GDC21D301A

PSI_n’ s

data

Buffer

Write

Pointer

Same as Read pointer register. This value should

be located between start and end pointer. It is

recommended that this initial value is the same of

start pointer value. (See Round Buffer register

0x005)

Channel buffer pointer (0x700 ~ 0x706)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store FEC input data.

the

GDC21D301A will read the data from this buffer

to decode TS packets. The read pointer is used to

read data.

Audio compressed data buffer pointer

(0x708 ~ 0x70e)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store the data which is sent to

external audio decoder. the GDC21D301A will

read the data from this buffer to send them to

external audio decoder. The read pointer is used to

read data.

Audio

PES_extension

data

buffer

pointer(0x710 ~ 0x716)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store the PES_extension data

of audio packets. Before storing the PES_extension

data, the GDC21D301A writes the size of the

PES_extension data + stuffing_bytes. The read

pointer is not used by the GDC21D301A.

Video PES_extension data buffer pointer

(0x718 ~ 0x71e)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store the PES_extension data

of video packets. Before storing the PES_extension

data, the GDC21D301A writes the size of the

PES_extension data + stuffing_bytes. The read

pointer is not used by the GDC21D301A.

Auxiliary compressed data buffer pointer

(0x720 ~ 0x726)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store the data which is sent to

external auxiliary decoder. the GDC21D301A will

read the data from this buffer to send them to

external auxiliary decoder. The read pointer is used

to read data.

Auxiliary

PES_extension

data

buffer

pointer (0x728 ~ 0x72e)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store the PES_extension data

auxiliary

packets.

Before

storing

the

PES_extension data, the GDC21D301A writes the

size of the PES_extension data + stuffing_bytes.

The read pointer is not used by the GDC21D301A.

Transport_private_data

buffer

pointer

(0x730 ~ 0x736)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store transport_private_data

field. The read pointer is not used by the

GDC21D301A.

Adf_extension_data

buffer

pointer

(0x738 ~ 0x73e)

Same as PSI_n’s data buffer pointer register.

This buffer is used to store Adf_extension_data

field. The read pointer is not used by the

GDC21D301A.
