#region RFC2435 - The Type Field
/*
4.1. The Type Field
The Type field defines the abbreviated table-specification and
additional JFIF-style parameters not defined by JPEG, since they are
not present in the body of the transmitted JPEG data.
Three ranges of the type field are currently defined. Types 0-63 are
reserved as fixed, well-known mappings to be defined by this document
and future revisions of this document. Types 64-127 are the same as
types 0-63, except that restart markers are present in the JPEG data
and a Restart Marker header appears immediately following the main
JPEG header. Types 128-255 are free to be dynamically defined by a
session setup protocol (which is beyond the scope of this document).
Of the first group of fixed mappings, types 0 and 1 are currently
defined, along with the corresponding types 64 and 65 that indicate
the presence of restart markers. They correspond to an abbreviated
table-specification indicating the "Baseline DCT sequential" mode,
8-bit samples, square pixels, three components in the YUV color
space, standard Huffman tables as defined in [1, Annex K.3], and a
single interleaved scan with a scan component selector indicating
components 1, 2, and 3 in that order. The Y, U, and V color planes
correspond to component numbers 1, 2, and 3, respectively. Component
1 (i.e., the luminance plane) uses Huffman table number 0 and
quantization table number 0 (defined below) and components 2 and 3
(i.e., the chrominance planes) use Huffman table number 1 and
quantization table number 1 (defined below).
Type numbers 2-5 are reserved and SHOULD NOT be used. Applications
based on previous versions of this document (RFC 2035) should be
updated to indicate the presence of restart markers with type 64 or
65 and the Restart Marker header.
The two RTP/JPEG types currently defined are described below:
horizontal vertical Quantization
types component samp. fact. samp. fact. table number
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| | 1 (Y) | 2 | 1 | 0 |
| 0, 64 | 2 (U) | 1 | 1 | 1 |
| | 3 (V) | 1 | 1 | 1 |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| | 1 (Y) | 2 | 2 | 0 |
| 1, 65 | 2 (U) | 1 | 1 | 1 |
| | 3 (V) | 1 | 1 | 1 |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
These sampling factors indicate that the chrominance components of
type 0 video is downsampled horizontally by 2 (often called 4:2:2)
while the chrominance components of type 1 video are downsampled both
horizontally and vertically by 2 (often called 4:2:0).
Types 0 and 1 can be used to carry both progressively scanned and
interlaced image data. This is encoded using the Type-specific field
in the main JPEG header. The following values are defined:
0 : Image is progressively scanned. On a computer monitor, it can
be displayed as-is at the specified width and height.
1 : Image is an odd field of an interlaced video signal. The
height specified in the main JPEG header is half of the height
of the entire displayed image. This field should be de-
interlaced with the even field following it such that lines
from each of the images alternate. Corresponding lines from
the even field should appear just above those same lines from
the odd field.
2 : Image is an even field of an interlaced video signal.
3 : Image is a single field from an interlaced video signal, but
it should be displayed full frame as if it were received as
both the odd & even fields of the frame. On a computer
monitor, each line in the image should be displayed twice,
doubling the height of the image.

The Length field is set to the length in bytes of the quantization
table data to follow. The Length field MAY be set to zero to
indicate that no quantization table data is included in this frame.
See section 4.2 for more information. If the Length field in a
received packet is larger than the remaining number of bytes, the
packet MUST be discarded.
When table data is included, the number of tables present depends on
the JPEG type field. For example, type 0 uses two tables (one for
the luminance component and one shared by the chrominance
components). Each table is an array of 64 values given in zig-zag
order, identical to the format used in a JFIF DQT marker segment.
For each quantization table present, a bit in the Precision field
specifies the size of the coefficients in that table. If the bit is
zero, the coefficients are 8 bits yielding a table length of 64
bytes. If the bit is one, the coefficients are 16 bits for a table
length of 128 bytes. For 16 bit tables, the coefficients are
presented in network byte order. The rightmost bit in the Precision
field (bit 15 in the diagram above) corresponds to the first table
and each additional table uses the next bit to the left. Bits beyond
those corresponding to the tables needed by the type in use MUST be
ignored.
