This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard will be essential to technically skilled people who work in the broadcasting environment and need to use sophisticated methods and equipment to install, set-up, operate and fault find professional broadcast head-end systems and equipment.
People credited with this standard will be able to:
  • Explain the fundamental principles of satellite television signal transmission and reception
  • Identify and explain the signal processing performed in a satellite television decoder;
  • Explain the fundamental principles of digital television signal transmission and reception;
  • Identify and explain the signal processing performed in a digital television decoder. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit value is based on the assumption that people starting to learn towards this unit standard already understand:
  • Television and video systems
  • Television receiver circuits 

  • UNIT STANDARD RANGE 
    Specific range statements are provided in the body of the unit standard where they apply to particular specific outcomes or assessment criteria

    ASSESSMENT CRITERION 3 
    The functions of the signal processing stages in a digital decoder are correctly identified and explained from a given block diagram on board level 

    ASSESSMENT CRITERION 4 
    The functions of the signal processing stages in a digital decoder are correctly identified and explained from a given circuit diagram on component level 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Providers of learning towards this unit standard will need to meet the accreditation requirements of the relevant ETQA
    Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.

    Moderation Option: The moderation requirements of the relevant SETA's ETQA must be met in order to award credit to learners for this unit standard 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Candidates are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the candidate's performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the unit standard

    The following embedded knowledge is addressed in an integrated way in the unit standard:
  • Satellite transmission principles including Satellite orbital positions, Transmission bands, Transponder channel bandwidths and polarization methods, E.R.P and carrier to noise ratio and Footprints for a given service area.
  • Satellite Reception Principles including Satellite dish size and position, Azimuth and elevation for a given satellite position, Function of the L.N.B and the importance of correct cable and connections to the satellite receiver.
  • Stages and functions within a typical satellite receiver

    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others (clients and colleagues) as a member of a team, group, organisation to achieve the required end-result 

    UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves in the work areas and their activities responsibly and effectively to complete tasks within deadlines 

    UNIT STANDARD CCFO COLLECTING 
    Collect and analyse digital television signal information and critically evaluate the effect of this on work performance 

    UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively (with clients and colleagues), using visual and / or language skills 

    UNIT STANDARD CCFO SCIENCE 
    Use science and technology (digital television signal transmission and reception equipment) effectively and critically showing responsibility towards the environment (work areas and venues) and health of others (clients and colleagues) 

    UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding that the world or work is a set of related systems and that problem-solving does not exist in isolation 

    UNIT STANDARD ASSESSOR CRITERIA 
    Assessors should keep the following principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the candidate is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriate, fair, manageable, integrated into work or learning, valid, direct, authentic, sufficient, systematic, open and consistent.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
