摘要： Examples are disclosed for transmitting video content. In some examples, cyclic redundancy check (CRC) values may be added to video content for video frames to be presented or displayed in a given region of a display. Results of CRC functions for consecutive video frames that use the added CRC values may be compared to determine whether the video content for the consecutive video frames is static video content. Video content for at least one of the consecutive video frames may be withheld from being transmitted if the video content for the consecutive video frames is characterized as static video content. Multiple CRC values or different CRC values may be added to further determine whether video content for the consecutive video frames or for subsequent consecutive video frames is also characterized as static video content. Other examples are described and claimed.

摘要： Two or more video streams including a high quality video stream and a low quality video stream are simultaneously transmitted to the mobile communication device over the wireless network. All of the video streams carry the same video content but with different video quality. The high quality video stream is transmitted with a relatively low margin and the low quality video stream is transmitted with a relatively high margin. The mobile communication device can select the high quality video stream when channel conditions are favorable, and may select the low quality video stream when the channel conditions are not good enough to support the high quality video stream.

摘要： A method for providing error correction of media packets. Service nodes associated with a core network segment use a first error correction process, and service nodes associated with an access network segment use a second error correction process. Service nodes associated with a local network segment may use a third error correction process. The present invention utilizes different error correction processes on different network segments as appropriate. Service nodes may receive indicators from monitoring agents that error correction is insufficient and, in response, a service node may increase an amount of error correction associated with a network segment. Media packets may be interleaved in a forward error correction (FEC) block in a manner that increases an amount of packet recovery.

摘要： An encoding system is configured to allow data to be transmitted at one of two selectable bit-error-rate quality factors. The first bit-error-rate quality factor selection corresponds to the conventional ATSC FEC encoding systems, and the second bit-error-rate quality factor selection provides an ATSC-like FEC encoding scheme that substantially improves the bit-error-rate. The first quality factor selection effects a 2/3 trellis encoding, whereas the higher quality factor selection effects a 1/3 trellis encoding. Because the high-quality trellis encoding rate of 1/3 is half the lower-quality trellis encoding rate of 2/3, the data rate of this high-quality encoded bit-stream is half that of the conventional lower-quality encoded bit-stream. The 1/3 trellis encoding is effected using an ATSC-compatible encoding and a modified symbol mapping. The encoding scheme provides 2:1 data redundancy and the symbol mapping provides a maximum distance for the redundant encoding. By combining techniques that each decrease the likelihood of an uncorrectable error at the receiver, the substantial improvement in bit-error-rate can be achieved. At the receiver, a single trellis decoder with different metric tables is used to decode the two bit-streams, thereby providing substantial compatibility with ATSC-compatible receivers.
摘要翻译：编码系统被配置为允许以两个可选误码率质量因子中的一个发送数据。第一个误码率质量因子选择对应于传统的ATSC FEC编码系统，第二个误码率质量因子选择提供了基本上提高了误码率的类似ATSC的FEC编码方案。第一个品质因素选择会影响2/3网格编码，而较高品质因子选择会影响1/3网格编码。因为1/3的高质量网格编码率是2/3的较低质量网格编码率的一半，因此该高质量编码比特流的数据速率是传统较低质量编码比特流的一半，流。使用ATSC兼容编码和修改的符号映射来实现1/3网格编码。编码方案提供2：1数据冗余，符号映射为冗余编码提供最大距离。通过组合各种技术，可以降低接收机处的不可校正误差的可能性，可以实现误码率的实质性改善。在接收机处，使用具有不同度量表的单个网格解码器对两个比特流进行解码，从而提供与ATSC兼容接收机的实质兼容性。

摘要： The object-oriented coder (104) discriminates resource (Fig.3) allocation between objects and non-objects for video messaging applications over wireless networks. The object-oriented coder (104) executes a rate control algorithm, an unequal error protection algorithm, and an error concealment algorithm. In the rate control algorithm, an iterative feedback rate control scheme is used in which quantization values of object and non-object data are held constant. In the unequal error protection algorithm, the bit stream is partitioned by object macroblocks and non-object macroblocks. In the error concealment algorithm, five bits of QUANT values of each GOB are used for representing location and motion vectors of the object in the next frame, since the quantization value is constant. The five bits are not used for quantization value. The five bits are used for error concealment to avoid bit rate overhead. The object-oriented coder increases encoding delay, but this increase is acceptable in messaging.
摘要翻译：面向对象编码器（104）通过无线网络区分视频消息应用的对象与非对象之间的资源（图3）分配。面向对象编码器（104）执行速率控制算法，不等差错保护算法和错误隐藏算法。在速率控制算法中，使用迭代反馈速率控制方案，其中对象和非对象数据的量化值保持不变。在不等错误保护算法中，比特流由对象宏块和非对象宏块分割。在误差隐藏算法中，由于量化值不变，所以每个GOB的QUANT值的5位用于表示下一帧中的对象的位置和运动矢量。这五位不用于量化值。这五个位用于错误隐藏以避免比特率开销。面向对象的编码器增加编码延迟，但这种增加在消息传递中是可以接受的。
