37Overview
38The RF Modulator (RFM) converts a NTSC/PAL compliant digital video source
39and a Pulse Code Modulated (PCM) audio source into an analog composite
40television signal which is suitable for demodulation by a television
41demodulator. The digital video source (video input into RFM) is assumed
42to come from Video Encoder (VEC) core. The PCM audio source
43(audio input into RFM) is assumed to come from HiFiDAC core.
44
45
46Design
47The design for BRFM PI API is broken into two parts.
48
49o Part 1 (open/close/configuration):
50
51    These APIs are used for opening and closing BRFM device/device channel.
52    When a device/device channel is opened, the device/device channel can be
53    configured.
54
55o Part 2 (get/set):
56
57    These APIs are used for getting and setting runtime attributes of BRFM.
58
59
60Usage
61The usage of BRFM involves the following:
62
63   * Configure/Open of BRFM
64
65      * Configure BRFM device for the target system
66      * Open BRFM device
67
68   * Program device channel
69
70      * Program output channel
71      * Program output modulation type
72      * Program enable output
73
74
75Interrupt Requirements
76This module requires L2 interrupts. They are handled internally
77by the RFM PI.

329Description:
330    This enumeration defines the audio encoding.
331    Audio encoding supports BTSC analog standard.  BTSC analog standard
332    contains three BTSC variations: BTSC-USA, BTSC-EIA-J, and BTSC-Zweiton-M.
333    Rf Modulator only support BTSC-USA.  Countries that use BTSC USA
334    standard are: United States, Canada, Mexico, Brazil, and Taiwan.
335    BTSC-EIA-J is used in Japan, BTSC-Zweiton-M is used in South Korea.
336
337    Pal audio encoding only support mono.

364        50us, 50kHz: PAL
365
366    ====================== Application Notes ==================================
367    *** Note:It is recommended NOT to use Mono+SAP mode of BTSC Decoder.
368    From a STB System point-of-view, Mono+SAP mode can cause problems.  If you
369    use Mono+SAP mode, the STB System software must make sure to route either
370    main audio program (Mono component) or secondary audio program (SAP component)
371    to the audio DAC.  Only one of the audio program can be routed to audio DAC,
372    otherwise the output on the audio DAC will be unpredictable.  If you do use
373    Mono+SAP mode, which we don't recommend, then Rfm should be set to
374    BRFM_AudioEncoding_eSapMono.
375    -------------------- For NTSC-USA applications: ---------------------------
376    We recommend keeping Rfm Audio Encoding in BRFM_AudioEncoding_eStereo mode
377    for NTSC-USA applications.  In this mode, Rfm output would work for
378    Digital Signal and Analog Signal (BTSC Stereo, BTSC Mono, BTSC SAP only).
379    -------------------- For NTSC-Japan applications: --------------------------
380    We recommend keeping Rfm Audio Encoding in BRFM_AudioEncoding_eJpMono2 mode.
381    -------------------- For PAL applications: ---------------------------------
382    We recommend keeping Rfm Audio Encoding in BRFM_AudioEncoding_eMono mode.
