Description

Display device and method for video frame image

Technical Field

The present invention relates to the field of image display technologies, and in particular, to a display device and method for video frame images.

Background

In the field of TV/Monitor, the frame rate of the video to be played often does not match the refresh rate of the panel, so before sending the video to be played to the panel, it is usually necessary to output and display the video frame image contained in the video to be played according to the refresh rate of the panel by frame-rate-conversion (frame-rate-convert) technology, that is, the video frame image contained in the video to be played is firstly stored in the memory according to the frame rate of the video to be played, and then the video frame image stored in the memory is read according to the refresh rate of the panel, so that the video frame image contained in the video to be played is output and displayed according to the refresh rate of the panel.

Currently, for an active _3d image in an interlaced scene, each complete image is divided into two field signals (an upper field and a lower field), and each field signal is further divided into a left image and a right image (an L image and an R image), so for any video frame image included in an active _3d video in an interlaced scene, it is necessary to strip out four sub-images from the video frame image, store the four sub-images corresponding to the video frame image into a memory according to a video frame rate, and finally read the four sub-images stored in the memory according to a refresh rate of a panel. However, the data size of the identity information corresponding to the sub-images is large, and therefore, too much storage resources are occupied for storing the identity information corresponding to each sub-image _。

the current frame image is specifically a video frame image which needs to be output and displayed currently in a video formed by active _3d images in a current interlaced scanning scene, and for the active _3d images in the current interlaced scanning scene, each complete image is divided into two field signals (an upper field and a lower field), each field signal is divided into a left image and a right image (an L image and an R image), namely after the current frame image is stripped, four sub-images can be obtained, including the upper field left image, the upper field right image, the lower field left image and the lower field right image, and identity information corresponding to each sub-image, and for any sub-image, the identity information corresponding to the sub-image is used for indicating which of the upper field left image, the upper field right image, the lower field left image and the lower field right image the image specifically is, so that when the sub-images are stored in a memory after stripping, the identity information corresponding to each sub-image needs to be stored together; the target cache block is a cache block which is correspondingly stored for each sub-image corresponding to the current frame image, and when the cache block is set in the memory, identity tags are added to each cache block according to the sequence and specific quantity when a plurality of cache blocks are set, that is, each target cache block has a unique identity tag, and the reading sequence of the plurality of target cache blocks can be determined according to the identity tags in each cache block; wherein, the storage rate is a rate when the current video frame images are written into the memory one by the WDMA, the WDMA is an execution subject for directly writing the sub-images into the memory, the storage rate is related to the frame rates of the video source and the video, and the video source includes but is not limited to: the video source of the set top box, the U-disc, etc. determines the frame rate of the video differently, and the frame rate of the video determines the storage rate differently, so the storage rate of the video frame image can be determined by the frame rate of the video, for example, because one video frame image in the video formed by the active _3d image needs to be stripped into four sub-images, when the frame rate corresponding to the video is 30i, the corresponding storage rate is 120i, and when the frame rate corresponding to the video is 60i, the corresponding storage rate is 240i; the reading sequence is the sequence of the target cache blocks read by RDMA (remote direct memory Access), the RDMA is an execution subject for reading the sub-images in the memory, and the reading sequence of the target cache blocks can be determined by the identity tag of each target cache block, so that after the reading sequence is determined, the sub-images stored in the target cache blocks are sequentially read only on the basis of the preset reading rate, and the sub-images can be sequentially output and displayed; the preset reading rate is determined according to a refresh rate corresponding to a panel of the display device, for example, assuming that the refresh rate corresponding to the panel of the display device is 120HZ, the preset reading rate is 120i, and the display device includes but is not limited to: televisions, displays, etc.

