“…At the same time, most of the syntaxes used by both standards follow a similar format. Some of the key structural similarities and differences between the two coding standards can be summarized as below (for a more in-depth description, refer to [15,16]). …”

High Efficiency Video Coding (HEVC) is the most recent video codec standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of this newly introduced standard is for catering to high-resolution video in low bandwidth environments with a higher compression ratio. This paper provides a performance comparison between HEVC and H.264/AVC video compression standards in terms of objective quality, delay, and complexity in the broadcasting environment. The experimental investigation was carried out using six test sequences in the random access configuration of the HEVC test model (HM), the HEVC reference software. This was also carried out in similar configuration settings of the Joint Scalable Video Module (JSVM), the official scalable H.264/AVC reference implementation, running on a single layer mode. According to the results obtained, the HM achieves more than double the compression ratio compared to that of JSVM and delivers the same video quality at half the bitrate. Yet, the HM encodes two times slower (at most) than JSVM. Hence, it can be concluded that the application scenarios of HM and JSVM should be judiciously selected considering the availability of system resources. For instance, HM is not suitable for low delay applications, but it can be used effectively in low bandwidth environments.

Guaranteing the quality of face object in video call is the key task for video coding systems under the constrained bandwidth of network. Conventionally, the face object is divided into disperse blocks under the hybrid coding framework. Therefore, the characteristics of the complete face object have not been fully used. Meanwhile, it is difficult to predict the complex affine transformations such as rotation and scaling of the face object in neighboring frames based on the current translation motion model.In this paper, we propose an improved video coding scheme for video call. The complex transformation of complete face object is used to improve the compression effect. Experimental results show that our proposed method has better performance compared with HM12.0, the bits rate saving of face region is up to 19.59% under the similar visual quality .

“…In H.264/AVC, deep temporal scalability hierarchies, e.g., typically more than four temporal levels, require the use of long-term reference pictures, adaptive reference picture marking, and reference picture list modification. Adaptive reference picture marking is somewhat vulnerable to picture losses [2], and hence the use of decoded reference picture marking SEI messages is recommended in error-prone environments. Furthermore, H.264/AVC includes no identification of the temporal level in NAL unit header or slice header, as the subbitstream extraction for temporal scalability was not considered a normative feature of the standard at the time of developing the specification.…”

“…Similar to H.264/AVC, HEVC is a hybrid video codec based on predictive transform coding and an entropy coding step. As H.264/AVC, also HEVC defines a network abstraction layer (NAL) [2], which provides the primary interface to system level technologies.…”

Abstract-This paper describes the integration of High Efficiency Video Coding (HEVC) into end-to-end multimedia systems, formats, and protocols such as Real-time transport Protocol, the transport stream of the MPEG-2 standard suite, and dynamic adaptive streaming over the Hypertext Transport Protocol. This paper gives a brief overview of the high-level syntax of HEVC and the relation to the Advanced Video Coding standard (H.264/AVC). A section on HEVC error resilience concludes the HEVC overview. Furthermore, this paper describes applications of video transport and delivery such as broadcast, television over the Internet Protocol, Internet streaming, video conversation, and storage as provided by the different system layers.
