Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the video transmission method and apparatus provided by the present disclosure, an application scenario related to each embodiment in the present disclosure is first introduced, where the application scenario includes a sending end that sends video data and a receiving end that receives video data in a video transmission process. The sending terminal may be any server in the internet or other types of data terminals, and the receiving terminal may be any display device having an eyeball tracking function (for example, an eyeball tracking sensor capable of determining an eyeball focus position may be provided), such as a terminal of a smart phone, a tablet computer, a smart television, a portable computer, a desktop computer, or the like, and may also be devices such as VR (Virtual Reality, chinese) glasses, AR (Augmented Reality, english) glasses, and the like.
Fig. 1 is a flowchart illustrating a video transmission method according to an exemplary embodiment, where the method is applied to a transmitting end, as shown in fig. 1, and the method includes:
step 101, receiving a target area sent by a receiving end, where the target area is an area where a user's gazing area corresponds to a video to be sent.
for example, the sending end receives a target area sent by the receiving end, the range indicated by the target area is based on a video to be sent, that is, the receiving end determines a watching area of a user on a display interface according to a position where eyeballs of the user pay attention to, and then obtains an area of the watching area corresponding to the video to be sent. The target area may include: the resolution of the display interface of the receiving end and the size of the watching area, and the resolution of the video to be sent are known by both the receiving end and the sending end, so that the target area can be determined according to the resolution of the display interface, the size of the watching area and the resolution of the video to be sent. The target area can also comprise the proportion of the watching area to the display interface of the receiving end, and then the target area is determined according to the resolution of the video to be sent. The receiving end may send the target area to the sending end according to a preset time interval.
and 102, coding the video to be transmitted according to the target area.
and 103, sending the coded video to a receiving end.
For example, according to the target region, the video to be transmitted may be divided into two parts, i.e., video information corresponding to the target region and video information corresponding to the non-target region, and the two parts of video information are encoded respectively. For example, the video information corresponding to the target area may be encoded according to a high-bit-rate encoding method, and the video information corresponding to the non-target area may be encoded according to a low-bit-rate encoding method, so as to reduce the bit rate and the occupied bandwidth in the whole video transmission process, or when the video information corresponding to the target area is encoded, the proportion of I frames (independent frames with all information, namely, key frames) in the whole packet or the whole block is high, and when the video information corresponding to the non-target area is encoded, the proportion of I frames is low. And combining the two parts of coded video information into a coded video according to the position relation. And the sending end sends the coded video to the receiving end.
therefore, the information content of the part corresponding to the target area in the coded video is high, correspondingly, the image quality obtained after decoding by the receiving end is higher and clearer, the information content of the part corresponding to the non-target area is low, correspondingly, the image quality obtained after decoding by the receiving end is low, so that the display interface of the receiving end can display images with different qualities according to the positions concerned by eyeballs of a user, the high-quality images of the watching area are ensured, and the bit rate and the bandwidth of video transmission are reduced.
in summary, in the present disclosure, a receiving end sends a target area, which is an area where a user gazes at the receiving end and corresponds to a video to be sent, to a sending end at preset time intervals, after the sending end receives the target area, video information corresponding to the target area and a non-target area in the video to be sent is respectively encoded, the encoded video is sent to the receiving end, the receiving end receives the encoded video, and the video information corresponding to the target area and the non-target area in the encoded video is respectively decoded according to the target area. The bit rate of video transmission can be reduced on the premise of ensuring the definition and fluency of videos in a watching area of a user, so that the bandwidth occupied by the video transmission is reduced.
Fig. 2 is a flow chart illustrating another video transmission method according to an example embodiment, as shown in fig. 2, step 102 includes:
and step 1021, encoding the video information corresponding to the target area in the video to be transmitted by using the first encoding scheme.
and 1022, encoding video information corresponding to other areas except the target area in the video to be transmitted by using a second encoding scheme.
wherein the quality of the video information encoded in the first encoding scheme is better than the quality of the video information encoded in the second encoding scheme.
for example, a video to be transmitted in a transmitting end is divided into two parts according to a target region, and different coding schemes are respectively selected, wherein one part is that video information corresponding to the target region corresponds to a first coding scheme, and the other part is that video information corresponding to other regions except the target region corresponds to a second coding scheme. In the same video information, the quality of the video information encoded by the first encoding scheme is better than that of the video information encoded by the second encoding scheme, that is, the first encoding scheme has higher encoding efficiency than the second encoding scheme, or the first encoding scheme has higher bit rate than the second encoding scheme. For example, the first coding scheme may be a coding scheme with a bit rate of 1.5Mbps under the h.264 coding standard, and the second coding scheme may be a coding scheme with a bit rate of 1Mbps under the h.264 coding standard. And coding the video information corresponding to the target area according to a coding scheme with the bit rate of 1.5Mbps, coding the video information corresponding to other areas except the target area according to a coding scheme with the bit rate of 1Mbps, and combining the two parts of coded video information into a coded video according to a position relation.
optionally, the watching area is an area determined by the receiving end according to a focus point of the eyeball of the user on the display interface of the receiving end and a preset distance.
for example, when a user uses a receiving end, an eyeball focuses on a display interface of the receiving end, the receiving end collects a position where the eyeball focuses on the user in real time (for example, the position where the eyeball focuses on is obtained according to an eyeball tracking sensor), and a circular or rectangular area is determined as a focusing area by taking the position where the eyeball focuses on as a center and taking a preset distance as a radius.
in summary, in the present disclosure, a receiving end sends a target area, which is an area where a user gazes at the receiving end and corresponds to a video to be sent, to a sending end at preset time intervals, after the sending end receives the target area, video information corresponding to the target area and a non-target area in the video to be sent is respectively encoded, the encoded video is sent to the receiving end, the receiving end receives the encoded video, and the video information corresponding to the target area and the non-target area in the encoded video is respectively decoded according to the target area. The bit rate of video transmission can be reduced on the premise of ensuring the definition and fluency of videos in a watching area of a user, so that the bandwidth occupied by the video transmission is reduced.