In the embodiment of the present application, the specific implementation procedures of the processing unit 11, the storage unit 12, and the reading unit 13 are as follows: the method comprises the steps that a processing unit 11 strips a current frame image to obtain a plurality of sub-images corresponding to the current frame image and identity information corresponding to each sub-image, namely four sub-images corresponding to the current frame image, such as a sub-image A, a sub-image B, a sub-image C and a sub-image D, the identity information corresponding to the sub-image A is a top field left image, the identity information corresponding to the sub-image B is a top field right image, the identity information corresponding to the sub-image C is a bottom field left image, the identity information corresponding to the sub-image D is a bottom field right image, a storage unit 12 sequentially stores each sub-image into a target cache block corresponding to each sub-image according to the identity information corresponding to each sub-image and the storage rate, an identity tag used for representing the reading sequence of a target cache blocks is arranged in the target cache block, namely the target cache block 0 stored corresponding to the sub-image A is determined according to the identity tag, the target cache block 1 stored corresponding to the sub-image B, the target cache block 2 stored corresponding to the sub-image C is read according to the identity tag, the target cache block 3 stored to the sub-image B, and the target cache block C is read according to the reading sequence of the target cache block, and the preset reading sequence of the sub-image A, and the target cache block C, and the pre-image D, and the sub-image display.

The present application provides a display device of a video frame image, including: the device comprises a processing unit, a storage unit and a reading unit; firstly, a processing unit strips a current frame image to obtain a plurality of sub-images corresponding to the current frame image and identity information corresponding to each sub-image; secondly, the storage unit sequentially stores each sub-image into a target cache block corresponding to each sub-image according to the identity information corresponding to each sub-image and the storage rate, wherein the target cache block is provided with an identity tag used for representing the reading sequence of the target cache block; and finally, sequentially reading the sub-images stored in each target cache block by the reading unit according to the reading sequence corresponding to the target cache blocks and the preset reading rate, and sequentially outputting and displaying the plurality of sub-images. In the present application, for any one target cache block, the target cache block has an identity tag representing a reading order of the target cache block, that is, the reading order of a plurality of target cache blocks can be determined by the identity tag in each target cache block, that is, the sub-images stored in each target cache block can be sequentially read according to the reading order and the preset reading rate of the plurality of target cache blocks, and the plurality of sub-images can be output and displayed according to the reading order and the preset reading rate. Therefore, the identity information corresponding to each sub-image does not need to be additionally stored, and the storage resource is prevented from being excessively occupied by the identity information corresponding to the sub-images.

An embodiment of the present application further provides another display apparatus for displaying a video frame image, as shown in fig. 2, which is explained below with reference to fig. 2:

further, as shown in fig. 2, the apparatus further includes: a setting unit 14, configured to set, by the processing unit 11, a plurality of buffer blocks in a memory before performing a stripping process on a current frame image, where the number of buffer blocks is 4n and n is a positive integer; the generating unit 15 is configured to generate an identity tag corresponding to each cache block according to the number of the cache blocks and a setting sequence corresponding to the cache blocks; an adding unit 16, configured to correspondingly add each identity tag to each cache block.

