Abstract: A method for providing error-resilient video content may include receiving video data reflective of multiple video frames; encoding the video data to generate a plurality of packets representing a video frame; transmitting the first group of packets to at least two receivers (110); receiving feedback information regarding receiving status of respective ones of the plurality of packets; examining error indications regarding the at least two receivers (110) based on the feedback information and implementing a first error-correction policy if a variation in the error indications among the at least two receivers (110) is below a first error threshold and a second error-correction policy if the variation is above the first error threshold. At least one of the first and second error-correction policies includes transmitting or retransmitting at least one packet using a coding scheme different from a scheme in encoding the plurality of packets already.
Abstract translation: 用于提供错误恢复视频内容的方法可以包括：接收反映多个视频帧的视频数据; 编码视频数据以生成表示视频帧的多个分组; 将第一组分组传送到至少两个接收器（110）; 接收关于所述多个分组中的相应分组的接收状态的反馈信息; 基于所述反馈信息检查关于所述至少两个接收器（110）的错误指示，并且如果所述至少两个接收器（110）之间的所述错误指示的变化低于第一错误阈值，则执行第一错误校正策略， 纠错策略，如果变化高于第一个错误阈值。 第一纠错策略和第二纠错策略中的至少一个包括使用与已编码多个分组中的方案不同的编码方案来传送或重传至少一个分组。
