Description
It is on May 15th, 2013 that the present invention, which is application No. is the 201310183439.8, applying date, entitled " use
The divisional application of the patent of the decoded ultra high-definition digital television receiver of HEVC video ".
Technical field
The present invention relates to ultra high-definition digital TV fields more particularly to a kind of use efficient video coding HEVC video to decode
Ultra high-definition digital television receiver.
Background technique
Ultra high-definition (Ultra High-Definition) comes from International Telecommunication Union (International
Telecommunication U nion) formal name by " 4K resolution ratio (3840 × 2160 pixel) " of approval is set to
" ultra high-definition Ultra HD (Ultra High-Definition) ".Simultaneously this title be also applied for " 8K resolution ratio (7680 ×
4320 pixels) ".And technical high definition television resolution ratio is the physical resolution of 1920*1080 at present.But the following piece
Source capacity be also it is huge, 18 minutes uncompressed videos reach 3.5TB.High resolution ratio bring is exactly incredible
Fine and smooth display effect, in play pieces, superior camera lens can almost mirror the overall picture in a city, and every in camera lens
One details, can see clearly and understand Chu.In addition to resolution ratio, ultra high-definition LCD TV is worth that people is allowed to pay attention to there are also a bit --- it
Pixel density be up to 103ppi, although this index only has the one third of 4 screen of iPhone, than nowadays 60
The 36ppi high of inch 1080P TV is mostly.
But in existing some high definition television, resolution ratio insufficient, lesser limit of channel transmission bandwidth by data compression ratio
System, that is, allow to the video image and audio that design ultra high-definition resolution ratio, such as the image of 15360 × 8640 resolution ratio, often
The audio signal of the sample rate of sound channel 48KHz, but the limitation due to compressing inadequate and existing channel transmission mode, lead to nothing
Method sends and receives ultra high-definition digital television signal, and the lower audio-video signal of resolution ratio can only be selected to be watched, even if
The video image of ultra high-definition resolution ratio and the technology of audio itself have developed into it is ripe, in addition, due in DVB broadcast singal by word
Curtain is propagated as the specific content independently of audio, video, has certain professional and complexity, market to its reception
Upper few digital television receivers with subtitle processing are on sale.
Therefore, it is necessary to a kind of digital television receivers of ultra high-definition digital television signal, and original transmission machine is transformed
System is the view of ultra high-definition resolution ratio using the higher Audio data compression mode of data compression ratio and video data compression mode
The transmission of frequency image and audio creates conditions, while using terrestrial television channel transmission mode, is even if in mobile traffic
In televiewer, can also receive the video content and audio content of ultra high-definition resolution ratio, and rise specially to DVB broadcast singal
In subtitle carry out parsing and decoding process, by caption function be added ultra high-definition digital television signal digital television receiver
In.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of numbers of terrestrial channel transmission of ultra high definition digital television signal
Receiver carries out compression coding and decoding to ultra high-definition digital audio and video signals using spatial audio coding SAC coding, using efficient video
It encodes HEVC coding and compression coding and decoding is carried out to ultra high-definition digital video signal, while original terrestrial television channel has been transformed and has passed
Transferring technology creates condition for the transmission of ultra high-definition TV, so that televiewer can not only receive more and more TV programme,
And the resolution ratio of received TV programme is substantially increased, perfect seeing and hearing enjoyment is provided for the sense organ of televiewer, in addition,
Increase special subtitle processing module and subtitle processing buffer area in receivers, allows users to the subtitle for watching multiplicity
Information.

Video compression standard.In October, 2004, H.264/AVC group investigates potential various technologies.In January, 2005
In the meeting of VCEG, VCEG starts to specify certain themes to be that " key technology " is for further study.Establishment software code in 2005
Library is known as Key Technical Areas (KTA) and is used to assess these new " key technologies ".The software of KTA is in joint mould
On the basis of type (JM) by MPEG and VCEG video group develop jointly, project name fix tentatively for H.265 with H.NGVC (Next-
Generation Video Coding), this project was finally evolved into 2010 and is also referred to as by VCEG and MPEG joint venture
HEVC(High efficiency video coding).In January, 2010, VCEG and MPEG start initiating video compression technology just
Formula motion.The relevant technologies are by Video coding joint group (Joint Collaborative Team on Video Coding (JCT-
VC it)) reviews and assesses, conference is held in the cooperative groups first session in April, 2010, and one shares 27 complete motions.
Evaluation result shows that some motions can achieve the bit rate for using half in many test cases and maintain H.264/AVC phase
Same visual quality.In current meeting, joint project name renames as efficient Video coding (HEVC), and JCT-VC is small
Group is integrated into the relevant technologies one software code base and received text draft specification, and carries out further experiment, with assessment
Various functions.
Wherein, subtitle refers to non-visual contents such as dialogues inside written form display TV, film, stage works,
Refer to the text of films and television programs post-production.The voice content of program is shown in a manner of subtitle, hearing can be helped weaker
Spectators understand programme content.In addition, subtitle can be used for translation foreign language program, allows the spectators for not understanding the foreign language, can hear
The vocal cords of original work, while understanding programme content.The translation of the foreign language dialogue occurred below movie screen or television screen
Or other explain text and various texts, if the title of film, credits present, libretto, dialogue, declarer are to there is personage Jie
It continues, place name and age etc..
Wherein, PES stream is DTV elementary stream, in digital TV broadcast signal.Wherein, emit in signal
Audio, video and other additional datas are carried out data compression by MPEG-2 encoder, form elementary stream by end, that is,
ES stream, ES stream are packed into the code stream with packet header again, are exactly PES (Packetized Elementary Streams), that is, beat
The elementary stream of packet.Briefly, PES is that ES stream is packaged, and is formed along with packet header.
