Digital TV over satellite: Depending on compression/modulation technique, digitized television typically requires a gross bit rate in which range (in millions of bits per second)? Select the best-known textbook range.

Introduction / Context:
Satellite television bit rates depend on source format, compression standard (e.g., MPEG families), Forward Error Correction overhead, and transponder characteristics. Classic exam questions cite a broad range for digitized TV to test order-of-magnitude understanding.

Given Data / Assumptions:

• Digitized TV involves source coding plus channel coding.
• Bandwidth/bit-rate planning considers transponder bandwidth and link budget.
• We select a representative range widely quoted in foundational texts.

Concept / Approach:

Historically, digitized TV services (standard and high definition with earlier codecs) have occupied tens of megabits per second per program/multiplex before efficiency improvements. The 30–82.5 Mb/s span captures the traditional envelope often referenced in exam material.

Step-by-Step Solution:

Verification / Alternative check:

Training literature for satellite broadcast systems shows comparable ranges prior to newer codecs; modern systems may achieve lower rates, but the exam-oriented range remains valid historically.

Why Other Options Are Wrong:

• 40–92.5 and 25–60 Mb/s: plausible but not the frequently cited canonical span.
• 2 Mb/s: far too low as a single fixed value for full TV channels in classic systems.

Common Pitfalls:

Confusing modern highly compressed OTT/terrestrial bit rates with legacy satellite broadcast bit rates used in exam questions.

Final Answer:

30 to 82.5 Mb/s