Since each video frame image is stripped to obtain four sub-images, the number of the plurality of cache blocks needs to be set to be a multiple of 4 for storing the four sub-images corresponding to each video frame image, and the specific number of the plurality of cache blocks can be set according to user definition, which is not specifically limited in this embodiment, wherein the setting sequence corresponding to the plurality of cache blocks is the sequence in which the plurality of cache blocks are set in the memory, for example, block 0, block 1, and block 2 \8230aresequentially set in the memory, block 7, and the setting sequence of 8 blocks is (1) block 0, (2) block 1 \8230, or (8) block 7; the identity tag is specifically a binary tag, a first bit binary code (i.e., the lowest bit of the binary code) of the binary tag is used for representing left/right image information in the identity information corresponding to the sub-image that should be stored in the target cache block, a second bit binary code (i.e., the second lowest bit of the binary code) is used for representing top/bottom field information in the identity information corresponding to the sub-image that should be stored in the target cache block, other bit binary codes are used for representing position information of each target cache block in the plurality of cache blocks, and the specific number of bits of the binary tag is determined according to the number and the setting order of the plurality of cache blocks. Illustratively, when 4 cache blocks, namely block 0, block 1, block 2 and block 3, are sequentially arranged, and the corresponding arrangement sequence is (1) block 0, (2) block 1 \8230, (4) block 3, according to the generation rule of the binary tag, only two-bit binary codes can meet the uniqueness of the identity tag, namely block 0 corresponds to 00, block 1 corresponds to 01, block 2 corresponds to 10 and block 3 corresponds to 11; when 8 cache blocks, i.e., block 0, block 1, block 2, block 3, block 4, block 5, block 6, and block 7 are sequentially arranged, and the corresponding arrangement order is (1) block 0, (2) block 1 \8230, (8) block 7, according to the binary tag generation rule, three binary codes are required to satisfy the uniqueness of the identity tag, so that block 0 corresponds to 000, block 1 corresponds to 001, block 2 corresponds to 010, block 3 corresponds to 011, block 4 corresponds to 100, block 5 corresponds to 101, block 6 corresponds to 110, and block 7 corresponds to 111, and so on, a unique binary tag can be arranged for each cache block, in which case, when the first bit binary code (i.e., the lowest bit of the binary code) and the second bit binary code (i.e., the next lowest bit of the binary code) are 01, both the aforementioned block 1 and block 5 correspond, and if the third bit of the binary code is 0, the block 1 and the third bit of the block 5 are 1. As can be seen, the bit width of the binary tag is determined by the number of the plurality of cache blocks, and according to the first bit binary code (i.e., the lowest bit of the binary code) and the second bit binary code (i.e., the second lowest bit of the binary code) of the binary tag, what kind of the sub-image corresponding to the identity information is stored in each cache block can be determined, and then the binary codes of other bits are matched to determine the location information of the cache block, i.e., the location of the cache block in the plurality of cache blocks is determined, that is, after the identity tag corresponding to each cache block is generated according to the number of the plurality of cache blocks and the setting sequence corresponding to the plurality of cache blocks, each identity tag is correspondingly added to each cache block, and what kind of the sub-image corresponding to the identity information is stored in the cache block can be determined according to each identity tag.

In this embodiment, before the processing unit 11 performs the stripping processing on the current frame image, the setting unit 14 sets a plurality of buffer blocks in the memory, where the buffer blocks need to be set in the memory in advance, that is, the memory is divided into the plurality of buffer blocks according to a fixed memory capacity, the generating unit 15 generates an identity tag corresponding to each buffer block according to the number of the plurality of buffer blocks and a setting sequence corresponding to the plurality of buffer blocks, that is, generates an identity tag for reading a sequence of each buffer block, and the adding unit 16 correspondingly adds each identity tag to each buffer block, so as to add the identity tag to each buffer block, so as to determine what kind of sub-image of identity information is stored in the buffer block according to each identity tag.

Further, as shown in fig. 2, the storage unit 12 includes: the first determining module 121 is configured to determine a storage sequence corresponding to the plurality of sub-images according to the identity information corresponding to each sub-image; a second determining module 122, configured to determine, based on the identity information corresponding to each sub-image and the identity tag in each cache block, a target cache block corresponding to each sub-image; the storage module 123 is configured to sequentially store each sub-image into the target cache block corresponding to each sub-image according to the storage sequence and the storage rate corresponding to the plurality of sub-images.