Fig. 3 is a flowchart illustrating a video transmission method according to an exemplary embodiment, as shown in fig. 3, applied to a receiving end, the method including:
Step 201, acquiring a gazing area of a user according to a focus point of eyeballs of the user on a display interface of a receiving end and a preset distance.
For example, when the user uses the receiving end, the eyeball focuses on the display interface of the receiving end, the receiving end collects the focused position of the eyeball of the user on the display interface in real time (for example, the focused position of the eyeball is obtained according to the eyeball tracking sensor), and then a circular or rectangular area is determined as the focusing area by taking the focused position of the eyeball as the center and taking the preset distance as the radius. Taking the receiving end as VR glasses as an example, after the user wears the VR glasses, a circular area is determined as a watching area according to the focused position of the eyeball of the user on the screen of the VR glasses, with the point as the center and the preset distance as the radius.
Step 202, determining a region of the watching region corresponding to the video to be sent as a target region.
For example, the target area may be determined according to the resolution of the display interface of the receiving end, the size of the gazing area, and the known resolution of the video to be transmitted. The ratio of the watching region to the display interface of the receiving end can be determined, and then the target region can be determined according to the resolution of the video to be sent. For example, the resolution of the display interface is 800 × 600, the gaze region is a rectangular region of 200 × 200 at the center of the display interface, the resolution of the video to be transmitted is 1600 × 1200, and the target region is a rectangular region of 400 × 400 at the center of the video to be transmitted.
step 203, sending the target area to the sending end at preset time intervals.
For example, the receiving end may collect a position where the eyeballs of the user pay attention to in real time, and send the target area to the sending end at a preset time interval, where the time interval may be predetermined by the sending end and the receiving end when the video transmission process starts, and may also be adjusted in real time according to the change degree of the watching area, for example, when the speed of the eyeballs of the user moving is fast, the time interval may be reduced, and when the eyeballs of the user moving slowly, the time interval may be increased, so as to ensure the definition and the smoothness of the video of the watching area of the user.
Step 204, receiving the encoded video sent by the sending end.
Step 205, decoding the encoded video according to the target region.
For example, the receiving end receives the encoded video transmitted by the transmitting end, and decodes the encoded video according to the target region determined in step 203. According to the target area, the video to be transmitted can be divided into two parts, namely video information corresponding to the target area and video information corresponding to the non-target area, and the two parts of video information are decoded respectively. The decoding scheme may be agreed with the sending end before the video transmission starts, or the sending end informs the receiving end in the video transmission process.
fig. 4 is a flow chart illustrating another video transmission method according to an example embodiment, as shown in fig. 4, step 205 includes:
step 2051 decodes, in the encoded video, video information corresponding to the target area in the first decoding scheme.
Step 2052 decodes, in the encoded video, video information corresponding to a region other than the target region in the first decoding scheme.
Wherein the quality of the video information decoded in the first decoding scheme is better than the quality of the video information decoded in the second decoding scheme.
for example, the encoded video is decoded by a first decoding scheme and a first decoding scheme agreed with the transmitting end, the video information corresponding to the target region corresponds to the first decoding scheme, and the other part corresponds to the second decoding scheme corresponding to the video information corresponding to the other region except the target region, wherein the same video information, the quality of the video information decoded by the first decoding scheme is better than that of the video information decoded by the second decoding scheme, that is, it can be understood that the decoding efficiency of the first decoding scheme is higher than that of the second decoding scheme, or the bit rate of the first decoding scheme is higher than that of the second decoding scheme. Taking the embodiment shown in fig. 2 as an example, in the encoded video sent by the sending end, the first coding scheme may be a coding scheme with a bit rate of 1.5Mbps under the h.264 coding standard, and the second coding scheme may be a coding scheme with a bit rate of 1Mbps under the h.264 coding standard. Accordingly, the first decoding scheme is a decoding scheme with a bit rate of 1.5Mbps in the h.264 coding standard, and the second decoding scheme may be a decoding scheme with a bit rate of 1Mbps in the h.264 coding standard, that is, video information corresponding to the target region is decoded according to the decoding scheme with a bit rate of 1.5Mbps, and video information corresponding to regions other than the target region is decoded according to the decoding scheme with a bit rate of 1 Mbps.
In summary, in the present disclosure, a receiving end sends a target area, which is an area where a user gazes at the receiving end and corresponds to a video to be sent, to a sending end at preset time intervals, after the sending end receives the target area, video information corresponding to the target area and a non-target area in the video to be sent is respectively encoded, the encoded video is sent to the receiving end, the receiving end receives the encoded video, and the video information corresponding to the target area and the non-target area in the encoded video is respectively decoded according to the target area. The bit rate of video transmission can be reduced on the premise of ensuring the definition and fluency of videos in a watching area of a user, so that the bandwidth occupied by the video transmission is reduced.
