VIDEO TRANSMISSION METHOD, DEVICE, AND SYSTEM, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18150980 titled 'VIDEO TRANSMISSION METHOD, DEVICE, AND SYSTEM, AND STORAGE MEDIUM
Simplified Explanation
Abstract: A video transmission method is described in which a first media gateway receives an uplink media packet from a first terminal. The uplink media packet includes information indicating that the first terminal supports different resolutions for uplink and downlink streams. The first media gateway sends a downlink media packet to the first terminal, carrying a downlink media stream of a different resolution. The method allows for adjusting the resolution based on channel quality and network resources.
Explanation:
- The method involves transmitting video between a first terminal and a media gateway.
- The first terminal supports different resolutions for uplink (sending) and downlink (receiving) streams.
- The first terminal sends an uplink media packet to the media gateway, indicating its resolution capabilities.
- The media gateway sends a downlink media packet to the first terminal, containing a downlink media stream of a different resolution.
- The resolution can be adjusted based on the quality of the channel and the availability of network resources.
Potential Applications:
- Video calling applications that require adaptive resolution based on network conditions.
- Video conferencing systems that need to optimize video quality based on available resources.
- Streaming services that dynamically adjust video resolution to ensure smooth playback.
Problems Solved:
- In video transmission, it is important to adapt the resolution based on network conditions and available resources.
- Traditional methods may not support different resolutions for uplink and downlink streams.
- This method solves the problem of efficiently transmitting video by adjusting the resolution as needed.
Benefits:
- Allows terminals to support different resolutions for sending and receiving video streams.
- Enables adaptive resolution based on channel quality, ensuring optimal video delivery.
- Optimizes network resource utilization by raising or lowering the resolution as necessary.
Original Abstract Submitted
A video transmission method includes: A first media gateway receives an uplink media packet sent by a first terminal, where the uplink media packet carries information indicating that the first terminal supports an uplink-downlink resolution asymmetry capability and an uplink media stream of a first resolution of the first terminal. The first media gateway sends a first downlink media packet to the first terminal, where the first downlink media packet carries a downlink media stream of a second resolution of the first terminal, and the first resolution is different from the second resolution. The solution is applicable to the following case: In a video call process, a terminal that supports different resolutions in a sending direction and a receiving direction can lower a resolution based on channel quality to deliver a video packet, and can raise a resolution when network resources are sufficient.
