MPEG-2 transport streams convey one or more programs of coded data, and can be constructed

9、 from one or more elementary coded data streams, program streams, or other transport streams. This document specifies a method to transport uncompressed video streams within an MPEG-2 transport stream using existing SMPTE ST 302 for audio and SMPTE ST 2038 for ancillary data. 1 Scope This document o

10、utlines the architecture and structure of changes to the existing broadly used MPEG-2 transport stream specification to accommodate efficient transmission of uncompressed video over MPEG-2 transport stream. It details how uncompressed video is packed into an elementary stream and PES stream. It outl

11、ines an encapsulation structure for carrying uncompressed video over transport streams and relies on existing SMPTE ST 302, SMPTE ST 2038, ITU-T Recommendation H.222.0 / ISO/IEC 13818-1 for PAT, PMT and PID management structures. 2 Normative References The following standards contain provisions that

15、o-ordinate Convention All references to line numbers and pixel numbers shall follow this convention: The first line of the frame is line 0. Line numbers increment by 1 for each subsequent line of the frame. At the beginning of the next frame the line number reverts to 0. The first pixel of the line

16、is pixel 0. Pixel numbers increment by 1 for each subsequent pixel of the line. At the beginning of the next line the pixel number reverts to 0. The active picture is right-justified. The last active pixel of a line is also the last pixel of that line. The horizontal blanking region starts at pixel

SMPTE RDD 37:2016 Page 4 of 18 pages 5 Program Map Table (PMT) Video Section The Program Map Table shall conform to J2K video descriptor defined in ITU-T Recom

18、mendation H.222.0 / ISO/IEC 13818-1 with the following exceptions: The descriptor_tag shall have a value of 224 to indicate an uncompressed video descriptor. The stream_type shall have a value of 0xEA to indicate an uncompressed video stream. The profile_and_level field shall be 0. The vertical_size

19、 field shall indicate the total number of active lines in the video frame. The max_bit_rate field may be 0. The max_buffer_size field may be 0. The private_data_byte section shall be formatted as described below Table 1 Private Data Bytes in Video Descriptor Private_data_bytes() total_horizontal_siz

At the last line of the vertical active region of each field, the final video_data_segment shall contain padding_bits in the precise quantity required to completely fill the final

22、 transport_packet of that line. The padding_bits may be any value. The padding_bits shall be ignored by the receiver. pixel_data: The pixels of the active picture are scanned horizontally from left to right across the horizontal active part of each line in the extended vertical active region. The pi

23、xel_data components shall be sent in the same order as its native serial format. For example, 4:2:2 SDI video components SMPTE RDD 37:2016 Page 17 of 18 pages are transmitted in the order Cb, Y, Cr, Y. Likewise, the pixel_data would be sent as Cb, Y, Cr, Y. The pixel_data shall be transmitted most s
