to final system acceptance, all equipment and software supplied by the vendor must be factory tested and site tested. The initial test plan shall be delivered at the design review. If changes are required for the site testing, the vendor will seek the approval of MBNS and an updated site test plan shall be delivered to MBNS two weeks before site testing commences. The test plan should include testing on all required interfaces such as ASI, SDI, HD-SDI and Gigabit Ethernet. Site acceptance testing shall consist of performance measurements to ensure compliance with hardware, software and system specifications that shall be witnessed by MBNS. Should the system in its entirety or in part fail to meet hardware, software or system specifications, field adjustment shall be made. All performance specifications shall be met before the approval of the site acceptance test results. Three copies (sets) of the Site Acceptance Test document reports shall be delivered to MBNS within two weeks of completing site acceptance test.

11.6. Training

The vendor shall provide training for technical staff of MBNS to enable them to acquire the necessary knowledge and skill to operate and maintain the system. Training shall include: a. Basic training covering theory and design. b. Physical on-site training for operation/maintenance. The vendor shall carry out the actual training needs analysis.

Operations and maintenance (and troubleshooting) handbook d. Systems warranty and support schedule e. Systems documents (i.e. engineering drawings and schematic diagrams) f. Test plan, test data, results and reports.

Equipment and software supplied as part of the system handover shall be accompanied by a set of technical handbooks.

12. CONCLUSION

It is inherently difficult to define precisely what a suitable quality product is, and therefore there will be some subjective descriptions leading to imprecise advice. This is an unavoidable consequence of the rapid technical developments at this time. A competent resource provider should be able to give advice on achieving good quality results. Programmes of excellent technical quality have an inherent element of future proofing relative to those of a lower standard, and programme suppliers should bear this in mind.
