/*
* Terminology used in specification:
* data-burst - IEC61937 frame, contains header and encapsuled frame
- * burst-preambule - IEC61937 frame header, contains 16-bits words named Pa, Pb, Pc and Pd
+ * burst-preamble - IEC61937 frame header, contains 16-bit words named Pa, Pb, Pc and Pd
* burst-payload - encapsuled frame
* Pa, Pb - syncword - 0xF872, 0x4E1F
* Pc - burst-info, contains data-type (bits 0-6), error flag (bit 7), data-type-dependent info (bits 8-12)
* DTS type IV (DTS-HD) can be transmitted with various frame repetition
* periods; longer repetition periods allow for longer packets and therefore
* higher bitrate. Longer repetition periods mean that the constant bitrate of
- * the outputted IEC 61937 stream is higher.
+ * the output IEC 61937 stream is higher.
* The repetition period is measured in IEC 60958 frames (4 bytes).