The storage sequence is the sequence of storing the plurality of sub-images into the plurality of target cache blocks, and since the upper field LR needs to be read first and the lower field LR needs to be read later during reading, in order to ensure the reading efficiency, the storage sequence of the plurality of sub-images can be determined by the identity information corresponding to each sub-image, so that the upper field LR can be stored first and the lower field LR can be stored later; after the storage sequence of the multiple sub-images corresponding to the current image is determined, the cache block corresponding to each sub-image, that is, the target cache block, needs to be determined, and since each cache block has an identity tag used for representing the reading sequence, which cache block of the multiple cache blocks each sub-image corresponding to the current image needs to be stored in can be determined according to the identity tag, and after the target cache block is determined, the WDMA sequentially stores each sub-image into the target cache block corresponding to each sub-image according to the storage sequence and the storage rate corresponding to the multiple sub-images, that is, the sub-images corresponding to the reading sequence can be directly obtained during subsequent RDMA reading.

In this embodiment of the application, the storage unit 12 is configured to store each sub-image into the target cache block corresponding to each sub-image in sequence according to the identity information and the storage rate corresponding to each sub-image, and the specific storage process is as follows: the first determining module 121 determines a storage order corresponding to the plurality of sub-images according to the identity information corresponding to each sub-image, that is, an order in which the plurality of sub-images are stored in the plurality of target cache blocks, the second determining module 122 determines the target cache block corresponding to each sub-image based on the identity information corresponding to each sub-image and the identity tag in each cache block, that is, determines which cache blocks, that is, target cache blocks, each sub-image is stored in the plurality of cache blocks, and finally the storage module 123 sequentially stores each sub-image in the target cache block corresponding to each sub-image according to the storage order and the storage rate corresponding to the plurality of sub-images, so that the sub-images corresponding to the reading order can be directly obtained during subsequent RDMA reading.

Further, as shown in fig. 2, the storage module 123 is specifically configured to: detecting whether a subimage corresponding to the historical frame image is stored in each target cache block; if the subimages corresponding to the historical frame images are not stored in each target cache block, sequentially storing a plurality of subimages corresponding to the current frame image into the target cache block corresponding to each subimage according to the storage sequence and the storage rate; if the subimages corresponding to the historical frame images are stored in each target cache block, sequentially judging whether the subimages corresponding to the historical frame images in each target cache block are read or not according to the storage sequence; if the sub-image corresponding to the historical frame image is not read, when the sub-image corresponding to the historical frame image is completely read, the sub-image corresponding to the current frame image is stored in a corresponding target cache block in a covering mode according to the storage sequence and the storage rate; and if the sub-images corresponding to the historical frame images are read, covering and storing the sub-images corresponding to the current frame images into the corresponding target cache blocks according to the storage sequence and the storage rate.

When the number of the cache blocks is 4, that is, the target cache block corresponding to each sub-image corresponding to the current frame image and the target cache block corresponding to each sub-image corresponding to the previous frame image are the same 4 cache blocks, the historical frame image refers to the previous frame image, that is, the sub-image corresponding to the 3 rd frame image; when the number of the buffer blocks is 8, it is assumed that the target buffer block corresponding to each sub-image corresponding to the current frame image is the last 4 in the preset sequence, and then the historical frame image may refer to the last two frame images, that is, the sub-image corresponding to the 2 nd frame image, it needs to be described that, when the sub-image corresponding to the historical frame image is stored in each target buffer block, it needs to sequentially judge whether the sub-image corresponding to the historical frame image in each target buffer block is read according to the storage sequence, and then the sub-image corresponding to the current frame image is stored in the corresponding target buffer block in an overlapping manner according to the reading condition, and the specific storage modes include two types, the first type is to store the sub-image corresponding to the current frame image after it is sequentially detected that the sub-image corresponding to the historical frame image in the target buffer block is read, the second type is to store the sub-image corresponding to the current frame image in the target buffer block after the sub-image corresponding to the historical frame image in all target buffer blocks is read, but the sub-image corresponding to the current frame image in the current frame image is not read according to the sequence of the last field LR, and the current frame LR is not read, and therefore, the sub-image corresponding to the current frame LR is not read in the current frame LR in the target buffer block, and the current frame LR is not read in the first storage mode, and the second storage mode is not used for obviously, and the second storage efficiency is guaranteed.
